本研究的主要目的是估计精神疾病患者需要多少次心理治疗才能恢复正常的功能状态或可靠地改善。这将有助于治疗计划和政策决定，多少治疗是足够的。在两所大学的培训诊所中，125名患者接受心理治疗的进展情况被采用自然主义设计逐期跟踪。恢复和可靠的改善是用于估计满足标准所需的每周治疗次数的生存分析中感兴趣的双项事件。使用生存分析，估计50%的患者需要8次治疗才能显示可靠的改善，而85%的患者需要21次治疗才能满足这一标准。恢复需要更多的治疗，50%的客户估计在14次治疗后恢复，70%需要23次治疗。根据目前的结果，我们得出结论，澳大利亚政府在公共和私营部门关于客户进入心理治疗以显示效益所需的会议次数的现行政策远远少于实际上必要的政策。目前的研究结果与其他地方的研究结果大致一致，并建议最低益处应该接近20次。目前的政策似乎只适用于大约三分之一有心理疾病负担的客户。
The principle aim of this study was to estimate the number of sessions of psychotherapy needed for clients suffering from psychiatric illness to return to a normal state of functioning or reliably improve. This would be helpful for treatment planning and policy decisions regarding how much therapy is enough. The progress of 125 clients entering psychological treatment in two university training clinics was tracked on a session-by-session basis using a naturalistic design. Recovery and reliable improvement were the bi-nomial events of interest used in a survival analysis that estimated the number of weekly treatment sessions needed to meet criteria. Using survival analysis it was estimated that it would take about 8 sessions for 50% of clients to show reliable improvement and 21 sessions for about 85% to meet this criterion. Recovery took more treatment, with 50% of clients estimated to recover after 14 sessions and 70% requiring 23. On the basis of the present results we conclude that the present policy of the Australian Government in both the public and private sector regarding the number of sessions needed for clients entering psychological treatments to show a benefit is much less than is, in fact, necessary. The findings of the current study are roughly consistent with those found elsewhere and suggest a minimum benefit should be closer to 20 sessions. The current policy appears to be suitable for only about one-third of clients who carry the burden of psychological illness.
