Self-efficacy, a known predictor of a wide range of health behaviors, has not been investigated in studies of adherence to antihypertensive medications. A medication adherence self-efficacy scale was developed and evaluated in ambulatory hypertensive African-American patients in two sequential phases. For the item-generation phase, open-ended interviews with 106 patients were used to elicit their experiences with taking antihypertensive medications. Using qualitative techniques, responses were recorded verbatim, coded, and sorted into nine categories of barriers and facilitators of medication adherence. Concepts from categories were formatted into an initial 43-item self-efficacy questionnaire, which was administered to another group of 72 patients for the item analyses phase. Twenty-six items were retained for the final self-efficacy scale based on item-to-total correlation coefficient >0.5, kappa >0.4, and clinical relevance of individual items. Clinicians and researchers can use this scale to identify situations in which patients have low self-efficacy in adhering to prescribed medications.
自我效能感是多种健康行为的已知预测指标，但尚未在抗高血压药物依从性研究中进行调查。我们开发了一种药物依从性自我效能量表，并在两个连续阶段对非卧床高血压非裔美国患者进行了评估。在项目生成阶段，对106名患者进行了开放式访谈，以了解他们服用抗高血压药物的经历。使用定性技术，逐字记录回答，编码并分为药物依从性的九类障碍和促进因素。将类别中的概念整理成一份初始的43项自我效能量表，用于项目分析阶段，该量表被施用于另一组72名患者。基于项目与总分相关系数>0.5、kappa>0.4以及单个项目的临床相关性，最终的自我效能量表保留了26个项目。临床医生和研究人员可以使用该量表来识别患者在坚持服用处方药方面自我效能感较低的情况。
