The Effects Of Covid-19 Stressors And Supervisor Support On Emotional Exhaustion And Work Engagement, Meiqiao Gu
The Effects Of Covid-19 Stressors And Supervisor Support On Emotional Exhaustion And Work Engagement, Meiqiao Gu
Psychology Theses & Dissertations
Since the onset of the COVID-19 pandemic, working conditions have worsened, subjecting employees to numerous stressors. Analyzing the impact of COVID-19 stressors on employees‘ well-being and work motivation is crucial. The job demands-resources model (JD-R; Demerouti et al., 2001a) provides a framework for evaluating how COVID-19 stressors affect employees‘ well-being and motivation in the workplace. Given the complexity of job characteristics during the COVID-19 pandemic, coupled with challenges in obtaining adequate support from supervisors who are also facing considerable work pressure, this study examines the continued relevance of the JD-R model in this evolving work environment. Specifically, four hypotheses were …
Incremental Validity Of The Mmpi-A-Rf And Maci In A Clinical Outpatient Setting, Madison Smart-Mccarthy
Incremental Validity Of The Mmpi-A-Rf And Maci In A Clinical Outpatient Setting, Madison Smart-Mccarthy
Psychology Theses & Dissertations
With the persistent rise of depression and suicide in adolescents, it is imperative that clinicians select empirically supported measures that accurately assess these conditions (Van Orman, 2022; Sellbom & Suhr, 2020). One empirical method used to evaluate measures is incremental validity. Incremental validity examines the level of improvement in predicting a phenomenon when adding a test or procedure to a combination of other instruments (APA, 2020). Experts regard the Minnesota Multiphasic Personality Inventory—Adolescent Version—Restructured Form (MMPI-A-RF; Archer et al., 2016) and the Millon Adolescent Clinical Inventory (MACI; Millon et al., 1993) as psychometrically sound measures often used in clinical practice. …
Nightmares And Self-Injury Among High-Risk Adolescents: Examining The Role Of Emotion Regulation, Kinjal K. Patel
Nightmares And Self-Injury Among High-Risk Adolescents: Examining The Role Of Emotion Regulation, Kinjal K. Patel
Psychology Theses & Dissertations
Self-injurious thoughts and behaviors (SITBs) are a public health concern among youth. SITB rates rise drastically during adolescence -- a critical and sensitive developmental period characterized by dramatic changes in biological and social systems. Prior research has identified distal risk factors which tell us who is at risk for SITBs. Emerging research suggests proximal risk factors may be useful to identify when an individual may be at risk for SITBs. One promising proximal risk factor for SITBs is sleep problems. Although the relation between sleep problems and SITBs has been widely documented, little is known about the short-term, proximal links …
The Impact Of Mandatory Substance Abuse Counselor Reporting Requirements On Child Maltreatment Reporting Outcomes, Bilgé Özgé Yilmaz
The Impact Of Mandatory Substance Abuse Counselor Reporting Requirements On Child Maltreatment Reporting Outcomes, Bilgé Özgé Yilmaz
Psychology Theses & Dissertations
The present study sought to examine how state-level mandatory reporting policies are associated with child maltreatment reporting through analysis of the National Data Archive on Child Abuse and Neglect (NDACAN, 2021). This study aimed: 1) to examine how the implementation of substance abuse counselor reporting requirements is associated with the reporting process, including the disposition of reports and the presence of substance abuse; and 2) to examine differences in the above outcomes based on associations between non-specific reporting requirements and specific requirements that mention substance use counselors. A quasi-experimental approach with repeated cross-sectional data was utilized, as it is a …

Assessing Sexual Minority Women’S Barriers And Facilitators To Seeking And Accessing Mental And Physical Healthcare: A Mixed Methods Study, Charlotte A. Dawson
Psychology Theses & Dissertations
Sexual minority women (SMW) experience greater mental and physical health concerns when compared to heterosexual women. Three key areas of health SMW report these disparities are: mental health, binge eating/body size, and sexual and reproductive health. SMW also report difficulties accessing healthcare in these three areas. An exploratory sequential mixed methods design was utilized to assess barriers and facilitators to healthcare access for young SMW. Study 1 included 20 semi-structured interviews with SMW, resulting in themes of barriers and facilitators identified by participants. These themes were converted into scale items. In Study 2, an expert panel of mental and physical …
The Mediation Effects Of Adaptive Blindness Strategies On The Relation Between Institutional Betrayal From Military Sexual Assault And Mental Health Symptoms, Rachel L. Davies
The Mediation Effects Of Adaptive Blindness Strategies On The Relation Between Institutional Betrayal From Military Sexual Assault And Mental Health Symptoms, Rachel L. Davies
Psychology Theses & Dissertations
Military sexual assault is a serious and prevalent issue. The frequency with which military sexual assault occurs and the nature of the response to these events within the military system may contribute to institutional betrayal. Institutional betrayal is the failure of an institution, such as the military, to prevent sexual assault from occurring and/or the failure to support a survivor after sexual assault. Adaptive blindness strategies are forms of coping strategies that help individuals navigate a relationship they depend on when there is a betrayal. Two adaptive blindness strategies are self-blame and minimization. Although the adaptive blindness strategies may allow …
The Influence Of Minority Stress, Coping, And A Pandemic On The Relationship Between Sexual Orientation And Mental Health: A Mixed Methods Study, James Michael Macchia
The Influence Of Minority Stress, Coping, And A Pandemic On The Relationship Between Sexual Orientation And Mental Health: A Mixed Methods Study, James Michael Macchia
Psychology Theses & Dissertations
For decades, scientific literature has shown that sexual minority individuals across populations are disproportionately affected by negative mental health outcomes when compared to their heterosexual counterparts. These disparities are largely attributable to minority stress. Coping is a significant factor that can impact the content and severity of mental health outcomes and coping behaviors have been shown to vary based on sexual orientation. Mental health outcomes may also differ between sexual minority subgroups due to additional factors such as double discrimination and bisexual invisibility/erasure. Moreover, factors such as internalized homophobia and community connectedness have demonstrated strong associations with sexual minority mental …
Examining The Experience And Impact Of Teen-To-Teen Crisis Line Work For Youth Volunteers: A Pilot Study, Taylor Kalgren
Examining The Experience And Impact Of Teen-To-Teen Crisis Line Work For Youth Volunteers: A Pilot Study, Taylor Kalgren
Psychology Theses & Dissertations
For young people, suicide is a leading cause of death. In addition, suicidal thoughts and behaviors begin during adolescence, and rates are high during this developmental period. Crisis lines are one of the oldest suicide prevention strategies used today. Crisis line work is challenging, and therefore, examining the health and safety of these operators is critical. Teen-to-teen (t2t) crisis lines are a unique resource where adolescent volunteers help their similarity aged peers. The goal of this pilot study was to begin to evaluate the impact of t2t crisis lines for youth volunteers. Twenty youth crisis line volunteers (ages 15-20) were …
The Effect Of Minority Stress On Sexual Minority College Students' Mental Health: The Role Of General Social Support And Sexuality-Specific Social Support, Lee A. Golembiewski
The Effect Of Minority Stress On Sexual Minority College Students' Mental Health: The Role Of General Social Support And Sexuality-Specific Social Support, Lee A. Golembiewski
Psychology Theses & Dissertations
Sexual minority (SM) college students continue to face greater mental health problems relative to their heterosexual peers (Woodford et al., 2014; Wilson & Liss, 2022). According to minority stress theory, SM individuals face distal (e.g., heterosexist discrimination) and proximal (e.g., expectations of rejection, internalized homophobia, and concealment) stressors related to their SM identity which can have negative effects on their mental health (Douglass & Conlin, 2020; Meyer, 2003). However, social support has been hypothesized to help protect against the effects of minority stress experienced by SM individuals (Cohen & Wills, 1985; Moody & Smith, 2013). Most of the existing research …
Predicting E-Cigarette Use Among Emerging Adults Using Perceived Social Norms And Outcome Expectancies, Stephen N. Hanson
Predicting E-Cigarette Use Among Emerging Adults Using Perceived Social Norms And Outcome Expectancies, Stephen N. Hanson
Psychology Theses & Dissertations
Despite low rates of combustible tobacco use rates among adolescents and young adults, e-cigarettes continue to gain popularity. A few factors have been shown to be related to e-cigarette use based on prior research. One such example is social enhancement expectancies. Additionally, greater perceptions of harm have been found to be inversely related to e-cigarette use such that those that expect increased risk to their health are less likely to report using e-cigarettes. I hypothesized that social enhancement expectancies would mediate the relationship between perceptions of social norms and e-cigarette dependence. I also hypothesized that perceived harm, such as greater …
Racial Differences In Tobacco Use And Risk Factors Among Young Adults: Roles Of Expectancies And Emotion Regulation, Laurel Brockenberry
Racial Differences In Tobacco Use And Risk Factors Among Young Adults: Roles Of Expectancies And Emotion Regulation, Laurel Brockenberry
Psychology Theses & Dissertations
African Americans experience higher mortality from lung cancer and other smoking-related diseases than Caucasian Americans (Kochanek et al., 2016) despite engaging in cigarette and e-cigarette use significantly less or at comparable rates to other racial groups (CDC, 2015; Schoeborn, 2013). During adolescence, smoking prevalence is lower among African Americans than Caucasian Americans, but there is a “cross-over effect” whereby smoking rates become similar later in adulthood (Belgrave et al, 2010). The mechanisms driving this effect are poorly understood. Thus, examining motivating factors for tobacco use, such as outcome expectancies and emotion regulation, may be especially illuminating for young adult African …

Psychology Theses & Dissertations
The purpose of this study was to examine the preliminary feasibility of an online, manualized, group-based, multi-component, cognitive behavioral therapy (CBT) treatment approach for the reduction of caregiver burden among family caregivers of persons with dementia. This study had five primary hypotheses: (1) the recruitment plan, as outlined within this study, would yield the target number of participants within a 12-month period; (2) the proposed group therapy protocol would produce a positive therapeutic climate, as operationalized by increased levels of perceived social support, perceived group cohesion, positive therapeutic alliance, and positive engagement; (3) this study would maintain adequate participant retention, …
The Effects Of Depression, Anxiety, And Stress On College Students: Examining The Role Of Mental Health Self-Efficacy On Willingness To Engage In Mental Health Services, Leeanna L. Golembiewski
The Effects Of Depression, Anxiety, And Stress On College Students: Examining The Role Of Mental Health Self-Efficacy On Willingness To Engage In Mental Health Services, Leeanna L. Golembiewski
Psychology Theses & Dissertations
Relative to younger ages, mental health problems are more prevalent among college students (Pedrelli et al., 2015) and nearly 20% of U.S college students are diagnosed each year with a mental health problem (Blanco et al., 2008). College students’ self-efficacy may influence mental health outcomes by impacting an individual’s decision to change their behavior and execute a course of action (Bresó et al., 2011). Mental health may also be influenced by the degree of willingness that an individual possesses, such that those who are more willing to seek mental health treatment are also more likely to follow through and seek …
Sleeping With The Enemy: Examining The Relationship Between Sleep And Pain In Post-9/11 Veterans, John L. Schwartz Jr.
Sleeping With The Enemy: Examining The Relationship Between Sleep And Pain In Post-9/11 Veterans, John L. Schwartz Jr.
Psychology Theses & Dissertations
United States veterans are a diverse group of individuals, yet as a result of their service, they share a unique set of customs, traditions, and values. Post-9/11 veterans are more likely to experience elevated levels of pain and poor sleep quality compared to their civilian counterparts; however, little is known about how beliefs related to veterans’ pain impact their sleep and how levels of pain acceptance influence the sleep-pain association. This study examined relationships between sleep and pain in a sample of 102 post-9/11 veterans. Results support associations between pain and sleep identified in other populations. Positive correlations were found …
The Role Of Athletic Identity In General Mental Health And Alcohol-Related Help-Seeking Intentions Of College Students, Michael Grant Young
The Role Of Athletic Identity In General Mental Health And Alcohol-Related Help-Seeking Intentions Of College Students, Michael Grant Young
Psychology Theses & Dissertations
Young adults are vulnerable to a range of mental health concerns and tend to drink in high quantities and tend to not seek help for these concerns. Specifically, college students involved in athletics tend to have low help-seeking rates—though help-seeking research for this population is relatively limited. Athletic identity (i.e., identification with the athlete role) is a relevant construct for examining this population, however little is known about its association with help-seeking beliefs and ideas. This study examines: (1) the association between athletic identity and help-seeking intentions for both mental health and alcohol use concerns, (2) the association between …
Body Dissatisfaction And Disordered Eating Among College Women’S Social Networks: An Investigation Of Perceived Changes Following A Dissonance-Based Body Image Intervention, Rachel I. Macintyre
Body Dissatisfaction And Disordered Eating Among College Women’S Social Networks: An Investigation Of Perceived Changes Following A Dissonance-Based Body Image Intervention, Rachel I. Macintyre
Psychology Theses & Dissertations
Body dissatisfaction is associated with numerous health consequences and is pervasive among college women. Effective interventions exist that reduce body dissatisfaction in college women by helping them resist sociocultural pressures to conform to the appearance ideal, such as the Body Project. Yet research is limited on whether social and behavioral processes help participants reduce their engagement in sociocultural appearance-ideal messages and contribute to the intervention’s effectiveness. The primary purpose of the present study was to examine these social and behavioral processes, including the changes in college women’s social networks associated with their participation in the Body Project. Undergraduate and graduate …
Burnout, Self-Efficacy, And Coping Strategies Among College Faculty, Jordan M. Ball
Burnout, Self-Efficacy, And Coping Strategies Among College Faculty, Jordan M. Ball
Psychology Theses & Dissertations
Due to the changing college environment, university faculty are faced with a serious burden to support their university. University faculty are expected to satisfy numerous job demands, and these demands in turn lead to burnout, a chronic response to job stressors. Burnout is an essential component of occupational research as it relates to other negative outcomes, such as turnover and decreased performance. Because of this, it behooves both faculty and universities to employ methods that decrease burnout. Research concerning other populations indicates that certain personal resources can decrease burnout. Therefore, the current study seeks to determine if coping strategies and …
A Model Of Individual, Relationship, And Societal Factors And Mental Health And Well-Being In Partnered Sexual Minority Women: The Central Role Of Relationship Satisfaction, Charlotte A. Dawson
A Model Of Individual, Relationship, And Societal Factors And Mental Health And Well-Being In Partnered Sexual Minority Women: The Central Role Of Relationship Satisfaction, Charlotte A. Dawson
Psychology Theses & Dissertations
Sexual minority women (SMW) are at increased risk for mental health disorders, substance abuse, and physical health problems compared to heterosexual women. For heterosexual individuals, romantic relationships have been found to be protective against a variety of health issues. Less research, however, has focused on the association between romantic relationships and health in same-sex couples. The purpose of this study was to examine the potential protective nature of being in a relationship for SMW and to test a model investigating the central role of relationship satisfaction in the association between individual, relationship, and societal factors and mental health and well-being …
The Effects Of Military Sexual Trauma And Depressive Symptoms On Reintegration, Rachel L. Davies
The Effects Of Military Sexual Trauma And Depressive Symptoms On Reintegration, Rachel L. Davies
Psychology Theses & Dissertations
Reintegration is a challenge for many veterans returning to civilian roles after military service. Difficulties range from an assortment of issues such as self-care to community participation. Military sexual trauma may be an experience that alters or changes veterans and result in difficulty in reintegration. Specifically, it was predicted that military sexual trauma would indirectly affect reintegration, via depressive symptoms. In addition, locus of control was predicted to play a role in how military sexual trauma impacts reintegration with external locus of control acting as a buffer. Participants were a cross-sectional community sample of both female veterans who reported having …
Coping Self-Efficacy As A Potential Moderator Of The Relationship Between Sexual Orientation And Negative Mental Health Outcomes, James M. Macchia
Coping Self-Efficacy As A Potential Moderator Of The Relationship Between Sexual Orientation And Negative Mental Health Outcomes, James M. Macchia
Psychology Theses & Dissertations
Sexual minority individuals (i.e., those who identify as a sexual orientation other than heterosexual) have consistently been linked to an increased risk of negative mental health outcomes. The process of coping can impact the content and severity of said outcomes, and one’s ability to cope is often predicted by the concept known as coping self-efficacy (i.e., one’s belief in his or her ability to cope). This study aimed to assess the effects of sexual orientation, coping self-efficacy, and their interactions on mental health by looking at different aspects of coping self-efficacy as potential moderating variables. Self-perceptions of coping skills were …
Investigating A Multimodal Approach To Clinical Diagnosis Of Mild Cognitive Impairment And Alzheimer’S Disease, Sean M. Flannery
Investigating A Multimodal Approach To Clinical Diagnosis Of Mild Cognitive Impairment And Alzheimer’S Disease, Sean M. Flannery
Psychology Theses & Dissertations
An estimated 5.8 million Americans suffer from dementia due to Alzheimer’s disease (AD), with that number projected to grow to 13.8 million by mid-century (Alzheimer’s Association, 2019). Mild cognitive impairment (MCI) describes the stage between normal cognitive decline that comes with aging and a dementia diagnosis (Peterson, 1999). Due to a lack of a cure or particularly effective treatment, a major goal of treatment is to focus on improving quality of life (Budson & Solomon, 2016). An early and accurate diagnosis can address this goal in a variety of ways. Despite the high prevalence and immense amount of research in …
Mindfulness And Its Impact On Adaptive Coping And Psychological Well-Being: An Intervention For Undergraduate Students, Charles Bradley Freligh
Mindfulness And Its Impact On Adaptive Coping And Psychological Well-Being: An Intervention For Undergraduate Students, Charles Bradley Freligh
Psychology Theses & Dissertations
The concept of mindfulness has been shown to positively impact psychological well-being, and one application of mindfulness-based interventions has been the development and implementation of courses specifically for college students, a population that has been shown to be particularly vulnerable to the negative impacts of stress. While these interventions have displayed beneficial outcomes, the mechanisms of how mindfulness exerts its impact remain unclear. One potential mechanism of mindfulness’ enhancement of well-being may be through its cultivation of an adaptive coping style in which an individual becomes more likely to approach and investigate stressors rather than avoid them. In this study, …
Personal Beliefs About The Effectiveness Of A Primary Seat Belt Law In Virginia Versus North Carolina, Rochelle A. Rushlow
Personal Beliefs About The Effectiveness Of A Primary Seat Belt Law In Virginia Versus North Carolina, Rochelle A. Rushlow
Psychology Theses & Dissertations
Seat belt law strength (primary versus secondary) affects the ability of law enforcement to enforce consistent seat belt use, especially in secondary seat belt law states. Certain demographics correlate with seat belt law effectiveness beliefs and overall seat belt use. The current study used an overall omnibus model to determine the strength of the relationship among demographics and beliefs in the effectiveness of primary seat belt laws. A survey was deployed to Mechanical Turk (MTurk) users who were Virginia or North Carolina residents, held a valid United States driver’s license, and were at least 18 years old. Three hundred twenty-four …
Popular Television’S Health And Safety Message: What Has Changed In The Past Generation?, Heather Ann Leon
Popular Television’S Health And Safety Message: What Has Changed In The Past Generation?, Heather Ann Leon
Psychology Theses & Dissertations
The assertion that television has an impact on viewers is well-supported in theory and empirical research. Hundreds of researchers have conducted hundreds of studies focused on limited, specific programming content or specific effects to contribute to this evidence. However, far fewer researchers have conducted broad, comprehensive programming content analysis. One exception is a 2005 study from Will et al. examining multiple health and safety behaviors including sexual activity, driving behaviors, intoxicating and unhealthy substance use, and violence depicted in the 1997/1998 primetime television season. Results of their research showed overall that primetime television promoted the perception that the observed health- …
The Bidirectionality Of Impulsivity And Alcohol Use: An Ecological Momentary Examination Among Emerging Adults, Amy L. Stamates
The Bidirectionality Of Impulsivity And Alcohol Use: An Ecological Momentary Examination Among Emerging Adults, Amy L. Stamates
Psychology Theses & Dissertations
Impulsivity is a robust risk factor for alcohol use among emerging adults (i.e., 18 to 25), but significant gaps remain in our understanding of the way that impulsivity relates to alcohol harms. Most prior research has been limited to between-level differences; thus, within-person variability in impulsivity at the momentary level and its bidirectional association with alcohol use has not been examined. Consequently, the present research used a 14-day ecological momentary assessment (EMA) design to: (1) determine momentary impulsivity as a predictor of subsequent alcohol use and problems; (2) examine the influence of alcohol use on subsequent impulsivity; (3) test socio-cognitive …
Comparing The Effects Of Mental Workload Between Visual And Auditory Secondary Tasks During Laparoscopy, James P. Corcoran
Comparing The Effects Of Mental Workload Between Visual And Auditory Secondary Tasks During Laparoscopy, James P. Corcoran
Psychology Theses & Dissertations
The purpose of this study was to test Wickens’ Multiple Resource Theory (MRT) by comparing performance and subjective workload on a visual-spatial secondary task with an auditory-spatial analog when paired with visual-spatial laparoscopic primary tasks. Two primary tasks were performed with a laparoscopic box trainer: a high workload task that consisted of transferring rings from one peg to another and a low workload task that consisted of grasping and placing large pencil erasers in a bowl. It was predicted that the visual-spatial secondary task would be more sensitive when paired with the laparoscopic primary task than the auditory analog. Findings …
Testing The Efficacy Of Transcranial Magnetic Stimulation (Tms) In Treating Depression In Patients With Cognitive Impairment, Daniel Robert Schaffer
Testing The Efficacy Of Transcranial Magnetic Stimulation (Tms) In Treating Depression In Patients With Cognitive Impairment, Daniel Robert Schaffer
Psychology Theses & Dissertations
The purpose of this study is to (1) examine the efficacy of Transcranial Magnetic Stimulation (TMS) in treating depression among individuals with cognitive impairment and (2) to examine if TMS is capable of facilitating cognitive improvements independent of mood improvements. Mild cognitive impairment (MCI) is often seen as a pre-clinical stage to dementia, and depressive disorders are highly prevalent among both MCI and dementia. There is a large body of research that has linked depressive disorders as a prodromal symptom of MCI and the later development of dementia. While some researchers debate whether or not this link between depression and …
Attention Deficit Hyperactivity Disorder With Comorbid Anxiety/Depression In Adults: Impacts On Neuropsychological Functioning, Cristina Valdivieso Bain
Attention Deficit Hyperactivity Disorder With Comorbid Anxiety/Depression In Adults: Impacts On Neuropsychological Functioning, Cristina Valdivieso Bain
Psychology Theses & Dissertations
ADHD comorbidity with other disorders is high in the adult population (over 44% of individuals carry a second diagnosis, 25% anxiety, 18.6% in depression). Separately, these disorders can impact scores on neuropsychological assessments. Little research has investigated how comorbidity among ADHD and other disorders impacts test scores collectively. Given high rates of comorbidity between ADHD and anxiety/depressive disorders and the potential impact on neuropsychological functioning, the current study examined how these comorbid disorders collectively impact cognition. Specifically, the present study investigated differences in full scale intelligence, general ability, and cognitive proficiency on the WAIS-IV between those diagnosed with ADHD only …
A Single Campus Study Of The Green Dot Bystander Intervention Program, Brittany F. Hollis
A Single Campus Study Of The Green Dot Bystander Intervention Program, Brittany F. Hollis
Psychology Theses & Dissertations
Sexual assault is a serious public health issue that is especially problematic on college campuses. To combat sexual violence on college campuses prevention programs have been instituted by many universities. One such prevention program, the Green Dot program, works to teach students what constitutes sexual violence and how to prevent it by increasing bystander intervention. The current study examined the effectiveness of Green Dot at a large southeastern university. The Theory of Planned Behavior (TPB) was used as the theoretical framework. TPB examines how efficacy, attitudes, and norms influence behavior. Students were recruited to participate in the Green Dot program …
The Relationship Of Early Class Start Times On Sleepiness And Driving Behaviors In An Emerging Adult Population, Jessica L. Fry
The Relationship Of Early Class Start Times On Sleepiness And Driving Behaviors In An Emerging Adult Population, Jessica L. Fry
Psychology Theses & Dissertations
Teenage driver sleepiness is a recent concern for preventing motor vehicle fatalities. Early school start times limit the amount of sleep teenage high school students acquire during the week and have been related to increased crash risk. The current study extends this finding to teenage and emerging adult college students. The author examined the link between sleepiness and teenage driving behaviors, including the relationship between school start times and sleepiness. In all, 536 participants were recruited to participate in an online survey assessing driving and sleep behaviors. Correlations and path analysis found that sleepiness fully mediated the relationship between early …
