Previous research has shown the relationship between loneliness and affect, as well as the relationship between trait loneliness and state loneliness. However, none has investigated how social context affects the association between loneliness and affect. The current study aims to examine the association between trait loneliness, state loneliness and momentary affects in different social contexts.Participants aged 15-24 were randomly recruited from a Hong Kong epidemiological study to participate in an Experience Sampling Method (ESM) study. The group was divided in two based on the mean trait loneliness score (UCLA Loneliness Scale) at baseline. State loneliness, momentary positive (PA) and negative affect (NA) and social context were assessed using ESM. Multilevel logistic regression was used to analyze the association between momentary affect, state loneliness and trait loneliness in various social contexts.HL (high lonely) and LL (low lonely) groups consisted of 79 participants (44.6%) and 98 participants (55.4%) respectively. HL group had lower PA and higher NA, as well as a higher state loneliness than LL group. HL group had a lower state loneliness when being with intimate company compared to alone. LL group only had a higher PA when being with intimate company compared to non-intimate company and alone respectively.Adolescents with high level of trait loneliness experienced higher PA, momentary loneliness and lower NA compared to those with low level of trait loneliness. The quality of social company is crucial in allowing one to experience different degrees of PA and momentary loneliness.

Stressors at the population level affect women more than men. The influence of prolonged stressors on mental disorders in women is yet unknown, especially when social movements and pandemics coexist.This study analysed data from an online mental health self-help service for women in Hong Kong between May and September 2020. We collected demographic data, PTSD symptoms, and exposure to social unrest-related traumatic events (TEs), pandemic-related traumatic events (PEs), and personal stressful life experiences (SLEs). Multiple logistic regression was performed to examine the links between TEs, PEs, and SLEs and PTSD.The study found that 38.4% of 751 women had moderate-to-severe depressive symptoms and 23.8% had probable PTSD. The most common TEs, PEs, and SLEs were violence via media, major physical health concerns, and plans thwarted due to COVID-19, respectively. Younger age, less education, unemployment, and more stressors (individually or collectively, except for high TEs and PEs) were linked to increased odds of moderate-to-severe depressive symptoms. TEs and PEs increased the risk of probable PTSD only when SLEs were present.The non-random samplinging procedure reduced the generalisability to the entire women population.Exposure to social conflicts and pandemics may increase depressive and PTSD symptoms in women. Developing mental health services for women should consider the impact of concurrent major events.

Mindfulness meditation (MM) and its alignment with the mind-body perspective of health in Chinese cultures indicate its potential to benefit Chinese patients with psychosis. This is the first systematic review and meta-analysis to address the following questions: (1) Does MM improve clinical, well-being, and third-wave outcomes (i.e., mindfulness, acceptance, and compassion levels) among Chinese patients with psychosis? (2) What are the patient- and/or intervention-specific factors that moderate the efficacy of MM? (3) Are improvements on third-wave outcomes associated with improvements on clinical and well-being outcomes? (4) What are the mechanisms underlying the effects of MM? Evidence synthesized from 23 relevant articles (20 studies) involving 1749 patients showed that (1) MM improved a wide range of patients' outcomes, most consistently and sustainably for insight, rehospitalization duration, recovery rate, and social functioning; (2) age and duration of illness, but not the cumulated intervention hours, moderated the overall efficacy of MM; (3) post-MM improvements on mindfulness and on clinical and well-being outcomes were related, and (4) the effects of MM on patients' outcomes may be driven by its ability to promote positive changes in personal growth and enhance one's coping with the illness and its symptoms. Our data showed preliminary support for the benefits of MM in Chinese patients with psychosis. However, results should be considered in light of the varying quality of included studies and their heterogeneity in multiple aspects. Further research is needed to deduce the sustainability of MM's effects, its active ingredients, underlying mechanisms, and additional moderators of its efficacy.

Ideas of reference (IOR) are often implicated in predicting psychosis onset. They have been conceptualized to present on a continuum, from oversensitive psychological reactions to delusional thoughts. It is however unknown to what extent IOR may be triggered by collective environmental stress. We obtained timely data from 9873 individuals to assess IOR in relation to trauma exposure in the 2019–2020 social unrest in Hong Kong. Two levels of IOR are distinguished: attenuated IOR (IOR-A), being the experience of feeling particularly referred to within a group; and exclusive IOR (IOR-E), the experience of feeling exclusively referred to while others are not. Logistic regressions showed that event-based rumination was a shared predictor for IOR-A (OR = 1.07, CI = 1.03–1.10) and IOR-E (OR = 1.09, CI = 1.02–1.17). For IOR-A, three categories of social unrest-related traumatic events (TEs) were significant predictors, including being attacked or having experienced sexual violence (OR = 4.14, CI = 1.93–8.85), being arrested (OR = 4.48, CI = 1.99–10.10), and being verbally abused (OR = 2.66, CI = 1.28–5.53). Being arrested was significant for IOR-E (OR = 3.87, CI = 1.03–14.52), though not when rumination was included. Education level also significantly predicted IOR-E (OR = 0.72, CI = 0.52–0.99). Further analysis revealed that rumination significantly mediated between TEs and IOR severity (β = 0.26, SE = 0.01, CI = 0.24–0.28). The findings are consistent with the hypothesis that IOR-A and IOR-E occur as levels on a continuum, but each has some distinctive correlates. Extrinsic events may play a more prominent role in IOR-A, while intrinsic factors, such as cognitive capacity, may play a more prominent role in IOR-E. The involvement of rumination across the IOR spectrum suggests an opportunity for intervention.

This study explored the 10-year trajectories and outcomes of negative symptoms in patients with first-episode schizophrenia-spectrum disorder. Patients were from the historical control study comparing 10-year outcomes between standard care and early intervention services. A total of 298 patients were identified, 214 were successfully interviewed at 10-year follow-up for clinical and functional outcomes and 209 patients were included for final analyses. Information from clinical records were obtained systematically using standardized data entry forms. These information including negative symptoms, hospitalization and employment, monthly for year 1–3 and trimonthly for the year 4–10. Hierarchical cluster analysis was used to explore the 10-year negative symptom clusters. Demographics and early clinical characteristics related to the cluster memberships and different components of negative symptom at 10-year follow-up were further explored. The cluster analysis identified three longitudinal clusters of negative symptoms and 15% of patients were in the relapsed group. There was no difference in cluster membership between the intervention groups. Male gender and duration of hospitalizations in year four were found to be significant determinants of relapse negative symptoms. Lower education level, higher year-one negative symptom score and more months of unemployment during the first 3 years predicted overall negative symptoms at 10-year follow-up. Male gender was found to be a predictor only for avolition and anhedonia and duration of untreated psychosis only predicted anhedonia. These results highlighted the heterogeneity of longitudinal outcomes and the importance of personalized interventions.

Effort-based decision-making has recently been proposed as a potential mechanism contributing to motivational deficits (amotivation) in psychotic disorder. Previous research has identified altered effort allocation in chronic schizophrenia, but produced mixed results regarding its relationship with amotivation. No study has investigated effort allocation in first-episode psychosis (FEP). We examined effort-based decision-making in 45 clinically-stabilized FEP patients and 45 demographically-matched controls, using Effort-Expenditure for Reward Task (EEfRT) which measures allocation of physical effort for monetary reward at varying magnitude and probability levels. Our results showed that FEP patients did not demonstrate overall reduction in effort expenditure but displayed reduced willingness to expend effort for high-value/high-probability reward as compared to controls. In particular, such selective effort-related impairment was most pronounced in patients with high levels of amotivation. Furthermore, reduced allocation of greater effort for higher probability reward was related to poorer psychosocial functioning. Decreased effort exertion was generally unrelated to other symptom dimensions, self-report anhedonia, antipsychotic dose and cognitive deficits. This study thus provides the first evidence of effort-based decision-making impairment in FEP, and indicates that first-episode patients were not generally effort-averse but exhibited inefficient effort allocation by failing to make high-effort choices to maximize reward receipt. Our findings affirm the critical role of amotivation on aberrant effort allocation, and support the link between laboratory-based effort-cost measures and real-world psychosocial functioning in medicated FEP. Further longitudinal research is required to clarify trajectory of suboptimal effort allocation and its potential utility in predicting amotivation and functional outcomes in the early course of illness.

Achieving functional recovery in patients with psychosis is a challenge in clinical practice. Investigating the complex interplay between cognition, symptoms, insight and functional outcome in first episode psychosis will be crucial to understanding the factors leading to better functioning.In this 12-month prospective follow-up study, we investigated how cognition, clinical symptoms, and insight into illness affected overall functioning in 160 patients with first episode psychosis recruited from the Early Assessment Service for Young People with Psychosis (EASY) in Hong Kong from July 1, 2014 to June 30, 2016. Cognition was assessed at baseline while symptoms, insight, and functioning were assessed at 12-month follow-up. Structural equation modelling was used to examine the direct and indirect relationships between functioning and other latent constructs.Symptoms (negative symptoms and general psychopathology) and insight were shown to be significant mediators between cognition and functioning. The significant direct relationship between cognition and functioning (β = 0.387; p 0.001) became insignificant (β = 0.079; p = 0.578) after including symptoms and insight in the model. Symptoms and insight were significantly associated with cognition (symptoms, β = -0.469; p 0.001; insight, β = -0.372; p 0.001) and predicted functioning (symptoms, β = -0.558; p 0.001; insight, β = -0.264; p 0.01).Symptoms and insight mediated the effects of cognition on functioning. Interventions for improving functioning in patients with first episode psychosis should target not only cognition but also symptoms and insight.

Despite the popularity of interprofessional education, the empirical and theoretical development of its scholarship and science is just emerging. This may be caused in part by the non-availability of measures that can be used by researchers in this field. This study aimed to contribute to the psychological theorizing of interprofessional education by uncovering the psychometric properties of Perceived Locus of Causality adapted to Interprofessional Education (PLOC-IPE) in healthcare education and provide a comprehensive guide on how this can be used to advance the IPE research agenda.Confirmatory factor analysis (quantitative design) was used to examine the acceptability of psychometric properties of PLOC-IPE. Data were collected through questionnaires administered at two different time points. The participants consisted of 345 students from Chinese Medicine, Clinical Psychology, Medicine, Nursing, Pharmacy, and Social Work from a university in Hong Kong.Based on confirmatory factor analysis, results of within-network construct validity showed good psychometric properties of PLOC-IPE while between-network validity indicated that the scale can predict IPE-related outcomes. Students' intrinsic motivation in IPE positively predicted emotional engagement and negatively predicted emotional disaffection, demonstrating the applicability of the newly validated PLOC-IPE. Amotivation was a negative predictor of emotional engagement and a positive predictor of emotional disaffection.Findings support the acceptability of PLOC when adapted to IPE. PLOC-IPE obtained acceptable psychometric properties as a measure of students' academic motivation in IPE. It is an adapted scale that can be used to understand self-determined motivation in the context of IPE in health and social care education. A guide on how PLOC-IPE can be a means by which researchers can contribute to the advancement of scholarship of IPE was provided.

The long-term recovery rate of patients with schizophrenia-spectrum disorders has been persistently low despite the implementation of early intervention (EI) services internationally. It is, therefore, important to identify the modifiable factors during the early stage of the illness that predict long-term remission and recovery. The aim of this study is to explore the predictive value of the early stage clinical factors on the clinical remission and functional recovery at 10-year follow-up of patients with schizophrenia-spectrum disorders who received a 2-year EI service. Patients who received the EI service throughout the region of Hong Kong between 1st July 2001 and 30th June 2002 and with a diagnosis of schizophrenia-spectrum disorder were identified from the centralized hospital database (Clinical Management system, CMS). Semi-structured clinical interview was conducted at 10-year follow-up with a successful interview rate of 74.3% (n = 107). Clinical data was systematically retrieved each month for the first three years from the CMS and written clinical records using a standardized data entry form based on operationalized definitions. Results found shorter duration of untreated psychosis (DUP) predicted long-term clinical remission; higher educational level and shorter period of unemployment during the initial three years of the illness predicted functional recovery. Higher educational level, longer period of employment and planned medication discontinuation during the initial three years predicted complete recovery. The current study demonstrates the long-term impact of DUP and suggests improvement of employment during the early stage of illness could be a potential target for further improvement of the service.

This study explored the 10-year pattern of relapse of patients with first-episode schizophrenia-spectrum disorders (FES), predictors and outcomes of early and late relapse.Patients received EIS (N = 148) in Hong Kong between 1 July 2001 and 30 June 2002 were matched with those who entered standard care (N = 148) one year before. Relapse information over 10 years were obtained and 209 patients were interviewed at 10-year follow-up. Predictors of early relapse ([ER] relapse in initial three years) and late relapse group ([LR] relapse in year 4-10) and their differential outcomes were explored.Fifty-six patients (26.8%) were relapse-free over 10 years with more EIS patients. Among the relapsed patients, 63.6% were ER patients who had the poorest longitudinal outcomes, including higher suicide attempts, violence episodes, more hospitalization and lower employment, whereas the LR patients do not differ much from the no relapse group. Relapse-free patients required less hospitalization in the first episode and lower antipsychotic dosage. The LR patients had less positive symptoms in year one but longer first-episode hospitalization and higher antipsychotic dosage.Delaying the first relapse may help to improve the long-term outcomes. Good response to antipsychotic medications was associated with relapse-free over long-term. However, sufficient antipsychotic medications with good symptomatic control during the early stage of the illness is crucial for relapse prevention for other patients. These findings highlight illness heterogeneity and the importance in differential use of antipsychotics in relapse prevention.

Negative symptoms are a core psychopathological dimension of psychotic disorders. Previous research on primary negative symptoms (PNS) mostly focused on chronic samples. Data regarding premorbid, clinical and cognitive correlates of PNS in the early illness course are limited and inconsistent. In this study, we assessed 355 Hong Kong Chinese adult patients presenting with first-episode psychosis (FEP) to early intervention service with an aim to examine the prevalence of PNS and its relationships with premorbid adjustment, clinical and cognitive profiles. PNS was defined as the presence of clinically significant negative symptoms excluding depression, positive symptoms and extrapyramidal signs. Results showed that 14.6% of patients exhibited PNS at service entry. PNS group had poorer premorbid social functioning, lower level of insight, and worse performance in Modified Wisconsin Card Sorting and digit symbol tests than non-PNS group. Logistic regression analysis showed that premorbid social functioning and digit symbol test score were independently associated with PNS. Our findings thus indicate that PNS are frequently observed in FEP patients. Deficits in proceeding speed, alongside impaired premorbid social functioning, might be specifically related to PNS in the early illness stage.

Background Research on antipsychotic medication non-adherence in first-episode psychosis patients tends to examine non-adherence behaviors and attitudes together. Nonetheless, attitudes do not always directly translate into behaviors. We examined the baseline predictors for antipsychotics non-adherence behaviors and attitudes separately in a first-episode psychosis cohort. We also included cognitive impairments as one of the predictor variables as this domain is rarely explored in adherence studies. Method Participants were 313 adult-onset psychosis patients recruited from the Jockey Club Early Psychosis project in Hong Kong. Demographic, premorbid, clinical, and cognitive characteristics were first assessed at baseline. Six months later, participants completed a 14-item Medication Compliance Questionnaire, which was a modified and Cantonese-translated version of the Medication Adherence Rating Scale that includes items pertaining to both adherence behaviors and attitudes. Results Rates of poor adherence behaviors and negative adherence attitudes were 17.6% and 27.8%, respectively. Determinants of poor adherence behavior included more severe positive symptoms, hospitalization at onset of illness, and poorer engagement in extended social network. As for negative adherence attitude, determinants included more severe general psychopathology, poorer insight, more psychic medication side-effects, and poorer performance on backward digit span test and WAIS-R information test. Conclusions The risk factors for non-adherence behaviors and attitudes are different and they should all be taken into careful consideration while formulating appropriate intervention programs to tackle the adherence problem in adult onset psychosis.

Background Functional remission (FR) is an intermediate and necessary step toward recovery, but is understudied in first-episode psychosis (FEP). We aimed to examine the rate and predictors of FR in FEP patients in the context of a randomized-controlled trial (RCT) comparing a 1-year extension of early intervention (Extended EI, 3-year EI) with step-down psychiatric care (SC, 2-year EI). Methods One hundred sixty Chinese patients were recruited from a specialized EI program for FEP in Hong Kong after they have completed this 2-year EI service, randomly allocated to Extended EI or SC, and followed up for 12 months. Assessments on premorbid adjustment and personality, clinical profiles, functioning, and treatment characteristics were conducted. FR was operationalized as simultaneous fulfillment of attaining adequate functional levels (measured by Social and Occupational Functioning Scale and Role Functioning Scale) and competitive employment at 6 and 12 months. Data analysis was based on 156 subjects who completed follow-up functional assessments. Results Thirty-one (19.9%) patients achieved FR status. Multivariate binary regression analysis showed that female gender, lower degrees of premorbid schizoid-schizotypal traits, Extended EI treatment condition, lower levels of positive symptoms at intake, and better baseline functioning independently predicted FR. Conclusion This is the first RCT providing supportive evidence to an extension of EI service beyond 2-year treatment duration on further enhancing the likelihood of FR attainment in FEP. Our findings that only approximately 20% of patients achieved FR indicate an unmet therapeutic need for promoting sustained adequate functional improvement in the early stage of psychotic illness.

Summary Background The long-term consequences of discontinuing antipsychotic medication after successful treatment of first-episode psychosis are not well studied. We assess the relation between early maintenance therapy decisions in first-episode psychosis and the subsequent clinical outcome at 10 years. Methods This is a 10 year follow-up study, spanning Sept 5, 2003, to Dec 30, 2014, of a randomised, double-blind trial in seven centres in Hong Kong in which 178 patients with first-episode psychosis with full positive symptom resolution after at least 1 year of antipsychotic treatment were given maintenance treatment (n=89; oral quetiapine 400 mg daily) or early treatment discontinuation (n=89; placebo) for 12 months. After the trial, patients received naturalistic treatment. Overall this cohort of patients will have received about 3 years of treatment before entering the follow-up phase of the study: about 2 years of maintenance treatment before study entry and 1 year of treatment in the trial. The primary outcome of this follow-up was the proportion of patients in each group (including those for whom direct follow-up was not available) with good or poor long-term clinical outcomes at 10 years, with poor outcome defined as a composite of persistent psychotic symptoms, a requirement for clozapine treatment, or death by suicide. The randomised trial was registered with ClinicalTrials.gov, number NCT00334035, and the follow-up study was registered with ClinicalTrials.gov, number NCT01926340. Findings Poor 10 year clinical outcome occurred in 35 (39%) of 89 patients in the discontinuation group and 19 (21%) of 89 patients in the maintenance treatment group (risk ratio 1·84, 95% CI 1·15–2·96; p=0·012). Suicide was the only serious adverse event that occurred in the follow-up phase (four [4%] patients in the early discontinuation group vs two [2%] in the maintenance group). Interpretation In patients with first-episode psychosis with a full initial response to treatment, medication continuation for at least the first 3 years after starting treatment decreases the risk of relapse and poor long-term clinical outcome.

Previous research investigating the relationships between avolition, cognition and functioning in schizophrenia mostly focused on chronic samples and were cross-sectional in design. Impacts of avolition and cognition on longitudinal functional outcome in first-episode patients are under-studied. We assessed 114 Chinese aged 18-55 years presenting with first-episode schizophrenia-spectrum disorder aiming to identify baseline predictors of 1-year functional outcome. Results showed that both avolition and global cognition independently predicted functioning, with avolition being the strongest predictor above and beyond cognition and other symptom dimensions. Our findings indicate the central role of in determining longitudinal functional status in the early illness stage.

Background Self-perceived cognitive dysfunction is under-recognized in clinical practice and under-studied in schizophrenia, particularly in the early illness stage. Findings on the relationship between subjective and objective cognitive measures were inconsistent. This study aimed to examine psychometric properties of a newly developed scale, Subjective Cognitive Impairment Scale (SCIS) and to investigate the relationship of self-reported ratings with objective test performance in first-episode schizophrenia. Methods One hundred one Chinese patients aged 18 to 64 years presenting with first episode schizophrenia-spectrum disorder were studied. A comprehensive set of assessments examining objective cognitive functioning, clinical and treatment characteristic were administered. Internal consistency, factor structure and construct validity of SCIS were evaluated. Correlations of scale score with objective cognitive measures, clinical and treatment variables were examined. Results A single-factor underlying the structure of SCIS items was demonstrated by principal components analysis. Cronbach's alpha coefficient for the scale was 0.92. SCIS score was positively correlated with depression and anxiety symptom severity, and duration of untreated psychosis. SCIS score was not associated with other symptom dimensions, insight and chlorpromazine equivalents. No significant correlations were observed between SCIS score and objective cognitive measures with the exception of letter-number span test. Conclusion Our results provided preliminary evidence in support of reliability and validity of SCIS in evaluating patient's cognitive complaints. A lack of correspondence between subjective and objective cognitive functioning suggested that they may represent two distinct constructs with potentially differential therapeutic implications. Further research is warranted to examine ecological validity and clinical utility of the scale.

Schizophrenia is associated with pronounced vocational impairment. Previous research has mostly focused on chronic patients and few studies were conducted to investigate predictors of work outcome in first-episode populations. The impact of cognitive dysfunction on employment outcome in early psychosis was under-studied. In this study, we prospectively followed up 93 patients aged 18-55 years presented with first-episode schizophrenia-spectrum disorder for 3 years with an aim to identify early clinical and cognitive predictors of vocational outcome. Pre-morbid adjustment, baseline symptomatology and cognitive functions, and employment outcome were assessed. Result indicated that approximately half of the patients (53.8%) were engaged in full-time work at intake and at 3 years. Pre-morbid adjustment, baseline occupational status and Wisconsin Card Sorting Test (WCST) performance were found to predict vocational outcome. Analysis on a subgroup of patients who were unemployed at intake showed that subjects who remained unemployed over 3 years had poorer WCST performance and more severe positive symptoms at baseline than those having job attainment during follow-up. Our results thus confirmed predictive value of pre-morbid functioning and baseline occupational status on vocational outcome. In addition, our findings suggested that executive function might be a critical cognitive determinant of employment outcome in the early course of schizophrenia.

Studies have shown that early- and adult-onset schizophrenia patients differ in pre-morbid traits, illness presentation, psychopathology, and prognosis. We aimed to compare adult-onset patients (age range 26–55 years) with an adolescent-onset cohort (15–25 years) in demographics, illness presentation and functioning at baseline. Participants were from two territory-wide early intervention services for adolescent-onset ( n =671) and adult-onset psychosis patients ( n =360) in Hong Kong. The adolescent-onset cohort had their initial psychotic episode from 2001–2003; retrospective data collection was done through systematic case note review. The adult-onset cohort was recruited for a larger interventional study from 2009–2011; information was collected via face-to-face interviews. Adult-onset psychosis was significantly associated with more females, fewer smokers, more non-local birth, more full-time employment, better functioning, poorer medication adherence, more psychiatric hospitalization and fewer with schizophrenia than adolescent-onset psychosis (mean age: 20.4). The effect sizes were small, except for medication adherence where a robust effect was found. No group difference in DUP was found. The finding that adult-onset patients had better functioning challenges the view that adolescent- and adult-onset psychoses share a similar prognostic trajectory. Implications for adapting intervention processes for adolescent- and adult-onset psychosis are discussed.

Language disorganization is an important clinical indicator of acute psychosis, yet the longitudinal course and pathogenesis are not well understood. Executive dysfunction has been suggested as a vital contributor to formal thought disorder (FTD) and may serve as a stable predictor of symptomatic risk. The paper reports a one-year prospective study of language disorganization in sixty patients with first-episode schizophrenia-spectrum disorders and investigates executive function as a predictor of persistent FTD one year after illness onset. FTD was captured using the Clinical Language Disorder Rating Scale (CLANG), which segregates language abnormalities into three empirically validated levels: syntactic, semantic, and production. After one year, patients' syntactic and semantic deficits were substantially reduced, but production impairments persisted. Patients' improvement of semantic impairment was associated with reduced disorganized symptoms while production impairment was associated with negative symptoms. We further identified two different patterns of baseline executive function predictors for both residual semantic and production impairment. We found that sustained FTD at the semantic level was predicted by both sustained attention and planning at illness onset, while residual production failure was only predicted by sustained attention. In conclusion, the present paper documents the distinct characteristics of psycholinguistic levels in FTD and isolates two different patterns of executive function predictors for persistent semantic and production language disorganization at follow-up. The findings help to disentangle FTD dimensions at different levels of language production processes, which provide clinical implications for targeting patients at risk for prolonged FTD concordant upon executive dysfunction at illness onset.

Background Individuals with first-episode psychosis (FEP) have markedly elevated risk for suicide. Previous research on suicidality in early psychosis mainly focused on attempted and completed suicide. Data regarding risk factors for suicidal ideation, which is a common antecedent and predictor of suicide attempt, were limited. This study aimed to examine the prevalence of suicidal ideation and its relationships with clinical, neurocognitive and psychological factors in FEP patients. Method Eighty-nine Chinese patients aged 15 to 25 years presenting with FEP to specialized early intervention service were recruited. A comprehensive set of assessments examining pre-treatment illness characteristics, symptom severity, neurocognitive function, and psychological factors were administered. Current suicidal ideation and history of suicide attempt were systematically evaluated. Results Approximately 42% of patients expressed suicidal ideation after service entry. Univariate regression analyses found that suicidal ideation was significantly associated with past suicide attempt, depressive symptoms, emotion expressivity, hopelessness, future expectation, attentional impulsiveness, internal and external locus of control, and the likelihood of endorsing fear of social approval and survival and coping beliefs as reasons for living. Final multivariate model showed that previous suicide attempt, depression, less severe diminished expression, greater degree of hopelessness and lower level of internal locus of control independently predicted suicidal ideation. Conclusions Suicidal ideation was prevalent in FEP patients. Our findings implied that close monitoring and prompt intervention of those potentially modifiable risk factors for suicidal ideation including depression, hopelessness and perceived inadequate personal control may reduce suicide risk in the early course of psychotic illness.

Background The adverse effects of a long duration of untreated psychosis (DUP) have been explored in numerous short-term studies. These studies support the development of early interventions that reduce treatment delay and promote recovery. However, the enduring impact of DUP is largely unknown, partly due to the paucity of prospective long-term studies. Although the DUP–outcome relationship is commonly assumed to be linear, the threshold effect has not been adequately examined. Objective To explore the relationship between DUP and long-term symptomatic remission. Methods This was a prospective study of a cohort of 153 first-episode psychosis patients in Hong Kong at the 13-year follow-up. The patients were categorized into short (≤ 30 days), medium (31–180 days) and long (> 180 days) DUP groups. Results The long-term outcome was ascertained in 73% of the patients. Nearly half of the patients (47%) fulfilled the criteria for symptomatic remission. The short DUP group experienced a significantly higher remission rate over the course of the illness. The odds of long-term symptomatic remission was significantly reduced in the medium DUP (by 89%) and long DUP (by 85%) groups compared with the short DUP group. Further analysis showed that DUP had a specific impact on negative symptom remission. Conclusion The findings support the threshold theory that DUP longer than 30 days adversely impacts the long-term outcome. The present study is one of the few studies that confirmed the enduring impact of DUP on long-term outcomes based on well-defined criteria and adequate statistical adjustment.

Diminished expression (DE) is a core sub-domain of negative symptoms construct in schizophrenia. There is limited, yet inconsistent data regarding DE and its associations with cognition, particularly in the early illness course. This study aimed to examine cross-sectional and longitudinal relationships of DE with cognitive functions in first-episode schizophrenia utilizing a prospective design.Ninety-three Hong Kong Chinese aged 18 to 55 years presenting with first-episode schizophrenia-spectrum disorder were studied. Severity of DE was measured as sum of individual item scores indicative of affect flattening and alogia. Symptom evaluation was conducted at intake, after clinical stabilization of first psychotic episode, at 12, 24 and 36 months. Cognitive functions were evaluated at clinical stabilization, 12, 24 and 36 months.DE was significantly correlated with various cognitive functions in successive follow-up assessments. Regression analyses adjusting confounding effects of sex, pre-morbid adjustment, duration of untreated psychosis and chlorpromazine equivalents showed that DE was associated with performance on verbal fluency at 12 (p0.01) and 24 months (p0.05), visual reproduction at 24 (p0.05) and 36 months (p0.01), logical memory at 36 months (p0.05) and Modified Wisconsin Card Sorting test at 24 (p0.05) and 36 months (p0.05). Neither cross-lagged associations between DE and cognition nor significant correlations between changes in these two domains over three years were observed.DE and cognitive functions were correlated concurrently but no longitudinal associations between these two domains could be demonstrated. Our findings indicated that DE and cognitive impairment represented relatively independent domains of the illness with potentially distinctive therapeutic implications.

There has been increasing interest in studying the impact of physical activity on the psychological and physical well-being and functioning in patients with first-episode psychosis. The exploration of factors which contribute to physical activity in psychosis may open up opportunities for improvement of functional outcome. The purpose of this study was to examine the association between physical activity level and functioning in psychosis. A total of 283 patients with first-episode psychosis were recruited from a specialized early intervention service for adult-onset psychosis (Jockey Club Early Psychosis Project) in Hong Kong. The level of physical activity, sociodemographics and clinical characteristics was assessed at study entry. Functioning was assessed at 6-months period. Ninety-six (33.9%) patients were categorized as physically inactive, and 187 (66.1%) of them were physically active. Being physically inactive (β=0.163, P=0.003), having more positive and negative symptoms [SAPS total score (β=-0.161, P=0.005), and SANS total score (β=-0.202, P=0.001)], and having lower household income (β=0.207, P=0.001) at baseline predicted poorer functioning at 6months. Early intervention for psychosis should target to improve patients' physical activity level which may help subsequent functioning.

Hong Kong is among the first few cities in Asia to have implemented early intervention for psychosis in 2001. Substantial changes in psychosis service have since taken place. We reviewed available outcome data in Hong Kong, with reference to the philosophy of early intervention in psychosis, discussing experience and lessons learned from the implementation process, and future opportunities and challenges. Data accumulated in the past decade provided evidence for the benefits and significance of early intervention programmes: patients under the care of early intervention service showed improved functioning, milder symptoms, and fewer hospitalizations and suicides. Early intervention is more cost-effective compared with standard care. Stigma and misconception remains an issue, and public awareness campaigns are underway. In recent years, a critical mass is being formed, and Hong Kong has witnessed the unfolding of public service extension, new projects and organizations, and increasing interest from the community. Several major platforms are in place for coherent efforts, including the public Early Assessment Service for Young people with psychosis (EASY) programme, the Psychosis Studies and Intervention (PSI) research unit, the independent Hong Kong Early Psychosis Intervention Society (EPISO), the Jockey Club Early Psychosis (JCEP) project, and the postgraduate Psychological Medicine (Psychosis Studies) programme. The first decade of early intervention work has been promising; consolidation and further development is needed on many fronts of research, service and education.

Executive function impairment is a key cognitive deficit in schizophrenia. However, traditional neuropsychological tests of executive function may not be sensitive enough to capture the everyday dysexecutive problems experienced by patients. Additionally, existing literature has been inconsistent about longitudinal changes of executive functions in schizophrenia. The present study focuses on examining the longitudinal change of executive functions in schizophrenia using the Modified Six Elements Test (MSET) that was developed based on the Supervisory Attentional System model and shown to be sensitive to everyday dysexecutive problems. In the present study, MSET performance was assessed in 31 medication-naïve first-episode schizophrenic patients at four times over a period of three years, while the 31 normal controls were assessed once. Patients demonstrated impairment in MSET as compared to controls. Importantly, the MSET impairment persisted from the medication-naïve state to clinical stabilization and the three years following the first psychotic episode though patients improved in a conventional executive test (Modified Wisconsin Card Sorting Test). Performance was not related to intelligence, educational level, symptom changes, age-of-onset, or duration of untreated psychosis. Better MSET performance at medication-naïve state predicted improvement in negative and positive symptoms over the three-year period. These findings may suggest that MSET impairment is a primary deficit in schizophrenia that occurs early in the course of the illness and remains stable irrespective of clinical state for at least three years following the first episode of schizophrenia.

In The Lancet Psychiatry, Nav Kapur and colleagues1 analysed mental health service changes in England between 1997 and 2012, to investigate correlations with suicide rates. Importantly, the investigators identified that some organisational changes had a positive effect on reducing suicide rates, including the implementation of the NICE guidelines for depression. However, the study did not include two of the most important organisational changes during this time: the substantial reduction in psychiatry bed numbers and significantly reduced admission rates for affective disorders in the UK...
