Effectiveness of an online text-based stress management program for employees who work in micro- and small-sized enterprises: A randomized controlled trial.

Background: Internet psychoeducational interventions improve employees' mental health. However, implementing them for employees in micro- and small-sized enterprises (MSEs) is challenging.

Objectives: 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.

Implementation of an internet-based stress management program in micro- and small-sized enterprises: a study protocol for a pre-post feasibility study of the effectiveness-implementation hybrid type 2 trial.

Background: Although internet-based stress management programs are proven effective in improving mental health among workers, micro- and small-sized enterprises (MSEs), lacking in occupational healthcare services, face challenges implementing them. To address this gap, this study will develop the program with stakeholders at MSEs to aim for real-world implementation.

Objectives: This paper describes a study protocol for a pre-post feasibility study of an effectiveness-implementation hybrid type 2 trial of text-based internet-based programs ("WellBe-LINE") in MSEs with less than 50 employees.
