Validity and Reliability of the Turkish Version of Mahony Psychological Assessment for Bariatric Surgery

The aim of this study was to determine the validity and reliability of the Turkish version of Mahony Psychological Assessment for Bariatric Surgery which can be easily administered and used as a guide by health professionals who will be included in the treatment of patients who are potential candidates for bariatric surgery.

A total of 310 patients who were admitted to health institutions for bariatric surgery in 3 different provinces of Turkey answered these questions in the Turkish translation of Mahony Psychological Assessment for Bariatric Surgery. Eating disorder examination questionnaire was also administered to the patients in addition to Mahony Psychological Assessment for Bariatric Surgery.

Early life problems due to weight scores of women were significantly higher than men (P = .001). Among the age groups, both the early life problems due to weight scores (P = .008) and dysphoric feelings about weight scores (P < .001) of the 18-44 age group were significantly higher than the participants who are over the age of 45. There is a weak-to-medium and positive correlation between the total Mahony Psychological Assessment for Bariatric Surgery total scores and all the subscale and total scores of the Eating Disorder Examination Questionnaire (P < .05 for all). These correlation results support the co-validity of Mahony Psychological Assessment for Bariatric Surgery and Eating Disorder Examination Questionnaire. Internal consistency of the Mahony Psychological Assessment for Bariatric Surgery was at a high level except for the subscale of positive treatment attitude and supportive environment. Cronbach's ɑ values were calculated to be 0.902 for the subscale of emotional and binge eating, 0.820 for the early life problems due to weight, 0.856 for the dysphoric feelings about weight, 0.539 for the positive treatment attitude and supportive environment, and 0.919 for the whole scale.

The analyses have shown that the Turkish version of Mahony Psychological Assessment for Bariatric Surgery may be used in clinical interviews and psychiatric evaluation of bariatric surgery patients in Turkey.
