A thesis is an aptitude test for students. The approval of the thesis is proof that the student has sufficient research and reporting skills to graduate but does not guarantee the quality of the research and the results of the research as such, and the thesis is therefore not necessarily suitable to be used as an academic source to refer to. If you would like to know more about the research discussed in this thesis and any publications based on it, to which you could refer, please contact the supervisor mentioned.
Abstract
The present study aimed to replicate the findings by van Doornik et al. (2024) on the effectiveness of their newly introduced Meaning Centered Psychotherapy for Eating Disorders (MCP-ED) treatment protocol outside of the Covid-19 pandemic. Research focused on whether MCP-ED is effective in changing its mechanism of change, meaning in life (MiL), as well as its effects on satisfaction with normative life domains. We hypothesized that both meaning in life and satisfaction with normative life domains would be significantly higher after the intervention. A randomized controlled trial was conducted with 129 young undergraduate women with high shape and weight concerns. Group allocation was randomized, with groups consisting of an intervention group (n=62) and a waitlist control group (n=67). Two ANCOVA’s were performed to analyze the data. Results included a strong positive significant effect on meaning in life, and a small to moderate positive significant effect on satisfaction with normative life domains at post-treatment measurement. This successful replication provides robust support toward the MCP-ED treatment protocol being effective in positively changing its proposed mechanism of change, and paves the way for further research into meaning-centered approaches being useful as potential complement to CBT-E in the treatment of eating disorders.
