“…Psychotic experiences are far more common in the population than psychotic disorder (Cullen et al, 2014;Devylder et al, 2013;Laurens et al, 2012;Lin et al, 2011;Saha et al, 2011a). Among young people, these experiences most commonly occur in the form of auditory hallucinations, which may be frankly psychotic in nature or, more commonly, attenuated (that is, hallucinatory experiences with intact reality testing) (Kelleher et al, 2011).…”

“…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). However, it is conceptually impossible to examine a confounder in the association between PE and suicidal behaviour when that confounder, for example depression, is fundamentally associated with the outcome (Miller and Chapman, 2001).…”

Psychotic experiences and incident suicidal ideation and behaviour 2 ABSTRACT This study examines the longitudinal associations between psychotic experiences (PE) and incident suicidal ideation and behaviour in the general population, and to what degree the association may be confounded by nonpsychotic psychopathology. Data from three prospective, general population cohorts were combined into one dataset (n=15837) and analysed using logistic regression, controlling for continuous measures of depression, anxiety and mania symptoms. Analyses were conducted in the entire sample, and in subsamples stratified by presence or absence of mental disorders. The presence of PE at baseline increased the risk of incident suicidal ideation and behaviour. However, adjustment for dimensional measures of psychopathology reduced effect sizes, although PE remained significantly associated with suicide attempts. Further examination of the associations revealed that PE were only associated with suicide attempts in individuals with at least one mental disorder.Similarly, in individuals without mental disorders, the risk of suicidal ideation increased as PE co-occurred with more symptom domains. The results of this study confirm that individuals with PE are at increased risk of suicidal ideation and behaviour. However, these associations are not specific, but reflect the increased risk of suicidal ideation in individuals with subthreshold multidimensional psychopathology and suicide attempts in individuals with co-occurring mental disorders.

“…Recent cross-sectional research has demonstrated a strong association between psychotic experiences and suicidality (7,10,19) and two longitudinal reports have demonstrated high risk of suicide attempts in population samples who report psychotic experiences (9,20). We wished to investigate whether psychotic experiences would act as a risk marker for the persistence of suicidal ideation in a longitudinal study of Swedish adolescents followed to early adulthood, something that has not been addressed in the literature to date.…”

Psychotic experiences are far more prevalent in the population than psychotic disorders and are associated with a wide range of depressive, anxiety and behavioral disorders, as well as increased risk for psychotic disorder. Recently, psychotic experiences have been highlighted as a potentially valuable clinical marker of risk for suicidal behavior. There have been few studies to date, however, to assess psychotic experiences as a predictor of suicidality over time. We wished to assess whether young persons with suicidal ideation at baseline assessment who reported psychotic experiences were at higher risk for persistence of suicidal ideation at follow-up than young persons who also reported suicidal ideation at baseline but who did not report co-occurring psychotic experiences. A total of 2,263 adolescents were assessed at age 13 to 14 years for psychotic experiences, suicidal ideation and internalizing and externalizing psychopathology. Participants were re-assessed at ages 16 to 17 years and 19 to 20 years. Among 13-to 14-year olds with suicidal ideation, co-occurring psychotic experiences did not predict an increased odds of persistence of suicidal ideation to age 16 to 17 years (OR50.94, 95% CI: 0.19-4.78). Among 16-to 17-year olds with suicidal ideation, however, co-occurring psychotic experiences predicted a 6-fold increased odds of persistence of suicidal ideation to age 19 to 20 years (OR55.53, 95% CI: 1.33-23.00). Psychotic experiences are an important but under-recognized marker of risk for persistence of suicidal ideation, in particular from mid-adolescence. An increased emphasis on the clinical assessment of psychotic experiences in mental health services should be a priority.
