Internet psychoeducational interventions improve employees' mental health. However, implementing them for employees in micro- and small-sized enterprises (MSEs) is challenging.
This randomized controlled trial examined the effectiveness of a fully automated text-based stress management program, "WellBe-LINE," in improving mental health and job-related outcomes for employees in workplaces with fewer than 50 employees.
The program was developed based on stakeholder interviews and surveys of 1000 employees at MSEs. Adult full-time employees at an enterprise with fewer than 50 employees were recruited from registered members of a web survey company in Japan. Participants were randomly allocated to the intervention or control group (1:1). Participants in the intervention group were invited to register for the program using the LINE app. Psychological distress measured by Kessler 6 (K6) was a primary outcome, with self-administrated questionnaires at baseline, 2-month (post), and 6-month follow-ups. A mixed model for repeated measures conditional growth model analysis was conducted using a group ∗ time interaction as an intervention effect. Implementation outcomes were measured through implementation outcome scales for digital mental health (iOSDMH).
1021 employees were included in this study. No significant effects were shown in any outcome. The reported implementation outcomes were positively evaluated, with 80 % acceptability, 86 % appropriateness, and feasibility (ease of understanding the contents [88 %], frequency [86 %], and length of content [86 %]).
A simple text-message program for employees at MESs was acceptable, appropriate, and feasible; however, it did not result in improved mental health or job-related outcomes.

互联网心理教育干预可改善员工心理健康。然而，对微型和小型企业（MSE）的员工实施此类干预具有挑战性。
本随机对照试验考察了一个基于文本的全自动压力管理程序“WellBe-LINE”对员工人数少于50人的工作场所中员工心理健康和工作相关结果的改善效果。
该程序是在对利益相关者进行访谈以及对1000名微型和小型企业员工进行调查的基础上开发的。从日本一家网络调查公司的注册会员中招募了一家员工人数少于50人的企业的成年全职员工。参与者被随机分配到干预组或对照组（1:1）。干预组的参与者被邀请使用LINE应用程序注册该程序。采用凯斯勒6项量表（K6）测量的心理困扰是主要结局指标，在基线、2个月（干预后）和6个月随访时使用自填问卷进行测量。采用以组*时间交互作用作为干预效应的重复测量混合模型条件增长模型分析。通过数字心理健康实施结果量表（iOSDMH）测量实施结果。
本研究纳入了1021名员工。在任何结局指标上均未显示出显著效果。报告的实施结果得到了积极评价，接受度为80%，适宜性为86%，可行性方面（内容理解难度[88%]、频率[86%]和内容长度[86%]）也较好。
一个针对微型和小型企业员工的简单短信程序是可接受、适宜且可行的；然而，它并未改善心理健康或工作相关结果。
