Validation of the Arabic version of the Comprehensive Assessment of At Risk Mental States (CAARMS) in Tunisian adolescents and young adults.

Aim: The study aimed to examine whether the Arabic version of the Comprehensive Assessment of At Risk Mental States (CAARMS) has good construct validity, concurrent validity and reliability.

Methods: Validity was established on a sample of 58 Tunisian adolescents and young adults aged between 16 and 30 years. These subjects were divided into three groups according to the CAARMS scores: ultra-high risk positive subjects (UHR (+) ) (n = 22), ultra-high risk negative subjects (UHR (-) ) (n = 25) and subjects meeting the criteria of a first-episode psychosis (FEP) (n = 11).
