Applicants for outpatient psychotherapy completed a symptom checklist that permitted evaluation of the duration, intensity, and patterning of presenting symptoms. Random assignment of patients acceptable for psychotherapy to immediate treatment or to the waiting list resulted in two comparable groups who repeated the symptom checklist after an average interval nine months. Patients in psychotherapy showed a greater reduction in average intensity of all symptoms than was observable in the waiting list group. In the waiting list group, improvements tended to be limited to those patients whose conditions were of comparatively brief duration. In the psychotherapy group, improvements of chronic patients were frequent; however, improvements tended to occur among those patients reporting some new symptoms rather than those giving no evidence of exacerbation. A predmoninance of "neurotic" over "behavioral" complaints also appeared to be predictive of a positive response to psychotherapy.
门诊心理治疗的申请者完成了一份症状清单，该清单允许对呈现症状的持续时间、强度和模式进行评估。将可接受心理治疗的患者随机分配到立即治疗组或等待名单组，结果形成了两个可比组，这两组在平均九个月的间隔后再次填写症状清单。接受心理治疗的患者在所有症状的平均强度上比等待名单组有更大程度的减轻。在等待名单组中，改善往往仅限于病情持续时间相对较短的患者。在心理治疗组中，慢性病患者经常出现改善；然而，改善往往发生在报告有一些新症状的患者中，而不是那些没有病情加重迹象的患者。“神经症性”主诉比“行为性”主诉占优势似乎也预示着对心理治疗有积极反应。
