OBJECTIVE: This study aimed to better characterize the phenomenology and diagnostic stability of youths that report atypical psychotic symptoms. METHOD: In a 2-year longitudinal follow-up study, youths reporting atypical psychotic symptoms (n = 20) were compared with youths with schizophrenia (n = 27) and youths with bipolar disorder with psychotic features (n = 22) on psychotic, dissociative, and general symptomatology, comorbid diagnoses, previous abuse, and overall functioning. Diagnoses were obtained using structured diagnostic interviews (i.e., the Structured Clinical Interview for DSM-IV and the Diagnostic Interview for Children and Adolescents). RESULTS: None of the subjects reporting atypical psychotic symptoms went on to develop a classic psychotic illness by the year 2 follow-up. These subjects had significantly higher rates of abuse and dissociative symptoms, and were significantly more likely to receive a diagnosis of posttraumatic stress disorder (PTSD) or a depressive disorder than youths with schizophrenia or bipolar disorder. CONCLUSION: Our findings suggest that youths with atypical, fleeting, or situationally specific hallucinations are more likely to have a mood or anxiety disorder (such as PTSD) than a current or prodromal psychotic illness.
