Mental Health Of Incarcerated Juveniles In Nevada: Final Report, Nevada Institute For Children's Rerearch And Policy, University Of Nevada, Las Vegas, Jennifer Petsonius, Denise Tanata, Michelle Chino Dr Dec 2003

Mental Health Of Incarcerated Juveniles In Nevada: Final Report, Nevada Institute For Children's Rerearch And Policy, University Of Nevada, Las Vegas, Jennifer Petsonius, Denise Tanata, Michelle Chino Dr

Nevada Institute for Children's Research and Policy Reports

The prevalence of mental health problems in the juvenile offender population is substantially higher than that of the general population (Cocozza & Skowyra, 2000). Studies estimate that one in five juvenile offenders has serious mental health problems, which is nearly twice the rate of occurrence of mental illness in children and adults in the general population (NMHA Fact Sheet #l). However, there have been several methodological problems encountered in previous research. These include the use of inconsistent definitions and measurements of mental illness; the use of biased, nonrandom samples, a reliance on retrospective case report data, and the use of …


Barriers To Lesbian Health Care, Paula Bowles Dec 2003

Barriers To Lesbian Health Care, Paula Bowles

Masters Theses & Specialist Projects

The primary purpose of this research was to examine a sample of sixteen lesbian women regarding the barriers to lesbian health-care. From this information several interpretive findings regarding lesbian health-care are made. Data were gathered via indepth interviews with each individual lesbian. The data suggest that most lesbian women do not reveal their sexual orientation to their primary-care physician for fear of reprisal. Most of the women interviewed do feel they receive adequate health-care from their physician. The women who participated in this project did so confidentially and were assigned pseudonyms. They were asked questions on a variety of topics, …


Resiliency Factors Related To Substance Use/Resistance: Perceptions Of Native Adolescents Of The Southwest, Margaret A. Waller, Scott K. Okamoto, Bart Miles, Donna E. Hurdle Dec 2003

Resiliency Factors Related To Substance Use/Resistance: Perceptions Of Native Adolescents Of The Southwest, Margaret A. Waller, Scott K. Okamoto, Bart Miles, Donna E. Hurdle

The Journal of Sociology & Social Welfare

This exploratory, qualitative study examined risk and protective factors influencing drug and alcohol use and/or resistance of Native youth in the Southwest. Thirty-two Native middle school students participated in 10 focus groups that explored their experiences with alcohol and drugs in their school and reservation communities. The findings indicate a complex interaction of both risk and protective factors related to substance use. Respondents' cousins and siblings, in particular, played a key role in their decisions to use or resist drugs. Implications for social work practice are discussed.

The Relationship Between Childbirth Experience And Psychological Functioning In The Postpartum Period, Dena Dian Daniel

Student Dissertations & Theses

The purpose of this research is to examine the relationships between the mother's perception of the birth experience, symptoms of the post-traumatic stress, and symptoms of postpartum depression. Sixty-seven participants ranging from 17 to 40 years of age completed a self-report questionnaire containing items from three instruments including the Perception of Birth Scale, the Edinburgh Postnatal Depression Scale, and the Davidson Trauma Scale. The findings reveal a more negative perception of the birth experience is significantly related to a greater frequency and/or. severity of. post- traumatic stress and postpartum depression symptoms following childbirth., These findings support the conclusion that an …


Amygdala Hyperreactivity In Borderline Personality Disorder: Implications For Emotional Dysregulation, Nelson H. Donegan, Charles A. Sanislow, Hilary P. Blumberg, Robert K. Fulbright, Cheryl Lacadie, Pawel Skudlarski, John C. Gore, Ingrid R. Olson, Thomas H. Mcglashan, Bruce E. Wexler Nov 2003

Amygdala Hyperreactivity In Borderline Personality Disorder: Implications For Emotional Dysregulation, Nelson H. Donegan, Charles A. Sanislow, Hilary P. Blumberg, Robert K. Fulbright, Cheryl Lacadie, Pawel Skudlarski, John C. Gore, Ingrid R. Olson, Thomas H. Mcglashan, Bruce E. Wexler

Charles A. Sanislow, Ph.D.

BACKGROUND: Disturbed interpersonal relations and emotional dysregulation are fundamental aspects of borderline personality disorder (BPD). The amygdala plays important roles in modulating vigilance and generating negative emotional states and is often abnormally reactive in disorders of mood and emotion. The aim of this study was to assess amygdala reactivity in BPD patients relative to normal control subjects. We hypothesized that amygdala hyperreactivity contributes to hypervigilance, emotional dysregulation, and disturbed interpersonal relations in BPD.

METHODS: Using functional magnetic resonance imaging, we examined neural responses to 20-sec blocks of neutral, happy, sad, and fearful facial expression (or a fixation point) in 15 …

Clinical Features And Impairment In Women With Borderline Personality Disorder (Bpd) With Post-Traumatic Stress Disorder (Ptsd), Bpd Without Ptsd, And Other Personality Disorders With Ptsd, Caron Zlotnick, Dawn M. Johnson, Shirley Yen, Cynthia Battle, Charles A. Sanislow, Andrew E. Skodol, Carlos M. Grilo, Thomas H. Mcglashan, John G. Gunderson, Donna S. Bender, Mary C. Zanarini, M. Tracie Shea

Charles A. Sanislow, Ph.D.

The aims of this study were to examine differences in clinical features, impairment, and types of childhood traumas among women with borderline personality disorder (BPD), women with BPD and posttraumatic stress disorder (PTSD), and those with other personality disorders and PTSD. Using baseline data from the Collaborative Longitudinal Study of Personality Disorders, 186 women were divided into 3 groups (BPD+PTSD, BPD, PTSD), based on structured diagnostic interviews for Axis I and Axis II disorders and compared on selected clinical variables. The additional diagnosis of PTSD in borderline women did not significantly increase the degree of borderline pathology and psychiatric morbidity …


Client Commitment Language During Motivational Interviewing Predicts Drug Use Outcomes, Paul Amrhein, William R. Miller, Carolina Yahne, Michael Palmer, Laura Fulcher Oct 2003

Client Commitment Language During Motivational Interviewing Predicts Drug Use Outcomes, Paul Amrhein, William R. Miller, Carolina Yahne, Michael Palmer, Laura Fulcher

Department of Psychology Faculty Scholarship and Creative Works

Client language from a motivational interview (MI) and drug use outcome were investigated. Interview videotapes of 84 drug abusers were coded for frequency and strength of utterances expressing commitment, desire, ability, need, readiness, and reasons to change or maintain their habit. Cluster analysis of proportion days abstinent (PDA) revealed 3 groups: high PDA at intake and follow-up (3, 6, 9, 12 months; maintainers); low intake PDA/high follow-up PDA (changers); and low intake PDA/low to moderate follow-up PDA (stragglers). Distinct group patterns emerged for commitment strength (CS) during MI. Clients dishonest in checklist self-report exhibited CS similar to stragglers. CS for …


Clergy Sexual Abuse And The Catholic Church: What Do We Know And Where Do We Need To Go?, Thomas G. Plante Oct 2003

Clergy Sexual Abuse And The Catholic Church: What Do We Know And Where Do We Need To Go?, Thomas G. Plante

Psychology

Few recent topics have received the kind of media attention, heated debate, and discussion than the topic of sex-offending clergy, their victims, and supervisors. It is a story about too many bishops (and priests) behaving badly when they are purported to be the moral, religious, and ethical leaders of society. It is a remarkable story. However, it is a complex story that has had little scholarship and discourse driven by thoughtfulness, civility, and reason.


Intensive Care Medical Procedure : Ptsd Symptoms In Children, Ludmila Zaytsev Sep 2003

Intensive Care Medical Procedure : Ptsd Symptoms In Children, Ludmila Zaytsev

Loma Linda University Electronic Theses, Dissertations & Projects

Studies indicate that medical procedures may cause post-traumatic stress (PTS) symptoms (fear, avoidance, sleep disturbances, irritability, concentration difficulties. hypervigilance). It has been suggested that administration of midazolam hydrochloride, a sedative/amnesic medication commonly used in the Pediatric Intensive Care Units (PICU), may help decrease if not prevent the development of PTS symptoms. This study examined if PTS symptoms were related to procedural invasiveness (PI) and whether midazolam had a moderating effect on the development and intensity of PTS symptoms in children. English-speaking children ages 8-16 (N=20) who had been in the PICU for at least 3 days were recruited at Loma …


Validation Of A Serotonin Checklist In A Parkinson’S Disease Population, Kelly Diane Darby-Holder Sep 2003

Validation Of A Serotonin Checklist In A Parkinson’S Disease Population, Kelly Diane Darby-Holder

Loma Linda University Electronic Theses, Dissertations & Projects

Although the distinctive pathological marker of Parkinson’s Disease is the progressive death of neurons that produce dopamine, there are also alterations in the production of quantities of other neurotransmitters, such as norepinephrine and serotonin that contribute to the disease. Parkinson’s Disease (PD) can be divided into two distinct classes based on the manifestation of motor symptoms, Type A and Type B Parkinson’s Disease. Type B PD patients often manifest symptoms in which serotonin deficiency plays an important role, which often includes a history of depression. Within the brain and spinal cord serotonin has wide spread projections, acting as an important …


Radiation Effects On Dopamine-Mediated Prepulse Inhibition In The C57bl/6 Mouse, Cara Nicole Zuccarelli Miller Sep 2003

Radiation Effects On Dopamine-Mediated Prepulse Inhibition In The C57bl/6 Mouse, Cara Nicole Zuccarelli Miller

Loma Linda University Electronic Theses, Dissertations & Projects

This study examined the effects of proton and gamma radiation on a dopamine-dependent sensory gating mechanism: prepulse inhibition of the startle reflex. The purpose of this research was to describe potential hazards of proton radiation to the central nervous system in long-term space fight and for proton therapy patients. Results from previous research indicate that startle behavior is modified by proton and iron radiation. Forty-eight 10-½ week old, male C57BL/6 mice were used to characterize the optimal parameters for the model (prepulse duration, probe duration, and stimulus-onset-asynchrony). Three hundred and fifty two mice were used to characterize the time course …


The Psychological Characteristics Of Obese Children, Thomas Taylor Mitchell Sep 2003

The Psychological Characteristics Of Obese Children, Thomas Taylor Mitchell

Loma Linda University Electronic Theses, Dissertations & Projects

Several studies along with the surgeon general of the United States have identified obesity as a national health issue. Research indicates that adult obesity treatment has relatively poor long-term effects. Consequently increased attention has been given to addressing obesity in children. This focus is particularly vital due to the fact that children are one of the populations showing the most rapid increase in overweight and obesity. The purpose of this study was to identify the some of the unique psychological characteristics of obese children by analyzing the intake data of children and adolescents attending the Loma Linda University Growing Fit …


The Representation Of Four Personality Disorders By The Schedule For Nonadaptive And Adaptive Personality Dimensional Model Of Personality, Leslie C. Morey, Megan B. Warner, M. Tracie Shea, John G. Gunderson, Charles A. Sanislow, Carlos M. Grilo, Andrew E. Skodol, Thomas H. Mcglashan Aug 2003

The Representation Of Four Personality Disorders By The Schedule For Nonadaptive And Adaptive Personality Dimensional Model Of Personality, Leslie C. Morey, Megan B. Warner, M. Tracie Shea, John G. Gunderson, Charles A. Sanislow, Carlos M. Grilo, Andrew E. Skodol, Thomas H. Mcglashan

Charles A. Sanislow, Ph.D.

This study examined the relationships of the Schedule for Nonadaptive and Adaptive Personality (SNAP) model of personality to 4 targeted personality disorders (PDs) in a large multisite sample of patients. Data were examined from 529 patients, who were assigned 1 of 5 primary diagnoses: borderline, schizotypal, avoidant, and obsessive–compulsive PDs and major depression without PD. Patients were administered the SNAP questionnaire and results were compared among diagnostic groups and between patient groups and nonclinical norms. Results indicated that the dimensions of the model appear to have considerable promise in differentiating normal from abnormal personality, particularly in the propensity of individuals …


Time Course Of Loudness Recalibration: Implications For Loudness Enhancement, Yoav Arieh, Lawrence E. Marks Aug 2003

Time Course Of Loudness Recalibration: Implications For Loudness Enhancement, Yoav Arieh, Lawrence E. Marks

Department of Psychology Faculty Scholarship and Creative Works

Loudness recalibration, the effect of a relatively loud 2500-Hz recalibrating tone on the loudness of a relatively soft 2500-Hz target tone, was measured as a function of the interstimulus interval (ISI) between them. The loudness of the target tone, assessed by a 500-Hz comparison tone, declined when the ISI equaled or exceeded about 200 ms and leveled off at an ISI of about 700 ms. Notably, the target tone’s loudness did not change significantly at very short ISIs (<150 ms). The latter result is incompatible with the literature reporting loudness enhancement in this time window but is compatible with the suggestion made by Scharf, Buus, and Nieder [J. Acoust. Soc. Am. 112, 807–810 (2002)] that early measurements of enhancement were contaminated by the influence of the recalibrating tone on the comparison …


The Effect Of Task Versus Ego Oriented Feedback On Exercise Enjoyment, Marc Fields Aug 2003

The Effect Of Task Versus Ego Oriented Feedback On Exercise Enjoyment, Marc Fields

Masters Theses & Specialist Projects

Intrinsic motivation has been shown to be a very important factor in exercise adherence. Research has found that factors such as exercise intensity, social feedback, goal orientation and perceived climate can affect intrinsic motivation. The purpose of this study was to assess situational goal orientation, specifically whether individuals in a task induced condition or ego induced condition would report different levels of intrinsic motivation (i.e., enjoyment, tension, effort and competence during exercise). Participants (N= 114) rode on an exercise bike for 24 minutes at a moderate intensity. A MANCOVA factorial design was used to examine differences in intrinsic motivation. The …


Effects Of Perceived Costs And Rewards On Motivation And Retention Of Rape Crisis Center Volunteers, Amanda Grissom Aug 2003

Effects Of Perceived Costs And Rewards On Motivation And Retention Of Rape Crisis Center Volunteers, Amanda Grissom

Masters Theses & Specialist Projects

The purpose of this study was to obtain information that may assist Rape Crisis Center (RCC) volunteer coordinators and executive directors in the recruitment and retention of volunteers. The major hypotheses guiding this study are as follows: (a) the reasons that initially motivated volunteers to volunteer at the RCC will be the same as their reasons for why they are continuing to volunteer at the RCC and (b) volunteers at RCCs continue to volunteer because the perceived costs of volunteering do not exceed the perceived rewards of volunteering. Using a modified version of Black's (1989) questionnaire, respondents were asked to …


Axis I And Ii Disorders As Predictors Of Prospective Suicide Attempts: Findings From The Collaborative Longitudinal Personality Disorders Study, Shirley Yen, M. Tracie Shea, Maria Pagano, Charles A. Sanislow, Carlos M. Grilo, Thomas H. Mcglashan, Andrew E. Skodol, Donna S. Bender, Mary C. Zanarini, John G. Gunderson, Leslie C. Morey Jul 2003

Axis I And Ii Disorders As Predictors Of Prospective Suicide Attempts: Findings From The Collaborative Longitudinal Personality Disorders Study, Shirley Yen, M. Tracie Shea, Maria Pagano, Charles A. Sanislow, Carlos M. Grilo, Thomas H. Mcglashan, Andrew E. Skodol, Donna S. Bender, Mary C. Zanarini, John G. Gunderson, Leslie C. Morey

Charles A. Sanislow, Ph.D.

This study examined diagnostic predictors of prospectively observed suicide attempts in a personality disorder (PD) sample. During 2 years of follow-up, 58 participants (9%) reported at least 1 definitive suicide attempt. Predictors that were examined include 4 PD diagnoses and selected Axis I diagnoses (baseline and course). Multivariate logistic regression analyses indicated that baseline borderline personality disorder (BPD) and drug use disorders significantly predicted prospective suicide attempts. Controlling for baseline BPD diagnosis, proportional hazards analyses showed that worsening in the course of major depressive disorder (MDD) and of substance use disorders in the month preceding the attempt were also significant …


Gaze-Centered Updating Of Visual Space In Human Parietal Cortex., W Pieter Medendorp, Herbert C Goltz, Tutis Vilis, J Douglas Crawford Jul 2003

Gaze-Centered Updating Of Visual Space In Human Parietal Cortex., W Pieter Medendorp, Herbert C Goltz, Tutis Vilis, J Douglas Crawford

Brain and Mind Institute Researchers' Publications

Single-unit recordings have identified a region in the posterior parietal cortex (PPC) of the monkey that represents and updates visual space in a gaze-centered frame. Here, using event-related functional magnetic resonance imaging, we identified an analogous bilateral region in the human PPC that shows contralateral topography for memory-guided eye movements and arm movements. Furthermore, when eye movements reversed the remembered horizontal target location relative to the gaze fixation point, this PPC region exchanged activity across the two cortical lobules. This shows that the human PPC dynamically updates the spatial goals for action in a gaze-centered frame.

Psychosocial Stress And Cervical Neoplasia Risk, Ann L. Coker, Sharon M. Bond, Margaret M. Madeleine, Kathryn J. Luchok, Lucia Pirisi

CRVAW Faculty Journal Articles

OBJECTIVE: We assessed the association between psychosocial stress and preinvasive cervical neoplasia development controlling for HR-HPV infection.

METHODS: This case-control study enrolled low-income women receiving family planning services at health department clinics. There were 59 cases with biopsy confirmed HSIL and 163 with low-grade SIL and 160 controls with normal cervical cytology. A modified SLE scale was used to measure stressful events and the perceived impact of the event in the prior 5 years. Unconditional logistic regression was used to assess SIL risk and stressful events scores and by subscales.

RESULTS: After adjusting for age, HR-HPV infection, and lifetime number …


The Lateral Occipital Complex Subserves The Perceptual Persistence Of Motion-Defined Groupings., Susanne Ferber, G Keith Humphrey, Tutis Vilis Jul 2003

The Lateral Occipital Complex Subserves The Perceptual Persistence Of Motion-Defined Groupings., Susanne Ferber, G Keith Humphrey, Tutis Vilis

Brain and Mind Institute Researchers' Publications

How are the bits and pieces of retinal information assembled and integrated to form the coherent objects that we see? One long-established principle is that elements that move as a group are linked together. For instance a fragmented line-drawing of an object, placed on a background of randomly distributed short lines, can be impossible to see. But if the object moves relative to the background, its shape is instantly recognized. Even after the motion stops, the percept of the object persists briefly before it fades into the background of random lines. Where in the brain does the percept of the …


A Comparison Of Symptom Severity Between University Counseling Center And Community Mental Health Center Clients, Joshua Gunn Jul 2003

A Comparison Of Symptom Severity Between University Counseling Center And Community Mental Health Center Clients, Joshua Gunn

Masters Theses & Specialist Projects

The present study compares presenting levels of psychological distress at a university counseling center and a community mental health center. The Brief Symptom Inventory (BSI) was completed by clients at intake, and the results were subjected to statistical analysis. A significant difference was found between the two service units on the Global Symptom Index and all nine scales of the BSI. There were no gender differences in overall levels of psychological distress; however, a difference was found on the interpersonal hostility scale. Implications of the study, as well as limitations and suggestions for future research, are discussed.


Neural Correlates Of Memories Of Abandonment In Women With And Without Borderline Personality Disorder, Christian G. Schmahl, Bernet M. Elzinga, Eric Vermetten, Charles A. Sanislow, Thomas H. Mcglashan, J. Douglas Bremner Jun 2003

Neural Correlates Of Memories Of Abandonment In Women With And Without Borderline Personality Disorder, Christian G. Schmahl, Bernet M. Elzinga, Eric Vermetten, Charles A. Sanislow, Thomas H. Mcglashan, J. Douglas Bremner

Charles A. Sanislow, Ph.D.

BACKGROUND: Borderline personality disorder (BPD) is a common psychiatric disorder that is often linked to early stressors. One particularly salient feature of the disorder is fear of abandonment. This pilot study was conducted to measure neural correlates of memories of abandonment in women with and without BPD.

METHODS: Twenty women with a history of childhood sexual abuse underwent measurement of brain blood flow with positron emission tomography imaging while they listened to scripts describing neutral and personal abandonment events. Brain blood flow during exposure to abandonment and neutral scripts was compared among women with and without BPD.

RESULTS: Memories of …

Gender Differences In Borderline Personality Disorder: Findings From The Collaborative Longitudinal Personality Disorders Study, Dawn M. Johnson, M. Tracie Shea, Shirley Yen, Cynthia L. Battle, Caron Zlotnick, Charles A. Sanislow, Carlos M. Grilo, Andrew E. Skodol, Donna S. Bender, Thomas H. Mcglashan, John G. Gunderson, Mary C. Zanarini

Charles A. Sanislow, Ph.D.

A majority of the literature on borderline personality disorder (BPD) focuses on its occurrence in women or does not specifically assess for gender differences in clinical presentations. Some studies report that men with BPD may be more likely to be diagnosed with substance use disorders, as well as paranoid, passive-aggressive, narcissistic, sadistic, and antisocial personality disorders (PDs). Additionally, women with BPD appear to be more likely to report histories of adult physical and sexual abuse and to meet diagnostic criteria for post-traumatic stress disorder (PTSD) and eating disorders. The purpose of the present study was to further examine gender differences …

His talk primarily involves general comments and observations about the events of Bloody Sunday, sectarian conflicts in general, and values statements from Bradley offered in response to student questions about the conflict in Northern Ireland. He continues to talk about the White Oak Center in Donegal, which is a residential treatment center that in this account it heavily concerned with treating alcohol abuse. The tape shifts to talk about Bradley's work treating trauma experiences related to the Troubles. He began working in the Catholic community but then was asked to work …


Recalibrating The Auditory System: A Speed–Accuracy Analysis Of Intensity Perception, Yoav Arieh, Lawrence E. Marks Jun 2003

Recalibrating The Auditory System: A Speed–Accuracy Analysis Of Intensity Perception, Yoav Arieh, Lawrence E. Marks

Department of Psychology Faculty Scholarship and Creative Works

Recalibration in loudness perception refers to an adaptation-like change in relative responsiveness to auditory signals of different sound frequencies. Listening to relatively weak tones at one frequency and stronger tones at another make the latter appear softer. The authors showed recalibration not only in magnitude estimates of loudness but also in simple response times (RTs) and choice RTs. RTs depend on the sound intensity and may serve as surrogates for loudness. Most important, the speeded classification paradigm also provided measures of errors. RTs and errors can serve jointly to distinguish changes in sensitivity from changes in response criterion. The changes …


School Functioning And Violent Behavior Among Young Adolescents: A Contextual Analysis, Amanda Birnbaum, Leslie A. Lytle, Peter J. Hannan, David M. Murray, Cheryl L. Perry, Jean L. Foster Jun 2003

School Functioning And Violent Behavior Among Young Adolescents: A Contextual Analysis, Amanda Birnbaum, Leslie A. Lytle, Peter J. Hannan, David M. Murray, Cheryl L. Perry, Jean L. Foster

Department of Public Health Scholarship and Creative Works

This paper examines associations between overall school functioning and the frequency of violent behaviors among young adolescents (ages 10–14). The sample included 16 middle schools participating in an unrelated intervention study (on nutrition) in Minneapolis, Minnesota. A School Functioning Index developed to characterize schools’ overall stability, performance, and demographics was constructed using data from public archives and school administrator surveys. Data on violent behaviors and other variables were collected in student surveys in fall 1998 and spring 1999. We used multilevel modeling to assess the effect of school functioning on violent behavior after adjusting for known individual-level covariates of violent …


Cultural And Psychological Influences On Diabetic Adherence, Keikilani Mcmillin-Williams Jun 2003

Cultural And Psychological Influences On Diabetic Adherence, Keikilani Mcmillin-Williams

Loma Linda University Electronic Theses, Dissertations & Projects

Diabetes mellitus is a serious disease that poses a particular healthcare challenge because progression is considered controllable (Cox, et al, 1985; Vinicor, et al, 1996) yet treatment adherence, and thus outcome, is very poor (Gonder-Frederick, Cox, & Ritterband, 2002; Goodall, 1991). Culture is a lethal risk factor for diabetic contraction and treatment maintenance. Latinos within the United States are two-to-three times more likely to develop complications and die than non-Latinos (Haffner et al, 1996; Rubin, Peyrot, & Saudek, 1991) and are less likely to adhere to treatment (Lipton, Losey, Giachello, Mendez, & Girotti, 1998). Efforts to eliminate health disparities have …


Effects Of Moral Sensitivity And Moral Climate On Moral Reasoning, Marita Louise Mahoney Jun 2003

Effects Of Moral Sensitivity And Moral Climate On Moral Reasoning, Marita Louise Mahoney

Loma Linda University Electronic Theses, Dissertations & Projects

As healthcare professionals, psychology students and psychologists are expected to behave ethically and morally. It is assumed that moral and ethical reasoning in psychology students develops through exposure to ethical dilemmas within ethics classes and during clinical training experiences. Rest's Four Component Model of Moral Behavior, a neo-Kohlbergian approach to understanding moral development, posits an interaction of Moral Sensitivity, Moral Motivation, Moral Reasoning and Moral Character. Moral sensitivity, or awareness of a moral dilemma, is posited to cue the moral reasoning process, though little is known about how the training environment can facilitate or hamper such developments. Fifty".'two psychology-graduate students …


An Evaluation Of Methylphenidate Preference In Adults Diagnosed With Attention-Deficit/Hyperactivity Disorder, Emily Kathleen Macdonald Jun 2003

An Evaluation Of Methylphenidate Preference In Adults Diagnosed With Attention-Deficit/Hyperactivity Disorder, Emily Kathleen Macdonald

Dissertations

Methylphenidate (MPH) is widely used in the treatment of ADHD, and is associated with positive effects across a wide range of domains. In spite of the clinical effectiveness of MPH, concern has arisen with respect to its abuse potential. The present study examined the reinforcing effects and participant-rated effects of MPH in adults diagnosed with ADHD. Participants included 10 volunteers (ages 18-22) diagnosed with ADHD who were receiving MPH treatment. The reinforcing effects were assessed using a double-blind choice procedure with 4 sampling and 8 choice sessions. During sampling sessions, participants completed a self-report questionnaire before receiving either placebo or …
