Preference measurement using conjoint methods: an empirical investigation of reliability
实证研究了离散选择联合测量方法在医疗保健中的重测信度，以膝关节损伤诊疗为背景，证明该方法在输入数据和结果层面均具有高可靠性。
The application of conjoint measurement to the field of health economics is relatively new, although there is growing interest and there have been a number of studies undertaken recently. Wider acceptance of the technique requires methodological issues concerning both reliability and validity to be addressed. This paper reports an empirical investigation of the test-retest reliability of the discrete choice conjoint measurement approach in health care. This investigation of conjoint reliability was framed using the clinical context of investigation and treatment of knee injuries. A high level of reliability at both the input data and results levels was demonstrated.
