Child and Adolescent Mindfulness Measure (CAMM): Study of the Psychometric Properties of the Portuguese Version

The aim of this study is to present the Portuguese version of the Child and Adolescent Mindfulness Measure (CAMM) and examine its factorial structure and psychometric properties in a sample of 410 adolescents with mean age of 15.18 years. Results show that the CAMM is a single-factor self-report measure, presenting an adequate internal consistency (a = .80; CR = .85) and test-retest reliability (r = .46). Negative correlations were found with measures of depression, anxiety and psychological inflexibility. On the other hand, positive correlations were found with measures of social comparison. Even when psychological inflexibility effects (process associated with mindfulness) were controlled, the correlations were still significant. Overall, findings suggest that the CAMM is a reliable and valid measure for the assessment of mindfulness skills in children and adolescents.
