Eugene and Ulrich, thanks for your valuable suggestions. I have tried looking at the individual items of the problem predictor variable "Interpersonal communication and care" and their correlations with DV through Phi correlations (individual items were measured at binary level). It seems that the items which pertain to interpersonal care for instance "were you treated with respect and courtesy?" have high correlations with DV  (.4 to .61)whereas the items of this same factor which pertain to communication part such as "were you given sufficient information regarding care of the newborn?" have moderate correlation with DV( ranging from .2 to .4). I want you to note that the DV was measured using a single item worded as "All in all, were you satisfied with the services you received during your stay in the hospital?" with response options of yes and no. As far as I can think, I don't see any replication of ideas here. But one particular item of the factor "do you think that the healthcare personnel took care of you and your child?" may have been interpreted in the same sense as the question measuring DV. This particular item has a phi correlation of .61 with DV and also very few responses in one cell. Should I try removing this item, calculate the factor score again, dichotomize and look at the changed odds ratio ?
