title: Inter-rater and intra-rater reliability of the Bahasa Melayu version of Rose Angina Questionnaire.
abstract: The objective of the study is to translate the Rose Questionnaire (RQ) into a Bahasa Melayu version and adapt it cross-culturally, and to measure its inter-rater and intrarater reliability. This cross sectional study was conducted in the respondents' homes or workplaces in Kelantan, Malaysia. One hundred respondents aged 30 and above with different socio-demographic status were interviewed for face validity. For each inter-rater and intra-rater reliability, a sample of 150 respondents was interviewed. Inter-rater and intra-rater reliabilities were assessed by Cohen's kappa. The overall inter-rater agreements by the five pair of interviewers at point one and two were 0.86, and intrarater reliability by the five interviewers on the seven-item questionnaire at poinone and two was 0.88, as measured by kappa coefficient. The translated Malay version of RQ demonstrated an almost perfect inter-rater and intra-rater reliability and further validation such as sensitivity and specificity analysis of this translated questionnaire is highly recommended.
