Question
7. Maternal role adaptation was compared in a group of mothers of low birth-weight
(LBW) infants who had been in an experimental intervention, mothers of LBW
infants who were in a control group, and mothers of full-term infants. Using SPSS,
researchers performed an ANOVA to see if there is a difference in adaptation
between the groups. They got the following results:
