Psychotic Experiences and Risk of Suicidal Thoughts and Behaviors: A Systematic Review and Meta-Analysis of Longitudinal Population Studies
Bibliographic record
Abstract
BACKGROUND AND HYPOTHESIS: Since a prior systematic review and meta-analysis reported an association between psychotic experiences (PEs) and suicidal thoughts and behaviors, a large number of new studies have been published on the topic, including several novel studies on the association between PEs and transition from suicidal ideation to attempt. STUDY DESIGN: Two authors independently searched PubMed, Embase, CINAHL, and PsycINFO databases from inception until July 2023, conducted data extraction, and assessed study quality using the Newcastle-Ottawa Quality Assessment Scale. Random-effects models were used to calculate pooled odds ratios (ORs) for the association of PEs and subsequent suicide ideation, suicide attempts, suicide death, and transition from suicidal ideation to attempt, first for the total population, and second stratified by age group. Secondary analyses assessed the mediating role of co-occurring psychopathology. STUDY RESULTS: Twenty studies from 18 different samples (n = 81,861) were identified. Individuals who reported PEs had increased odds of subsequent suicidal ideation (k = 12, OR = 1.90, 95% CI = 1.65-2.19), suicide attempt (k = 13, OR = 2.95, 95% CI = 2.21-3.94), transition from suicidal ideation to suicide attempt (k = 3, OR = 2.83, 95% CI = 1.60-4.99), and suicide death (k = 1, OR = 4.39, 95% CI = 1.63-11.80). This heightened risk was stable across childhood, adolescence, and adulthood. PEs predicted suicide attempts over and above co-occurring psychopathology (k = 8, OR = 2.85, 95% CI = 2.06-3.95). CONCLUSIONS: Individuals reporting PEs are at increased risk of all types of suicidal thoughts and behaviors. In addition, PEs are particularly important risk markers for future suicidal behaviors, including in individuals already reporting suicidal ideation. This risk is in excess of what is explained by co-occurring psychopathology.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
