title: Responsiveness of the Impact on Participation and Autonomy questionnaire.
abstract: OBJECTIVE
  To evaluate the responsiveness of a newly developed generic questionnaire, the Impact on Participation and Autonomy (IPA), which focuses on 2 aspects of participation: perceived participation and the experience of problems.
  
  
  METHODS
  Preliminary study of questionnaire responsiveness compared with transition indices. Participants completed 2 assessments, 3 months apart. To measure change, they completed 9 transition indices at the second assessment. One transition index assessed perceived change in general, the other 8 addressed 1 of the specific problem experience items in the IPA.
  
  
  METHODS
  Outpatient clinic of the rehabilitation department of an academic hospital.
  
  
  METHODS
  Fifty-seven consecutive persons admitted for multidisciplinary rehabilitation treatment, with various diagnoses, were enrolled in the study; 49 persons completed both assessments.
  
  
  METHODS
  Not applicable.
  
  
  METHODS
  Standardized response mean (SRM) and area under the receiver operating characteristic curve (AUC) for participation domain scores and problem scores.
  
  
  RESULTS
  SRMs and AUCs for the participation domains ranged from 0.1 to 1.3 and from 50% to 92%, respectively. The SRMs of the items on the experience of problems ranged from 0.4 to 1.5, whereas their AUCs ranged from 56% to 74%.
  
  
  CONCLUSIONS
  The IPA detected within-person improvement over time, but its responsiveness must be confirmed in a larger study sample.
