Family psychological history, PSS: Sights and Sounds, and PSS: Looks and Behavior, state anxiety, primipara status and maternal age were associated with PPTS symptoms at T1 at p<.10 but did not maintain significance at p<.15 in the regression, so were not retained in final regression model

Family psychological history, maternal psychological history, PSS: Sights and Sounds, PSS: Looks and Behavior, PSS: Maternal Role Alteration, state anxiety, history of fetal loss and maternal age were associated with PPTS symptoms at T2 at p<.10 but did not maintain significance at p<.15 in the regression, so were not retained in final regression model

Family psychological history, maternal psychological history, PSS: Sights and Sounds, PSS: Looks and Behavior, PSS: Maternal Role Alteration, state anxiety, DS at T1, history of fetal loss, relationship status, birthweight and number of days on mechanical ventilation were associated with elevated PPTS symptoms at T2 at p<.10 but did not maintain significance at p<.15 in the regression, so were not retained in final regression model.
