The Millennium Cohort Study (MCS) assessed their cohort members (CMs) during the study’s sweep at 9 months age using the Developmental Milestones measures.
Details on these measures and the data collected from the CMs are outlined in the table below.
|Domain:||Fine and gross motor coordination|
|Receptive and productive vocabulary|
|Measures:||Developmental milestones using questions from two developmental questionnaires:|
|8 questions from Denver Developmental Screening Test (DDST) which screens for potential developmental problems|
|5 items were chosen from a UK adaptation of MacArthur Communicative Development Inventories (CDI) identifies early communicative gestures|
|Administrative method:||Parent report; face to face interview|
|Procedure:||Parents were asked to respond to selected statements from the tests, using a three point scale Often/once or twice/not yet for the Denver Developmental Screening Test, and Often/sometimes/not yet for the MacArthur CDI.|
