Long-term Follow-up of Children Born in the PETN Studies

The Child Behavior Checklist comprises items assigned to 8 subscales describing various behavioral areas. These subscales can be summed up to scores for internalizing and externalizing problems as well as a total score. Checklist scores are reported on a T-scale. Range of T-scale from scores 20 to 100 (average performance between scores 40 and 60). Higher scores mean higher amount of problems.

The Questionnaire Young Self Report comprises items assigned to 8 subscales describing various behavioral areas. These subscales can be summed up to scores for internalizing and externalizing problems as well as a total score.

physical development examination including height (in cm), weight (in g) and tanner states

metabolic development using blood analysis including blood components, metabolic parameters (Glucose, HbA1c, cholestrol)

"The RIAS is standardized intelligence test. The RIAS provides an Total Intelligence Index (GIX, estimate of the general intelligence/g-factor), Verbal Intelligence Index (VIX) and the Nonverbal Intelligence Index (NIX). Test scores are reported on a T-scale. Range of T-scale from scores 20 to 100 (average performance between scores 40 and 60). Higher scores mean better cognitive performance."

neurocognitive development

"The M-ABC-2 is an standardized test to assess the motoric development. Adding up subscores addressing manual dexterity, aiming and catching, and balance delivers a total score of the motoric performance.~Test scores are reported on a T-scale. Range of T-scale from scores 20 to 100 (average performance between scores 40 and 60). Higher scores mean better performance."

The CPT measures selective attention, sustained attention as well as impulsive behavior. Checklist scores are reported on a T-scale. Range of T-scale from scores 20 to 100 (average performance between scores 40 and 60). Higher scores mean worse performance.

The FBB-ADHS assesses a total score for ADHD-like behavior and subscores for the symptom trias of ADHD (attention deficit, motoric hyperactivity as well as impulsive behavior, Questionnaire scores are reported on a T-scale. Range of T-scale from scores 20 to 100 (average performance between scores 40 and 60). Higher scores mean higher amount of symptoms.

urine examination (proteomics, cytokines, lipidomics)

The FTF 5-15R is a questionnaire to evaluate the child's developmental outcome in different areas of everyday life (cognition, language, and motor impairment as well as social, emotional, and behavioral problems). Individual item scores are added up per area and divided by the number of items. This results in a common scale value. Range of Percentile scores from 0 to 100 (0-90: no developmental problem; 90 and higher: hint for developmental problem). Higher scores mean worse developmental outcome.
