Validation Of A Serotonin Depletion Checklist In Parkinson’S Disease, Kelly Diane Darby Holder
Validation Of A Serotonin Depletion Checklist In Parkinson’S Disease, Kelly Diane Darby Holder
Loma Linda University Electronic Theses, Dissertations & Projects
The distinctive pathological marker of Parkinson’s Disease (PD) is the progressive death of neurons that produce dopamine; however, there are also major alterations in the production of quantities of other neurotransmitters, such as norepinephrine and serotonin that contribute to the signs, symptoms, neuropsychological manifestations of the diseases. PD patients can be divided into classes based on the manifestation of motor symptoms, type A, classified as tremor dominant, and type B PD, classified as akinetic. Type B PD patients, often manifest symptoms in which serotonin deficiency plays an important role, such as frontal cognitive impairments, which often includes a history of …
The Effects Of Parcels And Latent Variable Scores On The Detection Of Interactions In Structural Equation Modeling, Thomas D. Fletcher
The Effects Of Parcels And Latent Variable Scores On The Detection Of Interactions In Structural Equation Modeling, Thomas D. Fletcher
Psychology Theses & Dissertations
Numerous theories in the behavioral and organizational sciences involve the regression of an outcome variable on component terms and their product to evaluate interaction effects. There are numerous statistical difficulties with this multiple regression approach. The most serious is measurement error, requiring the use of structural equation modeling. Jöreskog and Yang (1996) described a nonlinear structural equation modeling procedure that incorporates mean structures in the covariance analysis. They demonstrated that only one indicator for the product term is necessary for model identification. Unfortunately, the Jöreskog-Yang procedure leads to biased estimates of the product coefficient. In this dissertation, I propose that …
Motivated Breast Cancer Screening Behavior And Its Cultural Antecedents, Patricia M. Flynn
Motivated Breast Cancer Screening Behavior And Its Cultural Antecedents, Patricia M. Flynn
Loma Linda University Electronic Theses, Dissertations & Projects
Discrepancies in breast cancer screening behavior exist among various ethnic groups in the United States (Jacobs & Lauderdale, 2001), with Latino American women reporting particularly low screening rates in comparison to Anglo American women (ACS, 2002). Research indicates that behavior is in part influenced by aspects of culture and relevant psychological processes (Betancourt & Lopez, 1993; Betancourt & Fuentes, 2001). This study was designed to investigate the relations among cultural values, attributions regarding the causes for not screening, related emotions, expectancy that screening leads to early detection and value incentive of early detection as determinants of breast cancer screening intention …
Literature Review: Diagnostic Utility Of The Million Clinical Multiaxial Inventories In Various Settings : The Detection And Effect Of Faking Good ; Research Project : The Impact Of Faking-Good On The Mcmi-Iii : Implications For Child Custody Evaluations, Paul Lenny
Theses : Honours
Research surrounding the ability of the Millon Clinical Multiaxial Inventory (MCMI; Millon, 1977, 198 7, 1994) to detect faking good was reviewed; along with the effect faking has on diagnostic accuracy. Limited research indicates moderate success of the MCMI validity indices (VI) at detecting faking good. Suggested improvements include developing a fake-good profile combining the personality scales and VI and developing new base rate adjustments with populations likely to fake good. Faking good reduces the overall diagnostic accuracy of the test but determining local base rates of faking to produce optimal cut-offs for the VI would improve diagnostic utility. Future …
