56 Month Follow Up

At 56 months, a clinical and neurological examination was carried out to assess height, weight, head circumference, neurological measurements, cerebral palsy, and visual and hearing impairment.

Cognitive Assessments performed included the Columbia Mental Maturity Scale (CMMS), Beery Developmental Test of Visual-Motor Integration - Revised (Beery VMI), the Finnish translation of the Aktiver Wortschatztest (AWST) to assess verbal competence, and the Logopädisher Sprachverständnis Test (LSVTA) to assess language comprehension.

Parents of the participants also completed the Family Adversity Index (FAI) and Psychosocial Stress Index (PSI) questionnaires and were interviewed about the participants' sleep problems. The assessor also provided ratings of parent behavior, parent-child interactions and child behavior based on observation of the dyad.
