Objective:
To determine the efficacy of an individualized, family-based intervention with preterm infants and their families.
Design:
Randomized, repeated measures intervention outcome study.
Setting:
Level III neonatal intensive care nursery.
Patients:
Random sample of 34 preterm infants < or = 1500 g and their families.
Interventions:
Individualized, family-based intervention during the hospitalization and transition to home addressed problems identified by parents in four domains including: infant behavior and characteristics, family organization and functioning, caregiving environment, and home discharge and community resources.
Measurements And Main Results:
Standardized questionnaires were administered at baseline and discharge to mothers, and predischarge bottle-feeding interactions were videotaped and coded by two blinded observers. Results were in favor of intervention (Int) versus control (Con) mothers (baseline; discharge) (P < .05) on the Parental Stressor Scale Sights and Sounds subscale (Int 2.4 +/- 1.0; 2.0 +/- 0.8 vs Con 2.4 +/- 0.9; 2.6 +/- 0.8); Child's Appearance and Behavior subscale (Int 2.8 +/- 1.0; 2.5 +/- 1.1 vs Con 2.8 +/- 0.8; 3.1 +/- 0.6); and Total Stressor Score (Int 93.9 +/- 36.6; 72.3 +/- 41.8 vs Con 87.5 +/- 26.7; 87.8 +/- 26.2). On the Beck Depression Inventory, intervention mothers had significant decreases in depressive symptoms (39%; 11%) vs control mothers (31%; 44%). Maternal self-esteem in both groups improved over time. There were no significant group differences in family environment. During feeding interactions, intervention infants grimaced (P < .001) and gagged (P < .05) less than controls. Intervention mothers less frequently interrupted feedings (P < .001); less frequently stimulated infant sucking (P < .01); smiled more (P < .001); vocalized more (P < .01); demonstrated greater sensitivity to infant behavior (P < .001), better quality of physical contact (P < .001), and more positive affect (P < .01).
Conclusions:
Individualized, family-based intervention appears to reduce maternal stress and depression, and to enhance early mother-infant feeding interactions. Further research is needed to determine whether these short-term beneficial effects persist beyond the newborn period.
