The study measured changes in salivary cortisol, testosterone, and melatonin, and self-reported data were collected on psychological stress symptoms (perceived stress, mood disturbance, sleep quality, physical distress symptoms, work readiness, well-being, anxiety, depression, immediate stress).
Results showed significant beneficial effects with GIM after nine weeks in the intervention group, as compared to the wait-list control condition, with large effect sizes found in well-being, mood disturbance, and physical distress; and medium effect size in cortisol concentrations.
Other comparisons of the timing of when the GIM was introduced suggested the earlier the better; there was faster job return and significantly improved perceived stress, well-being, mood disturbance, depression, anxiety, and physical distress symptoms, with early intervention.
In the whole sample, 83% of the participants had returned to work at nine weeks' follow-up. Although this was a small sample and therefore more prone to statistical distortion, these results indicate that GIM is a promising treatment for work-related chronic stress, and further studies are recommended.
