SDQ for 2-4 year olds: Normative data from Britain

Sources of Parent SDQ data for children aged 2-3 years

• Dumfries, Scotland (N=1353): Parents in Dumfries in Scotland routinely complete SDQs when their children start Nursery, which is generally the start of the term after their 3rd birthday. There are 3 intakes per year and percent completion is in the high 90s. We are grateful to Amelia Hamilton, Anne-Marie Humes, Anne Macfarlane and colleagues from Dumfries and Galloway for providing anonymized data on 1,353 children.
  
  
• Glasgow, Scotland, sample A (N=292): In August 2011, all families in four regions of Greater Glasgow with children aged 30 months were offered a home visit by their health visitor/public health nurse, and this visit included completing an SDQ (Sim et al. BMC Pediatrics 2013, 13:206). We are grateful to Lucy Thompson, Else Ekevall, Kim Jones, Fiona Sim, and Philip Wilson and colleagues from Glasgow for providing frequency distributions for the various SDQ scores for SDQs completed by parents (54% of those eligible for a home visit).
  
  
• Glasgow and Clyde area, Scotland, sample B (N=9947). Since 1st July 2013, all children aged 30 months of age residing in NHS Greater Glasgow and Clyde (NHSGGC) should receive a comprehensive health assessment from their health visitor/public health nurse. As part of this assessment, NHSGGC has adopted the parental completion of the SDQ to aid detection of possible behavioural problems. The introduction of the universal 30 month assessment in NHSGGC follows the piloting of a similar assessment in the board area during August 2011 (captured in our sample A, described above). Approximately 85% of eligible children have received an assessment to date (NHS GGC Information Services: unpublished). We are grateful to NHS Greater Glasgow and Clyde Information Services for providing anonymised SDQ data for 9947 children.

Sources of Teacher SDQ data for children aged 4 years

• Glasgow, Scotland (N=10,004): SDQs are routinely completed by preschool staff in Local Authority and Partnership nurseries in Glasgow City; these are nurseries where places are paid for by the Local Authority. The teacher SDQ for 2-4 year olds was used to collect data in the spring terms of 2012, 2013 and 2014, for children aged 4 years old. We are grateful to Louise Marryat and Michele McClung for providing frequency distributions for the various SDQ scores, and to the Glasgow City Council Education Services and the Scottish Government for having funded the collection of these SDQs in nurseries.
