Abstract

The Quality of Life, Enjoyment and Satisfaction Questionnaire (Q-LES-Q) is increasingly used in psychiatry because it gives emphasis to the subjective perspective of patients on physical, psychological and social domains. This paper reports on the validation of the Italian version of the Q-LES-Q in a large multicenter study (EQUIP) conducted at five Italian sites on outpatients in treatment for anxiety disorders. Study participants underwent a broad assessment of psychopathology including the MINI-International Neuropsychiatric Interview, the Symptom Checklist (SCL-90) and the Clinical Global Impression (CGI). Cronbach's alpha was used to determine the internal consistency of the Q-LES-Q areas and Pearson's r was used to analyze the correlation between the areas of Q-LES-Q and those of the other instruments. The internal consistency of the Q-LES-Q proved to be substantial (>0.80 in each of the areas) as well as the test-retest reliability. The convergent validity of the Q-LES-Q vs. the Work and Social Adjustment Scale was examined. High correlations were found between scales measuring similar constructs in the two instruments and lower correlation between scales measuring different constructs. In conclusion, the Italian version of the Q-LES-Q proved to be as valid and reliable as the original English version.
