Examining Generalizability of Older Adults' Preferences for Discussing Cessation of Screening Colonoscopies in Older Adults with Low Health Literacy.
Ontology highlight
ABSTRACT: BACKGROUND/OBJECTIVES:Many older adults receive unnecessary screening colonoscopies. We previously conducted a survey using a national online panel to assess older adults' preferences for how clinicians can discuss stopping screening colonoscopies. We sought to assess the generalizability of those results by comparing them to a sample of older adults with low health literacy. DESIGN:Cross-sectional survey. SETTING:Baltimore metropolitan area (low health literacy sample) and a national, probability-based online panel-KnowledgePanel (national sample). PARTICIPANTS:Adults 65+ with low health literacy measured using a single-question screen (low health literacy sample, n?=?113) and KnowledgePanel members 65+ who completed survey about colorectal cancer screening (national sample, n?=?441). MEASUREMENTS:The same survey was administered to both groups. Using the best-worst scaling method, we assessed relative preferences for 13 different ways to explain stopping screening colonoscopies. We used conditional logistic regression to quantify the relative preference for each explanation, where a higher preference weight indicates stronger preference. We analyzed each sample separately, then compared the two samples using Spearman's correlation coefficient, the likelihood ratio test to assess for overall differences between the two sets of preference weights, and the Wald test to assess differences in preference weights for each individual phrases. RESULTS:The responses from the two samples were highly correlated (Spearman's coefficient 0.92, p?
