To translate the ACTIVLIM-CP questionnaire, developed to assess global activity performance in children with Cerebral Palsy (CP), into Turkish and to investigate its psychometric properties. Eighty-nine children with CP, aged between 2 and 18 years (mean age: 10.08 ± 4.94 years), were included in the study. Internal consistency was measured by Cronbach's alpha and test-retest reliability was assessed using intraclass correlation coefficient (ICC). Convergent validity was evaluated through the pattern of correlations between the ACTIVLIM-CP with PEDI, ABILOCO-Kids, ABILHAND-Kids, and Wee-FIM scores. Known-group comparisons were made according to epilepsy existence and ambulation level measured by Gross Motor Function Classification System (GMFCS). Internal consistency was excellent (Cronbach's α = 0.990), and the ICC for the test-retest reliability was 0.990. There was a very strong correlation between ACTIVLIM-CP and ABILHAND-Kids (r = 0.946), WeeFIM (r = 0.900), PEDI Functional Skills and Caregiver Assistance scores (r = 0.954, r = 0.937, respectively), and ABILOCO-Kids (r = 0.817) (p
