Abstract
An intervention consisting of a thorough examination of the psychological worksite problems and a follow-up with feedback and recommendations was made in four different office worksites. One of the sites («active» group) was more organizational change-oriented than the others («passive» group). The course was followed before, three times during the 3 months of the intervention, and 4 months after the end of it, by means of three endocrine plasma markers: cortisol, prolactin and testosterone. In both study groups the prolactin levels increased in women during the starting phase of the intervention, whereas in men prolactin levels remained stable with a tendency (p=0.06) towards lowered prolactin levels during the end phase of the intervention in the active group. Cortisol levels increased markedly in the passive group and tended to decrease in the active group during the intervention (two-way interaction p=0.003), particularly in men. These findings may be indicative of feelings of uneasiness. Testosterone increased in the active group only, particularly at the beginning of the intervention and particularly in women, and also increased in a non-intervention control group. Testosterone levels are associated with anabolic activity. An increase may be indicative of a «placebo effect» of the intervention. Testosterone changes were still clearly observable after 4 months.
