Physical Aggressiveness And Gray Matter Deficits In Ventromedial Prefrontal Cortex, David S. Chester, Donald R. Lynam, Richard Milich, C. Nathan Dewall

Psychology Faculty Publications

What causes individuals to hurt others? Since the famous case of Phineas Gage, lesions of the ventromedial prefrontal cortex (VMPFC) have been reliably linked to physically aggressive behavior. However, it is unclear whether naturally-occurring deficits in VMPFC, among normal individuals, might have widespread consequences for aggression. Using voxel based morphometry, we regressed gray matter density from the brains of 138 normal female and male adults onto their dispositional levels of physical aggression, verbal aggression, and sex, simultaneously. Physical, but not verbal, aggression was associated with reduced gray matter volume in the VMPFC and to a lesser extent, frontopolar cortex. Participants …

Examining The Protective Effect Of Ethnic Identity On Drug Attitudes And Use Among A Diverse Youth Population, Tamika C. B. Zapolski, Sycarah Fisher, Devin E. Banks, Devon J. Hensel, Jessica Barnes-Najor

Educational, School, and Counseling Psychology Faculty Publications

Ethnic identity is an important buffer against drug use among minority youth. However, limited work has examined pathways through which ethnic identity mitigates risk. School-aged youth (N = 34,708; 52 % female) of diverse backgrounds (i.e., African American (n = 5333), Asian (n = 392), Hispanic (n = 662), Multiracial (n = 2129), Native American (n = 474), and White (n = 25718) in grades 4–12 provided data on ethnic identity, drug attitudes, and drug use. After controlling for gender and grade, higher ethnic identity was associated with lower past month drug use …

Odd Symptom Network During Preschool, Tess E. Smith, Christine A. Lee, Michelle M. Martel, Marni E. Axelrad

Psychology Faculty Publications

Several different conceptualizations of Oppositional Defiant Disorder (ODD) symptoms have been proposed, including one undivided set of symptoms (DSM-IV-TR; APA 2000); two domains of symptoms subdivided into affective and behavioral; and three domains of symptoms subdivided as angry/irritable, argumentative/defiant, and spiteful. The current study utilizes a novel approach to examining the division of ODD symptoms through use of network analysis. Participants were 109 preschoolers (64 male) between the ages of three and six (M = 4.34 years, SD = 1.08) and their parents and teachers/caregivers, who provided ratings of ODD symptoms. Results are consistent with one-, two-, and three- …

Leaving "The Life:" Exploring Services For Women Exiting Prostitution, Katherine A. Cascio

Theses and Dissertations--Educational, School, and Counseling Psychology

Women in prostitution (WIP) are significantly more likely to experience mental health issues and trauma than the general population (Farley, 2003; Ling, Wong, Holroyd, & Gray, 2007; Rössler et al. 2010; Roxburgh, Degenhardt, & Copeland, 2008). Previous research addressing the mental health of WIP emphasizes treating trauma to help women exit, both trauma that predated entry into prostitution and trauma experienced during prostitution (Carter & Dalla, 2006; Farley, 2003). Very little research is available on services for WIP, leaving psychotherapists with limited guidance on providing effective mental health treatment. Although programs exist exclusively to assist women leaving prostitution, little is …

Examining Substance-Use Treatment Utilization Among Incarcerated Women In Central Appalachian Jails, Rae Lyn Glover

Theses and Dissertations--Educational, School, and Counseling Psychology

Women in Central Appalachia represent a significant proportion of those engaging in problematic patterns of opioid use, which is concerning given the limited available services in the region and gender specific treatment barriers. This investigation seeks to understand the role of mental health and substance use symptoms among incarcerated Central Appalachian women and build on the conceptual model of substance use treatment utilization purposed by Leukefeld and colleagues (1998). Data for this study was drawn from a larger longitudinal investigation (NIDA 1R01-DA033866) and baseline data collected during initial interviews was analyzed. The sample included 400 women incarcerated at one of …

Pill Poppin’ Nation: Substance Use, Mental Health, And Treatment Among Criminal Justice-Involved African Americans, Joi-Sheree' P. Knighton

Theses and Dissertations--Educational, School, and Counseling Psychology

The purpose of this dissertation was to examine substance use-related outcomes among criminal justice-involved African Americans using a multiple manuscript format. The Centers for Disease Control and Prevention has deemed nonmedical prescription opioid use an epidemic. National estimates indicate approximately 3.9% of African Americans engage in nonmedical prescription opioid use. Research suggests African Americans involved in the criminal justice system may be significantly at risk of substance use more generally; yet, there are no known estimates of nonmedical opioid use among this subgroup. Rising rates of nonmedical opioid use also has implications for discussing barriers to treatment among socioeconomically marginalized …

Active Bystander Behaviors Among High School Students: The Role Of Co-Occurrence Of Violence Victimization And Perpetration In Personal Violence Prevention, Reiko Ozaki

Theses and Dissertations--Social Work

Bystander programs aim to prevent personal violence, such as dating violence, sexual violence, sexual harassment, and stalking. They equip community members with skills to stop the violence before it happens by engaging in active bystander behaviors such as speaking up in potentially risky situations or supporting victims. Given that victimization and perpetration of personal violence, including co-occurrence, are common among youth, high schools have begun implementing bystander programs in recent years. This study examined the relationship between high school students’ experience of personal violence and their active bystander behaviors.

Using the social identity approach as a theoretical foundation, this study …
