Abstract

The prevalence of frequent psychotic-like experiences (PLEs) among surveyed adolescents was 13.5%, 13.2%, and 11.0% over three time points.

  • Five trajectories of PLEs were identified: resistance (74.4%), recovery (9.2%), delayed-dysfunction (6.6%), relapsing/remitting (7.0%), and chronic-dysfunction (2.8%).
  • Adolescents in recovery, delayed-dysfunction, relapsing/remitting, and chronic-dysfunction trajectories were more likely to experience suicidal ideation (SI) compared to those in the resistance group.
  • Depressive symptoms partially mediated the relationship between PLEs trajectories and SI, with specific mediation effects observed for relapsing/remitting, delayed-dysfunction, and chronic-dysfunction trajectories.
  • Timely assessment and targeted interventions for specific PLEs may be necessary to address mental health issues in adolescents.
