It is becoming increasingly important to determine whether structural models of measures of sport and activity behavior developed in North America are invarant across different populations. This study assessed (a) the cross-cultural validity of the Task and Ego Orientation in Sport Questionnaire (TEOSQ) using male college students across the United States (n = 309), Thailand (n = 312), and Taiwan (n = 307); and (b) the factorial equivalence and structured latent mean differences of the TEOSQ in these samples. Using a confirmatory factor analytic procedure, the initial test of the hypothesized two-factor structure representing task and ego orientation yielded a good fit for each sample. The factor structure was further shown to be metric invariant across the three countries. Furthermore, tests of latent means showed significant differences between groups. The United States sample exhibited the highest levels of task and ego orientation, followed by the Taiwan and Thailand samples, respectively.

The primary objective of this study was to provide preliminary evaluation of the feasibility, safety, and efficacy of a newly developed Tai Chi-based exercise program for older adults with Parkinson’s disease (PD). Using a one-group pretest-posttest design, 17 community-dwelling adults (mean age 71.51 years) with mild to moderate idiopathic PD (Stage I, II, or III on the Hoehn and Yahr scale) and stable medication use completed a 5-day, 90-min/day Tai Chi exercise-evaluation program. Outcome measures included face-to-face exit interviews on appropriateness and safety and physical performance (i.e., 50-ft speed walk, up-and-go, functional reach). At the end of this brief intervention, exercise adherence was 100% and the program was shown to be safe. Exit interviews indicated that the program was well received by all participants with respect to program appropriateness, participant satisfaction and enjoyment, and intentions to continue. Furthermore, a significant pretest-to-posttest change was observed at the end of the 5-day program in all three physical-performance measures (p < .05). The results of this pilot evaluation suggest that Tai Chi is an appropriate physical activity for older adults with PD and might also be useful as a therapeutic exercise modality for improving and maintaining physical function. These preliminary findings warrant further investigation.
