Yang Style Tai Chi is a slow moving form that affects balance postural alignment & concentration
5 items to assess perception of ability to perform Tai Chi regularly in the face of barriers (ie. Pain, boredom etc.)
0-100 confidence scale (0=very little confidence, 100=complete confidence)
Performance scale self-efficacy
3 item task-specific, time-based
Degree of confidence in ability to successfully perform a series of slow, rhythmically changing body position movements
0-100 confidence scaleResearch Methods (con’t):Outcome Measures
(intervention group responded in class within 1 week, control group responded by mail)
Both types of efficacy increase over time
Initial boost from baseline to 2nd observation
Maintenance from 2nd to 3rd observation
Class attendance was significantly predicted by the changes in the 2 types of efficacy
Both types of efficacy decreased over timeMain Findings (con’t)
Change in barrier efficacy between Tai Chi and Control
Change in performance efficacy between Tai Chi and Control
