The purpose of this study was to develop and evaluate a brief, self-re
port measure of the degree of perceived change resulting from cardiac
illness. Life change has been widely recognized as stressful, but it i
s usually assessed with generic checklists of events which have been f
ound wanting in terms of reliability and validity. The proposed measur
e was designed to assess life change in factors commonly reported to b
e important in recovery from cardiac illness. The Cardiac Change Scale
was found to have very good internal consistency and acceptable test-
retest reliability. The construct and criterion validity of the Cardia
c Change Scale were supported.
