Psychometric assessment of the consideRATE questions, a new measure of serious illness experience, with an online simulation study.

ABSTRACT:

Objective

To assess the psychometric properties of the consideRATE questions, a measure of serious illness experience.

Methods

We recruited people at least 50 years old via paid panels online, with US-Census-based quotas. We randomized participants to a patient experience story at two time points. Participants completed a series of measures, including the consideRATE questions. We assessed convergent (Pearson's correlation), discriminative (one-way ANOVA with Tukey's test for multiple comparisons) and divergent (Pearson's correlation) validity. We also assessed intra-rater reliability (intra-class correlation) and responsiveness to change (t-tests).

Results

We included 809 individuals in our analysis. We established convergent validity (r = 0.77; p < 0.001); discrimin
