Objective:
The objective of this study is to provide a reliable, ICF-based instrument for the compilation of all 9 life domains as defined by the ICF. The "ICF Measure of Participation and ACTivities questionnaire - Screener" (IMPACT-S) is a conceptually and psychometrically profound questionnaire. Due to this fact, it was chosen for translation and subsequent validation.
Methods:
In this multi-centered study, 93 first-time stroke patients were contacted during their inpatient rehabilitation (rehabilitation phases C and D). Postal surveys were then conducted twice 4-6 months after the initial stroke.
Results:
The internal consistency of the individual IMPACT-S domains and the 2 sub-scales can be assessed as satisfactory to very good (0.72-0.94; total score: 0.97). Test-retest reliability was also good to very good.
Conclusion:
The present German version and validation of IMPACT-S covers all the 9 participation domains of the ICF in a comprehensive way and meets all the statistical quality criteria.
