目的：为了开发和验证一个问卷，以筛选潜在的不遵守慢性疾病patients with chronic illness.Methods：定性访谈的主题与慢性阻塞性肺疾病患者被用于开发问卷的内容。该问卷分发给525名患有慢性肺部疾病的门诊患者。进行主成分分析，以确定问卷中的分量表。内部的一致性，效度和稳定性的分量表也evaluated.Results：30项信念和行为问卷（BBQ）措施的信念，经验和遵守行为的五点Likert型量表。280例患者（53.3%）回答了问卷，平均年龄为71.1岁。“信念”部分有两个因素的解决方案-“信心”和“关注”，内部权重分别为0.82和0.45。从“体验”部分确定的两个领域-满意度和失望度分别为0.85和0.52。“行为”部分单独命名为“依从性行为筛查工具”（TABS），有一个双因素解决方案-“依从性”和“不依从性”，内部可接受性分别为0.80和0.59。所有领域在两个不同的患者人群中表现出相当的可靠性。时间稳定性在0.62 ~ 0.94之间。结论：BBQ量表和TABS量表的效度、信度和实用性均较好。BBQ和TABS在临床实践和研究中筛选依从性信念，经验和行为方面具有潜在的应用。(c)2005爱思唯尔爱尔兰有限公司保留所有权利。
Objective: To develop and validate a questionnaire to screen for potential nonadherence in patients with chronic ailments.Methods: Themes from qualitative interviews with chronic obstructive pulmonary disease patients were used in developing content of the questionnaire. The questionnaire was distributed to 525 ambulatory patients with chronic lung diseases. Principal components analysis was performed to identify the subscales in the questionnaire. Internal consistency, validity and stability of the subscales were also evaluated.Results: The 30-item Beliefs and Behaviour Questionnaire (BBQ) measures beliefs, experiences and adherent behaviour on five-point Likert-type scales. Two hundred and eighty patients (53.3%) with a mean age of 71.1 years responded to the questionnaire. The 'beliefs' section had a two-factor solution-'confidence' and 'concerns' with internal consistencies of 0.82 and 0.45, respectively. The two domains identified from the section 'experiences'-satisfaction' and 'disappointment' had internal consistencies of 0.85 and 0.52, respectively. The 'behaviour' section, separately entitled the Tool for Adherence Behaviour Screening (TABS), had a two-factor solution-'adherence' and 'nonadherence', with internal consistencies of 0.80 and 0.59, respectively. All the domains demonstrated comparable reliabilities across two different patient populations. Their temporal stabilities ranged between 0.62 and 0.94.Conclusion: The validity, reliability and utility of the BBQ and the TABS, a sub-scale of the BBQ that screens both intentional and unintentional nonadherence to pharmacological and non-pharmacological disease management, have been established.Practice implications: The BBQ and the TABS have potential applications in screening adherence beliefs, experiences and behaviour in both clinical practice and research.
