Data Collection Event

8.5 year Follow Up

At 8 years of age, participants underwent a clinical assessment to assess cerebral palsy, visual and hearing impairment.

Parents of the participant were interviewed about socioeconomic status (SES), living conditions, and cognitively stimulating parenting. A semi-structured friendship and family interview was used to assess the participant's friendships, and the Mannheim Parent Interview to obtain DSM IV diagnoses and information about bullying.

The participant completed the Harter Scales Self-Perception Profile for Children. Kaufman Assessment Battery for Children (KABC) was used to assess cognitive function and the participant also completed language, reading, spelling and maths tests. School success was determined from school reports and parent interview.

Mother-child interactions were also rated by a psychologist using a standardised coding system, the Assessment of Mother‐Child‐Interaction with the Etch‐a‐Sketch (AMCIES). Child behavior was evaluated by a psychologist during a cognitive assessment using the Tester's Rating of Child Behavior (TCRB), and a consensus model of attention evaluated by entire research team (TEAM rating of child behavior). Parents also completed the Child Behavior Checklist (CBCL) and Emotionality Activity and Sociability (EAS) Temperament Survey questionnaires.
