Abstract:
Introduction: Malaysian adults consume excessive amounts of salt daily, which
could lead to hypertension. Understanding knowledge, attitudes, and practices
(KAP) surrounding salt intake is crucial for designing effective interventions to
reduce excessive consumption and its associated health risks. Therefore, this study
aimed to adapt an existing salt intake-related KAP questionnaire that was previously
employed in a local population-based survey and to validate and test its reliability.
Methods: This cross-sectional study comprised two phases: (1) adaptation, content
validation (CV), and face validation (FV); (2) pilot testing and reliability testing. CV
and FV involved a total of seven experts and ten Malaysian adults from the Klang
Valley, respectively. Pilot testing involved 139 Malaysian adults to determine the
questionnaire’s reliability. Content validity index (CVI) and Face validity index
(FVI) values were calculated to analyse CV and FV. Reliability of each domain was
analysed by obtaining Cronbach’s alpha (α) values. Results: A self-administered
questionnaire comprising six items each for knowledge, attitude, and practice was
developed. The questionnaire demonstrated acceptable item-level CVI (I-CVI) and
item-level FVI (I-FVI) values of at least 0.83, indicating that the items were relevant,
clear, non-ambiguous, and simple. Reliability test showed acceptable α values
of at least 0.70 for each domain, suggesting that the questionnaire was reliable.
Conclusion: This tool could be considered valid and reliable for assessing the level
of KAP towards salt intake among adults in Malaysia.
