Long-Term Behavioral Health Care Unbundled: The Impact Of Comorbidity And Aggression On Caregiver Strain And Service Costs For Individuals With Intellectual Disabilities, Kristine Tevis
Department of Psychology: Dissertations, Theses, and Student Research
Individuals with intellectual disabilities represent a unique population with an array of needs. High rates of comorbid mental and physical health conditions as well as the presence of disruptive behaviors pose significant challenges to service providers and funding entities. Existing cost models may underestimate these specialized needs and limit access to required services. Through secondary analysis of archival health data from individuals with intellectual disabilities at one agency in Nebraska (N=73), the current study examines how individual characteristics and aggression influence cost and caregiver strain from a systems theory perspective. Bivariate comparisons revealed that more severe aggression and more frequent …

The Contribution Of A Polygenic Risk Score To Individual Differences In Aggressive Behavior: The Moderating And Mediating Roles Of Stressful Events, Christa C. Christ
Department of Psychology: Dissertations, Theses, and Student Research
Although aggression can be beneficial in certain situations (e.g. playing sports, self-defense), excessive and inappropriate aggression can lead to adverse physical and psychological health outcomes in both perpetrators and victims. Genetic susceptibility to negative environments can increase the likelihood of aggressive behavior in the context of situational risk factors. Low efficiency of serotonin neurotransmission and exposure to stress appear to play a prominent role in the etiology of aggressive behavior. A set of three studies assessed the contribution of polygenic risk (TPH2 rs4570625, SLC6A4 5-HTTLPR+rs25531, HTR1B rs13212041, MAOA uVNTR) to aggressive behavior, including alcohol-related aggression, in university students at varying …

Effects Of Alcohol Intoxication And Neurocognitive Processing On Intimate Partner Aggression, Rosalita C. Maldonado
Department of Psychology: Dissertations, Theses, and Student Research
Intimate partner aggression (IPA) is a serious public health concern that occurs with alarming frequency, results in both physical and psychological harm to victims, and costs billions of dollars per year due to healthcare costs and loss of productivity. These adverse consequences highlight the need to understand risk factors of IPA perpetration. Attempts to identify these risk factors have focused mostly on broad factors that may predispose someone to perpetrate aggression, including individual demographic and dispositional characteristics (e.g., low socioeconomic status, psychopathy). Although valuable, this knowledge cannot reveal the specific circumstances that may prompt an individual to perpetrate aggression against …

Emotional, Social, And Cognitive Correlates Of Stalking And Intrusive Harassment., Allissa Marquez
Department of Psychology: Dissertations, Theses, and Student Research
Although stalking has been recognized as social problem for the last twenty years, few studies have examined the treatment needs or effectiveness with these persistent offenders. The dearth of information on appropriate intervention is in part related to the difficulty of operationalizing stalking behavior in empirical studies. Accordingly, the present study sought to examine clinically relevant indicators of functioning using both categorical and continuous definitions of stalking behavior. Two hundred and fifty male prisoners were surveyed about their engagement in intrusive and aggressive behaviors during a significant conflict, as well as their social, emotional, and cognitive functioning. Results indicated quantitative …
