Treated chronic low back pain patients (N = 102) in a university hospital clinic. Ss were given the EPI, the Recent LIfe Changes Questionnaire, and the Locus of Control Scale in order to isolate the principal dimensions of emotional disturbance in such patients and to see whether derived dimensions were related to response to conservative treatment for back pain. Self-report ratings of current pain intensity were obtained approximately 1 year after the start of treatment. Factor analysis revealed five factors: Distrust and alienation, somatic concern, vulnerability, extraversion, and social desirability; these accounted for 71% of the total variance among patients. Patients with above-average pretreatment distrust and alienation scores more frequently failed to return the follow-up form than patients with below-average scores. Low scores on somatic concern were related to good outcome. Results suggest that patients in alienation and distrust may be prone to be poor compliers. Because only the somatic concern dimension predicted outcome, a single scale that measures this characteristic may be sufficient for effective identification of the potential good vs. poor responders to conservative treatment of low back pain.
在一家大学医院诊所对102名慢性下背痛患者进行了治疗。受试者接受了艾森克人格问卷（EPI）、近期生活变化问卷和控制点量表测试，以分离出这类患者情绪障碍的主要维度，并观察所导出的维度是否与背痛保守治疗的反应相关。在治疗开始约1年后获得了当前疼痛强度的自我报告评分。因子分析揭示了五个因素：不信任与疏离、躯体关注、易感性、外向性和社会赞许性；这些因素占患者总方差的71%。治疗前不信任和疏离得分高于平均水平的患者比得分低于平均水平的患者更频繁地未返回随访表格。躯体关注得分低与良好的治疗结果相关。结果表明，处于疏离和不信任状态的患者可能容易成为依从性差的人。由于只有躯体关注维度预测了治疗结果，因此一个测量该特征的单一量表可能足以有效地识别对下背痛保守治疗潜在的良好与不良反应者。
