Many active duty service members suffer from major depressive disorder (MDD). Although traditional treatments exist, alternative approaches may also be effective in treating depressive symptoms. Previous research has shown that physical activity has significant positive effects on depression symptoms in individuals with MDD, and that these benefits may be enhanced when physical activity occurs in a natural environment. Even though physical activity (i.e., hiking, walking) in natural environments has been shown to reduce depressive symptoms, water-based activity occurring in a natural environment (e.g., surfing) may produce even greater improvements in depressive symptoms. We detail an ongoing randomized controlled trial (RCT) comparing the efficacy of surf therapy and hike therapy with respect to immediate and longer-term psychological, physical, and functional outcomes in active duty service members with MDD. We describe the methodological development of this RCT evaluating novel treatment approaches and discuss considerations for evaluating physical activity interventions in a naturalistic setting.
许多现役军人患有重度抑郁症（MDD）。尽管存在传统治疗方法，但替代方法在治疗抑郁症状方面可能也有效。先前的研究表明，体育活动对患有MDD的个体的抑郁症状有显著的积极影响，并且当体育活动在自然环境中进行时，这些益处可能会增强。尽管已证明在自然环境中的体育活动（如徒步旅行、散步）可减轻抑郁症状，但在自然环境中进行的水上活动（如冲浪）可能会在抑郁症状方面产生更大改善。我们详细介绍了一项正在进行的随机对照试验（RCT），该试验比较了冲浪疗法和徒步疗法对患有MDD的现役军人的即时和长期心理、身体及功能结局的疗效。我们描述了这项评估新型治疗方法的RCT的方法学发展，并讨论了在自然环境中评估体育活动干预措施的注意事项。
