| Abstract |
|
From April to September 1992, 40 infants with age 6 months to 8 months who had been born in Yongdong Severanve Hospital were studied for evaluation of their development using Bayley developmental test. The result obtained were as follow:
1) Mean mental developmental index(MDI) is higher than mean psychomotor developmental index (PDI) and the values are 101.9¡¾8.2 and 105.5¡¾9.8 respectively.
2) As age increases, both raw scores are increased but mean standard scores are decreased and there is statistical significance in PDI.
3) The correlation coefficient of age and psychomotor scale is 0.77 and that of age and mental scale is 0.83.
4) Mean correlation coefficient between PDI and MDI is 0.44 and correlation coefficient in 6 months is 0.54 and it decreased to 0.31 in 7,8 months.
5) Among the physical measurement indices, there is high correlation between height and weight but not with head circumference.
6) There is no statistical significance between each developmetal scale with mode of delivery and mother' working status. |
