Hoarding is characterized by (a) the persistent difficulty discarding personal items; (b) clutter that interferes with living areas; and (c) significant distress or functional impairment. Hoarding symptoms often emerge in childhood and adolescence, yet very few studies on hoarding in this age group exist. Current models of hoarding emphasize impairments in decision-making, yet the literature on decision-making processes in hoarding presents inconsistent findings. Preliminary cognitive studies in adults suggest that hoarding may be associated with deficits in value attribution (the tendency to assign value to personal items). Thus, we propose that the Endowment Effect (EE), in which ownership of an item increases its perceived value, may be informative for the study of hoarding symptoms. This study investigated the EE in youth (children and adolescents) with Obsessive-Compulsive Disorder (OCD) and hoarding symptoms. Given that hoarding involves significant difficulty discarding personal items, we hypothesized that hoarding in youth is associated with a higher EE. Thirty youth participants with a confirmed DSM-5 diagnosis of OCD completed the Endowment Task, a game script of the EE; the Wisconsin Card Sorting Test (WCST), a test of cognitive flexibility; and the Balloon-Analogue Risk Task (BART), a test of risky decision-making. The Children’s Saving Inventory-Parent Version (CSI) was used to measure severity of hoarding symptoms. We divided our sample into thirds based on CSI scores to create a ‘High Hoarding’ group (HH; n=12; mean CSI (S.D.)=30.83 (5.47446)) and a ‘Low Hoarding’ group (LH; n=10; mean CSI (S.D.)=5.00 (3.16228)). The HH group demonstrated a higher average EE than the LH group (average EE, 3.22 and 1.59, respectively). In contrast, no significant between-group differences were found on the WCST and the BART (t=0.901, p=0.378 and t=0.338, p=0.739, respectively). The results of this thesis suggest that psychological ownership plays an important role in the manifestation of hoarding symptoms. Thus, we propose that hoarding might be associated with a specific decision-making deficit related to personal possessions. / Thesis / Master of Science (MSc)

David Cash was a college student who found himself in the women's restroom of the Primadonna in Nevada. He witnessed his friend, Jeremy Strohmeyer raping and killing a 7-year-old girl. Cash did not take any action in trying to prevent this heinous crime. There are many elements to consider when bystanders neglect to take action. Research examining bystander apathy in critical situations is lacking, yet the number of violent crimes witnessed by others where intervention is not offered continues to escalate. Bullying often occurs in the presence of others. Bystander apathy is believed to play a passive role in most cases of bullying. This study investigated the psychological symptom patterns of intervening and non-intervening bystanders in bullying events. It was hypothesized that there would be a significant difference in the SLC-90-R profiles between intervening and non-intervening bystanders. It was further hypothesized that gender would significantly interact with the bystander response to witnessing bullying. Data were collected from undergraduate participants at the University of Central Florida through The Psychology Department's Psychological Research Participant System (aka, SONA). Psychological Symptoms were evaluated using the Symptom-Checklist-90-Revised (SCL-90-R). Data was obtained from 135 undergraduate participants. The sample consisted of 42 males and 93 females between 18 to 58 years of age. The participants were categorized by intervening and non-intervening bystanders. A two-way between subjects MANOVA was used to assess the influence of gender and intervening and non-intervening bystanders on the nine SLC-90-R symptom domains. No significant main effects or interaction was observed. However, a review of the univariate analyses revealed a significant gender x intervening interaction on the paranoid ideation subscale, F(1, 131) = 4.823, p = .03. Implications and directions for future research are discussed.

Individuals in the final stages of life are often cared for by informal caregivers whose interpretation of the patient’s signs, symptoms and treatment needs and options may be incongruent with that of healthcare providers (Docherty et al., 2008). Nurses need to fully understand the scope of this disparity. The purpose of this study was to determine how Black caregivers interpreted signs, symptoms, and treatments for symptom relief during the last months of their loved one’s life. The effect on caregiver decision making was explored. This project is a secondary analysis of preexisting qualitative data. Transcripts from 5 focus groups encompassed 53 participants. All participants were Black and informal caregivers or decision makers for a loved one at their loved one’s end of life. Eighty-seven percent of caregivers were female, and a majority had a high school education. The mean age was 66. Transcripts were coded for themes independently by two researchers. To allow for the most open interpretation, no a priori set of codes was utilized. 3 main categories of signs, 4 main categories of symptoms, 4 themes of the interpretation of signs and symptoms, 4 main categories of treatments and interventions, 5 themes of the interpretation of treatments, and 3 themes describing the effect of signs, symptoms, and treatments on decision making were identified. Case examples of the caregiver interpretation process are included. Health care providers need to provide time, clear and simplified language, and additional explanation in communication. Further research combining health literacy measures and qualitative data on interpretations should be conducted.
