最近的研究表明，认知行为疗法（CBT）可以显著改善严重精神健康问题患者的预后。然而，没有专门设计的工具来评估向精神病患者提供CBT的能力。本研究探讨了精神病认知治疗量表（CTS-Psy）用于评估精神病患者CBT质量的心理测量学特性。采用以CBT为导向的精神病培训课程的学员进行录音治疗，调查了使用CTS-Psy的训练评定者的评定者间信度。效度是通过测试量表可用于评估一系列治疗师能力和患者严重程度的程度，以及通过评估CTS-Psy在9个月的培训课程中可以拾取技能习得变化的程度来调查的。CTS-Psy在能够对所研究样本中的所有治疗标准和所有类型的患者会话进行评分方面表现出出色的评分者间信度和良好的效度。此外，该量表对培训课程期间临床技能的变化很敏感，可以区分接受过培训和未接受培训的人。
Recent research suggests that cognitive-behaviour therapy (CBT) can significantly improve outcomes for patients with severe mental health problems. However, there are no tools specifically designed to assess competence in delivering CBT to psychotic patients. This study investigates the psychometric properties of the Cognitive Therapy Scale for Psychosis (the CTS-Psy) for assessing the quality of CBT with psychotic patients. Inter-rater reliability of trained raters using the CTS-Psy was investigated using taped therapy of trainees engaged in a CBT oriented psychosis training course. Validity was investigated in relation to examining the degree to which the scale could be used to assess a range of therapist ability and patient severity and by assessing the degree to which the CTS-Psy could pick up changes in skill acquisition during the training course over a 9-month period. The CTS-Psy demonstrated excellent inter-rater reliability and good validity in relation to it being able to rate all standards of therapy and all types of patient sessions in the sample studied. In addition, the scale was sensitive to changes in clinical skills during a training course and could discriminate between those who had received training and those who had not.
