We studied the ability of headache history, a 4-week headache diary, standard psychological tests, and laboratory measures of psychophysiologic responses to stress to predict the outcome of relaxation therapy and biofeedback for three types of chronic headache. Using canonical discriminant function analyses, each potential predictor set was tested separately, and all four were tested together. Information from the headache history alone correctly classified 89 to 95% of patients as improved or unimproved. No other single predictor set was consistently better than headache history. When all four predictor sets were combined, prediction improved; 93 to 100% of patients were correctly classified.
我们研究了头痛病史、为期4周的头痛日记、标准心理测试以及压力的心理生理反应的实验室测量指标预测三种慢性头痛的放松疗法和生物反馈疗法结果的能力。使用典型判别函数分析，分别对每个潜在预测指标集进行测试，并对所有四个指标集进行综合测试。仅根据头痛病史就能正确地将89%至95%的患者分类为病情改善或未改善。没有其他单一预测指标集始终优于头痛病史。当将所有四个预测指标集结合起来时，预测效果有所改善；93%至100%的患者被正确分类。
