Background:Substantial evidence supports an association between childhood maltreatment and suicidal behaviour. However, few studies have examined factors mediating this relationship among patients with unipolar or bipolar mood disorders.Methods:Depressive disorder and bipolar disorder (ICD-10-DCR) patients (n = 287) from the Helsinki University Psychiatric Consortium (HUPC) Study were surveyed on self-reported childhood experiences, current depressive symptoms, borderline personality disorder traits, and lifetime suicidal behaviour. Psychiatric records served to complement the information on suicide attempts. We examined by formal mediation analyses whether (1) the effect of childhood maltreatment on suicidal behaviour is mediated through borderline personality disorder traits and (2) the mediation effect differs between lifetime suicidal ideation and lifetime suicide attempts.Results:The impact of childhood maltreatment in multivariate models on either lifetime suicidal ideation or lifetime suicide attempts showed comparable total effects. In formal mediation analyses, borderline personality disorder traits mediated all of the total effect of childhood maltreatment on lifetime suicide attempts, but only one fifth of the total effect on lifetime suicidal ideation. The mediation effect was stronger for lifetime suicide attempts than for lifetime suicidal ideation (P = 0.002) and independent of current depressive symptoms.Conclusions:The mechanisms of the effect of childhood maltreatment on suicidal ideation versus suicide attempts may diverge among psychiatric patients with mood disorders. Borderline personality disorder traits may contribute to these mechanisms, although the influence appears considerably stronger for suicide attempts than for suicidal ideation.

BackgroundDepressive disorders are known to impair health-related quality of life (HRQoL) both in the short and long term. However, the determinants of long-term HRQoL outcomes in primary care patients with depressive disorders remain unclear.MethodsIn a primary care cohort study of patients with depressive disorders, 82% of 137 patients were prospectively followed up for five years. Psychiatric disorders were diagnosed with SCID-I/P and SCID-II interviews; clinical, psychosocial and socio-economic factors were investigated by rating scales and questionnaires plus medical and psychiatric records. HRQoL was measured with the generic 15D instrument at baseline and five years, and compared with an age-standardized general population sample (n = 3707) at five years.ResultsDepression affected the 15D total score and almost all dimensions at both time points. At the end of follow-up, HRQoL of patients in major depressive episode (MDE) was particularly low, and the association between severity of depression (Beck Depression Inventory [BDI]) and HRQoL was very strong (r = −0.804). The most significant predictors for change in HRQoL were changes in BDI and Beck Anxiety Inventory (BAI) scores. The mean 15D score of depressive primary care patients at five years was much worse than in the age-standardized general population, reaching normal range only among patients who were in clinical remission and had virtually no symptoms.ConclusionsAmong depressive primary care patients, presence of current depressive symptoms markedly reduces HRQoL, with symptoms of concurrent anxiety also having a marked impact. For HRQoL to normalize, current depressive and anxiety symptoms must be virtually absent.

BackgroundDistinguishing between symptoms of schizotypal (SPD) and borderline personality disorders (BPD) is often difficult due to their partial overlap and frequent co-occurrence. We investigated correlations in self-reported symptoms of SPD and BPD in questionnaires at the levels of both total scores and individual items, examining overlapping dimensions.MethodsTwo questionnaires, the McLean Screening Instrument (MSI) for BPD and the Schizotypal Personality Questionnaire Brief (SPQ-B) for SPD, were filled in by patients with mood disorders (n = 282) from specialized psychiatric care in a study of the Helsinki University Psychiatric Consortium. Correlation coefficients between total scores and individual items of the MSI and SPQ-B were estimated. Multivariate regression analysis (MRA) was conducted to examine the relationships between SPQ-B and MSI.ResultsThe Spearman's correlation between total scores of the MSI and SPQ-B was strong (rho = 0.616, P < 0.005). Items of MSI reflecting disrupted relatedness and affective dysregulation correlated moderately (rφ varied between 0.2 and 0.4, P < 0.005) with items of SPQ. Items of MSI reflecting behavioural dysregulation correlated only weakly with items of SPQ. In MRA, depressive symptoms, sex and MSI were significant predictors of SPQ-B score, whereas symptoms of anxiety, age and SPQ-B were significant predictors of MSI score.ConclusionsItems reflecting cognitive-perceptual distortions and affective symptoms of BPD appear to overlap with disorganized and cognitive-perceptual symptoms of SPD. Symptoms of depression may aggravate self-reported features of SPQ-B, and symptoms of anxiety features of MSI. Symptoms of behavioural dysregulation of BPD and interpersonal deficits of SPQ appear to be non-overlapping.

Objective:To study prevalence of and predictors for functional and work disability among primary care (PC) patients with depressive disorders in prospective long-term follow-up.Methods:The Vantaa Primary Care Depression Study followed up prospectively 137 patients with depressive disorders for 5 years with a life chart. Information on level of functioning in general and in different dimensions, employment, sick leaves and disability pensions were obtained from interviews and patient records.Results:Level of functioning and work ability were strongly associated with time spent depressed and/or current severity of depression. Patients who belonged to the labour force at baseline spent one-third of the follow-up off work due to depression; two-thirds were granted sick leaves, and one-tenth a disability pension due to depression. Longer duration of depression, co-morbid disorders and having received social assistance predicted dropping out from work.Conclusion:Duration of depressive episodes appears decisive for long-term disability among PC patients with depression. Patients spent one-third of the follow-up off work due to depression, and remaining outside the labour force is a common outcome. Psychiatric and somatic co-morbidities, education and socio-economic means influence the level of functioning and ability to work, but are not equally important for all areas of life.

BackgroundHow different ways of assessing suicidal ideation influence its prevalence, correlates and predictive validity among patients with major depressive disorder (MDD) remains unclear.MethodsWithin the Vantaa Primary Care Depression Study (PC-VDS, 91 patients) and the Vantaa Depression Study (VDS, 153 psychiatric out-and 41 inpatients), suicidal ideation was assessed with the Scale for Suicidal Ideation (SSI), Hamilton Depression Scale (HAM-D) item 3 and Beck Depression Inventory (BDI) item 9, and by asking whether patients had seriously considered suicide during the episode. The positive and negative predictive values (PPV, NPV) for suicide attempts during a six-month follow-up were investigated.ResultsDepending on the setting, 56–88% of patients had suicidal ideation in some of the assessments, but only 8–44% in all of them. Agreement ranged from negligible to moderate (kappa 0.06–0.64), being lowest among primary care patients. The correlates of suicidal ideation overlapped. No assessment had optimal sensitivity, specificity, PPV and NPV. Nevertheless, PPVs ranged up to 43%.ConclusionsWhich MDD patient is classified as having suicidal ideation depends strongly on the method of assessment, with the greatest variation likely in primary care. Differences in assessments may cause inconsistency in risk factors. Predicting suicide attempts is difficult, but not futile.

Few studies have investigated the relationship of temperament and character, as conceptualized in the Temperament and Character Inventory–Revised (TCI-R), to symptoms of depression and anxiety in the general population. In this study a random sample of subjects (20 to 70 years), in two Finnish cities, were surveyed with the TCI-R, Beck Depression and Anxiety Inventories, plus questions related to diagnosed lifetime mental disorders, health care use for psychiatric reasons during the past 12 months, and history of mental disorders in first-degree relatives. Altogether 347 subjects (38.6%) responded. Of the TCI-R dimensions, Harm Avoidance correlated with symptoms of depression (rs = 0.555, p < 0.001), anxiety (rs= 0.560, p < 0.001), self-reported lifetime mental disorder (rs = 0.272, p< 0.001), health care use for psychiatric reason during the past 12 months (rs = 0.241, p< 0.001) and family history of mental disorder (rs = 0.202, ps = -0.495, p< 0.001), anxiety (rs = -0.458, p < 0.001), lifetime mental disorder (rs = 0.225, p< 0.001) and health care use (rs = -0.135, p = 0.013). Overall, Harm Avoidance and Self-directedness seem to associate moderately with depressive and anxiety symptoms, and somewhat predict self-reported use of health services for psychiatric reasons, and lifetime mental disorder. High harm avoidance may associate with a family history of mental disorder.

This study investigated the differences in clinical characteristics between suicide attempters referred or not referred to psychiatric consultation after a suicide attempt and factors affecting such referral to psychiatric aftercare after attempted suicide. All 1198 consecutive suicide attempters treated in hospital emergency rooms in Helsinki during a 12-month period were identified. Data were gathered on any psychiatric consultation after the attempt and on all health care contacts 1 year before and after the index attempt. We found that half of the suicide attempters who were not referred to psychiatric consultation were without any aftercare recommendation and treatment contact soon after their attempt. Factors predicting referral to psychiatric consultation were age, psychotic disorder, lack of substance use disorder and, most strongly, the hospital where the suicide attempt was treated. Although the characteristics of a patient attempting suicide do play a role in determining whether a psychiatric consultation will take place or not, the most important factor is the consultation practices of the particular hospital. This in turn influences the probability of adequate aftercare.

IntroductionAlthough suicidal behavior is very common in bipolar disorder (BD), few long-term studies have investigated incidence and risk factors of suicide attempts (SAs) specifically related to illness phases of BD.ObjectivesWe examined incidence of SAs during different phases of BD in a long-term prospective cohort of bipolar I (BD-I) and II (BD-II) patients and risk factors specifically for SAs during major depressive episodes (MDEs).MethodsIn the Jorvi bipolar study (JoBS), 191 BD-I and BD-II patients were followed using life-chart methodology. Prospective information on SAs of 177 patients (92.7%) during different illness phases was available up to five years. Incidence of SAs and their predictors were investigated using logistic and Poisson regression models. Analyses of risk factors for SAs occurring during MDEs were conducted using two-level random-intercept logistic regression models.ResultsDuring the five-year follow-up, 90 SAs per 718 patient-years occurred. Compared with euthymia the incidence was highest, over 120-fold, during mixed states (765/1000 person-years [95% confidence interval (CI) 461–1269]) and also very high in MDEs, almost 60-fold (354/1000 [95%CI 277–451]). For risk of SAs during MDEs, the duration of MDEs, severity of depression and cluster C personality disorders were significant predictors.ConclusionsIn this long-term study, the highest incidences of SAs occurred in mixed phases and MDEs. The variations in incidence rates between euthymia and illness phases were remarkably large, suggesting that the question “when” rather than “who” may be more relevant for suicide risk in BD. However, risk during MDEs is likely also influenced by personality factors.Disclosure of interestThe authors have not supplied their declaration of competing interest.

IntroductionSubstantial evidence supports association between childhood maltreatment and suicidal behaviour, however, a limited number of studies have examined psychological mechanisms mediating the relationship among patients with mood disorders.ObjectiveTo investigate directly the potential intermediating mechanisms between childhood maltreatment and suicidal behaviour among patients with mood disorders.AimsWe examine by formal mediation analyses, if:– the effect of childhood maltreatment on suicidal behaviour is mediated through borderline personality disorder traits;– the mediation effect differs between lifetime suicidal ideation and lifetime suicide attempts.MethodsDepressive disorder and bipolar disorder (ICD-10-DCR) patients (n = 287) from the Helsinki university psychiatric consortium (HUPC) Study were surveyed on self-reported childhood experiences, current depressive symptoms, borderline personality disorder traits and lifetime suicidal behaviour.

In formal mediation analyses, borderline personality disorder traits mediated all of the total effect of childhood maltreatment on lifetime suicide attempts, but only 21% of the total effect on lifetime suicide ideation. The mediation effect was stronger for lifetime suicide attempts compared to ideation (P = 0.002) and independent of current depressive symptoms.ConclusionsThe mechanisms of the effect of childhood maltreatment on suicidal ideation and attempts may diverge among psychiatric patients with mood disorders. Borderline personality disorder traits may contribute to these mechanisms, although the influence appears considerably stronger for suicide attempts than for suicide ideation.Disclosure of interestThe authors have not supplied their declaration of competing interest.

SummaryPsychological autopsy is one of the most valuable tools of research on completed suicide. The method involves collecting all available information on the deceased via structured interviews of family members, relatives or friends as well as attending health care personnel. In addition, information is collected from available health care and psychiatric records, other documents, and forensic examination. Thus a psychological autopsy synthesizes the information from multiple informants and records. The early generation of psychological autopsies established that more than 90% of completed suicides have suffered from usually co-morbid mental disorders, most of them mood disorders and/or substance use disorders. Furthermore, they revealed the remarkable undertreatment of these mental disorders, often despite contact with psychiatric or other health care services. More recent psychological autopsy studies have mostly used case-control designs, thus having been better able to estimate the role of various risk factors for suicide. The future psychological autopsy studies may be more focused on interactions between risk factors or risk factor domains, focused on some specific suicide populations of major interest for suicide prevention, or combined psychological autopsy methodology with biological measurements.

IntroductionResponse styles theory postulates that rumination is a central factor in occurrence, severity and maintaining of depression. High neuroticism has been associated with tendency to ruminate.ObjectiveTo evaluate the relationships between rumination, neuroticism and depression in a naturalistic prospective cohort of primary care patients with depressive disorders with life-chart methodology.AimsWe hypothesized, that rumination would correlate with severity and duration of depression and with concurrent anxiety, gender and neuroticism.MethodsIn the Vantaa Primary Care Depression Study, a stratified random sample of 1119 adult patients was screened for depression using the Prime-MD. Depressive and comorbid psychiatric disorders were diagnosed using SCID-I/P and SCID-II. Of the 137 patients with depressive disorders, 82% completed the five-year follow-up with a graphic life chart. Neuroticism was measured with the Eysenck Personality Inventory (EPI-Q). Response styles were investigated at five years using the Response Styles Questionnaire (RSQ-43).ResultsRumination correlated significantly with Hamilton Depression Rating Scale (r = 0.54), Beck Depression Inventory (r = 0.61), Beck Anxiety Inventory (r = 0.50), Beck Hopelessness Scale (r = 0.51) and Neuroticism (r = 0.58). Rumination correlated also with proportion of follow-up time spent depressed (r = 0.38). In multivariate regression, high rumination was significantly predicted by current depressive symptoms and neuroticism, but not by anxiety symptoms or preceding duration of depressive episodes.ConclusionsRumination correlated with current severity of depression, but the association with preceding episode duration remained uncertain. The association between neuroticism and rumination was strong. The findings are consistent with rumination as a state-related phenomenon, which is also strongly intertwined with traits predisposing to depression.Disclosure of interestThe authors have not supplied their declaration of competing interest.

IntroductionIn psychological autopsy studies, at least half of suicides have suffered from depressive or bipolar disorders at time of death. Improving access to care and provision of evidence-based pharmacotherapies can be important preventive measures.ObjectivesTo examine suicide risk and pharmacoepidemiology in mood disorders; evidence for efficacy of pharmacotherapies in mood disorders and in preventing suicidal behaviour in them, and limitations to effectiveness of treatment due to problems of adherence.AimsTo evaluate potentials for suicide prevention in mood disorders by improved access to treatment, improved quality of treatment provision, improved adherence, or by specific pharmacotherapies.MethodsSelective review of literature.ResultsRisk of suicide death and attempts in mood disorders clusters into major depressive and mixed illness episodes, and time spent in them is a major determinant of risk, but direct evidence for preventive effects of effective pharmacotherapies remains limited. Observational and randomized studies indicate lithium treatment to reduce risk of suicide deaths and attempts. Ecological evidence from Europe shows increasing sales of antidepressants to consistently associate with declining regional suicide rates. Forensic chemical studies still find majority suicides negative for antidepressants. Poor adherence is a central problem in treatment provision.ConclusionsPositive impact of increase in pharmacotherapy provision in the last few decades on suicide mortality remains uncertain. Lithium is the pharmacological agent with best evidence for preventive utility, but underused. Providing treatments for those at risk, improving quality and continuity of treatment, and integrating them with psychosocial approaches is likely to be beneficial for suicide prevention.Disclosure of interestThe author has not supplied his declaration of competing interest.
