Studies using yoga have demonstrated initial efficacy for treating symptoms across anxiety disorders, including posttraumatic stress disorder.
Understanding how interventions influence participants' physical activity and what determinants affect continued physical activity behavior change is important because maintenance of the behavior may be critical to continued mental health gains and symptom reduction.
This study investigated change in physical activity and possible psychological mechanisms of physical activity behavior change, including self-efficacy and regulatory motivation, in a randomized controlled trial of yoga for women with post-traumatic stress disorder symptoms (n=38).
Growth curve modeling results showed no significant changes in physical activity or self-efficacy for either group, whereas external motivation decreased significantly in the yoga group but not in the control group.
Investigators of future yoga interventions may want to focus on increasing self-efficacy and internal regulatory motivation, so that physical activity and resultant symptom relief can be maintained.
使用瑜伽的研究已证明其在治疗包括创伤后应激障碍在内的各种焦虑症症状方面具有初步疗效。
了解干预措施如何影响参与者的身体活动，以及哪些决定因素会影响身体活动行为的持续改变，这很重要，因为行为的维持可能对持续改善心理健康和减轻症状至关重要。
在一项针对有创伤后应激障碍症状的女性（n = 38）的瑜伽随机对照试验中，本研究调查了身体活动的变化以及身体活动行为改变可能的心理机制，包括自我效能感和调节动机。
生长曲线建模结果显示，两组的身体活动或自我效能感均无显著变化，而瑜伽组的外部动机显著下降，对照组则未下降。
未来瑜伽干预措施的研究者可能希望专注于提高自我效能感和内部调节动机，以便维持身体活动并由此缓解症状。
