Decision-making deficits in pathological gambling: the role of executive functions, explicit knowledge and impulsivity in relation to decisions made under ambiguity and risk.

Background: A variety of cognitive and emotional processes influence the decision-making deficits observed in pathological gambling (PG). This study investigated the role of immediate/delayed sensitivity to reward and punishment, executive functions, impulsivity and explicit knowledge in relation to decision-making performance on the original Iowa Gambling Task (IGT-ABCD) and a variant (IGT-EFGH).

Methods: We assessed 131 consecutive patients with a diagnosis of PG by using executive functioning and decision-making tasks, self-report measures of impulsivity and explicit knowledge.

Effect of executive functioning, decision-making and self-reported impulsivity on the treatment outcome of pathologic gambling.

Background: Impairments in self-regulatory behaviour reflect a deficit in executive functioning and decision-making, as well as higher levels of self-reported impulsivity, and may be involved in the development and maintenance of addictive disorders. We sought to explore the association between self-reported impulsivity and neurocognitive measures, and their association with treatment outcome in pathologic gambling.

Methods: We assessed patients with pathologic gambling using executive functioning and decision-making tests and self-report measures of impulsivity.

Subtyping study of a pathological gamblers sample.

Objective: To classify into subgroups a sample of pathological gambling (PG) patients according to personality variables and to describe the subgroups at a clinical level.

Method: PG patients (n = 1171) were assessed with the South Oaks Gambling Screen; the Temperament and Character Inventory-Revised; the Symptom Checklist-90-Revised; Eysenck's Impulsivity Scales, a diagnostic questionnaire for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) PG criteria; and the Structured Clinical Interview for the DSM-IV, Axis I disorders, substance use module. Clinical measures were collected through a semi-structured interview.

Age of onset in pathological gambling: clinical, therapeutic and personality correlates.

We aimed to explore the association between age of onset of gambling problems and current psychopathological and clinical status, personality profile and therapeutic outcome in a sample of pathological gamblers. A total of 904 consecutive pathological gambling patients were administered several instruments about gambling behavior, psychopathology and personality. They received a 4-month cognitive-behavioral group treatment.

Predictors of early change in bulimia nervosa after a brief psychoeducational therapy.

We aimed to examine baseline predictors of treatment response in bulimic patients. 241 seeking-treatment females with bulimia nervosa completed an exhaustive assessment and were referred to a six-session psychoeducational group. Regression analyses of treatment response were performed.

Individual versus group cognitive-behavioral treatment for obsessive-compulsive disorder: a controlled pilot study.

This study sought to examine the effectiveness of group and individual cognitive-behavioral treatment (CBT) and to compare the results with those of a wait-list control group among a sample of patients with obsessive-compulsive disorder (OCD). Fifty-seven individuals diagnosed with OCD were evaluated pre- and posttreatment with the Yale-Brown Obsessive Compulsive Scale and the Hamilton Rating Scales for Anxiety and Depression. Both group and individual CBT obtained statistically significant reductions in anxiety and depressive symptoms.

Comparison of personality risk factors in bulimia nervosa and pathological gambling.

Objective: The objective of the study was to assess the predictive value of personality profiles to classify individuals with bulimia nervosa (BN), pathological gambling (PG), and a nonpsychiatric comparison group while controlling for sex.

Methods: The sample comprised 270 BN (241 women, 29 men), 429 PG (42 women, 387 men), and 96 comparison (nonpsychiatric) subjects (35 women, 61 men). All patients were consecutively admitted to our Psychiatry Department and were diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria.

Exophenotypical profile of adolescents with sustained attention deficit: A 10-year follow-up study.

Unlabelled: We aimed to explore prospectively the relationship between the presence of sustained attention deficit (SAD) in early adolescence and exophenotypical measures of vulnerability to schizophrenia spectrum disorders (personality and psychosocial measures) in early adulthood. Two cohorts of community adolescents were selected in 1993 according to the presence or absence of a CPT-linked SAD. In 2003, both cohorts (Index: n=42, and

Control: n=38) were administered the O-LIFE, the SCID-II, the DOI battery and the COPE scale, among other tests.

Impulse control disorders in eating disorders: clinical and therapeutic implications.

Objective: Few studies have explored impulse control disorders (ICDs) in women with bulimia nervosa (BN). We explored the prevalence of lifetime ICDs in women with BN, compared the severity of eating disorder symptoms in women with BN with and without ICD, and compared their personality profiles to females with one form of ICD, namely, pathologic gambling.

Method: A total sample of 269 female patients consecutively admitted to our unit participated in the current study (173 BN without comorbid ICD [BN - ICD]; 54 BN with comorbid ICD [BN + ICD]; and 42 pathologic gamblers [PG]).
