Propiedades psicométricas de una versión española breve de 30 ítems del Cuestionario de Ansiedad y Depresión (MASQE30)

Abstract

In this investigation, we present a short 30-item version of the Mood and Anxiety Symptoms Questionnaire (MASQS30), designed to measure the three dimensions of the tripartite model of anxiety and depression, namely, negative affect (NA), positive affect (PA), and somatic anxiety (SA). This adaptation is from a Dutch version that we administered to a sample of the general canarian population. The proposed goals are to determine the construct validity of the MASQS30 through exploratory and confirmatory factor analysis, as well as its psychometric properties, and convergent, discriminant, and predictive validity with anxiety and depression as assessed through questionnaires. The results confirm adequate construct validity of the MASQS30, as well as internal consistency coefficients ranging between 0.88 and 0.92, and temporal stability, ranging from 0.47 to 0.68. The results corroborate that NA and SA are shared by anxiety and depression, whereas PA is specific to depression. NA and PA corroborate the predictions of the model, but the result of SA does not. The MASQS30 is proposed as an adequate instrument for the dimensional study of depression and anxiety in clinical and community population.
