PURPOSE To culturally adapt the Patient-Reported Outcomes Measurement Information System-29 into Thai (T-PROMIS-29) and evaluate the reliability and validity of the culturally adapted questionnaire. METHODS The translation was performed using the Functional Assessment of Chronic Illness Therapy (FACIT) translation guidelines. Unidimensionality, internal consistency, and test-retest reliability at a 1-week interval for the translated measure were computed. Construct validity was evaluated by computing correlations between the T-PROMIS-29 scores and selected SF-36 scale scores. RESULTS The study sample comprised of 241 participants with chronic low back pain. Internal consistencies were good to excellent, with Cronbach's alphas ranging from 0.84 to 0.94. The test-retest stability of all T-PROMIS-29 domains were moderate to good, with ICCs(2,1) ranging from 0.57 to 0.74. Unidimensionality, convergent validity, and divergent construct validity were satisfactory. CONCLUSIONS The findings support the reliability and validity of the T-PROMIS-29 scale scores. The measure can be used to assess key quality of life domains in individuals from Thailand with chronic low back pain.

泰语版《患者报告的结果测量信息系统-29》在慢性下腰痛患者中的跨文化适应性，可靠性和建构效度。

目的在文化上将患者报告的结果测量信息系统-29改编为泰文（T-PROMIS-29），并评估文化适应性调查表的可靠性和有效性。方法使用慢性病治疗功能评估（FACIT）翻译指南进行翻译。计算翻译后的度量在1周间隔内的一维性，内部一致性和重测可靠性。通过计算T-PROMIS-29得分与所选SF-36量表得分之间的相关性来评估构建体的有效性。结果该研究样本包括241名慢性下腰痛参与者。内部一致性好坏，克朗巴赫（Cronbach）的alphas从0.84到0.94。使用ICC，所有T-PROMIS-29域的重测稳定性都中等到良好（2，1）范围从0.57到0.74。单维性，收敛效度和发散构造效度均令人满意。结论研究结果支持了T-PROMIS-29量表评分的可靠性和有效性。该措施可用于评估泰国患有慢性腰背痛的人的生活质量。
