Abstract
The purpose of the present research was to interrelate dimensions of anxiety in a psychiatric population, based primarily on the conceptual formulation of Templer, Corgiat, and Brooner (1984). Two hundred twenty outpatients served as subjects. The Fear Survey Schedule, State-Trait Anxiety Inventory, Hamilton Anxiety Scale, and a Likert-formated criterial symptom checklist for Generalized Anxiety Disorder (GAD) were employed to derive measures of Severity, Stimulus Specificity, Subjective Component (Cognitive vs. Somatic), Chronicity, and Temporal Constancy (Sometimes vs. Always present). Principal components factor analysis yielded three distinct dimensions of anxiety: Morbidity, Subjective Component, and Chronicity. Clinical and theoretical relevance of these findings are discussed specific to construction of a working model of anxiety, clinical assessment of anxiety response systems, and the feasibility of a dimensional approach to understanding psychopathology.
