Introduction: 'Let's Talk About Children' is a brief family focused intervention developed to improve mental health outcomes of children of parents with mental illness (COPMI). This study aims to assess the efficacy of LTC in improving mental health of children of parents with schizophrenia or bipolar disorder in China. Methods: The planned study is a multicentre parallel group randomized wait-list controlled trial. A total of 400 eligible families with children aged 8 to 18 years will be recruited, 200 each for families with parental schizophrenia or bipolar disorder. The intervention group will receive Let's Talk About Children delivered by a trained therapist, while the control group will receive treatment as usual. The primary outcomes are child mental health measured by the strengths and difficulties questionnaire and parent–child communication measured using the parent-adolescent communication scale. Parental mental health and family functioning are secondary outcomes. This study also plans to explore mediating factors for the effect of Let's Talk About Children on child mental health, as well as conduct a cost-effectiveness analysis on using Let's Talk About Children in China. Conclusion: The present study will provide evidence for the efficacy of Let's Talk About Children in families with parental schizophrenia and bipolar disorder in China. In addition, it will evaluate potential mechanisms of action and cost-effectiveness of Let's Talk About Children, providing a basis for future implementation. Trial registration: ChiCTR2300073904.

Schizophrenia (SZ) and intellectual disability (ID) are both included in the continuum of neurodevelopmental disorders (NDDs). DNA methylation is known to be important in the occurrence of NDDs. The family study is conducive to eliminate the effects of relative epigenetic backgrounds, and to screen for differentially methylated positions (DMPs) and regions (DMRs) that are truly associated with NDDs. Four monozygotic twin families were recruited, and both twin individuals suffered from NDDs (either SZ, ID, or SZ plus ID). Genome-wide methylation analysis was performed in all samples and each family. DMPs and DMRs between NDD patients and unaffected individuals were identified. Functional and pathway enrichment analyses were performed on the annotated genes. Two significant DMPs annotated to CYP2E1 were found in all samples. In Family One, 1476 DMPs mapped to 880 genes, and 162 DMRs overlapping with 153 unique genes were recognised. Our results suggested that the altered methylation levels of FYN, STAT3, RAC1, and NR4A2 were associated with the development of SZ and ID. Neurodevelopment and the immune system may participate in the occurrence of SZ and ID. Our findings suggested that DNA methylation participated in the development of NDDs by affecting neurodevelopment and the immune system. [ABSTRACT FROM AUTHOR]

Objective: Nonadherence to antipsychotic medication is a major health concern. Identification of risk factors associated with nonadherence is a useful initial step toward designing an effective intervention. This study compared the characteristics of medication-adherent and -nonadherent outpatients with schizophrenia in a Chinese community setting.Methods: In a naturalistic, multicenter, and cross-sectional design, 601 outpatients with schizophrenia served by the National Continuing Management and Intervention Program for Psychoses (the "686 program") were surveyed from June 2013 to January 2014 in four Chinese cities. On the basis of self-reported behavior, the patients were divided into medication-adherent and -nonadherent groups. Logistic regression analyses were performed to identify potential risk factors associated with nonadherence.Results: The analyses included 554 patients, 20% of whom were considered to be nonadherent. Compared with the adherent group, the nonadherent group had a longer period of untreated psychosis (odds ratio [OR]=1.09), lower body mass index (OR=.94), higher rate of rural residency (OR=2.01), and lower monthly household income per capita (OR=.94/100 renminbi) (p<.05 by hierarchical analysis). Other characteristics (age, gender, occupation, education, marital status, living with family, age at initial presentation of symptoms, duration of illness, and type of antipsychotic medication) did not differ significantly between the groups.Conclusions: Medication-adherent and -nonadherent groups differed significantly in some social and treatment characteristics. These findings may be useful in informing the development of strategies for reducing medication nonadherence. [ABSTRACT FROM AUTHOR]
