Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? The percentage of students with a major or minor ODR decreased significantly in SWPBIS schools, though the printed effect size was very small (d = .08). → Catherine P. Bradshaw 2010
q3 i? The number of major and minor ODR events per student also decreased significantly over the trial. → Catherine P. Bradshaw 2010 (2)
Evidence¶
Catherine P. Bradshaw 2010¶
Catherine P. Bradshaw, Mary M. Mitchell, & Philip J. Leaf. (2010). Examining the Effects of Schoolwide Positive Behavioral Interventions and Supports on Student Outcomes: Results From a Randomized Controlled Effectiveness Trial in Elementary Schools. Journal of Positive Behavior Interventions, 12(3), 133-148. https://doi.org/10.1177/1098300709334798
q3 · i? · within-school pre-post change only, d = .08; no treatment-control effect size · causal · r2
Repeated measures GLM on SWIS ODR data from SWPBIS-trained schools only (no baseline or comparison ODR data; SWIS use was part of the program). The percentage fell "from 18.8% to 18.1%" with d = .08.
"the percentage of students with a major or minor ODR decreased significantly over the course of the study from 18.8% to 18.1%, Wilks's Λ = .67, F(1, 14) = 6.99, p = .019, η2 = .33, d = .08"

q3 · i? · within-school pre-post change only, d = .12; no treatment-control effect size · causal · r2
Second GLM analysis of SWIS ODR data from the SWPBIS schools across the four posttraining years, showing a significant decline in ODR events per student with d = .12.
"The number of major and minor ODR events per student also decreased significantly over the course of the trial, Wilks's Λ = .52, F(1, 14) = 12.90, p = .003, η2 = .48, d = .12"
Discussion¶
Related Claims¶
- SWPBIS reduces the odds of receiving an office discipline referral — the general claim this finding bears on, with the studies behind it¶
- At-risk children in SWPBIS schools are slightly less likely to receive an office discipline referral than at-risk peers in comparison schools (41.3% vs 46.5%, d = -0.13) — related
- School suspension rates declined significantly within SWPBIS schools but not within comparison schools, though the two conditions were not tested against each other — related
