Cbd's Impact On Learning, Memory, And Anxiety: A Dose Response, Audrey Camacho

Psychology ETDs

Cannabidiol (CBD) is widely utilized for its therapeutic properties, yet its impact on an unmanipulated model at baseline behavior remains poorly understood. This study investigates CBD’s dose-dependent behavioral profile on spatial learning, memory, and anxiety using Long-Evans rats. Subjects received a vehicle, 20 mg/kg, or 40 mg/kg CBD dose prior to assessment in the Morris Water Task (MWT) and Elevated Plus Maze (EPM). MWT results indicated consistent Day 1 learning, but the 40 mg/kg dose induced a temporary disruption 24 hours post-treatment. Performance returned to baseline by day 6. On the EPM, traditional anxiety markers remained unchanged. While CBD did …

Development And Validation Of The Ipip-Ocean: A Hierarchical Facet-Level Measure Of The Big Five, Caleb Niccum

Graduate Theses/Dissertations

This study focused on developing a mid-range, hierarchical, five-factor, 20-facet personality inventory (the IPIP-OCEAN) composed of 100 items drawn from both the IPIP-NEO-300 and the Abridged Big Five Circumplex. Hierarchical confirmatory factor analysis was used to validate the factor structure. Depression and anxiety, measured with the PHQ-9 and GAD-7, were used to further validate the measure through discriminant and convergent validity by examining whether the domains and facets of the IPIP-OCEAN produced findings consistent with those reported for similar scales in prior depression and anxiety research. Numerous factor analyses were conducted on the IPIP-OCEAN dataset (N = 1,058), and a …

Anxiety And Adaptive Functioning In Young Adults: The Moderating Role Of Psychological Flexibility, Makenzie L. Kennedy, Jeffrey E. Cassisi

Honors Undergraduate Theses

Anxiety is highly prevalent among emerging adults and is associated with impairments in academic, social, and daily functioning. While previous research has documented strong associations between anxiety and adaptive functioning, the present study uniquely tested psychological flexibility as a potential moderator that may foster resilience and adaptive coping.

Undergraduate students (N = 522) from the University of Central Florida completed measures of anxiety (PROMIS-A, GAD-7, STAI-S), adaptive functioning (WHODAS 2.0), and psychological flexibility (COMPACT-23). Confirmatory factor analyses supported distinct but correlated latent constructs of anxiety and adaptive functioning. Due to poor subscale intercorrelations, the COMPACT-23 total score was modeled as …

Method

A cross-sectional online survey was completed by 406 international pilots, who reported their duty rosters of the last two months. Pilots also self-assessed their stress-levels, sleep problems, fatigue, wellbeing, and mental health.

Results

Although pilots …

Factors That Affect Anxiety And Acculturation In Syrian Emigrants, Thomas H. Anderson

Walden Dissertations and Doctoral Studies

Since the Syrian civil war began in 2011, more than 6 million Syrians have registered as refugees. Many displaced Syrians suffer myriad mental health disorders, including anxiety, which become a burden as they attempt to acculturate into a foreign culture. Research to understand the Syrian refugees has been conducted since the conflict began; however, the findings are inconsistent. Existing academic research does not adequately capture the depth of anxiety of Syrian emigrants, nor does it present an accurate picture of the challenges of acculturation. The purpose of this quantitative study was to examine the differences in anxiety and acculturation based …

Understanding Motivations To Attend Various Sized Churches: A Study Using Family Communication Patterns, Expectancy Violations, And Anxiety To Predict Church Attendance, Molly Bradshaw

Masters Theses, 2020-current

Two separate studies were conducted to examine whether communication variables impact religious views and church attendance. For the first study, 228 students from a large Southeastern university completed a web survey. The second study was a web survey of 204 adults that was conducted via Amazon Mechanical Turk (MTURK). Both surveys were sent out to determine one’s motivations to attend a small, medium, or large church using family communication, anxiety, expectations, and religion variables as predictors. Family communication, anxiety, and expectancy variables were positively correlated to many aspects of religious views. Hierarchical regression models utilizing demographics, family communication, anxiety, expectancy …

The ultimate purpose of this study is to provide insight and education to mental health clinicians, politicians and the general public of the numerous effects poverty has on mental health, in addition to the most beneficial ways to combat those insidious effects. The specific barriers met by individuals of low socioeconomic status severely affect psychological and physical health, as well as social and environmental relationships, which therefore diminish overall quality of life. The aim of this study is to examine the effectiveness of implementing a collaborative mental health approach for low income individuals on length of engagement in services and …

The Effects Of Oral Contraceptives On Mood And Affect: A Meta-Analysis, Erica M. Motter

Cal Poly Humboldt theses and projects

Combined oral contraceptive (COC) pills are widely used by women of reproductive age, but there is still little conclusive evidence that exists about the mood-related side effects associated with their use. This meta-analysis examined the relationship between oral contraceptive use and mood effects such as depression and anxiety to determine what role, if any, that COCs may have in the worsening or improvement of women’s mood when taking them. Effect sizes compared the differences in women’s mood scores before taking COCs and after one or more cycles of use. Seventeen studies made up of 25 individual samples contributed 71 effect …

The Impacts Of Religious Discrimination Towards Anxiety In Diverse Populations, Sharlaine Marie Ortiz-Diaz

Walden Dissertations and Doctoral Studies

Previous research has indicated that outcomes of depression, anxiety, and suicidal ideation could stem from religious discrimination (RLGD). However, there remains an important gap in the current literature regarding RLGD impacts with non-Muslim populations. Further, the moderating effects of sex, race, and national origin (moderating variables [MVs]) have yielded mixed findings concerning anxiety (dependent variable). The intergroup anxiety theory and the integrated threat theory elaborate on perceived threats and potential anxiety of intergroup dynamics. The purpose of this quantitative study was to examine the role of religious preferences (independent variable), the MVs, and the RLGD-anxiety relationship. The sample consisted of …

Assessment Of Neurotensin Receptor Agonist Effects On Fear-Potentiated Startle, Mark Aaron Vanden Avond

All NMU Master's Theses

Systemic administration of the NTS₁ receptor agonist PD149163 has exhibited anxiolytic effects in male rats. The present study sought to further evaluate the potential anxiolytic effects of PD149163 by assessing this compound in both male and female C57BL/J6 mice using the fear-potentiated startle (FPS) paradigm. Startle chambers were equipped with a shock-grid floor, fluorescent light, and an acoustic startle speaker. Conditioning took place between the light and floor shock, and test sessions measured startle to a 90 dB noise burst while the light was on (FPS) or off. Startle magnitude did not differ between the male and female mice. …

The Effects Of Mindfulness On Affect And Substance Use, Alicia D. Carter

Honors College Theses

Previous studies have explored the impact of mindfulness on Big 5 personality traits, personality disorders, suicidal ideation, and alcohol use; additionally, mindfulness-based interventions (MBIs) have been used to treat individuals suffering from depression and anxiety. However, the practical application of mindfulness has been complicated by contradictory findings in the literature and inconsistent conceptualizations of the construct. The current study sought to investigate potential relationships between types of mindfulness, facets of mindfulness, substance use, and affect. Participants completed a battery of questionnaires related to mindfulness, correlates of neuroticism (i.e., depression, anxiety, and subjective happiness), and drinking-related consequences. Correlational analyses revealed significant …

The Effectiveness Of A Computer-Assisted, Cognitive-Behavior Program For Treating Anxiety Symptoms In Children With Autism Spectrum Disorder, Jennifer A. Zabel

PCOM Psychology Dissertations

Autism Spectrum Disorder (ASD) is a complex and multifaceted, neurodevelopmental disorder that severely impacts children and families across a variety of settings. Prevalence rates of ASD are continuing to increase rapidly, with sizeable intervention and treatment costs placed on families and society. Further complicating the matter, many individuals with ASD also evidence co-occurring anxiety symptoms or disorders and tend to be at a higher risk for developing such problems when compared to other clinical populations or typically developing children. This study investigated the effectiveness of a computer-assisted CBT program, Camp Cope-A-Lot (CCAL), in regards to reducing anxiety symptoms in four …

Evaluation Of The Psychometric Properties Of Two Short Forms Of The Social Interaction Anxiety Scale And The Social Phobia Scale, Allura L. Le Blanc, Laura C. Bruce, Richard G. Heimberg, Debra A. Hope, Carlos Blanco, Franklin R. Schneier, Michael R. Liebowitz

Department of Psychology: Faculty Publications

The Social Interaction Anxiety Scale and Social Phobia Scale are widely used measures of social anxiety. Using data from individuals with social anxiety disorder (n = 435) and nonanxious controls (n = 86), we assessed the psychometric properties of two independently developed short forms of these scales. Indices of convergent and discriminant validity, diagnostic specificity, sensitivity to treatment, and readability were examined. Comparisons of the two sets of short forms to each other and the original long forms were conducted. Both sets of scales demonstrated adequate internal consistency in the patient sample, showed expected patterns of correlation with measures of …
