RESUMO
High rates of psychiatric symptoms have been reported in pathological gamblers. This study of psychiatric comorbidity in pathological gamblers is the first to use structured psychiatric interviews assessing DSM-III-R Axis I and II disorders. The Structured Clinical Interview for DSM III-R (SCID-P, SCID-II) was administered to 40 (25 male, 15 male) pathological gamblers seeking outpatient treatment in Minnesota for gambling, and 64 (41 male, 23 female) controls. High lifetime rates of Axis I (92%) but not Axis II (25%) psychopathology were found in pathological gamblers as compared to controls. No differences between male and female gamblers were found in rates of affective, substance use or personality disorders. Females had higher rates of anxiety disorders and histories of physical/sexual abuse. Possible associations between psychiatric disorders and pathological gambling are discussed along with gambler typologies and implications for future research.
RESUMO
Little systematic research has been done on psychiatric comorbidity of pathological gambling, an impulse control disorder. This report describes the occurrence of attention deficit disorder and impulse control disorders in 40 pathological gamblers in treatment for gambling problems and 64 controls. Diagnoses were made by structured interviews which utilized operationalized diagnostic criteria. An impulse control disorder other than pathological gambling was noted in 35% of the pathological gamblers, compared to 3% of the controls (p < .001). Compulsive buying (p < .001) and compulsive sexual behavior (p < .05) were significantly higher in pathological gamblers than controls. A strong association was seen among pathological gambling, attention deficit, and other impulse control disorders. Attention deficit disorder was seen in 20% of the pathological gamblers. Rates of impulse control disorders did not differ by gender. Implications of these high rates of comorbidity are discussed.

Eighty-three obese subjects with binge eating disorder (BED) were compared with 99 obese subjects not meeting criteria for BED on the Toronto Alexithymia Scale (TAS). Overall, the subjects in our sample were not significantly alexithymic, the mean global TAS score being 62.8 (SD = 10.2) which is comparable with the values found in non-patient control samples. Furthermore, the mean TAS scores did not differ between obese subjects with and without BED. However, we found a slightly higher prevalence of alexithymia (TAS total score 74 and above) in BED subjects compared with non-BED subjects (24.1% and 11.1%, respectively). A series of stepwise multiple regression analyses were run, exhibiting a significant relationship between the TAS and educational level and the Eating Disorder Inventory (EDI) subscales Interpersonal Distrust and Ineffectiveness. Age, body mass index, measures of depression, and eating pathology did not predict TAS scores.

In this two-part study, an animal model of binge eating was first produced, then the rate of acquisition of cocaine self-administration was assessed. Initially, 16 female weanling rats were food deprived (DEPR) at 25, 95, and 143 days of age. Another group of 16 age-matched controls was allowed ad lib access to food. Each time the DEPR group was food deprived, they were allowed to recover to normal weight. They were then injected with butorphanol tartrate (BUTR), an opioid that stimulates feeding, and food intake was measured for 4 h. All rats given BUTR consumed significantly more food than those given saline. Animals with DEPR history consumed food over a longer period of time, and at h 4 after BUTR injection, they consumed significantly more food than controls. In the second part of the experiment, an autoshaping procedure was used to quantitatively evaluate the rate of acquisition of cocaine self-administration. By day 30, 86% of the DEPR and 69% of the control groups had acquired cocaine self-administration.

One hundred obese women with a mean age of 39.2 years, and a mean body mass index (BMI) of 35.9 kg/m2 were evaluated before entering a treatment study for weight reduction. According to the results of a structured interview, subjects were divided into four groups: (1) no overeating episodes, (2) episodic overeating episodes without the feeling of loss of control, (3) overeating plus the sense of loss of control (binge eating), and (4) full diagnostic criteria for binge eating disorder (BED). One-way analyses of variance (ANOVAs) revealed significant positive associations between binge eating and eating/weight-related characteristics such as a history of frequent weight fluctuations, the amount of time spent dieting, drive for thinness, and a tendency for disinhibition of eating. Furthermore, subjects exhibited more feelings of ineffectiveness, stronger perfectionistic attitudes, more impulsivity, less self-esteem, and less interoceptive awareness the more problems with binge eating they reported. The results support the idea that binge eaters might be a distinct subgroup among the obese population, and corroborate the utility of a diagnosis of BED in identifying the most disturbed obese subjects with regard to the variables tested.

BACKGROUND: Compulsive buying is infrequently described in the psychiatric literature despite suggestions that it may be prevalent. The authors investigated the demographics and phenomenology of this syndrome and assessed psychiatric comorbidity via interviews of both compulsive buyers and normal buyers. METHOD: Twenty-four compulsive buyers were compared with 24 age- and sex-matched normal buyers using (1) a semistructured interview for compulsive buying and impulse control disorders, (2) a modified version of the Structured Clinical Interview for DSM-III-R, and (3) scales measuring compulsiveness, depression, and anxiety. RESULTS: The typical compulsive buyer was a 36-year-old female who had developed compulsive buying at age 17 1/2 and whose buying had resulted in adverse psychosocial consequences. Purchases were usually of clothes, shoes, jewelry, or makeup, which frequently went unused. Compared with normal buyers, compulsive buyers had a higher lifetime prevalence of anxiety disorders, substance use disorders, and eating disorders and were more depressed, anxious, and compulsive. Among compulsive buyers, 16 (66.7%) described buying that resembled obsessive compulsive disorder, whereas 23 (95.8%) described buying that resembled an impulse control disorder. CONCLUSION: Compulsive buying is a definable clinical syndrome that can result in significant psychosocial impairment and which displays features of both obsessive compulsive disorder and the impulse control disorders.

We assessed the correlation between a self-report questionnaire and an expert-rating including an initial interview and a longitudinal evaluation on the diagnosis of binge eating disorder (BED) in a sample of 100 obese women participating in a treatment program for weight reduction. The level of diagnostic agreement between patient-rating and expert-rating with regard to the presence or absence of BED was modest, with a kappa value of .57. According to Shrout, Spitzer, and Fleiss (Archives of General Psychiatry, 44, 172-177, 1987) this represents fair to good agreement beyond chance. The self-report instrument did not produce higher estimates of the frequency of BED in this selected sample of treatment seekers than the expert-rating, as observed in studies on the epidemiology of bulimia nervosa in community samples. The questionnaire identified 40 cases of BED, the expert-rating 43 cases. The results indicate that the disagreement between self-report and interview was mainly due to discordances in three of the diagnostic criteria of BED--namely loss of control, marked distress regarding binge eating, and the frequency requirement of two binge eating episodes per week for a 6-month period. Inconsistencies between subjects and clinicians with regard to the definition of an overeating episode and with regard to the behavioral indicators of loss of control did not lead to differences between self-report and observer-rating in the final diagnosis of BED.

The syndrome of bulimia nervosa has been associated with a high rate of comorbidity with other psychiatric disorders. In particular, high rates of affective disorders, chemical dependency problems, anxiety disorders, and personality disorders have been described among these patients and, in some studies, among their relatives. The reasons for this elevated comorbidity remain unclear. It is frequently difficult to tell which condition develops first. Bulimia nervosa has also been associated with significant medical complications. Most patients with bulimia evidence metabolic and endocrine changes suggestive of a state of semistarvation. Fluid and electrolyte abnormalities are common, as are dental complications. Gastrointestinal complications are rare, but can be quite serious. A careful physical assessment is indicated for each bulimic patient.
