Differentiating Disclosure And Concealment In Measurement Of Outness For Sexual Minorities: The Nebraska Outness Scale, Peter C. Meidlinger, Debra A. Hope

Department of Psychology: Faculty Publications

Research on lesbian, gay, and bisexual (LGB) individuals has long examined outness, or openness about one’s sexual orientation, as an important predictor of health and well-being. The authors reconceptualized outness as a composite of two related but independent constructs: disclosure and concealment of sexual orientation. This conceptualization guided creation of the Nebraska Outness Scale (NOS), a 10-item measure with a concealment (NOS-C) and disclosure (NOS-D) subscale. The scale and subscales showed good internal reliability, discriminant, convergent, and predictive validity. As hypothesized, concealment showed a stronger relationship to mental health and well-being constructs than disclosure. Disclosure, but not concealment, also differed …

Borderline Personality Disorder And Self-Conscious Emotions In Response To Adult Unwanted Sexual Experiences, Michelle Schoenleber, Kim L. Gratz, Terri Messman-Moore, David Dilillo

Department of Psychology: Faculty Publications

Borderline personality disorder (BPD) is associated with a proneness to unpleasant self-conscious emotions (SCE). Given that BPD is also associated with heightened rates of SCE-eliciting events (including unwanted sexual experiences), research examining the factors influencing SCE in response to these events is needed. This study examined associations between BPD pathology and SCE in response to adult unwanted sexual experiences among 303 community women. Extent of sharing about and perceived personal responsibility for the event were examined as moderators of the association between BPD and current event-related SCE. Both self-reported BPD symptom severity in the full sample and interview-based measures of …

Dimensional Structure Of Dsm-5 Posttraumatic Stress Symptoms: Support For A Hybrid Anhedonia And Externalizing Behaviors Model, Cherie Armour, Jack Tsai, Tory A. Durham, Ruby Charak, Tracey L. Biehn, Jon D. Elhai, Robert H. Pietrzak

Department of Psychology: Faculty Publications

Several revisions to the symptom clusters of posttraumatic stress disorder (PTSD) have been made in the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Central to the focus of this study was the revision of PTSD's tripartite structure in DSM-IV into four symptom clusters in DSM-5. Emerging confirmatory factor analytic (CFA) studies have suggested that DSM-5 PTSD symptoms may be best represented by one of two 6-factor models: (1) an Externalizing Behaviors model characterized by a factor which combines the irritability/anger and self-destructive/reckless behavior items; and (2) an Anhedonia model characterized by items of loss of …

Differential Effects Of Intermittent Versus Continuous Haloperidol Treatment Throughout Adolescence On Haloperidol Sensitization And Social Behavior In Adulthood, Jun Gao, Ming Li

Department of Psychology: Faculty Publications

Animal work on the behavioral effects of antipsychotic treatment suggests that different dosing regimens could affect drug sensitivity differently, with an intermittent treatment regimen tending to cause a sensitization effect, while a continuous treatment causing a tolerance. In this study, we explored how haloperidol (HAL) sensitization induced throughout adolescence and tested in adulthood was differentially impacted by these two dosing regimens in the conditioned avoidance response (CAR) test.We also examined howthese two dosing regiments affected social interaction and social memory in adulthood. Male adolescent Sprague-Dawley rats were treated with HAL via either osmotic minipump(HAL-0.25 CONT; 0.25mgkg⁻¹ day⁻¹, …

The Clinical Psychology Training Program At The University Of Nebraska–Lincoln, David J. Hansen, Timothy D. Nelson, David Dilillo, Debra A. Hope

Department of Psychology: Faculty Publications

The Clinical Psychology Training Program (CPTP) at the University of Nebraska–Lincoln (UNL) has been continuously accredited by the American Psychological Association (APA) since 1948, the first year any programs were accredited. The CPTP’s history and approach to training through the years have been described in numerous articles (DiLillo & McChargue, 2007; Hargrove, 1991; Hargrove & Howe, 1981; Hargrove & Spaulding, 1988; Hope, Hansen, & Cole, 1994; Howe, 1974; Howe & Neimeyer, 1979; Jones & Levine, 1963; Rivers & Cole, 1976). Our program was historically described as a “Community-Clinical” psychology training program, and this focus on understanding and enhancing well-being at …

Botulinum Toxin-Induced Facial Muscle Paralysis Affects Amygdala Responses To The Perception Of Emotional Expressions: Preliminary Findings From An A-B-A Design, M. Justin Kim, Maital Neta, F. Caroline Davis, Erika J. Ruberry, Diana Dinescu, Tood F. Heatherton, Mitchell A. Scotland, Paul J. Whalen

Department of Psychology: Faculty Publications

Background: It has long been suggested that feedback signals from facial muscles influence emotional experience. The recent surge in use of botulinum toxin (BTX) to induce temporary muscle paralysis offers a unique opportunity to directly test this “facial feedback hypothesis.” Previous research shows that the lack of facial muscle feedback due to BTX-induced paralysis influences subjective reports of emotional experience, as well as brain activity associated with the imitation of emotional facial expressions. However, it remains to be seen whether facial muscle paralysis affects brain activity, especially the amygdala, which is known to be responsive to the perception of …

Asenapine Sensitization From Adolescence To Adulthood And Its Potential Molecular Basis, Qing Shu, Rongyin Qin, Yingzhu Chen, Gang Hu, Ming Li

Department of Psychology: Faculty Publications

Asenapine is a new antipsychotic drug that induces a long-lasting behavioral sensitization in adult rats. The present study investigated the developmental impacts of adolescent asenapine treatment on drug sensitivity and on 3 proteins implicated in the action of antipsychotic drugs (i.e. Brainderived neurotrophic factor (BDNF), dopamine D₂ receptor, and ΔFosB) in adulthood. Male adolescent Sprague-Dawley rats (postnatal days, P 43-48) were first treated with asenapine (0.05, 0.10 or 0.20 mg/kg, sc) and tested in the conditioned avoidance or PCP (2.0 mg/kg, sc)-induced hyperlocomotion tasks for 5 days. After they became adults (∼P 76), asenapine sensitization was assessed in a …

Effect Of Environmental Cues On Behavioral Efficacy Of Haloperidol, Olanzapine And Clozapine In Rats, Tao Sun, Xinfeng Liu, Ming Li

Department of Psychology: Faculty Publications

Previous studies have reported that context can powerfully modulate the inhibitory effect of an antipsychotic drug on phencyclidine (PCP)-induced hyperlocomotion (a behavioral test used to evaluate putative antipsychotic drugs). The present study investigated the experimental conditions under which environmental stimuli exert their influence through associative conditioning processes. Experiment 1 examined the extent to which prior antipsychotic treatment in the home cages affected a drug’s ability to inhibit PCP-induced hyperlocomotion in a novel motor activity test apparatus. Five days of repeated haloperidol (0.05 mg/kg, sc) and olanzapine (2.0 mg/kg, sc) treatment in the home cages still potentiated their inhibition of PCP-induced …

The Interplay Of Trait Anger, Childhood Physical Abuse, And Alcohol Consumption In Predicting Intimate Partner Aggression, Rosalita C. Maldonado, Laura E. Watkins, David Dilillo

Department of Psychology: Faculty Publications

The current study examined three well-established risk factors for intimate partner aggression (IPA) within Finkel and Eckhardt’s I³ model, including two impellance factors—trait anger and childhood physical abuse history—and the disinhibiting factor of alcohol consumption. Participants were 236 male and female college students in a committed heterosexual dating relationship who completed a battery of self-report measures assessing childhood physical abuse, trait anger, alcohol consumption, and IPA perpetration. Results revealed a significant three-way interaction showing that as the disinhibition factor alcohol consumption increased, the interaction of the two impelling factors, trait anger and childhood physical abuse, became increasingly more positive. …

Evolutionary Pressures On Primate Intertemporal Choice, Jeffrey R. Stevens

Department of Psychology: Faculty Publications

From finding food to choosing mates, animals must make intertemporal choices that involve fitness benefits available at different times. Species vary dramatically in their willingness to wait for delayed rewards. Why does this variation across species exist? An adaptive approach to intertemporal choice suggests that time preferences should reflect the temporal problems faced in a species' environment. Here, I use phylogenetic regression to test whether allometric factors (relating to body size), relative brain size, and social group size predict how long 13 primate species will wait in laboratory intertemporal choice tasks. Controlling for phylogeny, a composite allometric factor that includes …

Antioxidant Gene Therapy Against Neuronal Cell Death, Juliana Navarro-Yepes, Laura Zavala-Flores, Anandhan Annadurai, Fang Wang, Maciej Skotak, Namas Chandra, Ming Li, Aglaia Pappa, Daniel Martinez-Fong, Luz Maria Del Razo, Betzabet Quintanilla-Vega, Rodrigo Franco

Department of Psychology: Faculty Publications

Oxidative stress is a common hallmark of neuronal cell death associated with neurodegenerative disorders such as Alzheimer's disease, Parkinson's disease, as well as brain stroke/ischemia and traumatic brain injury. Increased accumulation of reactive species of both oxygen (ROS) and nitrogen (RNS) has been implicated inmitochondrial dysfunction, energy impairment, alterations in metal homeostasis and accumulation of aggregated proteins observed in neurodegenerative disorders, which lead to the activation/modulation of cell death mechanisms that include apoptotic, necrotic and autophagic pathways. Thus, the design of novel antioxidant strategies to selectively target oxidative stress and redox imbalance might represent important therapeutic approaches against neurological disorders. …

Long-Lasting Sensitization Induced By Repeated Risperidone Treatment In Adolescent Sprague-Dawley Rats: A Possible D2 Receptor Mediated Phenomenon?, Jing Qiao, Jun Gao, Qing Shu, Qinglin Zhang, Gang Hu, Ming Li

Department of Psychology: Faculty Publications

Rationale Risperidone use in children and adolescents for the treatment of various neuropsychiatric disorders (e.g., schizophrenia, autism, disruptive behavior, etc.) has increased substantially in recent decades. However, its long-term effect on the brain and behavioral functions is not well understood. Objective The present study investigated how a short-term risperidone treatment in adolescence impacts antipsychotic response in adulthood in the conditioned avoidance response and phencyclidine (PCP)-induced hyperlocomotion tests. Methods Male adolescent Sprague-Dawley rats (postnatal days [P] 40–44 or 43–48) were first treated with risperidone (0.3, 0.5, or 1.0 mg/kg, subcutaneously (sc)) and tested in the conditioned avoidance or PCP (3.2 mg/kg, …

Repeated Aripiprazole Treatment Causes Dopamine D2 Receptor Up-Regulation And Dopamine Supersensitivity In Young Rats, Fausto A. Varela, Taleen Der-Ghazarian, Ryan J. Lee, Sergios Charntikov, Cynthia A. Crawford, Sanders A. Mcdougall

Department of Psychology: Faculty Publications

Aripiprazole is a second-generation antipsychotic that is increasingly being prescribed to children and adolescents. Despite this trend, little preclinical research has been done on the neural and behavioral actions of aripiprazole during early development. In the present study, young male and female Sprague-Dawley rats were pretreated with vehicle, haloperidol (1 mg/kg), or aripiprazole (10 mg/kg) once daily on postnatal days (PD) 10–20. After one, four, or eight days (i.e., on PD 21, PD 24, or PD 28), amphetamine-induced locomotor activity and stereotypy, as well as dorsal striatal D2 receptor levels, were measured in separate groups of rats. Pretreating young rats …

Intravenous Ghrelin Administration Increases Alcohol Craving In Alcohol-Dependent Heavy Drinkers: A Preliminary Investigation, Lorenzo Leggio, William H. Zywiak, Samuel R. Fricchione, Steven M. Edwards, Suzanne M. De La Monte, Robert M. Swift, George A. Kenna

Department of Psychology: Faculty Publications

Background: There is a need to identify novel pharmacologic targets to treat alcoholism. Animal and human studies suggest a role for ghrelin in the neurobiology of alcohol dependence and craving. Here, we were the first to test the hypothesis that intravenous administration of exogenous ghrelin acutely increases alcohol craving.

Methods: This was a double-blind, placebo-controlled human laboratory proof-of-concept study. Nontreatment-seeking, alcoholdependent, heavy-drinking individuals were randomized to receive intravenous ghrelin 1 mcg/kg, 3 mcg/kg or 0 mcg/kg (placebo), followed by a cue-reactivity procedure, during which participants were exposed to neutral (juice) and alcohol cues. The primary outcome variable was the increase …

Problematic Alcohol Use And Sexual Assault Among Male College Students: The Moderating And Mediating Roles Of Alcohol Outcome Expectancies, Antover P. Tuliao, Dennis E. Mcchargue

Department of Psychology: Faculty Publications

Background and Objectives: Extant research shows a strong relationship between alcohol use problems and sexual aggression. However, less is known about the effect of intermediary factors (eg, alcohol expectations) that may increase the likelihood of and/or explain sexual aggression during alcohol-related incidents. The present study examined alcohol outcome expectancies’ (OE) mediating and/or moderating influence on the relationship between problematic alcohol use severity and sexual aggression among male college students.

Methods and Result: One hundred and forty eight (n = 148) male college students volunteered for the study. Seventyseven males self-reported committing at least one act of sexual aggression in …

Effects Of 5-Hydroxytryptamine 2c Receptor Agonist Mk212 And 2a Receptor Antagonist Mdl100907 On Maternal Behavior In Postpartum Female Rats, Weihai Chen, Qi Zhang, Wenxin Su, Yu Yang, Jing Qiao, Nan Sui, Ming Li

Department of Psychology: Faculty Publications

Maternal behavior in rats is a highly motivated and well-organized social behavior. Given the known roles of serotonin (5-HT) in emotion, motivation, social behavior, and major depression – and its known interaction with dopamine – it is likely that serotonin also plays a crucial role in this behavior. So far, there are surprisingly few studies focusing on 5-HT in maternal behavior, except for maternal aggression. In the present study,we examined the effects of 5-HT_2C receptor agonism and 5-HT_2A receptor antagonism on maternal behavior in postpartum female rats.We hypothesized that activation of 5-HT_2C receptors and blockade of 5-HT …

Hazardous Alcohol Use And Intimate Partner Aggression Among Dating Couples: The Role Of Impulse Control Difficulties, Laura E. Watkins, Rosalita C. Maldonado, David Dilillo

Department of Psychology: Faculty Publications

To date, research identifying moderators of the alcohol–intimate partner aggression (IPA) relation-ship has focused almost exclusively on male‐perpetrated aggression, without accounting for the dy-adic processes of IPA. The current study examined hazardous alcohol use and impulse control diffi-culties as predictors of IPA among a sample of 73 heterosexual dating couples. Both actor and partner effects of these risk factors on physical and psychological aggression were examined. Results indi-cated that impulse control difficulties were an important actor and partner predictor of both physical and psychological aggression. Findings supported the multiple threshold model such that the inter-action between impulse control difficulties and …

Adult Response To Olanzapine Or Clozapine Treatment Is Altered By Adolescent Antipsychotic Exposure: A Preclinical Test In The Phencyclidine Hyperlocomotion Model, Qing Shu, Gang Hu, Ming Li

Department of Psychology: Faculty Publications

This study examined how repeated olanzapine (OLZ) or clozapine (CLZ) treatment in adolescence alters sensitivity to the same drug in adulthood in the phencyclidine (PCP) hyperlocomotion model. Male adolescent Sprague-Dawley rats (postnatal day (P) 44–48) were first treated with OLZ (1.0 or 2.0 mg/kg, subcutaneously (sc)) or CLZ (10.0 or 20.0 mg/kg, sc) and tested in the PCP (3.2 mg/kg, sc)-induced hyperlocomotion model for five consecutive days. Then a challenge test with OLZ (0.5 mg/kg) or CLZ (5.0 mg/kg) was administered either during adolescence (~P 51) or after the rats matured into adults (~P 76 and 91). During adolescence, repeated …

The Temporal Dynamics Of Visual Working Memory Guidance Of Selective Attention, Jinfeng Tan, Yuanfang Zhao, Shanshan Wu, Lijun Wang, Glenn Hitchman, Xia Tian, Ming Li, Li Hu, Antao Chen

Department of Psychology: Faculty Publications

The biased competition model proposes that there is top-down directing of attention to a stimulus matching the contents of working memory (WM), even when the maintenance of a WM representation is detrimental to target relevant performance. Despite many studies elucidating that spatial WM guidance can be present early in the visual processing system, whether visual WM guidance also influences perceptual selection remains poorly understood. Here, we investigated the electrophysiological correlates of early guidance of attention by WM in humans. Participants were required to perform a visual search task while concurrently maintaining object representations in their visual WM. Behavioral results showed …

Moral Intuitions About Fault, Parenting, And Child Custody After Divorce, Ashley M. Votruba, Sanford L. Braver, Ira Mark Ellman, William V. Fabricius

Department of Psychology: Faculty Publications

Allocations of child custody postdivorce are currently determined according to the best interest standard; that is, what is best for the child. Decisions about what is best for a child necessarily reflect cultural norms, at least in part. It is therefore useful as well as interesting to ask whether current understandings of the best interest standard align with moral intuitions of lay citizens asked to take the role of judge in hypothetical cases. Do factors such as whether 1 parent had an extramarital affair influence how respondents would award custody? In the current studies, a representative sample of citizens awaiting …

Disputed Paraphilia Diagnoses And Legal Decision Making: A Case Law Survey Of Paraphilia Nos, Nonconsent, Christopher M. King, Lindsey E. Wylie, Eve M. Brank, Kirk Heilbrun

Department of Psychology: Faculty Publications

Paraphilia diagnoses applied in forensic settings are an ongoing subject of debate among psycholegal professionals and scholars. Disagreements pertain to both means-related issues having to do with issues of diagnostic reliability and validity, and ends-related issues regarding the consequences inherent to the legal contexts in which the diagnoses arise. To provide a fresh outlook on some of the issues, the present study entailed a systematic survey of U.S. case law to investigate the history, extent, and nature of forensic uses of a controversial paraphilia diagnosis, paraphilia not otherwise specified, nonconsent. Descriptive analyses revealed that use of the diagnosis, which occurred …

Songs You Know By Heart: Alcohol, Promiscuous Sex, Drugs, And Escape In Jimmy Buffett’S Music, Eve M. Brank, Kathleen A. Fox, Victoria Kaspar

Department of Psychology: Faculty Publications

Some researchers argue singer-songwriter Jimmy Buffett’s lyrics focus on alcohol, promiscuous sex, and drugs, while others say Buffett’s music has changed since he sold out to corporate sponsorship. Results from a systematic coding of all 386 of his songs released since 1969 indicate Buffett’s music is more about escape and irony than deviant behaviors. Furthermore, lyric themes remain largely unaltered even through an increase in his popularity and corporate sponsorship.

Child Advocacy Center Based Group Treatment For Child Sexual Abuse, Grace S. Hubel, Christopher Campbell, Tiffany West, Samantha Friedenberg, Alayna Schreier, Mary Fran Flood, David J. Hansen

Department of Psychology: Faculty Publications

The present study examines initial symptom presentation among participants, outcomes, and social validity for a group treatment for child sexual abuse delivered at a child advocacy center. Participants were 97 children and their nonoffending caregivers who were referred to Project SAFE (Sexual Abuse Family Education), a standardized, 12-week cognitive-behavioral group treatment for families who have experienced child sexual abuse. Sixty-four percent of children presented with clinically significant symptoms on at least one measure with established clinical cutoffs. Caregivers of children who presented with clinically significant symptoms reported more distress about their competence as caregivers. Children who presented as subclinical were …

Heterogeneous Symptom Patterns Of Sexually Abused Children In Treatment: Understanding The Complexity Of The Problem, Genelle K. Sawyer, David J. Hansen

Department of Psychology: Faculty Publications

A major challenge for clinicians and researchers is the heterogeneity of the severity and type of symptoms presented by sexually abused youth, including those who are subclinical on traditional clinical measures but still present to treatment. Most research continues to treat sexually abused youth as a single population and has not assessed the outcomes or symptom trajectories of various groups of sexually abused youth. Participants included 107 sexually abused children and their nonoffending parents presenting to a cognitive-behavioral group treatment. A cluster analysis using child and parent-report measures revealed four profiles, including Subclinical, Highly Distressed, Problem Behaviors, and Self-Reported Distress …

Child Maltreatment And Adult Criminal Behavior: Does Criminal Thinking Explain The Association?, Lorraine E. Cuadra, Anna E. Jaffe, Renu Thomas, David Dilillo

Department of Psychology: Faculty Publications

Criminal thinking styles were examined as mediational links between different forms of child maltreatment (i.e., sexual abuse, physical abuse, and physical neglect) and adult criminal behaviors in 338 recently adjudicated men. Analyses revealed positive associations between child sexual abuse and sexual offenses as an adult, and between child physical abuse/neglect and endorsing proactive and reactive criminal thinking styles. Mediation analyses showed that associations between overall maltreatment history and adult criminal behaviors were accounted for by general criminal thinking styles and both proactive and reactive criminal thinking. These findings suggest a potential psychological pathway to criminal behavior associated with child maltreatment. …

Childhood Exposure To Family Violence And Adult Trauma Symptoms: The Importance Of Social Support From A Spouse, Sarah E. Evans, Anne L. Steel, Laura E. Watkins, David Dilillo

Department of Psychology: Faculty Publications

This study examines the roles of positive and negative social support from a spouse as potential moderators of associations between experiences of physical abuse and exposure to intimate partner violence (IPV) as a child and adult trauma symptoms. We hypothesized that positive social support received from a spouse would have a buffering effect on trauma symptoms whereas negative social support from a spouse would have a potentiating effect. Participants were 193 newlywed couples (total N = 386) randomly recruited from a marriage license database. Participants completed self-report questionnaires measuring the nature and severity of child maltreatment and trauma symptoms, and …

The Longitudinal Impact Of Intimate Partner Aggression And Relationship Status On Women’S Physical Health And Depression Symptoms, Laura E. Watkins, Anna E. Jaffe, Lesa Hoffman, Kim L. Gratz, Terri L. Messman-Moore, David Dilillo

Department of Psychology: Faculty Publications

Intimate partner aggression (IPA) has many detrimental effects, particularly among young women. The present study examined the longitudinal effects of IPA victimization and relationship status on physical health and depression symptoms in a sample of 375 community women between the ages of 18 and 25 years. All variables were assessed at 4 occasions over a 12-month period (i.e., 1 assess-ment every 4 months). Multilevel modeling revealed that IPA victimization had both between- and within-person effects on women’s health outcomes, and relationship status had within-person effects when women did not report current IPA. Although IPA was generally related to greater physical …

Interoception And Learning: Import To Understanding And Treating Diseases And Psychopathologies, Rick A. Bevins, Joyce Besheer

Department of Psychology: Faculty Publications

Chemotherapeutic agents nauseate cancer patients. Some individuals with schizophrenia hear voices. Chronic pain can be reduced by analgesics. Nausea, voices, and pain are examples of internal (interoceptive) stimuli closely linked with a disease and/or its treatment. There is evidence that the perception and, hence, role of these internal stimuli can be modified by one’s learning history. There is also increased awareness by researchers and practitioners of the potential import of learning involving internal states to some diseases and psychopathologies. Unfortunately, the science, theory, and practice appear to be trailing behind awareness. In this mini-review, we describe two examples: smoking and …

Decoding Individual Natural Scene Representations During Perception And Imagery, Matthew R. Johnson, Marcia K. Johnson

Department of Psychology: Faculty Publications

We used a multi-voxel classification analysis of functional magnetic resonance imaging (fMRI) data to determine to what extent item-specific information about complex natural scenes is represented in several category-selective areas of human extrastriate visual cortex during visual perception and visual mental imagery. Participants in the scanner either viewed or were instructed to visualize previously memorized natural scene exemplars, and the neuroimaging data were subsequently subjected to a multi-voxel pattern analysis (MVPA) using a support vector machine (SVM) classifier. We found that item-specific information was represented in multiple scene-selective areas: the occipital place area (OPA), parahippocampal place area (PPA), retrosplenial cortex …

Mental Health Help Seeking Among Filipinos: A Review Of The Literature, Antover P. Tuliao

Department of Psychology: Faculty Publications

This study aims to provide a review of potential barriers to seeking mental health services among Filipinos. Research on help-seeking behavior s among Filipinos living in the Philippines and other countries (e.g., US, Canada, and Australia) suggest that mental health services in the Philippines are inaccessible and monetarily prohibitive, and beliefs about the aetiology and nature of mental illness are inconsistent with the medical model. Other cultural variables such as shame, stigma, and collectivist beliefs also discourage Filipinos from seeking help from mental health professionals. Furthermore, these variables could account for the preference for folk healers and lay networks in …
