Emotion regulation group skills training: a pilot study of an add-on treatment for eating disorders in a clinical setting

BACKGROUND: Emotion regulation difficulties appear to play a role in the development and maintenance of several eating disorders. This pilot study aimed at examining whether a short add-on group skills training in emotion regulation for young adults with different eating disorders was feasible in a psychiatric clinical setting. We also investigated if the treatment increased knowledge of emotions, and decreased self-reported difficulties with emotion regulation, alexithymia, symptoms of eating disorder, anxiety and depression, as well as clinical impairment. METHODS: Six skills training groups were piloted with a total of 29 participants (M = 21.41 years, SD = 1.92). The treatment consisted of five sessions dealing with psychoeducation about emotions and emotion regulation skills training. Paired samples t-test was used to compare differences between before-and-after measures. RESULTS: The primary outcomes measures difficulties in emotion regulation (p < 0.001) and alexithymia (p < 0.001) showed significant improvement after treatment. The total eating disorder score (p = 0.009) was also significantly reduced, as was clinical impairment (p < 0.001). Acceptance/valued direction, identifying primary emotions and learning about secondary emotions was rated as especially helpful. CONCLUSIONS: This preliminary pilot study showed that group training targeting emotion regulation skills was feasible and appreciated by participants, as well as being potentially promising as an adjunctive treatment for different eating disorders. Further controlled studies are needed. TRIAL REGISTRATION: The study was retrospectively registered NCT04148014 on October 30th 2019.
