TITLE Validation of the Swedish version of the Beliefs about Medicines Questionnaire, based on people with epilepsy. PURPOSE The aims of the study were to explore the latent structure of the Swedish Beliefs about Medicines Questionnaire (BMQ), to investigate its reliability and to identify the extent to which individual factors among people with epilepsy (PWE), as well as their general beliefs about medication, predict their beliefs about their specific anti-seizure drugs (ASDs). METHODS One-hundred and fifty six included study participants diagnosed with epilepsy and with a well-established neurological follow-up completed an array of rating scales. Included were the Swedish BMQ, which captures beliefs about medicines, scales for symptoms of anxiety and depression and sense of self-efficacy, as well as a general questionnaire regarding their social situation in general. Statistical analysis included Principal Component Analyses (PCA) and hierarchical multiple regression analysis. RESULTS The PCA revealed a two-factor structure for each of the BMQ-subscales with acceptable (BMQ-G) to high (BMQ-S) internal consistency. The only individual factor that predicted variance in beliefs about medication was patient gender, where levels of both anxiety and depression were elevated in women. CONCLUSION The Swedish BMQ exhibits psychometric features indicating its reliable use in adult PWE. Our results suggest that the BMQ provides information about the patients' view of their medication regardless of their general mood and that women hold stronger beliefs of concern beyond influence from their levels of depression and anxiety.

基于癫痫患者的瑞典版药物信念问卷的验证

标题 基于癫痫患者的瑞典版药物信念问卷的验证。目的 本研究的目的是探索瑞典药物信念问卷 (BMQ) 的潜在结构，调查其可靠性并确定癫痫患者 (PWE) 中个体因素的程度，以及他们的一般信念关于药物，预测他们对特定抗癫痫药物 (ASD) 的看法。方法 156 名研究参与者被诊断患有癫痫症，并进行了完善的神经学随访，完成了一系列评分量表。其中包括瑞典 BMQ，它捕捉关于药物的信念、焦虑和抑郁症状的量表以及自我效能感，以及关于他们一般社会状况的一般问卷。统计分析包括主成分分析（PCA）和分层多元回归分析。结果 PCA 揭示了每个 BMQ 分量表的双因素结构，具有可接受的 (BMQ-G) 到高 (BMQ-S) 内部一致性。预测药物信念差异的唯一个体因素是患者性别，其中女性的焦虑和抑郁水平均升高。结论瑞典 BMQ 表现出心理测量特征，表明其在成人 PWE 中的可靠使用。我们的结果表明，无论患者的总体情绪如何，BMQ 都能提供有关患者对其药物看法的信息，并且女性持有更强烈的关注信念，不受其抑郁和焦虑水平的影响。
