Identifying Youth At Risk For Problematic Absenteeism Using Nonparametric Modeling: The Impact Of Youth Psychopathology And Family Environment Risk Factors, Mirae Fornander Dec 2018

Identifying Youth At Risk For Problematic Absenteeism Using Nonparametric Modeling: The Impact Of Youth Psychopathology And Family Environment Risk Factors, Mirae Fornander

UNLV Theses, Dissertations, Professional Papers, and Capstones

The best cutoff to differentiate problematic school absenteeism from nonproblematic school absenteeism has yet to be identified in the literature (Lyon & Cotler, 2007). Contemporary classification systems, including Multi-Tiered Systems of Support (MTSS), depend upon cutoffs to clearly define the various tiers (Jimerson, Burns, & VanDerHeyden, 2016). The current study aimed to inform the MTSS approach while also contributing to early identification, assessment, and intervention methods for those youth and families at the highest risk of problematic school absenteeism and its negative consequences. The current study identified subgroups of youth at the highest risk of problematic absenteeism, defined as equal …


Confirmatory Factor Analysis Of Oppositional Defiant Disorder Within Clinically Referred Youth, Breanna Garcia Dec 2018

Confirmatory Factor Analysis Of Oppositional Defiant Disorder Within Clinically Referred Youth, Breanna Garcia

UNLV Theses, Dissertations, Professional Papers, and Capstones

Each new edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5; APA, 2013) has been met with substantial criticism. Particularly, in DSM-5, two disorders were defined by very similar criteria. Oppositional defiant disorder (ODD) was defined as consisting of three dimensions - irritability, noncompliance, and spiteful/vindictive. Additionally, ODD has duration criteria that indicate its symptoms must be present for at least 6 months suggesting the presence of chronic irritability. DSM-5 also included disruptive mood dysregulation disorder (DMDD) as a disorder marked by the presence of chronic irritability in childhood and adolescence. The question of whether chronic irritability (i.e., …


The Influence Of Opponent Strategy And Psychopathic Traits On Point Gains And Cooperation In The Iterated Prisoner’S Dilemma, Mary Baggio Dec 2018

The Influence Of Opponent Strategy And Psychopathic Traits On Point Gains And Cooperation In The Iterated Prisoner’S Dilemma, Mary Baggio

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Prisoner’s Dilemma game is a paradigm used to model and measure social cooperation. Uncooperative behavior may be one manifestation of the unstable interpersonal functioning in psychopathy. I investigated the effect of opponent strategy as well as psychopathic traits of fearless dominance (FD) and impulsive antisociality (IA) on cooperation rates and total and competitive point gains in a sample of 177 undergraduates playing long, finitely iterated Prisoner’s Dilemma games against computerized opponents who varied in their interpersonal styles from very harsh to very lenient. I analyzed rates of cooperation during each game, participants’ total points gained, and the difference in …


Development Of The Emotional Verbal Learning Test - Spanish (Evlt-S), Davor Nicolas Zink Dec 2018

Development Of The Emotional Verbal Learning Test - Spanish (Evlt-S), Davor Nicolas Zink

UNLV Theses, Dissertations, Professional Papers, and Capstones

Emotional disturbances are common features of clinical disorders and are often present in individuals who have neurodevelopmental or acquired brain disorders. The Hispanic population is the largest and fastest growing ethnic minority group in the United States (U.S.) and by 2050 is projected to be the largest. However, few instruments are available to evaluate emotional functioning in individuals who speak Spanish. Fewer still are available to assess cognitive disturbances resulting from brain dysfunction that impact emotion processing. Normal processing of emotion is critical for social functioning. In recent years it has become apparent that cognitive abilities specialized to process social …


Malingering Undetected Successfully: Does Extrinsic Motivation And Coaching Have A Significant Impact?, Jennifer Golanics Aug 2018

Malingering Undetected Successfully: Does Extrinsic Motivation And Coaching Have A Significant Impact?, Jennifer Golanics

UNLV Theses, Dissertations, Professional Papers, and Capstones

The present study examined the effectiveness of a Mild Traumatic Brain Injury (mTBI) coaching (i.e., providing information about mTBI symptoms) and motivational incentive (i.e., a $50 gift card lottery) on the Automated Neuropsychological Assessment Metrics (ANAM) test performance. The sample included a total of 162 undergraduate and graduate students enrolled in an introductory educational psychology course. Participants were randomly assigned to one of six conditions: coached plus warning instruction and motivation incentive, coached instruction and motivation incentive, uncoached instruction and motivation incentive, coached plus warning instruction and no motivation incentive, coached instruction and no motivation incentive, and uncoached instruction and …


An Examination Of Student-Athlete Stress And Risky Alcohol Use, Travis Albert Loughran Aug 2018

An Examination Of Student-Athlete Stress And Risky Alcohol Use, Travis Albert Loughran

UNLV Theses, Dissertations, Professional Papers, and Capstones

Student-athletes are a sub-population of college students that are likely to engage in binge drinking behavior and experience the negative consequences associated with alcohol use (Barry, Howell, Riplinger, & Piazza-Gardner, 2015; Nelson & Wechsler, 2001). In addition, participating in intercollegiate athletics comes with unique stressors not faced by non-athlete students, such as balancing academic responsibilities with athletic obligations, managing the strain associated with playing competitive sport, and navigating complex interpersonal relationships with coaches, teammates, and peers (Parham, 1993; Watson, 2002). However, there appears to be little research examining the relationship between alcohol risk and the specific stressors associated with being …


Examination Of A Screening Tool For Athletes’ Mental Health And Its Direct Implications To Sport Training And Competition, Jesse Scott Aug 2018

Examination Of A Screening Tool For Athletes’ Mental Health And Its Direct Implications To Sport Training And Competition, Jesse Scott

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Sport Interference Checklist (SIC) is a psychometrically validated instrument designed to assess how often cognitive and behavioral factors interfere with athletes performance during training and/or competition as well as the extent to which athletes are interested in pursuing sport psychology to address these problems. The success of this scale inspired an interest in developing new items that assess the influence of specific mental health concerns on sport performance using the SIC format. The Sport Interference Checklist’s Sport Specific Screen for Mental Health (SIC-SSSMH) was empirically developed using 259 athletes to assist in the identification of mental health problems explicitly …


The Structure Of Psychopathology And Its Relationship To Personality And Eeg, Vincent Rozalski Aug 2018

The Structure Of Psychopathology And Its Relationship To Personality And Eeg, Vincent Rozalski

UNLV Theses, Dissertations, Professional Papers, and Capstones

The factor structure of psychopathology has been debated in the literature, with studies showing support for several models, including one-, two-, and three-factor solutions. The factor structures often vary as a function of what symptoms and diagnoses are included, and when a wide array of diagnoses are present, a three-factor solution is often found. Personality has been shown to be related to psychopathology and its higher order structures, but there is little research regarding neurobiological associations that take into account the factor structure of psychopathology along with personality. This dissertation examined the factor structure of a wide range of psychopathology, …


Evaluation Of A Brief “Surf The Urge” Intervention, Kimberly N. Schubert Aug 2018

Evaluation Of A Brief “Surf The Urge” Intervention, Kimberly N. Schubert

UNLV Theses, Dissertations, Professional Papers, and Capstones

Previous research has demonstrated that mindfulness interventions can assist in increasing an individual’s wellbeing. This includes improving an individual’s mental health and decreasing urge-related behaviors (e.g., substance use, deliberate self-harm, aggression). Nevertheless, there is limited research on the efficaciousness of mindfulness interventions with adolescents. These interventions are also time consuming and expensive. The purpose of this study is to examine the effectiveness of a brief (i.e., 10 to 20 minutes) mindfulness intervention to assist adolescents in reducing their urge-related behaviors. I hypothesized that the brief intervention would reduce participants’ urge-related behaviors but not urge feelings. The intervention was also predicted …
