Rasch Properties of the Cognitive and Linguistic Scale and Optimization for Outcome Trajectory Modeling in Pediatric Acquired Brain Injury.

ABSTRACT:

Objectives

To (1) determine if items on the Cognitive and Linguistic Scale (CALS) follow a Rasch distribution and (2) explore the relationship between Rasch-derived Cognitive Ability Estimates and outcome trajectory parameters using a nonlinear mixed-effects modeling approach.

Design

Retrospective study.

Setting

Pediatric inpatient rehabilitation hospital.

Participants

A total of 252 children (N=252) aged of 2-21 years (median, 11.8 [IQR, 6.4-15.9] years) consecutively admitted to an inpatient rehabilitation brain injury unit (2008-2014) for a first inpatient admission after acquired brain injury.

Interventions

Not applicable.

Main outcome measures

Rasch-derived Cognitive Ability Estimates from the CALS and associated outcome trajectory parameters
