Eating Pathology, Supplement Use, And Nutrition Knowledge In Collegiate Athletes, Holly Beth Lapota

UNLV Theses, Dissertations, Professional Papers, and Capstones

Eating pathology (e.g., body dissatisfaction, binge eating, purging, restrictive eating) and substance use (e.g., dietary supplements, legal and illegal drugs) proliferate university settings in the United States. Within university settings, athletes appear to be at particularly high risk for eating pathology and supplement use due to the external pressures to be attractive, the need to perform at optimal levels, and the specific characteristics of sports in which they participate. Furthermore, the degree to which athletes understand what constitutes healthy eating and exercise habits is understudied and may relate to eating pathology and supplement use. To build on existing research, the …

An Empirically-Supported Model Of Posttraumatic Stress Disorder In Maltreated Youth, Adrianna Wechsler

UNLV Theses, Dissertations, Professional Papers, and Capstones

Posttraumatic stress disorder in maltreated youth is a young and burgeoning field. Lemos-Miller and Kearney (2006) were among the first to propose and test a theoretically and empirically-based model of PTSD in maltreated youth. The present study replicated and evaluated the Lemos-Miller and Kearney model within a larger and more diverse sample of maltreated adolescents. First, the Lemos-Miller and Kearney model was tested via structural equation modeling (SEM). Second, the model was evaluated across age, gender, and ethnicity. Third, trauma history, family environment (i.e., cohesion and conflict), dissociation, and trauma-related cognitions were evaluated as potential mediating variables within the model. …

Relationship Competence: Can Trainee Interpersonal Skills Be Measured Reliably And Do They Predict Clinical Effectiveness?, Jacqueline Camp

UNLV Theses, Dissertations, Professional Papers, and Capstones

Traditional evaluation and assessment procedures in professional psychology programs have long been criticized for inadequately attending to the set of interpersonal skills that are important to professional functioning in the field of psychology. The present study was exploratory and focused on examining the reliability and validity of an evaluation tool designed to capture a set of interpersonal skills that are clinically relevant and grounded in the empirical literature on psychotherapy outcome. Toward this end, the Facilitative Interpersonal Skills (FIS) task (Anderson, Patterson, & Weiss, 2006) was administered to a sample of trainees (n = 19) enrolled in a clinical psychology …

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 …

The Influence Of Parent Factors On Child Perfectionism: A Cross-Sectional Study, Lisa Caitlin Cook

UNLV Theses, Dissertations, Professional Papers, and Capstones

Perfectionism is a multidimensional construct that affects adults and children and is associated with psychological problems such as depression, anxiety, and obsessive compulsiveness. Studies regarding risk factors for perfectionism are scarce but extant research and theories suggest parents may be involved in the development of perfectionism in children. The present study included 160 children aged 8-17 years (67 males, 93 females) and their parents. The study examined child perfectionism across five age groups (8-9 years, 10-11 years, 12-13 years, 14-15 years, 16-17 years) as well as relationships between parent and child perfectionism and between parent psychopathology and child perfectionism. Self-oriented …

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 Influence Of Social Contagion And Technology On Epidemic Non-Suicidal Self-Injury, Paul M. Kirsch

Calvert Undergraduate Research Awards

Non-suicidal self-injury (NSSI) is the deliberate damaging of one’s body without the intention of suicide (Nock & Favazza, 2009). NSSI can cause serious medical consequences and is associated with psychological impairment or distress in day-to-day functioning. When this type of pathological behavior occurs in inpatient settings, the behavior has been known to spread from patient to patient (Taiminen, Kallio-Soukainen, Nokso-Koivisto, Kaljonen, & Helenius, 1998). Recent internet-based research has shown that online forums have become a place for people to find social connections based on pathology (Whitlock, Powers, & Eckenrode, 2006). Christakis and Fowler (2009) showed that thoughts, actions, and feelings …

The Relationship Of Ethnicity And Familial Factors In The Expression Of School Refusal Behavior In Clinical And Community Samples, Courtney Marie Haight

UNLV Theses, Dissertations, Professional Papers, and Capstones

Failure to attend school can have a devastating impact on a child’s social, emotional, academic, and later career development. Psychologists, educators, and researchers from other disciplines have produced large bodies of literature regarding problematic absenteeism. This has led to varying terminology, divergent approaches, assessment, and treatment of nonattendance. Additional research on contextual, proximal, and distal variables, such as culture and family, has been encouraged. The present study involved contextual variables related to school refusal behavior and contained a more representative sample of youth with attendance difficulties than previous studies. Contextual variables included youth and parent ethnic identity, family environment, school …

Examining The Experience Of Recent War Veterans Who Report Posttraumatic Stress Disorder, Neda C. Raymond

UNLV Theses, Dissertations, Professional Papers, and Capstones

Posttraumatic stress disorder (PTSD), an anxiety disorder that develops following exposure to a traumatic event, has long been associated with military combat. Despite the well-documented negative effects of PTSD, careful, in-depth accounts of the experience of those suffering from PTSD are rare. The present study employed Descriptive Experience Sampling (DES) to explore the inner experience of seven Operation Iraqi Freedom (OIF) or Operation Enduring Freedom (OEF) veterans with combat-related PTSD. Potential participants completed the PTSD Checklist - Military Version to determine the presence and severity of PTSD symptomatology. Participants who reported significant symptoms of combat-related PTSD participated in DES. A …

Enhancing Therapists' Clinical Judgments Of Client Progress Subsequent To Objective Feedback, Michael M. Haderlie

UNLV Theses, Dissertations, Professional Papers, and Capstones

Although it is intuitive that the judgments made by mental-health clinicians become increasingly accurate as they gain clinical experience, research has demonstrated only minimal effects of experience on clinical judgment. Feedback regarding the accuracy of judgments is widely considered to be an essential component in developing clinical judgment. However, very little research has systematically examined whether the provision of feedback following judgments leads to increased judgment accuracy. The current research explored the effects of providing feedback to therapists regarding client progress on the accuracy of therapists' judgments of change. The effect of feedback on therapists' confidence ratings regarding such judgments …

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 …

The scope of this research serves to aid in the understanding and counseling of survivors of loved ones who have committed suicide. This study will examine the phenomenon of survivors; specifically, what occurs as survivors move through the experience of grief and loss, as well as their individual grieving processes. The grieving process of those who deal with suicidal deaths of loved ones will be examined. Themes that emerge within the experiences of the participants will be identified and examined. Further, recommendations for the clinical practice of current and future counselors for work with suicide survivors will be suggested. Recommendations …

Initial Development Of A Healthy Living Curriculum Within Family Behavior Therapy For Substance Abuse, Holly B. Lapota

UNLV Theses, Dissertations, Professional Papers, and Capstones

A mother referred for child maltreatment and substance abuse treatment after her son tested positive for methamphetamines at birth participated in an in-home Family Behavior Therapy-Healthy Lifestyle intervention to eliminate substance use, improve parenting behaviors, lose weight, and develop better exercise habits. Twenty sessions were completed in 6 months that targeted familial communication, self-control, goal setting with contingency management, job getting skills, and stimulus control techniques. Upon termination from treatment, the participant’s self-report and urine testing was consistent with substance cessation, and she evidenced substantial improvements in her level of stress, family communication and relationships, and child maltreatment potential. She …

The Experience Of Feelings In Depression, Noelle L. Lefforge

UNLV Theses, Dissertations, Professional Papers, and Capstones

Emotions, such as sadness, guilt, and irritability, are at the core of depressive symptoms and suggest a need for an in-depth understanding of feelings, the experiential component of emotion, during depression. Therefore, the purpose of this study was to describe the experience of emotion in depressed participants and find out if these experiences are similar to those of nondepressed participants. Descriptive Experience Sampling (DES) was used to sample five depressed and four nondepressed participants for four days and then in a controlled setting while watching positive, negative, and neutral film clips. Due to the limited sample size, this study was …

The Advisor-Advisee Relationship: A Qualitative Study Of Advisee Perspectives, Paula M. Emke-Francis

UNLV Theses, Dissertations, Professional Papers, and Capstones

Attempts to understand the nature and course of advising relationships in clinical psychology doctoral training have been limited in number and scope. Furthermore, they have almost universally applied theoretical models derived for the explanation of different types of relationships, with very little empirical inquiry aimed at examining the advising relationship as it actually exists. The present study sought to better understand advisory relationships in clinical psychology doctoral training and propose a theoretical model related to the dimensions of the relationship that emerged.

This was accomplished via semi-structured interviews with 18 clinical psychology Ph.D. candidates from training programs across the United …

Verbal And Visual Learning And Memory Deficits As Trait Markers For Psychosis In Bipolar Disorder, Griffin P. Sutton

UNLV Theses, Dissertations, Professional Papers, and Capstones

The presence of neurocognitive deficits in the affective and psychotic psychiatric disorders (i.e., bipolar disorder with psychotic features, bipolar disorder without psychotic features, and schizophrenia) has been well documented, with such these deficits having been found to overlap across these diagnostic categories to a degree. Along with other types of evidence reported, these findings suggest that bipolar disorder and schizophrenia may not be isolated disorders as suggested by the current diagnostic criteria outlined in the DSM-IV (APA, 1994), but rather may be related disorders on a spectrum marked by bipolar disorder without psychosis on one end and by schizophrenia on …

Neuropsychological And Emotion Processing Abnormalities In Bipolar Disorder I And Ii, Carol Randall

UNLV Theses, Dissertations, Professional Papers, and Capstones

Bipolar disorder illness is marked by emotional lability and mood disturbance, as well as various neuropsychological deficits, and the neuroanatomical correlates of many of these deficits are beginning to be identified. Numerous studies have implicated specific cortical and sub-cortical abnormalities in areas associated with executive function, memory, motor function, and the processing of emotion. Although a large body of research has been devoted to the investigation of cognitive and emotion-processing deficits in bipolar disorder, relatively few studies have been devoted to the investigation of how these deficits differ among bipolar disorder subtypes. This is surprising in light of known symptomatological …

Exploring The Phenomena Of Inner Experience With Descriptive Experience Sampling, Janell M. Mihelic

UNLV Theses, Dissertations, Professional Papers, and Capstones

This study provides a survey of the phenomena of normal, everyday inner experience using the Descriptive Experience Sampling (DES) method. Results demonstrated that five types of inner experience (sensory awareness, feeling, unsymbolized thinking, inner seeing, and inner speech) occurred in approximately one-quarter of sampled moments and that there were significant individual differences regarding the frequency with which subjects experienced these phenomena. Three new dimensions (richness of inner experience, the number of experiences present, and the overall valence of the experience) along which inner experience could be characterized were identified and used reliably to characterize moments of experience. Finally, although there …

A Longitudinal Study Of Neurocognitive Deficits And Functional Outcome In Bipolar Disorder, Brian D. Leany

UNLV Theses, Dissertations, Professional Papers, and Capstones

Bipolar disorder is an affective disorder that, in addition to being characterized by depressive and expansive mood symptoms, often presents with neuropsychological deficits. Bipolar disorder not only impairs an individual’s cognitive abilities, but these cognitive impairments may also impact day-to-day activities causing functional impairment. In other psychiatric disorders such as schizophrenia, it has been shown that the neuropsychological deficits are predictive of poor, long term treatment outcome and functioning. However, while bipolar disorder affects nearly 1 - 2% of the U.S. population (Keck, McElroy, & Arnold, 2001), little is known about the extent that neurocognitive deficits may play in the …

Parental Abduction From The Perspective Of The Victims: Implications For Counselors, Mary Jo L. Gibbs

UNLV Theses, Dissertations, Professional Papers, and Capstones

This is a descriptive study that examined parental abductions from the perspective of the abductee. The results will help counseling professionals better to understand the psychological consequences of parental abduction, coping mechanisms that were used by the abducted children and counseling techniques and strategies that helped the children through this difficult time and after being returned to the left-behind parent.

A 32 multiple choice and short answer questionnaire was developed for this study. The survey consists of 12 closed answer (Yes or No) questions, three open ended questions, and seventeen demographic questions. The questionnaire was given through a phone interview …

Adult Estimation, Eye Movements And Math Anxiety, Robert T. Durette

UNLV Theses, Dissertations, Professional Papers, and Capstones

In this experiment the estimation ability of college undergraduates was examined using a number line task, with lines numbered 0-to-100, 0-to1,000 and 0-to-723 presented on a computer monitor. Previous research on kindergarteners' through 6^th graders' ability to estimate showed a progression from a logarithmic mental representation of numbers to a linear mental number line. Children's ability to estimate was found to correlate strongly with math achievement. We used this task to examine the hypothesis that remnants of the underlying logarithmic number line representation persist into adulthood despite formal educational experience with the number system (e.g. Dehaene, 1997). 0 to …

Parental Substance Abuse And Child Neglect: A Controlled Trial Of A Developed Treatment Manual, Valeria Romero

UNLV Theses, Dissertations, Professional Papers, and Capstones

The maltreatment of children is a devastating social problem in the United States. Many researchers and child welfare workers believe the recent increase in child neglect is directly correlated to an increase in parental substance abuse. There is a strong relationship between child neglect and parental substance abuse; however there are limited treatments that address both issues simultaneously. The present case studies evaluated the efficacy of a newly developed Family Behavior Therapy (FBT) program for child neglect and parental substance abuse utilizing controlled single case methodology. The Family Behavior Therapy (FBT) program is an integration of two published FBT interventions; …

Evaluating The Response Styles Theory Of Depression Using Descriptive Experience Sampling, Theresa A. Scott

UNLV Theses, Dissertations, Professional Papers, and Capstones

The Response Styles Theory of Depression states that there are two main responses to depression: distraction and rumination. Though it is believed distraction helps to alleviate feelings of dysphoria, the theory suggests rumination actually prolongs and intensifies episodes of depression (Nolen-Hoeksema, 1990, 1991). Rumination is also believed to play a role in the higher rates of depression seen in women (Nolen-Hoeksema, 1990, 1991). In 1987, Nolen-Hoeksema created the Response Styles Questionnaire (RSQ) as a measure to identify those who tend to use distraction or rumination as a psychological response to feelings of sadness or depression. The goal of this study …

Patient-Focused Research: Examining The Psychotherapist As A Feedback Receiver, Michael Haderlie

UNLV Theses, Dissertations, Professional Papers, and Capstones

The provision of feedback to psychotherapists regarding patient progress has been shown to produce improved therapy outcomes. However, little is known regarding therapists' responses to feedback. The current research examined novice therapists' perceptions of feedback based on the Outcome Questionnaire-45 (OQ-45). It was hypothesized that feedback would be considered more valuable when it was negatively-valenced (i.e., indicated that patient response to therapy was worse than expected). Patients (N = 19) of 5 trainee psychotherapists completed the OQ-45 before each session. Therapists then received feedback and rated it based on several characteristics. As hypothesized, negatively-valenced feedback was rated as more valuable …

Descriptive Experience Sampling Interactive Multimedia Training Tool By Arva Bensaheb Dr. Russell T. Hurlburt, Examination Committee Chair Professor of Psychology University of Nevada Las Vegas The present study developed a multimedia training tool to teach skills necessary to recognize two phenomena identified by the Descriptive Experience Sampling method: sensory awareness and unsymbolized thinking. The training tool was developed by subjecting successive versions to critical feedback provided by focus groups. Then training provided by this new training tool was compared with the training provided by extant literary materials on the two phenomena. Results suggest that the training tool was more effective …

Child Neglect And Trauma: The Additive Traumatic Effects Of Neglect On Maltreated Adolescents, Adrianna Rachel Wechsler

UNLV Theses, Dissertations, Professional Papers, and Capstones

Child maltreatment affects thousands of youths in the United States and poses numerous detrimental effects to individuals, families, and the community. Neglect is the most commonly reported and least studied form of child maltreatment. All types of child maltreatment may result in negative outcomes, but the chronic and pervasive nature of child neglect poses a significant threat to child development. No studies have been published evaluating the role of child neglect in the development of Posttraumatic Stress Disorder (PTSD) and PTSD-related symptoms. This study examined whether neglect has an additive traumatic effect on maltreated youth. The first hypothesis was that …

Neurocognitive Deficits And Functional Outcome In Bipolar Disorder, Danielle T. Bello

UNLV Theses, Dissertations, Professional Papers, and Capstones

Bipolar disorder affects approximately 1% of the population. It is a severe and debilitating illness, causing serious impairment of interpersonal, occupational and social functioning. The disorder is characterized by marked mood swings as well significant neurocognitive deficits. Based on work with other psychiatric and neurological disorders, neurocognitive deficits in bipolar disorder are expected to be strong predictors of functional capacity. However, few studies have evaluated the consequences of neurocognitive deficits in this disorder. Most available studies have focused on the clinical correlates of functional outcome, such as number of hospitalizations, age of disorder onset, and severity of symptoms. While useful, …

Functions And Correlates Of Deliberate Self-Harm Among Adjudicated Male Adolescents, Jenna Silverman

UNLV Theses, Dissertations, Professional Papers, and Capstones

Deliberate self-harm (DSH) is self-inflicted physical injury without suicidal intent. Recent studies indicated that more adolescent males engage in DSH than previously identified. Research demonstrated that DSH is common in forensic settings and highly correlated with several mental health disorders. This study included 103 adjudicated male adolescents assessed for DSH and mental health concerns. Twenty-two participants with DSH history and 21 controls were interviewed about coping skills, mental health problems, and DSH functions. Results indicated that 66%, especially African American and Hispanic participants, reported DSH history. Participants with DSH history reported more aggression, emotional lability, alienation/boredom, and internalizing disorders but …

Posttraumatic Stress Disorder And Other Consequences Of A Picu Admission, Stephanie Ann Stowman

UNLV Theses, Dissertations, Professional Papers, and Capstones

Currently, there is a paucity of literature regarding children's experiences in a pediatric intensive care unit (PICU) relative to caregivers' experiences. Children admitted to a PICU and their caregivers are at risk for various psychopathology. Disorders commonly identified in seriously ill children include depression, anxiety, acute stress disorder, and posttraumatic stress disorder. Caregivers of seriously ill children are at increased risk of depression, generalized anxiety disorder, acute stress disorder, and posttraumatic stress disorder. Researchers often fail to examine all relevant psychopathology and contributing factors and stressors, such as family environment, in seriously ill children and their caregivers. This study assessed …
