Locus of control has emerged as an important outcome variable in many health education programs. This study evaluated one instrument designed to measure this construct. Responses to the Parcel-Meyer Children's Health Locus of Control Scale from two groups of sixth grade students were collected to consider fit of the items to the underlying theoretical model and invariance of the finding from different populations. Factor structures from the two groups did not match one another or Levenson's model. Several items did not have any major loadings. Lack of fit and variance of the results is discussed in terms of the items being inappropriate for this age group, since seven and nine of the 20 items had almost no item variance with 90% or more of students responding with the internal answer. Revision of the scale is recommended.
控制点已成为许多健康教育项目中的一个重要结果变量。本研究评估了一种旨在测量这一结构的工具。收集了两组六年级学生对帕塞尔-迈耶儿童健康控制点量表的回答，以考量各项目与潜在理论模型的契合度以及不同人群结果的不变性。两组的因子结构彼此不匹配，也与莱文森模型不匹配。几个项目没有任何主要载荷。鉴于20个项目中有7个和9个项目几乎没有项目方差，90%或更多的学生给出的是内控答案，因此从这些项目不适用于该年龄组的角度讨论了拟合不足和结果差异。建议对该量表进行修订。
