TITLE: Gender differences in substance use and depression among caregivers AUTHOR INFO Memunat Ogunmefun Manik Ahuja Author Affiliations: College of Public Health, East Tennessee State University, Johnson City, TN 37614, United States Background: Around 20% of adults in the United States provide care for a loved one, with approximately 61% of these caregivers identifying as women. Typically, a caregiver is defined as someone who provides help and support to a family member or friend who is facing illness or disability as a result of a medical condition. Caregiving may be rewarding, but it can also cause significant psychological strain, leading to adverse consequences, such as turning to substance use to cope with stress. Increased levels of stress in caregivers can make them more susceptible to various health problems, such as depression and anxiety disorders, sleep disturbances, compromised physical health, cardiovascular disease, and substance use disorders. The aim of this study is to examine the gender differences in substance use and depression among caregivers using a nationally representative sample. Methods: We used cross-sectional data from the 2021 Behavioral Risk Factor Surveillance System a nationally representative U.S. telephone-based survey of adults aged 18 years and extracted data for non-metropolitan/rural counties. Logistic regression analyses were conducted separately to test the association between self-identified caregiver status and three outcomes, including depression and current alcohol use. We controlled for past month’s income, race, educational status, and age. Caregiver status was identified based on providing care or assistance to a friend or family member over the last 30 days. Results: Overall, 21.7% (n=13,653) of our participants self-identified as a caregiver, while 19.5% reported depression, past month alcohol use (48.2%), past month smoking (13.5%), and past month marijuana use (4.2%). Significant interactions were found between caregiver status and gender (p=.0001). We then stratified by gender. Among males, self-identified caregiver status was associated with higher odds of depression (OR=1.48, 95% CI, 1.41,1.55). Among females, caregiver status was associated with higher odds of depression (OR=1.48, 95% CI, 1.29, 1.39). Caregiver status did not predict alcohol use. Conclusion: Caregiving has been known to cause psychological strain which may be associated with alcohol use and depression. According to this study, being a caregiver may contribute to depression regardless of gender, but it does not necessarily affect alcohol consumption. The gender differences observed in this study highlight the need for interventions and support programs that are tailored to meet the unique needs and challenges faced by male and female caregivers. It is important for healthcare professionals to consider caregiver status and gender when assessing mental health risk factors.

Posttraumatic stress disorder (PTSD) and substance use disorder (SUD) frequently co-occur. Comorbid PTSD+SUD confers heightened risk of other mental health concerns, suicidality, mortality, and functional impairment. Current treatments for comorbid PTSD+SUD show inconsistent results, highlighting the need for a more comprehensive understanding of the associations between PTSD and SUD symptoms. The current dissertation aimed to characterize the associations between PTSD and SUD using structural equation modelling among three different samples with differing clinical severity and presentation: (1) concurrent disorders sample with a high prevalence of PTSD; (2) an in-patient sample seeking treatment for PTSD; and (3) a subclinical sample of healthcare workers and public safety personnel. Data were extracted from multiple clinical databases across different studies to evaluate the associations between PTSD symptoms and alcohol/cannabis/substance use-related problems. Furthermore, the role of underlying mechanisms such as dissociation and emotion dysregulation, which are associated with both PTSD and SUD, were analyzed. All analyses used a structural equation modelling framework to represent the complex clinical presentation of comorbid PTSD+SUD analytically. A relatively consistent pattern of results was observed across the three samples. Global PTSD symptoms were significantly associated with cannabis-related problems, alcohol-related problems, and other illicit substance-related problems. Among PTSD symptoms, the reactivity symptom cluster (characterized by symptoms of hypervigilance, irritability, reckless behaviour, problems with concentration and sleep disturbances) was significantly associated with alcohol/cannabis/substance-related v problems across among the three samples. Furthermore, underlying mechanisms such as dissociation and emotion dysregulation significantly mediated the relations between PTSD symptoms and alcohol/cannabis/substance-related problems. Overall, the current results contribute to the limited literature examining the associations between PTSD and SUD symptoms. Lastly, the current results have important clinical implications for identifying efficacious treatment targets for comorbid PTSD+SUD. / Dissertation / Doctor of Philosophy (PhD) / Psychological distress following a traumatic event, known as traumatic stress, is often associated with problematic alcohol and/or substance use. The co-occurrence of these two confers a heightened risk of other mental health problems. As such, studying how these phenomena are associated with one another and what about each thing is more important to the association is important to understand. The purpose was to examine the connection between these phenomena among three different groups of people: two treatment-seeking groups and non-treatment seeking group one group. Traumatic stress was associated with problematic substance use in all three groups. In addition, other factors like mentally escaping from your body and having difficulties with regulating your emotions explained how traumatic stress and problematic substance use were connected to each other. These findings can help clinicians hone their treatment programs to better help individuals struggling with traumatic stress and problematic substance use.

The present study examined characteristics and factors related to nonprescription use of stimulant medications in college-aged populations. Prior researchers have shown that students do not perceive that taking these medications is illegal or that the medications have negative effects (DeSantis & Hane, 2010; Rabiner et al., 2009). Therefore, we examined the perceptions of legal and health risks that are associated with consumption of stimulant medication along with motivations for use and other perceptions of use. The psychology research pool was used to recruit 995 undergraduate students to the survey. Data analysis showed that the combination of sharing and selling is the most commonly endorsed method of diversion for prescription stimulant medications. Analyses also showed that those involved in using nonprescription stimulants perceived lower legal and health risks compared to those uninvolved. Future research should continue to explore diversion behaviors and risks and benefits between users and non-users.

Daily temperature variations across an area can often be attributed to differences in land use/land cover (LULC). This study focuses on the relationships between the diurnal temperature ranges (DTRs) of 145 weather stations, classified as urban, agriculture, evergreen forests, deciduous forests, pine forests, and mixed forests. Paired samples t-tests were employed to test for significant DTR differences due to LULC type, season, and air mass type. Conflicting with previous research, agricultural areas reported the lowest DTRs, which may be due to the vegetation or to other physiographic variables. The forest types showed very few significant DTR differences. All of the LULC types experienced an annual bimodal DTR pattern, with peaks in April and October. Results of this study show that air mass has the largest influence on DTR (over LULC and season), therefore, the annual variability of air mass occurrence is most likely cause of the bimodal pattern.
