Introduction and Purpose:The Life Participation for Parents is an assessment tool designed to measure a parent's ability to participate in daily life while raising a child with special needs. Previous studies have established the effectiveness of the instrument in providing valuable information for designing family-centered goals and intervention. Further investigation is needed to determine if the instrument is sensitive enough to measure change after intervention. This study is designed to further develop the LPP as an assessment for providing family-centered intervention for children with special needs and their families and to investigate child characteristics leading to issues in parental participation.
