Psychometric properties of Connor-Davidson Resilience Scale in a sample of military active duty service members

Resilience is a dynamic process in which the individual displays positive adaptive skills despite experiencing signifi cant traumatic adversity; it is a measure of the ability to cope with stress. Connor-Davidson Resilience Scale (CD-RISC) is  a measurement of resilience, which is composed of 25 items rated on a 5-point scale (0-4), with higher scores reflecting greater resilience.  This study analyzes the psychometric properties of the Connor and Davidson Resilience Scale (CD-RISC) in a sample of active duty service members in treatment for Post-Traumatic Stress Disorder

Method: A survey research method was used. The participants were active duty service members in treatment for Post-Traumatic Stress Disorder. Interviewers surveyed a total of 539 active duty service members. The CD-RISC was used as data collection instrument. We used latent class analysis, principal component analysis factor and confi rmatory factor analysis to determine the factor structure of the CD-RISC.

Results: Latent class analysis showed that three subgroups (latent classes) can be distinguished. Principal component analysis factor yielded a 5-factor structure of resilience, Confirmatory factor analysis verified the original five-factor structure of the CDRISC.

Conclusions: The CD-RISC has been shown to be a reliable and valid tool for measuring active duty service members’ resilience.
