Implementation Of The 2009 Cacrep Standards Addiction Competencies, Tiffany K. Lee

Dissertations

Addiction issues have been and continue to be significant problems affecting the United States. Over the past few decades, substantial scholarly attention has been paid to the lack of addictions training in the counseling profession. The purposes of this mixed-method study were to examine the current status of addiction training among institutions that offer counselor education programs accredited by the Council for Accreditation of Counseling and Related Educational Programs (CACREP) and determine how institutions plan to integrate the addiction-related competencies outlined in the 2009 CACREP standards.

The quantitative data were obtained from a 15-item online survey completed by 74 CACREP ...

Students Of Indian Heritage And United States Citizen Students' Adaptation Of College, Opinions About Mental Illness And Attitudes Toward Seeking Professional Counseling Help, Margaret Omotola Ajayi-Nabors

Dissertations

The present study replicated Baysden's (2002) multi-component model and tested its generalizability on a homogeneous demographic group. This study compared international college students from India (n 0 244) and U.S. student participants (n 0 393) on their adaptation to college, their opinions about mental illness, and their attitudes regarding their professional psychological help-seeking behavior. A structural regression model was utilized to examine if student origin influenced opinions about mental illness, student adaptation to college, and attitudes towards seeking professional psychological help. /// The findings of this project supported Baysden's (2002) multi-component model to understanding international students' use of ...


A Qualitative Study Of The Lived Experiences Of Adults With African American And Korean Heritages, Elizabeth Sue Bradshaw Jan 2011

A Qualitative Study Of The Lived Experiences Of Adults With African American And Korean Heritages, Elizabeth Sue Bradshaw

Dissertations

Scholarship on biracial persons has been primarily focused on those of African American and White heritages. The dominance of research on this one segment of the biracial population has in turn led to the myth of a universal biracial experience. There is a critical need to hear the voices and experiences of those who are members of two or more communities of color. While many researchers have recommended that more studies be done with biracial participants from two or more communities of color, few studies have been conducted. The purpose of this study was to explore exclusively the lived experiences ...

Evaluating The Impact Of Small-Group Discussion On Learning In Anorganizational Psychology Class Utilizing A Classroom Response System, Thorhallur Orn Flosason

Dissertations

A classroom response system is a technology that allows individual students to clickers favorably. The second study showed that clicker use during lecture was associated with higher exam scores, but that relationship can be interpreted in several different ways, some of which are not tied to active responding. The implications of these findings with respect to previous research are discussed. provide answers to questions posed by the instructor during lecture using hand held remotes (clickers) that transmit a signal to the instructor's computer via a receiver and computer software (Judson & Sawada, 2002). This instructional technology is widely used in ...


Testing The Effectiveness Of An Interactive Multimedia System To Train Clinicians In Behavioral Activation, Suzanne E. Decker Jan 2011

Testing The Effectiveness Of An Interactive Multimedia System To Train Clinicians In Behavioral Activation, Suzanne E. Decker

Dissertations

Although many treatments for mental health disorders have been found to be effective in research, community clinicians may not receive training in such empirically supported treatments, and therefore, individuals suffering from disorders may not have access to empirically supported treatment in the community. This study examined the use of an interactive multi-media computerized therapy program, Building a Meaningful Life through Behavioral Activation, as a training tool for mental health clinicians (N=21) using a pre-post study design. Participating clinicians were invited to complete this computer program over the course of several weeks, and to complete knowledge quizzes and written responses ...

Living With Bipolar Disorder: A Qualitative Investigation, Richard P. Freedberg

Dissertations

The specific aims of this study were to gain a broader understanding of the lived experience of adults with bipolar disorder and to explore how people diagnosed with bipolar disorder used cognitively, affectively, and spiritually oriented strategies to cope with life stressors and circumstances. The cognitive domain in this investigation was defined as those activities related to how one knows, thinks, or perceives phenomena in a way distinct from emotion. The affective domain referred to the feelings and emotions associated with phenomena that are distinct from cognitive reasoning or knowledge. The spiritual domain was defined as values, attitudes, and beliefs ...


Comparing First Generation And Non-First Generation African-American Students At Predominately White Institutions, Leatrice Renee Brooks Jan 2011

Comparing First Generation And Non-First Generation African-American Students At Predominately White Institutions, Leatrice Renee Brooks

Dissertations

The comparative experiences of first generation and non-first generation Black students at predominately White institutions were examined to gain information about the predictors and relationships between adjustment (including academic and personal-emotional) coping (4 styles), race-related stress, and racial identity development (6 levels). Results from a simultaneous multiple regression revealed a significant positive adjustment profile that included being non-first generation, low disengagement coping, problem-oriented coping, and low pre-encounter self-hatred racial identity development. The standardized coefficients for the first canonical analyses indicated significant relationships between pre-encounter self-hatred and low personal-emotional adjustment; and for the second, low disengagement coping and personal-emotional adjustment. For ...


Jamaican American Child Disciplinary Practices, Stephaney Carter Jan 2011

Jamaican American Child Disciplinary Practices, Stephaney Carter

Dissertations

Little is known about child disciplinary practices in Jamaican American families. Literature on child discipline in Jamaica and other Caribbean nations has mainly focused on physical discipline, and no empirical studies have investigated the types of discipline used in the Jamaican American community. The purpose of this study was to describe current child disciplinary practices in Jamaican American families. A total of 311 primarily first-generation Jamaican American parents from New York City completed the 54-item Jamaican Child Discipline Survey, designed for this study, either online or in paper-pencil format. The main foci of the study included the use of child ...


Using Environmental Sounds To Initiate Receptive Language Training For Children With Autism, Woan Tian Chow Jan 2011

Using Environmental Sounds To Initiate Receptive Language Training For Children With Autism, Woan Tian Chow

Dissertations

A pre-test showed that three pre-school children with autism had difficulty learning to match spoken words to objects (receptive identification). Therefore, they were first taught to match environmental sounds to objects (e.g., to touch a tambourine, when they heard the sound of the tambourine) and then to match spoken words to other objects while continuing to match the mastered environmental sounds to the original objects.

For all three children, simply learning the environmental-sound/object matching did not facilitate learning spoken-word/object matching; however intermixing the training of spoken-word/object matching with the previously mastered environmentalsound/ object matching did result ...


Evaluating The Effects Of Camera Perspective In Video Modelingfor Children With Autism: Point Of View Versus Scene Modeling, Courtney Cotter Jan 2011

Evaluating The Effects Of Camera Perspective In Video Modelingfor Children With Autism: Point Of View Versus Scene Modeling, Courtney Cotter

Dissertations

Video modeling has been used effectively to teach a variety of skills to children with autism. This body of literature is characterized by a variety of procedural variations including the characteristics of the video model (e.g., self vs. other, adult vs. peer). Traditionally, most video models have been filmed using third person perspective (i.e., scene models), where the viewer is watching the actor perform in a scene. Recently, studies have successfully incorporated the use of first person perspective into video models (i.e., point of view models), where the view is directly from the actor's point of ...


Evaluating The Impact Of A Performance Based Methodology On Transfer Of Training, Richard Rashid Kazbour Jan 2011

Evaluating The Impact Of A Performance Based Methodology On Transfer Of Training, Richard Rashid Kazbour

Dissertations

Transfer of training is the degree to which trainees can apply the knowledge, skills, and attitudes gained in training, to the job (Brinkerhoff & Apking, 2001; Wexley & Latham, 1981). Currently only between 5% and 20% of what is learned in training is ever applied on the job (Brinkerhoff, 2006; Broad, 2000; Fitzpatrick, 2001; Mooney & Brinkerhoff, 2008; Tannenbaum & Yulk, 1992). Until recently, most transfer research has focused on what happens in the formal training environment (Brinkerhoff & Montesino, 1995; Holton, Bates, Seyler, & Carvalho, 2003; Noe, 1986; Saks & Belcourt, 2006). At this time, little is known about the effects of work environment factors such as support, feedback, and goal setting, on training transfer.

We utilized a between groups experimental design using surveys, interviews, and behavioral measures to evaluate the impact of performance based work environment factors, on training transfer. Results indicated that participants in the experimental group reported a higher level of ...


The Relationship Between Spirituality And Personality, Kimberly C. Koessel Jan 2011

The Relationship Between Spirituality And Personality, Kimberly C. Koessel

Dissertations

Current literature is lacking a theoretical framework for understanding spirituality within the context of psychological functioning. Despite empirical support for the potential psychological benefits of spirituality, conceptual differences underlying definitions and measurements of spirituality have impeded theory development. Additionally, very few studies have explored spirituality from a secular perspective. The purpose of this dissertation is to examine the relationship between spirituality and personality within a population of undergraduate and graduate students. This research obtains sample data through a demographic questionnaire, a measure of humanistic spirituality, and an inventory of normal personality. Quantitative statistical analyses are employed to explore a variety ...


Understanding The Dimensions Of Spirituality In Caucasian Lesbian, Gay, And Bisexual College Students, Michele L. Mcgrady Jan 2011

Understanding The Dimensions Of Spirituality In Caucasian Lesbian, Gay, And Bisexual College Students, Michele L. Mcgrady

Dissertations

Spiritual development is a critical task for college students, but there is a paucity of information about how college students understand the construct of spirituality. Historically, organized religion has been oppressive to the lesbian, gay, and bisexual (LGB) community. Furthermore, little is known about the spiritual understandings and spiritual experiences of lesbian, gay, and bisexual college students. This quantitative investigation sought to understand the underlying dimensions of spirituality for Caucasian LGB college students through the use of multidimensional scaling. Sixty Caucasian LGB college students were recruited through purposeful and snowball sampling. Findings indicate three dimensions of spirituality for this sample ...


African American Experiences Of Race Relations In The Supervision Dyad, Brandi L. Pritchett-Johnson Jan 2011

African American Experiences Of Race Relations In The Supervision Dyad, Brandi L. Pritchett-Johnson

Dissertations

Everything we do is embedded within multiple contexts of collective and individual historical events that culminate in present day encounters. As an increasing number of racial minorities have entered the ranks as mental health practitioners, the configuration of the treatment and the supervision dyad has changed (Owens-Patterson, 2002). The fundamental aim of this study explored, captured, and described the supervision experience from the nuanced perspective of African American supervisors. A qualitative approach was employed using in-depth interviews to capture the complexity of race relations within the supervision dyad through an African Centered framework, aiding in our understanding of supervised training ...


Dosed Versus Prolonged Exposures: A Direct Comparison Of One-Session Treatments For Animal Phobias, Richard William Seim Jan 2011

Dosed Versus Prolonged Exposures: A Direct Comparison Of One-Session Treatments For Animal Phobias, Richard William Seim

Dissertations

It is widely accepted that for exposure-based therapies to be effective feareliciting stimuli must be presented continuously until there is a marked decrease in the client's anxiety (e.g., Eysenck, 1979; Foa & Kozak, 1986). However, an emerging body of research (cf. Seim, Waller, & Spates, 2010) suggests that a massed series of very brief exposures (< 150 sec) may be effective in the extinction of fear responses. The present study was designed to compare the efficacy and acceptability of two one-session treatments for animal phobias: one that utilized continuous, uninterrupted periods of exposure to a feared animal (Prolonged Exposures) and the other that utilized a massed series of brief (5-120 sec) exposure trials (Dosed Exposures). 24 adults (7 males, 17 females) between the ages of 18 and 57 years (M = 23.6) participated in this study. Each individual met DSM-IV criteria for a diagnosis of snake phobia or spider phobia. Participants were randomly assigned to one of two the two interventions. Both treatments required participants to gradually enter a room, approach, and eventually hold a live ball python or tarantula. Results from mixed model (between x within subjects) analyses of variance showed that the Dosed Exposure treatment performed equally well to Prolonged Exposures at decreasing behavioral avoidance, feelings of anxiety, perceptions of threat, and phobiaspecific cognitions from pre-treatment to post-treatment, and these gains were maintained at one-week follow-up. Although participants receiving Prolonged Exposures reported lower ratings of within-session anxiety, participants in the Dosed Exposure group had lower rates of treatment dropout, better compliance with procedures, and fewer safety-seeking behaviors during the treatment. These findings suggest that, contrary to popular belief, brief exposure trials can be effective in the extinction of phobic responses under certain conditions.

The purpose of the current study was to help understand the lives, worldview, and meaning making of Soviet Holocaust survivors currently residing in the United States. Ethnographic interviews were conducted to explore survivor's childhood, family life, religion, political views, work, and social life. These areas were examined during the following time periods: pre-WWII, during WWII, and post-WWII.

From the collected and analyzed data I was able to offer an insight into the experiences of five Soviet Holocaust survivors under the Soviet regime. I described the struggles that the survivors experienced during the Holocaust, the losses they had suffered, and ...


Social Justice Advocacy And Counselor Education: A Study Of Counselor Educators' And Counseling Interns' Perceptions Of Social Justice Advocacy Training, Darryl C. Steele Jan 2011

Social Justice Advocacy And Counselor Education: A Study Of Counselor Educators' And Counseling Interns' Perceptions Of Social Justice Advocacy Training, Darryl C. Steele

Dissertations

Social justice and advocacy have become increasingly important topics in counselor training. The 2001 Council for the Accreditation of Counseling and Related Educational Programs (CACREP) training standards require counselor education programs to provide studies in social justice and advocacy processes. Moreover, 2009 CACREP standards stipulate that accredited programs must provide advocacy training specific to each specialty area. The American Counseling Association (ACA) adopted advocacy competencies, in part, to guide this training (Goodman, 2009; Lewis, Arnold, House, & Toporek, 2003). Despite training standards and frameworks such as the ACA Advocacy Competencies to help prepare students for advocacy, few studies have explored the ...


Counselor Trainees' Experience Of Analyzing Their Counseling Sessions During A Master's-Level Practicum, Abbie Vanderwege Jan 2011

Counselor Trainees' Experience Of Analyzing Their Counseling Sessions During A Master's-Level Practicum, Abbie Vanderwege

Dissertations

One of the central goals of counselor training is to promote and ensure competence in novice counselors (Krasner, Howard, & Brown, 1998), and effective performance of counseling skills is a key source of competence for counselor trainees (Falender & Shafrankse, 2007). Previous research has separately addressed the advantages of skills-based training (e.g., Buser, 2008; Crews et al., 2005; Urbani et al, 2002); factors associated with counseling self-efficacy (e.g., Larson, 1998; Larson & Daniels, 1998); the Integrated Developmental Model (Stoltenberg, McNeill, & Delworth, 1998) of counselor development; and video review in counselor training (e.g., Pelling & Renard, 1999; Scaife, 2001). None of these studies, however, have concurrently explored changes in these factors from the perspective of master's-level counselor trainees in their first practicum as they use digital recording and playback technology to analyze their counseling skills performance and receive feedback about their performance from their ...


Exploring The Experiences Of Living With A Controversial Illness In Patients With Fibromyalgia, Samantha L. Wheeler Jan 2011

Exploring The Experiences Of Living With A Controversial Illness In Patients With Fibromyalgia, Samantha L. Wheeler

Dissertations

Fibromyalgia is an illness of great controversy estimated to affect approximately 4% of the US population. There are no widely accepted etiological causes or clear physiological explanations of fibromyalgia. Only a few research studies have addressed the concept of illness uncertainty in patients with fibromyalgia. There are no current studies that examine how fibromyalgia patients experience, perceive, and understand their illness in terms of having a syndrome with an unknown etiology.

This qualitative study, using phenomenological methods, explored the concept of unknown etiology as one factor in illness uncertainty. Ten participants, diagnosed with fibromyalgia from 2-15 years were interviewed. The ...


Effectiveness Of A Motivational Enhancement Group Treatment In A Community Treatment Program With A Substance Abusing Population, Matthew S. Willerick Jan 2011

Effectiveness Of A Motivational Enhancement Group Treatment In A Community Treatment Program With A Substance Abusing Population, Matthew S. Willerick

Dissertations

Motivational interviewing (MI) is a directive, client-centered intervention to elicit behavior change by assisting clients in the exploration and resolution of ambivalence toward change. MI-inspired approaches have been used in an attempt to facilitate change in a wide variety of domains including alcohol and drug abuse, safe water handling practices, dual diagnoses, gambling, spousal abuse, health related areas, mood and anxiety disorders, and parental engagement. MI seeks to resolve ambivalence in the direction of change by increasing the client's self-efficacy. This is accomplished by combining clientcentered (e.g., reflective listening) and directive strategies (e.g., attending selectively to change ...

Short-Term Nicotine Abstinence And Decision Making, Gabriel D. Searcy Jan 2011

Short-Term Nicotine Abstinence And Decision Making, Gabriel D. Searcy

Dissertations

Research has shown that acute drug administration may affect impulsivity (i.e., choice for small, immediate rewards over large, delayed rewards) on laboratory delay-discounting tasks. Few studies have investigated how drug abstinence affects impulsivity. Investigating how drug abstinence affects impulsivity may be relevant to preventing relapse. Two previous studies have investigated the effects of short-term nicotine abstinence on impulsivity using delay-discounting tasks. The results were mixed, one study suggested that choices became more impulsive (i.e., delayed money was devalued) under nicotine deprivation. One goal of the present research was to further investigate how nicotine deprivation affects delay-discounting for money ...


Examination Of Anxiety And Substance Use Symptoms In Trauma Exposed Versus Environmentally Stressed College Students, Theresa M. Souza Jan 2011

Examination Of Anxiety And Substance Use Symptoms In Trauma Exposed Versus Environmentally Stressed College Students, Theresa M. Souza

Dissertations

Anxiety is a common problem among the college population, which rarely occurs in isolation. Oftentimes, an individual abuses substances in an attempt to eliminate the short term affect of these conditions. Post Traumatic Stress Disorder (PTSD), is the most persistent and severe type of anxiety disorder. It has been a long-standing belief within the psychological community that in order for PTSD to develop, the individual must first experience a traumatic event which meets certain criteria and must evidence a definable emotional response during the event. A recent study found PTSD in individuals who had not experienced the type of trauma ...


Assessing The Effects Of A Rectangular Rapid-Flashing Beacon On Vehicle Speeds Along A Four-Lane Divided Highway, Michelle Van Wagner Jan 2011

Assessing The Effects Of A Rectangular Rapid-Flashing Beacon On Vehicle Speeds Along A Four-Lane Divided Highway, Michelle Van Wagner

Dissertations

In 2008, nearly 31% of vehicle fatalities were related to failure to adhere to safe vehicle speeds (National Highway Traffic Safety Administration (NHTSA), 2009). Two studies were conducted to evaluate the effects of a Rectangular Rapid-Flashing Beacon (RRFB) triggered by excessive speed on vehicle speed using a combined alternating treatments and reversal design. Experiment 1 assessed the RRFB's impact on speeds as compared to baseline conditions only. Experiment 2 compared the RRFB to two standard beacon configurations. Both experiments were conducted at the same site during approximately the same time period and both employed the same data collection methodology ...

The Impact Of Structured Group Counseling On Resiliency, Self-Efficacy, And Racialidentity Among African American Female Teenagers, Lashonda B. Fuller

Dissertations

African American female teenagers are at-risk for low academic achievement as well as personal and social problems. These concerns have the potential to impact their psychological development including resiliency, self-efficacy, and racial identity. This is an issue that needs focused attention. Therefore, the purpose of this dissertation was to determine if a structured group counseling model effectively impacts African American female teenagers‟ resiliency, self-efficacy, and racial identity. The researcher conducted four structured counseling groups over a period of 20 weeks; however, the teenagers participated in consecutive 10 week sessions. The treatment was applied to two groups simultaneously, and the groups ...


Sense Of Coherence: The Relationship To Personal Growth And Distressafter A Breakup, Kristin R. Gillen Jan 2011

Sense Of Coherence: The Relationship To Personal Growth And Distressafter A Breakup, Kristin R. Gillen

Dissertations

Romantic relationship issues are among the most common presenting concerns in university counseling center settings (Benton, Robertson, Tseng, Newton, & Benton, 2003; McCarthy, Lambert, & Brack, 1997). Specifically, romantic relationship breakups have received attention in the literature, as these particular losses tend to generate a myriad of emotions for college students. While numerous studies have explored distress reported after a breakup, few studies have focused on the personal growth individuals could potentially gain after experiencing a breakup (Tashiro & Frazier, 2003). The current study explores both the distress as well as personal growth individuals endorsed subsequent to a breakup.

Since relationship breakups appear to be ...


Evaluating The Effects Of A Job-Aid For Teaching Visual Inspection Skills To University Students, Candice M. Jostad Jan 2011

Evaluating The Effects Of A Job-Aid For Teaching Visual Inspection Skills To University Students, Candice M. Jostad

Dissertations

Visual inspection is the primary method of data analysis used in behavior analysis. Thus, it is important that behavior analysts have the skills necessary for accurate visual inspection. Research has shown that visual inspection can sometimes be unreliable, which has broad implications for the evaluation of treatment effects using this method. Traditional lectures have been shown to be ineffective in teaching visual inspection skills to a satisfactory level, although improvements in visual inspection have been accomplished using statistical methods and aids such as celeration lines superimposed on graphs. However, these methods are not effective when the aids are removed and ...


Psychometric Properties Of Diagnostic Assessment Instrumentsfor Autism Spectrum Disorders In A Community Sample Aged 2 Through 17 Years, Sheryl Lozowski-Sullivan Jan 2011

Psychometric Properties Of Diagnostic Assessment Instrumentsfor Autism Spectrum Disorders In A Community Sample Aged 2 Through 17 Years, Sheryl Lozowski-Sullivan

Dissertations

Recent estimates of the incidence and prevalence of autism spectrum disorders (ASDs) indicate substantial increases over the past 20 years (Centers for Disease Control and Prevention, 2009; Fombonne, 2009; Matson & Kozlowski, 2011; Schreibman & Koegel, 2005; Wing & Porter, 2002), in part because of the availability of significantly improved diagnostic assessment instruments (Lord & Corsello, 2005; Schreibman, 2005). In highly structured research settings, some of these diagnostic instruments correlate well with each other; however, few studies have examined the relation between these diagnostic tools in traditional clinical practice (Mazefsky & Oswald, 2006; South et al, 2002). This study examined archival client data for 77 cases from two outpatient clinics serving children with suspected ASD to investigate the psychometric properties of diagnostic assessments when used in clinical practice ...


The Effects Of Yellow Rectangular Rapid-Flashing Beacons (Rrfbs) Onmotorists' Yielding, Exit Lane Encroachment And Conflicts At Fire Station Exits, Erick K. Marmolejo Jan 2011

The Effects Of Yellow Rectangular Rapid-Flashing Beacons (Rrfbs) Onmotorists' Yielding, Exit Lane Encroachment And Conflicts At Fire Station Exits, Erick K. Marmolejo

Dissertations

The purpose of the current study was to explore the extent to which yellow rectangular rapid-flashing beacons (RRFBs) affected motorists' yielding, exit-lane encroachment and conflicts at fire station exits. This study explored the use of RRFBs attached to sign prompts that alerted motorists to the presence of exiting emergency vehicles. These signs were activated only during an exit event. It was hypothesized that motorists would increase their frequency of safe and legal yielding in the presence of the RRFB intervention when compared to the absence of contextually activated RRFB units. This study was conducted in a midwestern town in front ...
