The Outcome Questionnaire-45 (OQ-45; Lambert et al., ) has been designed for frequent assessment of a patient's functioning during the course of psychotherapy and has become one of the most frequently used outcome measures in the Netherlands. The OQ-45 was originally normed on outpatients in secondary care only, but is applied in a wide variety of patient populations. As such, it has become increasingly important to provide cut-off scores with the normal population, as well as between different patient populations. The present large-scale Dutch study aims to provide cut-off scores between several populations. Data were collected from the normal population (n = 1810) and patients in five different treatment settings: outpatient primary care (n = 1581), outpatient secondary care (n = 9433), private practice (n = 457), day patient (n = 481) and inpatient therapies (n = 485), a total of more than 14.000 administrations. Reliable change indices and cut-off scores were calculated using the method of Jacobson and Truax (). The reliable change index for the patient population was calculated as 18 and the cut-off between the normal and patient population as 56. Sensitivity, specificity and area under the curves of cut-off scores between the normal population and the treatment settings were satisfactory and generally higher than 0.80. Between the patient populations, these measures were generally too low for strict use. The OQ-45 total score can satisfactorily discriminate between the normal and patient populations. For assignment to specific treatment types, the OQ-45 may help, but its use is somewhat limited in practice. Copyright © 2015 John Wiley & Sons, Ltd.
The Dutch OQ-45 has satisfactory levels of reliability, sensitivity, specificity and area under the curve. The new overall cut-off score for normal function for the Dutch OQ-45 is 56 and the new reliable change index is 18. Cut-off scores for several therapeutic treatments are provided.
结果问卷-45(OQ-45;兰伯特等人)旨在在心理治疗过程中频繁评估患者的功能状况,已成为荷兰使用最频繁的结果测量工具之一。OQ-45最初仅以二级护理门诊患者为常模,但现在应用于各种各样的患者群体。因此,提供与正常人群以及不同患者群体之间的分界值变得越来越重要。目前这项大规模的荷兰研究旨在提供不同人群之间的分界值。数据收集自正常人群(n = 1810)以及五种不同治疗环境中的患者:门诊初级护理(n = 1581)、门诊二级护理(n = 9433)、私人诊所(n = 457)、日间患者(n = 481)和住院治疗(n = 485),总共进行了超过14000次施测。使用雅各布森和特鲁克斯的方法计算了可靠变化指数和分界值。患者群体的可靠变化指数计算为18,正常人群与患者群体之间的分界值为56。正常人群与各治疗环境之间分界值的敏感性、特异性和曲线下面积令人满意,一般高于0.80。在不同患者群体之间,这些指标通常过低,无法严格使用。OQ-45总分能够令人满意地区分正常人群和患者群体。对于分配到特定治疗类型,OQ-45可能会有所帮助,但在实际应用中其用途有些有限。版权所有© 2015约翰·威利父子有限公司。
