ABSTRACT
BACKGROUND:
Measuring health-related diet and exercise self-efficacy is an important first step in improving healthy behaviors and health outcomes. However, we did not find a self-efficacy measurement in Chinese that is specifically targeted at diet and exercise self-efficacy among healthy adults.AIM:
The present study aimed to translate the Health-Related Diet and Exercise Self-Efficacy Scale -simplified version into Mandarin Chinese (HRDESES) and evaluate its reliability and validity in Chinese healthy adults.METHODS:
The HRDESES was translated and adapted to the Chinese context, with a good content validity of 0.86 among seven experts. The survey was then carried out in 216 adults in Hunan, China. Testing of the reliability included internal consistency reliability and test-retest reliability, while validity included content validity, construct validity, and criterion validity.RESULTS:
The Cronbach's α of the HRDESES was 0.87 for the total scale, 0.86 for the diet subscale and 0.91 for the exercise subscale; the McDonald's ω of the HRDESES-SC was 0.85 for the total scale, 0.86 for the diet subscale and 0.91 for the exercise subscale, all demonstrating good internal consistency. The test-retest reliability was 0.88 for the total scale, 0.81 for the diet subscale and 0.82 for the exercise subscale, demonstrating good test-retest reliability. For construct validity, the scale effectively distinguished subjects by age, gender, education, occupation, marital status, and family income, showing good discriminant validity. The confirmatory factor analysis (CFA) supported a two-factor structure of the scale diet and exercise subscale. It was demonstrated that the HRDESES was highly associated with the General Self-Efficacy Scale and its two subscales, with correlation coefficients ranging from 0.83 to 0.86 (p < 0.05), showing high criterion validity.CONCLUSION:
The HRDESES had good reliability and validity and could be used as a simple and effective tool for assessing the health-related diet and exercise self-efficacy in Chinese healthy adults.Palabras clave
