Background:
Studies on knowledge, attitude, and practice (KAP) can be valuable for public health to help to develop targeted educational programs and assess the effectiveness of intervention programs. The purpose of this study was to develop and examine the validity and reliability of a questionnaire on knowledge, attitude, and practice (KAP) regarding cardiovascular diseases (CVDs), their risk factors, and symptoms among an Iranian general population.
Methods:
This cross-sectional study was conducted on an Iranian population older than 20 years referred to some of Tehran's healthcare centers. An initial 62-item questionnaire was developed, and the face, content, and construct validities were assessed.
Results:
In all, 300 adults with a mean age (SD) of 39.79 (12.1) years participated in this study. Based on the results of the content validity, a questionnaire with 30 essential items was designed. Exploratory factor analysis suggested a four-factor subscale with 29 finalized items (CVD-KAP29), and acceptable goodness of fit indices was demonstrated by confirmatory factor analysis. The Cronbach's alpha and McDonald's ω coefficients were higher than 0.60 for all domains except the nutrition and smoking subscales.
Conclusions:
Results provided evidence of the validity of the CVD-KAP29 for KAP studies for cardiovascular diseases in the general population.
