A Controlled Examination Of Motivational Strategies: Reviewing Positive Consequences For Goal Achievement, Negative Consequences For Undesired Behavior, And A Relaxation Exercise, Yulia Gavrilova

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction: Motivation is an integral part of human life and one of the most fundamental aspects of behavior change. Of interest to the present study are two motivational approaches, Negative Consequences Review (NCR) and Positive Consequences Review (PCR). NCR is an intervention component originally designed as part of Family Behavior Therapy (FBT) to motivate individuals with their goals through a discussion of negative consequences associated with undesired behaviors. PCR was developed as an auxiliary component of FBT to inspire individuals’ motivation to achieve their goals through a discussion about positive consequences of reaching goals. Purpose: The purpose of this study …

Mate Preferences Among Single Mothers, Carol Yvette Franco

UNLV Theses, Dissertations, Professional Papers, and Capstones

As individuals become parents, they shift time and energy towards parenting to ensure the survival and wellbeing of their offspring. However, it is not uncommon for a romantic partnership between parents to dissolve, which may lead a single mother to pursue a new partner in the future. But how does having a dependent child influence whom she will choose for her new partner? And how will resource availability and assistance from family influence the decisions she makes? A significant amount of research has been conducted on female mate preferences in the United States and elsewhere, yet little is specifically focused …

Temperament And Behavior Factors In A Community Sample Of Youth With Selective Mutism, Rachele Alexandra Diliberto

UNLV Theses, Dissertations, Professional Papers, and Capstones

Children with selective mutism often present as a very diverse population, with both oppositional (APA, 2013; Cohan et al., 2008; Steinhausen & Juzi, 1996), and anxious symptoms (APA, 2013; Kristensen, 2000; Vecchio & Kearney, 2009) most commonly reported. The first aim of the current study was to validate the presence of previously identified anxious and oppositional behavior factors in a community sample of youth with selective mutism. These factors were previously identified in a clinic sample of youth with selective mutism (Diliberto & Kearney, 2016). The second aim was to examine the association of anxious and oppositional behavior factors with …

Understanding Transitions Of Trust Across Different Business Contexts: An Exploratory Sequential Mixed Methods Study, Sungsik Yoon

UNLV Theses, Dissertations, Professional Papers, and Capstones

Airbnb’s influence has been growing rapidly in the last few years, and hotel operators are beginning to recognize the competitive threat it poses. However, consumers may perceive Airbnb differently than hoteliers. Thus, the current study attempts to explore hotel customers’ perceptions of the sharing economy business (Airbnb). It is important to pay attention to the different business settings of the channels that currently exist in the lodging industry. Moreover, investigating the relationship between trust and perceived risk in this new channel (i.e., Airbnb) is crucial due to the inherent risk of transactions on Airbnb, especially when compared with traditional Business-to-customer. …

Concurrent Mental Health And Sport Performance Enhancement In An Athlete Initiating Behavioral Intervention With No Assessed Pathology: A Case Examination Supporting Optimization, Yulia Gavrilova

UNLV Theses, Dissertations, Professional Papers, and Capstones

Collegiate athletes are often exposed to unique environmental stressors that may negatively impact the way they think, behave, and feel in athletic, academic, and social domains, potentially compromising their performance and mental health when cognitive and behavioral skills are relatively underdeveloped. Behavioral interventions have been shown to enhance cognitive and behavioral skills in persons with assessed mental health deficits in the general population. However, little is known about the relative effects of psychologically-based programs in persons who do not evidence pathology. Along these lines, The Optimum Performance Program in Sports (TOPPS), based on Family Behavior Therapy, was recently developed with …

Examining The Inner Experience Of Four Individuals With Bipolar Disorder Using Descriptive Experience Sampling, Johanah Kang

UNLV Theses, Dissertations, Professional Papers, and Capstones

Bipolar disorder is a lifelong mood disorder with diagnostic criteria that provide a description of expected experiences of individuals diagnosed with BD (e.g., elevated mood, sadness, difficulty concentrating). Despite these criteria, the inner experience of these individuals is largely unknown. Understanding the inner experience of individuals diagnosed with BD may prove essential in understanding and treating BD. The present study examined the inner experience of four individuals diagnosed with BD using the Descriptive Experience Sampling (DES) method (Hurlburt 1990, 1993, 2011). Results revealed all our participants had clear and prevalent experiences of sensory awareness. They also had difficulties apprehending and …

Early Life Stress, Drug Abuse, Exercise Effects On Bdnf And Sex-Influenced Excercise Differences, Karissa Dold

Honors College Theses

In 2011, the U.S. reported 3 million child maltreatment cases, an uncomfortably high but recurring figure each year. Research shows exposure to early life stress (ELS) increases an individual’s susceptibility to substance abuse, specifically of nicotine, alcohol, and cocaine. Increased susceptibility may result from dysregulation of the HPA axis sustaining activation into adulthood after ELS. Hyperactivation of the HPA axis significantly reduces hippocampal BDNF, a neurotrophin involved in neuronal growth and plasticity. Reduced hippocampal BDNF may be a factor in substance abuse vulnerability. Additionally, research shows exercise protects hippocampal BDNF from stress induced down-regulation. To explore these relationships, this study …

Construct And Criterion Validity Of The Rey Auditory Verbal Learning Test-Spanish Version In Adults With Traumatic Brain Injury, Cristobal Neblina

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Rey Auditory Verbal Learning Test (RAVLT) is among the most commonly used English-language neuropsychological tests of verbal learning and memory. Previous research supports the validity and clinical utility of adaptations of the RAVLT into many diverse languages. In the United States, Hispanics represent the largest and fastest-growing ethnic minority group. As the Hispanic populace continues to grow, so does the need for empirically validated Spanish-language neuropsychological measures. In 2002, a Spanish adaptation of the RAVLT was developed in Puerto Rico (Acevedo-Vargas, 2002). However, validation studies have not been undertaken with clinical samples, and little is known regarding its psychometric …

Affect Identification And Interpersonal Skills: An In-Depth Evaluation Of Social Cognition In Schizophrenia, Griffin Pollock Sutton

UNLV Theses, Dissertations, Professional Papers, and Capstones

The presence of deficits in various sub-domains of social cognition has been investigated to a degree in individuals with schizophrenia. Some of the most commonly researched and documented deficits have included impairments in the identification of affect portrayed in faces. Research has indicated that the performance of individuals with schizophrenia on such tasks is generally impaired as compared to normal controls. However, some have questioned the generalizability of such findings to real-world situations, as day-to-day interactions generally necessitate a constant, fluid assessment of the thoughts and feelings of others and are rarely, if ever, limited to still images of others. …

Using Negative Feedback To Guide Behavior: Impairments On The Wisconsin Card Sorting Test Relates To Psychosis, Sally Barney

UNLV Theses, Dissertations, Professional Papers, and Capstones

There is increasing controversy regarding the distinction between schizophrenia and bipolar disorder as separate diagnostic categories because these disorders share many features in common. These and other findings suggest that bipolar disorder and schizophrenia may be better conceptualized along a continuum or within more homogeneous subsets of affective, psychotic, and mixed symptomatology.

Dopamine dysregulation has been found in schizophrenia and bipolar disorder, particularly those that experience psychosis during the acute phases of their bipolar illness. Dopamine has been found to play a role in reward and reward learning. Recently, research has found that individuals with schizophrenia experience deficits in reward …

Descriptive Experience Sampling Interactive Multi-Media Training Tool For Subjunctification And Illustrative Interviews, Stacy Lynne Reger

UNLV Theses, Dissertations, Professional Papers, and Capstones

Modern experience sampling methods attempt to understand the phenomenology of inner experience through a variety of methods, including questionnaires, diaries, and verbalization of ongoing cognitive processes. The goal of such studies is to minimize potential roadblocks to accessing inner experience, such as retrospective recall, memory failures, and bias. The current project focuses on one such method, Descriptive Experience Sampling (DES). DES is an idiographic, exploratory, and ecologically valid method of studying inner experience. In this method, participants wear a beeper with an earphone that emits a random beep. When the beep sounds, the participant is to write down notes about …

The Hormonal Correlates Of Stress And Posttraumatic Stress Disorder Symptoms In Female Veterans, Meghan Pierce

UNLV Theses, Dissertations, Professional Papers, and Capstones

With the increase of female veterans serving in the military, a better understanding of posttraumatic stress disorder is needed to provide comprehensive treatment. This study examines salivary cortisol in female veterans with PTSD, female veterans without PTSD, civilian females with PTSD and healthy controls. The Posttraumatic Stress and Beck Depression Inventory-II were used to assess posttraumatic stress and depressive symptoms. Saliva samples were collected at bedtime and awakening, as well as in response to the Trier Social Stress Test. Significant results were not found for diurnal cortisol levels [ F (3, 11)= .979, p < .05] or stress cortisol levels (F (3,12) = 1.140, p >.05). …

School Refusal Behavior: The Relationship Between Functions And Symptom Sets, Marisa Charlene Hendron

UNLV Theses, Dissertations, Professional Papers, and Capstones

The current study examined the relationship between functions of school refusal behavior and internalizing and externalizing symptom sets in a community sample of 200 youth and parents recruited from two truancy settings. The first hypothesis was that youth who endorsed refusing school primarily to avoid stimuli that provoke negative affectivity (function 1) would report more symptoms of generalized anxiety and depression. The second hypothesis was that youth who endorsed refusing school primarily to escape from aversive social or evaluative situations (function 2) would report more symptoms of social anxiety. The third hypothesis was that youth who endorsed refusing school primarily …

Officer Involved Shooting: The Emotional Impact And The Effective Coping Strategies, Patrick P. Charoen

UNLV Theses, Dissertations, Professional Papers, and Capstones

The emotional impact of a shooting incident on the individual police officer has been recognized and detailed by both police and mental health professionals (Lippert & Ferrara, 1984). The human cost and financial costs to Police Departments as a result of "post shooting" trauma has sensitized many departments to the need for professional support for officers involved in shootings. Recent survey research has provided information about the percentage of officers who experienced great, moderate, or no emotional impact after being involved in shootings (Stratton, 1982). However, information about the degree to which police departments have responded to this need has …
