Abstract
BACKGROUND Incidence of first-episode psychosis (FEP) varies substantially across geographic regions. Phenotypes of subclinical psychosis (SP), such as psychotic-like experiences (PLEs) and schizotypy, present several similarities with psychosis. We aimed to examine whether SP measures varied across different sites and whether this variation was comparable with FEP incidence within the same areas. We further examined contribution of environmental and genetic factors to SP. METHODS We used data from 1497 controls recruited in 16 different sites across 6 countries. Factor scores for several psychopathological dimensions of schizotypy and PLEs were obtained using multidimensional item response theory models. Variation of these scores was assessed using multi-level regression analysis to estimate individual and between-sites variance adjusting for age, sex, education, migrant, employment and relational status, childhood adversity, and cannabis use. In the final model we added local FEP incidence as a second-level variable. Association with genetic liability was examined separately. RESULTS Schizotypy showed a large between-sites variation with up to 15% of variance attributable to site-level characteristics. Adding local FEP incidence to the model considerably reduced the between-sites unexplained schizotypy variance. PLEs did not show as much variation. Overall, SP was associated with younger age, migrant, unmarried, unemployed and less educated individuals, cannabis use, and childhood adversity. Both phenotypes were associated with genetic liability to schizophrenia. CONCLUSIONS Schizotypy showed substantial between-sites variation, being more represented in areas where FEP incidence is higher. This supports the hypothesis that shared contextual factors shape the between-sites variation of psychosis across the spectrum.

Bidirectional associations among school bullying, depressive symptoms and sleep problems in adolescents: A cross-lagged longitudinal approach. J Affect Disord 2022; 298:590-598.

Abstract
BACKGROUND Adolescence is a life stage with a high risk of depression, sleep disorders and school bullying. The aim of this study is to examine the longitudinal relationships between school bullying (bullying victimization and bullying perpetration), depressive symptoms and sleep problems among adolescents and to consider whether the direct pathways vary by gender. METHODS The study included 1687 7th grade students (60.4% boys) recruited from a middle school in southeastern China. We collected self-reports of school bullying, depressive symptoms and sleep problems from 2019 (T1) and 2020 (T2) among adolescents. A series of gender-specified cross-lagged paths in a structural equation model was used for the primary analysis. RESULTS The models revealed evidence for bidirectional associations between school bullying, depressive symptoms and sleep problems. Among girls, higher bullying perpetration at T1 predicted fewer sleep problems and depressive symptoms at T2, while bullying victimization significantly predicted poor quality of sleep and severe depressive symptoms. Furthermore, sleep problems at T1 positively predicted bullying perpetration and victimization at T2 in boys but not in girls. For both boys and girls, severe depressive symptoms significantly predicted more victimization and sleep problems, and sleep problems were positively associated with depressive symptoms. LIMITATIONS The sample is unrepresentative, as it is from only one middle school. CONCLUSIONS Our findings highlight that school bullying, depressive symptoms and sleep problems were interrelated across time and that acknowledging gender differences is important.

The Mediating Effect of Regulatory Emotional Self-Efficacy on the Association between Self-Esteem and School Bullying in Middle School Students: A Cross-Sectional Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2018; 15:ijerph15050991. [PMID: 29762464 PMCID: PMC5982030 DOI: 10.3390/ijerph15050991] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/22/2018] [Revised: 05/02/2018] [Accepted: 05/11/2018] [Indexed: 11/16/2022]
Abstract
School bullying is negatively associated with self-esteem, but psychological mediators of bullying have yet to be clarified. We examined regulatory emotional self-efficacy (RESE) as a possible mediator in the association between self-esteem and school bullying. A cross-sectional study of 995 adolescents was conducted in two middle schools of Xi'an. All of the participants completed the Chinese version of the School Bullying Experience Questionnaire (C-SBEQ), Self-Esteem Scale (SES), and Regulatory Emotional Self-Efficacy Scale (RESE). Descriptive statistics analysis, the bias corrected percentile Bootstrap CI method, and structural equation modelling were used to analyze the data. The results showed that 418 students (42.0%) reported that they were involved in school bullying in the past year. Self-esteem was negatively associated with school bullying (total effect: β = -0.275, 95% CI = -0.381⁻-0.034), and RESE mediated the association between self-esteem and school bullying (indirect effect: β = -0.136, 95% CI = -0.245⁻-0.037). Furthermore, self-esteem had an indirect effect through perceived self-efficacy in managing negative affect, while self-esteem had no indirect effect through self-efficacy in the expression of positive affect. The present study suggests that school authorities and the related education departments should not only focus on improving students' self-esteem, but should also pay more attention to students' RESE, in order to mitigate, and potentially reduce, the occurrence of bullying.

Ann Gen Psychiatry 2017; 16:37. [PMID: 29075310 PMCID: PMC5648489 DOI: 10.1186/s12991-017-0160-4] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2017] [Accepted: 10/11/2017] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Several studies have proven that the experiences of being bullied or bullying others are associated with poor mental health among adolescent youths. Our study aims to investigate the relationship between the experience of the bully/victim and mental health among preadolescents and adolescents. METHODS Subjects were the Japanese fifth and sixth grade elementary school students (preadolescents: mean age = 11.3 years; n = 338) and junior high school students (adolescents: mean age = 13.8 years; n = 486). A self-report questionnaire was administered containing items concerning the experience of being a bully/victim and the Youth Self Report (YSR). RESULTS Four groups relating to the experience of being a bully/victim were formed: "Victim Only," "Bully Only," "Victim and Bully," and "Neither." Approximately 65% of preadolescents and approximately 25% of adolescents engaged in bullying behaviors. Of these, the rate of participants in the "Bully Only" group was low, and that in the "Victim and Bully" group was high. Regarding the relationship between the experience of being a bully/victim and mental health, both preadolescents and adolescents of the "Victim Only" group had significantly higher scores on the YSR's internalizing problems compared with the "Neither" group. Moreover, both preadolescents and adolescents of the "Bully Only" group had significantly higher scores on the YSR's externalizing problems compared with the "Neither" group. Regarding the relationship between the experience of being a bully/victim and suicidal ideation for both preadolescent and adolescent girls, the relative risks of suicidal ideation were significantly higher in the "Victim and Bully" group than in the "Neither" group. CONCLUSIONS Preadolescents indicated a higher rate of bullying behaviors than adolescents. In both preadolescents and adolescents, different effect patterns on mental health were found for the "Victim Only," "Bully Only," and "Victim and Bully" groups. The prevention and intervention methods for mental health should be tailored according to the type of experience associated with being a bully/victim and according to the developmental stages of preadolescence or adolescence.
