A prospective controlled study of acute low back pain in general practice was carried out. The presence of psychiatric illness was measured by use of the general health questionnaire (GHQ), by clinical assessment, and personality factors by use of the Eysenck personality inventory (EPI). It was found that overall the amount of psychiatric illness did not differ between patients with back pain and their controls at the time of presentation, although there was a higher prevalence of previous psychiatric illness in the back-pain group. The only difference in the personality factors measured was a higher degree of extraversion in the back-pain patients.
在普通医疗实践中开展了一项关于急性腰痛的前瞻性对照研究。通过使用一般健康问卷（GHQ）来衡量精神疾病的存在情况，通过临床评估来判断，同时使用艾森克人格量表（EPI）来评估人格因素。研究发现，总体而言，在就诊时，背痛患者及其对照组之间的精神疾病数量没有差异，尽管背痛组中既往精神疾病的患病率较高。所测量的人格因素中唯一的差异是背痛患者的外向程度更高。
