The Role Of Stress In The Pathogenesis And Maintenance Of Obsessive-Compulsive Disorder, Thomas G. Adams, Benjamin Kelmendi, C. Alex Brake, Patricia Gruner, Christal L. Badour, Christopher Pittenger

Psychology Faculty Publications

Individuals with obsessive-compulsive disorder often identify psychosocial stress as a factor that exacerbates their symptoms, and many trace the onset of symptoms to a stressful period of life or a discrete traumatic incident. However, the pathophysiological relationship between stress and obsessive-compulsive disorder remains poorly characterized: it is unclear whether trauma or stress is an independent cause of obsessive-compulsive disorder symptoms, a triggering factor that interacts with a preexisting diathesis, or simply a nonspecific factor that can exacerbate obsessive-compulsive disorder along with other aspects of psychiatric symptomatology. Nonetheless, preclinical research has demonstrated that stress has conspicuous effects on corticostriatal and limbic …

Development Of Body Emotion Perception In Infancy: From Discrimination To Recognition, Alison Heck, Alyson Chroust, Hannah B. White, Rachel Lynn Jubran, Ramesh S. Bhatt

Psychology Faculty Publications

Research suggests that infants progress from discrimination to recognition of emotions in faces during the first half year of life. It is unknown whether the perception of emotions from bodies develops in a similar manner. In the current study, when presented with happy and angry body videos and voices, 5-month-olds looked longer at the matching video when they were presented upright but not when they were inverted. In contrast, 3.5-month-olds failed to match even with upright videos. Thus, 5-month-olds but not 3.5-month-olds exhibited evidence of recognition of emotions from bodies by demonstrating intermodal matching. In a subsequent experiment, younger infants …

The Rewarding Nature Of Provocation-Focused Rumination In Women With Borderline Personality Disorder: A Preliminary Fmri Investigation, Jessica R. Peters, David S. Chester, Erin C. Walsh, C. Nathan Dewall, Ruth A. Baer

Psychology Faculty Publications

Background: Understanding why individuals with borderline personality disorder (BPD) ruminate on prior provocations, despite its negative outcomes, is crucial to improving interventions. Provocation-focused rumination may be rewarding in the short term by amplifying anger and producing feelings of justification, validation, and increased energy, while reducing self-directed negative affect. If provocation-focused rumination is utilized regularly as a rewarding emotion regulation strategy, it could result in increased activation in reward-related neural regions. The present pilot study examined neural correlates of provocation-focused rumination, relative to other forms of thought, in BPD.

Method: Functional magnetic resonance imaging (fMRI) was utilized to examine this theory …

Sexual Coercion, Drinking To Cope Motives, And Alcohol-Related Consequences Among Self-Identified Bisexual Women, Michelle L. Kelly, Sarah J. Ehlke, Robin J. Lewis, Abby L. Braitman, Wendy Bostwick, Kristin E. Heron, Cathy Lau-Barraco

Psychology Faculty Publications

Background: Given higher sexual victimization and greater alcohol use among bisexual women, a critical public health challenge is to understand within-group variation that may heighten or explain these associations in bisexual women. Objectives: The present study tested a moderated-mediation model in which sexual coercion was hypothesized to be associated with alcohol-related consequences via drinking to cope motives in self-identified bisexual women who reported at least occasional binge drinking. Negative affect was hypothesized to moderate the sexual coercion-drinking to cope motives association. Methods: Participants were a community sample of 107 self-identified bisexual women (age M = 20.97, SD = 2.11) who …

Independent And Interactive Associations Of Negative Affect, Restraint, And Impulsivity In Relation To Binge Eating Among Women, Tyler B. Mason, Kathryn E. Smith, Jason M. Lavender, Robin J. Lewis

Psychology Faculty Publications

There is growing recognition that impulsivity may serve as an underlying risk factor for binge eating. In addition, the association of impulsivity with binge eating may be moderated by other affective and cognitive risk factors. This study examined independent and interactive associations of negative affect, dietary restraint, and facets of impulsivity with binge eating. A diverse sample of 566 undergraduate women completed online questionnaires of study variables. Results revealed a three-way interaction of negative affect, dietary restraint, and attentional impulsivity in relation to binge eating. Women who were high on each of these three variables reported the greatest levels of …

Measuring Sexual Minority Stressors In Lesbians Women's Daily Lives: Initial Scale Development, Kristin Heron, Abby L. Braitman, Robin J. Lewis, Alexander T. Shappie, Phoebe T. Hitson

Psychology Faculty Publications

Lesbian women face unique sexual minority stressors (SMS) because of their stigmatized and marginalized status in society. Existing studies of SMS are primarily cross-sectional and use global measures of SMS. The goal of the present study was to develop a brief daily measure of SMS for use in daily diary or ecological momentary assessment studies. Existing retrospective measures of SMS were reviewed, resulting in an initial pool of 29 items. Thirty-eight lesbian women (Mage = 24.3 years, range: 19–30 years) completed a daily web-based survey including the SMS items for 12 days. Two response scales were tested; participants were randomized …
