The researchers used a randomized control trial with the control group receiving standard nursing care and the intervention group receiving unlimited kangaroo care (Hake-Brooks & Anderson, 2008). “The computerized minimization method was used to random assignment. This method increases statistical power by decreasing between-group variance (Hake-Brooks & Anderson, 2008, p. 153).” The researchers conducted follow up telephone interviews at six weeks and three months (Hake-Brooks, 2008). In person follow up occurred at six, 12 and 18 months (Hake-Brooks & Anderson, 2008) adding to the consistency of the findings. To accurately define breastfeeding status, Hake-Brooks & Anderson (2008) used the Index of Breastfeeding Status (IBS) to provide credible and consistent results. According the Hake-Brooks & Anderson (2008), a contact log and the Index of Mother-Infant Separation (I-MIS) were used to document the amount of kangaroo
