| Summary: | The use of questionnaire as a tool to measure public perception on their risk of developing disease
has been widely used by many researchers. However, in Malaysia, there is no validated questionnaire
developed for such purpose yet. This study aim to develop and validate the questionnaire on risk perception of
developing five most common non-communicable diseases (NCDs) in Malaysia. A cross sectional study was
carried out among staff and clients of Kuala Rompin Health Clinic, Pahang aged 18 years and above from
different ethnicities and age groups. This study was divided into 4 phases: i) developing the questionnaire
involving related specialists and pre testing, ii) improving and editing the questionnaire and redistribution to
130 respondents for the pilot study, iii) factor analysis and confirmatory factor analysis, and iv) internal
consistency reliability testing of the questionnaire . Factor analysis performed showed that factors loading
values are all more than 0.4 and items in each domain were correlated with items in the same domain, but not
with items in the other domain; findings which support the convergence and discriminant validity of the
questionnaire. Confirmatory factor analysis came up with one five factors best fit model. Internal consistency
reliability analysis on health related behavior, special practices, information seeking and perceived probability
of diseases have good Cronbach α values of between 0.5 to 0.8, whereas intra-class correlation (ICC) for the
perceived severity has a value of between 0.1 to 0.2. Thus, the questionnaire is successfully validated and
considered as a useful tool to be used in measuring public perception on their risk of developing NCDs in
Malaysia. However, improvement will still be necessary from time to time to ensure its relevance especially if
it is to be used by different populations or countries of different background in Malaysia, taking into account
the new changes in disease pattern.
