The Structure of Perceived Emotional Control: Psychometric Properties of a Revised Anxiety Control Questionnaire

The psychometric properties of the Anxiety Control Questionnaire (ACQ) were evaluated in 1,550 outpatients with DSM-IV anxiety and mood disorders and 360 nonclinical participants. Counter to prior findings, exploratory factor analyses produced a 3-factor solution (Emotion Control, Threat Control, Stress Control) based on 15 of the ACQ's original 30 items. Factor analyses in two independent clinical samples (e.g., confirmatory factor analysis, CFA) replicated the 3-factor solution. Multiple-groups CFAs indicated that the measurement properties of the ACQ were invariant in male and female patients, and that the ACQ was largely form and parameter equivalent in a clinical versus nonclinical sample. Hierarchical analysis supported the existence of a higher-order dimension of perceived control. Structural regression analyses indicated that each of the ACQ factors accounted for significant unique variance in one or both latent factors representing the dimensions of autonomic anxiety and depression. The results are discussed in regard to their conceptual and psychometric implications to the construct of perceived emotional control..
