Primary | Changes in Maternal Serum B12 Concentration From 1st to 3rd Trimester | from 1st to 3rd trimester | ||
Secondary | Cognitive Scale, Bayley Scales of Infant Development, 3rd Edition | The cognitive scale is a single scale that measures sensorimotor integration, concept formation, attention, habituation, and memory. Higher values represent better performance. The interquartile range provides an adequate assessment of the variability of the data. The minimum possible score of the cognitive scale is 0 and the maximum possible score is 91. | 9 months | |
Secondary | Receptive Language Scale, Bayley Scales of Infant Development, 3rd Edition | The Receptive Language Scale is a single scale that measures the ability of the child to recognize sounds and understand spoken words and directions. Higher values represent better performance. The interquartile range provides adequate assessment of the variability of the data. The minimum possible score is 0 and the maximum possible score is 49. | 9 months | |
Secondary | Expressive Language Scale, Bayley Scales of Infant Development, 3rd Edition | The Expressive Language Scale is a single scale that measures the ability of the child to communicate using sounds, gestures, or words. Higher scores represent better performance. The interquartile range provides adequate assessment of the variability of the data. The minimum possible value is 0 and the maximum possible value is 48. | 9 months | |
Secondary | Fine Motor Scale, Bayley Scales of Infant Development, 3rd Edition | The Fine Motor Scale is a single scale that measures prehension, perceptual-motor integration, motor planning and speed, visual tracking, reaching, object grasping, object manipulation, functional hand skills, and responses to tactile information. Higher values represent better performance. The interquartile range provides adequate assessment of the variability of the data. The minimum possible value is 0 and the maximum possible value is 66. | 9 months | |
Secondary | Gross Motor Scale, Bayley Scales of Infant Development, 3rd Edition | The Gross Motor Scale is a single scale that measures movement of the limbs and torso, static positioning (e.g., sitting, standing), dynamic movement including locomotion and coordination, balance, and motor planning. Higher values represent better performance. The interquartile range provides adequate assessment of the variability of the data. The minimum possible value is 0 and the maxiumum possible value is 72. | 9 months | |
Secondary | Kaufman's Assessment Battery for Children (KABC) | This test is used for assessing child intelligence | 60-72 months | |
Secondary | The Wechsler Preschool and Primary Scale of Intelligence (WPPSI) | WPPSI is an intelligence test designed for children ages 2 years 6 months to 7 years 7 months. It is a paper-pencil test that will be administered during the 78 month follow up to assess child's intellectual functioning. | 78 months | |
Secondary | Vineland Social Maturity Scale (VSMS) | This scale has 8 main domains which include, Self Help General, Self Help Dressing, Self Direction, Occupation, Communication, Locomotion and Socialization. It is possible to calculate Social age and Social quotient from VSMS which will provide a good idea about the social maturity of the infant. VSMS will be used in conjunction with KABC at age 60-72 months of age. | 60-72 months | |
Secondary | The Brief P Test | The Brief P test is a measure of infant executive function based on parental rating. It will be administered at 66 months postpartum. | 66 months postpartum | |
Secondary | Parental Version of Strengths and Difficulties Questionnaire (SDQ) | Administered at 78 months to assess childhood behavioral problems. The SDQ has 25 items and generates 5 scales: emotional problem, conduct problem, hyperactivity/inattention, peer relationship problems and pro-social behavior. | 78 months | |
Secondary | Bradley Infant-Toddler Home Tools | Home tools used to analyze aspects of home environment. This scale captures information on parenting behavior under 6 domains: responsivity, acceptance, organization, learning materials, parental involvement, and variety of stimulation at home).
