Case Study

A group of research was interested in exploring coping mechanisms in the workplace.

The researchers defined coping mechanisms as “the strategies individuals utilise to manage both internal and external stressful situations”. The researchers then created an interactive educational programme designed to foster positive coping strategies amongst employees. The focus of the study was to explore whether the programme was effective.

The researchers began by obtaining permission to conduct the study from the University of the Witwatersrand Ethics Committee. Once permission was obtained, the researchers approached the CEO of a local corporate company located in the North of Johannesburg and obtained permission to carry out their study at this company.

All company employees who agreed to participate (530 employees; 350 females, 180 males) in the study were asked to complete a brief demographic questionnaire as well as the Brief COPE Inventory. The participants were randomly assignment to group A (265 employees) and group B (265 employees). All participants in Group A attended three two-hour presentations scheduled after work hours over two weeks during which they were presented with the interactive coping mechanisms educational programme. This included reading and discussing stories about specific coping strategies, watching videos and role-playing.

Participants in Group B attended three two-hour presentations scheduled after work hours over two weeks during which they were asked to discuss their day at work. At the end of the two weeks, all of the employees (Group A and group B) were asked to re-complete the Brief COPE Inventory.

The Brief COPE Inventory is a 28-item self-report scale which focuses on understanding the frequency with which people use different coping strategies in response to various stressful events or situations. The Brief Cope Inventory has fourteen subscales, each of which is answered on a four-point scale ranging from ‘I haven’t been doing this’(1) to ‘I’ve been doing this a lot’ (4). Higher scores in each scale indicates preference towards using a specific coping strategy.

Cronbach Alpha Coefficients for the Brief COPE Inventory range from 0.68 to 0.77 across the different subscales. The Brief COPE Inventory has been found to relate positively with the Dyadic Coping Inventory. The scale was developed in English in the United States of America, and has not been widely used in the South African context.

Analysis of the results indicated that there was a significant difference in the type of coping strategies utilised by employees in group A when compared to group B after the presentations; on this basis, the researchers concluded that the programme was effective.
