Abstract:Aim: To explore the typology of positive psychotic symptoms related to methamphetamine use (MAP) as such typologies may have potential diagnostic and/or prognostic utility. Methods: Latent class analysis was applied to a self-report questionnaire of 14 positive psychotic symptoms that was administered to 40 MA dependent individuals with a history of psychotic symptoms and no history of a primary psychotic disorder. Results: Three distinct typologies were identified: (1) Paranoid without hallucinations (43%), (2) Paranoid with hallucinations (35%), and (3) First-rank/passivity symptoms (23%). Conclusions: These results provide preliminary empirical evidence that MAP is characterized by different symptom profile typologies. Further investigation is needed to determine whether this heterogeneity in the MAP symptom profile has diagnostic and/or prognostic utility.
