E.5 End points |
E.5.1 | Primary end point(s) |
The primary end point is developmental pace. Development is assessed by the Bayley-III-NL (Dutch version of the Bayley-III, Bayley, 2006) or WPPSI-III-NL (Dutch version of the WPPSI-III, Wechsler, 2009) dependent on the developmental age of the children. Both the Bayley-III and the WPPSI are individually administered tests that provide subtests and composite scores that represent general functioning. Developmental pace is calculated as the difference in developmental age equivalent between two assessments divided by the difference in calendar age in months at the time of these assessments (typically 6 months), resulting in a value for developmental age increase / month. |
De primaire uitkomstmaat is ontwikkelingssnelheid. Ontwikkeling wordt getest met behulp van de Bayley-III-NL (Nederlandse versie van de Bayley-III) of WPPSI-III-NL (Nederlandse versie van de WPPSI-III) afhankelijk van de ontwikkelingsleeftijd van de kinderen. Zowel de Bayley-III als de WPPSI zijn individueel toegepaste testen die subtesten en composiet scores geven welke representatief zijn voor het algemeen functioneren. Ontwikkelingssnelheid wordt berekend als het verschil in ontwikkelingsleeftijd equivalent tussen twee testen gedeeld door het verschil in kalenderleeftijd op het moment van de testen (typisch 6 maanden), resulterend in een waarde voor de toename in ontwikkelingsleeftijd / maand. |

6, 12, 18 months after initiation of the clinical trial phase |
6, 12, 18 maanden na het begin van de clinical trial phase |
|
E.5.2 | Secondary end point(s) |
The secondary end point is behaviour. Behaviour is assessed by the following questionnaires: Vineland screener, ESSEON, CBCL1,5-5, and Brief-P. To evaluate behaviour in several domains, raw scores are determined.
|
De secundaire uitkomstmaat is gedrag. De secundaire uitkomstmaat is gedrag. gedrag wordt getest met behulp van de volgende vragenlijsten: Vineland screener, ESSEON, CBCL1,5-5 en Brief-P. Om het gedrag te evalueren op verschillende gebieden zullen ruwe scores bepaald worden.
