Abstract
Purpose This research sought to translate and culturally adapt the content of the original Physical Activity Recall Assessment for People with Spinal Cord Injury (PARA-SCI) into the Thai language and to assess its inter- and intra-rater reliability. Methods This study was divided into two parts; (i) translation and cross-cultural adaptation, using a six-step guideline-based translation-validation process and (ii) reliability assessment of the translated survey tool using intraclass correlation coefficients (ICCs), Bland-Altman plots and one-way ANOVA analyses. Results The Thai-PARA-SCI was successfully developed. The results revealed an excellent inter-rater reliability (ICC = 0.99, 95% CI range from 0.959-0.999) and the Bland-Altman plots showed little difference in times spent engaged physical activity. Intra-rater reliability results were affected inadvertently by testing across an unusual period, demonstrating poor to moderate scores (ICC ranged from 0.05-0.69, 95% CI ranged from -0.067-0.830) with the Bland-Altman plots showing very different ranges of time spent on physical activity. Conclusion This study achieved its aims of culturally and systematically translating the English PARA-SCI interview script into the Thai version with excellent scores for inter-rater reliability and was proven to be understandable by prospective users (Thai-PT) and participants (Thai-SCI).
