Are collaborations among several nursing schools more desirable than single-school interventions?
Collaborations among schools can strengthen the evaluation by assuring that the intervention group (e.g., students, faculty) is large enough to permit isolation of its impact on outcomes (i.e., yielding adequate statistical power). For such collaborations to be effective, the intervention must be implemented with a high degree of uniformity at each site — faithful replication is crucial. Another way in which collaborations with other schools can be helpful is that they may offer appropriate comparison groups for your evaluation design.
