Objective <p>This study aimed to evaluate the validity and reliability of the Turkish version of the Barcelona Bipolar Eating Disorder Scale (BEDS), which can facilitate screening for comorbid eating disorders (EDs) in bipolar disorder (BD) patients.</p> Methods <p>A total of 100 BD patients and 129 healthy controls (HCs) were included in the study conducted at Ankara Etlik City Hospital Psychiatry Clinic. These patients were diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), and the Structured Clinical Interview for DSM-5 (SCID-5). Sociodemographic forms, the Turkish version of the BEDS, the Young Mania Rating Scale (YMRS), the Hamilton Depression Rating Scale (HAM-D), the Brief Psychiatric Rating Scale (BPRS), the Bulimic Investigatory Test, Edinburgh (BITE), and the Dutch Eating Behavior Questionnaire (DEBQ) were used to assess validity and reliability.</p> Results <p>No statistically significant differences were found between the patient and control groups regarding the BITE and BEDS total scores. For the DEBQ, no significant group differences were observed in the total, restrained eating, or external eating scores, whereas the healthy control group had higher emotional eating scores. The correlation coefficient between each item and the total score ranged from 0.313 to 0.644. Cronbach’s alpha for the scale was 0.821. The removal of any items from the original scale did not lead to an improvement in Cronbach’s alpha. The BEDS score was found to be significantly correlated with the BITE score, DEBQ total score, emotional eating score, and external eating score (<i>p</i> &lt; 0.001). There was no correlation between the BEDS score and the DEBQ restrictive eating subscale, YMRS, BPRS, or HAM-D scale scores.</p> Conclusion <p>The Turkish version of the BEDS is a valid and reliable scale that can be used as an assessment tool in the evaluation of eating disorders in the Turkish BD population.</p>
