Comparison among Different Versions of Connor-Davidson Resilience Scale (CD-RISC) in Rehabilitation Patients after Unintentional Injury

Objective: The current study was to compare the psychometric properties of the 25-item version (CD-RISC25), 10-item Connor-Davidson version (CD-RISC10) and 2-item Connor-Davidson version (CD-RISC2) in rehabilitation patients after injury. Method: A sample of 115 Chinese patients was measured by CD-RISC25, CD-RISC10 and CD-RISC2, PTSD Checklist-Civilian Version (PCL-C) and Symptom Checklist-90-Revised (SCL-90-R) during the rehabilitation period. Result: (1) Cronbach’s alpha values indicated sufficient and high reliability to provide confidence in interpreting the score for the three versions; (2) The resilience measured by CD-RISC25 and CD-RISC10 both correlated negatively and significantly with PTSD and mental health problems, while this was not observed when resilience was measured by CD-RISC2; (3) Through ROC curves analyses, the CD-RISC25 and CD-RISC10 had similar discrimination for positive/negative group of SCL-90 and PTSD/non-PTSD. Conclusion: The results supported the application of CD-RISC10 in clinical researches due to its excellent psychometric properties and time efficiency.
