This study aims to develop and validate a German version of French and colleagues' Headache Management Self-efficacy Scale and to construct an abbreviated form for use in behavioral headache research. Furthermore, the contribution of headache-specific self-efficacy to pain-related disability in German chronic headache sufferers was examined.
Headache-specific self-efficacy refers to an individuals' confidence that they can engage in behaviors to either prevent headache episodes or to manage headache-related pain and disability. Self-efficacy beliefs have been shown repeatedly to be positively associated with psychological well-being, effective coping, and enhanced treatment outcomes.
A cross-sectional sample of 304 individuals diagnosed with either migraine, chronic tension-type headache, or a combination of 2 or more headache disorders completed the German Headache Management Self-efficacy Scale and questionnaires assessing headache activity, pain-related coping, general self-efficacy, depression, and anxiety. Responsiveness of the scale was analyzed in a longitudinal subsample of 32 inpatients undergoing headache treatment. Finally, a short form was constructed and evaluated regarding psychometric properties.
The German Headache Management Self-efficacy Scale showed good reliability (Cronbach's α = 0.87) as did the 6-item short form (Cronbach's α = 0.72). In the longitudinal sample, both versions showed a good ability to change over time (SRM= 0.52-1.16). Chronic headache patients with higher levels of self-efficacy reported lower levels of disability (r = -0.26 to -0.31). Multiple regression analyses revealed headache intensity and headache-specific self-efficacy as strongest predictors of headache-related disability (βself-efficacy = -0.21, βintensity = 0.26).
Both the 25-item version and the 6-item version appear to be valid, reliable measures of self-efficacy beliefs. These scales will allow clinicians to identify headache sufferers with low levels of headache-specific self-efficacy with the goal of enhancing this expectancy for improvement. The new short form can help accomplish this goal without adding significantly to the burden of the self-report assessment batteries used in clinical settings.
本研究旨在开发并验证法语及其同事的头痛管理自我效能量表的德语版本，并构建一个简化版用于行为性头痛研究。此外，还考察了头痛特异性自我效能对德国慢性头痛患者疼痛相关残疾的影响。
头痛特异性自我效能是指个体相信自己能够采取行为预防头痛发作或控制与头痛相关的疼痛及残疾。自我效能信念已被反复证明与心理健康、有效应对及更好的治疗效果呈正相关。
对304名被诊断为偏头痛、慢性紧张型头痛或两种或更多头痛疾病组合的个体进行横断面抽样，他们完成了德语头痛管理自我效能量表以及评估头痛活动、疼痛相关应对、一般自我效能、抑郁和焦虑的问卷。在32名接受头痛治疗的住院患者的纵向子样本中分析了该量表的反应性。最后，构建了一个简化版并对其心理测量特性进行了评估。
德语头痛管理自我效能量表显示出良好的信度（克朗巴哈α系数 = 0.87），6项简化版也是如此（克朗巴哈α系数 = 0.72）。在纵向样本中，两个版本都显示出随时间变化的良好能力（标准化反应均值 = 0.52 - 1.16）。自我效能水平较高的慢性头痛患者报告的残疾水平较低（r = -0.26至 -0.31）。多元回归分析显示头痛强度和头痛特异性自我效能是头痛相关残疾的最强预测因素（自我效能β系数 = -0.21，强度β系数 = 0.26）。
25项版本和6项版本似乎都是自我效能信念的有效、可靠测量工具。这些量表将使临床医生能够识别头痛特异性自我效能水平较低的头痛患者，以提高改善的预期。新的简化版有助于实现这一目标，而不会显著增加临床环境中使用的自我报告评估量表的负担。
