Item Integrating affect and impulsivity: The role of positive and negative urgency in substance use risk(Elsevier, 2016-06-01) Smith, Gregory T.; Cyders, Melissa A.; Psychology, School of ScienceBACKGROUND: The personality traits of positive and negative urgency refer to the tendencies to act rashly when experiencing unusually positive or negative emotions, respectively. METHODS: The authors review recent empirical work testing urgency theory (Cyders and Smith, 2008a) and consider advances in theory related to these traits. RESULTS: Empirical findings indicate that (a) the urgency traits are particularly important predictors of the onset of, and increases in, substance use in both children and young adults; (b) they appear to operate in part by biasing psychosocial learning; (c) pubertal onset is associated with increases in negative urgency, which in turn predict increases in adolescent drinking behavior; (d) variation in negative urgency trait levels are associated with variations in the functioning of an identified brain system; and (e) variations in the serotonin transporter gene, known to influence the relevant brain system, relate to variations in the urgency traits. CONCLUSION: A recent model (Carver et al., 2008) proposes the urgency traits to be markers of a tendency to respond reflexively to emotion, whether through impulsive action or ill-advised inaction (the latter leading to depressive symptoms); this model has received empirical support. The authors discuss new directions for research on the urgency traits.Item A longitudinal test of impulsivity and depression pathways to early binge eating onset(Wiley, 2015-03) Pearson, Carolyn M.; Zapolski, Tamika C.B.; Smith, Gregory T.; Department of Psychology, School of ScienceOBJECTIVE: The very early engagement in bulimic behaviors, such as binge eating, may be influenced by factors that dispose individuals to impulsive action as well as by factors that dispose individuals to depressive symptomatology. Using a longitudinal design, we conducted the first test of the simultaneous operation of both risk factors as children transition from elementary to middle school. METHOD: In a sample of 1,906 children, we assessed risk for impulsive action (negative urgency, which is the tendency to act rashly when distressed, and eating expectancies, which are learned anticipations that eating will alleviate negative mood) and risk for depression (negative affect and depressive symptomatology) and binge eating behavior at three time points using a longitudinal design: the end of fifth grade (last year of elementary school: T0), the beginning of sixth grade (first year of middle school: T1), and the end of sixth grade (T2). RESULTS: Both the impulsive action and depression pathways predicted very early engagement in binge eating: each accounted for variance beyond the other. Mediation tests found that T1 eating expectancies mediated the predictive influence of T0 negative urgency on T2 binge eating (z = 2.45, p < .01) and that T1 depressive symptoms mediated the influence of T0 negative affect on T2 binge eating (z = 2.04, p < .05). DISCUSSION: In children, elevated levels of both negative urgency and negative affect predict early binge eating. This finding has important clinical implications because there are different interventions for the two different risk processes.Item Pilot Study: Implementing a Brief DBT Skills Program in Schools to Reduce Health Risk Behaviors Among Early Adolescents(Sage, 2017) Zapolski, Tamika C. B.; Smith, Gregory T.; Psychology, School of ScienceA significant proportion of youth engage in health risk behaviors, which are of concern, as they are associated with adverse health consequences across development. Two factors associated with engagement in such behaviors are emotion dysregulation and impulsivity. Dialectical behavioral therapy (DBT) is an effective intervention that enhances emotion regulation skills to reduce problem behaviors among adolescent populations; however, limited research has been conducted implementing the program within school settings. The current study was a 9-week DBT skills group conducted among 80 middle school youth, with pre–posttest data among 53 students. Findings indicated feasibility to implement the program in schools and preliminary evidence of efficacy in decreasing youth’s likelihood to engage in risky, particularly among youth high on an emotion-based impulsivity trait. Brief DBT skills group may be an effective program to be utilized by school nurses and health-care teams to reduce health risk behaviors among school-aged youth.Item Problematic alcohol use and sexting as risk factors for sexual assault among college women(Taylor & Francis, 2018-10) Dir, Allyson L.; Riley, Elizabeth N.; Cyders, Melissa A.; Smith, Gregory T.; Pediatrics, School of MedicineSexual assault is a major public health concern and college women are four times more likely to experience sexual assault than any other group. We investigated whether sexting is a mechanism by which alcohol use increases risk for college women to be targeted for sexual assault. We hypothesized that sexting would mediate the relationship between problem drinking and sexual assault, such that drinking (T1 = beginning fall semester) would contribute to increased sexting (T2 = end fall semester), and in turn increase the risk of being targeted for sexual assault (T3 = end spring semester). Results: Among 332 undergraduate women (M(SD)age = 19.15(1.69), 76.9% Caucasian), sexting (T2) predicted sexual assault (T3; b = 3.98, p = .05), controlling for baseline sexual assault (b = 0.82, p < .01). Further, sexting (T2) mediated the relationship between problem drinking (T1) and sexual assault (T3) (b = 0.04, CI[.004,.12]). Conclusion: Findings suggest that sexting is one mechanism through which drinking increases the risk of college women being targeted for sexual assault.Item Racial Differences in the Transactional Relationship Between Depression and Alcohol Use From Elementary School to Middle School(Rutgers Center of Alcohol Studies, 2015-09) Birkley, Erica L.; Zapolski, Tamika C.B.; Smith, Gregory T.; Department of Psychology, School of ScienceObjective: The aim of this investigation was to test hypothesized reverse prospective relationships between alcohol consumption and depressive symptomatology as a function of race among youth. Method: In a two-wave prospective study, 328 European American, 328 African American, and 144 Hispanic American youth were studied at the end of fifth grade (last year of elementary school) and the end of sixth grade (first year of middle school). Results: A positive correlation was observed between alcohol consumption and depressive symptoms among all youth. However, the predictive relationship differed based on race. For European American and Hispanic American youth, depressive symptom levels at the end of elementary school predicted alcohol consumption at the end of the first year of middle school, but the converse relationship was not observed. For African American youth, the opposite pattern was found. Alcohol consumption at the end of elementary school predicted depressive symptom levels at the end of the first year of middle school, and the converse relationship was not observed. Conclusions: These findings suggest the possibility that etiological relationships between depression and alcohol use vary by race, thus highlighting the importance of considering race when studying the risk process.Item Racial/ethnic differences in the time-varying association between alcohol expectancies and drinking during the transition from childhood to adolescence(Taylor & Francis, 2020-04-22) Banks, Devin E.; Faidley, Micah T.; Smith, Gregory T.; Zapolski, Tamika C. B.; Psychology, School of ScienceAlcohol expectancies are important determinants of adolescent drinking, but this relationship may differ based on race/ethnicity. This study used time-varying effect modeling to examine racial/ethnic differences in positive and negative alcohol expectancies and their relationship with drinking among White, African American, and Hispanic youth. Youth reported alcohol expectancies and drinking frequency from 5th-10th grade. African Americans initially endorsed higher positive alcohol expectancies than Whites, but its relationship with drinking was stronger among Whites. Hispanic youth reported slightly higher negative alcohol expectancies in high school, but the relationship between negative expectancies and alcohol use was comparable across groups. The effect of expectancies on alcohol use outcomes may be more robust for Whites, which warrants investigation of risk factors for minority youth.Item Response to the COVID-19 Pandemic Among Posthospital Brain Injury Rehabilitation Providers(Elsevier, 2020-12-27) Malec, James F.; Salisbury, David B.; Anders, David; Dennis, Leanne; Groff, April R.; Johnson, Margaret; Murphy, Mary Pat; Smith, Gregory T.; Physical Medicine and Rehabilitation, School of MedicineRehabilitation after significant acquired brain injury (ABI) to address complex independent activities of daily living and return to family and community life is offered primarily after initial hospitalization in outpatient day treatment, group home, skilled nursing, and residential settings and in the home and community of the person served. The coronavirus 2019 pandemic threatened access to care and the health and safety of staff, persons served, and families in these settings. This article describes steps taken to contain this threat by 7 leading posthospital ABI rehabilitation organizations. Outpatient and day treatment facilities were temporarily suspended. In other settings, procedures for isolation, transportation, cleaning, exposure control, infection control, and use of personal protective equipment (PPE) were reinforced with staff. Visitation and community activities were restricted. Staff and others required to enter facilities were screened with symptom checklists and temperature checks. Individuals showing symptoms of infection were quarantined and tested, as possible. New admissions were carefully screened for infection and often initially quarantined. Telehealth played a major role in reducing direct interpersonal contact while continuing to provide services both to outpatients and within facilities. Salary, benefits, training, and managerial support were enhanced for staff. Despite early outbreaks, these procedures were generally effective, with preliminary initial infections rates of only 1.1% for persons served and 2.1% for staff. Reductions in admissions, services, and unanticipated expenses (eg, PPE, more frequent and thorough cleaning) had a major negative financial effect. Providers continue to be challenged to adapt rehabilitative approaches and to reopen services.
