Interaction effect of mFICare parent classes and parent NICU stress and on PTSD symptoms (3a) and depression (3b) after NICU discharge. Dotted lines indicate the 95% confidence interval for each group. a. Mothers with higher levels of NICU-related stress who attended at least one parent class had lower post-discharge PPQ scores than similarly stressed mothers who did not attend classes; mothers with lower levels of NICU-related stress had relatively few PTSD symptoms, regardless of class attendance (p = .024). b. Mothers with higher levels of NICU-related stress who attended at least one parent class had lower post-discharge EPDS scores than similarly stressed mothers who did not attend classes; mothers with lower levels of NICU-related stress had relatively few depression symptoms, regardless of class attendance (p = .015)
