Abstract
Session presented on: Tuesday, July 23, 2013:
Purpose: People with cardiovascular risk factors can prevent the progression of the disease and promote their health status by performing appropriate health behaviors. The purpose of this study was to develop a cardiac health behavior scale and validate the psychometrics of this scale for individuals with cardiovascular risks.
Methods: Based on the literature review, a Cardiac Health Behavior Scale (CHB22), a 22-item with a 4-point response format, was developed to represent an individual's likelihood of engaging in five key dimensions of cardiac health behaviors: health responsibility, exercise, diet habits (eating habits and food choice), stress management, and smoking cessation. The frequency of each behavior with higher scores indicates more frequent performance of health behaviors. Validity and reliability of the scale was assessed using data on 298 subjects from two different research projects in Korea investigating cardiovascular risks. Confirmatory factor analysis (CFA) was used to establish the construct validity using AMOS 20.0. We verified correlations between the CHB22 with self-efficacy included in the Song & Lee (2001) Motivation Scale for Health Behavior to assess the convergent validity. Reliability was assessed using Cronbach's alpha coefficients.
Results: The construct validity and reliability of the CHB22 was acceptable using the five main factors identified. The model was a good fit for the data: ?2/DF=344/193, GFI=.91, CFI=.91 and RMSEA=.05. Main factors of the CHB22 moderately correlated with self-efficacy (r=.42-.50, p<.001) except for diet habits. The CHB22 demonstrated high overall reliability (Cronbach's alpha = 0.82), and also acceptable reliability for each factor .56 to .76.
Conclusion: The CHB22 has strong psychometric qualities and should be useful for assessing cardiac health behaviors among adults with cardiovascular risks. We recommend that the diet factor of the CHB22 needs to be revised to assess diet habits among this population more exactly.
