Development and Initial Validation of the NephRN Perceptions Toward Advance Care Planning Instrument.

The purpose of this study was to develop and pilot test an instrument to measure the perceptions of nephrology nurses toward advance care planning, the NephRN Perceptions Toward Advance Care Planning instrument. Four components of advance care planning were identified: knowledge, attitudes, comfort, and support. The four-component solution explained 63.88% of variance. Cronbach's alpha was 0.92, and subscale reliability ranged between 0.86 and 0.94. This instrument shows promise as a reliable and valid measure of nephrology nurse perceptions toward advance care planning for persons with chronic kidney disease.
