q2 i? Students in Control Group 2 (non-responders) reported slightly lower state parental support than intervention students at T3; the difference versus Control Group 1 was not reported as significant. → Jiang Su 2026

Jiang Su 2026¶

q2 · i? · causal · r2

From the propensity-weighted latent state models of the longitudinal quasi-experiment, parental support effects emerged at the 12-month follow-up (T3) only against Control Group 2, the group of parents "not interested or reachable". H3 was only partially supported, and no effect size was printed.

"Relative to students in the intervention, those in Control Group 2 expressed slightly lower state Parent Support at T3 (H3 partially supported)."

Discussion¶

Learner Variables¶

• Social Supports — outcome: instruction changes it
