q2 i? Contrary to the expectation of fewer family obligations (H4), intervention students reported slightly higher state family obligations than Control Group 2 at T2, and the difference did not persist at 12 months. → Jiang Su 2026

q2 · i? · causal · r2

In the propensity-weighted latent state treatment-effects models, the family-obligations finding ran opposite to the pre-registered direction: intervention students reported slightly higher state family obligations at T2 versus Control Group 2, dissipating by 12 months. No effect size was printed.

"Contrary to our expectations, relative to students in the intervention, those in Control Group 2 expressed slightly lower state Family Obligations at T2, but state Family Obligations did not differ by the 12-month follow-up (H4 not supported)."
