The authors reviewed 21 studies assessing housing preferences of mental health consumers to examine current methods of assessment, to obtain information on the reliability and validity of the assessment instruments used, and to determine whether a better approach to assessing preferences might be found. The review found little data on the reliability or validity of the assessment instruments and revealed heavy reliance on the use of fixed-choice questions that limit consumer expression of preferences. Responses to such questions can be misleading because they may or may not reflect real-life constraints, such as preferring a roommate only because living alone is not affordable. However, the authors believe the factorial survey model, which uses vignettes to present different combinations and characteristics of living arrangements, may allow investigators to better understand consumers' true preferences. They propose creating and pilot testing an instrument using such vignettes.
作者回顾了21项评估心理健康消费者住房偏好的研究，以审视当前的评估方法，获取所用评估工具的信度和效度信息，并确定是否能找到更好的偏好评估方法。该综述发现，关于评估工具信度或效度的数据很少，且显示出严重依赖使用固定选择问题，这限制了消费者对偏好的表达。对这类问题的回答可能会产生误导，因为它们可能反映也可能不反映现实生活中的限制因素，比如仅因独自生活费用过高而选择室友。然而，作者认为，使用 vignettes 来呈现不同居住安排组合和特征的因子调查模型，可能会让研究者更好地理解消费者的真实偏好。他们提议创建并试点测试一种使用此类 vignettes 的工具。
