A randomized block design with repeated measures is being used. Subjects at each of two study sites are randomly assigned to the COPE or comparison group by 4-week periods of time. Using random assignment at each site will allow for assessment of an interaction effect as part of the data analytic strategy. Based on the average NICU stay in the pilot study (mean = 29.6 days), the decision to use 4-week blocks of time was made to decrease the likelihood of parent to parent and staff to parent contamination which would be more likely with individual randomization.
