Validation of the Dysgraphia Disability Scale (DDS); An assessment tool for writing difficulty

Abstract

Dysgraphia is defined as the difficulty in the production of written language. This study was carried out on 50 subjects aged 6-12 years who suffered from writing disabilities. This methodological study was designed to measure the possible breakdown mechanisms causing dysgraphia. A scale was created to cover most of the weak points in dysgraphia especially the fine motor and proprioceptive aspects. Reliability and validity of this scale were performed to allow its application. Findings were dealt with statistically and it was found that three types of dysgraphia have been known as Dyslexic, Motoric, and Spatial Dysgraphia. The scale diagnoses dysgraphia in an objective way and the severity of the condition can be determined in addition. This helps better understand the patients’ needs when a trainer designs the remediation program.
