Clinician Perspectives On Fistula Mental Health, Victoria K. Leonard

Doctoral Dissertations

Background – Obstetric fistula is a childbirth injury caused by prolonged labor that leads to stillbirth and incontinence, spurring social exclusion and isolation. These layers of trauma put women with fistula at great risk for psychological suffering, which has profound negative socioeconomic impacts on them, their families, and communities. This study captured treatment as usual at Comprehensive Community Based Rehabilitation in Tanzania (CCBRT), the country’s largest provider of fistula care.

Method – Improving holistic fistula treatment requires engaging the clinicians who care for women with fistula. This study aimed to investigate the training, beliefs, and treatment approaches of nurses and …

Motivated Attention To Social And Nonsocial Reward Images: Examining Relations With Externalizing Risk In Children, Adaeze C. Egwuatu

Doctoral Dissertations

Children that exhibit issues with externalizing behaviors often experience maladaptive outcomes in later life. Externalizing problems during middle childhood (e.g., 6-10 years old) are linked to issues with emotion regulation, which are, in turn, caused by disrupted attention and emotion reactivity to reward. Externalizing problems during this period have also been linked diminished processing of social reward stimuli, suggesting externalizing risk in children may be reflected in contrasting patterns in processing of non-social and social rewards. However, research comparing how differences in affective processing of specific reward content (i.e. social versus non-social) patterns relate to externalizing behavior within normative development …

Hearing And Seeing A Speaker: How Perceptual And Cognitive Factors Modulate The Dynamics Of Audiovisual Speech Perception, Elina Kaplan

Doctoral Dissertations

In face-to-face conversations, listeners process and combine speech information obtained from hearing and seeing the speaker talk. Audiovisual speech typically leads to more robust recognition of speech, as it provides more information for recognition but also as it helps listeners adjust to speaker idiosyncrasies. The goal of the current thesis was to examine how certain perceptual and cognitive factors modulate how listeners use visual speech to facilitate momentary speech perception and to adjust to a speaker’s idiosyncrasies. Results showed that (older) listeners’ sensitivity to cross-modal synchrony is related to the size of the audiovisual interactions during early perceptual processing. Furthermore, …

A Program Evaluation Of A Drug And Alcohol Family Treatment Program, Katrina Ramirez

Doctoral Dissertations

The current study is a program evaluation at John Muir Behavioral Health, Center for Recovery. The research determined the effectiveness of the program at Center for Recovery that is offered to patients that struggle with substance use disorder and their families. The purpose of this study is to assess patients’ behavioral, cognitive and social/environmental factors as it relates to their commitment to sobriety and examine how the involvement of family members influences the patient’s recovery process. I utilized a mixed methodology of quantitative and qualitative interviews of patients and family members. The findings suggest depressive symptoms were negatively correlated with …

Mediators And Moderators Of Childhood Family Adversity And Adult Cortisol Response: The Role Of Marital Conflict Behavior, Jeffrey P. Winer

Doctoral Dissertations

Childhood family adversity influences behavioral and physiological response processes to acute interpersonal stress. Additionally, conflict behaviors in marriage are primary determinants of stress response and related psychological problems in adulthood. As little research has examined these two important literatures simultaneously, further work is warranted to clarify the role of marital conflict behavior in the relation between childhood family adversity and adult cortisol response to conflict. The current study examined relations between childhood family adversity, observed marital conflict behaviors, and salivary cortisol in response to acute marital conflict among 228 different-sex newlywed couples. We examined intrapersonal “actor” effects as candidate mediators …

The Effects Of Predictability On Stereotypic Behavior In Nonclinical Adult Humans (Homo Sapiens) And Rhesus Macaques (Macaca Mulatta), Amy Ryan

Doctoral Dissertations

Stereotypies, or repetitive and purposeless behaviors, are observed in both humans and other animals. They have been primarily studied in captive animal and clinical human populations with comparably little research devoted to understanding less severe levels of stereotypies observed in nonclinical populations of adult humans and in most captive animals. As these behaviors are sometimes associated with routine events, I explored the relationship between the predictability of anticipated events and mild stereotypies. I studied this relationship in captive rhesus macaques and a novel comparison group of adult humans from a nonclinical population. I designed two experimental paradigms, a wait paradigm …

The Neural Correlates Of Emotion Reactivity And Regulation In Young Children With Adhd, Claudia I. Lugo-Candelas

Doctoral Dissertations

Attention-deficit hyperactivity disorder (ADHD) is the most frequently occurring pediatric neurobehavioral disorder. Although emotion reactivity and regulation are frequently impaired in ADHD, few studies have examined these factors in preschool aged children with ADHD, and none have explored the neural correlates of emotion reactivity and regulation in this group though event-related potentials (ERPs). Children aged 4 to 7 with (n = 24) and without (n = 30) ADHD symptoms completed an attention task composed of four blocks: baseline, frustration, suppression, and recovery. In the frustration and suppression blocks, negative affect was induced by false negative feedback. During the …

Investigating The Role Of Testosterone Signaling At Androgen Receptors In Resiliency To Social Stress, Catherine Tucker Clinard

Doctoral Dissertations

Social experience can alter how individuals cope with stressful events and contribute to individual differences in stress vulnerability. We have previously tested dominant and subordinate male Syrian hamsters (Mesocricetus auratus) in a conditioned defeat model and found that dominant individuals show reduced defeat-induced changes in behavior compared to subordinates. Dominant hamsters also show increased neural activation following social defeat stress in brain regions that regulate social behavior and coping with stress, including the medial amygdala (MeA). Because winning aggressive encounters generates a surge in plasma testosterone and androgen receptors are abundant in the MeA, we tested whether testosterone …

Therapy Dogs In The College Classroom: The Effect Of Dogs On Stress, Anxiety, And Spanish L2 Phonological Learning And Performance, Elaine Maralee Henry

Doctoral Dissertations

Anxiety and stress invoked by the second language classroom setting has the ability to cause numerous detrimental physiological changes which impair the learning process. A more natural, “immersion” type atmosphere is often desired when teaching a second language; however, this is not typically possible with college classes. Therefore, the addition of therapy dogs to college second language classes may be a beneficial solution since therapy dogs are frequently cited as having the ability to lower stress and anxiety in many different settings. Stroking and interacting with a dog may reduce many markers of stress, including blood pressure, heart rate, and …
