Stress, Anxiety, And Somatic Symptoms: A Comparison Of Biomarkers In A Clinical Sample, David J. Finitsis Mar 2013

Stress, Anxiety, And Somatic Symptoms: A Comparison Of Biomarkers In A Clinical Sample, David J. Finitsis

Master's Theses

Anxiety disorders are the most prevalent class of mental disorders, often characterized by a chronic course and comorbid psychopathology. The anxiety-stress literature utilizing cortisol as a biomarker of the hypothalamus pituitary adrenal (HPA) axis has been inconsistent. The establishment of salivary alpha-amylase (sAA) as a biomarker of sympathetic nervous system (SNS) activation allows researchers an opportunity to examine the stress response more fully. This study sought to explore relationships between trait anxiety and salivary stress biomarkers in an outpatient sample attending a specialized anxiety treatment center. Multiple regression and moderator analyses were conducted to examine associations between psychosocial and physiological …


Measurement Invariance Of Assessment Center Ratings: Consistency Of Dimensional Constructs Across Exercises, Jin Lee Jan 2013

Measurement Invariance Of Assessment Center Ratings: Consistency Of Dimensional Constructs Across Exercises, Jin Lee

Master's Theses

The criterion-related validity of assessment centers (ACs) has been consistently supported. However, there has been an ongoing debate about AC construct validity in regard to low dimension variance and overriding exercise variance. Many studies that showed weak dimension effects in ACs have been based on the multitrait-multimethod (MTMM) framework which posits cross-situational variance as error and all capability dimensions can be equally represented from different exercises. The goal of this study is to introduce a measurement invariance (MI) framework for evaluating the construct validity of AC dimensions. Specifically, MI analysis was used to test whether the construct meaning of AC …
