Abstract
INTRODUCTION: The Craig Hospital Inventory of Environmental Factors instrument (CHIEF) is one of the few tools to assess the environmental barriers. The purpose of this study was to translate long and short CHIEF into Hindi language, and to determine its validity and reliability. DESIGN AND SETTING: The study design was observational case series with repeated measures. It was carried out at Indian Spinal Injuries Centre New Delhi, a specialized center for rehabilitation for spinal cord injury. METHODS: The CHIEF instrument was translated from English to Hindi based on the Beaton guidelines for the cross-cultural adaptation of health status measures. The Hindi version of the CHIEF instrument was then administered on a convenience sample of 30 spinal cord injured subjects. Its content validity, internal consistency, test-rest reliability (intraclass correlation coefficient [ICC] 2,1), standard error of measurement (SEM), and minimum detectable change (MDC) were determined for both the longer and shorter version. RESULTS: The mean +/- SD of total of Hindi-CHIEF instrument, longer version was 1.44 +/- 0.82 and total score of the shorter version was 1.07 +/- 0.66. The content validity determined by the content validity ratio was found to be 1 for all the items except item number 5, 11, and 12. The content validity index was 0.97 for the longer version and for the shorter version it was 0.98. Internal consistency, Cronbach's alpha value was found to be 0.92 and test-retest value (ICC 2,1) was 0.80 (P < 0.001). The MDC was found to be 0.99 and SEM was 0.36 for the longer version. The Cronbach's alpha was 0.731, ICC 2,1 was 0.63 (P < 0.001), SEM was 0.24, and MDC was 0.66 for the shorter version. CONCLUSION: The Hindi translated version of the CHIEF scale has acceptable content validity and reliability. It can be used to assess environmental barriers perceived by spinal cord injury patients.
