Mental health risks within the adult male homosexual population have been researched; however no comprehensive synthesis of research findings was identified. The purpose of this research was to synthesize current research findings of mental health risks among the male homosexual population. This was limited to international studies conducted between 2003-2008 focusing on suicide, Eating Disorders, and Depression. These findings may serve as an educational resource for nurses and healthcare providers. Findings indicated that homosexual men are at an increased risk for suicide, Eating Disorders, and Depression. Several possible causes were identified, such as internalized homophobia, minority stress, social isolation, gender role orientation, community pressure, and comorbidity with mental health disorders. Limitations included small sample sizes, with limited age and ethnic diversity. Non probability sampling and lack of consistency in measurement of research variables limited the generalizability of the findings. Nursing education and practice should emphasize culturally-competent care and specific healthcare needs of this population. A focus on assessment and awareness of healthcare risks may be beneficial. Recommendations for future research include large, probability samples, and possibly population-based surveys. Research should focus on stressors and protective factors to formulate culturally sensitive interventions. Clinical trials of interventions are needed to form evidence-based practice guidelines.

A booklet was completed by 7 anorexia nervosa patients, 12 bulimia nervosa patients, and 19 non-clinical individuals. The research instrument was designed to measure transgenerational family processes, interpersonal relations orientations, coping strategies, and stressful behavioral response patterns of anorexics and bulimics. Separate multivariate analysis of variance procedures were performed on the aforementioned variables to determine significant differences among the groups. The findings indicated that significant differences existed among the groups in regards to transgenerational family processes (F = .000), interpersonal relations orientations (F = .014), and coping strategies (F = .003). / Ph.

Forty-three college athletes participated (male basketball players, n=13; female basketball players, n=11; male swimmers, n=9; female swimmers, n=10). Two administrations of four self-report questionnaires were completed. Psychological traits of locus of control and self-monitoring were compared to perceptions of body image and predisposition to eating disorders. Measurements used were Rotter Internal-External Locus of Control Scale, Self-Monitoring Scale, Multidimensional Body-Self Relations Questionnaire, and the Eating Disorder Inventory-2. Males tended to have lower drive for thinness linked with lower fat anxiety as compared to females. Females associated body dissatisfaction with perception of weight. In females, self-monitoring was correlated with feelings of physical attractiveness. Findings support previous literature proposing that women attach negative feelings to the body in relation to an cultural thin ideal. Reliability estimates lacked significance in general. This suggests that the measurements used are not predictive for these subgroups. / Master of Science

Many psychiatric disorders are characterized by difficulties in working towards long-term goals. Effort-based decision-making (EBDM) provides a useful framework for understanding this phenomenon, particularly for parsing motivation into various components, and exploring the underpinnings of cost-benefit computations. Importantly, large changes in arousal, like those introduced by strong emotions and stress, can significantly influence high-order cognitive processes. However, the mechanistic properties underlying associations between emotions and various components of EBDM remain unclear, particularly at psychological, neurological and endocrinological levels. The following experiments were designed to examine the effect of positive and negative emotions on various components of EBDM across psychiatric conditions characterized by motivational and impulse-related deficits. In the first experiment, comparing emotional versus behavioural inhibitory systems in binge eating disorder, inverse relationships between disgust sensitivity, inhibitory control and binge-eating behaviours were found, suggesting unique maintenance functions of cognitive-affective links with emotion regulation on eating attitudes. In the second experiment examining neural correlates of effort- and reward-processing in a cannabis using population, findings indicate fronto-striatal but also posterior cortical processing alterations during prospective signaling of effort and reward signals and during effort-reward information integration. In the final experiment assessing the effects of childhood trauma on acute stress responses and gambling urges in a population of problem gamblers, increased reports of childhood trauma were noted relative to a healthy control group. Childhood trauma subsequently predicted subjective and physiological stress responses, and emotional and physical neglect in childhood was further linked to increased gambling urges. Taken as a whole, these studies suggest that emotions plays a crucial role in moderating various components of EBDM, underscoring the significant impact of emotional states on higher-order cognitive functioning. / Dissertation / Doctor of Philosophy (PhD)

This study is concerned with the nature of suffering as experienced by women struggling with problems related to the body. Since the body is viewed to be integral in the formation of a woman's identity and self-concept, any illness, ailment or deficiency associated with it may lead the woman to experience pain and suffering. To explore meanings of personal suffering related to the body three contexts have been chosen. These are familial breast cancer, eating disorders and infertility. Common themes of suffering that were co-constructed in the interviews between six women participants and myself form the basis of this study. These themes emerged through the process of social constructionism and dialogue. Through the process of language, personal realities and meanings were discussed and shared to elicit a greater understanding of the nature of suffering. A qualitative approach, using the case study method, was also adopted to provide rich descriptions of the different experiences with suffering. The case study presentations illustrate the linguistic domain between the participants and myself. It is hoped that the information presented in this study will contribute to a therapeutic understanding of personal suffering as experienced by women. / Psychology / D. Litt et Phil.

Collegiate and elite female athletes have been identified as a subpopulation at heightened risk for disordered eating and pathogenic weight management practices. It was hypothesized that this increases risk may be related to sport specific pressures (such as team conducted weigh-ins), or the use and frequency of self-weighing. It appears that mandatory, team conducted weigh-ins are not salient to female athletes in regards to experiencing internalization, body image concerns, dietary restraint, negative affect, and bulimic symptomatology. Results, however, indicate that frequency of engagement in self-weighing may be influential in the engagement of disordered eating symptoms. Specifically, athletes who weighed themselves three or more times per week reported significantly more internalization of general societal ideals and athletic body ideals. For body image concerns, athletes who weighed three or more times per week reported being more concerned with their body size/shape than all others. With respect to dietary behaviors, athletes who weighed themselves three or more times per week reported engaging in significantly more caloric restriction than did those who weighed less frequently. For negative affect, the athletes who weighed themselves three or more times per week reported significantly higher levels of both anger and guilt. Finally for bulimic symptomatology, athletes who weighed themselves three or more times a week had significantly higher levels than those who weighed once or twice or not at all.

Indiana University-Purdue University Indianapolis (IUPUI) / Obesity is a substantial threat to the health of over a third of adults in the United States. Some evidence suggests that food attentional bias, or the tendency to automatically direct attention toward food-related stimuli in the environment, may contribute to the development of obesity in susceptible individuals. This study hypothesized that (1) food attentional bias would be positively associated with adiposity, (2) food attentional bias would be positively associated with energy intake and external eating, and (3) energy intake and external eating would partially mediate the association between food attentional bias and adiposity. Data were collected from a sample of 120 undergraduate students. Three measures of food attentional bias were obtained: reaction time bias obtained from a visual dot-probe task and direction bias and duration bias obtained from eye tracking. Adiposity indices of body mass index (kg/m2) and body fat percent were measured using standard medical devices. Data were obtained for two mediators: 1) energy intake was assessed by web-based automated 24-hour dietary recall and 2) external eating was assessed using the External Eating Subscale of the Dutch Eating Behavior Questionnaire. Separate linear regression models examining the association between each measure of food attentional bias with each measure of adiposity (adjusted for age, sex, race/ethnicity, and subjective hunger) indicated no associations. Similarly, linear regression analyses revealed no associations between measures of food attentional bias and energy intake or external eating. Models testing for statistical mediation demonstrated that energy intake and external eating were not significant mediators. However, mediation analyses demonstrated a significant overall effect and direct effect between direction bias and BMI in a reduced sample used to test for energy intake as a mediator, suggesting the presence of an association which may not have been detected in the larger sample due to methodological issues, measurement error, or type I error. Despite the overall null results, these findings, in conjunction with previous studies on food attentional biases and adiposity, highlight the need for future investigations examining prospective associations between food attentional bias and adiposity.

The prevalence of eating disorders (ED) in the United States has increased while the media consistently presents thinner representations of the body. Scholars have found media to negatively influence factors associated with the development of EDs. The purpose of this quantitative nonexperimental cross-sectional survey design study was to explore relationships between exposure levels to MLE and self-esteem, body esteem, and the internalization societal appearance ideals. Participants included undergraduate students or recent graduates majoring in either communications or an alternative major with comparatively less MLE curriculum. The Body Esteem Scale, Sociocultural Attitudes towards Appearance Questionnaire-3, and Rosenberg Self-Esteem Scale Surveys were administered online to examine the variance of 3 dependent variables (self-esteem, body esteem, internalization of societal appearance norms) with 2 independent variables (exposure levels to media literacy curriculum and gender), and a multivariate analysis of variance was used to analyze the data. Results displayed statistically significant differences between all 3 dependent variables with MLE levels. Research in MLE benefits both adults and children by way of providing the necessary tools, knowledge, and skills to be able to fully benefit from various media sources. MLE provides an opportunity to better understand media messages, as well as its influences therein, this way rather than being vulnerable and easily manipulated, one becomes a more knowledgeable and aware media consumer. The results to this study can promote, advocate, and bring awareness to media consumers and today's educators of the importance and need of MLE curriculum beginning at a young age.

Während Leitlinien „Gold-Standards“ für die Psychotherapie bei bulimischen Essstörungen (Bulimia Nervosa und Binge-Eating-Störung) empfehlen, ist über psychotherapeutische Prozessfaktoren bei Essstörungen wenig bekannt. Ziel war es, mit Hilfe des etablierten Generic Model of Psychotherapy zur Systematisierung psychotherapeutischer Prozessfaktoren die aktuelle Literatur zum Einfluss dieser Faktoren auf den Therapieerfolg, operationalisiert als Symptomreduktion oder -remission, auf Basis einer systematischen Datenbanksuche zu sichten. Während der Einfluss des therapeutischen Settings nach bisheriger Forschungslage kaum Schlüsse hinsichtlich des Therapieerfolgs zulässt, konnte dieser durch spezifische Interventionen, frühe Symptomreduktionen und eine gute therapeutische Beziehung vorhergesagt werden. Weitere Forschung zu Prozessfaktoren bei bulimischen Essstörungen erscheint notwendig, um die praktische psychotherapeutische Arbeit zu unterstützen und Behandlungen effektiver gestalten zu können. / While guidelines recommend gold standards for psychotherapy in bulimic eating disorders (bulimia nervosa and binge eating disorder), less is known about psychotherapeutic process aspects. We aimed to summarize the current literature on the impact of process aspects on significant symptom reductions and/or abstinence as treatment outcome using the Generic Model of Psychotherapy. A systematic literature search was conducted. While effects of treatment settings can not yet be estimated, specific interventions, rapid response, and the therapeutic bond repeatedly predicted outcome. Process-outcome research in bulimic eating disorders will be necessary to support clinical practice and to enhance treatment efficacy.
