This paper presents a questionnaire designed to assess the aspecific treatment efficacy and subjective perceived efficacy of group therapy. A preliminary version of the instrument was administered to a sample of 151 subjects undergoing group therapy. The psychometric properties of the instrument were evaluated by means of the Rasch model, and showed a good score range, good reproducibility and adequate coherence. The hierarchy of difficulty of the items remained stable among the respective categories of sex, age and professional level.
