COVID - 19, Preterm Infant Development
Conditions
Brief summary
This study aims to evaluate differences in cognitive and psychomotor development among preterm infants (born before 34 weeks of gestation) delivered during the COVID-19 pandemic at Hospital de la Santa Creu i Sant Pau, compared with a control group of preterm infants born at the same hospital.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Bayley Scales Of Infant and Toddler Development | All scores on this scale will be collected at the following ages for every child: - 3 months - 6 months - 12 months - 18 months - 24 months | It aims to evaluate the child's level of development in different areas. Through structured tasks and materials but in a playful format, it allows to obtain a global score of cognitive, motor and language development. From the direct scores of the scale, it is possible to obtain scalar, composite and percentile scores. The scaled scores are calculated from the direct scores of each test. They have an average of 10 and a standard deviation of 3. They represent the child's performance in relation to children of his same age. The composite scores are typical scores obtained from scales with a mean of 100 and a standard deviation of 15. From these, the corresponding percentiles can be obtained in the tables included in the manual. |
| Wechsler Preschool and Primary Scale of Intelligence | All scores on this scale will be collected at the following ages for every child: - 3 years old - 5 years old | It allows a complete measurement of the subject's cognitive abilities. Through structured tasks, standardized scores are obtained for the overall cognitive capacity, as well as for the verbal, manipulative, processing speed and general language indices. In this study we will collect typical scores, composites and percentiles of each of the subtests and indexes of the Scale. For this, based on the direct scores of each subtest, the typical scores are obtained whose mean is 10 and standard deviation 3. These scores allow inter-individual comparison. On the other hand, with several subtests the composite scores are formed, which correspond to the indices of the WPPSI-III (Verbal CI, Manipulative CI, Processing Speed, General Language and Total CI). The composite scores are converted to a scale of mean 100 and standard deviation of 15. In addition, the WPPSI-III offers percentiles for the scores of the subtests and for the indices. |
