Caregiver Participation Engagement In Child Mental Health Prevention Programs: A Systematic Review, Rachel Haine‑Schlagel, Kelsey S. Dickson, Teresa Lind, Joanna J. Kim, Gina C. May, Natalia Escobar Walsh, Vanja Lazarevic, Brent R. Crandal, May Yeh

Department of Psychology: Faculty Publications

Prevention programs are a key method to reduce the prevalence and impact of mental health disorders in childhood and adolescence. Caregiver participation engagement (CPE), which includes caregiver participation in sessions as well as follow-through with homework plans, is theorized to be an important component in the effectiveness of these programs. This systematic review aims to (1) describe the terms used to operationalize CPE and the measurement of CPE in prevention programs, (2) identify factors associated with CPE, (3) examine associations between CPE and outcomes, and (4) explore the effects of strategies used to enhance CPE. Thirty-nine articles representing 27 unique …


The Importance Of Acquisition Learning On Nicotine And Varenicline Drug Substitution In A Drug-Discriminated Goal-Tracking Task, Brady M. Thompson, Scott T. Barrett, Y. Wendy Huynh, David A. Kwan, Jennifer E. Murray, Rick A. Bevins Dec 2021

The Importance Of Acquisition Learning On Nicotine And Varenicline Drug Substitution In A Drug-Discriminated Goal-Tracking Task, Brady M. Thompson, Scott T. Barrett, Y. Wendy Huynh, David A. Kwan, Jennifer E. Murray, Rick A. Bevins

Department of Psychology: Faculty Publications

Nicotine and varenicline (Chantix®; the leading non-nicotine cessation pharmacotherapy) can come to control appetitive behaviors such as goal-tracking. We tested rats (N = 48) in a drug-discriminated goal-tracking (DGT) task where each rat received daily subcutaneous injections of either nicotine (0.4 mg/kg) or saline (0.9% [w/v]) interspersed across the acquisition phase (Phase 1). On saline days, sucrose was intermittently available. On nicotine days, sucrose was withheld. All rats acquired the discrimination with increased goal-tracking rates on saline days relative to nicotine days. Following acquisition, rats were separated into four groups to assess drug-substitution and discrimination reversal in Phase 2. The …


Dimension- And Context-Specific Expression Of Preschoolers’ Disruptive Behaviors Associated With Prenatal Tobacco Exposure, Suena H. Massey, Caron A.C. Clark, Michael Y. Sun, James L. Burns, Daniel K. Mroczek, Kimberly A. Espy, Lauren S. Wakschlag Sep 2021

Dimension- And Context-Specific Expression Of Preschoolers’ Disruptive Behaviors Associated With Prenatal Tobacco Exposure, Suena H. Massey, Caron A.C. Clark, Michael Y. Sun, James L. Burns, Daniel K. Mroczek, Kimberly A. Espy, Lauren S. Wakschlag

Department of Psychology: Faculty Publications

Objective—Precise phenotypic characterization of prenatal tobacco exposure (PTE) −related disruptive behavior (DB) that integrates nuanced measures of both exposures and outcomes is optimal for elucidating underlying mechanisms. Using this approach, our goals were to identify dimensions of DB most sensitive to PTE prior to school entry and assess contextual variation in these dimensions.

Methods—A community obstetric sample of N=369 women (79.2% lifetime smokers; 70.2% pregnancy smokers) from two Midwestern cities were assessed for PTE using cotinine-calibrated interview-based reports at 16, 28, and 40 weeks of gestation. A subset of n=244 who completed observational assessments with their …


A Prospective Study Of Predictors And Consequences Of Hooking Up For Sexual Minority Women, Anna E. Jaffe, Jennifer Duckworth, Jessica A. Blayney, Melissa A. Lewis, Debra Kaysen May 2021

A Prospective Study Of Predictors And Consequences Of Hooking Up For Sexual Minority Women, Anna E. Jaffe, Jennifer Duckworth, Jessica A. Blayney, Melissa A. Lewis, Debra Kaysen

Department of Psychology: Faculty Publications

Hooking up, which refers to a sexual encounter (ranging from kissing to penetrative sex) between individuals who are not in a committed relationship, is an increasingly normative form of sexual exploration among emerging adults. Past research has focused on hookups within a heteronormative context, and some of this work has examined hookups as a way to cope with distress. Building on this work, we examined the role of hookups as a means for lesbian and bisexual women to cope with minority stress through increasing connection and engagement with the LGBTQ (lesbian/gay/bisexual/transgender/queer or questioning) community. A nationally recruited sample of 520 …


Testing The Use Of A Social Networking App For American Indians Recovering From Addiction, Nicholas Guenzel, Dennis Mcchargue, Hongying Dai Feb 2021

Testing The Use Of A Social Networking App For American Indians Recovering From Addiction, Nicholas Guenzel, Dennis Mcchargue, Hongying Dai

Department of Psychology: Faculty Publications

Objectives: American Indians (AIs) have higher rates of addiction than most other groups. Social networking mobile apps are growing in popularity but their use has not been studied among AIs specifically. Methods: This paper describes a pilot program in which 27 AIs recovering from addiction were given access to a mobile app to support addiction recovery (Sober Grid) for up to six months. They completed a technology acceptability survey, monthly surveys of cravings, social connectedness, and quality of life, and a follow-up survey. Their use of the app was also tracked. Findings: We found that individuals in the sample often …


Female Rats Display Higher Methamphetamine-Primed Reinstatement And C-Fos Immunoreactivity Than Male Rats, Steven T. Pittenger, Shinnyi Chou, Nathan J. Murawski, Scott T. Barrett, Olivia Loh, Juan F. Duque, Ming Li, Rick A. Bevins Feb 2021

Female Rats Display Higher Methamphetamine-Primed Reinstatement And C-Fos Immunoreactivity Than Male Rats, Steven T. Pittenger, Shinnyi Chou, Nathan J. Murawski, Scott T. Barrett, Olivia Loh, Juan F. Duque, Ming Li, Rick A. Bevins

Department of Psychology: Faculty Publications

Methamphetamine (meth) dependence is often characterized by persistent and chronic relapse (i.e., return to drug use). Previous work suggests females may be at greater risk to relapse. In this study, we extended this limited evidence and identified sex-dependent neural substrates related to meth-triggered reinstatement. Male and female Sprague-Dawley rats were implanted with indwelling jugular catheters. Half of the rats were then trained to self-administer meth (0.05 mg/kg/inf); the other half self-administered saline during 21 daily sessions (2 h). Rats were then given 12 extinction sessions. Twenty-four hours after the last extinction session, rats received reinstatement testing. Half of the rats …


Factors Associated With Smoking In Low-Income Persons With And Without Chronic Illness, Monique T. Cano, David L. Pennington, Sara Reyes, Blanca S. Pineda, Jazmin Llamas, Vyjeyanthi S. Periyakoil, Ricardo F. Muñoz Jan 2021

Factors Associated With Smoking In Low-Income Persons With And Without Chronic Illness, Monique T. Cano, David L. Pennington, Sara Reyes, Blanca S. Pineda, Jazmin Llamas, Vyjeyanthi S. Periyakoil, Ricardo F. Muñoz

Department of Psychology: Faculty Publications

INTRODUCTION Tobacco disparities persist among low-income smokers who seek care from safety-net clinics. Many of these patients suffer from chronic illnesses (CILs) that are associated with and exacerbated by smoking. The objective of the current study was to examine the differences between safety-net patients with and without CILs in terms of nicotine dependence and related factors (such as depression, anxiety) and self-efficacy regarding ability to abstain from smoking. METHODS Sixty-four low-income smokers who thought about or intended to quit smoking were recruited from the San Francisco Health Network (SFHN) and assessed for CILs, nicotine dependence, depression, anxiety, and smoking abstinence …


Does Self-Objectification Entail An Opposition Between Appearance And Competence? The Likert Version Of The Self-Objectification Questionnaire (Lsoq), Robin Wollast, Oliver Klein, Dawn M. Vanleeuwen, Sarah J. Gervais, Philippe Bernard Jan 2021

Does Self-Objectification Entail An Opposition Between Appearance And Competence? The Likert Version Of The Self-Objectification Questionnaire (Lsoq), Robin Wollast, Oliver Klein, Dawn M. Vanleeuwen, Sarah J. Gervais, Philippe Bernard

Department of Psychology: Faculty Publications

We propose a new method to test the reliability of Fredrickson et al.’s self-objectification questionnaire (SOQ). This scale being based on a ranking, traditional reliability estimates are inappropriate. Based on generalizability theory, we suggest to compute the reliability of each subset of questions related to physical appearance vs. physical competence separately in order to average them. We applied this method to a sample of female US undergraduates (n = 395) and evidenced that the reliability of the scale is very low (corrected Cronbach’s alpha = .31). We also noted that a large proportion of the sample (32%) failed to …

A Comprehensive Study To Delineate The Role Of An Extracellular Vesicle-Associated Microrna-29a In Chronic Methamphetamine Use Disorder, Subhash Chand, Austin Gowen, Mason Savine, Dalia Moore, Alexander Clark, Wendy Huynh, Niming Wu, Katherine Odegaard, Lucas Weyrich, Rick A. Bevins, Howard S. Fox, Gurudutt Pendyala, Sowmya V. Yelamanchili

Department of Psychology: Faculty Publications

Extracellular vesicles (EVs), which express a repertoire of cargo molecules (cf. proteins, microRNA, lipids, etc.), have been garnering a prominent role in the modulation of several cellular processes. Here, using both non-human primate and rodent model systems, we provide evidence that brain-derived EV (BDE) miRNA, miR- 29a-3p (mir-29a), is significantly increased during chronic methamphetamine (MA) exposure. Further, miR-29a levels show significant increase both with drug-seeking and reinstatement in a rat MA self-administration model. We also show that EVassociated miR-29a is enriched in EV pool comprising of small EVs and exomeres and further plays a critical role in MA-induced inflammation and …


Nontarget Emotional Stimuli Must Be Highly Conspicuous To Modulate The Attentional Blink, Lindsay A. Santacroce, Brandon J. Carlos, Nathan Petro, Benjamin J. Tamber-Rosenau Jan 2021

Nontarget Emotional Stimuli Must Be Highly Conspicuous To Modulate The Attentional Blink, Lindsay A. Santacroce, Brandon J. Carlos, Nathan Petro, Benjamin J. Tamber-Rosenau

Department of Psychology: Faculty Publications

The attentional blink (AB) is often considered a top-down phenomenon because it is triggered by matching an initial target (T1) in a rapid serial visual presentation (RSVP) stream to a search template. However, the AB is modulated when targets are emotional, and is evoked when a task-irrelevant, emotional critical distractor (CDI) replaces T1. Neither manipulation fully captures the interplay between bottom-up and top-down attention in the AB: Valenced targets intrinsically conflate top-down and bottom-up attention. The CDI approach cannotmanipulate second target (T2) valence, which is critical because valenced T2s can “break through” the AB (in the target-manipulation approach). The present …


An Examination Of The Relations Between Emotion Dysregulation, Dissociation, And Self-Injury Among Dissociative Disorder Patients, M. Shae Nester, Bethany L. Brand, Hugo J. Schielke, Shaina Kumar Jan 2021

An Examination Of The Relations Between Emotion Dysregulation, Dissociation, And Self-Injury Among Dissociative Disorder Patients, M. Shae Nester, Bethany L. Brand, Hugo J. Schielke, Shaina Kumar

Department of Psychology: Faculty Publications

Background: Dissociative disorder (DD) patients report high rates of self-injury. Previous studies have found dissociation and self-injury to be related to emotional distress. To the best of our knowledge, however, the link between emotion dysregulation and self-injury has not yet been examined within a DD population. Objective: The present study investigated relations between emotion dysregulation, dissociation, and self-injury in DD patients, and explored patterns of emotion dysregulation difficulties among DD patients with and without recent histories of self-injury. Method: We utilized linear and logistic regressions and t-test statistical methods to examine data from 235 patient-clinician dyads enrolled …


The Truth About Snitches: An Archival Analysis Of Informant Testimony, Jeffrey S. Neuschatz, Danielle K. Deloach, Megan A. Hillgartner, Melanie Fessinger, Stacy A. Wetmore, Amy B. Douglass, Brian H. Bornstein, Alexis M. Le Grand Jan 2021

The Truth About Snitches: An Archival Analysis Of Informant Testimony, Jeffrey S. Neuschatz, Danielle K. Deloach, Megan A. Hillgartner, Melanie Fessinger, Stacy A. Wetmore, Amy B. Douglass, Brian H. Bornstein, Alexis M. Le Grand

Department of Psychology: Faculty Publications

Informants are witnesses who often testify in exchange for an incentive (i.e. jailhouse informant, cooperating witness). Despite the widespread use of informants, little is known about the circumstances surrounding their use at trial. This study content-analyzed trials from 22 DNA exoneration cases involving 53 informants. Because these defendants were exonerated, the prosecution informant testimony is demonstrably false. Informant characteristics including motivation for testifying, criminal history, relationship with the defendant and testimony were coded. Most informants were prosecution jailhouse informants; however, there were also defence jailhouse informants and prosecution cooperating witnesses. Regardless of informant type, most denied receiving an incentive, had …

Trust In The Jury System: A Comparison Of Australian And U.S. Samples, Monica K. Miller, Jeffrey Pfeifer, Brian H. Bornstein, Tatyana Kaplan

Department of Psychology: Faculty Publications

Public trust in the criminal justice system, including the jury system, is important for maintaining a democracy that is fair for all citizens. However, there is little research on trust in the jury system generally and even less cross-country comparison research specifically. Trust in the jury system might relate to other legal attitude measures (e.g., authoritarianism). This study identified the degree to which trust in the jury system relates to legal attitudes and compared perceptions of trust between the U.S. and Australia. Community members completed a survey that included measures of trust in the jury system and legal attitudes. The …


Probabilistic Mapping Of Human Functional Brain Networks Identifies Regions Of High Group Consensus, Ally Dworetsky, Benjamin A. Seitzman, Babatunde Adeyemo, Maital Neta, Rebecca S. Coalson, Steven E. Petersen, Caterina Gratton Jan 2021

Probabilistic Mapping Of Human Functional Brain Networks Identifies Regions Of High Group Consensus, Ally Dworetsky, Benjamin A. Seitzman, Babatunde Adeyemo, Maital Neta, Rebecca S. Coalson, Steven E. Petersen, Caterina Gratton

Department of Psychology: Faculty Publications

Many recent developments surrounding the functional network organization of the human brain have focused on data that have been averaged across groups of individuals. While such group-level approaches have shed considerable light on the brain’s large-scale distributed systems, they conceal individual differences in network organization, which recent work has demonstrated to be common and widespread. This individual variability produces noise in group analyses, which may average together regions that are part of different functional systems across participants, limiting interpretability. However, cost and feasibility constraints may limit the possibility for individual-level mapping within studies. Here our goal was to leverage information …


Reappraisal—But Not Suppression—Tendencies Determine Negativity Bias After Laboratory And Real‑World Stress Exposure, Candace M. Raio, Nicholas R. Harp, Catherine C. Brown, Maital Neta Jan 2021

Reappraisal—But Not Suppression—Tendencies Determine Negativity Bias After Laboratory And Real‑World Stress Exposure, Candace M. Raio, Nicholas R. Harp, Catherine C. Brown, Maital Neta

Department of Psychology: Faculty Publications

Higher reactivity to stress exposure is associated with an increased tendency to appraise ambiguous stimuli as negative. However, it remains unknown whether tendencies to use emotion regulation strategies—such as cognitive reappraisal, which involves altering the meaning or relevance of affective stimuli—can shape individual differences regarding how stress affects perceptions of ambiguity. Here, we examined whether increased reappraisal use is one factor that can determine whether stress exposure induces increased negativity bias. In Study 1, healthy participants (n = 43) rated the valence of emotionally ambiguous (surprised) faces before and after an acute stress or control manipulation and reported reappraisal …


Social Connectedness And Negative Affect Uniquely Explain Individual Differences In Response To Emotional Ambiguity, Maital Neta, Rebecca L. Brock Jan 2021

Social Connectedness And Negative Affect Uniquely Explain Individual Differences In Response To Emotional Ambiguity, Maital Neta, Rebecca L. Brock

Department of Psychology: Faculty Publications

Negativity bias is not only central to mood and anxiety disorders, but can powerfully impact our decision-making across domains (e.g., financial, medical, social). This project builds on previous work examining negativity bias using dual-valence ambiguity. Specifically, although some facial expressions have a relatively clear negative (angry) or positive valence (happy), surprised expressions are interpreted negatively by some and positively by others, providing insight into one’s valence bias. Here, we examine putative sources of variability that distinguish individuals with a more negative versus positive valence bias using structural equation modeling. Our model reveals that one’s propensity toward negativity (operationalized as temperamental …


Much Ado About Missingness: A Demonstration Of Full Information Maximum Likelihood Estimation To Address Missingness In Functional Magnetic Resonance Imaging Data, Timothy D. Nelson, Rebecca L. Brock, Sonja Yokum, Cara C. Tomaso, Cary R. Savage, Eric Stice Jan 2021

Much Ado About Missingness: A Demonstration Of Full Information Maximum Likelihood Estimation To Address Missingness In Functional Magnetic Resonance Imaging Data, Timothy D. Nelson, Rebecca L. Brock, Sonja Yokum, Cara C. Tomaso, Cary R. Savage, Eric Stice

Department of Psychology: Faculty Publications

The current paper leveraged a large multi-study functional magnetic resonance imaging (fMRI) dataset (N = 363) and a generated missingness paradigm to demonstrate different approaches for handling missing fMRI data under a variety of conditions. The performance of full information maximum likelihood (FIML) estimation, both with and without auxiliary variables, and listwise deletion were compared under different conditions of generated missing data volumes (i.e., 20, 35, and 50%). FIML generally performed better than listwise deletion in replicating results from the full dataset, but differences were small in the absence of auxiliary variables that correlated strongly with fMRI task data. However, …


Skills-Based Intervention To Enhance Collaborative Decision-Making: Systematic Adaptation And Open Trial Protocol For Veterans With Psychosis, Emily B.H> Treichler, Borsika A. Rabin, William D.

Skills-Based Intervention To Enhance Collaborative Decision-Making: Systematic Adaptation And Open Trial Protocol For Veterans With Psychosis, Emily B.H> Treichler, Borsika A. Rabin, William D. Spaulding, Michael L. Thomas, Michelle P. Salyers, Eric L. Granholm, Amy N. Cohen, Gregory A. Light

Department of Psychology: Faculty Publications

Background: Collaborative decision-making is an innovative decision-making approach that assigns equal power and responsibility to patients and providers. Most veterans with serious mental illnesses like schizophrenia want a greater role in treatment decisions, but there are no interventions targeted for this population. A skills-based intervention is promising because it is well-aligned with the recovery model, uses similar mechanisms as other evidence-based interventions in this population, and generalizes across decisional contexts while empowering veterans to decide when to initiate collaborative decision-making. Collaborative Decision Skills Training (CDST) was developed in a civilian serious mental illness sample and may fill this gap …


Spring Break Or Heart Break? Extending Valence Bias To Emotional Words, Nicholas R. Harp, Catherine C. Brown, Maital Neta Jan 2021

Spring Break Or Heart Break? Extending Valence Bias To Emotional Words, Nicholas R. Harp, Catherine C. Brown, Maital Neta

Department of Psychology: Faculty Publications

Ambiguous stimuli are useful for assessing emotional bias. For example, surprised faces could convey a positive or negative meaning, and the degree to which an individual interprets these expressions as positive or negative represents their “valence bias.” Currently, the most well- wellvalidated ambiguous stimuli for assessing valence bias include nonverbal signals (faces and scenes), overlooking an inherent ambiguity in verbal signals. This study identified 32 words with dual-valence ambiguity (i.e., relatively high intersubject variability in valence ratings and relatively slow response times) and length-matched clearly valenced words (16 positive, 16 negative). Preregistered analyses demonstrated that the words-based valence bias correlated …

Convolutional Neural Networks Can Decode Eye Movement Data: A Black Box Approach To Predicting Task From Eye Movements, Zachary J. Cole, Karl M. Kuntzelman, Michael D. Dodd, Matthew R. Johnson Jan 2021

Convolutional Neural Networks Can Decode Eye Movement Data: A Black Box Approach To Predicting Task From Eye Movements, Zachary J. Cole, Karl M. Kuntzelman, Michael D. Dodd, Matthew R. Johnson

Department of Psychology: Faculty Publications

Previous attempts to classify task from eye movement data have relied on model architectures designed to emulate theoretically defined cognitive processes and/or data that have been processed into aggregate (e.g., fixations, saccades) or statistical (e.g., fixation density) features. Black box convolutional neural networks (CNNs) are capable of identifying relevant features in raw and minimally processed data and images, but difficulty interpreting these model architectures has contributed to challenges in generalizing lab-trained CNNs to applied contexts. In the current study, a CNN classifier was used to classify task from two eye movement datasets (Exploratory and Confirmatory) in which participants searched, memorized, …


Censored Data Considerations And Analytical Approaches For Salivary Bioscience Data, Hedyeh Ahmadi, Douglas A. Granger, Katrina R. Hamilton, Clancy Blair, Jenna L. Riis Jan 2021

Censored Data Considerations And Analytical Approaches For Salivary Bioscience Data, Hedyeh Ahmadi, Douglas A. Granger, Katrina R. Hamilton, Clancy Blair, Jenna L. Riis

Department of Psychology: Faculty Publications

Left censoring in salivary bioscience data occurs when salivary analyte determinations fall below the lower limit of an assay’s measurement range. Conventional statistical approaches for addressing censored values (i.e., recoding as missing, substituting or extrapolating values) may introduce systematic bias. While specialized censored data statistical approaches (i.e., Maximum Likelihood Estimation, Regression on Ordered Statistics, Kaplan-Meier, and general Tobit regression) are available, these methods are rarely implemented in biobehavioral studies that examine salivary biomeasures, and their application to salivary data analysis may be hindered by their sensitivity to skewed data distributions, outliers, and sample size. This study compares descriptive statistics, correlation …


A New Tool For Equating Lexical Stimuli Across Experimental Conditions, Evan N. Lintz, Phui Cheng Lim, Matthew R. Johnson Jan 2021

A New Tool For Equating Lexical Stimuli Across Experimental Conditions, Evan N. Lintz, Phui Cheng Lim, Matthew R. Johnson

Department of Psychology: Faculty Publications

In cognitive psychology and psycholinguistics, lexical characteristics can drive large effects, which can create confounds when word stimuli are intended to be unrelated to the effect of interest. Thus, it is critical to control for these potential confounds. As an alternative to randomly assigning word bank items to stimulus lists, we present LIBRA (Lexical Item Balancing & Resampling Algorithm), a MATLAB-based toolbox for quickly generating stimulus lists of user-determined length and number that can be closely equated on any number of lexical properties. The toolbox comprises two scripts: a genetic algorithm that performs the inter-list balancing, and a tool for …

Intimate partner violence includes psychological aggression, physical violence, sexual violence, and stalking from a current or former intimate partner. Past research suggests that exposure to intimate partner violence can impact cognitive and psychological functioning, as well as neurological outcomes. These seem to be compounded in those who suffer a brain injury as a result of trauma to the head, neck or body due to physical and/or sexual violence. However, our understanding of the neurobehavioral and neurobiological effects of head trauma in this population is limited due to factors including difficulty in accessing/recruiting participants, heterogeneity of samples, and premorbid and comorbid …
