Development and Validation of a Questionnaire Assessing Knowledge, Attitude, and Practices about Obesity among Obese Individuals

AIM: The objective of this study was to develop and validate a knowledge, attitude, and practice (KAP) questionnaire about obesity among obese individuals. MATERIALS AND METHODS: The questionnaire was developed following a standardized protocol that consisted of literature review, focused group discussions, and expert opinion. A cross-sectional survey on 100 obese individuals was carried out to validate the tool. Exploratory factor analysis was performed, using principal component with varimax rotation, to establish the construct validity of the questionnaire. Internal consistency of the questionnaire was tested using Cronbach's α coefficient. RESULTS: KAP questionnaire with 42 items categorized under three domains knowledge, attitude, and practices was developed. The KAP sections have 14, 15, and 13 items, respectively. Independent Cronbach's α for KAP domains were 0.75, 0.75, and 0.63, respectively, indicating good internal consistency. CONCLUSION: The developed questionnaire will be helpful in achieving better understanding of the patients' KAP about obesity. It has satisfactory validity and good internal consistency.
