OBJECTIVE: An alcohol-drinking culture exists among first-time-in-college students, where many of these students come to their university relatively inexperienced with alcohol, which may increase alcohol-related consequences. Several interventions exist to combat this campus problem. The current study investigates the use of a Deviance Regulation Theory (DRT) intervention, presented in a web-based manner, to increase alcohol Protective Behavioral Strategies (PBS), such as monitoring drinks,...
Show moreOBJECTIVE: An alcohol-drinking culture exists among first-time-in-college students, where many of these students come to their university relatively inexperienced with alcohol, which may increase alcohol-related consequences. Several interventions exist to combat this campus problem. The current study investigates the use of a Deviance Regulation Theory (DRT) intervention, presented in a web-based manner, to increase alcohol Protective Behavioral Strategies (PBS), such as monitoring drinks, using a designated driver, and drinking water in between alcoholic beverages, among college freshmen. METHOD: College freshmen participants (N = 157) completed web-based surveys examining alcohol behaviors once a week for six weeks. Participants were randomly assigned to one of three conditions: a positive frame about individuals who used PBS, a negative frame about individuals who did not use PBS, or a control group that did not receive a DRT intervention. Participants also reported their perception of PBS use among UCF students and friend. Data was analyzed in each PBS subtype: Manner of Drinking, Stop/Limiting Drinking, and Serious Harm Reduction. RESULTS AND CONCLUSION: Results indicate a negatively framed message with high perceived norm levels results in increased PBS use, which may suggest college freshmen have a strong drive to "fit in", or avoid standing out in negative ways. Further, there seems to be little desire to standout in positive ways among first-year students. This may be indicative of individuals who modify their behavior in order to assimilate to a new and unfamiliar environment. Furthermore, some PBS strategies were associated with decreases in alcohol consumption and alcohol-related problems. Results suggest a DRT intervention may be beneficial to first-time-in-college students.

Several interventions are currently used to encourage students to drink wisely with the goal of decreasing this problem drinking and the consequences of these behaviors. The current study analyzes the intention to use Protective Behavior Strategies through the model suggested in the Theory of Planned Behavior (TPB). METHOD: College student participants (N = 171) completed a web-based survey examining alcohol-related behaviors, intentions, and perceptions at the time of the survey and over the next four weeks. RESULTS AND CONCLUSION: At step 1, PBS intentions was regressed onto age and gender. This accounted for a small amount of variance in intentions. Next, the TPB predictors were added to the model which resulted in a significant improvement in the overall model fit. In the final model, perceived control over PBS use and peer PBS use norms were significant positive predictors of PBS use intentions. Attitudes toward PBS did not predict PBS use intentions.

Objective: Theoretical models that have guided the study of later-life depression include the vascular depression hypothesis, depression-executive dysfunction syndrome, and the CaR-FA-X model. Evidence suggests these can be integrated into a single developmental model of disordered mood (and its associated overgeneral memory feature) in later-life to delineate a mechanism of the vascular depression effect and identify modifiable intervention targets.Methods: In older adults, four serial...
Show moreObjective: Theoretical models that have guided the study of later-life depression include the vascular depression hypothesis, depression-executive dysfunction syndrome, and the CaR-FA-X model. Evidence suggests these can be integrated into a single developmental model of disordered mood (and its associated overgeneral memory feature) in later-life to delineate a mechanism of the vascular depression effect and identify modifiable intervention targets.Methods: In older adults, four serial mediation models evaluated the relationships between (1) vascular burden and depressive symptoms via executive control and rumination, and (2) vascular burden and autobiographical memory specificity (AMS) via executive control and rumination. In younger adults, four simple mediation models were conducted to compare results to older adults, including models assessing the relationships between (1) executive control and depressive symptoms via rumination, and (2) executive control and AMS via rumination. Bias-corrected bootstrapping was employed throughout.Results: Older adult n=56; younger adult n=63. Older adult serial mediation models demonstrated significant individual relationships between a working memory measure and depressive symptoms, as well as between rumination and depressive symptoms. The vascular depression effect neared significance. No other direct or indirect effects were supported. In younger adults, rumination was significantly associated with depressive symptoms; all other hypothesized relationships were not significant.Conclusions: Model 1, evaluating the impact of vascular burden on depressive symptoms in older adults via working memory and rumination, respectively, was the most effective in integrating vascular depression, DED, and CaR-FA-X. However, there was not support for a vascular depression mechanism. Null results in this sample could be attributable to inadequate power or measurement error. Clinically, results promote interventions that target older adults presenting with depression, executive dysfunction, or rumination, independently or combined.

OVERVIEW: Social anxiety disorder is the third most prevalent psychiatric disorder in the United States. Dissociation can arise during acute daily social stressors in individuals with social anxiety. This study examined the relationship between social anxiety and functional outcomes (i.e., alcohol-related consequences and relationship satisfaction) as moderated by levels of dissociation (i.e., depersonalization/derealization). It was hypothesized that dissociation would moderate the...
Show moreOVERVIEW: Social anxiety disorder is the third most prevalent psychiatric disorder in the United States. Dissociation can arise during acute daily social stressors in individuals with social anxiety. This study examined the relationship between social anxiety and functional outcomes (i.e., alcohol-related consequences and relationship satisfaction) as moderated by levels of dissociation (i.e., depersonalization/derealization). It was hypothesized that dissociation would moderate the relationships between social anxiety and alcohol-related consequences and between social anxiety and relationship satisfaction. METHOD: College students who endorsed alcohol use within the past 30 days (n = 320) and college students who reported having been in a romantic relationship lasting 30 or more days (n = 364) were recruited through the Psychology Department's Sona system. All participants completed measures of social anxiety, dissociation, alcohol use motives, alcohol-related consequences, and relationship satisfaction as part of an online questionnaire. RESULTS: Findings indicated no moderation effect in either model; both social anxiety and dissociation predicted alcohol-related consequences via coping-motivated alcohol use. Additionally, there was a negative association between dissociation and relationship satisfaction. CONCLUSIONS: Future research should include longitudinal research designs or ecological momentary assessment designs and should examine these relationships in clinical samples.

Show moreCaregivers are a diverse group of individuals with a variety of backgrounds and roles; however, research has widely overlooked young adults in this population. This study investigated young adult caregiver circumstance, burden, and use of support services with the purpose of improving future caregiving research and interventions. Study 1 compared burden and circumstance among young, middle aged, and older adult caregivers (N = 285) in addition to developmental indicators among young adults caregiver and demographically matched non-caregiver peers (n = 225). Study 2 surveyed caregivers from each age group (N = 151) on barriers to care, treatment preferences, and interest in services. Results from study 1 indicated that young adult caregivers adopted similar caregiving roles and factors linked to burden; however, they reported additional stressors such as higher rates of childcare and commuting to provide care. Compared to demographically matched-peers, young adult caregivers were more likely to work part-time and earn a substantially lower yearly income. Study 2 replicated original findings and revealed that young adult caregivers endorsed elevated attitudinal barriers to care and are the least likely age group to speak to physicians about caregiving. Overall, findings reveal the similarity in caregiving role that young adults take on, as well as several unique burden factors. Caregivers across age groups disclosed moderate treatment expectancy for support services, and all reported greater interest in online-based treatment. Young adult caregivers were more likely to take on responsibilities such as childrearing and employment, thus impacting their available time and financial support. However, these findings do not explain the overwhelming lack of young adult caregivers in research. Future studies should re-evaluate sampling methods and inclusion criteria, or explore more accessible means of intervention, such as web-based services.

Show moreAdverse sexual outcomes (e.g., sexual regret, sexual risk, and sexual assault) are a common experience among college students. In particular, regretted sex is reported by a third of college students and may result in psychological harm. Previous literature has found that alcohol is involved in approximately one third of regretted sex experienced by college students. A gap exists in the literature identifying who is more susceptible to experiencing a regretted sexual experience. Previous research has shown that students who implement protective behavioral strategies (PBS) while drinking are able to reduce alcohol-related negative consequences, including regretted sexual experiences. Three sub-types of PBS exist: Stopping/Limiting Drinking (SLD), Manner of Drinking (MD), and Serious Harm Reduction (SHR). The current study examines associations between regretted sexual experiences, alcohol use, and PBS. Participants were a sample of college students (n = 349) who completed a series of online surveys that assessed drinking habits, alcohol-related negative consequences (e.g., regretted sex), and PBS use. A multi-group path analysis (grouped by gender) found that alcohol use was positively associated with regretted sexual experiences. One of the three PBS sub-types, MD, was negatively associated with regretted sexual experiences. This association was mediated by alcohol use. A different PBS subtype, SHR, yielded a direct negative relationship with regretted sexual experiences for women, but not for men. Lastly, the interaction of SHR and alcohol use was significantly associated with regretted sexual experiences and varied by biological sex. Among women, low SHR potentiated the positive association between alcohol and regretted sex; in contrast, high SHR attenuated this association. In order to inform future interventions and subsequently decrease the number of alcohol-related negative consequences, further examination of differences in relationships between PBS subtypes, alcohol use, and regretted sex for men and women is warranted.

OVERVIEW: Psychopathy has been an area of growing interest in psychology for the last half century. Currently, the most common conceptualization of psychopathy breaks it down into two factors: primary and secondary psychopathy. More recently, psychopathy has been viewed through a more nuanced model, the Triarchic Model of Psychopathy. The present study examines the relationship between the three facets of the Triarchic Model and alcohol pathology via aspects of impulsivity and Protective...
Show moreOVERVIEW: Psychopathy has been an area of growing interest in psychology for the last half century. Currently, the most common conceptualization of psychopathy breaks it down into two factors: primary and secondary psychopathy. More recently, psychopathy has been viewed through a more nuanced model, the Triarchic Model of Psychopathy. The present study examines the relationship between the three facets of the Triarchic Model and alcohol pathology via aspects of impulsivity and Protective Behavioral Strategies (PBS). METHOD: A college student sample of n = 967 individuals who endorsed consuming alcohol completed surveys regarding the Triarchic Model, impulsivity, PBS use, and alcohol pathology. RESULTS: Our findings indicate that boldness and disinhibition are significant predictors of alcohol pathology. Boldness was partially mediated by conscientiousness, while disinhibition was partially mediated by both conscientiousness and PBS use. Meanness was not associated with higher levels of alcohol pathology. CONCLUSIONS: It seems that aspects of psychopathy related to disinhibition and boldness are predictive of alcohol pathology, while meanness, though similar to primary psychopathy, does not relate to alcohol pathology as hypothesized. This thesis not only adds to the literature between psychopathy and alcohol pathology but allows for a more exact insight regarding aspects of psychopathy and their relation to alcohol pathology.
