背景:许多研究证明了数字干预对改善大学生心理健康的有效性。然而,这些干预措施的低参与率是一个持续的挑战,可能会影响有效性.Brief,诊断,基于网络的视频干预能够针对影响大学生的关键心理健康和相关问题,并且可能对该人群更具吸引力和可及性。
目的:本研究使用2臂随机对照试验来评估UniVirtualClinic-Lite(UVC-Lite)的有效性,一个完全自动化的,诊断,基于网络的视频干预,相对于注意力控制条件。主要结果是抑郁症和广泛性焦虑症的症状。次要结果包括心理困扰,社交焦虑症状,身体欣赏,生活质量,幸福,功能,一般自我效能感,学业自我效能感,帮助寻求。还评估了计划使用(干预措施的吸收和参与度)和满意度。
方法:从澳大利亚的大学招募了患有轻度至中度痛苦症状的大学生(n=487),并随机分配接受UVC-Lite干预或针对一般健康状况的注意力控制条件,为期6周。UVC-Lite包括12个模块,每个包括一个简短的动画视频和一个附带的练习。在12个模块中,7还包括简短的症状筛查测验。结果在基线评估,干预后,干预后3个月和6个月。
结果:使用混合模型重复测量方差分析,在意向治疗基础上分析主要和次要结果。在任何主要或次要结局上,相对于对照条件,干预均未发现有效。虽然67.9%(114/168)的参与者访问了至少1个干预模块,模块完成度极低。参与该计划的人(完成至少1个视频)和基线困扰较高的人(困扰问卷-5分≥15分)的亚组分析未显示随时间的变化情况之间的任何差异。然而,在基线症状较高的人群中,摄取(访问至少1个视频)和参与(完成至少1个视频)较高.对干预的满意度很高。
结论:UVC-Lite干预相对于对照方案无效,尽管它与学生的高满意度有关,但与症状恶化无关。鉴于大学在满足精神卫生服务需求方面面临的挑战,灵活和可访问的干预措施,如UVC-Lite有可能帮助学生管理心理健康问题的症状。然而,低摄取和参与度(特别是在症状学水平较低的学生中)是需要进一步关注的重大挑战。未来的研究应该在更有症状的样本中检查干预的有效性,以及优化有效参与干预的实施途径。

BACKGROUND: Numerous studies have demonstrated the effectiveness of digital interventions for improving the mental health of university students. However, low rates of engagement with these interventions are an ongoing challenge and can compromise effectiveness. Brief, transdiagnostic, web-based video interventions are capable of targeting key mental health and related issues affecting university students and may be more engaging and accessible for this population.
OBJECTIVE: This study used a 2-arm randomized controlled trial to evaluate the effectiveness of Uni Virtual Clinic-Lite (UVC-Lite), a fully automated, transdiagnostic, web-based video intervention, relative to an attention-control condition. The primary outcomes were symptoms of depression and generalized anxiety disorder. The secondary outcomes included psychological distress, social anxiety symptoms, body appreciation, quality of life, well-being, functioning, general self-efficacy, academic self-efficacy, and help seeking. Program use (intervention uptake and engagement) and satisfaction were also assessed.
METHODS: University students (n=487) with mild to moderate symptoms of distress were recruited from universities across Australia and randomly allocated to receive access to the UVC-Lite intervention or an attention-control condition targeting general health for a period of 6 weeks. UVC-Lite includes 12 modules, each comprising a brief animated video and an accompanying exercise. Of the 12 modules, 7 also included a brief symptom screening quiz. Outcomes were assessed at baseline, postintervention, and 3- and 6-months postintervention.
RESULTS: The primary and secondary outcomes were analyzed on an intention-to-treat basis using mixed models repeated measures ANOVA. The intervention was not found to be effective relative to the control condition on any of the primary or secondary outcomes. While 67.9% (114/168) of participants accessed at least 1 module of the intervention, module completion was extremely low. Subgroup analyses among those who engaged with the program (completed at least 1 video) and those with higher baseline distress (Distress Questionnaire-5 score ≥15) did not reveal any differences between the conditions over time. However, uptake (accessing at least 1 video) and engagement (completing at least 1 video) were higher among those with higher baseline symptoms. Satisfaction with the intervention was high.
CONCLUSIONS: The UVC-Lite intervention was not effective relative to a control program, although it was associated with high satisfaction among students and was not associated with symptom deterioration. Given the challenges faced by universities in meeting demand for mental health services, flexible and accessible interventions such as UVC-Lite have the potential to assist students to manage symptoms of mental health problems. However, low uptake and engagement (particularly among students with lower levels of symptomatology) are significant challenges that require further attention. Future studies should examine the effectiveness of the intervention in a more highly symptomatic sample, as well as implementation pathways to optimize effective engagement with the intervention.
