Adult Attachment Interview Classification: Comparing Two Coding Systems, Patricia M. Hastings Jan 2021

Adult Attachment Interview Classification: Comparing Two Coding Systems, Patricia M. Hastings

Antioch University Dissertations & Theses

Research on the Adult Attachment Interview (AAI) provides an opportunity to study the ways in which early childhood relational experiences might influence an individual over a lifetime. It is not yet clear, however, whether results from different coding systems for the AAI are equally useful. The first purpose of this study was to compare attachment classification distributions obtained from coding AAIs with the Berkeley and Dynamic-Maturational Model (DMM) coding systems. The second purpose was to explore whether AAI classifications derived from the Berkeley or DMM system were more strongly associated with mother and mother-child dyad outcome variables. Participants were a …


Examining The Relationship Between Five Factors Of Mindfulness And Parenting Stress: A Correlational Study Of New Mothers, Jessica L. Lazaro Jan 2021

Examining The Relationship Between Five Factors Of Mindfulness And Parenting Stress: A Correlational Study Of New Mothers, Jessica L. Lazaro

Antioch University Dissertations & Theses

It can be tempting to want to dissociate from the stress of parenting. The implication being that the early years of parenthood are meant to simply be endured. In contrast, mindfully embracing all aspects of parenthood, including the difficult moments, may allow the appreciation of beauty, growth, and connection, which is so essential to the human experience, especially as it relates to the parent-child relationship. As the popularity of mindfulness research increases, so does the information we have about using it with parents in general, and mothers in particular. The current study explores what, if any, relationship exists between levels …


Self-Concept, Healthcare, And Leadership: Understanding The Lived Experiences Of Physician Leaders In Urban Community Healthcare Centers, Eric James Charlton Jan 2021

Self-Concept, Healthcare, And Leadership: Understanding The Lived Experiences Of Physician Leaders In Urban Community Healthcare Centers, Eric James Charlton

Antioch University Dissertations & Theses

Reducing disparities in health services delivery and outcomes is a continued challenge. The consistence of healthcare disparities, despite advances in medical technology and increased awareness of the problem, poses an ongoing test to the nation. There is a growing body of work that demonstrates providing access to good primary care may be the most effective intervention at hand. For over 40 years, community health centers have been providing quality, comprehensive primary care focusing on reducing health outcome disparities. Increased awareness is now emphasizing primary care elimination of health disparities within disadvantaged, underserved populations. A major failing of the system that …


The Risks For Eating Disorders/Disordered Eating In Refugee & Immigrant Experiences And The Imperative Of Culturally Alert Screening, Chantal A. Bushelle Jan 2021

The Risks For Eating Disorders/Disordered Eating In Refugee & Immigrant Experiences And The Imperative Of Culturally Alert Screening, Chantal A. Bushelle

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Eating Disorders (ED)/Disordered Eating (DE) largely remain outside of global mental health agendas. There are limited data on the epidemiology EDs/DE in refugee and immigrant populations, and there is a paucity of research on refugee and immigrant experiences of EDs/DE. Study of acculturation issues in refugee and immigrant populations have historically missed investigating what role and impact experiences of stress and trauma (e.g., historical, chronic) along with cultural change and transition may have on their food attitudes and eating behaviors. While there has been some study of eating habits within refugee and immigrant populations, the focus is typically on food …


Encountering Death: A Training Proposal For Psychologists Addressing Death Anxiety And End-Of-Life Care, Bridget Kromrey Jan 2021

Encountering Death: A Training Proposal For Psychologists Addressing Death Anxiety And End-Of-Life Care, Bridget Kromrey

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

Inward reflection and knowing the self are an essential element to becoming a psychologist and is crucial when encountering themes of death and dying in psychotherapy. There are significant gaps in curriculum and training regarding death anxiety and end-of-life care for psychology trainees and psychologists despite psychologists’ growing presence in this type of work. The following paper will explore historical and current day theories of death anxiety and death education. It will also demonstrate the gaps in training for psychologists in the areas of death anxiety and end-of-life care and describe the need for this type of training to be …

Research Datasets

Combined data of three studies (N=164; 121 and 236 respectively) that investigated whether the voluntariness of apologies influenced recipients’ perception of the sincerity of apologies; acceptance of apologies; willingness to forgive offenders; and intended retributive behavior towards offenders.


Attitudes And Knowledge Of Autism Spectrum Disorder Among Australian Undergraduate Psychology Students, Tiffany Williamson Jan 2021

Attitudes And Knowledge Of Autism Spectrum Disorder Among Australian Undergraduate Psychology Students, Tiffany Williamson

Research Datasets

Autism Spectrum Disorder (ASD) has generated much research interest in recent times due to a soaring increase in diagnosis rates and a movement to recognise ASD as a cognitive style, rather than a cognitive deficit. Psychologists are responsible for the timely and accurate diagnosis of ASD and supporting clients on the spectrum with general mental health care. Undergraduate psychology students may go on to further study to become registered psychologists or choose to pursue other careers in mental health care and support work in which they will likely have contact with members of the autistic community. However, little research into …


Dimensional Latent Structure Of Icd-11 Posttraumatic Stress Disorder, Complex Ptsd, And Adjustment Disorder: Evidence From Ghana, Kenya, And Nigeria, Ruby Charak, Ines Cano-Gonzalez, Mark Shevlin, Menachem Ben-Ezra, Thanos Karatzias, Philip Hyland Jan 2021

Dimensional Latent Structure Of Icd-11 Posttraumatic Stress Disorder, Complex Ptsd, And Adjustment Disorder: Evidence From Ghana, Kenya, And Nigeria, Ruby Charak, Ines Cano-Gonzalez, Mark Shevlin, Menachem Ben-Ezra, Thanos Karatzias, Philip Hyland

Psychological Science Faculty Publications

With the release of ICD-11 in 2018, there has been a surge in studies examining the nosology of mental disorders, including disorders associated with stress, namely, posttraumatic stress disorder (PTSD), complex PTSD (CPTSD), and adjustment disorder (AjD). Few studies have examined the same in low- and middle-income countries that have disproportionate levels of exposure to trauma and stressors and are under-resourced in mental health services. The present study examined the latent factor structure of a joint model comprising PTSD, CPTSD, and AjD symptoms and their association with stressful and traumatic life events to assess the degree of distinctiveness between these …


Psychometric Properties Of The Contextual Body Image Questionnaire For Athletes: A Replication And Extension Study In Female Collegiate Athletes, Tiffany Stewart, Lisa S. Kilpela, Nicole Wesley, K. Baule, Carolyn Becker Jan 2021

Psychometric Properties Of The Contextual Body Image Questionnaire For Athletes: A Replication And Extension Study In Female Collegiate Athletes, Tiffany Stewart, Lisa S. Kilpela, Nicole Wesley, K. Baule, Carolyn Becker

Psychology Faculty Research

Background

Although the link between body dissatisfaction and eating disorder (ED) pathology is well-established in general female samples, less is known about contextual body image (CBI) among female athletes. CBI refers to female athletes’ body image concerns in two contexts: sport and daily life. The Contextual Body Image Questionnaire for Athletes (CBIQA) measures four dimensions of body image (Appearance, Thin-Fat Self-Evaluation, Thin-Fat Others’ Evaluation, and Muscularity) in both contexts. In a sample of female collegiate athletes, this study sought to A) investigate the psychometric properties of the CBIQA, B) examine the cross-sectional relation of CBI with ED pathology and negative …


Binge Eating Among Older Women: Prevalence Rates And Health Correlates Across Three Independent Samples, Salomé A. Wilfred, Carolyn Black Becker, K. E. Kanzler, N. Musi, S. E. Espinoza, Lisa S. Kilpela Jan 2021

Binge Eating Among Older Women: Prevalence Rates And Health Correlates Across Three Independent Samples, Salomé A. Wilfred, Carolyn Black Becker, K. E. Kanzler, N. Musi, S. E. Espinoza, Lisa S. Kilpela

Psychology Faculty Research

Background: Emerging research indicates that binge eating (BE; consuming unusually large amounts of food in one siting while feeling a loss of control) is prevalent among older women. Yet, health correlates of BE in older adult populations are poorly understood. The original study aimed to investigate BE prevalence, frequency, and health correlates in a sample of older adult women. Based on results from this first study, we then sought to replicate findings in two additional samples of older adult women from separate studies.

Method: Using self-reported frequencies of BE from three separate samples of older women with very different demographics, …


The Contribution Of Adverse Childhood Experiences To The Interplay Between Insecure Attachment Characteristics, Trait Emotional Intelligence, Difficulties In Emotion Regulation, And Personality Organization, Kseniia Gvozdieva Jan 2021

The Contribution Of Adverse Childhood Experiences To The Interplay Between Insecure Attachment Characteristics, Trait Emotional Intelligence, Difficulties In Emotion Regulation, And Personality Organization, Kseniia Gvozdieva

Dissertations and Theses

There are well-established connections between unfavorable attachment experiences and subsequent personality pathology. Individuals with adverse attachment experiences and those with personality pathology have been found to have difficulty with emotional awareness and emotion regulation. Attachment characteristics inform emotional intelligence and emotion regulation, while emotional intelligence and emotion regulation capacities can be protective against personality pathology and serve as a potential mechanism of positive change in one’s attachment. Complex trauma disrupts attachment and the subsequent development of emotional intelligence, emotion regulation, as well as personality structure.

In this dissertation, we examine the ways in which individual attachment patterns can be linked …


Examining Cultural Orientation As A Moderator: Attachment Style, Forgiveness, And Depression, Linghsi Liu Jan 2021

Examining Cultural Orientation As A Moderator: Attachment Style, Forgiveness, And Depression, Linghsi Liu

Dissertations and Theses

The purpose of this study was to examine the moderating role of cultural orientation on the relation between attachment style and forgiveness and between forgiveness and depression. It was hypothesized that a secure attachment style would be associated with greater dispositional forgiveness of both self and others. Specifically, for those high in collectivism, insecure attachment will be associated with greater other-forgiveness and for those high in individualism, insecure attachment will be associated with greater self-forgiveness. It was also predicted that self and other forgiveness would be associated with fewer depressive symptoms. Specifically, for those high in collectivism, other forgiveness will …


Does Social Media Promote Disordered Eating?, Carly Feldstein Jan 2021

Does Social Media Promote Disordered Eating?, Carly Feldstein

Dissertations and Theses

Hispanic people are the largest and fastest-growing minority group in the U.S. with a total of 18.5% of the U.S population being of Hispanic descent (United States Census Bureau, 2020). Although eating disorders (ED), particularly those involving binge eating, comprise a significant health concern, EDs are often overlooked in the Hispanic culture (Higgins et al., 2016; Opara & Santos, 2019). Hispanic individuals have comparable rates of anorexia nervosa, bulimia nervosa, and an even higher rate of binge eating disorders compared to non- Hispanic (NH) White individuals (Higgins et al., 2016). Within Hispanic adults, the lifetime prevalence of EDs is higher …


Exploring A Mediational Model Of The Relationship Between Skin Color And Mate Selection In Desi Young Adults, Rabiya Ahmed Jan 2021

Exploring A Mediational Model Of The Relationship Between Skin Color And Mate Selection In Desi Young Adults, Rabiya Ahmed

Dissertations and Theses

Skin color bias is present in South Asia and is especially apparent within the Desi (i.e., South Asian) marriage market, where explicit preferences for fair-skinned marital partners are made and lighter skin is perceived as more attractive. It is also known that, through the halo effect, attractive people are perceived to possess positive personality traits. The present study aimed to determine if skin color is associated with long-term mate preference among U.S.-based Desi adults as it is among Desi in South Asia, and if so, if that relationship is mediated by perceived attractiveness. It also aimed to determine if, in …


Timing Of Sexual Minority Identity Developmental Milestones And Well-Being Among Three Generations Of Gay Men, Joseph R. Hillesheim Jan 2021

Timing Of Sexual Minority Identity Developmental Milestones And Well-Being Among Three Generations Of Gay Men, Joseph R. Hillesheim

Dissertations and Theses

Social and political changes during recent decades have contributed to a more accepting environment for sexual minorities (non-heterosexual individuals) in the U.S., but recent evidence suggests that these shifts may create a “developmental collision” for younger generations (Meyer et al., 2021; Russell & Fish, 2019). Younger generations of sexual minorities “come out” and reach other sexual identity milestones earlier than older generations, and earlier timing of sexual identity development may contribute to increased vulnerability to stigma. The present study aimed to contribute to limited research on the relationship between the timing of sexual identity development milestones and well-being among three …


Protecting Civilians In Un Peace Operations: The Need For Enhanced Training, Allison S. Haddad Jan 2021

Protecting Civilians In Un Peace Operations: The Need For Enhanced Training, Allison S. Haddad

Dissertations and Theses

The present study shows that the protection of civilians (POC) tasks implemented in multiple United Nations (UN) peace operations have not always been executed as intended and, as a result, are accompanied by a number of dysfunctions. Among these dysfunctions are inadequate community engagement, peacekeeper misconduct stemming from the lack of proper training mechanisms, and lack of resources. In consideration of these issues, UN peace operations would profoundly benefit from enhancements offering plausible and beneficial change to the field. Such changes involve the responsibility of the UN, the responsibility of national actors, field implementations, and the psychological well-being of peacekeepers. …


Reading In Kapampangan, Filipino, And English: A Look At Multilingual Children In An Economically Challenging Philippine Community, Portia Padilla Jan 2021

Reading In Kapampangan, Filipino, And English: A Look At Multilingual Children In An Economically Challenging Philippine Community, Portia Padilla

Theses and Dissertations (Comprehensive)

The present studies advance current understanding of the skills and processes involved in multilingual reading, especially in less researched alphabetic languages. These studies examined whether the dominant models in reading in English can explain the reading processes involved among low-income multilingual speakers of Kapampangan (L1), Filipino (L2), and English (L3) in the Philippines, a developing country. Kapampangan and Filipino use the same Roman alphabet that English uses. However, these two languages have transparent orthographies while English has an opaque orthography.

Study 1 examined the psycholinguistic grain size theory within the context of multilingual reading. There were three hundred twenty-six children …


Who Is The Stranger Really? A Reluctant Autoethnography Of The Strange Situation Procedure, Tara Yazdani Jan 2021

Who Is The Stranger Really? A Reluctant Autoethnography Of The Strange Situation Procedure, Tara Yazdani

Theses and Dissertations (Comprehensive)

This paper aims to review the cross-cultural application of attachment theory as a western model of thought and practice. That is, this research aimed to recognize and question how embedded attachment theory has become in programming and education within North American academic and practical arenas. In applying the Strange Situation Procedure (SSP) to a limited sample of Eritrean dyads, important considerations and questions arose regarding the cross-cultural application of this protocol. The aims of this research shifted toward further exploring these considerations and questions, due to the global COVID-19 pandemic. Specifically, the new research aim emphasized how to inform future …


Is It Just A Dream? How Attributions For Successful And Unsuccessful Social Mobility Attempts Maintain The Myth Of The American Dream, Erin Shanahan Jan 2021

Is It Just A Dream? How Attributions For Successful And Unsuccessful Social Mobility Attempts Maintain The Myth Of The American Dream, Erin Shanahan

Theses and Dissertations (Comprehensive)

Despite rising inequality making upward social mobility difficult, faith in the American Dream persists. Why is this the case? In six studies (five pre-registered), we demonstrate that in scenarios where hard work and ability are held constant, people praise the hard work and talent of individuals who successfully move up the social ladder while derogating these same characteristics among individuals who do not; a pattern of attributions which is likely to reinforce the American Dream. Further, conservatives explain mobility failure particularly in terms of personal shortcomings whereas liberals look to systemic disadvantages, attributions that in turn predicted lowered and heightened …


Mother-Child Shared Story Telling Of Wordless And Worded Picture Books: A Within-Subject Design Study Of Preschool Children, Katherine Reid, Alexandra Gottardo Jan 2021

Mother-Child Shared Story Telling Of Wordless And Worded Picture Books: A Within-Subject Design Study Of Preschool Children, Katherine Reid, Alexandra Gottardo

Theses and Dissertations (Comprehensive)

Issues pertinent to developmental psychology and education often intersect. For example, both literatures can inform the assessment of differences in early literacy and school readiness, as well as how to bridge the literacy gap for children coming from different backgrounds. In times of COVID-19, it is especially important that we research the impact of strategies that are accessible to all, and can be utilized both in the home, and in more formal learning environments. This study assessed how the use of wordless picture books impacted the quality and quantity of language output, and engagement in dialogue between mother and child. …


How To Increase Elaboration Levels: An Adapted Elaboration Likelihood Model, Alex Mcdonald Jan 2021

How To Increase Elaboration Levels: An Adapted Elaboration Likelihood Model, Alex Mcdonald

CMC Senior Theses

Persuasion is a topic that has been debated for centuries, yet scientific literature surrounding the topic has been almost non-existent until 50 years ago. A popular persuasion model thus far, the Elaboration Likelihood Model, provides a framework for studying persuasion but lacks ease of application. I suggest an improvement to the model by including self-referencing and interaction to clarify how to apply the research and provide a real-world application with this adapted model.


Medical Knowledge As A Recalcitrant Epistemological System: An Application Of Standpoint Epistemology In The Analysis Of Marginalization Within U.S Healthcare, Abby Deshazo Jan 2021

Medical Knowledge As A Recalcitrant Epistemological System: An Application Of Standpoint Epistemology In The Analysis Of Marginalization Within U.S Healthcare, Abby Deshazo

CMC Senior Theses

Research on healthcare disparities outside the field of epistemology tend to miss the true origins of oppressions imposed on marginalized individuals by the U.S healthcare system. This happens because of the false belief that these oppressions are reducible to social or political oppressions. By employing the perspective of a standpoint epistemologist, we can better identify the origins of these oppressions and subsequently consider more appropriate solutions. The standpoint epistemologist’s perspective (1) provides an intuitive case for the role individuals’ schemas play in the evaluation of what healthcare professionals know; (2) situates medical knowledge within epistemology, leading us to …


Sleep Consistency And Its Relation To Inflammation: Identifying The Role Of Emotional Regulation, Caitlyn Louzado Jan 2021

Sleep Consistency And Its Relation To Inflammation: Identifying The Role Of Emotional Regulation, Caitlyn Louzado

CMC Senior Theses

Sleep duration, quality, and consistency are associated with well-being and productivity. College students struggle to achieve the right balance of sleep and research demonstrates how this has severe repercussions on their physical health academic performance. The effects of sleep consistency interact with emotional regulation (ER). This observational study investigates the relationship between all three sleep characteristics and inflammation, while exploring the mediating and moderating role of ER. Participants included 138 undergraduate students (Females= 81 Males= 57). ER and sleep quality were measured through self-reported questionnaires and inflammation through blood spot analysis. Sleep consistency and duration were assessed using an Acti-Watch. …


Seeing Through Woke-Washing: Effects Of Projected Diversity Values And Leader Racial Diversity On Equity In Workplace Outcomes, Adrienne M. Kafka Jan 2021

Seeing Through Woke-Washing: Effects Of Projected Diversity Values And Leader Racial Diversity On Equity In Workplace Outcomes, Adrienne M. Kafka

CMC Senior Theses

The presence of multicultural values, emphasizing the appreciation of distinct cultural identities in companies’ promotional materials, versus colorblind values, which minimize cultural distinctions, may affect Black/Hispanic/Latinx (BHL) vs White individuals’ cognitive ability employment selection test scores and likelihood of applying to an organization differently depending on the company’s demonstrated leader racial diversity (LRD). Participants (N = 419), recruited via Amazon MTurk, read a hypothetical job application call and mission statement with a specific diversity ideology emphasized (multiculturalism, colorblind, control, Black Lives Matter (BLM)) and viewed headshots of the company C-suite either with low LRD (mostly White) or high LRD before …


A Proposal To Develop And Pilot-Test The Effects Of A Culturally Adapted Stigma Intervention For Latinos, Sandy Ahumada Jan 2021

A Proposal To Develop And Pilot-Test The Effects Of A Culturally Adapted Stigma Intervention For Latinos, Sandy Ahumada

CMC Senior Theses

The bulk of research examining barriers to mental health services (MHS) for Latinos focuses on financial obstacles such as socioeconomic status and insurance coverage. Unfortunately, less work has been done on cultural barriers such as stigma. The purpose of this proposed study is to develop and pilot-test a culturally adapted contact intervention for Latinos that reduces stigma and increases help-seeking intentions. This study will test the differential efficacy of utilizing psychoeducation with the newly developed interpersonal contact intervention (PIC) as opposed to psychoeducation (P) only. Participants (n=324) will fill out pre- (T1), post- (T2), and 1-week follow-up (T3) …


The Effects Of Humor When Coping With Stress, Rahmel Dixon Jan 2021

The Effects Of Humor When Coping With Stress, Rahmel Dixon

CMC Senior Theses

Although humor is often used in professional, social, and political settings, its empirical importance is usually laughed at. I argue that scholars should give more attention to the topic. Building on prior research, the present work will explore the relationship between stress relief and the use of humor. Specifically, it will reveal the usage of humor to cope among historically stressed groups of people. Lastly, as stress and marginalization are linked, the study will also look at the relationship between a racially marginalized group, Black people, and their use of humor to relieve stress or cope.


Developing Culturally Versatile Leadership: Harnessing The Potential Of An Integrated World Through Global Managerial Talent, Uddhav Gupta Jan 2021

Developing Culturally Versatile Leadership: Harnessing The Potential Of An Integrated World Through Global Managerial Talent, Uddhav Gupta

CMC Senior Theses

The world today is more integrated than ever before, with international trade and multinational corporations being a prominent part of global commerce. To lead successfully through such globalization, leaders must bring global mindsets and perspectives to their organizations to navigate critical differences in behaviors and worldviews by each unique country or culture. This study explores whether global, cross-cultural leaders make better decisions which ultimately lead to better outcomes for global corporations by exploring the relationship between cross-cultural leaders and successful organizations as measured by customer satisfaction, employee engagement and development, innovation, social responsibility, financial strength, and stock performance. This study …


Viability Of Physiologically Timed Relaxation Interventions In Children With Asd, Nicholas Mendez Jan 2021

Viability Of Physiologically Timed Relaxation Interventions In Children With Asd, Nicholas Mendez

CMC Senior Theses

Autism Spectrum Disorder (ASD) is an increasingly common developmental disorder that changes how people experience the world and affects individuals’ social interactions and often leads to many adverse behaviors. Current literature dictates that a primary contributor to these adverse behaviors is that those with ASD have difficulty determining their own emotional states and determining the physiological signals that their body sends them. A study by Dr. Sarabadani et al. determined that it was possible to monitor the physiology of an individual with ASD and correlate certain signals to emotions, such as stress. These findings indicate the feasibility of establishing a …


Challenges Within The Education System: An In-Depth Analysis Of The School To Prison Pipeline In The United States, Roxanne Camarena Castillo Jan 2021

Challenges Within The Education System: An In-Depth Analysis Of The School To Prison Pipeline In The United States, Roxanne Camarena Castillo

CMC Senior Theses

Many scholars have hypothesized the existence of a school to prison pipeline (STPP) – a phenomenon that describes how particular school policies and practices have inadvertently created a pathway from schools to the juvenile criminal system. The pipeline disproportionately affects certain communities and has serious short- and long-term consequences for students. This paper explores the validity of the hypothesized pipeline and examines three underlying mechanisms: zero-tolerance policies, school safety, and school culture. After reviewing the research literature on these three mechanisms, I conclude that there is evidence for both STPP risk and STPP protective factors embedded within the school system. …


Association Between Toxoplasma Gondii Seropositivity And Serointensity And Brain Volume In Adults: A Cross-Sectional Study, Bruce L. Brown, Lance D. Erickson, Shawn D. Gale, Dawson W. Hedges Jan 2021

Association Between Toxoplasma Gondii Seropositivity And Serointensity And Brain Volume In Adults: A Cross-Sectional Study, Bruce L. Brown, Lance D. Erickson, Shawn D. Gale, Dawson W. Hedges

Faculty Publications

The intracellular protozoal parasite Toxoplasma gondii has been associated with worsened cognitive function in animal models and in humans. Despite these associations, the mechanisms by which Toxoplasma gondii might affect cognitive function remain unknown, although Toxoplasma gondii does produce physiologically active intraneuronal cysts and appears to affect dopamine synthesis. Using data from the UK Biobank, we sought to determine whether Toxoplasma gondii is associated with decreased prefrontal, hippocampal, and thalamic gray-matter volumes and with decreased total gray-matter and total white-matter volumes in an adult community-based sample. The results from adjusted multivariable regression modelling showed no associations between Toxoplasma gondii and …
