This paper examines network prominence in a co-prescription network as an indicator of opioid doctor shopping (i.e., fraudulent solicitation of opioids from multiple prescribers). Using longitudinal data from a large commercially insured population, we construct a network where a tie between patients is weighted by the number of shared opioid prescribers. Given prior research suggesting that doctor shopping may be a social process, we hypothesize that active doctor shoppers will occupy central structural positions in this network. We show that network prominence, operationalized using PageRank, is associated with more opioid prescriptions, higher predicted risk for dangerous morphine dosage, opioid overdose, …


Socioemotional Selectivity And Psychological Health In Amyotrophic Lateral Sclerosis Patients And Caregivers: A Longitudinal, Dyadic Analysis, Suzanne C. Segerstrom, Edward J. Kasarskis, David W. Fardo, Philip M. Westgate Oct 2019

Socioemotional Selectivity And Psychological Health In Amyotrophic Lateral Sclerosis Patients And Caregivers: A Longitudinal, Dyadic Analysis, Suzanne C. Segerstrom, Edward J. Kasarskis, David W. Fardo, Philip M. Westgate

Psychology Faculty Publications

Objective: Socioemotional selectivity theory predicts that as the end of life approaches, goals and resources that provide immediate, hedonic reward become more important than those that provide delayed rewards. This study tested whether these goal domains differentially affected psychological health in the context of marital dyads in which one partner had been diagnosed with amyotrophic lateral sclerosis (ALS), a life-limiting disease.

Design: ALS patients (N = 102) being treated in three multidisciplinary clinics and their spouses (N = 100) reported their loneliness, financial worry and psychological health every 3 months for up to 18 months.

Neural Mechanisms Of The Rejection-Aggression Link, David S. Chester, Donald R. Lynam, Richard Milich, C. Nathan Dewall May 2018

Neural Mechanisms Of The Rejection-Aggression Link, David S. Chester, Donald R. Lynam, Richard Milich, C. Nathan Dewall

Psychology Faculty Publications

Social rejection is a painful event that often increases aggression. However, the neural mechanisms of this rejection–aggression link remain unclear. A potential clue may be that rejected people often recruit the ventrolateral prefrontal cortex’s (VLPFC) self-regulatory processes to manage the pain of rejection. Using functional MRI, we replicated previous links between rejection and activity in the brain’s mentalizing network, social pain network and VLPFC. VLPFC recruitment during rejection was associated with greater activity in the brain’s reward network (i.e. the ventral striatum) when individuals were given an opportunity to retaliate. This retaliation-related striatal response was associated with greater levels of …


Development Of Body Emotion Perception In Infancy: From Discrimination To Recognition, Alison Heck, Alyson Chroust, Hannah B. White, Rachel Lynn Jubran, Ramesh S. Bhatt Feb 2018

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 …


Reproductive Steroids And Adhd Symptoms Across The Menstrual Cycle, Bethan A. Roberts, Tory Eisenlohr-Moul, Michelle M. Martel Feb 2018

Reproductive Steroids And Adhd Symptoms Across The Menstrual Cycle, Bethan A. Roberts, Tory Eisenlohr-Moul, Michelle M. Martel

Psychology Faculty Publications

Although Attention-Deficit/Hyperactivity Disorder shows (ADHD) male predominance, females are significantly impaired and exhibit additional comorbid disorders during adolescence. However, no empirical work has examined the influence of cyclical fluctuating steroids on ADHD symptoms in women. The present study examined estradiol (E2), progesterone (P4), and testosterone (T) associations with ADHD symptoms across the menstrual cycle in regularly-cycling young women (N=32), examining trait impulsivity as a moderator. Women completed a baseline measure of trait impulsivity, provided saliva samples each morning, and completed an ADHD symptom checklist every evening for 35 days. Results indicated decreased levels of E2 in the context of increased …


Measuring Heightened Attention To Alcohol In A Naturalistic Setting: A Validation Study, Ramey G. Monem, Mark T. Fillmore Dec 2017

Measuring Heightened Attention To Alcohol In A Naturalistic Setting: A Validation Study, Ramey G. Monem, Mark T. Fillmore

Psychology Faculty Publications

Attentional bias to alcohol-related stimuli is believed to be an important contributor to the development and maintenance of drug abuse. There is a considerable body of research examining attentional bias, much of which has typically utilized image-display tasks as a means to assess the phenomenon. Little, however, is known about the nature of this bias in an individual’s natural environment. The current study sought to implement a novel approach to assessing attentional bias in vivo. Participants wore portable eye-tracking glasses that recorded video from their point of view and measured fixation time to objects they observed. They entered a room …


Physical Aggressiveness And Gray Matter Deficits In Ventromedial Prefrontal Cortex, David S. Chester, Donald R. Lynam, Richard Milich, C. Nathan Dewall Dec 2017

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 …


A Pilot Study Of Loss Aversion For Drug And Non-Drug Commodities In Cocaine Users, Justin Charles Strickland, Joshua S. Beckmann, Craig R. Rush, William W. Stoops Nov 2017

A Pilot Study Of Loss Aversion For Drug And Non-Drug Commodities In Cocaine Users, Justin Charles Strickland, Joshua S. Beckmann, Craig R. Rush, William W. Stoops

Psychology Faculty Publications

Background—Numerous studies in behavioral economics have demonstrated that individuals are more sensitive to the prospect of a loss than a gain (i.e., loss aversion). Although loss aversion has been well described in “healthy” populations, little research exists in individuals with substance use disorders. This gap is notable considering the prominent role that choice and decision-making play in drug use. The purpose of this pilot study was to evaluate loss aversion in active cocaine users.

Methods—Current cocaine users (N = 38; 42% female) participated in this within-subjects laboratory pilot study. Subjects completed a battery of tasks designed to assess …


High Trait Shame Undermines The Protective Effects Of Prevalence Knowledge On State Shame Following Hpv/Cin Diagnosis In Women, Sarah Mcqueary Flynn, Tory A. Eisenlohr-Moul, Suzanne C. Segerstrom, Christen T. Logue, Jamie L. Studts Oct 2017

High Trait Shame Undermines The Protective Effects Of Prevalence Knowledge On State Shame Following Hpv/Cin Diagnosis In Women, Sarah Mcqueary Flynn, Tory A. Eisenlohr-Moul, Suzanne C. Segerstrom, Christen T. Logue, Jamie L. Studts

Psychology Faculty Publications

Human papillomavirus (HPV), and the related, cervical intraepithelial neoplasia (CIN), are common yet poorly understood physical conditions. The diagnosis of HPV often elicits shame and guilt, which in turn may undermine psychological and physical health. The current study compared shame and guilt responses to diagnosis among two groups: women diagnosed with HPV/CIN and women diagnosed with Epstein–Barr Virus (EBV/IM). Eighty women recently diagnosed with HPV/CIN or EBV/IM completed measures of shame- and guilt-proneness, shame and guilt following diagnosis, and disease knowledge including prevalence estimates (HPV and EBV, respectively). HPV/CIN (vs. EBV/IM) predicted more diagnosis-related shame and guilt. Estimates of high …


A Longitudinal Study Of The Reciprocal Relationship Between Ever Smoking And Urgency In Early Adolescence, Jessica L. Burris, Elizabeth N. Riley, Gabriella E. Puleo, Gregory T. Smith Sep 2017

A Longitudinal Study Of The Reciprocal Relationship Between Ever Smoking And Urgency In Early Adolescence, Jessica L. Burris, Elizabeth N. Riley, Gabriella E. Puleo, Gregory T. Smith

Psychology Faculty Publications

Background—Among early adolescents in the United States (U.S.), the prevalence of cigarette smoking is at its lowest level in recent decades. Nonetheless, given the risks of smoking in early development, it remains critically important to study both risk factors for smoking and risks from smoking. This longitudinal study with U.S. early adolescents examines smoking initiation and tests a model of reciprocal prediction between ever smoking and the personality trait of urgency (i.e., mood-based impulsivity), a trait that increases risk for multiple forms of dysfunction.

Methods—Participants (n=1906; 90% 10–11 years old, 50% female, 39% racial minorities at …

Effectiveness Of Switching Smoking-Cessation Medications Following Relapse, Bryan W. Heckman, K. Michael Cummings, Karin A. Kasza, Ron Borland, Jessica L. Burris, Geoffrey T. Fong, Ann Mcneill, Matthew J. Carpenter

Psychology Faculty Publications

Introduction—Nicotine dependence is a chronic disorder often characterized by multiple failed quit attempts (QAs). Yet, little is known about the sequence of methods used across multiple QAs or how this may impact future ability to abstain from smoking. This prospective cohort study examines the effectiveness of switching smoking-cessation medications (SCMs) across multiple QAs.

Methods—Adult smokers (aged ≥ 18 years) participating in International Tobacco Control surveys in the United Kingdom, U.S., Canada, and Australia (N=795) who: (1) completed two consecutive surveys between 2006 and 2011; (2) initiated a QA at least 1 month before each survey; and (3) provided …


Social Rejection Magnifies Impulsive Behavior Among Individuals With Greater Negative Urgency: An Experimental Test Of Urgency Theory, David S. Chester, Donald R. Lynam, Richard S. Milich, C. Nathan Dewall Jul 2017

Social Rejection Magnifies Impulsive Behavior Among Individuals With Greater Negative Urgency: An Experimental Test Of Urgency Theory, David S. Chester, Donald R. Lynam, Richard S. Milich, C. Nathan Dewall

Psychology Faculty Publications

Impulsivity is a multifaceted trait with substantial implications for human well-being. One facet of impulsivity is negative urgency, the tendency to act impulsively in response to negative affect. Correlational evidence suggests that negative affect magnifies impulsive behavior among individuals with greater negative urgency, yet causal evidence for this core pillar of urgency theory is lacking. To fill this gap in the literature, participants (N = 363) were randomly assigned to experience social rejection (a situation shown to induce negative affect) or acceptance. Participants then reported their subjective negative affect, completed a behavioral measure of impulsivity, and reported their negative …


Laboratory Analysis Of Risky Driving At 0.05% And 0.08% Blood Alcohol Concentration, Nicholas A. Van Dyke, Mark T. Fillmore Jun 2017

Laboratory Analysis Of Risky Driving At 0.05% And 0.08% Blood Alcohol Concentration, Nicholas A. Van Dyke, Mark T. Fillmore

Psychology Faculty Publications

Background—The public health costs associated with alcohol-related traffic crashes are a continuing problem for society. One harm reduction strategy has been to employ per se limits for blood alcohol concentrations (BACs) at which drivers can legally operate motor vehicles. This limit is currently 0.08% in all 50 US states. Recently, the National Transportation Safety Board proposed lowering the legal limit to 0.05 % (NTSB, 2013). While research has well-validated the ability of alcohol to impair driving performance and heighten crash-risk at these BACs, relatively little is known about the degree to which alcohol might increase drivers’ risk-taking.

Methods—Risk-taking …

Habituation Of Distress And Craving During Treatment As Predictors Of Change In Ptsd Symptoms And Substance Use Severity, Christal L. Badour, Julianne C. Flanagan, Daniel F. Gros, Therese Killeen, Irene Pericot-Valverde, Kristina J. Korte, Nicholas P. Allan, Sudie E. Back

Psychology Faculty Publications

Objective—Increasing evidence supports the efficacy of trauma-focused exposure therapy in the treatment of posttraumatic stress disorder (PTSD) and co-occurring substance use disorders. Little is known, however, about the mechanisms of change in treatment for patients with PTSD and co-occurring substance use disorders. The aim of the present study was to examine whether within- and between-session habituation of distress and substance craving during imaginal exposure relates to treatment outcomes among U.S. military veterans with PTSD and a co-occurring substance use disorder (N = 54).

Method—Veterans received Concurrent Treatment of PTSD and Substance Use Disorders Using Prolonged Exposure, a manualized …


Faster Self-Paced Rate Of Drinking For Alcohol Mixed With Energy Drinks Versus Alcohol Alone, Cecile A. Marczinski, Mark T. Fillmore, Sarah F. Maloney, Amy L. Stamates Mar 2017

Faster Self-Paced Rate Of Drinking For Alcohol Mixed With Energy Drinks Versus Alcohol Alone, Cecile A. Marczinski, Mark T. Fillmore, Sarah F. Maloney, Amy L. Stamates

Psychology Faculty Publications

The consumption of alcohol mixed with energy drinks (AmED) has been associated with higher rates of binge drinking and impaired driving when compared with alcohol alone. However, it remains unclear why the risks of use of AmED are heightened compared with alcohol alone even when the doses of alcohol consumed are similar. Therefore, the purpose of this laboratory study was to investigate if the rate of self-paced beverage consumption was faster for a dose of AmED versus alcohol alone using a double-blind, within-subjects, placebo-controlled study design. Participants (n = 16) of equal gender who were social drinkers attended 4 separate …


Curbing The Dui Offender's Self-Efficacy To Drink And Drive: A Laboratory Study, Walter Roberts, Mark T. Fillmore Mar 2017

Curbing The Dui Offender's Self-Efficacy To Drink And Drive: A Laboratory Study, Walter Roberts, Mark T. Fillmore

Psychology Faculty Publications

Background—People arrested for driving under the influence of alcohol (DUI) are at high risk to reoffend. One reason for this high rate of recidivism among DUI offenders is that these individuals systematically underestimate the degree to which alcohol impairs their ability to drive. This study compared perceived and objective driving ability following alcohol and performance feedback in drivers with and without a history of DUI.

Method—Adult drivers with (n = 20) and without (n = 20) a history of DUI arrest attended two dose challenge sessions where they received 0.64 g/kg alcohol or placebo, completed a simulated driving …

Cytomegalovirus Serostatus, Inflammation, And Antibody Response To Influenza Vaccination In Older Adults: The Moderating Effect Of Beta Blockade, Rebecca G. Reed, Richard N. Greenberg, Suzanne C. Segerstrom

Psychology Faculty Publications

Cytomegalovirus (CMV) has been implicated as a factor in immunosenescence, including poor antibody response to vaccination and higher immune activation and inflammation. Some people may be more or less vulnerable to the negative effects of CMV. The present investigation tested the effects of beta-blocker use and chronological age on the associations between CMV and immunity in adults aged 60–91 (N=98; 69% CMV seropositive) who were administered the trivalent influenza vaccine for up to 5 years. Peak antibody response, corrected for baseline, and spring (persistent) antibody response, corrected for peak, were assessed, as well as beta-2 microglobulin (β2μ) and interleukin-6 (IL-6). …

Subjective Report Of Side Effects Of Prescribed And Nonprescribed Psychostimulant Use In Young Adults, Tess E. Smith, Michelle M. Martel, Alan D. Desantis

Psychology Faculty Publications

Background: Side effects of prescribed and nonprescribed psychostimulant use are understudied. Objectives: The study examined side effects of prescribed and nonprescribed psychostimulant use in a college sample with attention to possible gender differences. Methods: 2716 undergraduates (1448 male) between the ages of 17 and 57 years (M = 19.43 years, SD = 1.7 years) completed an online survey that included questions about the subjective side effects of prescribed and nonprescribed psychostimulant use. Results: Results suggested that prescribed users more frequently reported side effects, compared to nonprescribed users. For prescribed users, females more frequently reported appetite, somatic, and anxiety-related side …
