自我效能感是健康行为的一个重要决定因素，可以有针对性地进行干预。很少有人努力发展有效的措施，自我效能与服药依从性研究。本研究的目的是确定长期用药行为自我效能量表（LTMBSES）的效标效度。汇总了6项现有移植、高脂血症和AIDS/HIV患者依从性研究（n = 1021）的个体患者数据。通过评估LTMBSES评分和药物依从性之间的关系来确定有效性-自我报告和电子监测。发现LTMBSES评分与依从性之间的关系较弱，这可能归因于天花板效应，由过于同质的人群和/或未能挑战患者的量表引起。广义估计方程显示，总平均自我效能得分预测报告的药物依从性（p < .0001）。受试者操作特征曲线显示曲线下面积为0.67，表明具有显著性（p <0.0001），但预测能力较差。长期用药行为自我效能量表的标准效度证据尚不令人信服。未来的研究应该集中在：（1）在依从性水平更异质的人群中进行验证，（2）通过提及“总是无一例外地服用药物”使量表更具挑战性。"
Self-efficacy is an important determinant of health behavior that can be targeted for intervention. Little effort has been given to the development of valid measures for self-efficacy with medication taking for adherence research. The purpose of this study was to determine the criterion validity of the Long-Term Medication Behavior Self-Efficacy Scale (LTMBSES). Individual patient data from 6 existing adherence studies in transplant, hyperlipidemia, and AIDS/HIV patients (n = 1021) were pooled. Validity was determined by assessing the relation between the LTMBSES score and medication adherence--both self-reported and electronically monitored. A weak relationship was found between the LTMBSES score and adherence, which can possibly be attributed to a ceiling effect, caused by a too homogeneous population and/or a failure of the scale to challenge patients. Generalized Estimating Equations revealed that the total average self-efficacy score predicted reported medication adherence (p < .0001). The Receiver Operating Characteristic curve revealed the area under the curve was 0.67, indicating a significant (p < .0001), but poor predictive capability. Evidence for criterion validity of the Long-Term Medication Behavior Self-Efficacy Scale is not yet convincing. Future research should focus on: (1) validation in a population with a more heterogenous level of adherence, and (2) making the scale more challenging by referring to "always taking the medication without exception."
