Design Features of MCS
Cohort born over 12 month period Season of birth effects Spread workload of professional interviewers Sampling necessitated
Geographically clustered by electoral ward Wards being disproportionately stratified Better approach to issue of community & local services
Content multi-purpose & multidisciplinary but with greater emphasis on social rather than medical

Father’s Involvement in Scotland
88% of Fathers in Scotland (85% UK) look after the cohort child at least weekly and 66% of Fathers in Scotland (57% UK) change a nappy at least once a day.
Longitudinal Evidence A strong father figure is associated with academic
success (Flouri et al 2003) Girls whose fathers are involved in their upbringing are
less likely to have mental health problems in later life (Flouri and Buchanan 2002)

MCS: The Future of Data collection
Future surveys are planned for: Age 5 2005-6 Age 7 2007-8
etc…….
Possible future design elements Obtain info on or from daycare provider at 3 At 5 and 7 Repeat interviews with resident parents Repeat cognitive and behavioural assessments with children Collect information from Schools? Collect information on child’s hospital episodes?
