Abstract: Dimensional theoretical models suggest that gambling disorder and eating disorders have two essential shared risk factors: impulsivity and compulsivity. In order to delve into the association between these factors, the main objectives of this thesis were: To study the interaction between different types of impulsivity in gambling and eating disorders. To evaluate the association between impulsivity and DSM-5 criteria used for the diagnosis of gambling disorder, the criterion of illegal acts and the three levels of severity of the disorder. To examine dimensions of compulsivity and the interaction between them and impulsivity levels in the specific case of the gambling disorder. The following conclusions can be drawn: 1) Clinical heterogeneity has been observed, especially taking into account impulsivity levels, between patients with anorexia nervosa of the restrictive subtype and anorexia nervosa of the binge eating/purge subtype. Therefore, the importance of separating the two subtypes of anorexia nervosa is confirmed. 2) Impulsivity and compulsivity can be considered two independent domains in gambling disorder, supporting the dimensional perspective of the impulsive-compulsive spectrum. 3) The multifactorial nature of both domains has been tested. 4) Impulsivity and compulsivity do not contribute to gambling disorder equitably, and impulsivity is more strongly associated with the disorder. 5) All dimensions of impulsivity seem to be interrelated. 6) An association between choice and trait impulsivity has been observed in young patients, corroborating that age is a key factor. 7) Response impulsivity is not significantly associated with the severity of gambling disorder. 8) There is a proven association between impulsivity, gambling disorder, and the commission of criminal acts related to gambling behavior. 9) Impulsive traits may be related to response to treatment for gambling disorder. 10) It was not possible to demonstrate that greater severity was associated with better treatment response, which would question the clinical applicability of DSM-5 criteria.
