Coping With Strain (CWS) course - its effects on depressive symptoms: A four-year longitudinal randomized controlled trial.
The Coping With Strain (CWS) course is a modification of the Coping With Depression (CWD) course. CWD is by far the most studied psycho-educational intervention to reduce and prevent depression, but CWD has never been tested in a randomized controlled trial in the workplace. This study seeks to examine the extent to which CWS, on a short-term and a long-term basis, reduces depressive symptoms in employees. After advertising at workplaces, 119 employees were randomized into Intervention Group I (IG1), which immediately participated in CWS, or Intervention Group II (IG2), which functioned as a control group for six months until its participation in CWS. The follow up period lasted for four years in both IG1 and IG2. Linear mixed models were fitted to the data. Depressive symptoms were significantly reduced during the course. The reduction of depressive symptoms was maintained over a period of four years in both IG1 and IG2, although there is a slight increase towards the end of the follow-up period. CWS is effective in reducing depressive symptoms among employees. The effects are long lasting and may be maintained over a period of four years.
