Cerebral palsy (CP) is a chronic condition that causes the most childhood disabilities on worldwide. Impairment in movement and posture development seen in children with CP it causes difficulties in performing activities and affect in emotional, social, and cognitive abilities cause limited participation in everyday life. The ICF-CY child is divided into five categories: body structure and functions, activities, participation, environmental and personal factors, it is treated holistically. Initially, children with CP have adopted the view that environmental factors can also affect functionality, while focusing on the treatment of motor disorders to reduce activity and participation limitations in physiotherapy and rehabilitation applications. Environmental factors; the environment in which the child lives, his family, the devices he uses, health and care services, and government policies. These factors vary according to each country's own cultural and economic opportunities. The investigator planned to do this study because we found that there is a need for a comprehensive study of children with SP in Turkey, which does not reveal the relationship between environmental factors and activity and level of participation.

The study consist of two phases:

1. European Child Environment Questionnaire (ECEQ) will translate in to Turkish in the first phase.

   • Forvard translation (translate to Turkish from English)
   • Expert opinion (Turkish version will control by expert)
   • Back translation (Turkish version will translate to English)
   • Cultural adaptation Validity and reliability study will done

2. The relationship between environmental factors and activity and participation will be investigated in the second phase.
