There is an urgent need for efficacious interventions to combat the global mental health crisis, and mental health promotion and primary prevention approaches are paramount. The aim of this study is to examine whether an online interdisciplinary intervention that incorporates evidence-based strategies from the disciplines of Lifestyle Medicine and Positive Psychology improves measures of mental health and emotional wellness.
A randomized controlled trial with a wait-list control (N = 425, aged 46.97 ± 14.5, 69.9% females) was conducted in Australia and New Zealand. The intervention group participated in a 10-week online interdisciplinary intervention. Primary outcome measures of mental health and emotional wellness were taken at baseline (Week 1), post-intervention (Week 12), and 12 weeks post-intervention (Week 24). The wait-list control completed the same assessments.
General Linear Modelling analyses indicated that the intervention group experienced significantly greater improvements than the wait-list control group over time in all outcome measures: mental health (F(319) = 7.326, p = 0.007) and vitality (F(319) = 9.445, p = 0.002) subscales of the Short Form Survey (SF-36); depression (F(319) = 7.841, p = 0.005), anxiety (F(319) = 4.440, p = 0.36) and stress (F(319) = 12.494, p < 0.001) scales of the Depression, Anxiety and Stress Scale (DASS-21); and life satisfaction (F(319) = 8.731, p = 0.003) as measured by the Satisfaction With Life Scale. Within the intervention group, significant improvements were observed from Week 1 to 12 in all outcome measures: mental health (10%, t(167) = - 6.423), p < 0.001, dz = 0.50), vitality (22%, t(167) = - 7.043, p < 0.001, dz = 0.54), depression (- 41%, t(167) = 6.189, p < 0.001, dz = 0.48), anxiety (- 38%, t(167) = 5.030, p < 0.001, dz = 0.39), stress (- 31%, t(167) = 6.702, p < 0.001, dz = 0.52) and life satisfaction (8%, t(167) = - 6.199, p < 0.001, dz = 0.48). Improvements in the outcome measures remained significant in the intervention group at 12 weeks post-intervention.
The online interdisciplinary intervention improved measures of mental health and emotional wellness suggesting that such interventions may be useful for mental health promotion and prevention.

目前迫切需要有效的干预措施来应对全球心理健康危机，而心理健康促进和初级预防方法至关重要。本研究旨在探讨一种整合生活方式医学和积极心理学循证策略的在线跨学科干预措施是否可以改善心理健康和情绪健康的衡量标准。
在澳大利亚和新西兰进行了一项随机对照试验，设候补名单对照（N=425，年龄 46.97±14.5，69.9%为女性）。干预组参与了为期 10 周的在线跨学科干预。在基线（第 1 周）、干预后（第 12 周）和干预后 12 周（第 24 周）进行心理健康和情绪健康的主要结局评估。候补名单对照组完成了相同的评估。
一般线性模型分析表明，与候补名单对照组相比，干预组在所有结局测量中均随时间显著改善：心理健康（F（319）=7.326，p=0.007）和活力（F（319）=9.445，p=0.002）的简短形式调查（SF-36）子量表；抑郁（F（319）=7.841，p=0.005）、焦虑（F（319）=4.440，p=0.36）和压力（F（319）=12.494，p<0.001）的抑郁、焦虑和压力量表（DASS-21）；生活满意度（F（319）=8.731，p=0.003）通过生活满意度量表测量。在干预组中，所有结局测量在第 1 周到第 12 周都有显著改善：心理健康（10%，t（167）=-6.423，p<0.001，dz=0.50），活力（22%，t（167）=-7.043，p<0.001，dz=0.54），抑郁（-41%，t（167）=6.189，p<0.001，dz=0.48），焦虑（-38%，t（167）=5.030，p<0.001，dz=0.39），压力（-31%，t（167）=6.702，p<0.001，dz=0.52）和生活满意度（8%，t（167）=-6.199，p<0.001，dz=0.48）。干预组在第 12 周的干预后，结局测量的改善仍然显著。
在线跨学科干预措施改善了心理健康和情绪健康的衡量标准，这表明此类干预措施可能有助于促进和预防心理健康。试验注册澳大利亚和新西兰临床试验注册处。ACTRN12619000993190。于 2019 年 7 月 12 日注册（回顾性注册）。ANZCTRN 是世界卫生组织主要登记处的一部分。
