How Do Mothers Feel About Their Very Low Birth Weight Infants? Development of a New Measure.

The early relationship between a mother and her very low birth weight (VLBW; <1.5 kg) infant may be difficult to evaluate. Therefore, we aimed to develop a useful and practical method to describe a mother's early relationship with her VLBW infant. Mothers (mean age=27 years, 46% married) of 119 singleton VLBW infants (mean BW=1,056 g, mean GA=28 weeks) admitted to the neonatal ICU at Rainbow Babies and Children's Hospital completed a novel questionnaire regarding their feelings about their infant at 3 weeks' postnatal age, and at 35 weeks', 40 weeks' (term), and 4 months' postmenstrual ages. Factor analysis of initial interview data was used to construct subscales to measure unique domains hypothesized to underpin the beginning maternal-infant relationship. Three subscales were identified: (a) The Worry subscale focuses on the mother's concerns about her infant's current medical condition and future development, (b) the Enjoyment subscale examines the mother's positive feelings about and responsiveness to her infant, and (c) the Separation Anxiety subscale examines the mother's mental anxiety about being physically separated from her infant. Statistical and clinical validation of the subscales produced positive supporting evidence that the subscales are a meaningful measure of the mother-infant relationship. We have developed a unique and practical measure for describing the early mother-VLBW infant relationship.
