ABSTRACT
Background and Purpose: People with Spinal Cord Injury face environmental barriers which prevent them in community participation in India. Due to presence of stairs and lack of curb cuts in sidewalks decreases mobility significantly and impairs one’s ability to participate fully. Hence there is a need to assess environmental barriers for people with Spinal cord Injury. Therefore, the purpose of this study is to find out the content validity, concurrent validity, intra-rater and inter-rater reliability of the Craig Hospital Inventory of Environmental factors Short Form (CHIEF – SF) scale and to compare the (CHIEF – SF) scores in Indian population with the International data available.
Materials and Method: A total of 76 subjects with spinal cord injury of more than 1 year duration had participated. Initially Phase I, II, III was applied on 30 subjects and later Phase IV on the total 76 subjects. The study was done in four phases: Phase I: content validation of the Scale; Phase II Intra – rater, Inter – rater reliability of the scale; Phase III: Concurrent Validity with Satisfaction with Life Scale (SWLS) and Craig Handicap Assessment and Reporting Technique (CHART); and Phase IV Normative data and comparison with the international data.
Results: The top 5 barriers were Transportation, Government policies, Discrimination, Natural environment and Help home. For the inter – rater and intra – rater reliability, the intraclass correlational coefficients were 0.861 and 0.844 respectively. The content validity was established by calculating the CVR ratio and was 0.99 for each CHIEF – SF item. For concurrent validity Pearson’s correlational coefficient was used and significant negative correlation was found on both Satisfaction with Life Scale (r = -0.527**, p≤0.01) and CHART scale (r = -0.457*, p≤0.05).
Conclusion: The CHIEF – SF is a valid and reliable scale which can be used in Indian spinal cord injury subjects.
