Primary aim results of a clustered SMART for developing a school-level, adaptive implementation strategy to support CBT delivery at high schools in Michigan

Table 3 School-level characteristics by phase 1 randomization (Coaching vs. no Coaching) (N = 94 schools)

	All schools (N = 94)	REP (N = 47)	REP + Coaching (N = 47)
Proportion of schools with >500 students (vs. ≤ 500 students)	0.65	0.66	0.64
Proportion of rural schools (vs. non-rural)	0.56	0.55	0.57
Proportion of schools with >50% students on free/reduced lunch program (vs. ≤ 50%)	0.36	0.36	0.36
Proportion of schools with any pre-randomization CBT delivery (vs. none)	0.57	0.55	0.60
School-level average SP tenure in years: mean (SD)	7.56 (5.96)	7.34 (6.03)	7.79 (5.94)
School-level proportion of SPs with graduate degree: mean (SD)	0.90 (.26)	0.89 (.28)	0.91 (.24)
Number of SPs per school	Mean = 1.80	Mean = 1.72	Mean = 1.87
	1 SP: N = 38	1 SP: N = 21	1 SP: N = 17
	2 SPs: N = 37	2 SPs: N= 18	2 SPs: N = 19
	3 SPs: N = 19	3 SPs: N = 8	3 SPs: N = 11

All variables other than the number of SPs were included as covariates in regression models. Data on school size, geography, and free/reduced lunch were derived from baseline school administrator surveys and/or state data sources (e.g., MI School Data; https://www.mischooldata.org/); SP tenure and education from SP baseline surveys; and pre-randomization CBT delivery from SP weekly CBT reports during the pre-randomization run-in phase
