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. ^{a}The child was struck by intraventricular haemorrhage grade 1 or 2 shortly after birth;
^{b}Ten-question version of STAI-X1.
