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? FAST showed a small statistically significant negative effect on family conflict for Cohort 2 at end of Grade 1 (effect size .26 SD), not found for Cohort 1 or other time points, and may be spurious. → Bos 2018

Evidence

Bos 2018

Bos, J., Spier, E., Bandeira de Mello, V., González, R., & Huang, F. (2018). Investing in Innovation (i3) Validation Study of Families and Schools Together (FAST) Final Report. American Institutes for Research. https://evidenceforessa.org/program/families-and-schools-together-fast/

q3 · i? · causal · r3

RCT analysis using the Child-Parent Relationship Scale Conflict subscale found a negative effect of ".26 SD" for Cohort 2 at Grade 1 only; no effect on the Closeness subscale or at other time points, so the authors judged it possibly spurious.

"offering FAST had a small yet statistically significant negative effect on family conflict for Cohort 2 at the end of Grade 1 (effect size .26 SD), meaning that families in Cohort 2 in FAST treatment group schools reported more conflict than families in control group schools who were not offered FAST."
