Matsumoto J, Hirano Y, Numata N, Matzuzawa D, Murano S, Yokote K, Iyo M, Shimizu E, Nakazato M - J Eat Disord (2015)

Bottom Line: Significant negative correlation was found between IGT performance and the BITE symptom subscale in AN.In BN, there was a negative correlation between the EDE-Q weight concerns subscale and IGT performance.Different patterns of association between pathological eating concerns/behaviors and performances in decision-making ability were found between AN, BN, and HC.

ABSTRACT

Background: Decision-making is reported to be impaired in anorexia nervosa (AN) and bulimia nervosa (BN), but the influence of mood status, pathophysiological eating, and weight concerns on the performance of decision-making ability between AN and BN is still unclear. The aims of this study were to investigate differential impairments in the decision-making process between AN, BN, and healthy controls (HC), and secondly, to explore the role of mood status, such as anxiety, depression, pathological eating, and weight concerns, in decision-making ability.

Methods: Patients suffering from AN (n = 22), BN (n = 36) and age-matched HC (n = 51) were assessed for their decision-making abilities using the Iowa Gambling Task (IGT). Self-reported questionnaires including the Eating Disorder Examination Questionnaire (EDE-Q), the Bulimia Investigatory Test, Edinburgh (BITE), the Eating Disorders Inventory, the Maudsley Obsessive-Compulsive Inventory measuring obsessive-compulsive traits, the Hospital Anxiety and Depression Scale, and the Toronto Alexithymia Scale were used to assess pathological eating concerns and attitude to feelings.

Results: Significant differences in IGT performance were observed between BN and HC. Significant negative correlation was found between IGT performance and the BITE symptom subscale in AN. In BN, there was a negative correlation between the EDE-Q weight concerns subscale and IGT performance. It was also found that increased anxiety, depression, and eating/weight concerns predicted poorer decision-making.

Conclusion: Different patterns of association between pathological eating concerns/behaviors and performances in decision-making ability were found between AN, BN, and HC. Anxiety, depressive mood status, and eating/weight concerns were related to decision-making ability.

Scatter plot shows the scores of the third block on IGT (41–60 within 100 trials) and the eating disorder examination questionnaire weight concern subscale (EDE-Qw) for AN, BN, and HC. Negative correlation was found in BN (r = −0.47;p = 0.02).

Fig3: Scatter plot shows the scores of the third block on IGT (41–60 within 100 trials) and the eating disorder examination questionnaire weight concern subscale (EDE-Qw) for AN, BN, and HC. Negative correlation was found in BN (r = −0.47;p = 0.02).

Mentions: We explored correlations among clinical measures including all scores such as TAS-20, EDE-Q, BITE, EDI-2, HADS, MOCI and IGT performance (both IGT total net scores: [C + D]-[A + B](1–100 choices) and block net scores: [C + D]-[A + B](1–20, 21–40, 41–60, 61–80, 81–100) ) in AN and BN females, respectively. Performance in the first block [C + D]-[A + B](1–20) of the IGT was negatively associated with BITE-sas in the AN group (r = −0.73, p = 0.04) (Figure 2). In the BN group, as shown in Figure 3, the IGT performance in the third block [C + D]-[A + B](41–60) was also negatively correlated with EDEQ-w (r = −0.47, p = 0.02). Therefore, we detected different patterns of association between pathological eating concerns/behaviors and the performances of decision-making ability between AN and BN.Figure 2
