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

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

  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
  1. 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
