Examination of executive function skills in obsessive compulsive disorder and eating disorders in comparison with non-clinical group

Studies have found that people diagnosed with obsessive compulsive disorder (OCD) have impairments in their executive function skills. There are findings in the literature that people with anorexia nervosa (AN) and bulimia nervosa (BN), which are similar to OCD in terms of transdiagnostic risk factors, also have impairments in executive function skills. The aim of this study is to obtain information about the pattern and severity of impairments that may occur in the executive function skills, which is a transdiagnostic risk factor of people receiving treatment with a diagnosis of OCD, AN and BN in Turkish culture, and the similarities and differences in the executive function skills of individuals with different diagnoses. In the study, Yale – Brown Obsession Compulsion Scale-Self-Report Form (Y-BOCS), Eating Attitude Test Short Form (YTT-26), Depression Stress Anxiety Scale-21 (DASS-21), Berg (Wisconsin) Card Sorting Test (BCST), Go/No-Go Task, Stop Signal Test (STT), Stroop Color Test, Auditory Consonant Trigrams (ACT), Corsi Block Tapping Task (CBTT), Tower of London Test (TOL) were used as data collection tools. SPSS package program was used for statistical evaluation of the data. Analysis of covariance was applied to evaluate whether the groups differ in terms of executive function components. Hierarchical regression analysis was conducted to examine the direct and indirect relationships between variables.
