To What Extent Do Different Types And Dosages Of Cannabinoids Have In Treating Anxiety Disorder, Lourdes Cristina Garcia Carrillo

Doctoral Dissertations and Projects

This mixed-methods study investigated the efficacy of various cannabinoid types and dosages in treating anxiety disorders among young adults (19–23), examining cannabis's role in regulating a deregulated endocannabinoid system. Fourteen participants tracked real-time anxiety symptoms, strain type, dosage, and affective states using the Releaf App. Quantitative analyses included repeated-measures ANOVA and Pearson correlation, complemented by quantitative content analysis of affect descriptors. Key findings revealed a statistically significant reduction in self-reported anxiety symptoms following cannabis use (p < .001, partial 2 = .97), supporting the hypothesis that cannabis can regulate a deregulated endocannabinoid system. No significant differences in anxiolytic effects were observed among Indica, Hybrid Indica/Sativa, and Hybrid Sativa/Indica strains. The optimal dosage for perceived anxiety relief appeared to be higher than initially hypothesized, with a moderate-to-strong association between dosage and anxiety relief (r = .662, p = .0099). Participants overwhelmingly reported positive affective states, such as "calm," "peaceful," and "relaxed," post-cannabis use, with no negative descriptors observed in the analyzed data. These results suggest that cannabis can serve as a short-term coping strategy for anxiety in young adults, leading to perceived emotional regulation.

Values And The Black-White Mental Health Paradox, Tiffany Soignoli

Doctoral Dissertations and Projects

This quantitative cross-sectional study explored the Black-White mental health paradox (BWMHP), which proposes that Black individuals have better or similar mental health than White individuals despite additional stressors, but the etiology of these differences has not been found. While self-esteem has been consistently found to differentiate Black and White adults in relation to the BWMHP, values have not been investigated. Therefore, using a total sample of 191 Black and 191 White American adults (N = 382), values were examined to determine whether they contribute to the differences in depression, stress, and anxiety, leading to better mental health. Chi-square tests of …

Using bivariate correlations and regression analyses, the results revealed significant correlations among constructs, but the predictive power …

The Relationship Between Employee Perception Of Perfectionistic Leadership And Employee Outcomes, Jennifer Parras

Doctoral Dissertations and Projects

Research shows perfectionism to be a multidimensional trait, yielding both positive and negative results. Given its evolving nature and impact, perfectionism is becoming more widely researched and an important trait to study. Multidimensional perfectionism, in its positive side, refers to striving towards excellence, whereas in its negatives side refers to a concern of failure. Today, multidimensional perfectionism research focuses more on the individual and interpersonal consequences of the trait with less focus on the workplace consequences of performance. Therefore, the aim of this study was to investigate the relationship between the dyadic relationship of leader’s perfectionism and employee outcomes. This …

Helicopter Parenting And Its Impact On The Well-Being Of Diverse Emerging Adults, Tamieka S. Martin

Doctoral Dissertations and Projects

Helicopter parenting involves excessive over-involvement, overprotection, and autonomy restriction. Research suggests that helicopter parenting often leads to poor outcomes for emerging adults (18-25). This style of parenting is incongruent with the appropriate developmental stage of emerging adulthood, which prioritizes autonomy supportive parenting for more positive well-being outcomes. Literature on this phenomenon consists of a majority White female sample. This study is an examination of the relationship between well-being outcomes (depression, anxiety, and autonomy) for a diverse population of emerging adults who were helicopter parented. This correlational quantitative study includes 120 college participants. Spearman’s rho correlation was employed to analyze the …

The Role Of Faith In Coping With Mental Health Challenges In Late Life: A Phenomenological Study Of Religious Experience In The Aging Population, Krista Kelley

Doctoral Dissertations and Projects

Depression, anxiety, and suicidal ideation are significant concerns among older adults. These conditions are often neglected due to stigma, atypical symptom presentation, and medical comorbidities, resulting in increased healthcare utilization, heightened suicide risk, and emotional dysregulation. Psychosocially, these challenges obstruct a successful resolution of Erikson’s final stage, ego integrity versus despair, leading to dissatisfaction, regret, and reduced well-being. Although previous research has suggested a link between religious engagement and improved mental health outcomes, few studies have explored older adults’ lived experiences of faith in coping with mental health. This qualitative phenomenological study examined the experiences of 25 older adults regarding …

Spiritual Fortitude And Foster Care, Alesha R. Leonard

Doctoral Dissertations and Projects

In 2022, over 200,000 American children exited foster care settings, with many reporting feeling underprepared to face the demands of adulthood (Children’s Bureau, 2023; Haggman-Laitila et al., 2018). Adults with foster care backgrounds are more prone to struggle with cognitive, emotional, and behavioral development, which may hinder brain development throughout emerging adulthood years (Avery & Freundlich, 2009). This study introduced spiritual fortitude as a potential protective factor against poor transitions to adulthood and against mental health struggles among adults with foster care backgrounds. Spiritual fortitude involves development and practice of spiritual coping mechanisms to build resilience (Van Tongeren et al., …
