Psychotic‐like experiences are associated with suicidal feelings and deliberate self‐harm behaviors in adolescents aged 12–15 years

Abstract

Psychotic-like experiences are associated with suicidal feelings and deliberate self-harm behaviors in adolescents aged 12-15 years.Objective: Psychotic disorders are a significant risk factor for suicide, especially among young people. Psychotic-like experiences (PLEs) in the general population may share an etiological background with psychotic disorders. Therefore, the present study examined the association between PLEs and risk of suicide in a community sample of adolescents. Method: Psychotic-like experiences, suicidal feelings, and self-harm behaviors were studied using a self-report questionnaire administered to 5073 Japanese adolescents. Depression and anxiety were evaluated using the 12-item General Health Questionnaire (GHQ). Results: The presence of PLEs was significantly associated with suicidal feelings (OR = 3.1, 95% CI = 2.2-4.5) and deliberate selfharm behaviors (OR = 3.1, 95% CI = 2.0-4.8) after controlling for the effects of age, gender, GHQ-12 score, victimization, and substance use. Suicidal feelings and behaviors were more prevalent in subjects with a greater number of PLEs. Conclusion: Psychotic-like experiences may increase the risk of suicidal problems among adolescents. Significant outcomes• Psychotic-like experiences are associated with suicidal feelings and deliberate self-harm behaviors among adolescents aged 12-15 years.• Suicidal feelings and deliberate self-harm behaviors are more prevalent in subjects with a greater number of psychotic-like experiences. Limitations• This is a cross-sectional study and subjects were recruited from public schools.• A self-report questionnaire was used to assess the psychotic-like experiences, suicidal feelings, and self-harm behaviors.• There was a lack of data about confounding factors, such as individual personality and family circumstances.

Not only Body Weight Perception but also Body Mass Index is Relevant to Suicidal Ideation and Self-Harming Behavior in Japanese Adolescents

“…There was no statistically significant difference between the sexes in this association. The prevalences of current suicidal ideation and acts of self-harm reported in the present study were comparable with those presented in our previous study in a community sample of younger adolescents (Nishida et al 2010).…”

Psychotic experiences and incident suicidal ideation and behaviour: Disentangling the longitudinal associations from connected psychopathology

“…First, the association between PE and suicidal ideation and behaviour has been investigated mostly in cross-sectional studies (Capra et al, 2015;DeVylder et al, 2015b;Jang et al, 2014;Kelleher et al, 2012c;Nishida et al, 2010;Saha et al, 2011;Temmingh et al, 2011), disabling causal inferences. Second, several studies included psychiatric diagnoses in the regression models to control for confounding (Calkins et al, 2014;DeVylder et al, 2015b;Fisher et al, 2013;Koyanagi et al, 2015;LewisFernandez et al, 2009;Olfson et al, 2002;Saha et al, 2011;Sharifi et al, 2015).…”

Psychotic Symptoms in Adolescence Index Risk for Suicidal Behavior

“…In population-based research, 2 recent questionnaire surveys have linked psychotic symptoms and suicidal behavior. Nishida et al 25 found that adolescents who endorsed a questionnaire item about hallucinations were 3 times more likely to also endorse an item related to suicidal ideation. Saha et al, 26 on the other hand, found that individuals who endorsed questionnaire items about delusions were 2 to 4 times more likely to endorse questionnaire items on suicidal behavior.…”
