Developmental domain | Developmental quotient (percentile) | ||||
---|---|---|---|---|---|
4 ½ months corrected age | 8 ½ months corrected age | 21 months chronological age | 29 months chronological age | 44 months chronological age | |
Locomotor | 66 | 88.5 (21) | 87 (21) | 76 (7) | Could not be assessed |
Personal and social | 66 | 102 (49) | 100 (49) | 84 (16) | Could not be assessed |
Hearing and Language | 88.8 | 100 (11) | 80 (11) | 60 (1) | 56 (<first percentile) |
Eye and hand coordination | 50 | 94 (22) | 88 (22) | 77 (7) | Could not be assessed |
Performance/Foundations of learning | 50 | 85.7 (18) | 86 (18) | 87 (20th percentile) |
Notes: The Griffiths Mental Development Scales version III was used for the developmental evaluation. This contains five separate scales: loco motor, personal‐social, hearing and speech, eye and hand coordination, and foundations of learning/performance. The total developmental quotient (DQ) and sub‐quotients were calculated as outlined in the manual. The mean DQ is 100 and a SD of 13 for the whole population as per the test manual for each domain (Griffiths R. The abilities of young children. High Wycombe, UK: The Test Agency, 1976.). Thus, DQ score of less than 80 with a percentile score of <5 was considered as abnormal.
