The purpose of the study is to test the cross-cultural adaptation and psychometric properties of a Danish version of the Headache-Specific Locus of Control Scale (HSLC) and the Headache Management Self-Efficacy Scale (HMSE) in a tertiary headache centre. HSLC and HMSE are headache-specific measures of locus of control (LOC) and SE. The Danish versions of the HSLC and the HMSE were created according to the guidelines for cross-cultural adaptation of self-report measures. The HSLC and HMSE were administered to 135 consecutively referred headache patients in a tertiary headache centre together with other self-report measures concerning general distress, anxiety, depression, and health-related quality of life. Internal stability of the HSLC subscales and the HMSE were analysed using Chronbach's alpha coefficient. The psychometric properties of the Danish version of the HSLC and the HMSE were analysed using Spearman's rank correlation test. Cronbach's alpha ranged from 0.71 to 0.88 and the corrected item-total correlations were acceptable. The mean corrected item-total correlations for the three subscales of HSLC (health-care LOC, internal LOC, and chance LOC) were 0.40, 0.59, and 0.40 respectively. The mean corrected item-total correlation for HMSE was 0.42. High HMSE scores were found to be associated with high scores on internal LOC and low scores on chance LOC. High scores on chance LOC were positively associated with low scores on social functioning independently of headache frequency. The results are consistent with the earlier findings of the original American versions of HMSE and HSLC. These scales seem to be valid and valuable tools for testing of psychological aspects related to level of functioning and quality of life for headache patients across different cultures of Western society. The HMSE and the HSLC proved valuable in clinical headache research. Since scores on HSLC and HMSE were associated with measures of physical and social functioning the HSLC and HMSE may be of particular interest for intervention studies aimed at enhancing level of functioning for headache patients.
本研究的目的是在一家三级头痛中心测试丹麦版头痛特异性控制点量表（HSLC）和头痛管理自我效能量表（HMSE）的跨文化适应性及心理测量特性。HSLC和HMSE是针对头痛的控制点（LOC）和自我效能（SE）的测量工具。HSLC和HMSE的丹麦版是根据自我报告测量工具跨文化适应性的指导方针编制的。在一家三级头痛中心，对135名连续转诊的头痛患者施测了HSLC和HMSE，同时还施测了其他有关一般痛苦、焦虑、抑郁及健康相关生活质量的自我报告测量工具。使用克朗巴赫α系数分析HSLC分量表和HMSE的内部稳定性。使用斯皮尔曼等级相关检验分析丹麦版HSLC和HMSE的心理测量特性。克朗巴赫α系数范围为0.71至0.88，校正后的项目-总分相关性可以接受。HSLC三个分量表（医疗保健LOC、内部LOC和机遇LOC）的平均校正项目-总分相关性分别为0.40、0.59和0.40。HMSE的平均校正项目-总分相关性为0.42。发现HMSE高分与内部LOC高分及机遇LOC低分相关。机遇LOC高分与社会功能低分呈正相关，且与头痛频率无关。研究结果与原始美国版HMSE和HSLC的早期研究结果一致。这些量表似乎是用于测试西方社会不同文化中头痛患者功能水平和生活质量相关心理方面的有效且有价值的工具。HMSE和HSLC在临床头痛研究中被证明是有价值的。由于HSLC和HMSE的得分与身体和社会功能的测量相关，因此HSLC和HMSE可能对旨在提高头痛患者功能水平的干预研究特别有意义。
