摘要
背景：工作投入是员工幸福感的重要决定因素。根据工作需求-资源模型，个人资源是工作投入的关键前提之一。增强个人资源可以提高工作投入。此外，积极地反思自己在工作中的成就可能会增加个人资源。因此，需要一种简单的、自我引导的工具，比如一款智能手机应用程序，员工可以用它来记录和反思自己的工作成就。目的：本研究旨在通过一项随机对照试验，评估基于智能手机的日记（即工作投入日记）对日本员工工作投入的影响，该日记促进了日常工作生活的积极反思。方法：通过网络调查公司将600名符合入选标准的日本员工随机分为干预组和等候名单对照组（各300人）。干预组的参与者保持了两周的工作投入日记，他们被要求在一周的开始设定一周的目标，并在一天结束时填写他们的工作成就。等候名单控制组在完成后续调查之前没有接受任何干预。在干预前（T1）、干预后（T2）和干预后3周（T3）对两组的工作投入进行评估。结果：使用意向治疗的重复测量条件增长模型分析的混合模型显示，在整个研究期间，与等候名单对照组相比，干预组的工作投入有显着改善（P=.04）。T1与T2的工作投入效应值较小（Cohen d=0.11 [95% CI -0.06至0.28]），T1与T3的工作投入效应值较小（Cohen d=0.12 [95% CI -0.06至0.28]）。结论：这项随机对照试验表明，我们新开发的基于智能手机的工作积极反思日记有效地提高了日本员工的工作敬业度。未来的研究需要明确长期的干预效果和详细的干预作用机制。
Effects of a Smartphone-Based Positive Reflection Diary on Work Engagement Among Japanese Workers: Randomized Controlled Trial.
Unlabelled:
Background: Work engagement is an important determinant of workers' well-being. According to the job demands-resources model, personal resources are one of the key antecedents of work engagement. Enhancing personal resources leads to improved work engagement. Furthermore, reflecting positively on one's achievements at work may enhance personal resources. Hence, there is a need for a simple, self-guided tool such as a smartphone app that can be used by employees to record and reflect on their work accomplishments.
Objective: This study aimed to evaluate the effect of a smartphone-based diary (ie, Work Engagement Diary) that promotes positive reflection in daily working life on work engagement among Japanese workers in a randomized controlled trial.
Methods: Six hundred Japanese workers who met the inclusion criteria were randomly allocated to either the intervention group or the wait-list control group (300 participants each) via a web survey company. Participants in the intervention group kept the Work Engagement Diary for 2 weeks, whereby they were required to set a weekly goal at the beginning of the week and fill in their work achievements at the end of the day. Those in the waitlist control group did not receive any interventions until they completed a follow-up survey. Work engagement was assessed at preintervention (T1), postintervention (T2), and 3 weeks after intervention (T3) in both groups.
Results: A mixed model for repeated measures conditional growth model analysis using intention-to-treat revealed a significant improvement in work engagement for the intervention group compared to the wait-list control group throughout the study period (P=.04). Effect sizes were small in work engagement for T1 versus T2 (Cohen d=0.11 [95% CI -0.06 to 0.28]) and for T1 versus T3 (Cohen d=0.12 [95% CI -0.06 to 0.28]).
Conclusions: This randomized controlled trial demonstrated that our newly developed smartphone-based positive reflection diary at work effectively improved work engagement among Japanese workers. Future research needs to clarify longer-term intervention effects and detailed mechanisms of the intervention effects.
期刊介绍：
JMIR mHealth and uHealth (JMU, ISSN 2291-5222) is a spin-off journal of JMIR, the leading eHealth journal (Impact Factor 2016: 5.175). JMIR mHealth and uHealth is indexed in PubMed, PubMed Central, and Science Citation Index Expanded (SCIE), and in June 2017 received a stunning inaugural Impact Factor of 4.636.
The journal focusses on health and biomedical applications in mobile and tablet computing, pervasive and ubiquitous computing, wearable computing and domotics.
JMIR mHealth and uHealth publishes since 2013 and was the first mhealth journal in Pubmed. It publishes even faster and has a broader scope with including papers which are more technical or more formative/developmental than what would be published in the Journal of Medical Internet Research.
