The Boston Carpal Tunnel Questionnaire (BCTQ) is a widely recommended patient-reported outcome measure to evaluate symptoms and functions in carpal tunnel syndrome (CTS) patients. We aimed to evaluate the translation and cross-cultural adaptation of the Thai version of the BCTQ (Thai BCTQ) and to investigate the psychometric properties including internal consistency, test-retest reliability, construct validity and responsiveness.
The Thai BCTQ was field tested with 15 healthy volunteers and 15 CTS patients to evaluate the item-objective congruence of each item. Following that, one hundred and twenty-four CTS patients were included for psychometric evaluation in this study. Internal consistency was assessed using Cronbach's alpha. Test-retest reliability was examined using the intraclass correlation coefficient (ICC). To evaluate construct validity, Spearman's rank correlation of the symptom severity scale (Thai BCTQ -S), the functional status scale (Thai BCTQ -F) and the subscales of the Thai MHQ were analyzed. Responsiveness was determined using the standardized response mean (SRM).
Minor modification of the Thai version was made to better explain the term "tingling". The Thai BCTQ-S, Thai BCTQ-F and Thai BCTQ demonstrated adequate Cronbach's alpha values (0.91-0.94) and good test-retest reliability (ICC=0.89-0.98). Regarding related dimensions, a strong correlation (=0.67, <0.008) was found between the Thai BCTQ-F and the Function subscale of Thai MHQ as well as between Thai BCTQ-F and the Activities of Daily Living subscale of the Thai MHQ (=0.75, <0.008). In unrelated dimensions, there was a relatively weak correlation between the Thai BCTQ-S and the Aesthetics subscale of the Thai MHQ (r=0.32, =0.0116). The SRM of the Thai BCTQ was 1.46, indicating large responsiveness.
The Thai BCTQ has adequate internal consistency in both the symptom and function scales as well as good construct validity and test-retest reliability indicating it is suitable for evaluating Thai CTS patients. This tool also has a high ability to detect clinically significant changes in symptoms and function over time after receiving conservative or surgical treatment.
波士顿腕管综合征问卷（BCTQ）是一种广泛推荐的患者报告结局指标，用于评估腕管综合征（CTS）患者的症状和功能。我们旨在评估泰语版BCTQ（泰语BCTQ）的翻译和跨文化适应性，并研究其心理测量特性，包括内部一致性、重测信度、结构效度和反应度。
对15名健康志愿者和15名CTS患者进行泰语BCTQ的现场测试，以评估每个条目的条目与目标的一致性。在此之后，本研究纳入了124名CTS患者进行心理测量评估。使用Cronbach's α评估内部一致性。使用组内相关系数（ICC）检查重测信度。为了评估结构效度，分析了症状严重程度量表（泰语BCTQ-S）、功能状态量表（泰语BCTQ-F）与泰语MHQ各子量表之间的Spearman等级相关性。使用标准化反应均值（SRM）确定反应度。
对泰语版进行了微小修改，以更好地解释“刺痛”一词。泰语BCTQ-S、泰语BCTQ-F和泰语BCTQ显示出足够的Cronbach's α值（0.91 - 0.94）和良好的重测信度（ICC = 0.89 - 0.98）。在相关维度方面，泰语BCTQ-F与泰语MHQ的功能子量表之间以及泰语BCTQ-F与泰语MHQ的日常生活活动子量表之间发现了强相关性（r = 0.67，P < 0.008）。在不相关维度方面，泰语BCTQ-S与泰语MHQ的美学子量表之间存在相对较弱的相关性（r = 0.32，P = 0.0116）。泰语BCTQ的SRM为1.46，表明反应度大。
泰语BCTQ在症状和功能量表方面具有足够的内部一致性，以及良好的结构效度和重测信度，表明它适用于评估泰国CTS患者。该工具还具有较高的能力来检测接受保守或手术治疗后症状和功能随时间的临床显著变化。
