To compare beliefs about medicines, as measured by the BMQ-General questionnaire, at two time points for the same respondents.
Respondents completed the BMQ-General as part of two separate postal questionnaires, administered with an intervening period of almost 4 years. BMQ-General scores were compared for all respondents at the two time points (2002 and 2005). Scores were also compared for three mutually exclusive groups based on changes in self-reported health status (better, worse or no change) during the intervening period.
BMQ-General scores remained stable over time: no statistically significant differences were observed in individuals' scores after almost 4 years. This finding persisted amongst respondents who reported changes in health status during the intervening period.
General beliefs about medicines appear to remain stable over time, irrespective of changes in health status. Further research should be done to establish whether specific beliefs about medicines prescribed for individuals are similarly stable.
Adherence is known to be associated with beliefs about medicines. The observed stability in such beliefs could have implications for the design of interventions to improve adherence to prescribed medication regimes.
通过比较同一批调查对象在两个时间点的通用药物信念量表（BMQ-General questionnaire）的测量结果，来比较他们的药物信念。
调查对象在两次独立的邮寄问卷中完成了通用药物信念量表（BMQ-General）的填写，两次调查的间隔时间近 4 年。比较了两个时间点（2002 年和 2005 年）所有调查对象的 BMQ-General 得分。同时还根据两次调查期间自我报告的健康状况变化（更好、更差或无变化），将调查对象分为三个互斥的组进行了评分比较。
BMQ-General 评分在时间上保持稳定：近 4 年后，个体评分没有统计学上的显著差异。这一发现也存在于在两次调查期间报告健康状况发生变化的调查对象中。
一般的药物信念似乎随着时间的推移而保持稳定，无论健康状况是否发生变化。应进一步研究以确定针对个体开具的特定药物的信念是否同样稳定。
已知依从性与药物信念有关。观察到的这种信念的稳定性可能对改善处方药物治疗方案依从性的干预措施的设计具有重要意义。
