Psychometric Properties of the Community Integration Questionnaire Adjusted for People With Aphasia

Abstract

Dalemans RJ, de Witte LP, Beurskens AJ, van den Heuvel WJ, Wade DT. Psychometric properties of the community integration questionnaire adjusted for people with aphasia. Objectives To describe the feasibility of the Community Integration Questionnaire (CIQ) adjusted for use in people with aphasia and to report its psychometric properties in people with aphasia (internal consistency, factor analysis, test-retest reliability, convergent validity). Design A cross-sectional, interview-based psychometric study. Test-retest reliability was evaluated in 20 people (minimal to severe aphasia) by 2 different interviewers within a 2-week period. Setting Community. Participants In total 490 stroke survivors with (minimal to severe) aphasia were approached, of which 165 (34%) participants returned the answering letter. Participants (N=150) agreed to take part and were interviewed using a structured interview format. Interventions Not applicable. Main Outcome Measures Community Integration Questionnaire (CIQ), Frenchay Aphasia Screening Test, Barthel Index, Dartmouth Coop Functional Health Assessment Charts (COOP)-World Organisation of Family Doctors (WONCA) Charts, Life Satisfaction Questionnaire. Results A total of 150 stroke survivors with aphasia completed the CIQ adjusted for people with aphasia. The CIQ adjusted for people with aphasia was a feasible instrument. Results showed good internal consistency for the CIQ total (standardized Cronbach α=.75), excellent test-retest reliability (intraclass correlation coefficient=.96), moderate correlations with the Barthel Index, the COOP-WONCA, and the Life Satisfaction Questionnaire with regard to construct validity. Significant relations were found with regard to age and aphasia severity. Conclusions The CIQ adjusted for people with aphasia seems to be an adequate instrument to assess participation in people with aphasia.
