Developing and Evaluating an Online Post-Traumatic Growth Program for Firefighters.

We evaluated how an online post-traumatic growth program affected rumination, social support, and post-traumatic growth. We recruited 33 firefighters from two Korean provinces and employed a nonequivalent control group pretest-post-test design. We administered the pretest for the intervention group (n = 16), consisting of eight sessions with an online workbook and messenger group counseling. We conducted post-tests immediately after the program and 4 weeks later. Post-traumatic growth and social support increased significantly. There were no statistically significant differences for intrusive or deliberate rumination. Psychological support programs should be developed to reflect firefighters' work characteristics and needs, including programs designed to induce rumination.
