Further questions need to be addressed in the evaluation of locus of control (LOC) in headaches, such as reducing scale length and adapting them to diverse cultural environments, as in the case of Spain.
We perform a confirmatory factor analysis of the most outstanding items contained in the Headache-Specific Locus of Control Scale in the responses of 118 patients suffering from headaches who received assistance at public health care centers in the province of Seville (Spain).
The adjustment was positive, thus confirming the original structure of 3 factors: internal locus of control (LOC-I), health care professionals' LOC, and chance locus of control (LOC-C). Scale validation was performed by examining associations both with headache clinical parameters and psychological measures. The latter included self-efficacy, internal language, coping strategies, and pain behaviors. LOC-C results deserve special mention, supporting the idea that it seems more important to avoid that patients develop LOC-C rather than boosting LOC-I and LOC-P expectations.
The so-called Headache-Specific Locus of Control Scale-Short Form 9 has turned out to be a parsimonious (9 items), valid, and reliable measure of headache LOC.
在头痛患者中评估控制源（LOC）时，还需要解决进一步的问题，例如减少量表的长度并使其适应不同的文化环境，就像西班牙的情况一样。
我们对在塞维利亚省（西班牙）公共卫生保健中心接受治疗的 118 名头痛患者的反应中包含的最突出的项目进行了头痛特异性控制源量表的验证性因子分析。
调整后的结果是积极的，因此证实了原有的 3 个因素结构：内部控制源（LOC-I）、医疗保健专业人员的 LOC 和机会控制源（LOC-C）。通过检查与头痛临床参数和心理测量的关联来进行量表验证。后者包括自我效能、内部语言、应对策略和疼痛行为。LOC-C 的结果值得特别提及，它支持这样一种观点，即避免患者产生 LOC-C 似乎比增强 LOC-I 和 LOC-P 的期望更为重要。
所谓的头痛特异性控制源量表-简短形式 9 已被证明是一种简洁（9 项）、有效且可靠的头痛 LOC 测量工具。
