It was hypothesised that the comorbid group will present worse neuropsychological performance that will lead to a worse treatment outcome. Method: The study has a longitudinal design. Women (N = 75) diagnosed with BSD, BSD + CB and Healthy Controls (HC); completed an evaluation of: cognitive flexibility, decision making, eating disorder (ED) symptomatology, psychopathological state and personality traits. Results: BSD + CB was the group with the most severe clinical profile, worst treatment outcome and higher neuropsychological impairment, than other groups. Path-analysis evidenced that deficits in decision making were associated with bad treatment outcome, while deficits in flexibility with the presence of the comorbidity. Self-directedness and novelty seeking were associated with the neuropsychological performance and the comorbidity. Conclusion: BSD + CB exhibit a worse clinical and neuropsychological profile that seems to be related with the treatment outcome, which should be taken into account for the establishment of specific treatment approaches.14 p.application/pdfengcc by (c) Munguía, Lucero et al, 2021http://creativecommons.org/licenses/by/3.0/es/Trastorns de la conducta alimentàriaCompra compulsivaBulimiaCompulsive shoppinginfo:eu-repo/semantics/article7169422021-08-12info:eu-repo/semantics/openAccess
