Subclaims¶

q3 i3 Wages differed greatly between groups (d = 2.00 at graduation, 3.16 at 3 months, 2.74 at 12 months), driven by employment differences. → Wehman P 2017 q3 i? When unemployed participants were excluded (8 control, 23 treatment), the wage model was not significant (p = 0.191). → Wehman P 2017 (2)

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 wages in the RCT found significant group × time interaction (F(3,138) = 31.92, p < 0.0001); mean treatment wages rose from US$7.01 at graduation to US$8.61 at 3 months, versus US$0.53 for controls. The article reports "large differences in standardized effect sizes (d)" of 2.00–3.16.

"There were large differences in standardized effect sizes (d) between the treatment and control groups at each time: 2.00 (graduation), 3.16 (3 months), and 2.74 (12 months), respectively."

q3 · i? · causal · r2

Sensitivity analysis of the same RCT wage model excluding unemployed participants (8 control, 23 treatment) found no significant wage difference; employed participants in both groups earned similar hourly wages (treatment US$9.53–10.66; control US$9.67–10.00).

"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 = 0.191)."

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
• Weekly hours worked rose significantly for employed PS-ASD participants from graduation to 12-month follow-up (d = 2.17), while control hours did not change — related
• Employment support intensity needs decreased significantly over 21 months for the treatment group while remaining unchanged for controls, but not when unemployed participants were excluded — related
