Abstract
Delayed advance planning and costs of life sustaining treatments at end of life significantly contribute to the economic burden of healthcare. Clinician barriers include perceptions of inappropriate timing, lack of skills in end-of-life communication and viewing readiness as a behavior rather than a death attitude. This study developed and validated a measurement of psychological preparedness for advance directive completion. Confirmatory factor analysis ( N = 543) of a 35 item pool (Cronbach α = .96) supported five sub-scales; psychological comfort (α = .87), desire to know (α = .88), thinking (α = .84), willingness (α = .82) and existential reflection (α = .79) with a possible common factor (α = .84). Results suggested significant predictors of completing directives in 30 days included discussion (OR .08, p < .001), preparedness (OR 4.08, p = .03) and uncertainty (OR 4.37, p = .02). APP = 35 is a reliable and valid measure with utility to assess readiness for completion of EOL documents.
