Abstract

Objective of this study to evaluate the content validity and reliability of the modified ICF core set for falls that based on a study of Yen TH et al., in 2014, they linked the fall-related risk factors to the ICF categories that using specified ICF linking rules. This ICF core set was developed as a Thai version of the ICF core set for falls using this study. The original ICF core sets for falls consisted of all of 34 categories. Five experts assessed the content validity of this ICF and remain 31 categories. Results of an item content validity index (I-CVI) were 0.8 and 1, and the scale content validity index (S-CVI) was 8.6. That was very good content validity level. Thirty patients with stroke aged mean 57.6±7.8 years old were evaluated the test –retest reliability of the ICF core set for falls (Thai version) by an assessor, the testing apart one week. The intra-class correlation coefficients: ICC in domains of the body function and body structure were 0.95 (95%CI: 0.92 - 0.97, p-value< 0.0001) and 1.00 (95%CI: 1, p-value< 0.0001), respectively. It was indicated that has very good reliability. The ICC of the activity and participation domains were 0.85 (95%CI: 0.761-0.920, p-value< 0.0001) and the environment factors were 0.79 (95%CI: 0.674-0.884, p-value< 0.0001), that was good reliability. Conclusion, the ICF core set for falls (Thai version) to develop in the study is acceptable. The ICF core set for falls (Thai version) for this model should be re-evaluated for other assessors with a inter rater test.  Moreover, evaluation in other patients and different social contexts may be also considered.
