Tallies were made of outcomes of all resonably controlled comparisons of psychotherapies with each other and with other treatments. For comparisons of psychotherapy with each other, most studies found insignificant differences in proportions of patients who improved (though most patients benefited). This "tie score effect" did not apply to psychotherapies vs psychopharmacotherapies compared singly-psychotherapies did better. Combined treatments often did better than single treatments. Among the comparisons, only two specially beneficial matches between type of patient and type of treatment were found. Our explanations for the usual tie score effect emphasize the common components among psychotherapies, especially the helping relationship with a therapist. However, we believe the research does not justify the conclusion that we should randomly assign patients to treatments-research results are usually based on amount of improvement; "amount" may not disclose differences in quality of improvement from each treatment.
对心理治疗彼此之间以及与其他治疗方法进行的所有合理对照比较的结果进行了统计。在心理治疗相互比较中,大多数研究发现改善患者比例的差异不显著(尽管大多数患者都从中受益)。这种“平局分数效应”不适用于单独比较心理治疗与心理药物治疗——心理治疗效果更好。联合治疗通常比单一治疗效果更好。在这些比较中,仅发现了两种患者类型与治疗类型之间特别有益的匹配情况。我们对通常的平局分数效应的解释强调了心理治疗之间的共同要素,尤其是与治疗师的帮助关系。然而,我们认为该研究并不足以得出应将患者随机分配至各种治疗方法的结论——研究结果通常基于改善程度;“程度”可能无法揭示每种治疗方法在改善质量上的差异。
