Aim To describe behavioural and emotional symptoms among Icelandic preschool children with cerebral palsy (CP). Method Children with congenital CP, assessed with the Child Behavior Checklist/1(1/2)-5 (CBCL/1(1/2)-5) and Caregiver-Teacher Report Form (C-TRF), were enrolled in the study. A comparison group was recruited from the general population. Thirty-six children (53% males) with CP were assessed at a mean age of 4 years 11 months (SD 5mo, range 4-6y); 26 (72%) had bilateral distribution of symptoms and 32 (89%) had spastic CP. Thirty (83%) were at Gross Motor Function Classification System levels I or II and six at levels III or IV. For comparison, 110 (43% males) and 120 (48% males) children were assessed with the CBCL/1(1/2)-5 and the C-TRF respectively, at a mean age of 4 years 6 months (SD 6mo, range 4-6y). Results Sixteen children (48%) with CP had high scores on total problems scale of the CBCL/1(1/2)-5 and 20 (65%) on the C-TRF compared with 18% of the comparison group, both on the CBCL/1(1/2)-5 and the C-TRF (p
