Abstract

Objective: Mindfulness training can relieve posttraumatic stress disorder (PTSD) symptoms in military veterans and others but is inconsistently accessible. Self-guided mobile apps could improve access but their acceptability, feasibility, and benefits for veterans with PTSD have not been established. We conducted a pilot randomized trial of Mindfulness Coach (MC), a free, publicly available, trauma-informed mobile app tailored to veterans.

Method: U.S. veterans with PTSD (n = 173) were randomized to self-guided use of MC or waitlist control (WLC) with 8-week follow-up. Clinical outcomes were PTSD symptoms (PTSD Symptom Checklist-5), depression symptoms (Patient Health Questionnaire, nine item), and psychosocial functioning (Brief Inventory of Psychosocial Functioning). Primary analyses were intent-to-treat using linear mixed models with maximum likelihood estimation. App uptake, objective usage, and usability ratings measured acceptance and feasibility.

Results: Participants varied in age, gender, and ethnoracial identity; most reported recent mental health care utilization. Although study attrition was high (68.4% overall) due to participant dropout (treatment: 43.0%; control: 43.7%) and technical study issues (23% overall), diagnostic tests showed no evidence of bias due to missingness. Study completers (MC: n = 19; WLC: n = 37) showed medium effects on PTSD symptoms (b = -9.31, d = -0.69) and depression (b = -3.10, d = -0.52). Higher-intensity users showed greater benefits. App engagement trended lower for women and minoritized subpopulations. No changes were observed in psychosocial functioning. Usability and helpfulness ratings were favorable.

Conclusions: Transdiagnostic clinical benefits indicate promise for MC as a public health resource for veterans with PTSD. Further study is warranted to confirm these benefits and ensure consistent engagement across subpopulations. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

对患有创伤后应激障碍的退伍军人使用自我指导正念教练移动应用程序的临床益处:随机对照试验
目的:正念训练可以缓解退伍军人和其他人的创伤后应激障碍(PTSD)症状,但其可获得性并不一致。自助式移动应用程序可以改善获取途径,但其可接受性、可行性以及对患有创伤后应激障碍的退伍军人的益处尚未得到证实。我们对 "正念教练"(Mindfulness Coach,简称 MC)进行了试点随机试验:方法:患有创伤后应激障碍的美国退伍军人(n = 173)被随机分配到自我指导使用 MC 或候补对照组(WLC),并进行为期 8 周的随访。临床结果包括创伤后应激障碍症状(创伤后应激障碍症状检查表-5)、抑郁症状(患者健康问卷,九项)和社会心理功能(社会心理功能简表)。主要分析采用最大似然估计线性混合模型进行意向治疗。应用程序的使用率、客观使用率和可用性评分衡量了接受度和可行性:结果:参与者的年龄、性别和种族身份各不相同;大多数人表示最近使用过心理保健服务。虽然由于参与者辍学(治疗:43.0%;对照:43.7%)和技术性研究问题(总体为 23%),研究的自然减员率较高(总体为 68.4%),但诊断测试结果显示,没有证据表明因遗漏而产生偏差。研究完成者(MC:n = 19;WLC:n = 37)对创伤后应激障碍症状(b = -9.31,d = -0.69)和抑郁(b = -3.10,d = -0.52)显示出中等效果。高强度用户显示出更大的益处。女性和少数民族亚群的应用参与度呈下降趋势。在社会心理功能方面未观察到任何变化。可用性和有用性评价良好:跨诊断临床效益表明,MC 有望成为创伤后应激障碍退伍军人的公共卫生资源。需要进一步研究以确认这些益处,并确保不同亚人群的参与度保持一致。(PsycInfo Database Record (c) 2024 APA,保留所有权利)。
