What predicts suicide attempts in women with eating disorders?

BACKGROUND: Suicide is a common cause of death in anorexia nervosa and suicide attempts occur often in both anorexia nervosa and bulimia nervosa. No studies have examined predictors of suicide attempts in a longitudinal study of eating disorders with frequent follow-up intervals. The objective of this study was to determine predictors of serious suicide attempts in women with eating disorders. METHOD: In a prospective longitudinal study, women diagnosed with either DSM-IV anorexia nervosa (n = 136) or bulimia nervosa (n = 110) were interviewed and assessed for suicide attempts and suicidal intent every 6-12 months over 8.6 years. RESULTS: Fifteen percent of subjects reported at least one prospective suicide attempt over the course of the study. Significantly more anorexic (22.1%) than bulimic subjects (10.9%) made a suicide attempt. Multivariate analyses indicated that the unique predictors of suicide attempts for anorexia nervosa included the severity of both depressive symptoms and drug use over the course of the study. For bulimia nervosa, a history of drug use disorder at intake and the use of laxatives during the study significantly predicted suicide attempts. CONCLUSIONS: Women with anorexia nervosa or bulimia nervosa are at considerable risk to attempt suicide. Clinicians should be aware of this risk, particularly in anorexic patients with substantial co-morbidity.

Preservation of neuroendocrine control of reproductive function despite severe undernutrition.

Anorexia nervosa (AN) is characterized by low weight and self-imposed caloric restriction and leads to severe bone loss. Although amenorrhea due to acquired GnRH deficiency is nearly universal in AN, a subset of patients maintains menses despite low weight. The mechanisms underlying continued GnRH secretion despite low weight in these patients and the impact of gonadal hormone secretion on bone mineral density (BMD) in such eumenorrheic, low-weight patients remain unknown. We hypothesized that 1) eumenorrheic women with AN would have higher body fat and levels of nutritionally dependent hormones, including leptin and IGF-I, than amenorrheic women with AN and comparable body mass index; and 2) BMD would be higher in these women. We also investigated whether the severity of eating disorder symptomatology differed between the groups. We studied 116 women: 1) 42 low-weight women who fulfilled all Diagnostic and Statistical Manual of Mental Disorders (fourth edition) diagnostic criteria for AN, except for amenorrhea; and 2) 74 women with AN and amenorrhea for at least 3 months. The two groups were similar in body mass index (17.1 +/- 0.2 vs. 16.8 +/- 0.2 kg/m(2)), percent ideal body weight (78.2 +/- 0.8% vs. 76.7 +/- 0.8%), duration of eating disorder (70 +/- 13 vs. 59 +/- 9 months), age of menarche (13.2 +/- 0.3 vs. 13.5 +/- 0.2 yr), and exercise (4.5 +/- 1.0 vs. 4.2 +/- 0.5 h/wk). As expected, eumenorrheic patients had a higher mean estradiol level (186.6 +/- 19.0 vs. 59.4 +/- 2.5 nmol/liter; P < 0.0001) than amenorrheic subjects. Mean percent body fat, total body fat mass, and truncal fat were higher in eumenorrheic than amenorrheic patients [20.9 +/- 0.9% vs. 16.7 +/- 0.6% (P = 0.0001); 9.8 +/- 0.5 vs. 7.8 +/- 0.3 kg (P = 0.0009); 3.4 +/- 0.2 vs. 2.7 +/- 0.1 kg (P = 0.006)]. The mean leptin level was higher in the eumenorrheic compared with the amenorrheic group (3.7 +/- 0.3 vs. 2.8 +/- 0.2 ng/ml; P = 0.04). Serum IGF-I levels were also higher in the eumenorrheic than in the amenorrheic group (41.8 +/- 3.7 vs. 30.8 +/- 2.3 nmol/liter; P = 0.02). There were only minor differences in severity of eating disorder symptomatology, as measured by the Eating Disorders Inventory, and where differences were observed, eumenorrheic subjects manifested more severe symptomatology than amenorrheic subjects. Mean BMD at the posterior-anterior and lateral spine were low in both groups, but were higher in patients with eumenorrhea than in those with amenorrhea [posterior-anterior spine T-score, -0.9 +/- 0.1 vs. -1.9 +/- 0.1 (P < 0.0001); lateral spine T-score, -1.2 +/- 0.1 vs. -2.3 +/- 0.2 (P < 0.0001)]. In contrast, preservation of menstrual function was not protective at the total hip (total hip T-score, -0.9 +/- 0.1 vs. -1.1 +/- 0.1; P = 0.27), trochanter, or femoral neck. In summary, patients with eumenorrhea had more body fat and higher serum leptin levels than their amenorrheic counterparts of similar weight. Moreover, reduced bone density was observed in both groups, but was less severe at the spine, but not the hip, in women with undernutrition and preserved menstrual function than in amenorrheic women of similar weight. Therefore, fat mass may be important for preservation of normal menstrual function in severely undernourished women, and this may be in part mediated through leptin secretion. In addition, nutritional intake and normal hormonal function may be independent contributors to maintenance of trabecular bone mass in low-weight women.

Pregnancy complications and neonatal outcomes in women with eating disorders.

OBJECTIVE: This study reported pregnancy complications and neonatal outcomes for 49 live births in a group of women with eating disorders who were prospectively followed. METHOD: Subjects were recruited from 246 women participating in a longitudinal study of anorexia nervosa and bulimia nervosa, now in its 12th year. Subjects were interviewed by trained assistants and completed a brief self-report instrument that assessed both birth statistics and birth-related complications. Medical records and/or self-report data describing the neonates' birth status were obtained. RESULTS: The majority of the women with eating disorders had normal pregnancies, resulting in healthy babies. Across the group, the mean length of pregnancy was 38.7 weeks, the mean birth weight was 7.6 lb, and mean Apgar scores at 1 and 5 minutes after birth were 8.2 and 9.0, respectively. Most outcomes were positive; however, three babies (6.1%) had birth defects, and 17 (34.7%) of the women experienced postpartum depression. The mean number of obstetric complications in the group was 1.3, and 13 (26.5%) of the women delivered by cesarean section. Women who showed symptoms of either anorexia nervosa or bulimia nervosa during pregnancy had a higher frequency of birth by cesarean section and postpartum depression than did nonsymptomatic women. CONCLUSIONS: Pregnant women with active eating disorders appear to be at greater risk for delivery by cesarean section and for postpartum depression. Pregnant women with past or current eating disorders should be viewed as being at high risk and monitored closely both during and after pregnancy to optimize maternal and fetal outcomes.

Pregnancy: outcome and impact on symptomatology in a cohort of eating-disordered women.

OBJECTIVE: This study investigates both the impact of eating disorders (ED) on pregnancy outcome and the impact of pregnancy on cognitive and behavioral symptoms of EDs. METHOD: Data on pregnancy outcome (live birth [LB], therapeutic abortion [TAB], and spontaneous abortion [SAB]) and ED symptomatology were collected as part of a large, prospective longitudinal study of anorexia nervosa (AN) and bulimia nervosa (BN). Data were gathered using a semistructured interview administered every 6 months to 246 subjects. RESULTS: We identified 54 women who reported 82 pregnancies (46 LB, 25 TAB, and 11 SAB). Pregnancy outcome was not significantly related to any of the clinical variables studied. Women with BN showed a significant decrease in the severity of their ED symptoms during pregnancy, and this decrease was sustained through 9 months postpartum. Women with AN also demonstrated a significant reduction in ED symptoms, however, these symptoms returned to prepregnancy levels by 6 months postpartum. CONCLUSIONS: Our prospective findings reveal an elevated TAB rate for ED women along with a general reduction in the severity of ED symptoms during pregnancy.

Mortality in eating disorders: a descriptive study.

OBJECTIVE: We report rates and causes of death for a cohort of 246 eating-disordered women and provide descriptive information on their eating disorder and comorbid diagnoses. METHOD: Data on mortality were collected as part of a longitudinal study of anorexia nervosa and bulimia nervosa, now in its 11th year. Other data sources included death certificates, autopsy reports, relative interviews, and a National Death Index search. RESULTS: Seven deaths have occurred during the study, all among anorexic subjects with a history of binging and purging and with comorbid Axis I disorders. The crude mortality rate was 5.1%. The standardized mortality ratios for death (9.6) and suicide (58.1) were significantly elevated (p <. 001). CONCLUSIONS: Anorexia nervosa is associated with a substantial risk of death and suicide. Features correlated with fatal outcome are longer duration of illness, binging and purging, comorbid substance abuse, and comorbid affective disorders.

Assessment of macronutrient and micronutrient intake in women with anorexia nervosa.

OBJECTIVE: The purpose of this study is to evaluate the accuracy of diet history compared to observed food intake in the nutritional assessment of women with anorexia nervosa (AN) and healthy age-matched controls. METHOD: One-month diet history was compared to 1-day observed food intake in 30 women with AN and 28 control subjects. RESULTS: Reported intake by diet history was similar to observed intake for macronutrient composition and fat intake for patients with AN. Reported energy intake was higher than observed intake (1,602 +/- 200 kcal vs. 1,289 +/- 150 kcal, p <.05), but was in agreement with predicted energy expenditure by the Harris-Benedict equation (1,594 +/- 18 kcal, p =.97) in patients with AN. Micronutrient intake by diet history was highly correlated with observed intake in patients with AN. More than one half of the patients with AN failed to meet the recommended dietary allowance (RDA) for vitamin D, calcium, folate, vitamin B12, zinc, magnesium, and copper when assessed by diet history. In contrast to patients with AN, diet history did not correlate with observed intake of energy, macronutrients, or most micronutrients among the controls. DISCUSSION: Diet history is an accurate tool to assess fat intake and macronutrient composition in patients with AN and demonstrates significant micronutrient deficiencies in this population. The agreement between total energy intake and predicted energy expenditure supports the overall utility of the diet history in the nutritional assessment of patients with AN.

Eating disorders.

Eating disorders are common among adolescent girls and young women and are associated with potentially serious medical complications, yet they often go undetected and untreated. All patients with eating disorders should be evaluated and treated for medical complications of the disease at the same time that psychotherapy and nutritional counseling are undertaken. Pharmacologic agents are often useful as adjuncts to psychotherapy for bulimia nervosa or binge-eating disorder; in the case of anorexia nervosa, psychotropic medication is generally reserved for patients with a concurrent psychiatric illness or those who have recovered some weight.

The prevalence of sleep-related eating disorder in psychiatric and non-psychiatric populations.

BACKGROUND: Sleep-related eating disorder is a little-described syndrome combining features of sleep disorders and eating disorders. The behaviour consists of partial arousals from sleep followed by rapid ingestion of food, commonly with at least partial amnesia for the episode the following day. The aim of this study was to provide an estimate of the prevalence of sleep-related eating disorder. METHODS: The Inventory of Nocturnal Eating, a self-report questionnaire addressing nocturnal eating and sleep disturbance, was administered to out-patients (N = 126) and in-patients (N = 24) with eating disorders, obese subjects (N = 126) in a trial of an anorexic agent, depressed subjects (N = 207) in an antidepressant trial, and an unselected group (N = 217) of college students. Sleep-related eating disorder was operationally defined as nocturnal eating with a self-reported reduced level of awareness, occurring at least once per week. RESULTS: Almost 5.0% (33/700) of the sample described symptoms consistent with sleep-related eating disorder. The in-patient eating disorders group had nearly twice the prevalence (16.7%) of the out-patient eating disorder sample (8.7%), which had nearly twice the prevalence of the next highest group, the student sample (4.6%). Subjects with sleep-related eating disorder endorsed more symptoms consistent with sleep disorders and had higher levels of depression and dissociation than those without nocturnal eating. CONCLUSIONS: Sleep-related eating disorder is more common than is generally recognized, especially in those with a daytime eating disorder. Sleep disorder symptoms are often associated with sleep-related eating disorder, as are depression and dissociation. Evaluation of individuals with eating disorders should include assessment for sleep-related eating.

Recovery and relapse in anorexia and bulimia nervosa: a 7.5-year follow-up study.

OBJECTIVE: To assess the course and outcome of anorexia nervosa (AN) and bulimia nervosa (BN) at a median of 90 months of follow-up in a large cohort of women with eating disorders. METHOD: A prospective, naturalistic, longitudinal design was used to map the course of AN and BN in 246 women. Follow-up data are presented in terms of full and partial recovery, predictors of time to recovery, and rates and predictors of relapse. RESULTS: The full recovery rate of women with BN was significantly higher than that of women with AN, with 74% of those with BN and 33% of those with AN achieving full recovery by a median of 90 months of follow-up. Intake diagnosis of AN was the strongest predictor of worse outcome. No predictors of recovery emerged among bulimic subjects. Eighty-three percent of women with AN and 99% of those with BN achieved partial recovery. Approximately one third of both women with AN and women with BN relapsed after full recovery. No predictors of relapse emerged. CONCLUSIONS: The findings suggest that the course of AN is characterized by high rates of partial recovery and low rates of full recovery, while the course of BN is characterized by higher rates of both partial and full recovery.

The effects of anorexia nervosa on bone metabolism in female adolescents.

Osteopenia is a frequent, often persistent, complication of anorexia nervosa (AN) in adolescent girls and occurs during a critical time in bone development. Little is known about bone metabolism in this patient population. Therefore, we measured bone density (BMD) and body composition by dual energy x-ray absorptiometry, nutritional status, bone turnover, calcium, and hormonal status in 19 adolescent girls with AN (mean +/- SEM, 16.0+/-0.4 yr) and 19 bone age-matched controls. The mean duration of AN was 19+/-5 months. Spinal (L1-L4) osteopenia was common in AN. Lumbar anterioposterior BMD was more than 1 SD below the mean in 42% of patients, and lateral spine BMD was more than 1 SD below in 63% of patients compared with controls. Lean body mass significantly predicted lumbar bone mineral content (r = 0.75; P < 0.0001) in controls only. In AN, duration of illness was the most significant predictor of spinal BMD (lumbar: r = -0.44; P = 0.06; lateral: r = -0.59; P = 0.008). AN adolescents with mature BA (15 yr and greater) were hypogonadal [estradiol, 16.2+/-1.9 vs. 23.3+/-1.6 pg/mL (P = 0.01); free testosterone, 0.70+/-0.17 vs. 1.36+/-0.14 pg/mL (P = 0.01)] although dehydroepiandrosterone sulfate and urinary free cortisol levels did not differ. Leptin levels were reduced in AN (2.9+/-2.1 vs. 16.5+/-1.8 ng/mL; P < 0.0001). Insulin-like growth factor I (IGF-I) was reduced in AN to 50% of control levels (219+/-41 vs. 511+/-35 ng/mL; P < 0.0001) and correlated with all measures of nutritional status, particularly leptin (r = 0.80; P < 0.0001). Surrogate markers of bone formation, serum osteocalcin (OC) and bone-specific alkaline phosphatase (BSAP), were significantly (P = 0.02) reduced in AN vs. controls (OC, 39.1+/-6.4 vs. 59.2+/-5.2 ng/mL; BSAP, 27.9+/-4.0 vs. 40.6+/-3.4 U/L). The majority of the variation in bone formation in AN was due to IGF-I levels (OC: r2 = 0.72; P = 0.002; BSAP: r2 = 0.53; P = 0.01) in stepwise regression analyses. Bone resorption was comparable in patients and controls. These data demonstrate that bone formation is reduced and uncoupled to bone resorption in mature adolescents with AN in association with low bone density. Lean body mass was a significant predictor of BMD in controls, but not AN patients. The major correlate of bone formation in AN was the nutritionally dependent bone trophic factor, IGF-I. Reduced IGF-I during the critical period of bone mineral accumulation may be an important factor in the development of osteopenia in adolescents with AN.

Exposure to the mass media and weight concerns among girls.

OBJECTIVE: To assess the influence of the media on girls' weight concerns, weight control/loss behaviors, and perceptions of body weight and shape. DESIGN: Cross-sectional survey completed in school. The questionnaire assessed body weight, dissatisfaction with body weight and shape, exposure to fashion magazines, the impact of media on feelings about weight and shape, attributes of and preferences for body types, and whether subjects had gone on a diet to lose weight or initiated exercise because of an article in a magazine. SETTING: Mandatory physical education class in public elementary, junior high, and high schools. PARTICIPANTS: Subjects included 548 5th- through 12th-grade girls in a working-class suburb in the northeastern United States. OUTCOME MEASURES: Perceived influence of fashion magazines on body dissatisfaction, idea of the perfect body shape, dieting to lose weight, and initiating an exercise program. RESULTS: Pictures in magazines had a strong impact on girls' perceptions of their weight and shape. Of the girls, 69% reported that magazine pictures influence their idea of the perfect body shape, and 47% reported wanting to lose weight because of magazine pictures. There was a positive linear association between the frequency of reading women's magazines and the prevalence of having dieted to lose weight because of a magazine article, initiating an exercise program because of a magazine article, wanting to lose weight because of pictures in magazines, and feeling that pictures in magazines influence their idea of the perfect body shape. In multivariate logistic regression models controlling for weight status (overweight vs not overweight), school level (elementary vs junior high school, elementary vs high school), and race/ethnic group, girls who were frequent readers of fashion magazines were two to three times more likely than infrequent readers to diet to lose weight because of a magazine article (odds ratio [OR] = 2.11, 95% confidence interval [CI]: 1.19-3.75); to exercise to lose weight because of a magazine article (OR = 3.02, 95% CI: 1.77-5.17); and to feel that magazines influence what they believe is the ideal body shape (OR = 2.81; 95% CI: 1.72-4.58). In addition, moderate-frequency readers were more likely than infrequent readers of fashion magazines to report exercising because of a magazine article (OR = 1.94; 95% CI: 1.14-3.30) and feeling that magazines influence what they believe is the ideal body shape (OR = 2.03; 95% CI: 1.30-3.15). DISCUSSION: The majority of the preadolescent and adolescent girls in this school-based study were unhappy with their body weight and shape. This discontentment was strongly related to the frequency of reading fashion magazines. Although previous studies have concluded that the print media promotes an unrealistically thin body ideal, which in turn is at least partially responsible for promoting eating disorders, the present study is the first that we are aware of to assess directly the impact of the print media on the weight and body shape beliefs of young girls. We observed that the frequency of reading fashion magazines was positively associated with the prevalence of having dieted to lose weight, having gone on a diet because of a magazine article, exercising to lose weight or improve body shape, and deciding to exercise because of a magazine article. Given the substantial health risk associated with overweight and the fact that during the past 2 decades the prevalence of overweight has increased sharply among children and adolescents, it is not prudent to suggest that overweight girls should accept their body shape and not be encouraged to lose weight. However, aspiring to look like underweight models may have deleterious psychological consequences. The results suggest that the print media aimed at young girls could serve a public health role by refraining from relying on models who are severely underweight and printing more articles on the benefits of physical

Distinguishing recovery from remission in a cohort of bulimic women: how should asymptomatic periods be described?

BACKGROUND: Empirical definitions of remission and recovery from eating disorders are needed to understand outcome data and compare results across studies. METHOD: 106 treatment-seeking women with bulimia nervosa, who had abstained from binging and purging for at least 4 weeks, were followed prospectively. Relapse was defined as at least 4 consecutive weeks of either binging and purging weekly or binging two or more times per week, regardless of purging. Recovery was differentiated from remission based on the probability of relapse. The minimum number of weeks after which the risk of relapse leveled off was used as the cut-off to distinguish between the two outcomes. Kaplan-Meier methods were used to estimate the weekly probability of relapse. RESULTS: When defining remission as at least 4 weeks of being asymptomatic, a quarter of the women relapsed within 11 weeks. By 37 weeks, only 49% of the women remained asymptomatic (95% CI, 41-61). The probability of relapse was substantial for approximately a year after a woman ceased to binge and purge. CONCLUSION: Bulimia nervosa is an episodic disorder. As a conservative approach, periods of being asymptomatic that last less than 1 year should be labeled as remissions, not recoveries.

Eating disorders in males: a report on 135 patients.

OBJECTIVE: The goal of this study was to better understand the etiology, clinical characteristics, and prognosis of eating disorders in males. METHOD: All males with eating disorders who had been treated at Massachusetts General Hospital from Jan. 1, 1980, to Dec. 31, 1994, were identified. Hospital charts and psychiatric departmental records were reviewed to verify that the eating disorders met DSM-IV criteria and to abstract demographic and clinical data. RESULTS: One hundred thirty-five males with eating disorders were identified, of whom 62 (46%) were bulimic, 30 (22%) were anorexic, and 43 (32%) met criteria for an eating disorder not otherwise specified. There were marked differences in sexual orientation by diagnostic group; 42% of the male bulimic patients were identified as either homosexual or bisexual, and 58% of the anorexic patients were identified as asexual. Comorbid psychiatric disorders were common, particularly major depressive disorder (54% of all patients), substance abuse (37%), and personality disorder (26%). Many patients had a family history of affective disorder (29%) or alcoholism (37%). CONCLUSIONS: While most characteristics of males and females with eating disorders are similar, homosexuality/bisexuality appears to be a specific risk factor for males, especially for those who develop bulimia nervosa. Future research on the link between sexual orientation and eating disorders would help guide prevention and treatment strategies.

Disordered eating: can women accurately recall their binging and purging behaviors 10 years later?

OBJECTIVE: To test women's ability to recall their past binging and purging behaviors. DESIGN: Ten-year follow-up study of women who had participated in a cross-sectional survey during college. SUBJECTS: In 1982, a sample of freshman and senior women at a large university in the Boston area were questioned about their weight, dieting history, bulimic symptoms, and eating patterns, attitudes, and concerns. In 1992, all subjects who responded to the 1982 survey were followed up to assess changes in bulimic symptoms and ability to recall past behaviors. RESULTS: Among the 476 women who responded to both surveys, the percentage in 1992 who reported having ever binged and/or purged was less than the percentage in 1982, indicating that the recall of past behaviors was less than perfect. Denial in 1992 of ever having engaged in the behaviors ranged from 22% among the women who were self-inducing vomiting in 1982 to 64% among the women who had reported current fasting or strict dieting in 1982. Recall of past behaviors in 1992 was better among the women who had been current bingers or purgers in 1982. CONCLUSION: Our results demonstrate that ability to recall past binging and purging is only modest. Therefore to better understand the mental and physical health consequences of these behaviors this information should be collected prospectively.

Comorbidity and outcome in eating disorders.

This article reviews the data on comorbidity, course, and outcome in anorexia nervosa and bulimia nervosa. Recovery, relapse, the process of recovery, and predictors of outcome are reviewed. Although significant differences exist among outcome studies, the data suggest that patients with anorexia and bulimia tend to improve symptomatically over time. Anorexia nervosa and bulimia nervosa are associated with substantial rates of comorbidity. The relationship between eating disorders and depression, anxiety disorders, substance abuse, and personality disorders is discussed.

Subtyping eating disorders: is it justified?

OBJECTIVE: DSM-IV subtypes anorexia nervosa by the presence or absence of bulimic symptoms. Assessing whether bulimic symptoms are related to the probability of recovery can provide justification for subtyping of anorexia. METHOD: Two hundred twenty-five treatment-seeking women with anorexia and/or bulimia nervosa were interviewed every 3 months for up to 4 years. Survival methods were used for analyses. RESULTS: Less than half of the entire cohort recovered; however, the great majority of the women became less symptomatic over time. Contrary to findings from previous studies, bulimic anorexics had a higher rate of recovery than restricting anorexics. CONCLUSION: Differences in course provide some support for the subtyping of anorexia nervosa. Additional prospective studies are needed before subtyping can be warranted.

Anger attacks in eating disorders.

As central nervous system serotonergic dysregulation has been postulated to exist in both eating and aggression disorders, we hypothesized that anger attacks would be more common among patients with eating disorders than among control subjects. In addition, we wanted to examine possible relationships between the presence of anger attacks and the type or severity of the eating disorder. Subjects were 39 normal female volunteers and 132 female outpatients with anorexia nervosa, bulimia nervosa, or both. Forty-one (31%) of the patients met criteria for anger attacks compared with four (10%) of the control subjects. Bulimic patients reported the highest prevalence of anger attacks to be associated with greater severity of illness. In addition, patients with eating disorders who have anger attacks had significantly more depressive symptoms than patients without these attacks. Central serotonergic function is involved in such diverse processes as feeding behavior, mood regulation, and anger and aggression. The higher prevalence of anger attacks among patients than among control subjects may reflect central hyposerotonergic function, found in previous studies to be present in both eating disorders and pathologic aggression. Supporting this interpretation is the finding that the prevalence of anger attacks increased, although nonsignificantly, with the severity of bulimia, which has previously been shown to be inversely correlated with central serotonergic activity.

The effect of administration method: a comparison of the Rapaport and Exner Rorschach systems.

This study compared two Rorschach administration methods across a number of test variables. With a within-subjects, counter-balanced design, 20 female subjects randomly received either an initial Rapaport (Rapaport, Gill, & Schafer, 1968) or an Exner (Exner, 1974, 1986) Rorschach administration. Results showed that the Exner administration produced significantly more Color (C), Shading (Shd), and Blend (B) responses than did the Rapaport administration. Intersystem differences were most prominent on the first presentation of the two administrations. The first Exner administration produced significantly more C, Shd, and Blend responses than did the first Rapaport administration. Findings are discussed in light of their clinical implications, limitations in the experimental design, and suggestions for improving future research.
