Behavior Skills Training with Zoological Staff to Increase Killer Whale Attending Behavior.

Attending is a requisite behavior for interactions between animals in zoological care and their care specialist (trainers). Head-dropping behavior (HDB) is incompatible with attending and was observed with two killer whales during whale-trainer interactions (WTI). Initial observations also noted inconsistencies in the trainers' application of shaping procedures during WTI. A three-part plan was developed to address trainers procedural fidelity, increase whale attending during WTI, and program for the behavioral generalization and maintenance of the whale-trainer dyads (dyad). First, behavior skills training (BST) was used to instruct trainers on discrete trial training (DTT). Second, the trainers' applied their acquired skill of DTT, targeting attending behavior, with their whale during WTI. Third, behavioral generalization was programed by switching the dyad pairs in an additional DTT generalization phase. The findings demonstrated a strong positive correlation between trainer DTT fidelity and whale attending. Finally, the results suggest that future assessments of behavioral management programs with zoological trainers and animals are warranted.

100 midlife women with eating disorders: a phenomenological analysis of etiology.

This study analyzed eating disorder (ED) etiological factors for 100 midlife women ED inpatients, grouped by ED onset age: < 40 and > or = 40 years. Interpretative Phenomenological Analysis classified ED etiological influences into background contributors, immediate triggers, or sustainers. Family-of-origin issues, predominantly parental maltreatment, emerged as important background contributors, but not immediate ED triggers, regardless of onset age. Body image issues were also major background contributors regardless of onset age and further served as immediate ED triggers for many of the younger-onset patients, but not the older-onset patients. Family-of-choice and health issues were unimportant for younger-onset patients but were important ED contributors and triggers for older-onset patients. Emergent etiological differences suggest differential assessment and treatment needs for midlife ED patients based on ED onset age.

Profile of 50 women with midlife-onset eating disorders.

The aim of this study was to present a detailed profile of 50 women eating disorder (ED) inpatients who reported first ED onset at age 40 or above. We assessed patients' sociodemographics, severity-of-illness, comorbid diagnoses, personality profiles, and short-term treatment outcomes. Compared to patients of more traditional young adult ages, results revealed unique features of midlife-onset ED inpatients, including less severe and less common self-reported ED symptomology measured by the EDI-2; a predominance of pure restricting behaviors and rarity of bulimia; similar rates of co-occurring depression and anxiety but of less severity; fewer substance use disorders with a predominance of sedating/calming substance usage; many fewer Cluster C diagnoses on Axis II; substantially greater histories of sexual abuse; and different MMPI-2 profiles emphasizing much greater denial. The corresponding needs among midlife-onset ED inpatients for specialized assessment and treatment interventions are considered.

Treatment responses of inpatient eating disorder women with and without co-occurring obsessive-compulsive disorder.

We analyzed the influence of co-occurring obsessive-compulsive disorder (OCD) on response to eating disorder (ED) treatment among 2,971 female inpatients. We assessed treatment response using Eating Disorder Inventory-2 and DSM-IV ED criteria. Multivariate analyses included sociodemographics, illness severity, and co-occurring Axis I/II diagnoses. ED inpatients with OCD had greater ED severity than those without OCD. However, no differences occurred in short- and intermediate-term ED outcomes. Patients with and without OCD evidenced the same degree of change in EDI-2 scores admission-to-discharge and discharge-to-one-year; and 93% of patients both with and without OCD no longer evidenced a DSM-IV ED diagnosis one-year post-discharge. Results suggest that with co-occurring OCD treated using evidence-based interventions ED inpatients with and without OCD may have similar prognoses.

The deconstruction of the Hy Scale of MMPI-2: failure of RC3 in measuring somatic symptom expression.

The MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) Clinical Scales have a long history in psychological assessment. Recently, Tellegen et al. (2003) conducted a series of analyses to restructure the scales to reduce what they considered to be problems that limit scale functioning. In a critique of the Restructured Clinical (RC) Scales published in this issue, Nichols (2006/this issue) questions a number of aspects of the approach Tellegen et al. took including their theoretical assumptions, methods of analysis, and failures to report important information needed for scale evaluation such as relationships with existing scales. We concur with many points raised by Nichols. In our analysis of the performance of the RC3 scale, we found that it has "drifted" so far from the original Hy scale as to be a completely different measure- a scale of cynical attitudes that is already well represented in existing MMPI-2 measures. In this article, we take these concerns a step further and examine the history and construct validity of the Hy scale in evaluating the somatic expression of problems that the original authors (McKinley & Hathaway, 1944) intended. We also include new information from a medical setting, an application not represented in Tellegen et al.'s RC Scale monograph. In agreement with Rogers et al. (2006/this issue), it is our conclusion that some RC Scales do not represent the measurement domain of the original scales and should not be relied on for or used to refine traditional interpretation, particularly in medical or forensic situations (such as personal injury cases) because of their confusing and conflicting results.

Psychiatric comorbidities of female inpatients with eating disorders.

OBJECTIVE: We analyze 27 point-prevalent DSM-IV Axis I comorbidities for eating disorder inpatients. METHODS: The sample included 2436 female inpatients treated between January 1, 1995, and December 31, 2000, for primary DSM-IV diagnoses of anorexia, bulimia, and eating disorder not otherwise specified. Analyses were multivariate analysis of variance and multinomial logistic regression; sociodemographics and severity-of-illness measures were controlled. RESULTS: Ninety-seven percent of patients evidenced > or = 1 comorbid diagnoses; 94% evidenced comorbid mood disorders, largely unipolar depression, with no differences across eating disorders; 56% evidenced anxiety disorders, with no differences across eating disorders; and 22% evidenced substance use disorders, with significant differences across eating disorders (p < .0001). Five specific diagnoses differed across eating disorders. Alcohol abuse/dependence was twice as likely with bulimia (p < .0001); polysubstance abuse/dependence three times as likely with bulimia (p < .0001); obsessive-compulsive disorder twice as likely with restricting and binge/purge anorexia (p < .01); posttraumatic stress disorder twice as likely with binge-purge anorexia (p < .05); schizophrenia/other psychoses three times more likely with restricting anorexia (p < .05) and two times with binge-purge anorexia (p < .05). CONCLUSIONS: New findings emerged: extremely high comorbidity regardless of eating disorder, ubiquitous depression across all eating disorders, no difference in overall rate of anxiety disorders across eating disorders, greater posttraumatic stress disorder in binge-purge anorexia, more psychotic diagnoses in anorexia. Certain previous findings were confirmed: more obsessive-compulsive disorder in anorexia; more substance use in bulimia; and a replicated comorbidity rank-ordering for eating disorder patients: mood, anxiety, and substance use disorders, respectively.

Eating disorders across the life span.

Clearly, eating disorders appear in both men and women across the entire life span. Nurses must be aware of eating disorder issues in populations such as children and adolescents, adult men, middle-aged women, and older adults so that proper screening and treatment can occur to reduce the consequences of these potentially life-threatening illnesses.

Efficacy of voluntary nasogastric tube feeding in female inpatients with anorexia nervosa.

BACKGROUND: This investigation assesses the efficacy of a voluntary nasogastric tube feeding protocol on the weight gain of patients with anorexia nervosa, tube feeding's effect on recovery from the psychologic aspects of anorexia, patient satisfaction with treatment, and medical complications. METHODS: The study included a nonrandomized retrospective review of 381 female inpatients with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition diagnosis of anorexia nervosa, both subtypes. A total of 155 patients received tube feeding and oral refeeding; 226 received oral refeeding alone. Recovery from the psychologic aspects of anorexia was measured by the change in Eating Disorder Inventory-2 scores between admission and discharge. Patient satisfaction with treatment was measured with a patient satisfaction questionnaire completed at discharge. Repeated measures and multivariate analyses were performed. RESULTS: When severity-of-illness and caloric intake differences between patients with and without tube feeding were controlled, patients who received tube feeding gained significantly more weight per treatment week than those who received oral kilocalories alone. Patients who received tube feeding for at least one-half their length of stay gained 1 kg/week versus 0.77 kg/week for patients receiving oral refeeding alone. Tube-fed patients evidenced no differences in recovery from anorexia's psychologic aspects, satisfaction with treatment, or medical complication frequency. CONCLUSIONS: In residential psychiatric treatment settings in which intensive therapeutic interventions and appropriate medical monitoring can manage potential psychologic and medical risks, tube feeding's weight gain benefits may be a viable and safe option in treating anorexia.
