The Mother and Baby Interaction Scale: a valid broadband instrument for efficient screening of
postpartum interaction? A preliminary validation in a Norwegian community sample
Sammanfattning
Background and aims: The mother-infant relationship may represent a risk or a protective factor for child development. Hence, an early focus on the relationship may be a worthwhile preventive measure. A simple 10-item instrument, the Mother and Baby Interaction Scale, could be a convenient screening instrument for early bonding failure. In this pilot study, preliminary indications of the internal consistency, stability, principal components validity of the Mother and Baby Interaction Scale were investigated.
Methods: Seventy-six postpartum women participated. The Mother and Baby Interaction Scale and Postpartum Bonding Questionnaire were completed together with the Edinburgh Postnatal Depression Scale. The internal reliability of the Mother and Baby Interaction Scale, and its correlations with the Postpartum Bonding Questionnaire and Edinburgh Postnatal Depression Scale, was examined. Principal component analysis of the Mother and Baby Interaction Scale was conducted, and the emerging subscales were compared with the Postpartum Bonding Questionnaire.
Results: The principal component analysis yielded four subscales: Bonding problems, Worries about caretaking, Regulation and routine and Sensitivity and separation. We found acceptable internal consistency of the Mother and Baby Interaction Scale. The total score of the Mother and Baby Interaction Scale correlated better (r = 0.72) with the Postpartum Bonding Questionnaire than the four subscales. The correlation between the total scores of the Edinburgh Postnatal Depression Scale and the Mother And Baby Interaction Scale was r = 0.49.
Conclusions: The total score of the Mother and Baby Interaction Scale is a promising measure for early screening of the quality of the mother-infant relationship and is suitable for general practitioners, midwives and other health workers dealing with postpartum women and their children.
