Sexual Coercion And Sexual Violence At First Intercourse Associated With Sexually Transmitted Infections, Corrine M. Williams, Emily R. Clear, Ann L. Coker Oct 2013

Sexual Coercion And Sexual Violence At First Intercourse Associated With Sexually Transmitted Infections, Corrine M. Williams, Emily R. Clear, Ann L. Coker

CRVAW Faculty Journal Articles

BACKGROUND: Violence against women has been associated with subsequent risky sexual behaviors and sexually transmitted infections (STIs). We explored whether sexual coercion or violence at first intercourse was associated with self-reported STIs.

METHODS: Using nationally representative data from the 2006 to 2010 National Survey of Family Growth, we analyzed female respondents aged 18 to 44 (n = 9466) who answered questions on coercion at first intercourse (wantedness, voluntariness, and types of force used) and STIs using logistic regression analyses. We explored degrees of coercion, which we label as neither, sexual coercion (unwanted or nonphysical force), or sexual violence (involuntary or …


The Relationship Between Self-Presentation Concerns And Pre-Game Affect Among Adolescent Football Players, Leslie W. Podlog, Marc Lochbaum, Jens Kleinert, James Dimmock, Maria Newton, Stefanie Podlog (Nee Schulte) Sep 2013

The Relationship Between Self-Presentation Concerns And Pre-Game Affect Among Adolescent Football Players, Leslie W. Podlog, Marc Lochbaum, Jens Kleinert, James Dimmock, Maria Newton, Stefanie Podlog (Nee Schulte)

Athletic Training Collection

Background:

The influence of self-presentation concerns on the adolescent sport experience has received scant empirical attention. The purpose of this investigation was to prospectively examine the relationship among self-presentational concerns and pre-game affective states among middle and high school aged football players.

Methods:

American football players (n = 112; mean age = 15.57 years) completed a measure of self-presentational concerns (SPSQ, McGowan, et al., 2008) a week prior to the measurement of selected pre-game affective states (i.e., attentiveness, self-assurance, serenity, and fear).

Results:

Regression analyses revealed that concerns about appearing athletically untalented negatively contributed to the significant prediction ( p …


Exploring Adolescent Experiences Of Race, Ethnicity, And Socioeconomic Status In Counseling Relationships: A Qualitative Approach, Christina Crans Aug 2013

Exploring Adolescent Experiences Of Race, Ethnicity, And Socioeconomic Status In Counseling Relationships: A Qualitative Approach, Christina Crans

Dissertations

The ACA Code of Ethics (2005) states the expectation that counselors must understand the diverse backgrounds of their clients. In addition, counselors are called to understand how their personal cultural identity informs and affects the counseling process. Yet there is paucity in the literature regarding the multicultural client experience within a counseling relationship. Of the few multicultural counseling studies that attempt to address multicultural client concerns, the approach has been quantitative or reliant on counselor self-report. In addition, the lived counseling experiences of adolescents and individuals from lower socioeconomic status (SES) is absent in present literature. This qualitative study examined …


Suicide Attempts Among Emotionally And Behaviorally Disturbed Adolescents Removed From The Home, Faith M. Wanja Jul 2013

Suicide Attempts Among Emotionally And Behaviorally Disturbed Adolescents Removed From The Home, Faith M. Wanja

Master's Theses or Doctor of Nursing Practice

This study was conducted to examine the relationship between adolescent suicide behavior and the age of removal from home amongst children with emotional and behavioral disturbance. The study aims to determine whether a child�s removal from home can be counted as a viable basis for the development of suicide prevention programs and an expansion for evidence based practices. The study was conducted using archived de-identified data collected and provided by a private not-for-profit behavioral health treatment facility located in rural Kansas. The participants included male and female adolescents between the ages of thirteen to eighteen years old that were admitted …

The Human Brain Processes Syntax In The Absence Of Conscious Awareness., Laura Batterink, Helen J Neville May 2013

The Human Brain Processes Syntax In The Absence Of Conscious Awareness., Laura Batterink, Helen J Neville

Brain and Mind Institute Researchers' Publications

Syntax is the core computational component of language. A longstanding idea about syntactic processing is that it is generally not available to conscious access, operating autonomously and automatically. However, there is little direct neurocognitive evidence on this issue. By measuring event-related potentials while human observers performed a novel cross-modal distraction task, we demonstrated that syntactic violations that were not consciously detected nonetheless produced a characteristic early neural response pattern, and also significantly delayed reaction times to a concurrent task. This early neural response was distinct from later neural activity that was observed only to syntactic violations that were consciously detected. …


Differential Behavioral Effects Of Ketamine Between Adolescent And Adult Sprague-Dawley Rats, Maria A. Greenwood May 2013

Differential Behavioral Effects Of Ketamine Between Adolescent And Adult Sprague-Dawley Rats, Maria A. Greenwood

Theses and Dissertations

The dissociative anesthetic ketamine has been subject to growing abuse worldwide, particularly in adolescents. This project compared the effects of ketamine in conditioned place preference and intravenous self-administration in adolescent (PND 28-50) and adult (>PND70) Sprague-Dawley rats. Cocaine served as a positive control. In CPP, adolescents demonstrated preferences for ketamine, while adults developed an aversion. In the self-administration procedure, adults acquired the behavior more rapidly, but there was no difference in the percentage of subjects reaching acquisition nor in responding under a progressive ratio schedule for either drug. The CPP results suggest that adolescents have a greater sensitivity to …


Implementing Dialectical Behavior Therapy For Adolescents In An Acute Inpatient Psychiatric Setting, Thomas Andrew Field May 2013

Implementing Dialectical Behavior Therapy For Adolescents In An Acute Inpatient Psychiatric Setting, Thomas Andrew Field

Dissertations, 2014-2019

Although evidence-based practices (EBPs) have been identified in the literature, insufficient information exists about how to successfully implement them. As a result, implementation efforts have been met with failures. Little is currently known about what affects the success of implementation efforts for best practices such as Dialectical Behavior Therapy for adolescents (DBT-A) in an acute inpatient psychiatric setting (AIPS). A longitudinal multiphase mixed methods case study examined an implementation effort to provide DBT-A in an AIPS over a 24-month period. The process of implementation was investigated through in-depth interviews, a focus group, and field observations. Six categories were identified that …


Adolescent Substance Abuse Treatment: Does Family Systems Therapy Improve Family Functioning And Decrease Drug Use?, Darin J. Wallis Jan 2013

Adolescent Substance Abuse Treatment: Does Family Systems Therapy Improve Family Functioning And Decrease Drug Use?, Darin J. Wallis

Electronic Theses and Dissertations

Family systems therapy is a way of working with individuals, couples, families, or a group of people that emphasizes relationships and a person's/family's greater "system" as important factors in establishing change and health (Haley, 1976; Minuchin, 1974). Treating adolescent substance abuse with family systems therapy has been demonstrated in the literature as being an effective method of intervention (Coatsworth, Santisteban, McBride, & Szapocznik, 2001; Kumfer & Alvarado, 2003; Leichtling, Gabriel, Lewis & Vander Ley, 2006; Liddle, 2002; Liddle et al., 2001; Rowe & Liddle, 2003), as the various ecological and epidemiological factors associated with adolescent substance abuse can be addressed …


Report Of A Deaf Child With Tourette's Disorder., Cathy J Chovaz Jan 2013

Report Of A Deaf Child With Tourette's Disorder., Cathy J Chovaz

Psychology

This is a case study of a deaf child with Tourette's Disorder (TD). Hearing parents and mental health clinicians unfamiliar with typical behaviors of deaf children may have difficulties differentiating the clinical presentation of symptoms of TD from the effects of deafness, as well as in implementing appropriate interventions. This case study reports the history, symptoms, diagnostic process, and treatment interventions. This is relevant for furthering the clinical knowledge of mental health professionals working with Deaf, deaf, and hard-of-hearing children and adolescents.

Temporal Relationships Between Psychological Distress And Risky Behaviors In A Sample Of Homeless And At-Risk Youth, Tegan Lesperance Jan 2013

Temporal Relationships Between Psychological Distress And Risky Behaviors In A Sample Of Homeless And At-Risk Youth, Tegan Lesperance

Wayne State University Theses

The present study examined temporal relationships between psychological distress and two types of risk behavior; risky sexual behavior and substance abuse/dependence, in a sample of 253 at-risk youth. Using structural equation modeling, the self-medication and risk-first hypotheses were tested using longitudinal data spanning 7 years. Each model lent support to both hypotheses, further supporting the relationship between risk-taking behaviors and psychological distress among youth. Early psychological distress predicted later involvement in risky sexual behaviors, while later distress predicted substance abuse/dependence. Earlier risky sexual behaviors and substance abuse/dependence predicted psychological distress at later time points. These findings suggest the need to …


Parental Influence On Inhalant Use, Alina M. Baltazar, Gary L. Hopkins, Duane C. Mcbride, Curtis J. Vanderwaal, Sara Pepper, Sarah Mackey Jan 2013

Parental Influence On Inhalant Use, Alina M. Baltazar, Gary L. Hopkins, Duane C. Mcbride, Curtis J. Vanderwaal, Sara Pepper, Sarah Mackey

Faculty Publications

The purpose of this article is to examine the dynamics of the relationship between parents and their adolescent children and their association with lifetime and past-month inhalant usage. The population studied was seventh- through ninth-grade students in rural Idaho (N = 570). The authors found a small, but consistent, significant inverse correlation between parental bonding and monitoring of behavior and inhalant usage. There was also a significant positive correlation between verbally aggressive behavior in the family and inhalant use. The data imply that family interaction may play a significant role in the use of inhalants and that the family can …


Feasibility Of A Nutrition Training Program On Improving Self-Efficacy And Life Skill Development For Adolescents With Sickle Cell Disease, Ashara Calisse-Atchley Cashaw Jan 2013

Feasibility Of A Nutrition Training Program On Improving Self-Efficacy And Life Skill Development For Adolescents With Sickle Cell Disease, Ashara Calisse-Atchley Cashaw

PCOM Psychology Dissertations

Adolescents with sickle cell disease (SCD) are at risk for growth and nutritional
deficiencies due to poor dietary intake. Presently, no efficacious behavioral intervention exists to address the nutritional need in SCD management. The Good Nutrition 4Me Living with SCD program is a multi-component intervention, developed to improve knowledge base and the dietary habits of adolescents living with SCD. This report reviews the outcomes for 5 adolescents that participated in this 5-week program. Dietary intake was monitored daily via text messaging and progress with goals was reviewed weekly in the group sessions. Parents were also updated on their adolescent’s progress …


Examination Of Physician Decision Making With Children And Adolescents Diagnosed With Long Qt Syndrome: A Qualitative Study, Julie Radico Jan 2013

Examination Of Physician Decision Making With Children And Adolescents Diagnosed With Long Qt Syndrome: A Qualitative Study, Julie Radico

PCOM Psychology Dissertations

Physicians are faced with ongoing challenges in diagnosing long QT syndrome (LQTS) and the uncertainty regarding treatment for specific genotypes and prescription of restrictions regarding physical activity. This study explored what impacts physicians’ decision making with regard to treatment and recommendations for children and adolescents with LQTS. Semi-structured interviews were conducted with pediatric cardiologists who were currently treating this population. Several themes regarding physician decision making were identified: constant reevaluation of decisions, impact of years of experience/number of LQTS patients treated, differentiating from versus joining with other physicians, variations in recommending patient sports involvement and activity level, and physicians as …


Youth Treatment Adherence At A Rural Community Mental-Health Clinic, Asma S. Ali Jan 2013

Youth Treatment Adherence At A Rural Community Mental-Health Clinic, Asma S. Ali

PCOM Psychology Dissertations

This study examined the relationships between youth and adult psychopathology, and sociodemographic factors and treatment adherence for youth attending outpatient treatment at a rural community mental-health clinic. “Adherence” was defined as attending more than five sessions, while “non-adherence” was defined as attending fewer than or equal to five sessions. Results revealed no significant differences between youth adhering or not adhering to treatment depending on the relation of caregiver to youth or the mode of transportation taken to the clinic. Furthermore, caregiver and youth psychopathology and caregiver’s estimated travel time to the clinic did not predict treatment adherence. Incidentally, examination of …


A Single Case Study Of Cognitive Remediation Therapy With An Adolescent With Disordered Eating, Carol Lynn Galiano Jan 2013

A Single Case Study Of Cognitive Remediation Therapy With An Adolescent With Disordered Eating, Carol Lynn Galiano

PCOM Psychology Dissertations

Picky eating is currently not included in the diagnostic classification system DSM-IV TR as a distinct category of eating disorders in childhood. It can reach clinical significance requiring intervention when it results in chronic nutritional inadequacies and/or harmful impact on social development or family functioning. Studies have shown that patients with eating disorders have difficulties with executive functioning. These findings have been used to develop an intervention based on cognitive remediation therapy (CRT) which targets thinking skills and their role in the development and maintenance of an eating disorder. To further investigate, this study assessed the efficacy of an 8-week, …


A Study Of The Utilization Of Brief And Biblically Integrated Child Parent Relationship Therapy With Mothers From Christian Families And Their 11-14 Year Old Children, Valerie Waruszewski Jan 2013

A Study Of The Utilization Of Brief And Biblically Integrated Child Parent Relationship Therapy With Mothers From Christian Families And Their 11-14 Year Old Children, Valerie Waruszewski

Doctoral Dissertations and Projects

Twenty-six mothers and their 11-14 year old children participated in the Child Parent Relationship Therapy (CPRT). Although designed for elementary-aged children, CPRT was modified for pre-teens and biblically integrated worldview. An analysis of data obtained from the Parenting Relationship Questionnaire-CA (Kamphaus & Reynolds, 2009), Conflict Behavior Questionnaire-20 (Robin & Foster, 1989), and Inventory of Parent and Peer Attachment (Armsden & Greenberg, 1987) revealed meaningful trends in the decrease of frustration, levels of conflict, and negative communication within family systems. It is hoped that these findings will encourage additional research to help Christian mothers and therapists with an effective tool that …

Coker, Elizabeth Miller, Phyllis Sharps, Wendy G. Lane, Mahua Mandal, Kelli Hirsch, Donna M. Strobino, Wendy L. Bennett, Jacquelyn Campbell, Andrea Gielen

CRVAW Faculty Journal Articles

BACKGROUND: Intimate partner violence (IPV) is prevalent among adolescent and adult women, with significant physical, sexual, and mental health consequences. In 2011, the Institute of Medicine's Clinical Preventive Services for Women consensus report recommended universal screening for violence as a component of women's preventive services; this policy has been adopted by the Health Resources and Services Administration (HRSA). These policy developments require that effective clinic-based interventions be identified, easily implemented, and taken to scale.

METHODS: To foster dialogue about implementing effective interventions, we convened a symposium entitled "Responding to Violence Against Women: Emerging Evidence, Implementation Science, and Innovative Interventions," on …

Expanding The Basic Science Debate: The Role Of Physics Knowledge In Interpreting Clinical Findings., Mark Goldszmidt, John Paul Minda, Sarah L Devantier, Aimee L Skye, Nicole N Woods

Brain and Mind Institute Researchers' Publications

Current research suggests a role for biomedical knowledge in learning and retaining concepts related to medical diagnosis. However, learning may be influenced by other, non-biomedical knowledge. We explored this idea using an experimental design and examined the effects of causal knowledge on the learning, retention, and interpretation of medical information. Participants studied a handout about several respiratory disorders and how to interpret respiratory exam findings. The control group received the information in standard "textbook" format and the experimental group was presented with the same information as well as a causal explanation about how sound travels through lungs in both the …


Social Support And Youth Psychotherapy Outcomes: Examining Change Processes In Usual Care Settings, Robert Virgil Dindinger Jul 2012

Social Support And Youth Psychotherapy Outcomes: Examining Change Processes In Usual Care Settings, Robert Virgil Dindinger

Theses and Dissertations

A prominent need in youth psychotherapy literature includes the examination of factors related to improved psychotherapeutic outcomes within the context of "real world" clinical settings, where the practice of psychotherapy differs significantly from that in controlled clinical trials. In examining those factors related to improved outcomes in youth psychotherapy, variables related to social support are important to consider. The purpose of the present study was to evaluate youth perceptions of social support as a potential predictor of successful treatment outcomes in a traditional community outpatient treatment setting for youth. In addition, this study examined whether perceptions of social support predicted …


Supporting Utah's Parents In Preventing Adolescent Suicide: A Literature Review And Handouts For Utah's Youth Suicide Prevention Manual, Jennifer L. Whicker Jun 2012

Supporting Utah's Parents In Preventing Adolescent Suicide: A Literature Review And Handouts For Utah's Youth Suicide Prevention Manual, Jennifer L. Whicker

Theses and Dissertations

Suicide, a public health problem on a global scale, has become the focus in many domains across the United States. With the recent push to provide solutions to the adolescent suicide rate in the U.S., the school setting has become an important venue for prevention and intervention efforts. While there are many risk and protective factors, the majority of suicide completions are concurrent with psychiatric disorders among adolescents; as such, this is an area that warrants further investigation. Additionally, school resources are often overwhelmed by the magnitude of need among the student population; therefore, effective interventions must be identified that …


Deep Play, Urban Space, Adolescent Place: A Multi-Sited Study Of The Effects Of Settings On Adolescent Risk/Reward Behavior, Benjamin A. Shirtcliff May 2012

Deep Play, Urban Space, Adolescent Place: A Multi-Sited Study Of The Effects Of Settings On Adolescent Risk/Reward Behavior, Benjamin A. Shirtcliff

LSU New Orleans Theses and Dissertations

The extant literature on the play behavior of youth normalizes adolescent behavior in public space as transgressional, resistant, and in need of social control. The dissertation counters this trend by looking to see if physical qualities, peer effects, and neighborhood context of settings play a deeper role in youth behavior. The study documented urban context, peer effects, physical features, and play behavior across 21 urban settings in New Orleans. Unobtrusive observations employed a highly innovative technique based on YouTube videos and analyzed using hierarchical linear modeling. Coded observations of risk-taking and prosocial behavior demonstrated some stability in behavior amongst adolescents—“youth” …


Parental And Family Predictors Of Adolescent Weight Loss And Health Change In A Multidisciplinary Obesity Intervention, Jacqueline Woods May 2012

Parental And Family Predictors Of Adolescent Weight Loss And Health Change In A Multidisciplinary Obesity Intervention, Jacqueline Woods

Theses and Dissertations

The home environment, parental health attitudes, and parental diet and exercise behaviors have been associated with childhood obesity. The current study utilized a family systems framework to examine the effect of these variables on weight and health changes in a primarily Black sample of 530 parent-adolescent dyads enrolled in a multidisciplinary weight loss intervention. Parent-reported psychosocial variables and demographic information were used to test models predicting changes in adolescents’ body mass index, cholesterol, and percentage body fat over the first six months of the intervention. The effect of parent participation in a psycho-education parent group on adolescent health outcomes was …


Brains, Beads And Boulders: Trauma-Informed Sensory Interventions For Adolescents, Gini Christine Trotter May 2012

Brains, Beads And Boulders: Trauma-Informed Sensory Interventions For Adolescents, Gini Christine Trotter

Educational Specialist, 2009-2019

For beginning counselors there was minimal training in academic programs to address client experiences with trauma and the value of sensory interventions in treatment. The purpose of this literature review and compilation of adventure-based and creative arts interventions was to provide an understanding of trauma for adolescents from a neurobiological perspective, to provide assessment tools, a selection of sensory-based interventions for use within counseling sessions, and resources relevant to the beginning counselor. Steele and Kuban (2011) describe the experience of trauma as feeling completely unsafe and powerless. Interventions, then, should focus on repairing a sense of safety and power. To …


Multiple Peer Group Self-Identification And Adolescent Tobacco Use, C. Anderson Johnson, Juliana L. Fuqua, Peggy E. Gallaher, Jennifer B. Unger, Dennis R. Trinidad, Steve Sussman, Enrique Ortega May 2012

Multiple Peer Group Self-Identification And Adolescent Tobacco Use, C. Anderson Johnson, Juliana L. Fuqua, Peggy E. Gallaher, Jennifer B. Unger, Dennis R. Trinidad, Steve Sussman, Enrique Ortega

CGU Faculty Publications and Research

Associations between peer group self-identification and smoking were examined among 2,698 ethnically diverse middle school students in Los Angeles who self-identified with groups such as Rockers, Skaters, and Gamers. The sample was 47.1% male, 54.7% Latino, 25.4% Asian, 10.8% White, 9.1% Other ethnicity, and 59.3% children of immigrant parents. Multiple group self identification was common: 84% identified with two or more groups and 65% identified with three or more groups. Logistic regression analyses indicated that as students endorsed more high risk groups, the greater their risk of tobacco use. A classification tree analysis identified risk groups based on interactions among …


Latent Classes Of Self-Reported Adolescent Depression In A Clinical In-Patient Population, Jonathan F. Doti May 2012

Latent Classes Of Self-Reported Adolescent Depression In A Clinical In-Patient Population, Jonathan F. Doti

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The depressive disorders are among the most common mental health problems with substantial financial and quality-of-life costs. Depression has generated considerable debate as to the underlying structure/taxonomy and continues to be frequently debated. Adolescents who meet diagnostic criteria for major depressive disorder often experience anxiety (and vice versa). Therefore, understanding the underlying structure of depression as well as the co-occurrence of anxiety in a population of adolescents adds to our conceptual understanding of these disorders and facilitates treatment clarity.

This investigation sought to investigate the following research questions for adolescents’ self-reported symptoms of depression, and self-reported symptoms of depression and …


Unfakeable Facial Configurations Affect Strategic Choices In Trust Games With Or Without Information About Past Behavior, Constantin Rezlescu, Brad Duchaine, Christopher Y. Olivola, Nick Chater Mar 2012

Unfakeable Facial Configurations Affect Strategic Choices In Trust Games With Or Without Information About Past Behavior, Constantin Rezlescu, Brad Duchaine, Christopher Y. Olivola, Nick Chater

Dartmouth Scholarship

Background:

Many human interactions are built on trust, so widespread confidence in first impressions generally favors individuals with trustworthy-looking appearances. However, few studies have explicitly examined: 1) the contribution of unfakeable facial features to trust-based decisions, and 2) how these cues are integrated with information about past behavior.

Methodology/Principal Findings:

Using highly controlled stimuli and an improved experimental procedure, we show that unfakeable facial features associated with the appearance of trustworthiness attract higher investments in trust games. The facial trustworthiness premium is large for decisions based solely on faces, with trustworthy identities attracting 42% more money (Study 1), and remains …


General Motivation Domains & Behavioral Specificity Across Motivations, Justin B. Christensen, David C. Dollahite, Sam A. Hardy Mar 2012

General Motivation Domains & Behavioral Specificity Across Motivations, Justin B. Christensen, David C. Dollahite, Sam A. Hardy

FHSS Mentored Research Conference

The present study used Self-Determination Theory to explore adolescents' motivations to engage in prosocial behaviors (donating and volunteering) and abstain from health-risk behaviors (marijuana use and sexual intercourse). Pearson's r correlations evidenced general motivation schemes (prosocial and abstinence), suggesting that general prosocial motivation will prompt many prosocial behaviors while a general abstinence motivation will discourage many health risk behaviors. Multiple regression analysis, however, indicated that motivation is also behavior specific, meaning that specific behaviors are prompted by specific motivation. These findings help to broaden our understanding of adolescents by revealing two levels of motivation; behavioral and domain.


Rapid Perceptual Learning Of Noise-Vocoded Speech Requires Attention, Julia Jones Huyck, Ingrid Johnsrude Mar 2012

Rapid Perceptual Learning Of Noise-Vocoded Speech Requires Attention, Julia Jones Huyck, Ingrid Johnsrude

Brain and Mind Institute Researchers' Publications

Humans are able to adapt to unfamiliar forms of speech (such as accented, time-compressed, or noise-vocoded speech) quite rapidly. Can such perceptual learning occur when attention is directed away from the speech signal? Here, participants were simultaneously exposed to noise-vocoded sentences, auditory distractors, and visual distractors. One group attended to the speech, listening to each sentence and reporting what they heard. Two other groups attended to either the auditory or visual distractors, performing a target-detection task. Only the attend-speech group benefited from the exposure when subsequently reporting noise-vocoded sentences. Thus, attention to noise-vocoded speech appears necessary for learning.
