Leventhal and Diefenbach's (1991) self-regulatory theory is discussed in explaining the dynamic nature of “how” and “what” people think about hypertension and how this information is different according to severity of hypertension. Using a sample of hypertensive adults who had controlled and uncontrolled blood pressure (BP) status, the factor structure of the Cognitive Representations of Hypertension (CRHTN) scales, an instrument based on self-regulatory theory of Leventhal & Diefenbach, is examined through exploratory, confirmatory, and multigroup factor analyses. Results indicate that a 5-factor model is representative of theoretical constructs of disease label or symptoms, consequences, and controllability. The model accurately fits observed data for outpatients with controlled and uncontrolled BP status. Results provide support for an understanding of individuals’ cognitive structuring of disease-specific attitudes, beliefs, and self-management skills.
