Life experiences and psychosocial development of the child: the role and quality of child care services

The main objective of the EMIGARDE study is to characterize the role of early life experiences in the success of children. More specifically, it sought to determine the associations between child care quality (when children are between 2 and 4 years) and children’s pre academic skills at 4 years. To do so, specific aims of the EMIGARDE study are:

To examine the extent to which patterns of change in child care quality over time predicted the child cognitive performance;
To examine whether or not distinct dimensions of quality were particularly relevant to cognitive performance.

General Information on Follow Up (profile, frequency)

Prior to the children’s second birthday, families were invited to participate in the EMIGARDE study. Participants were followed-up when children were 3, 4, 5-6, 7-8, 12-14 and 13-15 years old. Child care services regularly attended by the children also received a visit when the child was 2, 3, and 4 years old.

Timeline

Information was collected on birth weight of the child, prematurity of the child and maternal smoking during pregnancy.

Start Date

2003 (June)

End Date

2004 (April)

Data sources

Questionnaires
Physical measures

When the children were 2 years old, parental interviews (mostly with mothers) were conducted and child care quality assessments were done.

Parental interviews provided information regarding the family characteristics (socio-demographics of both parents, maternal depression) and the child characteristics. Lifetime maternal depression was assessed with a modified life-time depression section of the Diagnostic Interview Schedule.

Participating child care services (attended regularly by children) received a visit. Center-based child care quality was assessed with the ECERS–R for children 2½–4 years and with the ITERS–R for children under 2½ years. Family-based child care quality was assessed with the FDCRS.

When the children were 4 years old, parental interviews (mostly with mothers) were conducted and child care quality assessments were done.

Moreover, a home visit was conducted, including cognitive tasks to assess school readiness, receptive vocabulary, and numeracy-related abilities. The Number Knowledge Task (NKT), The Peabody Picture Vocabulary Test–Revised (PPVT–R) and The Lollipop Test were used.

Cognitive measures

When the children were 7-8 years old, parental interviews (mostly with mothers) were conducted.

Information was collected on early life experiences, childcare over the preschool years and children’s emotional development. This data collection included detailed measures of emotional development of children such as through self-reported emotions and behaviours (using the Berkeley Puppet Interview) as well as teacher and parent reports, in addition to various tasks of emotion-processing (facial expression recognition).

The main objective of these two new data collections is to study children's social, emotional and socio-cognitive functioning in the early adolescent years with a special focus on adolescents' social media use and how this relates to social, emotional and socio-cognitive functioning.

Several online questionnaires collected information pertaining to social media use, emotional and behavioural difficulties, personality, and friendships. Additionally, tasks of emotion-processing (facial expression recognition) as well as socio-moral reasoning are included.
