BACKGROUND:
Despite evidence that adequate and sustained blood pressure (BP) reduces morbidity and mortality, lack of adherence to recommended treatment regimens is a major cause of uncontrolled BP among African/Black American (AA) women. The national initiative to increase BP control among AAs by 50% makes clear the need for culturally appropriate instruments to assess factors related to adherence to recommended treatment. But there is a paucity of measures sensitive to the needs of hypertensive AA women.
OBJECTIVE:
The objective of the study was to develop a culturally sensitive instrument (Adherence to Hypertension Treatment Factors Questionnaire) to measure factors that influence adherence to high BP treatment regimens in AA women.
METHODS:
Focus group interviews with 20 AA women were used to construct an 18-item questionnaire. The questionnaire was based on the Hill-Levine model of predisposing, enabling and reinforcing factors. To evaluate content validity, three experts (two adherence to treatment researchers and a cardiovascular health researcher) and five randomly selected AA women from the participant pool reviewed the questionnaire. A total of 147 hypertensive AA women who met the inclusion criteria (AA woman receiving treatment for HBP, 35 years or older, able to read 6th grade level English, and not having a condition that prevents her from completing a survey), were asked to complete a survey that tapped adherence and factors related to adherence as well as demographic information. The study participants were recruited from a free inner city clinic in West Los Angeles, California. The participation rate was 48% (70/147). Distributions and summary statistics (e.g., mean, SD) were examined for items and scales. Internal consistency reliability for multi-item scales was estimated using Cronbach's coefficient alpha. The associations of predisposing, enabling and reinforcing factors with adherence were estimated using linear regression. Pearson product moment correlations were computed between the new18-item adherence measure and the Hill-Bone High Blood Pressure Compliance Scale, Enhancing Recovery from Coronary Heart Disease (ENRICHD) Social Support Inventory (ESSI), Alcohol Screening instrument (CAGE), and Check Your High Blood Pressure prevention IQ Quiz.
RESULTS: Internal consistency reliability for the 18-item measure of adherence factors related to treatment recommendations was 0.79 (standardized). The measure was significantly correlated with: Hill-Bone scale, 0.40 (p = 0.0017), ESSI, 0.32 (p = 0.0112), and CAGE, - 0.29 (p = 0.0273). The ESSI, 0.15 (p = 0.0098) and CAGE, - 0.43 (p = 0.0305) were significantly associated with the new adherence measure even after adjusting for BP stage. These reported betas were not standardized. Standardized values for the ESSI was 3 (p = 0.0098) and - 2.26 (p = 0.0305) for the CAGE.
IMPLICATIONS: Social support has a positive association and alcohol abuse a negative association with adherence, even controlling for HBP diagnostic stage The new measure of HBP adherence factors contributes to closing the gap on paucity of culturally sensitive measures for hypertensive AA women.
