Comparative Organizational Assessments And Partenship Potential For Sekou Pou Nanm-Yo And Asirans Community Counseling Center, Lauren M. Mawe May 2016

Comparative Organizational Assessments And Partenship Potential For Sekou Pou Nanm-Yo And Asirans Community Counseling Center, Lauren M. Mawe

Sustainability and Social Justice

This paper assesses the organizational capacity of two small Non-Governmental Organizations (NGOs) in Port-Au-Prince Haiti. Each NGO has a staff of under 15 members. At the time of the assessment, they were both in early stages of their development, with one in its first year of operations, and the other in its fifth year. Both embody grassroots, community organizations because of their connections to the communities in which they work, their willingness to travel to those communities, and their predominantly Haitian staff. The fieldwork included interviews, focus groups, and three months of participant observation and work with these organizations. In …

An Analysis Of The Factors Influencing Bored And Emotional Eating: Should Bored Eating Exist As A Separate Construct?, Erin Elizabeth Stuck May 2016

An Analysis Of The Factors Influencing Bored And Emotional Eating: Should Bored Eating Exist As A Separate Construct?, Erin Elizabeth Stuck

USC Aiken Psychology Theses

Emotional eating pertains to eating in response to negative emotional experiences, and can occur for a variety of reasons. Individuals may emotionally eat as a means of submerging themselves into positive reinforcing states, as a way of coping, or as a distraction from their negative emotional experience (Cialdini, 1973; Kemp, Bui, & Grier, 2013; and Spoor et al., 2006). Historically, emotional eating has included boredom. Recent research has suggested that bored eating may be a separate construct from emotional eating (Koball et al., 2012). Thus, the present study investigated the variables associated with both emotional eating and bored eating with …


Disruptive Behavior Disorders In Childhood And Criminal Justice System Involvement In Adolescence And Emerging Adulthood: Pilot Results Among Puerto Rican Youth, Marjorine Castillo May 2016

Disruptive Behavior Disorders In Childhood And Criminal Justice System Involvement In Adolescence And Emerging Adulthood: Pilot Results Among Puerto Rican Youth, Marjorine Castillo

Theses and Dissertations

The relationship between Disruptive Behavior Disorders (DBD) in childhood and arrest during adolescence and emerging adulthood was explored in a community sample of 162 Puerto Rican children who lived in the South Bronx, NYC when first recruited. Results indicate a significant link between having DBD in childhood and later arrest.


The Relation Of Adolescent Narcissism And Prosocial Behavior With Cooperative And Competitive Attitudes, Erin V. Moran May 2016

The Relation Of Adolescent Narcissism And Prosocial Behavior With Cooperative And Competitive Attitudes, Erin V. Moran

Honors Theses

Narcissism has been correlated with prosocial behavior in adolescents (Kauten & Barry, 2014, 2016). However, whether adolescents with high levels of narcissism use more egoistic (i.e., self-serving) or altruistic (i.e., helping others with no direct personal benefit) prosocial behaviors has not been investigated. This issue was addressed in the present study, and attitudes of cooperation and competition were also examined as moderators in these relations. The current study involved 147 at-risk adolescents, ages 16 to 18 (113 males, 34 females) who were enrolled in a residential program. The data were collected through self-report questionnaires which assessed narcissism (i.e., non-pathological, grandiose, …


Parenting Practices And Young Adults’ Emotional Distress: The Moderating Roles Of Family Structure And Race, Nathan Alexander Winner May 2016

Parenting Practices And Young Adults’ Emotional Distress: The Moderating Roles Of Family Structure And Race, Nathan Alexander Winner

Master's Theses

Authoritarian parenting practices are more common among African American families, and appear to include fewer disadvantages in regards to child outcomes compared to White/non-Hispanic families who use these same practices. Little is known about why these racial differences occur, although family structure may play a role. The present study sought to understand the role of family structure and race in moderating the effects of parenting practices on college student mental health outcomes. College students reported on the parenting practices of their caregivers, as well as their race, family structure, characteristics of their familial environment, and socioeconomic status. Levels of depression, …


Vocational Implications Of Cult Involvement, Melissa Dawn Jones Wilkins May 2016

Vocational Implications Of Cult Involvement, Melissa Dawn Jones Wilkins

Graduate Theses and Dissertations

Currently, the majority of studies published on cult membership have been quantitative and have focused primarily on theories and trends about cult membership. These studies have been insufficient in shedding light on the individual’s experience. Qualitative studies are necessary to explore the individual’s accounts of their experiences with past cult involvement and the impact these experiences have on employment. Because of the potential vocational impacts of cult involvement, it is valuable to explore the psychoSocial aspects of work. A qualitative methodology informed by phenomenology was utilized to investigate the unique experience of individuals obtaining employment after leaving a cult. Seven …


Embedded Performance Measures Within The Delis-Kaplan Executive Function System, Daniel Olsen May 2016

Embedded Performance Measures Within The Delis-Kaplan Executive Function System, Daniel Olsen

Doctor of Psychology (PsyD)

It has become increasingly clear many patients do not manifest sufficient effort over the course of a neuropsychological evaluation (Horner, VanKirk, Dismuke, Turner, & Muzzy, 2014). While tests of memory and learning are considered to be the gold-standard in effort measurement, they are vulnerable to coaching (Bianchini, Greve, & Love, 2003). Fortunately, interest in assessing effort through other cognitive domains has grown over the last few years. In the current study, participants were divided into two groups, simulators and controls. All participants completed the Medical Symptom Validity Test (MSVT, Green, 2004), the Trail Making Test (TMT), the Verbal Fluency Test …


Factors That Affect Recidivism For Psychiatric Patients In Emergency Departments, Meghan Polits May 2016

Factors That Affect Recidivism For Psychiatric Patients In Emergency Departments, Meghan Polits

Doctor of Psychology (PsyD)

Hospital recidivism for suicimicidal, and psychiatric patients is a burden on the medical system due to the high cost associated with each visit. Factors affecting psychiatric patients in the Emergency Department (ED) in two rural hospitals in the Pacific Northwest were assessed using data routinely collected at intake in an effort to determine patient risk factors for repeat visits. Additionally, patients identified as repeat visitors were assessed for any significant differences in how quickly they were readmitted. Logistic regression results indicate having a diagnosis of a psychotic disorder or bipolar disorder, being uninsured or on Oregon Health Plan insurance (i.e., …


Investigating Inner Experience While Reading An Erotic Short Story, Leiszle Rae Lapping-Carr May 2016

Investigating Inner Experience While Reading An Erotic Short Story, Leiszle Rae Lapping-Carr

UNLV Theses, Dissertations, Professional Papers, and Capstones

An investigation of the phenomenological aspects of sexual response is needed for a more comprehensive understanding of human sexuality. To obtain high fidelity descriptions of inner experience during a sexually oriented task, the current study used Descriptive Experience Sampling (DES) while seven participants read an erotic short story. Participants were trained in DES by sampling during everyday activities. After training, they were sampled while reading two classic short stories on a web-based program. Participants then sampled their experience while reading an erotic short story using the same web-based program. Some of the participants were willing to discuss their inner experience …


The Effects Of Psychopathic Traits On Social Support Networks, Stephanie Marie Molina May 2016

The Effects Of Psychopathic Traits On Social Support Networks, Stephanie Marie Molina

UNLV Theses, Dissertations, Professional Papers, and Capstones

Psychopathy is a personality disorder with distinctive behavioral, emotional and interpersonal features. The dual process model of psychopathy conceptualizes the construct via two distinct factors: fearless dominance (FD) and impulsive antisociality (IA). While individuals higher in psychopathic traits are less likely to cooperate with others, research examining the impact of psychopathy on individuals’ social networks is lacking. In the current study, 377 first year undergraduate students completed the Multidimensional Personality Questionnaire, the Ten Item Personality Inventory, and ratings regarding their social networks via Qualtrics. Students were asked to list up to ten friends and rate their relationship via a newly …


Identifying Maltreated Youth At High Risk For Posttraumatic Symptom Clusters Using Nonparametric Modeling, Emma H. Ross May 2016

Identifying Maltreated Youth At High Risk For Posttraumatic Symptom Clusters Using Nonparametric Modeling, Emma H. Ross

UNLV Theses, Dissertations, Professional Papers, and Capstones

Certain individual factors may heighten a youth’s risk for PTSD symptoms following maltreatment (Kearney et al., 2010). This study aimed to identify maltreated youth at highest risk for re-experiencing, avoidance, and hyperarousal symptoms of PTSD. This study evaluated interactions among several demographic, affective, and cognitive variables to determine which subgroups of maltreated youth are most likely to manifest diagnostic PTSD symptom presentations in the aforementioned clusters. Participants included 400 ethnically diverse youth aged 7-18 years from Department of Family Services (DFS)-related sites in Las Vegas. This study employed Binary Recursive Partitioning (BRP) methods to identify highest risk subgroups for each …


Concurrent Mental Health And Sport Performance Enhancement In An Athlete Initiating Behavioral Intervention With No Assessed Pathology: A Case Examination Supporting Optimization, Yulia Gavrilova May 2016

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 …


Anger And Sadness Rumination And Their Impact On Momentary Changes In Impulsivity And Pain Tolerance: Implications For The Development Of Suicide Risk, Keyne Catherine Law May 2016

Anger And Sadness Rumination And Their Impact On Momentary Changes In Impulsivity And Pain Tolerance: Implications For The Development Of Suicide Risk, Keyne Catherine Law

Master's Theses

Recent research in suicide has called for an increased focus on factors that facilitate an individual’s transition from suicidal ideation to action (Klonsky & May, 2014). Rumination, the repetitive fixation on negative emotional material, has been associated with not only increased suicidal ideation but also a history of self-injury and suicide attempts (Morrison & O’Connor, 2008), suggesting that it may contribute to the ability to inflict lethal and non-lethal self-harm. Given that past research has found physiological differences between low (ex. sadness) and high (ex. anger) arousal negative affective states, the present thesis project sought to examine the effects of …


The Dark Triad And Hexaco Model Of Personality In Relational Aggression, Niki M. Knight May 2016

The Dark Triad And Hexaco Model Of Personality In Relational Aggression, Niki M. Knight

Master's Theses

Past research has linked relational aggression (RA) to many forms of psychological maladjustment among children and early adolescents. Although less is known about RA among emerging adults, there is a growing body of research demonstrating a number of adverse correlates. This literature has sparked an interest in examining the role of personality in RA. Most investigations to date have focused on the Five Factor Model; however, the six factor HEXACO model of personality (Ashton et al., 2004) may offer some advantages in studying RA. Moreover, the manipulative and often covert nature of RA among emerging adults has theoretical overlap with …


Effects Of A Brief Mindfulness Induction On Death-Related Anxiety, David Matthew Schultz May 2016

Effects Of A Brief Mindfulness Induction On Death-Related Anxiety, David Matthew Schultz

Master's Theses

Terror management theory postulates that the behavior and beliefs of individuals are influenced on some level by an underlying aversion to death. Mortality salience, the conscious awareness of one’s own impending death, creates behavioral changes in individuals compared to non-mortality salient individuals. These changes in behavior are referred to as distal and proximal defense mechanisms. Relatively little research has investigated mechanisms to buffer effects of mortality salience. Mindfulness refers to a conscious awareness and acceptance of moment-to-moment experiences. By allowing individuals to take a regulated view of difficult situations, mindfulness may attenuate the negative effects of mortality salience. The present …


Comparing The Utilization Of The Peds And Psc-17 Screeners In A Pediatric Primary Care Clinic, Halie L. Dyer May 2016

Comparing The Utilization Of The Peds And Psc-17 Screeners In A Pediatric Primary Care Clinic, Halie L. Dyer

Undergraduate Honors Theses

Behavioral problems exhibited in early childhood can predict continued behavioral difficulties into adolescence and adulthood and can result in poor social functioning and health outcomes. Early identification of these concerns is necessary in order to connect families with appropriate interventions that thwart a negative trajectory. In pediatric offices, developmental screeners and pediatric surveillance are efficient and reliable methods of assessing behavioral concerns, which can help to quickly connect families with services. This study examines two methods of screening for behavioral concerns and the impact on on-site behavioral health referrals for children 4 and 5 years of age at a local …


Arrest Or Hospitalization? An Examination Of The Relationship Between Psychiatric Symptoms, Traumatic Childhood Experiences, And Socio-Ecological Factors In Forensic Mental Health System Responses To Offender Behavior, Stephanie Mersch, Jill D. Stinson, Megan Quinn May 2016

Arrest Or Hospitalization? An Examination Of The Relationship Between Psychiatric Symptoms, Traumatic Childhood Experiences, And Socio-Ecological Factors In Forensic Mental Health System Responses To Offender Behavior, Stephanie Mersch, Jill D. Stinson, Megan Quinn

Undergraduate Honors Theses

It has been well documented that Adverse Childhood Experiences (ACEs) lead to unfavorable outcomes in later life, especially with regard to health and psychological outcomes. Recent research has demonstrated the impact of early childhood adversity on the onset of aggression and illegal behavior. However, often those with mental illness diagnoses with comorbid behavioral problems exhibit trajectories that include both arrest and hospitalization. While some are arrested for their criminal behavior, others are hospitalized. This begs the question: are those with mental illness and behavioral problems more likely to be arrested, or hospitalized, for their early behavioral problems? In the current …


The Effects Of Brief, Passive Psychoeducation On Suicide Literacy, Stigma, And Attitudes Toward Help-Seeking Among Latino Immigrants Living In The United States, Aubrey Renee Dueweke May 2016

The Effects Of Brief, Passive Psychoeducation On Suicide Literacy, Stigma, And Attitudes Toward Help-Seeking Among Latino Immigrants Living In The United States, Aubrey Renee Dueweke

Graduate Theses and Dissertations

Latino immigrants drastically underutilize mental health treatment services compared to other ethnic groups, despite rates of mental illness that are comparable to those observed among the general population. With regards to suicidal behavior specifically, twice as many Latino suicide attempters do not seek or receive psychiatric services in the year prior to attempting suicide, compared to non-Latino White attempters. The main objective of this study was to investigate whether provision of brief, passive psychoeducation in the form of a brochure could increase suicide literacy (i.e., recognizing suicidal behavior, understanding risk factors and causes of suicidal behavior), reduce stigma toward suicidal …


A Preliminary Investigation Of Positive Imagery Training To Reduce Risk For Suicidal Behavior Among Adolescent Girls, Sasha Micaella Rojas May 2016

A Preliminary Investigation Of Positive Imagery Training To Reduce Risk For Suicidal Behavior Among Adolescent Girls, Sasha Micaella Rojas

Graduate Theses and Dissertations

Suicide is the second leading cause of death among adolescents, with risk for suicidal thoughts and suicidal behavior emerging during adolescence particularly among girls. Consistent with theory and empirical evidence, the current study examined the effects of Socially-focused positive imagery training among a small sample of adolescent girls evidencing suicidal thoughts. This preliminary small n design also allowed for a detailed assessment of acceptability of imagery training for the adolescent sample. Risk for suicidal intent was indexed by 1) negative affect, 2) positive affect, 3) greater resting right (relative to left) prefrontal asymmetry, 4) perceived Social isolation, and 5) suicidal …


The Role Of Child Anxiety In Parent Sick Role Reinforcement, Sarah Ann Bilsky May 2016

The Role Of Child Anxiety In Parent Sick Role Reinforcement, Sarah Ann Bilsky

Graduate Theses and Dissertations

A large body of evidence suggests that parents can facilitate offspring anxiety in response to bodily arousal. These learning experiences are referred to as “sick role reinforcement,” and are particularly important during adolescence, given the profound bodily changes (e.g., puberty) that characterize this period. Sick role reinforcement is likely important in the context of panic disorder (PD). Panic theorists suggest that parents may enhance panic vulnerability by increasing the threat value of bodily sensations. Although a sizeable body of work has examined the role of parent behavior in these processes, few have examined offspring factors in this process. Additionally, little …


Cognitive Functioning As A Moderator In The Relation Between Externalizing Behavior Problems In Children With Autism Spectrum Disorder And Stress Among Their Parents, Robyn M. Riley May 2016

Cognitive Functioning As A Moderator In The Relation Between Externalizing Behavior Problems In Children With Autism Spectrum Disorder And Stress Among Their Parents, Robyn M. Riley

Honors Theses

It is known that externalizing behavior problems among children with autism spectrum disorder (ASD) are related to parental stress among parents. This study examined how cognitive functioning levels of children with ASD may moderate this relation in a group of 27 children (ages 7 to 16 years) with a diagnosis of ASD. Children were tested on a brief measure of intelligence to estimate their cognitive functioning. Parents completed measures of the children’s ASD symptom severity and externalizing behaviors as well as a measure of their own levels of parental stress. Hierarchical regression analyses indicated that ASD symptoms and cognitive functioning …


The Relationship Of Empathy And Impulsivity To The Dark Tetrad Of Personality, Ashlee Justice Apr 2016

The Relationship Of Empathy And Impulsivity To The Dark Tetrad Of Personality, Ashlee Justice

Electronic Theses and Dissertations

Though relationships between empathy, impulsivity, and personality traits making up the Dark Tetrad of personality have been studied individually, the relationship of empathy and impulsivity to the Dark Tetrad of personality simultaneously has not been studied. The current study examined the relationship of both empathy and impulsivity to the Dark Tetrad simultaneously, and assessed specific combinations of traits, empathy, and impulsivity. Participants from a private university completed online surveys. Correlations and predictions of variables were examined. Individuals who rated high on Machiavellianism, psychopathy, and sadism had significantly lower scores on empathy subscales, and individuals rating high on these as well …


The Role Of Emotional Distress In Predicting Opiate Analgesic Medication Use In Chronic Pain Patients, Amy E. Kupper Apr 2016

The Role Of Emotional Distress In Predicting Opiate Analgesic Medication Use In Chronic Pain Patients, Amy E. Kupper

Clinical Psychology Dissertations

Chronic pain is a common, costly, and debilitating problem. The biopsychosocial model purports that biological, psychological, and social factors are involved in the experience of chronic pain. Multidisciplinary pain management programs adhere to the biopsychosocial model and successfully treat and manage chronic pain. Depression, anxiety, and opiate analgesic medication misuse and abuse are significant problems faced by many individuals with chronic pain, however these relationships are not well understood. This study examined a sample of 248 chronic pain patients who completed a multidisciplinary pain management program. Two hypotheses were tested. First, it was hypothesized that the relationships amongst change in …


Post-Traumatic Growth In Cancer Survivors: Narrative Markers And Functions Of The Experience's Transformation, Maria Luisa Martino, Maria Francesca Freda Apr 2016

Post-Traumatic Growth In Cancer Survivors: Narrative Markers And Functions Of The Experience's Transformation, Maria Luisa Martino, Maria Francesca Freda

The Qualitative Report

The concept that a traumatic experience, such as a cancer, can lead to a positive change and transformation of self, life and relationships was named as post-traumatic growth (PTG). A large amount of research measured PTG in cancer survivors arguing an interpretation of the construct as an outcome. Recently, qualitative research shows different types of narrative of PTG, but the narrative markers and their functions of transformation remain still unclear. Within a mixed-method, we aim to highlight the narrative markers and their transformative functions, underlying the PTG, within 12 cancer survivors’ narratives with medium/high and medium/low level of PTG. A …


Therapy Outcomes: Difference Between Latino And Non-Latino Foster Youth, Alicia G. Escobedo, Corie E. Schwabenland, Rosana M. Aguilar, Saralyn Ruff Apr 2016

Therapy Outcomes: Difference Between Latino And Non-Latino Foster Youth, Alicia G. Escobedo, Corie E. Schwabenland, Rosana M. Aguilar, Saralyn Ruff

Creative Activity and Research Day - CARD

Children in foster care experience a range of psychological symptoms due to their experiences with maltreatment. Latinos are a growing population within foster care, reflective of their growing numbers in the United States. Latinos often do not seek out mental health services and many face obstacles related to language, transportation, and lack of family support.

The current study describes treatment parameters of Latino and non-Latino foster youth receiving long-term, pro-bono psychotherapy through a non-profit. Telephone interviews were completed with the youths’ therapists at the start and end of treatment. Among the completed cases, nine were identified as Latino patients. An …


Examining Multi-Session Brief Intervention For Substance Use In Primary Care: Research Methods Of A Randomized Controlled Trial., Jaclyn E Chambers, Adam C Brooks, Rachel Medvin, David S Metzger, Jennifer Lauby, Carolyn M Carpenedo, Kevin E Favor, Kimberly C Kirby Apr 2016

Examining Multi-Session Brief Intervention For Substance Use In Primary Care: Research Methods Of A Randomized Controlled Trial., Jaclyn E Chambers, Adam C Brooks, Rachel Medvin, David S Metzger, Jennifer Lauby, Carolyn M Carpenedo, Kevin E Favor, Kimberly C Kirby

College of Science & Mathematics Departmental Research

BACKGROUND: Brief interventions such as Screening, a single session of Brief Intervention, and Referral to Treatment (SBIRT) have shown mixed effectiveness in primary care. However, there are indications that multi-session brief interventions may demonstrate more consistently positive outcomes, and perhaps a more intensive approach would be of benefit in addressing substance use in primary care. This study compared the effectiveness of SBIRT with a single BI session (BI/RT) to a multi-session brief-treatment intervention (BI/RT+) in primary care. We also developed easy-to-use, evidence-based materials to assist clinicians in delivering these interventions.

METHODS/DESIGN: This study was conducted in three Federally Qualified Healthcare …


Fear Of Missing Out In Relationship To Emotional Stability And Social Media Use, Jacqueline N. Germaine-Bewley Apr 2016

Fear Of Missing Out In Relationship To Emotional Stability And Social Media Use, Jacqueline N. Germaine-Bewley

Scholarly and Creative Works Conference (2015 - 2021)

The purpose of social media is to share information and connect with other users online. In recent years, extensive social media use has begun to emerge among users and can be related to increased time on social media outlets. Increased time on social media platforms has raised concern about a new phenomenon called the Fear of Missing out (FoMO; Przybylski, Murayamab, DeHaanc, and Gladwelld, 2013). FoMO is defined by an individual’s anxiety or worry that other people are having more rewarding experiences than they are. FoMO is characterized by an increased desire to constantly stay connected with online friends on …


Teaching Children With Autism Who Have Difficulty Mastering Auditory Discriminations, Sarah Lichtenberger Apr 2016

Teaching Children With Autism Who Have Difficulty Mastering Auditory Discriminations, Sarah Lichtenberger

Research and Creative Activities Poster Day

Simple and conditional visual and auditory discrimination repertoires are critical components of many skills necessary for daily functioning, including communication, academic, and daily-living skills (Green, 2001). When auditory discrimination is not under instructional stimulus control, it can result in delayed acquisition of new skills and limit academic progress. The purpose of this study was to teach auditory discrimination to children with autism who had little to no progress on classroom procedures that required auditory discrimination, such as selecting an object from an array when given the name of the object as the direction. Auditory discrimination was taught starting with teaching …


Previous Exposure To Lsd Fails To Enhance The Psychomotor Stimulant Effects Of D-Amphetamine In Male Sprague-Dawley Rats, Keli Herr Apr 2016

Previous Exposure To Lsd Fails To Enhance The Psychomotor Stimulant Effects Of D-Amphetamine In Male Sprague-Dawley Rats, Keli Herr

Research and Creative Activities Poster Day

  • The hallucinogenic effects of lysergic acid diethylamide (LSD) have been largely attributed to its high affinity for 5-HT2A receptors. However, LSD also has a high affinity at several other monoamine receptors (Nichols, 2004; Passie et al., 2008).
  • The contribution of dopaminergic mechanisms to LSD’s behavioral effects have not been investigated to the same extent that serotonergic mechanism have been studied. Some authors have hypothesized that chronic treatment of rats with LSD may produce a persistent behavioral state characterized by sensitivity to dopamine agonists (Marona-Lewicka and Nichols, 2007).
  • Repeated exposure to psychostimulant drugs is known to produce progressive increases in locomotor …
