Adolescents with psychotic experiences report more distress and poorer global functioning than peers. These experiences indicate greater functional disability beyond psychopathology alone.
Area of Science:
- Psychiatry
- Developmental Psychology
- Clinical Psychology
Background:
- Psychotic experiences are common, yet their impact on adolescent functioning and distress is under-researched.
- Understanding these associations is crucial for early intervention and support.
Purpose of the Study:
- To investigate functioning and distress in community-dwelling adolescents reporting psychotic experiences.
- To identify potential mediating factors in the relationship between psychotic experiences and functioning.
Main Methods:
- Assessed 212 school-going adolescents for psychotic experiences, distress, global functioning (Children's Global Assessment Scale), psychopathology, suicidality, trauma, and neurocognition.
- Compared functioning and distress levels between adolescents with and without psychotic experiences.
Main Results:
- 75% of adolescents with psychotic experiences reported distress.
- Adolescents with psychotic experiences exhibited significantly poorer global functioning (mean 68.6 vs. 81.9).
- Poorer functioning persisted even when compared to adolescents with other psychopathology.
Conclusions:
- Adolescents with psychotic experiences face greater functional disability than their peers, irrespective of other diagnoses.
- Clinicians should recognize that psychotic experiences signal potentially higher functional impairment.
- Early identification and intervention are vital for addressing distress and functional deficits.
