Shared decision making is the process of interacting with patients in arriving at informed values-based choices when options have features that patients value differently. Patient decision aids (PtDAs) are evidence-based tools designed to facilitate that process. Numerous randomized trials indicate that PtDAs improve decision quality and prevent overuse of(More)
The purpose of this study was to examine attitudes toward the duration of survival in different health states. Health professionals were asked to consider hypothetical situations in which a specified period of time would be spent in a defined health state. Preferences for these different situations were assessed using two methods--a Preference Questionnaire(More)
The standard gamble, derived from decision theory, is considered a criterion method for obtaining patients' values for different health states. In this method, a rater's value for a health state is obtained by determining, in a hypothetical setting, his readiness to remain in that state or take a risky choice with different outcomes of known value.(More)
The purpose of this study was to describe the life-sustaining treatment preferences of dialysis patients and to compare the acceptability of two generic and a disease-specific advance directive (AD). Of 532 potentially eligible hemodialysis patients, 95 (17.9%) participated in the study. These patients completed two generic (the Centre for Bioethics Living(More)
In health status index construction quantitative values for different states of health are frequently obtained by presenting written descriptions to raters whose values are elicited using one or more methods. In this study the authors examined the influence of several aspects of this measurement process upon the quantitative results obtained. They prepared(More)
Despite increasing emphasis on advance directives, there has been little methodologic work to assess preferences about the "do not resuscitate" (DNR) order. This developmental work assessed, in a non-patient group, the performance of a probability-trade-off task designed to assess DNR attitudes, in terms of framing effects and stability of preferences. 105(More)
PURPOSE To elicit neck pain (NP) patients' preference scores for their current health, and investigate the association between their scores and NP disability. METHODS Rating scale scores (RSs) and standard gamble scores (SGs) for current health were elicited from chronic NP patients (n=104) and patients with NP following a motor vehicle accident (n=116).(More)
BACKGROUND Posttraumatic Stress Disorder (PTSD) is a commonly occurring mental illness. There are multiple treatments for PTSD that have similar effectiveness, but these treatments differ substantially in other ways. It is desirable to have well-informed patients involved in treatment choices. A patient decision aid (PtDA) is one method to achieve this(More)
BACKGROUND Over 100 trials show that patient decision aids effectively improve patients' information comprehension and values-based decision making. However, gaps remain in our understanding of several fundamental and applied questions, particularly related to the design of interactive, personalized decision aids. This paper describes an interdisciplinary(More)
One aspect of O'Connor's Decisional Conflict Scale [O'Connor, A.M., Validation of a decisional conflict scale, Med. Decis. Making 15 (1995) 25-30] is the assessment of selected factors (perceived lack of information, undue social pressure, lack of support from others, and lack of clarity about personal values) that are believed to contribute to decisional(More)
