Recently, a longitudinal project on the development of children with a serious cognitive and motor developmental delay has started in Belgium and the Netherlands. The aims of this study are to evaluate the cognitive, motor, communicative and social-emotional abilities of young children with a severe cognitive and motor developmental delay (between 6 months and 4 years old at the first administration moment); to analyze the developmental trajectories and patterns in these children; to evaluate the effect of family and broader contextual variables on the developmental trajectories; and to identify subgroups of children with different developmental patterns or trajectories. Six-monthly assessments of the child’s cognitive, motor, communicative and social-emotional abilities and of contextual variables are realized by means of standardized observations and questionnaires. Preliminary results for motor, communicative and social-emotional abilities will be presented. Methods and results will be discussed with the participants of the workshop.

Motor abilities are measured by means of the Portage Program Netherlands- Revised - PIMD questionnaire of motor development (PPN-R-PIMD). Questionnaires of 18 participants were completed by parents. Initial analyses suggest atypical trajectories of motor development for children with PIMD. Global comparison of subgroups of children with similar additional problems suggest specific patterns related to comorbidity.

The Early Social Communication Scales (ESCS) is used for the measurement of communicative abilities. The ESCS is a standardized instrument which measures non-verbal communicative abilities. The target behaviours are: (1) joint attention behaviours, (2) behavioural requesting behaviours, and (3) social interaction behaviours. The first explorative results of 14 participants show that these children are able to show joint attention and behavioural requesting behaviours, although with a large variability.

Social-emotional abilities are assessed through the Scale for Emotional Development (SEO-R²). The SEO-R² is a structured interview with primary caregivers on the social-emotional development of the child. This interview results in a developmental profile of the child, incorporating thirteen domains (e.g. emotion regulation, relation to adults,…). The results of a subgroup of 18 participants show these children are functioning within the adaptation or first socialization phase of socio-emotional development.
