DEVELOPMENT AND PSYCHOMETRIC TESTING OF KNOWLEDGE, ATTITUDE, AND PRACTICE ON COVID-19 OUTBREAK QUESTIONNAIRE (KAPCovQ) FOR GENERAL COMMUNITY

Objective: To develop a valid and reliable questionnaire about knowledge, attitudes, and practices towards Covid-19 (KAPCovQ) in the general community based on psychometric properties. Methods: This study consisted of item development, scale development, and scale evaluation. Item development was based on literature review and content validity by experts. Scale development was conducted by pre-testing ten respondents. Scale evaluation was assessed using 375 respondents. Scale evaluation included construct validity with exploratory factor analysis (EFA) followed by confirmatory factor analysis (CFA) and reliability test with Cronbach’s α, composite reliability, and test-retest reliability. Results: The final KAPCovQ consisted of 3 domains with 31 items. Twelve items of the knowledge domain met the acceptable range for item analysis. Three factors of attitude domain and one factor of practice domain showed that 59.13% and 57.97% of the total variance respectively were identified in EFA. The result of the CFA for both attitude and practices domain indicated acceptable fit indices for the proposed model. The CFA model fit indices of attitude domain were χ2/df 2.05, p-value 0.01, GFI 0.92, RMSEA 0.07, TLI 0.90, CFI 0.92, and PNFI 0.64 and practices domain were χ2/df 1.18, p-value 0.28, GFI 0.98, RMSEA 0.03, TLI 0.98, CFI 0.99, and PNFI 0.54. Knowledge and all factors in the attitude and practice domain had an acceptable range in internal consistency reliability and test-retest reliability. Conclusion: The finding of this study demonstrated that KAPCovQ is valid and reliable for measuring the KAP on Covid-19 in the general community
