Psychometric properties of the Danish version of the resilience scale for adults in individuals with acquired brain or spinal cord injury, and their family members

OBJECTIVE: To investigate validity and reliability of the Danish version of the Resilience Scale for Adults among individuals with acquired brain or spinal cord injury, and their family members.

DESIGN: Cross-sectional study.

SUBJECTS/PATIENTS: Adults with acquired brain or spinal cord injury, and their family members.

METHODS: Unidimensionality, floor/ceiling effects, and internal consistency of the 6 subscales were analysed using confirmatory factor analysis. A series of models were estimated to investigate structural validity, and construct validity was analysed using correlations.

RESULTS: Family cohesion, Planned future, and Perception of self showed good reliability (ω = 0.79-0.83) and good model fit (Comparative fit index: 0.986-1.000). Social resources and Social competence demonstrated adequate reliability (ω = 0.81 and 0.75) and good fit, accounting for local dependency. Structured style had poor reliability (ω = 0.53) and model misfit. The Resilience Scale for Adults was best represented by a 6-factor correlated model, compared with a single first- or second-order factor, but all models showed inadequate fit. All scale scores correlated negatively with scores of anxiety and depression.

CONCLUSION: All but 1 subscale demonstrated good psychometric properties. The Resilience Scale for Adults can be used to measure different aspects related to resilience for this mixed population.
