Subclaims¶

q3 i3 Treatment participants employed at graduation worked significantly more hours at 12-month follow-up than at graduation (t = −3.29, p = 0.027, d = 2.17). → Wehman P 2017 q3 i? When unemployed participants were excluded, the hours-worked model was not significant (p = 0.362). → Wehman P 2017 (2)

Evidence¶

Wehman P 2017¶

Wehman P, Schall CM, McDonough J, Graham C, Brooke V, Riehle JE, Brooke A, Ham W, Lau S, Allen J, Avellone L. (2017). Effects of an employer-based intervention on employment outcomes for youth with significant support needs due to autism. Autism 21(3), 276–290. https://doi.org/10.1177/1362361316635826

q3 · i3 · causal · r2

Mixed repeated measures analysis of hours worked in the RCT found a significant group × time interaction (F(3,140) = 325.88, p < 0.0001); employed treatment participants rose from a mean of 15.24 h weekly at graduation to 19.90 h at 12 months, while control hours stayed near 1.25–2.50 h.

"Additionally, the treatment group worked significantly more hours at the 12-month follow-up compared to the hours worked at graduation (t = −3.29, p = 0.027) with a large standardized effect size (d) of 2.17."

q3 · i? · causal · r2

Sensitivity analysis of hours worked excluding unemployed participants (8 control, 23 treatment) was not significant, indicating the between-group hours difference repeats the employment outcome difference.

"When all participants who were unemployed were taken out of the analyses, this left 8 participants in the control group and 23 participants in the treatment group, and the model was not significant (p = 0.362)."

Discussion¶

Related Claims¶

• PS-ASD participants acquired community-based competitive employment at far higher rates than high-school-services-as-usual controls (90.3% vs 5.9% at 3 months; 87.1% vs 11.1% at 12 months) — related
• PS-ASD participants earned substantially higher wages than controls, but the wage difference was not significant when unemployed participants were excluded — related
