Introduction To Infant Early Childhood Mental Health And Trauma Training Program, Irene Rosaly Cortez Jun 2022

Introduction To Infant Early Childhood Mental Health And Trauma Training Program, Irene Rosaly Cortez

Loma Linda University Electronic Theses, Dissertations & Projects

This program aims to understand the lack of infant-early childhood trauma-informed care training for mental health clinicians. The current efforts to enhance mental health clinicians’ therapeutic knowledge and awareness through the development of the CCCT with the emphasis on trauma-informed care show significance to treat infant-early childhood trauma. Due to children’s susceptibility to trauma and developmental vulnerability, if trauma remains unaddressed, there are long lasting negative effects throughout their adulthood, as shown through the ACE’s study. Furthermore, the program’s theoretical framework encompasses Attachment Theory with the integration of the Theory of Neuroscience, Bowen family systems theory, Reflective Practice Model, and …

The Importance Of Timing In Repeated Traumatic Brain Injury, Willie L. Hardeman Iii Apr 2022

The Importance Of Timing In Repeated Traumatic Brain Injury, Willie L. Hardeman Iii

Loma Linda University Electronic Theses, Dissertations & Projects

Repeated closed-head traumatic brain injury (rTBI) can result in serious consequences, such as the development of neurodegenerative diseases like Alzheimer’s Disease (AD), chronic traumatic encephalopathy (CTE), and many others. This study characterizes the consequences of injury timing in a Drosophila melanogaster model of rTBI. Specifically, each fly was subjected to 4 strikes with a modified “high impact trauma” (HIT) device. The strikes were separated by either 5 minutes, 2 hours, 4 hours, or 36 hours. These inter-strike intervals theoretically provided an opportunity to study outcomes of repeated brain injury during times of unresolved rTBI mechanisms. Half of the flies were …


Factors Contributing To The Recognition Of A Potential Nonsexual Multiple Relationship, Nikki Patel Mar 2022

Factors Contributing To The Recognition Of A Potential Nonsexual Multiple Relationship, Nikki Patel

Loma Linda University Electronic Theses, Dissertations & Projects

Clinical psychologists encounter situations for which no prescriptive professional standards exist, necessitating therapists’ judgment to determine an appropriate course of action. This study examines the first step of therapists’ decision-making process—recognition of the potential for a nonsexual multiple relationship. Based on the existing literature and previous empirical findings, our hypotheses are that (1) therapist sex (female), higher scores on the PAQ Expressivity (femininity) scale, higher scores on the VIA-IS-V3 Self-control scale, and participants’ ranking Nonmaleficence as the most important ethical principle would be significantly (positively) predictive of Recognition scores, (2) higher scores on the PAQ Instrumentality (masculinity) scale, higher scores …


Provider Attributions, Emotions, & Responses To Patients With Poor Diabetes Management, Kelly Marie Mackenzie Dec 2021

Provider Attributions, Emotions, & Responses To Patients With Poor Diabetes Management, Kelly Marie Mackenzie

Loma Linda University Electronic Theses, Dissertations & Projects

Type 2 diabetes mellitus (T2DM) presents challenges to both patients and healthcare providers. While researchers have begun to understand the patient-specific difficulties associated with diabetes management, less is known about how providers perceive and experience patients who are struggling to manage their T2DM, particularly in the context of training environments. The aim of the present study was to better understand the cognitions, emotions, and behavioral responses of medical trainees when presented with a clinical vignette of a patient with poor diabetes self-care. To this end, the research was guided by attribution-emotion models of helping and avoidance. It was hypothesized that …


The Association Between Stigma And Violence Among Individuals With Schizophrenia, Christopher Law Sep 2021

The Association Between Stigma And Violence Among Individuals With Schizophrenia, Christopher Law

Loma Linda University Electronic Theses, Dissertations & Projects

Schizophrenia is a psychotic disorder characterized by positive, negative, and cognitive symptoms. Individuals with schizophrenia (IWS) are often stigmatized and portrayed as dangerous. While the majority of IWS are not dangerous or violent, this image of the dangerous IWS is still pervasive across different cultures. Apart from the individuals who have exhibited antisocial traits prior to the onset of their psychosis, medication can significantly reduce the risk for aggressive and violent behaviors among IWS. However, as the literature reveals, medication noncompliance has become an significant issue among IWS. Studies show that stigmatization of schizophrenia has significantly contributed to individuals not …


Inflammation In Older Adults: Stress, Depression, And Aces, Kerianne Kramer Sep 2021

Inflammation In Older Adults: Stress, Depression, And Aces, Kerianne Kramer

Loma Linda University Electronic Theses, Dissertations & Projects

Studies conducted on Adverse Childhood Experiences (ACEs) have shown that childhood adversity is relatively common, likely to co-occur, and have dose-dependent relationships with mental and physical health in adulthood. People with a history of ACEs are likely to experience dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis, leading to increased inflammation production, greater stress reactivity, and decreased serotonin production. This longitudinal study explored the role depression and perceived stress have in the relationship between ACEs and inflammation while controlling for demographic characteristics (e.g., age, gender, ethnicity, education, difficulty meeting expenses). The study sample included 288 (61% female, 66% white, Mage = 68, …

Correlates Of Problematic Gambling As Correlates Of Problematic Video Game Use, Hyo Jin Lee

Loma Linda University Electronic Theses, Dissertations & Projects

Problematic video game use (PVGU), or addiction-like use of video games, affects a significant portion of the population and is associated with various negative physical and mental health problems. Given existing research regarding PVGU and gambling disorder, as well as the recent convergence of gambling and video gaming activities, studying correlates of gambling disorder in the context of PVGU may help identify novel correlates of PVGU that can be used to improve assessment and intervention. The aim of the current study was to examine correlates of gambling disorder, such as gaming fallacies and perceived locus of control, as potential predictors …


Body Dissatisfaction, Verbal Commentary, Social Influences And Cigarette Smoking, Nicole Bennett Sep 2021

Body Dissatisfaction, Verbal Commentary, Social Influences And Cigarette Smoking, Nicole Bennett

Loma Linda University Electronic Theses, Dissertations & Projects

In the United States, about a quarter of adolescent girls report clinical levels of body dissatisfaction, and approximately 15% of adults smoke cigarettes. Body dissatisfaction can predict the development of an eating disorder, and smoking is linked with dozens of diseases, both of which can lead to premature death. The current study tested body dissatisfaction as a mediator of the relationship between frequency of positive verbal commentary and smoking, and the relationship between sociocultural influences (perceived family, peer, media, and significant other pressures) and smoking, while controlling for body mass index. Participants included 397 female undergraduates (Mean age = 20.32) …


A Review Of Malingering Measures In Psychology, Dylan Faire Sep 2021

A Review Of Malingering Measures In Psychology, Dylan Faire

Loma Linda University Electronic Theses, Dissertations & Projects

Malingering describes the act of feigning physical or psychological symptoms for external gain, which may include exaggerating symptoms on psychological testing. Thus, standardized measures are needed to detect malingering and invalid responses for accurate interpretation of test results. This review examines existing literature on the most well-known cognitive and psychiatric malingering measures. Optimal contexts, in terms of population and setting, for each measure are examined, and directions for future research and recommendations discussed.


The Effects And Mechanisms Of Phytochemicals On Alzheimer’S Disease Neuropathology, David Ross Sep 2021

The Effects And Mechanisms Of Phytochemicals On Alzheimer’S Disease Neuropathology, David Ross

Loma Linda University Electronic Theses, Dissertations & Projects

Alzheimer’s disease effects millions of people, yet pharmacological treatments are limited. In the absence of effective treatments, identifying factors that can decrease the risk of developing Alzheimer’s disease is of significant interest. A growing body of epidemiological and experimental evidence suggests that dietary fruits and vegetables can have neuroprotective effects against the harmful effects of oxidative stress, neuroinflammation, and aging. These effects are mediated by various phytochemicals, which are compounds found in plants that can possess antioxidant, anti-inflammatory, and other beneficial properties. This review addresses epidemiological and experimental evidence for the effects and potential mechanisms of several commonly consumed phytochemicals …


Predictors Of Aggression Among Adolescent Girls, Sarah Joy Park Aug 2021

Predictors Of Aggression Among Adolescent Girls, Sarah Joy Park

Loma Linda University Electronic Theses, Dissertations & Projects

Women and girls will often deny what they feel and think to maintain their relationships. Silencing the self can be detrimental to the physical and mental health of teenage girls. This stifling of the self is related to depression, earlier first intercourse, eating disorders, and less relationship satisfaction. Girls who silence their voices are also likely to have difficulty expressing themselves when they feel angry. In this study we explored the relationship between silencing the self and physical, verbal, and indirect aggression. Our sample consisted of 88 teenage girls from two high schools, with a mean age of 16. They …


Symptoms, Executive Function, Mentalization, And Functional Capacity In Schizophrenia, Yasmine Kolahi Aug 2021

Symptoms, Executive Function, Mentalization, And Functional Capacity In Schizophrenia, Yasmine Kolahi

Loma Linda University Electronic Theses, Dissertations & Projects

One of the core features in schizophrenia is a deficit in real-world functioning as expressed through difficulties in the ability to work, engage in social relationships, attend to self-care, and participate in recreational and community activities. Due to this impact on overall quality of life, experts have investigated possible links between the observable symptoms of the illness, such as negative symptoms, with functional outcomes. Ample research has shown that neurocognition is one possible candidate, although fewer studies have explored the specific contributions of executive functioning, or the cognitive process associated with top-down regulation of cognition and behavior. The links between …


Factors Related To Cognitive Reserve In Healthy Older Adults, Ann Tram Nguyen Aug 2021

Factors Related To Cognitive Reserve In Healthy Older Adults, Ann Tram Nguyen

Loma Linda University Electronic Theses, Dissertations & Projects

Background. Physical and cognitive impairments are two of the most prevalent age-related conditions, with evidence that both factors interact prior to or concurrently with the earliest detectable stages of cognitive impairment. Cognitive reserve (CR) allows an individual to cope more successfully with age-related brain and functional changes and is associated with better cognitive function and reduced risk of cognitive decline. However, it remains unclear to date the specific roles of individual markers of CR, and whether or not this relationship is modified by genetic risk (ApoE-4 genotype) and/or physical function. Method. We assessed cognitive functioning (global cognition, psychomotor …


Therapists’ Willingness To Access Client Social Media Accounts In The Context Of Suicide Risk, Jacob A. Vermeersch Jun 2021

Therapists’ Willingness To Access Client Social Media Accounts In The Context Of Suicide Risk, Jacob A. Vermeersch

Loma Linda University Electronic Theses, Dissertations & Projects

The past two decades has seen a proliferation of social media use, leading to a growing body of research on the potential utility for clinical contexts. In the current study, we examine willingness of psychologists to utilize client social media to inform suicide risk-assessment and risk-related treatment decisions, and the ethical principles they used to guide their considerations. Participants were asked of the likelihood they would engage in 1) a social media-informed risk assessment, where the therapist uses client social media to inform their initial determination of risk level, and 2) a digital welfare check, where the therapist accesses an …

Electrophysiological Measures Of Context Updating Along The Schizophrenia Spectrum, Rachel J. Mcclure

Loma Linda University Electronic Theses, Dissertations & Projects

Objective: Schizotypy is conceptualized on the spectrum of schizophrenia spectrum, but is seldom studied with schizophrenia. We investigated whether individuals endorsing schizotypy traits exhibit P300 amplitude and power more similar to deficits in those with schizophrenia or more similar to healthy controls. Method: Participants consisted of 109 individuals, 63 females, ages 18 to 64, (M = 30.98 years, SD = 9.9 years). P300 was elicited with an auditory oddball task, and peak amplitude & latency as well as power within the peak window within the delta, theta, alpha, beta & gamma frequencies were calculated. Schizophrenia symptom severity was measured using …


Anxiety In Preschool-Aged Children With Autism: Rates, Symptoms, And Predictors, Neilson Chan Apr 2021

Anxiety In Preschool-Aged Children With Autism: Rates, Symptoms, And Predictors, Neilson Chan

Loma Linda University Electronic Theses, Dissertations & Projects

Epidemiological studies indicate that children with Autism Spectrum Disorder (ASD) are at high risk for developing co-occurring anxiety symptoms and diagnosable anxiety disorders, with prevalence rates ranging from 40% to 78%. Further, studies have suggested that children with ASD experience more clinically significant symptoms of anxiety compared to children without ASD as early as toddlerhood. However, few studies have examined the comorbidity of anxiety and ASD in early childhood. In the current study, we included a sample of young children (ages 3 to 5) with ASD (n = 77) and an age-matched typically developing comparison group (n = 55) to …


Wisdom Program As A Treatment For Geriatric Psychopathology, Darrell Gene Rice Mar 2021

Wisdom Program As A Treatment For Geriatric Psychopathology, Darrell Gene Rice

Loma Linda University Electronic Theses, Dissertations & Projects

As the population of older adults continues to rise, the prevalence and incidence of psychopathology in this group will increase as well. The most common psychopathologies observed in older adults include depression, anxiety, and mild cognitive impairment. These conditions are often co-occurring; however, few interventions are designed to simultaneously address all three. We examined whether the LLU WISDOM adult partial outpatient program was effective in reducing depression and anxiety, as well as improving cognitive function in a sample of older adults. We hypothesized that compared to a control group receiving usual clinical care, participants in the WISDOM program will demonstrate …


Subjective Emotional Experience And Social Cognition In Schizophrenia And Healthy Controls, Shaina R. Ponce Dec 2020

Subjective Emotional Experience And Social Cognition In Schizophrenia And Healthy Controls, Shaina R. Ponce

Loma Linda University Electronic Theses, Dissertations & Projects

Individuals with schizophrenia have impaired social cognitive abilities that include emotion recognition, Theory of Mind and affective empathy deficits compared to healthy controls (Bekhtereva, Craddock, & Müller, 2015; Bora, Gökçen, & Veznedaroglu, 2008; Bora, Yucel, & Pantelis, 2009; Martin J Herrmann, Ellgring, & Fallgatter, 2004). Subjective emotional experience measured by valance (pleasantness) and arousal have been found to have significant effects on perceptual processes related to emotion recognition (Champion, 2016; Lang, Greenwald, Bradley, & Hamm, 1993; Lundqvist, Juth, & Öhman, 2014). It is not clear to what extent valance and arousal impact emotion recognition, Theory of Mind, and empathy in …


Chronic Disease And Its Relationship With Elder Mistreatment, Ryan Wong Oct 2020

Chronic Disease And Its Relationship With Elder Mistreatment, Ryan Wong

Loma Linda University Electronic Theses, Dissertations & Projects

The relationship between chronic disease and elder mistreatment was investigated using a meta-analytic approach, where 48 studies were utilized for the random effects analysis of 178 effect size data. Twelve risk markers were combined into four categories: endocrine disease, heart disease, neurological disease, and other chronic diseases for comparative analysis of elder mistreatment. Neurological disease (OR = 1.51) was found to have a significantly stronger association with elder mistreatment when compared to the heart disease category (OR = 1.17) and the other chronic disease category (OR = 1.26). When specifically investigating emotional abuse, there was a significantly stronger association with …


Religion And Risky Sex In A Sample Of Predominately Black Young Adult Men, Jade Seto Oct 2020

Religion And Risky Sex In A Sample Of Predominately Black Young Adult Men, Jade Seto

Loma Linda University Electronic Theses, Dissertations & Projects

This study examined religion and spirituality as protective factors against risky sexual behaviors among young adult Black and non-Black men while exploring the mediating mechanisms. Participants included 110 young adult men (58.2% Black; 41.8% non-Black). Results revealed that intrinsic religiosity predicted a moderate decrease in total sexual risk-taking, while sexual permissiveness predicted a moderate-large increase. Race/ethnicity was not a significant independent predictor. Furthermore, intrinsic religiosity significantly predicted decreased sexual risk-taking through the indirect effect of sexual permissive attitudes; suggesting religiosity served as a buffer against sexual risk behaviors. Implications are suggested for professionals in educational and clinical setting


The Relationship Between Cannabis Experience, Schizotypy, And Psychosis, Kimberly Alexandra Igirio Oct 2020

The Relationship Between Cannabis Experience, Schizotypy, And Psychosis, Kimberly Alexandra Igirio

Loma Linda University Electronic Theses, Dissertations & Projects

A number of genetic and environmental vulnerabilities precipitate the clinical expression of schizophrenia and related psychotic disorders. Schizotypy and cannabis use are identified risk factors for the development of these disorders (Vaucher et al., 2018; Debanné et al., 2015). Schizotypy is defined as a set of personality characteristics and experiences that fall along the schizophrenia spectrum (Debbané et al., 2015). Individuals with schizotypy exhibit traits that are similar to, but less severe than, those of psychosis including marked differences in characteristic patterns of thinking, feeling, and behaving (Esterberg, 2010). An increase in severity of symptoms also correlates to impairment in …

Adverse Childhood Experiences (ACEs) include physical, sexual, or psychological maltreatment, domestic violence, household mental illness, household substance abuse and incarceration of parents. ACEs may have negative impacts on children, including brain development and health outcomes. Parents are pivotal figures in children’s lives that contribute significantly to their health, and cognitive development, and may be a critical protective factor, contributing to children’s resiliency and healthy growth. This study focused on the intellectual development of 5-11 year-old children whom may have been exposed to ACEs in their homes. More specifically, the purpose of this study was to examine parental involvement as a …


The Effects Of A Polyphenol-Rich Diet In A Fruit-Fly Model Of Traumatic Brain Injury, Alexandra D. Trofimova Sep 2020

The Effects Of A Polyphenol-Rich Diet In A Fruit-Fly Model Of Traumatic Brain Injury, Alexandra D. Trofimova

Loma Linda University Electronic Theses, Dissertations & Projects

Traumatic brain injury (TBI) is a leading cause of death in the United States. Inflammation and oxidative stress activated by the TBI can lead to systemic inflammation. Gastrointestinal complications are common secondary injuries to TBI and are associated with elevated levels of common pro-inflammatory cytokines and oxidative stress found across the body. Intestinal permeability after TBI has also been established in the fruit fly, Drosophila melanogaster. Pomegranate polyphenols have strong anti-inflammatory properties that may reduce brain and intestinal inflammation and improve functioning after TBI. This study examined the protective effects of pomegranate polyphenol supplementation in a Drosophila model of TBI. …
