Mental health issues pose a serious concern in the workplace for the huge productivity loss and financial burden associated with it. Unlike the traditional 'fixing-what-is-wrong' approach, positive psychology offers a less-stigmatized way to promote mental health. Psychological capital, a concept originated from positive psychology, has been proven effective in improving mental well-being and work performance. However, little evidence exists for its implementation among Asian working population or its cost-benefit for organizations adopting such promotion strategy. The current study is designed to assess the protective effects of a web-based psychology capital intervention among Hong Kong working population on individuals' mental health and work performance, as well as organizations' return-on-investment.
METHODS/DESIGN: A two-arm randomized controlled trial design will be adopted. Eligible working adults will be randomly allocated to either the intervention group or the waiting-list control group, with 177 participants in each arm. The intervention, which consists of four web-based training sessions, each targeting one of the psychological capital components (hope, efficacy, optimism and resilience), will be implemented over a 4-week period. On-line surveys will assess the participants in each group at baseline, intervention completion, 1 and 3 months after the completion. The primary outcome is individuals' psychological capital level; secondary outcomes include individuals' well-being, depressive symptoms, work engagement and productivity. Return-on-investment will be calculated from the employers' perspective based on productivity gain, savings in medical expenditure, as well as operation and time costs. Analysis will follow the intention-to-treat principle.
This is the first experimental study that explores the applicability of psychological capital development among Asian population. Through investigating changes in individuals' work productivity from absenteeism and presenteeism, this will be one of the few studies that quantify productivity gains from any type of mental health promotion. By demonstrating effectiveness in improving mental well-being and a positive return-on-investment rate, the study may help convince more uptake of similar positive psychology interventions at workplace in Asia and elsewhere.

心理健康问题在工作场所引发了严重关注,因为它会导致巨大的生产力损失和经济负担。与传统的“修复问题”方法不同,积极心理学提供了一种较少污名化的促进心理健康的方式。心理资本是一个源自积极心理学的概念,已被证明在改善心理健康和工作绩效方面有效。然而,在亚洲工作人群中实施心理资本的证据很少,对于采用这种促进策略的组织,其成本效益也缺乏相关研究。本研究旨在评估基于网络的心理资本干预对香港工作人群心理健康和工作绩效的保护作用,以及组织的投资回报率。
方法/设计:将采用双臂随机对照试验设计。符合条件的在职成年人将被随机分配到干预组或等待名单对照组,每组177名参与者。干预措施包括四个基于网络的培训课程,每个课程针对心理资本的一个组成部分(希望、效能、乐观和韧性),将在4周内实施。在线调查将在基线、干预完成时、完成后1个月和3个月对每组参与者进行评估。主要结果是个体的心理资本水平;次要结果包括个体的幸福感、抑郁症状、工作投入和生产力。投资回报率将从雇主的角度根据生产力提高、医疗支出节省以及运营和时间成本来计算。分析将遵循意向性分析原则。
这是第一项探索心理资本发展在亚洲人群中适用性的实验研究。通过调查个体因旷工和出勤主义导致的工作生产力变化,这将是少数几项量化任何类型心理健康促进带来的生产力提高的研究之一。通过证明在改善心理健康和积极的投资回报率方面的有效性,该研究可能有助于说服亚洲和其他地区的工作场所更多地采用类似的积极心理学干预措施。
