摘要

Background

Establishing regular exercise habits during adolescence is essential for fostering lifelong physical activity participation. Despite its importance, reliable and culturally appropriate tools to assess exercise habits among Chinese adolescents remain limited. This study aimed to develop and validate the adolescent exercise habit scale (AEHS), a psychometrically sound instrument for assessing self-reported exercise habits in this population.

Methods

Grounded in a multidimensional conceptual framework, the initial 33-item pool was generated based on literature review and expert consultation. A total of 1346 students aged 12 to 18 completed the preliminary version of the scale. The sample was randomly divided for item analysis, exploratory factor analysis (EFA), and confirmatory factor analysis (CFA). Reliability was assessed using Cronbach’s α, while validity was examined through construct validity, convergent validity, and preliminary criterion-related evidence. In addition, we employed a percentile-based method to classify adolescents' exercise habit levels according to their scale scores.

Results

The final AEHS consisted of 12 items loading on three dimensions: exercise consistency, self-motivation, and integration of exercise into daily life. The AEHS showed acceptable internal consistency, content validity, convergent validity and criterion-related validity (Cronbach’s α ranged from 0.705 to 0.855, CVI values ranged from 0.79 to 0.87, AVE values ranged from 0.378 to 0.603, and correlation coefficients ranged from 0.564 to 0.659). The AEHS also enables the classification of adolescents' exercise habits into low, moderate, and high levels based on their total scores.

Conclusions

Overall, the AEHS appears to be a valid and reliable tool for evaluating adolescent exercise habits in Chinese contexts and may contribute to more targeted interventions in physical activity promotion.
