Test-Retest Reliability of the Dispositional Resilience Scale-15, a Brief Hardiness Scale

Abstract

Test-retest correlations provide the most appropriate estimate of reliability when short scales are used to measure complex constructs. A brief, 15-item hardiness scale was developed from a longer version known as the Dispositional Resilience Scale (DRS), which first appeared in 1989. This short hardiness scale (DRS–15) has the advantages of brevity, good internal consistency, and validity (Barone, 1995, 1999); however, test-retest reliability has not yet been estimated. The present study addresses this issue, using a sample of 104 military academy cadets. The 3-wk. test-retest reliability coefficient was .78.
