Development of a Clinical Rating Scale to Assess Mother-Infant Interaction in a Psychiatric Mother and Baby Unit

Using the BMIS facilitated attempts to reliably assess disturbances of mother-infant interaction and the scale was acceptable and clinically useful. The nurses' ratings of their perceptions of 'risk' to the infant, which are in some ways the most important, were the least reliable. Repeated weekly ratings gave a valuable impression of change or lack of it over time. The predictive validity of the scale has yet to be determined.
