A comprehensive assessment of patient hesitancy to use analgesics and accurate knowledge related to the promotion of analgesic adherence is necessary for effective pain management. Unfortunately, there has been a lack of a short and concise questionnaire to assess patients' hesitancy to use analgesics in clinical practice.
This paper is a report of the development and psychometric properties of the short version of the Barriers Questionnaire-Taiwan form (S-BQT).
This study employed a descriptive design.
A convenience sample was recruited from oncology clinics at two medical centers in Taiwan.
One hundred and eighty-three (N=183) patients receiving analgesics for cancer pain participated in the study.
Instruments included the Barriers Questionnaire-Taiwan form (BQT), the Taiwanese version of the Morisky Medication Adherence Measure-Taiwan form (MMAM-T). Two self-administered questionnaires were performed at the same time, and the ratio of analgesic usage was computed over a two-week period. Reliability was established by calculating Cronbach's α and test-retest reliability. The validity was estimated by construct validity, criterion-related validity, and known group validity.
To develop the S-BQT, we used reliability analysis to extract nine items from nine subscales. Internal consistency of the S-BQT was indicated by a Cronbach's alphas score of 0.86. Test-retest reliability was assessed as 0.83 over a two-week interval. Factor analysis revealed two factor structures. Criterion-related validity was examined by correlating the S-BQT score, and MMAM-T score, and the ratio of analgesic use. Known group validity was examined by comparing the S-BQT scores of patients with hesitancy to report pain and take analgesics vs. patients demonstrating no such hesitancy in the previous week. Known group validity was also established by comparing the S-BQT scores among patients with low, moderate, and high adherence to the usage of medication.
The S-BQT shows excellent reliability and validity. The use of this instrument can help to improve communication between patients and clinicians regarding the use of analgesics in the management of pain.
全面评估患者对使用镇痛药的犹豫程度和准确了解促进镇痛药物依从性的相关知识，对于有效的疼痛管理至关重要。然而，在临床实践中，缺乏一种简短而简洁的问卷来评估患者对使用镇痛药的犹豫程度。
本文报告了简短版台湾版障碍问卷（S-BQT）的开发和心理测量特性。
本研究采用描述性设计。
在台湾的两家医疗中心的肿瘤诊所招募了方便样本。
183 名正在接受癌症疼痛镇痛治疗的患者参与了研究。
研究工具包括台湾版障碍问卷（BQT）和台湾版 Morisky 药物依从性测量问卷（MMAM-T）。同时进行了两份自我管理问卷，在两周内计算镇痛药的使用比例。通过计算 Cronbach's α 和重测信度来确定信度。通过结构效度、效标关联效度和已知组效度来评估效度。
为了开发 S-BQT，我们使用可靠性分析从九个子量表中提取了九个项目。S-BQT 的内部一致性通过 Cronbach's α 值为 0.86 来表示。在两周的间隔内，重测信度评估为 0.83。因子分析显示了两种因素结构。通过与 S-BQT 得分、MMAM-T 得分和镇痛药使用比例相关来检验效标关联效度。通过比较有报告疼痛和使用镇痛药犹豫与上周无此类犹豫的患者的 S-BQT 得分来检验已知组的有效性。还通过比较低、中、高药物使用依从性患者的 S-BQT 得分来确定已知组的有效性。
S-BQT 具有良好的信度和效度。使用该工具可以帮助改善患者与临床医生在疼痛管理中使用镇痛药方面的沟通。
