Impact on Participation and Autonomy (IPA): Psychometric evaluation of the Persian version to use for persons with stroke

Abstract

The aim of this study was to evaluate the psychometric properties of the Persian version of the Impact on Participation and Autonomy questionnaire (IPA-P) to use for persons with stroke. A total of 102 persons diagnosed with first-ever stroke participated in this cross-sectional study. The psychometric properties were evaluated using a Rasch rating scale model. The results showed that IPA-P could not measure perceived participation as one unidimensional construct according to the criteria, but supported two different but related constructs. Performance-based participation consisted of 19 items including three IPA domains: autonomy indoors, family role, and autonomy outdoors. Social-based participation consisted of seven items from the social relations domain. The results provided evidence of internal scale validity, person response validity, and sensitivity for each of the two constructs of IPA-P. In conclusion, the results supported the psychometric properties of two constructs of perceived participation in the Persian sample tested. However further evaluation of psychometric properties of the IPA is needed in a variety of diagnoses and in other cultural backgrounds.

The outcome measures for loss of functionality in the activities of daily living of adults after stroke: a systematic review

“…30 The majority of the participants were in their mid to late 60s, with mean ages ranging from 53 ± 13 years 56 to 77.8 ± 7.5 years. 35 The most represented languages were Chinese 27,28,36,[40][41][42][43]53,62 and English, 31,34,45,46,55 with 10 and 5 validated tools, respectively. The measurement properties for each version of each tool are summarized in Table 2.…”

Are the Domains Considered by ICF Comprehensive Enough to Conceptualize Participation in the Patient with Hand Injuries?

“…Some authors are argued that participation could not be measured as a unidimensional construct: performance-and social-based participation. 21 By reviewing outcome measures, the authors again extracted some aspects of inner participation, such as compensatory behavior, autonomy, and physical conditions that can be all considered as satisfaction in participation.…”

Responsiveness of two participation measures in an outpatient rehabilitation setting

“…This makes the IPA a very relevant instrument for occupational therapy (1,20). The IPA has already been validated in different languages (18)(19)(20)(21)(22)(23)(24) and its validity and reliability are good (6). Moderate responsiveness of the IPA has also been shown (25).…”
