Examination of a Bi-Directional Relationship between Urgency and Alcohol Use (open access)

Examination of a Bi-Directional Relationship between Urgency and Alcohol Use

The proposed study examined whether negative urgency and positive urgency are dynamic traits that hold bi-directional relationships with binge and prolonged alcohol use across time. Individuals between the ages of 18-30 were recruited from Amazon Mechanical Turk (MTurk; n = 179) and university student (n = 66) pools. Participants completed three batteries of self-report assessments approximately 30 days apart, each containing measures assessing negative and positive urgency, as well as drinking frequency and binge behavior during the prior month. Latent variable cross-lagged panel models examined the effects of alcohol use from the previous month on negative and positive urgency while controlling for concurrent and autoregressive effects. Results of the current study indicated that for the full sample, there was not an effect for the influence of binge/prolonged drinking on either negative or positive urgency during the subsequent month. However, when examined separately by sample (Turkers vs. university) and gender (male vs. female), significant effects were found more for individuals who were Turkers, male, and/or heavy drinkers, suggesting that increases in positive and negative urgency at Time 2 could be partially explained by variance in drinking patterns at Time 1 for these individuals. However, these relationships were not replicated again between …

Consistency, Consolidation, and Cognition in Autobiographical Memories: a Flashbulb Memory Approach (open access)

Consistency, Consolidation, and Cognition in Autobiographical Memories: a Flashbulb Memory Approach

Flashbulb memories are highly vivid and long-lasting memories for events that are emotionally significant and personally important. These memories are held in very high confidence in accuracy over an extended period. In particular, individuals believe that they can remember the personal details surrounding the event such as where they were and what they were doing at the time the event occurred. Evidence from research, however, indicates that this may not be the case. The study of flashbulb memories has typically been confined to negative events such as September 11, 2001. In the current study, we employ the methods of Talarico and Rubin (2003) to investigate flashbulb memory formation to a positive event. The event is the assassination of Osama bin Laden, which resonated as a highly positive event for many Americans evidenced by the thousands of people flooding the streets of Washington, D.C. and New York City to celebrate. We examined various memory properties over a one-year period, including vividness, rehearsal, belief in accuracy, and consistency. Results confirm the formation of flashbulb memories to the assassination event, but results did not support many of the proposed hypotheses. Some differences were found for different testing groups (i.e., immediate versus one week …

Mock Juror Effects of Blame and Conviction in Rape Cases: Do Attitudes, Beliefs, and Contact with Homosexuals Matter? (open access)

Mock Juror Effects of Blame and Conviction in Rape Cases: Do Attitudes, Beliefs, and Contact with Homosexuals Matter?

The current case involves a female rape victim. Research has shown the level of victim blaming can be elevated if the victim is a lesbian woman compared to a heterosexual woman. Mock jurors’ responses to personality trait questionnaires (e.g., Belief in a Just World, Attitudes Toward Women, Attitudes Toward Lesbians) and amount of contact they have with homosexual people were employed as predictors of how they would decide victim blaming and perpetrator guilt. Personality trait findings were not good predictors; however, greater contact with homosexuals did decrease negative attitudes toward lesbian victims. Limitations and implications for future research are addressed.

An Examination of a Framework for Posttraumatic Stress Disorder Correlates: Exploring the Roles of Narrative Centrality and Negative Affectivity (open access)

An Examination of a Framework for Posttraumatic Stress Disorder Correlates: Exploring the Roles of Narrative Centrality and Negative Affectivity

Recent estimates suggest that a large percentage of the population experiences some type of traumatic event over the course of the lifetime, but a relatively small proportion of individuals develop severe, long-lasting problems (e.g., posttraumatic stress disorder; PTSD). One major goal for trauma researchers is to understand what factors contribute to these differential outcomes, and much of this research has examined correlates of posttraumatic stress disorder (PTSD) symptom severity. An important next step in this line of research is the development of conceptual frameworks to foster a deeper understanding of the relationships among these diverse predictors of PTSD and their predictive power in relation to each other. A framework proposed by Rubin, Boals, and Hoyle centers on the influence of narrative centrality (construal of a traumatic experience as central to one's identity and to the life story) and negative affectivity (the tendency to experience negative emotion and to interpret situations and experiences in a negative light), suggesting many variables may correlate with PTSD symptoms via shared variance with these two factors. With a sample of 477 participants recruited from Amazon Mechanical Turk, this dissertation project extended the work of Rubin and colleagues by a) utilizing structural equation modeling techniques to …

Modeling Marijuana Use Willingness and Problems as a Function of Social Rejection and Social Anxiety

Access: Use of this item is restricted to the UNT Community
Marijuana is the second most commonly used substance in the US. A growing literature suggests that socially anxious individuals use marijuana to manage their symptoms in social situations, which may explain why they are also more likely to experience problems. Unfortunately, the majority of the literature is based on research conducted with adult samples or the co-occurrence of diagnoses in adolescent samples. The proposed study sought to test the link between social anxiety (SA) and proxies for ‘real-time' marijuana use behaviors (i.e., use willingness) as well as use-related problems among adolescents. Participants were 69 adolescents (15-17; 55% female) recruited from the community reporting any lifetime marijuana use. Participants were randomly assigned to a novel social rejection or neutral laboratory task and completed measures of SA, marijuana use frequency, and related problems. Consistent with adult findings, main effects of SA and experimental condition on marijuana use willingness were expected to be qualified by an interaction in which the greatest marijuana use willingness would occur among high SA youth post-rejection (H1), SA would be positively related to marijuana use problems (H2), and among adolescents in the rejection condition, marijuana use willingness would be positively correlated with use problems (H3). Only H2 was …

Postoperative Neuropsychological Outcomes in Pediatric Patients Undergoing Temporal Lobe Epilepsy Surgery (open access)

Postoperative Neuropsychological Outcomes in Pediatric Patients Undergoing Temporal Lobe Epilepsy Surgery

The purpose of this study was to investigate the neuropsychological outcomes of pediatric subjects undergoing temporal lobe surgery, and then compare the outcomes between subjects in the iMRI and the standard operating suites. This study involved 77 children ages one to 21 years (M = 11.98) at time of surgery for intractable epilepsy. Forty-seven returned for repeat neuropsychological assessment. At baseline, subjects with early onset of epilepsy (≤ 7 years) scored worse on a measure of attention (p = .02), FSIQ (p < .01), perceptual reasoning (p < .01), and processing speed (p = .06). At one-year follow-up, interactions were observed for the response style domain of the attention measure (p = .03), FSIQ (p = .06) and working memory (p = .08). Follow-up at one year, for the group as a whole, revealed decline in verbal memory (p = .04) and reading comprehension (p = .02); and improvement for word reading (p = .05). No significant differences were observed between the iMRI and standard operating suite. Though, hemisphere, duration of epilepsy, preoperative seizure frequency, lesional disease, seizure type, presence of epileptogenic focus, and number of lobes involved accounted for variance in neuropsychological outcomes. These results provide further support for …

Fatigue and Inhibitory Control: A Test of Key Implications of an Emerging Analysis of Behavioral Restraint Intensity (open access)

Fatigue and Inhibitory Control: A Test of Key Implications of an Emerging Analysis of Behavioral Restraint Intensity

Agtarap, Wright, Mlynski, Hammad, and Blackledge took an initial step in providing support for the predictive validity of a new conceptual analysis concerned with behavioral restraint - defined as active resistance against a behavioral impulse or urge. The current study was designed to partially replicate and extend findings from their study, employing a common film clip protocol and a procedure for inducing low- and high levels of fatigue. Analyses indicated that key cardiovascular (CV) responses rose with the evocativeness of the film clip among low fatigue participants but fell with the evocativeness of the film clip among high fatigue participants. This is consistent with the prediction that high fatigue participants would put forth more restrain intensity than low fatigue participants when confronted with the less evocative clip, but less restraint intensity than low fatigue participants when confronted with the more evocative clip. Behavioral restraint performance - quantified as duration of facial non-neutrality - was also consistent with predictions, being impaired by fatigue under high- but not low evocativeness conditions. Findings support the broad theoretical suggestion that fatigue influence on behavioral restraint is multifaceted, dependent on the perceived magnitude of the impulse or urge experienced and the importance of resisting it.

When the Levee Breaks: An SEM Approach to Understanding the Narrative and the Anxiety-Buffer Disruption on PTSD Symptoms (open access)

When the Levee Breaks: An SEM Approach to Understanding the Narrative and the Anxiety-Buffer Disruption on PTSD Symptoms

The purpose of the present study was to assess if combining the two frameworks would account for more variance in PTSS than could be accounted for using the frameworks separately. An online community sample from Amazon.com's Mechanical Turk (N = 437), who reported experiencing a prior traumatic event, completed measures that reflected the constructs of narrative centrality, negative affectivity, and death concerns, along with a measure of PTSS. PTSS was regressed on the latent variables of death concerns, narrative centrality, and negative affectivity, along with the latent variable interactions between narrative centrality*death concerns and narrative centrality*negative affectivity. Death concerns was not be predictive of PTSS, whereas narrative centrality and negative affectivity were found to uniquely and interactively account for 77% of the variance in PTSS. Death concerns was found to be a separate construct from negative affectivity. The implications of these findings for the two frameworks are discussed along with future directions. By considering aspects of narrative centrality and negative affectivity, substantial portions of PTSS can be accounted for.

Is Mind Wandering the Mechanism Responsible for Life Stress Induced Impairments in Working Memory Capacity? (open access)

Is Mind Wandering the Mechanism Responsible for Life Stress Induced Impairments in Working Memory Capacity?

The relationship between life stress and working memory capacity (WMC) has been documented in college students and older adults. It has been proposed that intrusive thoughts about life stress are the mechanism responsible for the impairments seen in WMC. To examine the mechanism responsible for these impairments the current study attempted to induce intrusive thoughts about personal events. The current study allowed for a test of predictions made by two theories of mind wandering regarding the impact of these intrusive thoughts on WMC task performance. One hundred fifty undergraduates were assigned to a control group, positive event group, or negative event group. Participants in the positive and negative event groups completed a short emotional disclosure about an imagined future positive or negative event, respectively, to induce positive or negative intrusive thoughts. WMC measures were completed prior to and following the emotional writing. Results indicated a significant relationship between WMC and mind wandering, however the writing manipulation did not result in any consistent changes in intrusive thoughts or WMC. The results suggest a causal relationship between WMC and mind wandering. The emotional valence of the intrusive thought altered the impact on WMC. No relationship was seen between the measures of stress …

Devaluing Stigma in the Context of Forgiveness, Coping and Adaptation: a Structural Regression Model of Reappraisal (open access)

Devaluing Stigma in the Context of Forgiveness, Coping and Adaptation: a Structural Regression Model of Reappraisal

The 2010 National HIV/AIDS Strategy outlined three important goals for managing the current HIV pandemic in the U.S.: (1) reduce the number of people who become infected with HIV; (2) improve access to health care and health-related outcomes for people living with HIV/AIDS (PLH/A); and (3) reduce HIV-related health disparities. Each of these goals tacitly depends upon reducing HIV-related stigma, and this study examined how HIV+ individuals evaluate coping efforts to overcome stigma’s impact on quality of life (QOL). a structural regression model was developed to instantiate the reappraisal process described by Lazarus and Folkman’s transactional theory of stress and coping, and this model indicated that maladaptive coping fully mediated the relationship between dispositional forgiveness and perceived stigma, which supports the prediction that coping efficacy is related to stress reduction. Additionally, maladaptive coping fully mediated the relationship between dispositional forgiveness and QOL, supporting the contention that forgiveness is a critical aspect to the evaluative process that influences how PLH/A cope with stigma. Lastly, the model showed that when PLH/A engaged in maladaptive coping to mitigate stress-related stigma, these individuals experienced increased stigmatization and reported significantly lower levels of health-related QOL. in contrast, PLH/A that reported higher levels of dispositional forgiveness …

Terror Management Theory and Body Image (open access)

Terror Management Theory and Body Image

Research has not explicitly examined the link between key components of terror management theory (TMT) and body image without the use of mortality salience. This project explored the link between cultural worldview, self-esteem, body image, and death anxiety. Multiple measures were used to create a structural equation model examining relationships between body image and death anxiety as mediated by body image in the context of TMT. The proposed model did not fit the data. Minor modifications were made to the model keeping within the proposed theoretical perspective. In the modified model the relationships between cultural worldview and death anxiety as mediated by body image were either non-existent or weak. Hierarchical regression analyses did suggest that some aspects of body image indeed did predict some, but not all dimension of death anxiety in this sample of young adults.

Response to Sexual Trauma in Relation to Event Centrality and Objectified View of Self (open access)

Response to Sexual Trauma in Relation to Event Centrality and Objectified View of Self

This study examined the potentially differing emotional consequences of sexual versus non-sexual traumas in both a student and a community residing treatment seeking sample of women. The extent to which a trauma survivor considers the traumatic event central to her identity (CES) was examined as a potential mediator between traumatic events and PTSD. Additionally, the extent to which a women views herself and her body as a sexual object, to be valued based on her appearance and sexual usefulness to others (sexual self-objectification: OBCS), was examined as a potential mediator between traumatic event and event centrality. Study results showed survivors of sexual assault reported greater CES and PTSD symptoms (PCL-S) than non-sexual trauma survivors in the student population. Mediation results showed sexual self-objectification (OBCS-Shame) significantly mediated the relationship between trauma type and CES, and CES significantly mediated the relationship between type of trauma and PTSD symptoms in the student population only. Data from the community sample did not support these conclusions as women from this sample reported higher PCL-S, CES, and OBCS-Shame scores across categories of trauma.
