Preliminary Validation of a Measure of Life Support Preferences

A rapid, easy to use instrument that provides illustrations of life support choices can enhance discussion of life support measures with patients. The goal of this preliminary study was to develop and validate an instrument, the Life Support Preferences Questionnaire (LSPQ). In a convenience sample of 116 healthy adults, the LSPQ showed a sturdy degree of internal consistency for a short measure. The 2‐week stability evidence was supportive of respondents' consistent attitudes over time at both the item and scale level. Principal factor analyses give evidence there is one dominant theme underlying the items. Use of the LSPQ with hospitalized patients is being explored as a response to policy changes resulting from the 1991 Patient Self‐Determination Act
