Factor structure of Participation Behavioural Questionnaire (PBQ) in patients with hand injuries

Abstract

Background Participation is considered a critical outcome of successful rehabilitation and should be evaluated. Objective We aimed to evaluate the structural validity of the Participation Behaviour Questionnaire (PBQ) in people with hand injuries. Methodology The PBQ contains 30 items that measure participation as conceptualized in the ICF. PBQ was developed with Rasch analysis to measure participation in hand injured. A sample of 404 patients with hand injuries and a mean age of 37 (16.0) participated and was randomly split for exploratory and confirmatory factor analysis (EFA/CFA). Results Both EFA and CFA confirmed a four factor-solution. These factors were named: Social Participation and Interpersonal Relationships, Autonomy and Role, Subjective Satisfaction with Participation, Recreational, Sport, and Leisure Time. The value of Cronbach's alpha was 0.96 for the total scale and >0.85 for each subscale. Conclusions The structural validity of the PBQ was confirmed using both EFA and CFA. The PBQ measures four dimensions of participation.
