Parental measures included trait anxiety measured by the State-Trait Anxiety Inventory (STAI) and well-being measured by the General Health Questionnaire (GHQ).', "Maternal trait anxiety was associated with a less optimal neurological condition (r(s)= -0.19, p<0.01) of the infant.

Paternal trait anxiety and parental well-being were not related to the infant's neurodevelopmental outcome."] Is maternal anxiety related to infant neurological condition , paternal anxiety is not?
