Despite these benefits, sustained participation may be influenced by psychological commitment and contextual determinants. A population-specific measure is therefore needed to assess commitment to Taijiquan exercise among older adults. This study aimed to examine the psychometric properties of the Taijiquan Exercise Commitment Scale for Chinese Elderly (TECS-CE).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      A cross-sectional survey was conducted among 453 older adults aged 60\u201375 years who practiced Taijiquan in Jiaozuo City, Henan Province, China. The participants were divided into an exploratory factor analysis (EFA) sample (\n                      <jats:italic>n<\/jats:italic>\n                      = 203) and a confirmatory factor analysis (CFA) sample (\n                      <jats:italic>n<\/jats:italic>\n                      = 250). Thirty participants completed the scale twice with a 3-week interval to examine test\u2013retest reliability. Content validity was evaluated by five experts using the Index of Item\u2013Objective Congruence (IOC). Construct validity was examined using EFA and CFA, while criterion-related validity was examined through correlations and regression analyses with self-reported Taijiquan exercise behavior.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The final TECS-CE contained 33 items representing two commitment dimensions\u2014Want to Commit and Have to Commit\u2014and six determinants: Satisfaction, Social Constraints, Involvement Alternatives, Personal Investment, Social Support, and Involvement Opportunities. The two commitment dimensions explained 65.005% of the variance, while the six determinants explained 75.378%. CFA indicated acceptable model fit for the reported models; for the structural model, \u03c7\n                      <jats:sup>2<\/jats:sup>\n                      \/df = 1.371, RMSEA = 0.039, RMR = 0.072, AGFI = 0.882, GFI = 0.903, NNFI = 0.984, and CFI = 0.986. Composite reliability ranged from 0.91 to 0.94 and AVE ranged from 0.68 to 0.71. Cronbach\u2019s alpha coefficients ranged from 0.932 to 0.984, and test\u2013retest coefficients ranged from 0.824 to 0.938. The TECS-CE dimensions and determinants were significantly associated with self-reported exercise behavior.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The findings provide evidence that the TECS-CE has acceptable content, construct, criterion-related, and reliability evidence for assessing Taijiquan exercise commitment among the older adults included in this study. Because the study was cross-sectional and used convenience sampling and self-reported exercise behavior, longitudinal and multisite studies are needed to establish predictive validity and broader generalizability.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fpsyg.2026.1889773","type":"journal-article","created":{"date-parts":[[2026,9,16]],"date-time":"2026-09-16T05:33:05Z","timestamp":1789536785000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Validation of Taijiquan (Tai Chi) Exercise Commitment Scale for Chinese Elderly (TECS-CE)"],"prefix":"10.3389","volume":"17","author":[{"given":"Sun","family":"Xianghao","sequence":"first","affiliation":[{"name":"Faculty of Physical Education, Henan Polytechnic University","place":["Jiaozuo, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kritchapol","family":"Arsapakdee","sequence":"additional","affiliation":[{"name":"Department of Health and Sport Science, Faculty of Education, Mahasarakham University","place":["Maha Sarakham, Thailand"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chairat","family":"Choosakul","sequence":"additional","affiliation":[{"name":"Department of Health and Sport Science, Faculty of Education, Mahasarakham University","place":["Maha Sarakham, Thailand"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,9,16]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"3","DOI":"10.1002\/job.1960","article-title":"Cronbach\u2019s alpha reliability: Interval estimation, hypothesis testing, and sample size planning.","volume":"36","author":"Bonett","year":"2015","journal-title":"J.
