Key result
The Mandarin Chinese version of the Tai Chi Exercise Self-Efficacy scale demonstrated high internal consistency (Cronbach’s α 0.97) and good test-retest reliability (ICC 0.86, p<0.01).
Why the study?
Tai Chi is effective for individuals with coronary heart disease or risk factors, but an accurate and systematic assessment of Mandarin-speaking adults' self-efficacy in maintaining Tai Chi exercise was lacking.
Cross-Sectional (n=140)
Effect estimate: Cronbach’s α 0.97, ICC 0.86
p-value: p=< 0.01
The Mandarin Chinese version of the Tai Chi Exercise Self-Efficacy scale is a valid and reliable instrument for assessing exercise self-efficacy in patients with coronary heart disease or risk factors.
May aid self-efficacy assessment in Mandarin-speaking Tai Chi users; leaves open outcome validation.
Tai Chi is an effective exercise option for individuals with coronary heart disease or its associated risk factors. An accurate and systematic assessment of a Mandarin-speaking adults’ self-efficacy in maintaining Tai Chi exercise is lacking. Mandarin Chinese has the most speakers worldwide. This study aimed to translate the Tai Chi Exercise Self-Efficacy scale and examine its psychometric properties. The 14-item Tai Chi Exercise Self-Efficacy scale was translated from English into Mandarin Chinese using a forward-translation, back-translation, committee approach, and pre-test procedure. Participants with coronary heart disease or risk factors (n = 140) enrolled in a cross-sectional study for scale validation. Confirmatory factor analysis indicated a good fit of the two-factor structure (Tai Chi exercise self-efficacy barriers and performance) to this sample. The translated scale demonstrated high internal consistency, with a Cronbach’s α value of 0.97, and good test-retest reliability, with an intra-class correlation coefficient of 0.86 (p < 0.01). Participants with prior Tai Chi experience reported significantly higher scores than those without (p < 0.001), supporting known-group validity. A significant correlation was observed between the translated scale and total exercise per week (r = 0.37, p < 0.01), providing evidence of concurrent validity. The Mandarin Chinese version of the Tai Chi Exercise Self-Efficacy scale is a valid and reliable scale for Chinese adults with coronary heart disease or risk factors.

Liu et al. (2021) conducted a cross-sectional in Coronary heart disease or risk factors (n=140). Tai Chi Exercise Self-Efficacy scale (Mandarin Chinese version) was evaluated on Scale validation (internal consistency and test-retest reliability) (Cronbach’s α 0.97, ICC 0.86, p=< 0.01). The Mandarin Chinese version of the Tai Chi Exercise Self-Efficacy scale demonstrated high internal consistency (Cronbach’s α 0.97) and good test-retest reliability (ICC 0.86, p<0.01).
