Dose-Response Threshold in Non-Cognitive Interventions
Observational StudyClinical Trial
Low compliance and attendance in voluntary socio-emotional interventions obscure overall program impacts unless evaluated across explicit attendance thresholds.
Picture this
Taking a single dose of an antibiotic does not cure an infection, whereas completing the full prescribed treatment course eliminates the illness. Similarly, attending one support session provides negligible skill building, but crossing a minimum threshold of multiple sessions unlocks substantial behavioral improvement.
What the evidence says
Attending 1 to 4 CBT sessions increased 11th-grade enrollment by 7.4 percentage points (p < 0.01), while attending 5 or more sessions increased 11th-grade enrollment by 19.0 percentage points (p < 0.01) and overall student engagement by 12.1 percentage points (p < 0.01).
- Who was studied
- N = 4,632 upper secondary students evaluated using multi-valued treatment matching models across 20 schools in Mexico City.
- How
- Regression-adjusted inverse probability weighting (RAIPW) matching model comparing 0 sessions, 1 to 4 sessions, and 5 or more sessions against the control group.
What to do
Incorporate active attendance tracking and minimum participation milestones of at least 5 sessions when implementing voluntary socio-emotional programs.
From the source
"For students attending 5 or more CBT sessions, the probability of enrolling in 11th grade increases by 19 percentage points."
