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.

在线跨学科干预对心理健康促进的有效性：一项随机对照试验


迫切需要采取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。本研究的目的是检验结合生活方式医学和积极心理学学科的循证策略的在线跨学科干预是否可以改善心理健康和情绪健康的测量。在澳大利亚和新西兰进行了一项具有等候名单对照的随机对照试验（N = 425，年龄 46.97 ± 14.5，69.9% 女性）。干预组参加了为期10周的在线跨学科干预。心理健康和情绪健康的主要结果测量在基线（第 1 周）、干预后（第 12 周）和干预后 12 周（第 24 周）进行。等候名单控制完成了相同的评估。一般线性模型分析表明，随着时间的推移，干预组在所有结果指标上都比等待名单对照组经历了显着更大的改善：心理健康（F（319）= 7.326，p = 0.007）和活力（F（319）= 9.445 , p = 0.002) 简短调查 (SF-36) 的分量表；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）抑郁、焦虑和压力量表量表（DASS-21）；以及通过生活满意度量表衡量的生活满意度（F(319) = 8.731，p = 0.003）。在干预组中，从第 1 周到第 12 周，所有结果指标均出现显着改善：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）。干预后 12 周，干预组的结果指标仍显着改善。在线跨学科干预改善了心理健康和情绪健康的衡量标准，表明此类干预措施可能有助于心理健康促进和预防。试验注册澳大利亚新西兰临床试验注册中心。 ACTRN12619000993190。 2019年7月12日注册（追溯注册）。 ANZCTRN 是 WHO 主要登记处的一部分。
