Main intervention effects and moderators
Stress Disorder, depression, Depression, PTSD
INTERACTION
As shown in Table Of the four potential moderators evaluated, there was no evidence that the intervention was differentially associated with the infant’s gestational age, infant age when mFICare was started, or whether the infant was discharged on a feeding and/or respiratory device (tested with an interaction effect, p > .05). However, we found a nominally significant interaction association between PSS:NICU scores and intervention group for PPQ (interaction β=-1.18, 95% CI: -2.10, -0.26; p = .012; Table
