As research increasingly examines differences in headache characteristics between Caucasian and African American headache patients, it is requisite to determine the equivalence of existing headache measures for both racial groups.
This study examined the psychometric properties and measurement invariance of four widely used psychosocial headache measures. Caucasians (N = 173) and African Americans (N = 114) receiving treatment in four headache subspecialty clinics throughout Ohio completed the Headache Disability Inventory (HDI), the Migraine-Specific Quality of Life (MSQL) measure, the Headache Management Self-Efficacy (HMSE) scale, and the Headache-Specific Locus of Control (HSLC) scale prior to initiating new preventive therapies.
All measures demonstrated good internal consistency and measurement invariance. Despite adequate measurement invariance, the recommended factor structure of the HMSE scale yielded a poor fit for both African American and Caucasian patients. With perhaps the exception of the HMSE scale, the HDI, MSQL scale and HSLC scale are psychometrically sound and can be used with both Caucasian and African American headache patients.
随着研究越来越多地考察白种人和非裔美国头痛患者头痛特征的差异，确定现有头痛测量方法对这两个种族群体的等效性变得十分必要。
本研究考察了四种广泛使用的心理社会头痛测量方法的心理测量特性和测量不变性。在俄亥俄州四个头痛专科诊所接受治疗的白种人（N = 173）和非裔美国人（N = 114）在开始新的预防性治疗之前，完成了头痛残疾评定量表（HDI）、偏头痛特异性生活质量（MSQL）测量、头痛管理自我效能感（HMSE）量表和头痛特异性控制点（HSLC）量表。
所有测量方法均显示出良好的内部一致性和测量不变性。尽管有足够的测量不变性，但HMSE量表推荐的因子结构对白种人和非裔美国患者的拟合度都很差。除了HMSE量表外，HDI、MSQL量表和HSLC量表在心理测量上是可靠的，可用于白种人和非裔美国头痛患者。
