This report describes the development and psychometric testing of the Systems Thinking Scale for Adolescent Behavior Change (STS-AB). Following item development, initial assessments of understandability and stability of the STS-AB were conducted in a sample of nine adolescents enrolled in a weight management program. Exploratory factor analysis of the 16-item STS-AB and internal consistency assessments were then done with 359 adolescents enrolled in a weight management program. Test-retest reliability of the STS-AB was .71, p = .03; internal consistency reliability was .87. Factor analysis of the 16-item STS-AB indicated a one-factor solution with good factor loadings, ranging from .40 to .67. Evidence of construct validity was supported by significant correlations with established measures of variables associated with health behavior change. We provide beginning evidence of the reliability and validity of the STS-AB to measure systems thinking for health behavior change in young adolescents.
本报告描述了青少年行为改变系统思维量表（STS - AB）的开发及心理测量测试。在项目开发之后，对参加体重管理项目的9名青少年样本进行了STS - AB可理解性和稳定性的初步评估。随后，对参加体重管理项目的359名青少年进行了16项STS - AB的探索性因素分析和内部一致性评估。STS - AB的重测信度为0.71，p = 0.03；内部一致性信度为0.87。对16项STS - AB的因素分析表明为单因素解决方案，具有良好的因素负荷，范围从0.40至0.67。与健康行为改变相关变量的既定测量方法的显著相关性支持了结构效度的证据。我们提供了初步证据，证明STS - AB在测量青少年健康行为改变的系统思维方面具有可靠性和有效性。
