Martin and colleagues have described their development of a Headache-Specific Locus of Control scale (HSLC) which contains 11 items for each of its three subscales: internal, health care professional, and chance orientations. In this replication study, we gathered data from patients who came to a Headache Clinic in a medical center (n = 151) and from a comparison sample (n = 192). Factor analysis and alpha coefficients were similar to those reported by Martin. Only small correlations were found between the subscale scores although some of them were statistically significant. This suggests that the HSLC is a psychometrically competent instrument. Additionally, mean scores of its three subscales differentiated the patient population from those whose headaches were less severe and thus did not seek help.
马丁及其同事描述了他们开发的头痛特异性控制点量表（HSLC），该量表的三个子量表（内控、医疗保健专业人员和机遇取向）各包含11个项目。在这项重复研究中，我们收集了来自一家医疗中心头痛诊所的患者（n = 151）以及一个对照样本（n = 192）的数据。因子分析和阿尔法系数与马丁报告的结果相似。虽然部分子量表得分之间的相关性具有统计学意义，但仅发现了较小的相关性。这表明HSLC是一种心理测量性能良好的工具。此外，其三个子量表的平均得分区分了患者群体与头痛症状较轻因而未寻求帮助的人群。
