^aHigher scores indicate greater service availability (3 = performed in-house, 2 = done by contract workers, 1 = not available).

^bIn pairwise comparisons, all overall service cluster means are significantly different from one another (p < .001 for all).

^cService availability mean scores in lighter shading within a row (i.e., by staffing cluster) are not significantly different from one another in mean score; however, a service availability score in darker shading differs significantly in mean score from each of the other staffing clusters in that row (i.e., p values for pairwise comparisons range from <.001 to <.05).
