Electroencephalographic Asymmetry, Emotion Regulation, And Their Relationships With Depression Risk, Aliza Jacob

Dissertations, Theses, and Capstone Projects

Background: Research investigating patterns of electroencephalographic (EEG) brain asymmetry aids our understanding of neural systems involved in the processing of emotion, motivation, and psychopathology. Withdrawal-motivated negative emotions characteristic of depression are associated with relative right prefrontal cortex (PFC) activity, whereas approach- motivated positive emotions are associated with relative left PFC activity. Styles of emotion regulation (ER), or modulation of the intensity and duration of emotional responses, are also associated with presence (e.g., suppression, or maladaptive ER) versus absence (e.g., cognitive reappraisal, or adaptive ER) of depression vulnerability. Most PFC asymmetry studies of emotion, depression, and/or ER rely upon EEG recorded …

Internal And External Attention In Autism Spectrum Disorder, Tehila Eilam-Stock

Dissertations, Theses, and Capstone Projects

Autism Spectrum Disorder (ASD) is a pervasive neurodevelopmental condition affecting individuals throughout the lifespan. Sensory hypersensitivity and superior perceptual acuity are well documented in individuals with ASD, and may indicate heightened orientation of attention to external stimuli, as attention can augment sensory perception. Recent evidence from mind-wandering research suggests that the ability to disengage attention from the external environment and direct it internally to self-generated mentation is crucial for adaptive cognition and behavior, as it allows for incorporation of past knowledge and experience in the interpretation of novel situations. We hypothesized that ASD is related to an imbalance between externally …

The Impact Of Mentalization And Self-Compassion On Psychological Adjustment In Adolescents, Jaleh Hamadani

Dissertations, Theses, and Capstone Projects

The following study was designed to look at the impact of Mentalization (or Reflective Functioning (RF)) as well as Mentalized Affectivity (MA) [comprised of Identifying, Processing, and Expressing] and Self-Compassion (SC) on psychological adjustment in adolescents. Psychological adjustment in this study was measured utilizing measures of psychological symptoms (internalizing and externalizing symptoms) and well-being.

While deficiencies in RF have been associated with increased psychological symptoms in clinical sample of adolescents, studies examining RF in community sample of adolescents have shown a mixed picture. Furthermore, no study to date has examined the impact of MA on psychological adjustment in …

Clinical Characteristics And Neuroanatomical Predictors Of Acute Antidepressant Outcome For Patients With Comorbid Depression And Mild Cognitive Impairment, Jeffrey N. Motter

Dissertations, Theses, and Capstone Projects

Background: Older adults presenting with both a depressive disorder (DEP) and cognitive impairment (CI) represent a unique, understudied population. The classification of cognitive impairment severity continues to be debated though it has recently been subtyped into late (LMCI) versus early (EMCI) stages. Previous studies have found associations between treatment outcome and both cortical thickness and white matter hyperintensities (WMH), though report inconsistent directionality and affected regions. In this study, we examined baseline clinical characteristics and neuroanatomical features as prognostic indicators for older adults with comorbid DEP and CI participating in an open antidepressant trial. EMCI is hypothesized to have greater …

Subjective Experience Of Autonomy And Psychological Well-Being: A Cross-Cultural Study With Korean American And European American Young Adults, Esther J. Lee

Dissertations, Theses, and Capstone Projects

This study aimed to explore whether parenting beliefs and practices that might promote academic or professional achievements also undermine aspects of psychological well-being. Specifically, the study focused on the relationship between the experience of subjective autonomy and psychological well-being measured in terms of self-esteem, flourishing, and life satisfaction. The sample consisted of 86 second-generation Korean Americans (KAs) and 99 European Americans (EAs) ages 25-35. Perceived parental autonomy support (versus psychological control) and perceived parental modernity (versus traditionalism) were also examined for group differences and associations with psychological well-being. As a group, KAs perceived greater parental psychological control and parental traditionalism …

Getting The Benefit Of The Doubt: The Effect Of Randomization Ratio On The Placebo Response, Taiki Matsuura

Dissertations, Theses, and Capstone Projects

Placebos are commonly employed in clinical trials as inactive treatments to which experimental treatments are compared against in order to control for psychological “noise.” Randomized double-blind placebo control studies are considered the “gold standard” in epidemiologic research because they can provide the strongest possible evidence of causation if designed correctly (Hulley, Cummings, Browner, & Grady, 2007). One phenomenon that poses a threat to the integrity of this evidence is the placebo response (PR), or referred to as the “placebo effect.” Expectancy is considered a central PR mechanism and boasts the most empirical support among all proposed mechanisms. Expectancy is not …

The Development Of Face Morphing Task To Assess Self Other Differentiation, Esen Karan

Dissertations, Theses, and Capstone Projects

Self-Other Differentiation (SOD) refers to a developmental process of acquiring a consolidated, integrated, and individuated sense of self. SOD develops at a) perceptual (e.g., facial perception) and b) representational (e.g., traits, mental states, and beliefs) levels. Impairments in representational SOD (R-SOD) are associated with many forms of psychopathology, particularly borderline personality disorder (BPD) and narcissistic personality disorder (NPD). Few studies to date have examined the perceptual aspects of SOD (P-SOD), which are hypothesized to develop from infancy onwards in tandem and in interaction with R-SOD. Given that the human face is one of the key characteristics that humans use to …

The Impact Of Racial Microaggressions And Major Discriminatory Events On Mental Health, Florence Lui

Dissertations, Theses, and Capstone Projects

The current study, a secondary data analysis, sought to determine the number and nature of latent groups for experiences of spectrum racial discrimination (i.e., both major and microaggressive racial discrimination) in a sample of emerging adults from a people of color (POC)-majority public university setting in the United States, and to understand the role of socio-demographic variables in defining each group. In addition, the study aimed to ascertain the extent to which endorsing spectrum racial discrimination experiences predicted anxiety and/or depression above the effects of general, non-race-related stress. Finally, the analyses gauged the mediating and/or moderating role of coping in …

The Social Cost Of Pain: Rejection Sensitivity, Social Rejection, And Cannabis Use In Young Adults, Naomi Dambreville

Dissertations, Theses, and Capstone Projects

Cannabis has been implicated in relieving distress and social pain, an important area of research in young adult samples, given the saliency of peer and social networks to addiction. Cannabis, via opioid pathways, has been shown to reduce, or potentially buffer, the effects of social pain and rejection. Thus, cannabis may be protective against the painful feelings of social stress, particularly for heavier or more frequent users. However, findings are not wholly positive, as other research indicates cannabis may blunt affective responses and impair social processing. The effects of cannabis use in young adults are understudied, as well as its …

Dermatoglyphic Measures In Relation To Depressive Symptoms Among Non-Clinical Adolescents And Young Adults, Yosefa A. Modiano

Dissertations, Theses, and Capstone Projects

Depressive disorders are highly prevalent and can be devastating. Increasingly, depressive symptomatology is understood from a dimensional perspective such that non- or sub-clinical presentations may share a similar etiology. Depression etiology is believed to include genetic and environmental factors that may contribute to underlying vulnerability (diathesis) by way of neurodevelopment. Birth cohort studies have provided empirical evidence of the relationship between prenatal insult and later experience of adverse outcomes, including increased risk for depressive disorders. Retrospective investigation of the possible influence of prenatal disturbance on later experience of depressive symptoms has methodological limitations. Dermatoglyphic measurements offer a more methodologically viable …

Assessment Of Third Wave Therapy Assumptions About The Relation Between Emotional Schemas And Psychoemotional Functioning, Emily Rachel Edwards

Dissertations, Theses, and Capstone Projects

Recent advancements in emotion theory propose that emotional schemas – individualized conceptualizations and beliefs about emotions – serve a fundamental function in guiding psychoemotional processes. These advancements have progressed alongside the development of third-wave therapies, which presume emotional schemas to be deeply involved in perpetuating psychological distress and emotional dysfunction. To critically assess the validity of this presumption, the current research proposed and evaluated an integrative model of psychoemotional functioning.

Two studies were completed using a combination of behavioral, performance-based, and self-report measures of emotional schemas and psychoemotional functioning. Though further research is needed, results suggest the integrated model of …

Does Ethnic Identity, In-Group Preference, And Acculturation Protect Latinas With A History Of Interpersonal Trauma From Developing Symptoms Of Ptsd?, Evelyn M. Ramirez

Dissertations, Theses, and Capstone Projects

Previous research suggests ethnic identity, a sense of belonging to a particular cultural group, may be protective against symptoms of post-traumatic stress disorder (PTSD). However, the role of ethnic identity, in-group preference (i.e., an individual’s preference for interactions with members of their own ethnic group) and acculturation (i.e., the level of comfort with the mainstream culture) have not been investigated as protective factors for Latinas with a history of interpersonal and sexual trauma. In this study, ethnic identity, in-group preference and acculturation were assessed via self-report on the Scale of Ethnic Experience in two samples of undergraduate Latina and non-Latina …

Investigating The Feasibility Of Advanced Law Enforcement Resilience Training (A.L.E.R.T.): An Innovated And Practical Intervention To Enhance Police Mindfulness And Resilience, Stephanie B. Stern

Dissertations, Theses, and Capstone Projects

Policing is thought to be one of the most stressful occupations. Without effective strategies to cope with chronic work-related stress, police are vulnerable to developing mental and physical health problems. The police literature and research highlights the need for proactive, evidence-based interventions to help police maintain their resilience throughout their careers. The current study sought to bridge a gap between police literature, research and practice by developing and testing the feasibility of using the Advanced Law Enforcement Resilience Training (A.L.E.R.T.) mobile app to help police learn and practice mindfulness skills after engaging in a brief in-person training. Using a pre-test, …

Examining The Use Of Hebephilia And Paraphilia Non-Consent In Sexually Violent Predator (Svp) Evaluations, Nicole Graham

Dissertations, Theses, and Capstone Projects

Sexually violent predator (SVP) legislation requires, in part, that an individual has a mental abnormality which causes difficulty in controlling sexual behavior. Previous research has found paraphilia not otherwise specified (NOS) to be one of the most prevalent diagnoses proffered in SVP evaluations. Since these studies, however, the Diagnostic and Statistical Manual (DSM) has updated the paraphilia NOS diagnosis in two ways. First, this diagnosis has been divided into two new diagnoses—other specified paraphilic disorder (OSPD) and unspecified paraphilic disorder. Second, OSPD requires an added specifier to indicate the individual’s source of sexual arousal. To date, no study has systematically …

Examining The Effects Of A Multi-Component Neurocognitive Intervention For School-Aged Children With Co-Occurring Adhd And Reading Difficulties, Alyssa L. Chimiklis

Dissertations, Theses, and Capstone Projects

Objective: Children with attention deficit hyperactivity disorder (ADHD) frequently exhibit impairments in neurocognitive pathways (i.e., deficits in sustained attention, response inhibition, processing speed, working memory, and cognitive flexibility). There is also extensive support indicating that youth with co-occurring ADHD and reading difficulties share pathological pathways and exhibit deficits in executive functions. Neither behavioral nor pharmacological interventions have been able to fully address executive dysfunction and/or reading deficits in this population. Computerized neurocognitive training interventions have been explored as a treatment alternative for youth with pure ADHD and have demonstrated some merit. Conceptually, computerized neurocognitive training programs that target overlapping pathways …

Perceptions Of Sexual Violence: An Investigation Of Sexual Harassment, Sexual Coercion, And Sexting, Jennifer J. Mcmahon

Dissertations, Theses, and Capstone Projects

Perpetration of sexual violence is a serious concern in the US, with research indicating that a substantial portion of the population has experienced some type of sexual victimization. There is sparse research that examines perceptions and judgments of sexually inappropriate behaviors, and existing research does not take into account the impact of individual differences and contextual factors. This study examined whether individuals recognize different forms of sexual harassment, sexual coercion, and sexting as inappropriate, and how these perceptions are affected by sex, age, and relationship status. A mixed sample of undergraduate students and adults within the community completed an online …

Relational Processes In Support-Related Communication Among Young Adults With Cancer, Kathleen Darabos

Dissertations, Theses, and Capstone Projects

Despite decades of studies reporting positive associations of social support with cancer-related quality of life, little attention has been paid to understanding how relational qualities (e.g., self-disclosure, perceived support member disclosure, perceived support member responsiveness) of cancer-related support exchanges might influence psychological adjustment and intimacy among young adults with cancer. Further, little attention has been paid to understanding how young adults with cancer communicate with their social support networks among different modes of communication [(face-to-face vs. technology-related (e.g., text message, social media)] remains poorly understood. Questionnaire data from 45 young adults with cancer combines these two separate but related literatures …

Childhood Neglect And Risk Of Revictimization By An Intimate Partner: A Prospective Investigation Of Mediational Pathways, Rebecca M. Spizzirri

Dissertations, Theses, and Capstone Projects

Childhood maltreatment increases risk of revictimization in adulthood, although knowledge is limited. Very few studies focus on children with histories of neglect or include males. In addition, while some studies have begun to examine potential pathways from childhood victimization to adult revictimization, there is heavy reliance on data from cross-sectional or short-term longitudinal studies. This dissertation examines data from a large prospective cohort design study to examine potential mediators between childhood neglect and revictimization by an intimate partner in adulthood. Children with official records of neglect experienced before age 12 and non-maltreated children matched on the basis of age, sex, …

Mindfulness In Medicine: Modified Mindfulness-Based Stress Reduction (Mbsr) Program Among Future Doctors, Virtue Sankoh

Dissertations, Theses, and Capstone Projects

Medical trainees are at particular risk for stress-related illness, including mental health problems such as suicidal ideation, substance abuse, and mood disorders. A vast literature on mindfulness-based stress reduction (MBSR), consisting of mindfulness education and structured meditative practices, has consistently demonstrated that MBSR and related mindfulness-based interventions improve mental and physical health, as well as one’s overall sense of well-being. Moreover, theorists and researchers have begun to suggest further that mindfulness plays a particular role in social cognition, or social-emotional learning. Medical schools have long been interested in ways to improve the “soft skills” related to interpersonal connectedness that are …
