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.

Individuals with acquired brain injury, individuals with spinal cord injury, and family members were analysed together to get enough data for factor analysis, so the study cannot show whether the scale works differently in each group. The analysed sample was 140 participants, and the authors say the small sample size may increase uncertainty in model-fit estimates and reduce statistical power. The study used baseline data only, so it cannot show whether the scale gives stable results over time. The adjusted models for Social resources and Social competence may not generalise beyond this sample. The data are not openly accessible because of Danish health information rules, so outside researchers cannot check the analyses.

The authors declared no conflicts of interest. The research was funded by an unrestricted grant from the Council of Danish Victims Fund and Oestifterne.

Do not treat the RSA total score as one validated resilience measure. The authors found evidence against a single overarching factor, and the Structured style subscale had inadequate fit and poor reliability.
