Abstract

Purpose:

The PAtient SAtisfaction with Psychotropic (PASAP) scale is a self-completed questionnaire measuring satisfaction with psychotropic medication. The aim of the study was to describe its development in French and its psychometric properties.

Materials and methods:

Scale construction was based on an extensive search of the literature. The item reduction process required semi-structured interviews of psychiatric outpatients (n = 30). The final version of the PASAP is a 9-item, 5-point Likert-type scale, covering the scope of effectiveness and adherence. To assess the psychometric properties of the scale, French patients with an acute manic episode (n = 314) from a large European observational cohort completed the PASAP scale 3 months after psychotropic treatment initiation/change. Internal validity and reliability were assessed using principal component analysis (PCA). Concurrent validity was assessed using comparisons to physician-rated satisfaction with life, illness severity, mood relapse, compliance and side effects.

Results:

Participation rate was 68.4%. PCA was in favour of uni-dimensionality. Cronbach's α coefficient was 0.85 (95%CI 0.83–0.88). All five concurrent measures were significantly associated with the PASAP score.

Conclusion:

The PASAP scale showed good psychometric properties in a large bipolar population and thus seems adequate for evaluating treatment satisfaction. Its short length and good acceptability makes it suitable for clinical research.
