GOAL: Gait Outcome Assessment List

Background/Purpose: Ambulatory children with cerebral palsy (CP) undergo different interventions to enhance physiological functions, improve their gait, and in the end help them better participate in activities of daily life. To understand the needs and individual goals of these patients and their parents a new instrument, the GOAL, was introduced by Narayanan and Coworkers. The reliability of the German version (GV) of GOAL was to be assessed.

Methods: The original questionnaire was translated following the guidelines of transcultural adaption of health-related quality of life measurements. After finalizing the German version, 91 patients (classified by the Gross Motor Function Classification System (GMFCS); 32 level I, 27 level II, and 32 level III) and/or their parents were asked to complete the questionnaire consisting of 48 items across 6 domains.

Results: The mean total score was 57.3 (SD 16.1). The test-retest reliability proved to be acceptable. As proposed, the GOAL score decreased the higher the patient’s GMFCS level. Age (subgroups older and younger than 10 years) does not seem to have a major effect on the total scoring. Also a bilateral versus a unilateral CP did not seem to affect the score significantly. Children seem to better judge themselves than parents do (mean parents: 74.27, mean child: 82.18; p-value = 0.0002).

Conclusion: The GOAL questionnaire GV has sufficient reliability as a proxy and patient reported outcome measurement of health status and well-being of ambulatory children with CP.
