Personality traits and self-harm behaviors among Chinese children and adolescents: The mediating effect of psychological resilience

BACKGROUND Previous studies have shown that personality traits are associated with self-harm(SH)in adolescents.However,the role of resilience in this association remains unclear.Our research aims to explore the hypothesized mediation effect of resilience in the relationship between personality traits and SH in Chinese children and adolescents.AIM To evaluate resilience as a mediator of the association between personality traits and SH.METHODS A population-based cross-sectional survey involving 4471 children and adolescents in Yunnan province in southwestern China was carried out.Relevant data were collected by self-reporting questionnaires.Univariate and multivariate logistic regression models were employed to identify associated factors of SH.A path model was used to assess the mediation effect of resilience with respect to personality traits and SH association.RESULTS Among the 4471 subjects,1795 reported SH,with a prevalence of 40.1%(95%CI:34.4%-46.0%).All dimensions of personality traits were significantly associated with SH prevalence.Resilience significantly mediated the associations between three dimensions of personality(extroversion,neuroticism,psychoticism)and SH,accounting for 21.5%,4.53%,and 9.65%,respectively,of the total associations.Among all dimensions of resilience,only emotional regulation played a significant mediation role.CONCLUSION The results of the study suggest that improving emotion regulation ability might be effective in preventing personality-associated SH among Chinese children and adolescents.

Childhood maltreatment and suicide ideation: A possible mediation of social support

BACKGROUND Existing literature suggests a positive link between childhood maltreatment(CM)and suicide ideation(SI).Nevertheless,whether social support significantly mediates this association remains unknown.AIM To investigate whether social support significantly mediates the association between CM and SI.METHODS In this cross-sectional study of 4732 adolescents from southwest China,we intended to discuss the association between CM and multiple types of SI.In addition,the mediation of major types of social support in this association was also investigated.A self-administrated questionnaire was used to collect the data.A series of multivariate logistic regression models were employed to estimate the association between different types of CM,social support,and SI.The possible mediation of social support in the association between CM and SI was assessed using the path model.RESULTS Based on the cutoffs for subscales of Childhood Trauma Questionnaire,928(19.61%),1269(26.82%),595(12.57%),2337(49.39%),and 3067(64.81%)respondents reported physical abuse,emotional abuse,sexual abuse,physical neglect,and emotional neglect,respectively.Among all the social sources,parental support presented as a significant mediator in the association between emotional maltreatment,both abuse and neglect,and all three types of SI:1-wk,1-year,and lifetime.Parental social support mediated 5.31%and 29.23%,4.80%and 24.50%,and 7.04%and 44.42%of the overall emotional abuse-SI and emotional neglect-SI associations,respectively.CONCLUSION Our findings suggest that improving parental social support might be effective in preventing suicidal risk related to childhood emotional maltreatment in adolescents.
