Positive psychology interventions have been found to enhance well-being and decrease clinical symptomatology. However, it is still unknown how flourishing can also be increased. Although multicomponent interventions seem to be necessary for this purpose, different formats can be used. A cost-effective approach could be a positive psychology-based self-help book with tailored email support to reach large target groups and to prevent dropout.
This study will evaluate the efficacy of a comprehensive multicomponent self-help intervention with or without email support on well-being and flourishing, and will seek to determine the working mechanisms underlying the intervention.
In this 3-armed, parallel, randomized controlled trial, 396 participants with low or moderate levels of well-being and without clinical symptomatology will be randomly assigned to (1) a self-help book condition with weekly email support, (2) a self-help book condition without email support but with a weekly information email, or (3) a waiting list control condition. Online measurements will be assessed at baseline, at post-test (3 months after baseline), and at 6 and 12 months after baseline.
The primary outcomes are well-being and flourishing (ie, high levels of well-being). Secondary outcomes are the well-being components included in the intervention: positive emotion, use of strengths, optimism, self-compassion, resilience, and positive relations. Other measures include depressive and anxiety symptoms, personality traits, direct medical and non-medical costs, life-events, and client satisfaction.
This study will add knowledge to the efficacy and cost-effectiveness of a multicomponent positive psychology intervention. We will also explore who can benefit most from this intervention. If the intervention is found to be effective, our results will be especially relevant for public mental health services, governments, and primary care.

研究发现积极心理学干预可提升幸福感并减轻临床症状。然而，尚不清楚如何才能增强蓬勃发展感。尽管为此似乎需要多成分干预措施，但可以采用不同的形式。一种具有成本效益的方法可能是一本基于积极心理学的自助书籍，并提供量身定制的电子邮件支持，以覆盖大量目标群体并防止退出。
本研究将评估一种综合多成分自助干预措施（有或无电子邮件支持）对幸福感和蓬勃发展感的疗效，并试图确定该干预措施的作用机制。
在这项三臂、平行、随机对照试验中，396名幸福感处于低或中等水平且无临床症状的参与者将被随机分配到：（1）每周有电子邮件支持的自助书籍组；（2）无电子邮件支持但每周有信息邮件的自助书籍组；或（3）等待列表对照组。将在基线、测试后（基线后3个月）以及基线后6个月和12个月进行在线测量。
主要结果是幸福感和蓬勃发展感（即高水平的幸福感）。次要结果是干预措施中包含的幸福感成分：积极情绪、优势利用、乐观、自我同情、复原力和积极关系。其他测量指标包括抑郁和焦虑症状、人格特质、直接医疗和非医疗成本、生活事件以及客户满意度。
本研究将为多成分积极心理学干预的疗效和成本效益增添知识。我们还将探索谁能从这种干预中获益最多。如果发现该干预措施有效，我们的结果将对公共心理健康服务、政府和初级保健尤为重要。
