Development and psychometric testing of the Knowledge, Attitude, and Practice Questionnaire to assess knowledge, attitude, and practices regarding COVID-19 among patients attending COVID screening outpatient department in a tertiary care hospital in North India

BACKGROUND: COVID-19 pandemic has hit the world leading to major disruptions globally. Due to its highly contagious nature and associated mortality, a wide array of emotional and behavioral reactions were seen which indirectly reflected the knowledge, attitudes, and practices (KAP) of individuals. Understanding the KAP of individuals is fundamental when it comes to decreasing future COVID cases. AIM: The study aimed to develop a Knowledge, Attitude, and Practice Questionnaire regarding COVID-19 (COVID-KAPQ) among patients attending screening outpatient department (OPD) in a tertiary care hospital in North India and evaluate its psychometric properties. MATERIALS AND METHODS: The study procedure consisted of step-wise procedure starting with item generation, expert evaluation for categorization of items into domains of KAP and testing for psychometric properties. The items were generated and evaluated by the Delphi method based on 8 experts. Reliability and validity were assessed using data from 200 patients attending COVID screening OPD. Content validity was evaluated using content validity index (CVI); construct validity was examined using exploratory factor analysis and Cronbach's alpha coefficient was computed for internal consistency. RESULTS: The final COVID-KAPQ consisted of three domains and 29 items. Cronbach's alpha coefficient for the entire questionnaire was 0.734, 0.710 for knowledge domain, 0.614 for attitudes domain, and 0.759 for practice domain. CVI ranged from 0.86 to 1. Five factors each for knowledge and attitudes domain and two factors for practice domain were extracted by principal factor analysis and varimax rotation, with a cumulative contribution of 70.19%, 71.54%, and 66.77% variance in KAP domain. CONCLUSIONS: A questionnaire COVID-KAPQ (KAP regarding COVID-19) was developed. Psychometric testing indicated that it had adequate validity and reliability for use in COVID research in the general population. This questionnaire might help the public health researchers to map the level of KAP in the population and plan awareness and prevention strategies accordingly.
