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.
