Remission from pathological gambling among Hispanics and Native Americans.

This community survey studied remission from pathological gambling (PG) among American Indian (AI) and Hispanic American (HA) veterans. Remission was defined as having a lifetime diagnosis of PG, but no gambling symptoms in the last year. Sample consisted of 1624 AI and Hispanic veterans. Instruments included demographic data, the computer-based algorithmic Quick Diagnostic Interview Schedule Symptom, and three symptom checklists, one each for substance related problems (MAST/AD), anxiety and depressive symptoms (BSI-57), and combat-related post-trauma symptoms (PCL/M). Remission was associated with absence of a current Axis 1 diagnosis, especially absence of a current post-traumatic stress disorder.

Use of extreme weight control behaviors with and without binge eating in a community sample: implications for the classification of bulimic-type eating disorders.

OBJECTIVE AND METHOD: To inform the classification of bulimic-type eating disorders not meeting formal diagnostic criteria for bulimia nervosa (BN), levels of eating disorder psychopathology and functional impairment associated with subjective and objective bulimic episodes (SBEs and OBEs) and purging and nonpurging methods of weight control were examined in a large community-based sample of women (n = 5,232). RESULTS: Participants who reported recurrent bulimic episodes had significantly higher levels of eating disorder psychopathology and functional impairment than those who did not and this was the case whether the episodes were objective or subjective. Similarly, participants who reported the use of extreme weight control behaviors had higher levels of eating disorder psychopathology and functional impairment than those who did not, and this was the case whether purging or nonpurging behaviors were employed. The combination of bulimic episodes and extreme weight control behaviors was associated with particularly high levels of eating disorder psychopathology and functional impairment. CONCLUSION: The combination of bulimic episodes, objective or subjective, and extreme weight control behaviors, purging or nonpurging, is significant in terms of impairment in psychosocial functioning among individuals affected by eating disorders not meeting formal diagnostic criteria for BN. The combination of SBEs and extreme weight control behaviors, in particular, warrants further investigation.

Is multi-impulsive bulimia a distinct type of bulimia nervosa: Psychopathology and EMA findings.

OBJECTIVE: To determine if clinically defined multi-impulsive bulimia (MIB) can be validated using an empirical classification approach. METHOD: One hundred and twenty-five women who met DSM-IV criteria for bulimia nervosa were interviewed and completed a two-week EMA protocol. Participants who reported at least three highly impulsive behaviors were compared to participants who did not report such impulsive behavior. Also, Latent Class Analysis (LCA) was conducted to determine if the MIB classification could be replicated empirically. RESULTS: LCA produced a two-class solution consistent with the traditional clinical approach to MIB classification. In both approaches, MIB was associated with higher levels of anxiety disorders, child abuse, and daily self-damaging behaviors than the non-MIB class. CONCLUSION: Clinical classification of MIB was empirically supported through LCA. Although the classes failed to differ in bulimic behavior, MIB appears to represent a group of bulimic individuals with significant trauma histories and associated psychopathology.

Eating disorders and personality: a methodological and empirical review.

Methodological approaches utilized to evaluate models of the relationship between personality and eating disorders, as well as empirical support for each model, are reviewed. Limited prospective research suggests that negative emotionality, perfectionism, drive for thinness, poor interoceptive awareness, ineffectiveness, and obsessive-compulsive personality traits are likely predisposing factors. Limited family study research suggests that obsessive-compulsive personality disorder (OCPD) and anorexia nervosa share a common familial liability. Potential pathoplastic personality factors include Cluster B personality disorders and OCPD, which predict a poorer course and/or outcome, and histrionic personality traits and self-directedness, which predict a more favorable course and/or outcome. Future research should focus upon sophisticated prospective and family study research in order to best evaluate competing models of the eating disorder-personality relationship.

Sweet intake, sweet-liking, urges to eat, and weight change: relationship to alcohol dependence and abstinence.

INTRODUCTION: Linkages between alcohol dependence (AD) and abstinence and aspects of food ingestion and preference have been described in animals and humans, including (1) eating sweets decreases urges to drink alcohol; (2) preferences for highly sweet tastants is associated with alcohol dependence; and (3) food deprivation leads to increased alcohol intake. METHODS: We randomly assigned AD subjects in early abstinence to 3 different sets of dietary instructions (eat sweets for alcohol urges; eat a balanced diet; avoid sweets). We compared the groups on urges for alcohol, alcohol consumption, weight, and sweet preference at baseline, one, and six months. We also compared these AD subjects with light-drinking C's and compared AD subjects who remained abstinent for 6 month follow-up with nonabstinent AD subjects. RESULTS: Recruited AS subjects, 38 of 68, completed 6 month follow-up; 27 of 36 C's completed the follow-up. 21 AD's were abstinent while 17 were non-abstinent. There was no effect of dietary recommendations on urges to drink or alcohol consumption. AD's were more likely than C's to prefer highly sweet tastants. The proportion of AD's preferring the sweetest tastant decreased over time. AD's gained more weight than C's over the 6-month follow-up. DISCUSSION: While the use of sweets did not affect urges to drink or drinking, important relationships between sweet preference, weight gain, and alcohol dependence or abstinence were identified.

An investigation of tic suppression and the rebound effect in Tourette's disorder.

Many patients, parents of children with Tourette's disorder, and professionals have suggested that following a period of suppression, tics will rebound to a rate that will exceed the average rate of occurrence. At present, there are no empirical data to support or refute such an effect. This experiment utilized an A-B-A design with replication to test this hypothesized effect. Following baseline observation, participants were instructed to refrain from exhibiting tics while watching videotapes, engaging in conversation, or while alone in a room with no activity. Observation continued following the suppression phase. Results of this experiment showed suppression of tics in almost one half of all sessions, with adults demonstrating suppression more frequently. Furthermore, results of this experiment failed to support a commonly held perception that following a period of voluntary suppression tics will rebound to a rate that will exceed the average rate of occurrence.

Gender, ethnicity, self-esteem and disordered eating among college athletes.

OBJECTIVE: This study was undertaken to compare ethnic and gender differences regarding self-esteem and various disordered eating attitudes and behaviors among elite college athletes. METHOD: A total of 1445 student athletes from 11 Division I schools were surveyed using a 133-item questionnaire. RESULTS: White female athletes reported significantly lower self-esteem than Black female, Black male and White male athletes. Black female athletes' self-esteem was equal to both Black and White male athletes. White female athletes reported significantly higher drive for thinness, body dissatisfaction, and more disturbed eating behaviors than Black female and both groups of male athletes. DISCUSSION: The current study demonstrates that White female athletes appear to be most at risk for having difficulty with eating disorders. Their reporting of significantly lower self-esteem indicates that this may be a risk factor that is more characteristic of this ethnic group. Questions are raised about what factors exist in the Black female culture that protect them from low self-esteem and disordered eating attitudes and behaviors.

Direct and retrospective assessment of factors contributing to compulsive buying.

Compulsive buying is a disorder that has begun to receive attention from researchers in recent years. The results of a handful of studies suggest that compulsive buying occurs in response to negative emotions and results in a decrease in the intensity of the negative emotions. In this investigation, we used interview and self-monitoring methods to evaluate the antecedents and consequences of compulsive buying in a sample of women who met criteria for compulsive buying on the compulsive buying scale (J. Consumer Res. 19 (1992) 459). As a group, the participants reported negative emotions as the most common antecedents to compulsive buying, and euphoria or relief from the negative emotions as the most common consequence of compulsive buying. These findings were consistent across the interview and self-monitoring assessment methods. The implications for assessment and treatment are discussed.

Dental practitioners and eating disorders.

To better understand how dental practitioners identify, counsel, and refer patients with eating disorders. A questionnaire was mailed to 625 dental practitioners, 54 (19%) of the dentists and 69 (20%) of the dental hygienists responded. Most dental practitioners were aware of eating disorder patients in their practices and most discussed their findings with their patients or parents. However, one of the suggestions most commonly given to patients, to brush immediately after vomiting, may be counter therapeutic, and a few offered referral for more health services. Collaboration between dental practitioners and mental health practitioners who work with eating disorder patients should be improved.

An evaluation of affect and binge eating.

The affect regulation model of binge eating suggests that binge eating occurs because it provides momentary relief from negative affect. The purpose of this study was to evaluate change in affect during binge eating to evaluate the merits of this model. Participants were young adult women from a midwestern university. Binge eaters recorded their level of pleasantness using the affect grid at 2-minute intervals before, during, and after binge eating episodes and regular meals. Controls recorded in a similar manner during meals. The results showed a different pattern of affect for binge eaters during binge eating episodes and normal meals and for binge eaters and controls at normal meals. The results support the affect regulation model of binge eating and suggest that binge eating is negatively reinforced because it produces momentary relief from negative affect.

The relationship between compulsive buying and eating disorders.

OBJECTIVE: Compulsive buying has received increased research attention in the last decade. The disorder has high rates of comorbidity for other disorders, including eating disorders. This study explored the possible relationship between compulsive buying and eating disorders. METHOD: Twenty women who scored in the pathological range on a measure of compulsive buying and 20 controls were recruited via the media. Various measures of psychopathology and eating disorder symptoms were administered to both groups. RESULT: Compulsive buyers were significantly more likely to have a higher lifetime history of substance abuse or dependence. No differences existed between normal controls and compulsive buyers in prevalence of current or lifetime eating disorders, nor were there differences in scores of eating-related psychopathology. DISCUSSION: This work failed to demonstrate an increased risk for eating disorder in compulsive buyers, although a higher rate of substance dependence or abuse and higher scores on pathological personality dimension scales were seen.

Self-harm and bulimia nervosa: a complex connection.

There is some evidence to suggest that eating disordered individuals are unusually likely to engage in self-harm behavior. However, the nature of the relationship among self-harm, bulimia nervosa, and related constructs such as borderline personality disorder and multi-impulsive bulimia nervosa remains unclear. This article briefly addresses the nature of this relationship and discusses two possible mechanisms for self-harm behavior in bulimia nervosa. Additionally, a protocol for managing such behavior in the treatment of eating disordered individuals is presented.
