测量对精神分裂症结局的偏好有助于有意义地整合多个结局指标和治疗结局的多个观点。时间权衡（TTO）技术，专门用于测量健康状态的偏好，被广泛用于健康研究，但一些证据表明，TTO可能不太适合精神分裂症比其他健康状况。本研究验证了以下假设，即根据精神分裂症的病程调整标准TTO的时间范围并简化其表述将提高其可行性和效率。40名临床医生使用4种时间范围和呈现格式组合中的1种提供了TTO评级。数字评级和定量和定性的可行性措施表明，虽然参与者喜欢更简单的格式，没有任何改变提高可行性。参与者的评级容易出现逻辑上的不一致，参与者发现TTO的所有4个版本都令人困惑，并且不适合精神分裂症治疗的背景。
Measuring preferences for schizophrenia outcomes facilitates meaningful integration of multiple outcome measures and multiple perspectives on treatment outcomes. The Time Tradeoff (TTO) technique, specifically developed for measuring health state preferences, is used widely in health research, but some evidence suggests that the TTO may work less well with schizophrenia than with other health conditions. This study tested the hypotheses that tailoring the time frame of the standard TTO to the course of schizophrenia and simplifying its presentation fromat would improve its feasibility and efficiency. Forty clinicians provided TTO ratings using 1 of 4 combinations of time frame and presentation format. Numeric ratings and quantitative and qualitative measures of feasibility showed that while participants preferred the simpler format, none of the alterations improved feasibility. Participants' ratings were prone to logical inconsistencies and participants found all 4 versions of the TTO confusing and poorly suited to the context of schizophrenia treatment.
