This study involved the design and evaluation of the High-Intensity Interval Training Self-Efficacy Questionnaire (HIIT-SQ). Phase 1: Questionnaire items were developed. Phase 2: Australian adolescents (N = 389, 16.0 ± 0.4 years, 41.10% female) completed the HIIT-SQ, and factorial validity of the measurement model was explored. Phase 3: Adolescents (N = 100, age 12-14 years, 44% female) completed the HIIT-SQ twice (1 week apart) to evaluate test-retest reliability. Confirmatory factor analysis of the final six items (mean = 3.43-6.73, SD = 0.99-25.30) revealed adequate fit, χ2(21) = 21, p = .01, comparative fit index = .99, Tucker-Lewis index = .99, root mean square of approximation = .07, 90% confidence interval [.04, .11]. Factor loading estimates showed that all items were highly related to the factor (estimates range: 0.81-0.90). Intraclass coefficients and typical error values were .99 (95% confidence interval [.99, 1.00]) and .22, respectively. This study provides preliminary evidence for the validity and reliability of scores derived from the HIIT-SQ in adolescents.
本研究涉及高强度间歇训练自我效能量表（HIIT-SQ）的设计与评估。第一阶段：编制问卷项目。第二阶段：澳大利亚青少年（N = 389，16.0±0.4岁，41.10%为女性）完成HIIT-SQ，并探索测量模型的因子效度。第三阶段：青少年（N = 100，年龄12 - 14岁，44%为女性）两次完成HIIT-SQ（间隔1周）以评估重测信度。对最终的六个项目（均值 = 3.43 - 6.73，标准差 = 0.99 - 25.30）进行验证性因素分析，结果显示拟合良好，χ2(21) = 21，p = .01，比较拟合指数 = .99，塔克 - 刘易斯指数 = .99，近似均方根 = .07，90%置信区间[.04, .11]。因子载荷估计表明所有项目与该因子高度相关（估计范围：0.81 - 0.90）。组内相关系数和典型误差值分别为.99（95%置信区间[.99, 1.00]）和.22。本研究为HIIT-SQ在青少年中得分的效度和信度提供了初步证据。
