The mean of mental health outcomes assessed by IES, GHQ and STAI-X1 at the infant's 6- and 18-month post-term ages was used as outcome. Unstandardized (B) and standardized (beta) regression coefficients from multiple linear regression analyses after forward stepwise variable selection are reported. N = 33. aThe child was struck by intraventricular haemorrhage grade 1 or 2 shortly after birth; bTen-question version of STAI-X1.
