To culturally adapt the self-regulation questionnaire to the Taiwan Chinese version (TC-SRQ) and to evaluate its psychometric properties for gynecologic cancer survivors.
A cross-sectional study was employed with a purposive sample of 287 gynecologic cancer survivors. The TC-SRQ was adapted from a Germany version through back-translation to ensure its quality. For construct validity, confirmatory factor analysis (CFA) was used to assess the TC-SRQ measurement model with fit indexes including the χ test, the root mean square error of approximation (RMSEA), and the normed fit index (NFI), the comparative fit index (CFI), and non-normed fit indices (NNFI). For concurrent validity, the Taiwanese version of the European Organization for Research and Treatment of Cancer's 30-item core quality of life (EORTC QLQ-C30) questionnaire was used as a criterion measure for quality of life (QOL). Reliability was evaluated by internal consistency and test-retest reliability.
For a modified measurement model of TC-SRQ, the model fit (χ = 311.23, P = .0; RMSEA = .088; NFI = .97, CFI = .98, NNFI = .97) was acceptable. The evidence of construct validity of TC-SRQ scale was confirmed by the model estimates. TC-SRQ correlated positively with the global QOL, physical, cognitive, emotional, and social functioning domains, and negatively with fatigue and pain domains of EORTC QLQ-C30. For known groups validity, TC-SRQ was correlated with groups attributed by age, family support, health status, and sleep quality. A Cronbach's α of .91 indicated good internal consistency; the test-retest reliability was .82.
TC-SRQ is a valid and reliable instrument for assessing self-regulation in gynecologic cancer survivors.
将自我调节问卷文化适应为繁体中文版（TC-SRQ），并评估其在妇科癌症幸存者中的心理测量特性。
采用横断面研究，对 287 名妇科癌症幸存者进行了目的性抽样。TC-SRQ 是通过回译从德国版本改编而来，以确保其质量。为了评估结构效度，采用验证性因子分析（CFA）来评估 TC-SRQ 的测量模型，拟合指标包括 χ²检验、近似均方根误差（RMSEA）和标准化拟合指数（NFI）、比较拟合指数（CFI）和非标准化拟合指数（NNFI）。为了评估同时效度，采用欧洲癌症研究与治疗组织的 30 项核心生活质量问卷（EORTC QLQ-C30）的繁体中文版作为生活质量（QOL）的标准衡量标准。信度通过内部一致性和重测信度进行评估。
对于 TC-SRQ 的修正测量模型，模型拟合（χ²=311.23，P=.0；RMSEA=.088；NFI=.97，CFI=.98，NNFI=.97）是可以接受的。TC-SRQ 量表的结构效度证据得到了模型估计的证实。TC-SRQ 与全球 QOL、身体、认知、情感和社会功能领域呈正相关，与 EORTC QLQ-C30 的疲劳和疼痛领域呈负相关。在已知组有效性方面，TC-SRQ 与年龄、家庭支持、健康状况和睡眠质量等因素相关。Cronbach's α 为.91，表明内部一致性良好；重测信度为.82。
TC-SRQ 是评估妇科癌症幸存者自我调节的有效且可靠的工具。
