通过测量偏好来量化治疗结果的重要性，可以构建反映多种结果的相对重要性、结果之间的权衡以及不同利益相关者的观点的总体结果指标。然而，标准偏好评估方法在认知上很复杂，对于精神分裂症和其他严重精神疾病患者来说可能尤其具有挑战性。如果利益相关者群体不以类似的方式使用这些方法，则偏好可能没有意义或没有可比性。本研究结合了定性和定量方法，比较了 2 个利益相关者群体（精神分裂症治疗的消费者和临床医生）对三种标准偏好评估方法（评分量表、时间权衡和配对比较）的理解和决策策略。结果表明，评级量表方法可能会产生最有效和最具可比性的偏好值，因为它被消费者和临床医生很好地理解和接受。两组都发现时间权衡方法难以使用，并且不太适合评估精神分裂症的结果。
Quantifying the importance of treatment outcomes by measuring preferences allows construction of aggregate outcome indicators that reflect the relative importance of multiple outcomes, trade-offs between outcomes, and the perspectives of different stakeholders. However, standard preference assessment methods are cognitively complex and may be particularly challenging for persons with schizophrenia and other serious mental illnesses. Preferences may not be meaningful or comparable across stakeholder groups if the groups do not use the methods in similar ways. This study combined qualiative and quantitative methods to compare comprehension and decision strategies across three standard preference assessment methods (Rating Scale, Time Tradeoff, and Paired Comparison) in 2 stakeholder groups (consumers of schizophrenia treatment and clinicians). Results indicate that the Rating Scale method is likely to yield the most valid and comparable preference values because it is well understood and acceptable to both consumers and clinicians. Both groups found the Time Tradeoff method difficult to use and poorly suited to evaluating schizophrenia outcomes.
