Objective A preliminary investigation of the psychometric properties of the Cognitive and Linguistic Scale (CALS), a measure of cognitive and linguistic recovery following brain injury in children and adolescents.

Participants One hundred children and adolescents (aged 2–19 years) with acquired or traumatic brain injury were included.

Methods The CALS was administered at inpatient rehabilitation admission and discharge.

Results Internal consistency and interrater reliability were high. Factor analysis revealed 2 factors (basic responding, higher-level cognitive skills). Correlations with the Functional Independence Measure for Children (WeeFIM) ranged from 0.51 to 0.89; highest correlation was between WeeFIM cognitive domain and CALS total score. CALS scores improved significantly between admission and discharge.

Conclusion On the basis of these preliminary analyses, the CALS is a promising measure to track cognitive and linguistic recovery in children and adolescents with brain injury during inpatient rehabilitation.
