To examine the association between medication expectations and subsequent experience on treatment satisfaction and intention to continue using the medication.
A longitudinal study with two surveys administered to each patient. Patients prescribed a new medication were recruited in pharmacies within Michigan. Medication-related expectations were evaluated at baseline. Experiences, satisfaction and intent to continue were evaluated a month later. Analyses used included factorial ANOVA models, multiple linear regressions and structural equation modeling (SEM). Impact of satisfaction on intention to continue was evaluated using correlation analysis and SEM.
A total of 344 usable responses were obtained. SEM showed that expectation scores were not associated with both experience (path coefficient = 0.10) and satisfaction (path coefficient = 0.02, NS). On the other hand, experience was strongly associated with satisfaction (path coefficient = 0.89) and satisfaction was strongly associated with intent to continue using the new medication (path coefficient = 0.81).
This study empirically supports the value of the patient's experience and its contribution to satisfaction, which in turn is associated with intended continued use mainly due to greater effectiveness of the newly prescribed medication. Satisfied consumers should be more adherent, thus enhancing the probability of positive therapeutic outcomes.
探讨用药期望与后续治疗满意度体验以及继续用药意愿之间的关联。
对每位患者进行两次调查的纵向研究。在密歇根州的药店招募新开药物处方的患者。在基线时评估与药物相关的期望。一个月后评估体验、满意度和继续用药意愿。所采用的分析方法包括析因方差分析模型、多元线性回归和结构方程模型（SEM）。使用相关分析和SEM评估满意度对继续用药意愿的影响。
共获得344份有效回复。SEM显示，期望得分与体验（路径系数 = 0.10）和满意度（路径系数 = 0.02，无显著性差异）均无关联。另一方面，体验与满意度密切相关（路径系数 = 0.89），且满意度与继续使用新药的意愿密切相关（路径系数 = 0.81）。
本研究通过实证支持了患者体验的价值及其对满意度的贡献，而满意度又主要因新处方药物疗效更佳与预期的持续用药相关。满意的消费者应该更依从，从而提高积极治疗结果的可能性。
