Objectives

Narrative objectives1

This study aims to test the following two hypotheses.

1) The gratitude intervention would improve work engagement, as the primary outcome, in workers assigned to the intervention group, compared with those in the control group.

2)The gratitude intervention would improve the level of gratitude at work, personal resources (self-efficacy and sense of coherence), job resources (support from supervisors and coworkers), well-being (eudaimonic well-being at work and psychological distress), and work performance ( as secondary outcomes) in workers assigned to the intervention group, compared with those in the control group.

Assessment

Primary outcomes

(It will be measured before randomization as baseline, 1, 3 and 6 months follow-up after baseline)

Key secondary outcomes

1) Gratitude at work measured by the gratitude at work scale
2) Self-efficacy measured by the self-efficacy scale
3) Sense of coherence measured by the sense of coherence scale.
4) Supervisor and coworker support measured by the Brief Job Stress Questionnaire (BJSQ)
5) Eudaimonic well-being at work measured by the 24-item University of Tokyo Occupational Mental Health well-being scale (TOMH well-being 24)
6) Psychological distress will be measured by the K6

Interventions/Control_1

The gratitude intervention is a four-week program implemented on an organization basis. It consists of three elements: psychoeducation, gratitude lists: making written lists of several things for which one is grateful regularly, and behavioral gratitude expression: expressing gratitude to others. Psychoeducation is delivered for a week in week 1. Then, gratitude lists and behavioral gratitude expressions are conducted three weeks in week 2 to week 4. Gratitude lists are programs that correspond to increasing personal resources, and behavioral gratitude expressions are programs that correspond to increasing job resources. Psychological education aims to provide an overview of the program and help participants implementation of these activities.

In this study, we regard a group of departments, sections, or teams working together in a company as an organization.

Interventions/Control_2

Participants belonging to the organizations allocated to the control group do not receive any intervention programs until they complete the 6-month follow-up survey. After that, those enrolled in the control group will receive the same intervention program as the intervention group.
