使用教学先进指令的使用假定，随着时间的推移和生活状况的变化，对维持生命的医疗治疗的偏好保持稳定。在9种疾病情况下，有332名老年人的样本记录了他们对4种维持生命治疗的偏好。这些偏好再次引起了我和原始采访后的两年。总体而言，随着时间的推移，对生命治疗的偏好均等稳定，但稳定性在判断之间差异很大。对于最严重和最严重的疾病情况，拒绝治疗的偏好最为稳定。年龄，性别，教育以及提前指令的事先完成都与偏好稳定性有关，证据表明，身体或心理功能的下降导致对生命的治疗的兴趣下降。
The use of instructional advance directives assumes that preferences for life-sustaining medical treatment remain stable over time and across changes in life condition. A sample of 332 older adults recorded their preferences for 4 life-sustaining treatments in 9 illness scenarios. These preferences were elicited again I and 2 years after the original interview. Overall, preferences for life-sustaining treatment were moderately stable over time, but stability varied significantly across judgments. Preferences were most stable for illness scenarios that were most and least serious and for decisions to refuse treatment. Age, gender, education, and prior completion of an advance directive were all related to preference stability, and evidence indicated that declines in physical or psychological functioning resulted in decreased interest in life-sustaining treatment.
