Internal consistency reliability coefficients ranged from 0.83 to 0.93. Item-total correlations ranged from 0.20 to 0.63 for Behavior, 0.46 to 0.70 for Motivation, and 0.40 to 0.74 for Self-efficacy, meeting the cutoff set a priori at 0.15. The sample included 213 English-speaking inner-city residents with HBP (mean age, 68.6 years 76.1% women 81.7% African American). Guided by 2 validated theoretical approaches-Orem's self-care model and Motivational Interviewing-the HBP SCP includes 3 scales that can be used together or independently: Behavior, Motivation, and Self-efficacy. The HBP SCP encompasses comprehensive domains of HBP self-care behaviors. The purpose of this study was to develop and validate a new tool-the HBP Self-Care Profile (HBP SCP)-in a sample of inner-city residents. A number of hypertension (HBP) self-care instruments are available, but existing tools do not capture all the critical domains of HBP self-care and have limited evidence of reliability and validity. Adequate self-care is crucial for blood pressure control.
