Validity and reliability of the left ventricular assist device self-care behaviour scale.

ABSTRACT:

Background

Adequate self-care behaviour is essential for patients with a left ventricular assist device (LVAD) to prevent complications, prolong life, and optimise quality of life. However, there were no valid and reliable measurements available to assess self-care behaviour among patients with LVAD. We have previously developed the 33-item LVAD self-care behaviour scale.

Objectives

To evaluate psychometric properties of the 33-item LVAD self-care behaviour scale.

Methods and results

Data on 127 patients with a LVAD in Israel, Japan, and the USA were analysed (mean age 51±14.3, 81% male). Exploratory factor analysis extracted three factors, and 13 items were excluded from the scale. Internal consistency assessed by Cronbach's alpha was acceptable for the total scale (
