Theory Of Planned Behavior Constructs As Mediators Of Behavior Change Associated With A Brief Alcohol Intervention, Denise Servo Jan 2008

Theory Of Planned Behavior Constructs As Mediators Of Behavior Change Associated With A Brief Alcohol Intervention, Denise Servo

Open Access Theses & Dissertations

This study examined the Theory of Planned Behavior constructs (attitudes, subjective norms, perceived behavioral control [PBC], and behavioral intentions) as mediators of changes in alcohol consumption and alcohol-related problems in a longitudinal sample of 206 college students. The Brief Alcohol Screening and Intervention for College Students (BASICS) is a program designed to curb risky alcohol consumption and its related consequences among college students. Eligible students completed a baseline assessment battery at assessment and again six months after participating in BASICS. The AUDIT (Alcohol Use Disorders Identification Test) assessed alcohol consumption and the RAPI (Rutgers Alcohol Problem Inventory) assessed alcohol-related problems. …


An Exploration Of Satisfaction, Psychological Stress, And Readiness For Interprofessional Learning In Medical, Nursing, Allied Health, And Social Work Students In An Interprofessional Health Care Course, Anne M. Haskins Jan 2008

An Exploration Of Satisfaction, Psychological Stress, And Readiness For Interprofessional Learning In Medical, Nursing, Allied Health, And Social Work Students In An Interprofessional Health Care Course, Anne M. Haskins

Theses and Dissertations

Medical errors are a prominent problem in health care systems in many countries, including the U.S. One source of medical errors is communication and collaboration between health care team members. Many medical, nursing, and allied health care programs have implemented interprofessional health carecourses to improve communication between future team members. However, a dearth of literature on the effectiveness of interprofessional education and the variables that may influence its efficacy continues to persist.

This survey research explored medical, nursing, occupational therapy, physical therapy, and social work students' achievement of knowledge, psychologicalstress, and satisfaction in an interprofessional health care course. Ninety-six students …


Assignment Of Meaning In The Male Breast Cancer Experience: A Phenomenological Study, Marlys Joy Bohn Jan 2008

Assignment Of Meaning In The Male Breast Cancer Experience: A Phenomenological Study, Marlys Joy Bohn

Theses and Dissertations

The purpose of this phenomenological study was to gain an understanding of the lived experience of being a male diagnosed with breast cancer. With almost 200,000 cases of breast cancer diagnosed annually in the United States, a fact often overlooked is that approximately one percent of the newly-diagnosed patients are male. Because of their small numbers, however, very little is known about how males are affected by a diagnosis of breast cancer. In order to provide holistic nursing care to affected men and their families, it is important that nurses have an understanding of the male experience with breast cancer. …

Suicidal Ideation In College Students Varies Across Semesters: The Mediating Role Of Belongingness, Scott R. Braithwaite, Kimberly Van Orden, Tracy K. Witte, Lisa M. James, Yessenia Castro, Kathryn H. Gordon, Daniel L. Hollar, Thomas E. Joiner Jr.

Faculty Publications

The interpersonal–psychological theory of suicidal behavior (Joiner, 2005)proposes that the need to belong is fundamental; when met it can prevent suicide and when thwarted it can substantially increase the risk for suicide. We investigate one source of group-wide variation in belongingness among college students—changes in the social composition of college campuses across academic semesters—as an explanation for variation in suicidal ideation across the academic year.Our results indicate that in a sample of college students at a large southern state university (n=309), suicidal ideation varied across academic semesters, with high-est levels in summer compared to both spring and fall. Differences in …

Clinical Application Of Standardized Cognitive Assessment Using Fmri. Ii. Verbal Fluency, Mark D. Allen, Alina K. Fong Jan 2008

Clinical Application Of Standardized Cognitive Assessment Using Fmri. Ii. Verbal Fluency, Mark D. Allen, Alina K. Fong

Faculty Publications

In this study, we describe an fMRI version of the verbal fluency test. This is the second in a series of fMRI adaptations of classical neuropsychological tests, for which normative samples of functional activation have been collected from unimpaired control subjects and structured in a manner that makes individual patient evaluation possible in terms of familiar z-score distributions. This fMRI protocol is shown to have strong convergent validity with the FAS phonemic fluency test and to elicit activation patterns highly consistent with a large body of previous neuroimaging studies of verbal fluency. We also present a case study, in which …


Clinical Application Of Standardized Cognitive Assessment Using Fmri. I. Matrix Reasoning, Mark D. Allen, Alina K. Fong Jan 2008

Clinical Application Of Standardized Cognitive Assessment Using Fmri. I. Matrix Reasoning, Mark D. Allen, Alina K. Fong

Faculty Publications

Functional MRI is increasingly recognized for its potential as a powerful new tool in clinical neuropsychology. This is likely due to the fact that, with some degree of innovation, it is possible to convert practically any familiar cognitive test into one that can be performed in the MRI scanning environment. However, like any assessment approach, meaningful interpretation of fMRI data for the purpose of patient evaluation crucially requires normative data derived from a sample of unimpaired persons, against which individual patients may be compared. Currently, no such normative data are available for any fMRI-based cognitive testing protocol. In this paper, …

Health-Related Quality Of Life Of Patients Following Selected Types Of Lumbar Spinal Surgery: A Pilot Study, Karen L. Saban, Sue M. Penckofer, Ida Androwich, Fred B. Bryant

Psychology: Faculty Publications and Other Works

Background

Over 500,000 spinal surgeries are performed annually in the United States. Although pain relief and improved health-related quality of life (HRQOL) are expectations following lumbar spinal surgery, there is limited research regarding this experience from the individual's perspective. In addition, no studies have examined the HRQOL of persons who have had this surgery using a comprehensive approach. The intent of this study was to address this deficiency by an assessment of both the individual and environmental factors that impact perceived HRQOL using the Wilson and Cleary Model for Health-Related Quality of Life in persons who have undergone lumbar spinal …

Examining The Effects Of Fatigue On Decision-Making In Nursing: A Policy-Capturing Approach, Laura Mcclelland

All Dissertations

Some previous research has focused on better understanding factors that influence nurses' decision-making; however, previous research has not used policy-capturing as a methodology to examine the impact of fatigue on registered nurses' decision-making. The purpose of the current study was to examine whether the fatigue of working a 12-hour day shift influenced a sample of registered nurses' decision-making. Participants consisted of 69 registered nurses working a 12-hour day shift from 7 AM to 7 PM at a large southeastern hospital. The participants completed a general questionnaire and a policy-capturing questionnaire at the beginning and at the end of a 12-hour …


Women's Perceptions Of Parents, Peers, Romantic Partner And God As Predictive Of Symptoms Severity Among Women In Treatment For Eating Disorders At An Inpatient Facility, Samuel B. Tobler Dec 2007

Women's Perceptions Of Parents, Peers, Romantic Partner And God As Predictive Of Symptoms Severity Among Women In Treatment For Eating Disorders At An Inpatient Facility, Samuel B. Tobler

Theses and Dissertations

The present study examined whether perceptions of parents, peers, romantic partners and God were predictive of eating disorder symptom severity among women in treatment for eating disorders. The sample included 417 women (ages 12 to 56 years) at an inpatient treatment facility for eating disorders. Participants completed a battery of assessment measures at intake and discharge. Change scores were also computed on all measures. Measures included indices of eating disorder symptomology, parental relationships, peer relationships, romantic partner relationships, and religious well-being. Multiple regression analysis showed perceptions of peers and romantic partner to be significant predictors in all analyses; however perceptions …

The purpose of this study was to investigate the effects of being prompted to focus on self-talk versus bodily sensations on exercise intensity chosen by participants and level of enjoyment. One hundred and forty-two undergraduate psychology students ran on a treadmill for 20 minutes on two separate days, one week apart. One day they were asked to focus on their bodily sensations and on another day positive self-talk. The order of these assigned focuses was counterbalanced. Participant's current level of exercise activity (Stage of Change) was used as an independent variable. The dependent variables of interest were self-selected exercise intensity …


Gender, Attitudes, And Perceptions Of Workplace Incivility, Christopher C. Brady Dec 2007

Gender, Attitudes, And Perceptions Of Workplace Incivility, Christopher C. Brady

Masters Theses & Specialist Projects

The purpose of the present study was to examine perceptions of workplace incivility as a function of observers’ gender, observers’ gender-related attitudes, and the gender of the instigator and target of the mistreatment. The study included data from 102 (65% female, 90% white) participants from various occupations and backgrounds across the United States. Participants completed a web-based survey that consisted of scenarios of uncivil interactions, gender-attitudes, and various demographic information. Results suggest that observers’ gender and gender-related attitudes are important factors in how they perceive workplace incivility. Results also suggest that the gender of those involved in uncivil interactions is …


An Examination Of The Factors Of Influence On Rebellious Risky Behaviors In Adolescents, Audrey Roach Dec 2007

An Examination Of The Factors Of Influence On Rebellious Risky Behaviors In Adolescents, Audrey Roach

Masters Theses & Specialist Projects

Previous research indicates that the majority of today's adolescents are engaging in or have engaged in some type of rebellious risky behavior, such as consuming alcohol or using tobacco or other drugs (Haynie, 2003; Kann et al., 2000; Loper, 2000; Markey, Markey, & Tinsley, 2003; Patton, McMorris, Donath, & Catalano, 2004; Rickwood, 2005; Steinberg & Morris, 2001). In order to decrease levels of adolescent engagement in these rebellious behaviors, the factors of influence on these behaviors must be identified and understood. While studies in the past have focused on individual factors that influence adolescent involvement in these behaviors, the present …


An Examination Of The Role Of Anxiety And Obsessive-Compulsive Features In Muscle Dysmorphia Symptomatology, Christopher Chandler Dec 2007

An Examination Of The Role Of Anxiety And Obsessive-Compulsive Features In Muscle Dysmorphia Symptomatology, Christopher Chandler

Masters Theses & Specialist Projects

Although Muscle Dsymorphia (MD) has received more attention in recent years, it still lacks an official classification. The current study incorporates trait anxiety and obsessive-compulsive features into an etiological model of MD in the hopes of establishing them as reliable predictors of such MD symptomatology as drive for muscularity, social physique anxiety, and negative body attitude (self). This model was based upon previous research that has linked trait anxiety and obsessive-compulsive features to eating disorders (ED). In this model, it was predicted that trait anxiety and obsessive-compulsive features would predict overall MD symptomatology, drive for muscularity, social physique anxiety, and …


The Effects Of Domain Knowledge And Scene Content On Change Detection Using A Change Blindness Paradigm, Marianne T. Baskin Dec 2007

The Effects Of Domain Knowledge And Scene Content On Change Detection Using A Change Blindness Paradigm, Marianne T. Baskin

Master's Theses - Daytona Beach

This thesis was designed to determine how domain knowledge or scene content affects change detection. Twenty-four participants of medical professionals and non-medical professionals performed a change detection task using a flicker paradigm intended to be similar to saccadic movements or blinks. Each participant viewed 24 pictures on a computer screen, each picture flickering with a blank gray screen alternating between the original and modified version of the picture, and was asked to indicate when a change was detected by depressing a key. Twelve of the pictures were medical X-rays while the other 12 were everyday scenes. Reaction time, number of …

Therapists' Handling Of Secrets Between Partners In Couple Therapy, Michael Alan Jansen Dec 2007

Therapists' Handling Of Secrets Between Partners In Couple Therapy, Michael Alan Jansen

Dissertations

This study examines couple therapists' policies, procedures, and perspectives regarding secrets between partners in couple therapy. Handling secrets appropriately is necessary to avoid legal, ethical and therapeutic problems, especially when the secret involves contentious or potentially dangerous material such as infidelity, divorce, paternity, and HIV/AIDS infection. One hundred sixty randomly selected Clinical Members of the AAMFT participated in a 38-question researcher-generated mail survey. Data provided descriptive statistics and allowed for between-groups comparisons to explore for differences between therapists with regard to experience and several specific practices related to handling secrets. The study also examined whether courses in HIV/AIDS confidentiality law …


Application Of The Transtheoretical Model Of Change To Saving Behaviors Of College Students, Benjamin Franklin Cummings Dec 2007

Application Of The Transtheoretical Model Of Change To Saving Behaviors Of College Students, Benjamin Franklin Cummings

Undergraduate Honors Capstone Projects

Using the Transtheoretical Model (TTM) of change (Prochaska & Di Clemente, 1982) as a guide to analyze financial behavior, college students were asked a variety of questions about their financial situations. Recruited from undergraduate classes at Utah State University, 112 students took the online survey. Surprisingly, 44.4% of participants reported being in the Maintenance stage of the TTM, and 71.2% reported contributing at least monthly to some sort of savings or investment account. In terms of Financial Planning Personality Type (Lown, 2007), 46.3% of respondents were Planners and 23.1% were Savers. Though the study displays limitations, it begs further investigation …


The Relationship Between Childhood Bereavement And Adult Mental Health, Alicia Kimball Dec 2007

The Relationship Between Childhood Bereavement And Adult Mental Health, Alicia Kimball

Undergraduate Honors Capstone Projects

Bereavement, due to the loss of family and friends, affects approximately 3.7 million children per year in the United States. These losses can have lasting effects such as changed dynamics within a family, decreased academic performance, and poor physical and mental health that not only inhibit a child's ability to function normally but if not dealt with sufficiently can persist into adulthood.

The primary purpose of this study was to determine if individuals who experienced a loss in childhood exhibit more mental health problems in adulthood than those who did not. A survey was administered to 209 college students requesting …


Exercise Makes You Feel Good, But Does Feeling Good Make You Exercise?: An Examination Of Obese Dieters, Robert A. Carels, Carissa Coit, Kathleen Young, Bonnie Berger Dec 2007

Exercise Makes You Feel Good, But Does Feeling Good Make You Exercise?: An Examination Of Obese Dieters, Robert A. Carels, Carissa Coit, Kathleen Young, Bonnie Berger

Psychology Faculty Publications

Whereas exercise-induced mood enhancement has been well documented, the relationship between mood and exercise participation is less well understood. Mood states influence evaluative judgments that could plausibly influence a decision to exercise. Further, most exercise-mood research is limited to normal weight adults in response to a single exercise session. The current investigation examines the influence of (a) morning mood on exercise, (b) exercise intensity/duration on mood enhancement, and (c) daily change in mood on exercise days compared with nonexercise days in obese behavioral weight loss program (BWLP) participants. Participants (N=36) recorded morning, evening, and pre- and postexercise mood, as well …


Neuropsychopharmacological Investigations Of Mdma/Cocaine Combinations, John J. Panos Dec 2007

Neuropsychopharmacological Investigations Of Mdma/Cocaine Combinations, John J. Panos

Masters Theses

Despite the popularity of polydrug abuse among recreational MDMA users, relatively few controlled experimental studies have documented the neurobehavioral effects of MDMA in combination with other abused substances. In this study, the neurochemical and behavioral effects of MD MA/cocaine combinations were assessed using in vivo microdialysis with simultaneous measurement of locomotor activity (LMA). Rats were administered cocaine (10 mg/kg or 20 mg/kg, IP), MDMA (1.5 mg/kg or 3.0 mg/kg, IP) or combinations of cocaine and MDMA during microdialysis experiments. Microdialysis samples were collected every 30 min for three hours prior to drug injections. Following drug administration, six additional 30 min …


Impact Of Treatment On Body Image In Obese Children, Danusia Nedilskyj Dec 2007

Impact Of Treatment On Body Image In Obese Children, Danusia Nedilskyj

Loma Linda University Electronic Theses, Dissertations & Projects

Pediatric obesity is a national epidemic with serious medical implications. Currently, almost one-quarter of children in the United States are overweight. Without intervention, children typically are unable to outgrow obesity and the majority of overweight children become overweight adults. Further, childhood obesity results in numerous psychological consequences, including dissatisfaction with body image. Thus, prevention and treatment of childhood obesity are crucial to protect children from the resultant physical and psychological risk factors which will impact their future health. The Growing Fit Program is a pediatric clinic in the Department of Pediatrics at Loma Linda University, which seeks to serve the …


Executive Functioning And Memory Performance In Adhd And Asperger's Syndrome, Kristi A. Walen Dec 2007

Executive Functioning And Memory Performance In Adhd And Asperger's Syndrome, Kristi A. Walen

Theses and Dissertations

The diagnosis of ADHD requires the exclusionary criteria for any Pervasive Developmental Disorder (PDD), making it impossible to have comorbid disorders. This study investigated executive function and memory differences between 11 children with Asperger’s syndrome, 13 children with ADHD, and 36 controls, all ranging in age from 7-16 years. Executive function was assessed using Conner’s Continuous Performance Test (CPT), Wisconsin Card Sorting Task (WCST), Tower of London Task (TOL), Trail Making Test, Rey-Osterrieth Complex Figure (ROCF), Grooved Pegboard Test, and the Controlled Oral Word Association Test (COWAT). Memory was assessed using a subtest from the Wide Range Assessment of Memory …

A Study Of Intake And Assessment In Solution-Focused Brief Therapy, Christopher J. Richmond Dec 2007

A Study Of Intake And Assessment In Solution-Focused Brief Therapy, Christopher J. Richmond

Dissertations

The purpose of this study was to compare clients' assessment of two different counseling intake procedures used by clinicians. This study compared a Solution-Focused Brief Therapy (SFBT) intake intervention with an intake intervention constructed from the Structured Clinical Interview for the DSM-IV Axis I Disorders (SCID-I). The SCID-I is one of the most widely used diagnostic interviews and reflects a "gold standard" in formulating accurate diagnoses. The SFBTintake intervention developed for this study stands in stark contrast to the SCID-I and its primary objective, evaluation of the problem. SFBT is a strength-based model that maintains a positive and future-oriented focus. …


The Effects Of Acute Nicotine Abstinence On Vigilance And Verbal Memory In Non-Diagnosed Smokers, David W. Ayer Dec 2007

The Effects Of Acute Nicotine Abstinence On Vigilance And Verbal Memory In Non-Diagnosed Smokers, David W. Ayer

Dissertations

Research has shown a differential prevalence of smoking in the schizophrenic population compared to other psychiatric and non-diagnosed populations. The three most commonly investigated reasons for this differential prevalence in schizophrenics are: the self-medication hypothesis, side effects hypothesis, and sociological hypothesis. The self-medication hypothesis which proposes that schizophrenics smoke at a higher rate to ameliorate cognitive deficits is the most substantiated by the research. Of current interest is the possible role of nicotine in improving performance on vigilance and verbal memory, the two areas shown to be most related to impaired social functioning in schizophrenics. It is difficult to make …
