Abstract:Introduction: Eating disorders are psychiatric disorders with the highest mortality rate of all mental illnesses. Although much research has been done in this field, treatment and recovery of various eating disorders is still challenging. Literature review indicates that certain personality traits impede individuals to recover from severe diseases. The aim of this study is to provide insight in the relationship between certain individual personality traits and eating disorders. It will be explored to what extent client factors and personality factors are predictive for the treatment intensity and outcome of patients with eating disorders. Methods: A longitudinal observational study-design was conducted. The investigation took place over a period of two years. For this study, the data of the first year of treatment were used. The Routine Outcome Monitoring (ROM) was carried out at 5 measurements during treatment. The ROM consists of The Outcome Questionnaire 45 (OQ-45), the Eating Disorder Questionnaire (EDE-Q) and the Mental Health Continuum- short form (MHC-SF). To investigate several personality aspects, participants filled in the Personality Inventory for DSM-5 (PID-5) and the Impact Herstel Inventarisatie (IHI). Two groups of participants were included in the study. The PID-5 group consists of 207 participants and the IHI-group was made up of 378 participants. Results: There were significant improvements in psychopathology and mental health over the first year of treatment in the total group. Furthermore, results revealed that high scores on client factors are related to more intense treatment and more general psychopathology. Higher scores on detachment are also related to more intense treatment. Moreover, people with high scores on negative affect reported more general- and eating disorder psychopathology. They also reported lower levels of mental health. High scores on psychoticism were related to less mental health. Because treatment of eating disorder is so complex, further research in this field is needed.
