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.
