BACKGROUND
Low back pain (LBP) is a top musculoskeletal problem and a substantial cause of socioeconomic burden internationally. The STarT Back Screening Tool (SBST) is a useful screening tool to manage patients with LBP but it is unavailable in Thai. Therefore, the aims of this study were to translate and cross-culturally adapt the SBST into a Thai version (SBST-TH) and validate its psychometric properties (e.g., factor analysis, internal consistency, test-retest reliability, agreement, convergent validity and discriminative validity).
METHODS
Translation and cross-cultural adaptation of the SBST into Thai version were conducted according to standard guidelines. A total of 200 participants with non-specific LBP were invited to complete the SBST, visual analogue scale for pain intensity, Roland-Morris disability questionnaire (RMDQ), fear-avoidance beliefs questionnaire, pain catastrophising scale, hospital anxiety and depression scale and the EuroQol five-dimensional questionnaire. Thirty participants completed the SBST-TH twice with an interval of 48 h to evaluate test-retest reliability.
RESULTS
Factor analysis demonstrated two (physical and psychological) components for the SBST-TH (39.38% of the total variance). The Cronbach's alpha (0.86 for total score and 0.76 for psychosocial subscore) represent satisfactory internal consistency. The acceptability of intraclass correlation coefficient was found in the total (0.73) and subscore (0.79). The areas under the curve (AUC) for the total score ranged 0.67-0.85 and 0.66-0.75 for subscore. The excellent discriminative validity was observed (AUC = 0.85, 95% confidence interval = 0.72, 0.97) between the total score of the SBST-TH and disability (RMDQ). Spearman's correlation coefficients represented moderate to strong correlation (0.32-0.56) between the SBST-TH and all questionnaires. The findings suggest a good relationship between the SBST-TH and disability and quality of life. Owing to the results from the convergent and discriminative validity, construct validity of the SBST-TH can be supported. The minimal detectable changes of the total score and subscore were 2.04 and 1.60, respectively. Significant floor and ceiling effects were not found in the SBST-TH.
CONCLUSION
The SBST-TH was successfully translated and adapted. It is a valid and reliable tool to classify Thai patients with non-specific LBP into low, moderate and high risks for chronicity.

背景
腰痛是首要的肌肉骨骼问题，在国际上是社会经济负担的一个重要原因。STarT Back筛查工具（SBST）是管理腰痛患者的一种有用筛查工具，但泰语版不可用。因此，本研究的目的是将SBST翻译并进行跨文化改编为泰语版（SBST-TH），并验证其心理测量学特性（如因子分析、内部一致性、重测信度、一致性、收敛效度和区分效度）。
方法
根据标准指南将SBST翻译并跨文化改编为泰语版。共邀请200名非特异性腰痛患者完成SBST、疼痛强度视觉模拟量表、罗兰-莫里斯残疾问卷（RMDQ）、恐惧回避信念问卷、疼痛灾难化量表、医院焦虑抑郁量表和欧洲五维健康量表。30名参与者间隔48小时完成两次SBST-TH以评估重测信度。
结果
因子分析显示SBST-TH有两个（身体和心理）成分（占总方差的39.38%）。克朗巴哈系数（总分0.86，心理社会子分0.76）表示内部一致性良好。组内相关系数在总分（0.73）和子分（0.79）方面可接受。总分的曲线下面积（AUC）范围为0.67 - 0.85，子分的曲线下面积范围为0.66 - 0.75。在SBST-TH总分与残疾（RMDQ）之间观察到良好的区分效度（AUC = 0.85，95%置信区间 = 0.72，0.97）。斯皮尔曼相关系数表示SBST-TH与所有问卷之间存在中度至高度相关性（0.32 - 0.56）。研究结果表明SBST-TH与残疾和生活质量之间存在良好关系。由于收敛效度和区分效度的结果，可以支持SBST-TH的结构效度。总分和子分的最小可检测变化分别为2.04和1.60。在SBST-TH中未发现明显的地板效应和天花板效应。
结论
SBST-TH已成功翻译和改编。它是一种有效且可靠的工具，可将泰国非特异性腰痛患者分为慢性低、中、高风险。
