Assessing aberrant salience in young community help-seekers with early psychosis: The approved Italian version of the Aberrant Salience Inventory

Objectives: Aberrant salience (AS) has a crucial role in the onset of psychosis. The Aberrant Salience Inventory (ASI) is the only self-report instrument specifically developed for the assessment of AS. Aim of this study was to examine the reliability and the validity of the approved Italian version of the ASI in a clinical sample of young help-seekers. Methods: The ASI was completed by 204 individuals, aged 13–35 years. Reliability was assessed examining internal consistency and test-retest reliability. Concordant validity was established with CAARMS (“Comprehensive Assessment of At-Risk Mental States”). Results: The ASI showed high test-retest reliability and excellent internal consistency. The ASI total score had significant positive correlations with CAARMS “Positive Symptoms” subscores. Conclusions: The ASI showed satisfactory psychometric properties and seems to be a suitable instrument for early detection of psychosis in Italian mental health services.
