Abstract

Veterans' reluctance to engage in mental health treatment coupled with high attrition in such treatment should motivate practitioners and researchers to create innovative ways to treat veterans. Nature-based interventions show promise as a means for addressing veterans' mental health needs. The present study aimed to test the feasibility and acceptability of a manualized nature-based mindfulness intervention for veterans with mental illness. The authors hypothesized that veterans participating in the outdoor, nature-based intervention would report greater reductions in posttraumatic stress disorder symptoms and psychological distress compared to those participating in an indoor mindfulness intervention. Recruited from a Veterans Affairs health care center, 41 veterans with diagnosed mental illness were randomized to either a six-session outdoor group mindfulness intervention or a comparable six-session group mindfulness intervention delivered indoors at the Veterans Affairs. A t test and chi-square tests were used to examine treatment session attendance and treatment completer status. An intent-to-treat framework was used to assess between-group differences by fitting separate generalized linear mixed models with robust estimation for the outcomes of posttraumatic stress disorder symptoms, psychological distress, sense of restoration, and nature connectedness. Results showed that, while the average number of training sessions attended did not statistically differ by group, the number of treatment completers did; there were more treatment completers in the outdoor group. Additionally, linear mixed modeling with robust estimation revealed a significant Condition × Time interaction for posttraumatic stress disorder symptoms. The findings of this research demonstrate that nature-based interventions show promise as an approach to treating veteran mental illness while combating mental health care stigma and increasing treatment completion rates.

退伍军人室内与室外正念干预的比较:一项随机对照试验。
退伍军人不愿接受心理健康治疗,加上这种治疗的高损耗率,应该激励从业人员和研究人员创造治疗退伍军人的创新方法。基于自然的干预措施有望成为解决退伍军人心理健康需求的一种手段。本研究旨在检验一种基于自然的人工正念干预对退伍军人精神疾病的可行性和可接受性。作者假设,与参加室内正念干预的退伍军人相比,参加户外、以自然为基础的干预的退伍军人报告说,创伤后应激障碍症状和心理困扰的减少幅度更大。41名被诊断患有精神疾病的退伍军人从退伍军人事务卫生保健中心招募,被随机分为两组,一组在户外进行为期6次的小组正念干预,另一组在退伍军人事务中心进行为期6次的小组正念干预。采用t检验和卡方检验检验治疗出勤率和治疗完成者状态。治疗意向框架通过拟合单独的广义线性混合模型来评估组间差异,该模型对创伤后应激障碍症状、心理困扰、恢复感和自然联系的结果进行了稳健估计。结果显示,虽然参加培训的平均次数在组间没有统计学差异,但完成治疗的人数有统计学差异;户外组有更多的治疗完成者。此外,具有稳健估计的线性混合模型揭示了创伤后应激障碍症状的显著条件×时间相互作用。本研究的结果表明,基于自然的干预措施有望作为一种治疗退伍军人精神疾病的方法,同时打击精神卫生保健耻辱和提高治疗完成率。(PsycInfo Database Record (c) 2025 APA,版权所有)。
