Background/Purpose: Physical activity has benefits for reducing levels of anxiety. However, factors that
affect physical activity participation for individuals with anxiety disorders have not been well studied.
Here, we aimed to clarify the roles of state and trait anxiety in physical activity participation by examining
relationships among seven major study variables in Taiwanese adults with anxiety disorders.
Methods: A multi-site, cross-sectional explanatory design was used. Data were collected using one interview
and five self-administered questionnaires. The sample included 144 Taiwanese adults diagnosed
with anxiety disorders.
Results: State and trait anxiety were significantly correlated with most of the study variables. Physical
activity participation by subjects with anxiety disorders was significantly correlated with state anxiety, benefits
of activity, self-efficacy for activity, and social support for activity. When age, sex, and education were
controlled in the analysis, state anxiety was associated significantly and negatively with physical activity,
benefits of activity, and self-efficacy for activity, and was correlated positively with barriers to activity. Trait
anxiety was found to be correlated significantly and negatively with benefits of activity and self-efficacy for
activity, and correlated positively with barriers to activity.
Conclusion: State anxiety demonstrated greater power than trait anxiety in its relationship with physical
activity. These findings suggest that clinical mental health professionals should consider state anxiety
when encouraging Taiwanese adults with anxiety disorders to engage in physical activity. [J Formos Med
