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.

DESIGN:

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.

SETTING:

Outpatient clinic of the rehabilitation department of an academic hospital.

PARTICIPANTS:

Fifty-seven consecutive persons admitted for multidisciplinary rehabilitation treatment, with various diagnoses, were enrolled in the study; 49 persons completed both assessments.

INTERVENTIONS:

Not applicable.

MAIN OUTCOME MEASURES:

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.
