Validation of a short adaptation of the Mood and Anxiety Symptoms Questionnaire (MASQ) in adolescents and young adults

AbstractThe Mood and Anxiety Symptoms Questionnaire (MASQ) was developed to measure the symptom-dimensions of the tripartite model of anxiety and depression. A 30-item short adaptation of the MASQ (MASQ-D30) was previously developed and validated in adult psychiatric outpatients. The aim of the present study was to evaluate the validity and reliability of the MASQ-D30 in a sample of adolescents and young adults. Help-seeking adolescents from Australia (N=147; mean age: 17.7 years; 58.8% female) completed the original, 90-item MASQ. Confirmatory Factor Analysis (CFA) was used to evaluate the construct validity (a 3-factor structure) of the original MASQ and the MASQ-D30. Internal consistencies and correlations with other instruments were calculated and compared between versions. CFA showed that the intended 3-factor structure fit adequately to the MASQ-D30 data (CFI=0.95; RMSEA=0.08). Internal consistencies ranged from 0.85 to 0.92 across the scales and patterns of correlations with the Center for Epidemiological Studies-Depression (CES-D) indicated adequate convergent/divergent properties. Importantly, the observed psychometric characteristics were comparable with the original MASQ and alternative short-forms. Results indicated that the MASQ-D30 is a valid and reliable instrument in young people, allowing for quick assessment of the tripartite dimensions of depression and anxiety
