Abstract
Meaning in life is considered to play a part in eating disorders. More specifically, low meaning in life is associated with high eating disorder symptoms. A new intervention was developed to treat these disorders: the Meaning Centered Intervention adjusted for eating disorders (MCI-ED). This study is a replication of a previous randomized controlled trial by Van Doornik et al. (2023) performed during the lockdown period of Covid. The hypotheses of the current study are that the MCI-ED significantly increases meaning in life and significantly decreases eating disorder symptoms and perfectionism. Participants were adolescent female students at the University of Groningen with high weight and shape concerns. They were on average 19.66 years old (SD= 2.26) and 43.3% reported Dutch to be their primary language. Participants (N=104) were randomly divided between the intervention condition (N=46) and the waitlist condition (N=58). Participants in the intervention condition received six one-hour online intervention sessions with a trainer that revolved around different aspects of meaning in life. Following a pre- and post-test design, all participants were asked to fill in questionnaires about meaning in life, eating disorder symptoms and perfectionism in the 1st and 7th week of the process. Results showed that meaning in life increased significantly and eating disorder symptoms significantly decreased in participants that follow the intervention compared to those that did not. For perfectionism, no significant result was found. This implies that the MCI-ED is effective in treating eating disorder symptoms and increasing meaning in life.
