Gender differences in shame in patients with binge-eating disorder.

OBJECTIVE: To examine the relationship between shame and the behavioral and attitudinal features of eating disorders in men and women diagnosed with binge-eating disorder (BED). RESEARCH METHODS AND PROCEDURES: Participants were 188 consecutively evaluated adults (38 men and 150 women) who met Diagnostic and Statistical Manual of Mental Disorders, 4th edition, criteria for BED. Participants were interviewed and completed a battery of measures assessing shame, behavioral and attitudinal features of eating disorders, and general psychological functioning. RESULTS: Shame did not differ significantly by gender and was not associated with BMI or binge-eating frequency. Shame was significantly associated with the attitudinal features of eating disorders, even after controlling for levels of depression and self-esteem. When considered separately by gender and controlling for depression and self-esteem, shame was associated with body dissatisfaction in men and with weight concern in women. DISCUSSION: Men and women with BED, who presented for treatment, reported similar levels of shame. Overall, while shame was related to attitudinal features, the specific associations differed by gender. For men, shame was related to how dissatisfied they felt with their bodies, whereas for women, shame was associated with concerns about weight. Interestingly, shame was not related to BMI or binge-eating frequency in men or women. These results provide preliminary support for self-conscious emotions playing different roles in men and women with BED.

Correlates of suicide risk in juvenile detainees and adolescent inpatients.

OBJECTIVE: To compare correlates of risk for suicidal behavior in juvenile detainees with those in another high-risk group, adolescent psychiatric inpatients. METHOD: Eighty-one adolescents in a short-term juvenile detention center were contrasted with a matched group of 81 adolescent psychiatric inpatients on a clinical assessment battery of established instruments including a measure for risk of suicidal behavior. RESULTS: Juvenile detainees and adolescent psychiatric inpatients reported similar levels of distress on measures of suicide risk, depression, impulsivity, and drug abuse. After controlling for depression, impulsivity and drug abuse remained significantly associated with suicide risk scores in the juvenile detention group, but did not in the psychiatric contrast group. For depressed female inpatients, hopelessness added significantly to the prediction of suicide risk scores. CONCLUSIONS: Correlates of risk for suicidal behavior in juvenile detainees may differ from those in other high-risk groups. Results suggest that it may be helpful to examine impulsivity and history of drug abuse when assessing suicide risk for detained adolescents. Further study of juvenile detainees as a separate high-risk group is warranted to better determine the nature and extent of risk.

Childhood antecedents of avoidant personality disorder: a retrospective study.

OBJECTIVE: To explore potential risk factors and early manifestations of avoidant personality disorder (AVPD) by examining retrospective reports of social functioning and adverse childhood experiences. METHOD: Early social functioning and pathological childhood experiences were assessed using the Childhood Experiences Questionnaire-Revised. The responses of 146 adults diagnosed with primary AVPD were compared with a group of 371 patients with other personality disorders as a primary diagnosis and a group of 83 patients with current major depression disorder and no personality disorders, using chi2 analyses. Diagnoses were based on semistructured interviews by trained reliable clinicians. RESULTS: Adults with AVPD reported poorer child and adolescent athletic performance, less involvement in hobbies during adolescence, and less adolescent popularity than the depressed comparison group and the other personality disorder group. Reported rates of physical and emotional abuse were higher than the depressed group, but this result was influenced by comorbid diagnoses. CONCLUSIONS: These results suggest that early manifestations of AVPD are present in childhood but that various forms of abuse are not specific to the disorder.

Salivary cortisol responses to dexamethasone in adolescents with posttraumatic stress disorder.

OBJECTIVE: Previous studies of adults with posttraumatic stress disorder (PTSD) have found various abnormalities in the regulation of the hypothalamic-pituitary-adrenal axis, including enhanced suppression of cortisol following low-dose dexamethasone. The purpose of the present study was to investigate salivary cortisol responses to low-dose dexamethasone in adolescents with PTSD. METHOD: Forty-eight adolescents (20 with current PTSD, 9 trauma controls without PTSD, and 19 healthy nontraumatized controls) were enrolled in the study. On day 1, baseline saliva samples were obtained at 8 a.m. and 0.5 mg of dexamethasone was administered at 11 p.m. Cortisol and dexamethasone levels were assessed at 8 a.m. the following day. RESULTS: Adolescents with current PTSD showed no difference in the suppression of salivary cortisol in response to low-dose (0.5 mg) dexamethasone compared to trauma controls without PTSD and nontraumatized controls. More severely affected PTSD subjects with co-occurring major depression showed higher pre- and post-dexamethasone salivary cortisol levels compared to controls. CONCLUSIONS: The present study did not find evidence for enhanced suppression of salivary cortisol at 8 a.m. following low-dose dexamethasone in multiply traumatized adolescents with PTSD. This result differs from findings in adults with PTSD. Further investigations of hypothalamic-pituitary-adrenal axis abnormalities in traumatized children and adolescents are needed.

Comparison of patients with bulimia nervosa, obese patients with binge eating disorder, and nonobese patients with binge eating disorder.

This study compared patients with bulimia nervosa (BN), obese patients with binge eating disorder (BED), and nonobese patients with BED. One hundred sixty-two adult women consecutively evaluated for outpatient clinical trials who met DSM-IV criteria for BN, purging type (N = 46) or for BED (N = 79 obese and N = 37 nonobese) were compared using the Eating Disorder Inventory (EDI). The three groups differed significantly on two (drive for thinness and body dissatisfaction) of the three eating-related scales and on all five of the general personality scales of the EDI. When age and depression level were controlled, findings for the eating-related scales did not change, whereas four of the five general personality scales were no longer significant. Post hoc analyses revealed that the BN group and the nonobese BED group had significantly higher drive for thinness than the obese BED group. The nonobese and the obese BED groups did not differ from each other in any area (other than drive for thinness), including body dissatisfaction. The nonobese and the obese BED groups had significantly lower maturity features than the BN group. Our findings suggest that when the effects of age and depression levels are controlled, treatment-seeking women with BN and BED are generally similar. Certain differences that do exist between women with BN and BED are associated with obesity status (drive for thinness), whereas others are associated with diagnosis (body dissatisfaction, maturity fears).

Clinical features and impairment in women with Borderline Personality Disorder (BPD) with Posttraumatic Stress Disorder (PTSD), BPD without PTSD, and other personality disorders with PTSD.

The aims of this study were to examine differences in clinical features, impairment, and types of childhood traumas among women with borderline personality disorder (BPD), women with BPD and posttraumatic stress disorder (PTSD), and those with other personality disorders and PTSD. Using baseline data from the Collaborative Longitudinal Study of Personality Disorders, 186 women were divided into 3 groups (BPD+PTSD, BPD, PTSD), based on structured diagnostic interviews for Axis I and Axis II disorders and compared on selected clinical variables. The additional diagnosis of PTSD in borderline women did not significantly increase the degree of borderline pathology and psychiatric morbidity but did significantly increase general dysfunction and the occurrence of hospitalization. The additional diagnosis of BPD in women with PTSD significantly increased the features of suicide proneness and impulsiveness. Both groups of women with PTSD reported significantly more types of childhood traumas relative to borderline women without PTSD. Consistent with other research, the findings suggest that PTSD does not appear to alter the central features of BPD. The clinical implications of our findings are considered.

On the relation of flexible and rigid control of eating to body mass index and overeating in patients with binge eating disorder.

OBJECTIVE: To examine the relationship of flexible and rigid dimensions of restrained eating to body mass index (BMI) and overeating in outpatients with binge eating disorder (BED). METHOD: Participants were 148 consecutive outpatients who met criteria for BED. The Three-Factor Eating Questionnaire (TFEQ) was administered to assess Cognitive Restraint, Hunger, and Disinhibition. The TFEQ also contains two Cognitive Restraint subscales--Flexible Control and Rigid Control. The Eating Disorder Examination-Questionnaire version (EDE-Q) was administered to assess frequency of different forms of overeating during the past 28 days and the attitudinal features of eating disorders. RESULTS: Flexible Control and Rigid Control were significantly correlated with each other. They were both negatively correlated with BMI, but neither was significantly correlated with the frequency of binge eating or other forms of overeating. In addition, Flexible Control and Rigid Control predicted almost the same amount of variance in BMI. DISCUSSION: BED patients exhibit flexible and rigid control of eating that is related to BMI, but not to the frequency of binge eating or other forms of overeating. Results of the present study provide preliminary evidence that flexible and rigid control of eating may not be a useful distinction in BED patients. However, increased restraint, regardless of type, may prove to be of benefit with regard to weight control and may not have adverse effects on binge eating in obese BED patients.

Eating and body image disturbances in adolescent psychiatric inpatients: gender and ethnicity patterns.

OBJECTIVE: To examine gender and ethnicity patterns in eating and body image disturbances in adolescents hospitalized in a psychiatric facility. METHOD: Participants comprised 715 inpatients who completed the Millon Adolescent Clinical Inventory. Gender (317 males, 398 females), ethnicity (553 Caucasians, 77 Latinõ Americans, 85 African Americans), and Gender x Ethnicity interactions in the features of eating disorders and body image disturbance were explored in the study group. RESULTS: Eating-related disturbances at diagnostic threshold were infrequent but participants' reported rates of specific features and symptoms were not. Overall, a significantly higher proportion of females than males reported features of eating and body image disturbances. The three ethnic groups differed significantly in their reports of body image disturbances but not in their endorsement of features of eating disorders. Post-hoc comparisons revealed that a significantly higher proportion of Caucasian participants reported body image concerns than did African American and Latinõ American participants who did not differ significantly from one another. Significant Gender x Ethnicity interactions were observed, with Caucasian females endorsing higher rates of features of eating disorders and body image disturbances than African American and Latinõ American females. DISCUSSION: In adolescent psychiatric inpatients, although Caucasian females report the highest rates of the features of eating and body image disturbances, such concerns are not uncommon in males and in minorities.

Gender differences in patients with binge eating disorder.

OBJECTIVE: This study examined gender differences in patients with binge eating disorder (BED). METHOD: Participants were 182 adults (35 male, 147 female) who were consecutively evaluated for outpatient clinical trials and met criteria for BED as outlined in the 4th ed. of the Diagnostic and Statistical Manual of Mental Disorders. They were administered a battery of measures to examine developmental, eating and weight-related disturbances, and psychological features associated with BED. RESULTS: Men and women did not differ significantly on several developmental variables (age at first overweight, age at first diet, age at onset of regular binge eating, or number of weight cycles). Men had significantly higher current body mass index (BMI), highest adult BMI, and were significantly more likely to be classified as obese. Men and women did not differ significantly on measures of current eating disorder features (binge eating, eating concerns, weight or shape concerns) but women reported significantly greater body image dissatisfaction and drive for thinness. Men and women did not differ significantly on current depression or self-esteem but men reported a greater frequency of past drug abuse problems. DISCUSSION: Although men and women who present for treatment for BED show many similarities in current eating disorder features, we observed a number of gender differences on important developmental and physical variables as well as associated psychological features.

Recent research of relationships among eating disorders and personality disorders.

This review focuses on recent research examining the relationships among eating disorders (ED) and personality disorders (PD). Studies that have examined rates of PD in patients with ED and rates of ED in patients with PD have generally reported high rates of diagnostic co-occurrence, although the marked inconsistency and variability in rates across studies is striking. Methodologic limitations and conceptual problems make interpretation of the existing literature ambiguous. Overall, circumspect review suggests that anorexia nervosa may be associated with obsessional and perfectionistic forms of personality disturbances, bulimia nervosa with impulsive and unstable personality disturbances, and binge eating disorder with avoidant and anxious forms of personality disturbances. In terms of longitudinal associations, PD may be more closely associated with the course of general psychiatric or psychosocial functioning than with fluctuations in the course of ED. The significance (and more precise nature) of these associations, however, is unclear and will require sophisticated longitudinal studies to arrive at more definitive answers.

Confirmatory factor analysis of DSM-IV borderline, schizotypal, avoidant and obsessive-compulsive personality disorders: findings from the Collaborative Longitudinal Personality Disorders Study.

OBJECTIVE: To test the diagnostic constructs implied by DSM-IV Axis-II personality disorders by examining relationships between different combinations of DSM-IV criteria. METHOD: Confirmatory factor analysis was used to test the borderline, schizotypal, avoidant and obsessive-compulsive personality disorder constructs in a large treatment-seeking sample (N= 668) from a multisite study. A model based on the three DSM-IV Axis II clusters was also tested. Both models were tested against a unitary 'generic' model constructed from four criteria sets combined. RESULTS: Goodness-of-fit for both the three-cluster and four disorder models was significantly better than the unidimensional model, and the four-disorder model was significantly better than the three-cluster model. Results were replicated using data from 2-year follow-up obtained by interviewers blind to original Axis II diagnoses at baseline. CONCLUSION: Support is provided for the DSM-IV disorder-level classification for schizotypal, borderline, avoidant and obsessive-compulsive personality disorders in a treatment-seeking sample.

Weight loss expectations in patients with binge-eating disorder.

OBJECTIVE: To study weight loss expectations in patients with binge-eating disorder and to examine whether expectations differed by sex and motivation for treatment. RESEARCH METHODS AND PROCEDURES: One hundred and thirty patients (104 women and 26 men), aged 23 to 61 (mean age, 43.0 years), with BED completed a measure of desired weights that included their dream weight, happy weight, acceptable weight, and disappointed weight. In a structured interview, participants were asked their primary motivation for seeking treatment (appearance or health) and their lowest adult weight (LAW). RESULTS: The BED participants reported weight loss expectations that far exceeded expert and governmental guidelines. In this sample, desired dream body mass index (BMI), happy BMI, and acceptable BMI averaged reductions in current weight of 36%, 29%, and 23%, respectively. Even the "disappointed" BMI was an average 14% reduction in current weight, and was 1.5 to 3 times greater than the expert recommendation (5% to 10%). Comparisons of desired weights were significantly different for women and men, whereas percent reductions from current weight were not. Although weight goal expectations were significantly lower for those motivated by appearance, compared with those motivated by health, percent reductions for current weight were not. Desired dream weight correlated with reported LAW, and the mean difference between these weights was not significant. DISCUSSION: These findings suggest that patients with BED have weight loss expectations that far exceed expert and governmental guidelines and that these expectations do not differ by sex or motivation for seeking treatment. One possible explanation for these unrealistic desired weights may be the patients' recollections of their LAWs.

Cultural, psychological, and demographic correlates of willingness to use psychological services among East Asian immigrants.

To assess East Asian immigrants' willingness to use psychological services if depressed and willingness to recommend psychological services to distressed friends, and to examine their cultural (acculturation status, self-construal, ethnic identity), psychological, and demographic correlates, 170 East Asian immigrants (88 male, 82 female) were administered a battery of psychometrically established measures. Approximately 50% of participants expressed strong unwillingness to seek psychological treatments, and approximately 30% expressed strong unwillingness to recommend such treatments to distressed friends. Personal willingness to use psychological services was positively associated with assimilation, being female, age, and English fluency, but was negatively associated with interpersonal distance and number of years in the United States. In contrast, willingness to recommend psychological services to friends was positively associated with independent self-construal, overall ethnic identity, interpersonal sensitivity, being female, and number of years in the United States but was negatively associated with interpersonal distance and reported obsessive-compulsive symptoms. A minority of East Asian immigrants report being willing to seek or to recommend psychological services. Psychological distress, and cultural and demographic features were differentially associated with willingness to seek versus willingness to recommend psychological services.

DSM-IV axis II comorbidity with borderline personality disorder in monolingual Hispanic psychiatric outpatients.

The authors examined the comorbidity of DSM-IV borderline personality disorder (BPD) with other personality disorders (PD) in a series of adult monolingual (Spanish only) Hispanic psychiatric outpatients with substance use disorders. One hundred outpatients (69 men and 31 women) were assessed with the Spanish version of the Diagnostic Interview for DSM-IV Personality Disorders. PD co-occurrence in the group of patients with BPD (N = 34) was statistically compared with that in the group without BPD (N = 66). Bonferroni-corrected chi-square analysis showed significant diagnostic comorbidity with BPD for antisocial, avoidant, and depressive PD. However, analyses conducted separately by gender showed no significant comorbidity of any PD with BPD in women and significant comorbidity with antisocial, avoidant, and depressive PD in men. These results suggest that in monolingual Hispanic psychiatric outpatients with substance use disorders, gender may play a role in the nature of BPD comorbidity. The BPD diagnosis may represent a broader range of psychopathology in Hispanic men than women.

Traumatic exposure and posttraumatic stress disorder in borderline, schizotypal, avoidant, and obsessive-compulsive personality disorders: findings from the collaborative longitudinal personality disorders study.

The association between trauma and personality disorders (PDs), while receiving much attention and debate, has not been comprehensively examined for multiple types of trauma and PDs. The authors examined data from a multisite study of four PD groups: schizotypal, borderline (BPD), avoidant, and obsessive-compulsive, and a major depression comparison group. Rates of traumatic exposure to specific types of trauma, age of first trauma onset, and rates of posttraumatic stress disorder are compared. Results indicate that BPD participants reported the highest rate of traumatic exposure (particularly to sexual traumas, including childhood sexual abuse), the highest rate of posttraumatic stress disorder, and youngest age of first traumatic event. Those with the more severe PDs (schizotypal, BPD) reported more types of traumatic exposure and higher rates of being physically attacked (childhood and adult) when compared to other groups. These results suggest a specific relationship between BPD and sexual trauma (childhood and adult) that does not exist among other PDs. In addition, they support an association between severity of PD and severity of traumatic exposure, as indicated by earlier trauma onset, trauma of an assaultive and personal nature, and more types of traumatic events.

Short-term diagnostic stability of schizotypal, borderline, avoidant, and obsessive-compulsive personality disorders.

OBJECTIVE: Personality disorders are defined as enduring patterns of maladaptive behaviors and traits that are stable over time. This study prospectively examined the stability of four personality disorders (schizotypal, borderline, avoidant, and obsessive-compulsive) over a 1-year follow-up period. METHOD: Subjects (N=668) were recruited from multiple clinical settings at four collaborating institutions. Subjects met criteria for one or more of the four personality disorders or were part of a comparison group of subjects with major depressive disorder and no personality disorder. Diagnoses were established by using semistructured interviews. Follow-up assessments, conducted 6 and 12 months after the baseline assessment, included monthly ratings of all criteria for the four personality disorders and weekly ratings of the course of major depressive disorder. The current report is based on 621 subjects with complete data through 12 months of the follow-up period. RESULTS: Significantly more subjects in each personality disorder group remained at diagnostic threshold throughout the 12 months of the follow-up period than did those in the major depressive disorder group. A continuous measure of number of criteria met was highly correlated across the three assessments. The majority of personality disorder subjects, however, did not consistently remain at diagnostic threshold, and the mean number of criteria met decreased significantly for each group. CONCLUSIONS: Individual differences in personality disorder features appear to be highly stable, although the number of criteria present decreases over time. Personality disorders may be characterized by stable trait constellations that fluctuate in degree of maladaptive expression.

Diagnostic efficiency of borderline personality disorder criteria in hospitalized adolescents: comparison with hospitalized adults.

OBJECTIVE: The authors examined the diagnostic efficiency of borderline personality disorder criteria in adolescent inpatients. For comparison, diagnostic efficiency of borderline personality disorder criteria was also examined in a group of concurrently recruited adult inpatients. METHOD: Adolescents (N=123) and adults (N=106) were reliably assessed with the Personality Disorder Examination, a semistructured diagnostic interview for DSM-III-R personality disorders. Sixty-five adolescents and 50 adults met diagnostic criteria for borderline personality disorder. Conditional probabilities were calculated to determine which borderline personality disorder criteria were most efficient as inclusion criteria and as exclusion criteria. Adolescents and adults were analyzed separately, and the results were compared. RESULTS: There were no significant differences between groups with regard to the base rates of the borderline personality disorder diagnosis nor for any borderline personality disorder criterion. The best inclusion criterion for the adolescents was abandonment fears, though for the adults all symptoms were approximately equivalent in this regard. The most efficient exclusion criterion was uncontrolled anger for the adolescents and impulsiveness for the adults. CONCLUSIONS: In hospitalized patients, borderline personality disorder and its symptoms appear to be as frequent for adolescents as for adults. Despite these surface similarities between groups with respect to symptom patterns, several differences were found at the level of the diagnostic efficiency for individual borderline personality disorder criteria. These differences may shed light on the nature of borderline psychopathology during adolescence.
