自我效能感是一种已知的健康行为预测因子，但在抗高血压药物依从性研究中尚未进行研究。药物依从性自我效能量表的开发和评估动态高血压非洲裔美国患者在两个连续的阶段。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，反应逐字记录，编码，并分为9类的障碍和药物依从性的促进因素。从类别的概念被格式化成一个初始的43项自我效能问卷，这是管理到另一组的72例患者的项目分析阶段。根据项目与总体的相关系数> 0.5，Kappa > 0.4，以及单个项目的临床相关性，保留26个项目用于最终的自我效能量表。临床医生和研究人员可以使用这个量表来识别患者在坚持处方药物方面自我效能低下的情况。(C)2003年爱思唯尔公司All rights reserved.
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. (C) 2003 Elsevier Inc. All rights reserved.
