A Cognitive-behavioral Intervention of Rumination for Perfectionists

"The B-experimental phase consists in a 6-session intervention targeting rumination and lasting for 3 weeks. The intervention was derived from 3 manuals: Rumination-Focused Cognitive-Behavioral Therapy for Depression (Watkins, 2016), Overcoming Perfectionism (Shafran et al., 2010), and Cognitive-Behavioral Treatment of Perfectionism (Egan et al., 2014). Participants will attend 2 sessions per week at home. Each week will end with an individual 30 minutes-debriefing session with an experimenter, to ascertain understanding of session content and homework.~Intervention sessions will be given in paper format to participant after the A-baseline-phase. A paper diary was also provided for homework, in addition to the session content caneva. Each session contains (a) theoretical content on ruminations linked to perfectionism, (b) exercises to create alternative habits to ruminations, and (c) homework to become aware of ruminations and to experiment with alternatives."
