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.
One hundred children and adolescents (aged 2–19 years) with acquired or traumatic brain injury were included.
The CALS was administered at inpatient rehabilitation admission and discharge.
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.
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.
