Ethical Dilemmas In Managed Mental Health Care, Kolina J. Delgado
Ethical Dilemmas In Managed Mental Health Care, Kolina J. Delgado
Psychology Student Publications
In the United States, health care has become a significant political, social, economical, and ethical concern. It is difficult to identify a professional or personal area of life that is not impacted in some way by health care. According to the United States Census Bureau (2010) approximately 255 million Americans were enrolled in some form of managed health care in 2009. The current paper describes the evolution of managed care, common practices in managed care, and ethical issues inherent to working in a managed mental health care system.
Dual Diagnosis: Impact, Assessment, And Treatment In Co-Occurring Substance Abuse And Severe Mental Illness, Kolina J. Delgado
Dual Diagnosis: Impact, Assessment, And Treatment In Co-Occurring Substance Abuse And Severe Mental Illness, Kolina J. Delgado
Psychology Student Publications
Mental illness and substance use disorders individually comprise a challenging area of work for health care professionals. In combination, these issues create an even greater demand; a demand that many health care professionals find themselves ill prepared to address (McKeown, 2010). The prevalence rates of substance disorders and psychiatric disorders co-occurring in one person, a condition referred to as dual diagnosis, are astoundingly high.
The Statistical Properties Of The Survivor Interaction Contrast, Joseph W. Houpt, James T. Townsend
The Statistical Properties Of The Survivor Interaction Contrast, Joseph W. Houpt, James T. Townsend
Joseph W. Houpt
The Survivor Interaction Contrast (SIC) is a powerful tool for assessing the architecture and stopping rule of a model of mental processes. Despite its demonstrated utility, the methodology has lacked a method for statistical testing until now. In this paper we briefly describe the SIC then develop some basic statistical properties of the measure. These developments lead to a statistical test for rejecting certain classes of models based on the SIC. We verify these tests using simulated data, then demonstrate their use on data from a simple cognitive task.

Functional Principal Components Analysis And The Capacity Coefficient, D. Burns, Joseph W. Houpt, M. J. Endres, J. T. Townsend
Functional Principal Components Analysis And The Capacity Coefficient, D. Burns, Joseph W. Houpt, M. J. Endres, J. T. Townsend
Joseph W. Houpt
The capacity coefficient is a well established measure of the efficiency of processing combined sources of information. It has been applied to measure cognitive processes ranging from audio-visual integration to face perception. Recently, the capacity coefficient has also been applied in various clinical situations. Typical clinical analysis, such as structural equation modeling, use scalar values or vectors with limited length as input. We explored the use of functional principal component analysis (fPCA) to allow researchers to describe the capacity coefficient, a continuous function of time, with a small set of discrete values. The fPCA approach was compared with two simple …
A New Perspective On Visual Word Processing Efficiency, Joseph W. Houpt, James T. Townsend
A New Perspective On Visual Word Processing Efficiency, Joseph W. Houpt, James T. Townsend
Joseph W. Houpt
As a fundamental part of our daily lives, visual word processing has received much attention in the psychological literature. Despite the well established perceptual advantages of word and pseudoword context using accuracy, a comparable effect using response times has been elusive. Some researchers continue to question whether the advantage due to word context is perceptual. We use the capacity coefficient, a well established, response time based measure of efficiency to provide evidence of word processing as a particularly efficient perceptual process to complement those results from the accuracy domain.

Measuring Conscientiousness with Explicit and Implicit Measures Although the literature has a wealth of research predicting salesperson performance, the literature is unclear. Even meta-analytic research (Barrick et al., 2001; Schmidt & Hunter, 1998; Vinchur et al. 1998) appears inconsistent. The main goal of this study was to determine if the relationships were of a nonlinear nature and leading to confusion. This study found that the relationships between sales performance depended on the type of criteria (supervisor ratings or performance versus sales revenue or effectiveness) and the type of relationship examined (linear or nonlinear). This study was successful in demonstrating a …
The Effects Of Mood And Dispositional Affectivity On Self-Reported Job Satisfaction, Cristina D. Kirkendall
The Effects Of Mood And Dispositional Affectivity On Self-Reported Job Satisfaction, Cristina D. Kirkendall
Browse all Theses and Dissertations
Job satisfaction has several antecedents, including situational factors (e.g., pay, job characteristics), personality factors (e.g., positive and negative affectivity), and social interactions at work. Job satisfaction is most often measured with self-report surveys which may not effectively capture unconscious attitudes or context effects such as mood. Mood at time of survey completion has been shown to have an effect on self-reported satisfaction measures. This study uses animal-related video clips as a mood induction and examines the effect of induced mood and personality factors on self-report measures of job satisfaction.

The following study examines the relationship between amount of information, performance, expertise, and temporal awareness during a high fidelity military battle command simulation. The current study provides an in situ example of temporal estimation which is lacking in the current body of research. Twenty Ohio National Guardsmen of varying expertise played the role of battle commander during the simulation. Novice behavior differed from experts. Novice indications of temporal awareness did not vary with contextual change. However, they provided non-detailed temporal utterances and a relationship between temporal awareness and performance. This pattern suggests that they were overwhelmed by the amount of …
The Importance Of Perceived Similarity Within Faculty-Faculty Mentoring Dyads, Emily N. Polander
The Importance Of Perceived Similarity Within Faculty-Faculty Mentoring Dyads, Emily N. Polander
Browse all Theses and Dissertations
This study investigated the effects of gender similarity, perceived similarity, and relationship type (formal vs. informal) within faculty-faculty mentoring dyads on various mentoring outcomes from the protégé's perspective. Perceived similarity was expected to be a stronger predictor of relationship satisfaction, affective commitment, job satisfaction, and turnover intent than gender similarity. Perceived similarity was also examined as a potential mediator of relationship type and relationship satisfaction. Tenure-track faculty who reported having mentors (N = 45) answered questions regarding their primary career mentor and other workplace attitudes. Results indicated that perceived similarity had a positive, greater effect than gender similarity on relationship …

The fakability of three measures of conscientiousness was examined: the International personality Item Pool (IPIP), the Conditional Reasoning Test, and Implicit Association Tests (IAT). Data from a student sample (N = 442) found the Conditional Reasoning and IATs were the least susceptible to faking, but they did not have a meaningful relationship with the IPIP. The Conditional Reasoning Test was the best non-cognitive predictor of College GPA (r = .23, p < .01), perhaps due to the fact it may tap cognitive ability as evidenced by its significant correlation with the ACT (r = .41, p < .01). The explicit (self- report) and implicit (IAT) measures of conscientiousness had a low positive correlation with one another. Some researchers may use this finding as evidence that they are measuring different aspects of the construct.
Team Coordination As A Mediator Of Stress Appraisals And Team Performance, Gaea Megan Payton
Team Coordination As A Mediator Of Stress Appraisals And Team Performance, Gaea Megan Payton
Browse all Theses and Dissertations
Threat stress appraisals can negatively affect individuals by decreasing performance (Gildea, Schneider, & Shebilske, 2007). Performance is also influenced by a team's ability to coordinate tasks (Entin & Serfaty, 1999). This study investigated the link between team stressor appraisals, coordination, and performance. Using a simulated team environment, teams were evaluated on their perceived stress appraisals, coordination as indicated through instant messaging, and team performance. Findings showed that team stressor appraisals were marginally related to coordination and significantly related to performance. Coordination was related to team performance. Further research should be performed using varied levels of a stressful scenario to evaluate …
Do Applicants And Incumbents Respond To Personality Items Similarly? A Comparison Using An Ideal Point Response Model, Erin L. O'Brien
Do Applicants And Incumbents Respond To Personality Items Similarly? A Comparison Using An Ideal Point Response Model, Erin L. O'Brien
Browse all Theses and Dissertations
This study examined the extent to which applicants and incumbents use different response processes when responding to personality items. It was hypothesized that applicants' responses to personality items will be more similar to a dominance response model and that incumbents' responses will be more similar to an ideal point response model. I used item response theory to estimate sample data from applicants (N = 1509) and incumbents (N = 1568) who completed the Sixteen Personality Questionnaire Select. Differential item (DIF) and test functioning (DTF) analyses were conducted using the generalized graded unfolding model (GGUM), which is based on ideal point …
Influence Of Edge Rate, Global Optical Flow Rate, Angle, And Expansion Rate On Braking Behavior, Sheldon M. Russell
Influence Of Edge Rate, Global Optical Flow Rate, Angle, And Expansion Rate On Braking Behavior, Sheldon M. Russell
Browse all Theses and Dissertations
A driving simulator was used to understand the way humans control collisions. Based on the research of Smith et al. (2001), and McKenna (2004), this study altered distance to and size of a target to determine if optical angle and expansion rate were used independently to control behavior in a collision event rather than combined into a single variable, tau, as suggested by Lee (1976). Furthermore, edge rate as defined by Denton (1980) and global optical flow rate (GOFR) (Warren, 1982) were considered as possible visual sources of egomotion information. Similar to the results found by McKenna (2004), participants appeared …

An Examination Of Type I Errors And Power For Two Differential Item Functioning Indices, Patrick Carl Clark Jr.
Browse all Theses and Dissertations
This study examined two methods for detecting differential item functioning (DIF): Raju, van der Linden, and Fleer's (1995) differential functioning of items and tests procedure (DFIT) and Thissen, Steinberg, and Wainer's (1988) likelihood ratio test (LRT). The major research questions concerned which test provides the best balance of Type I errors and power and if the tests differ in terms of detecting different types of DIF. Monte Carlo simulations were conducted to address these questions. Equal and unequal sample size conditions were fully crossed with test lengths of 10 and 20 items. In addition, α and β parameters were manipulated …
