Subclaims¶

q3 i3 The VIQ–NVIQ split × condition interaction was significant for Social Cognition, Communication, and Motivation; for students with lower VIQ than NVIQ, SCI-A had positive effects on social communication (d = −0.97) and motivation (d = −1.34). → Stichter 2018 q3 i3 For students with VIQ at least 11 points higher than NVIQ, SCI-A was less effective on social cognition (d = 1.23), communication (d = 1.10), and motivation (d = 1.95). → Stichter 2018

q3 · i3 · causal · r2

Multilevel moderation analysis of the CRT probing the VIQ–NVIQ split at −11 and +11, with FSIQ as covariate. Interactions were significant for Cognition (p = .004), Communication (p = .036), and Motivation (p = .043), with large simple-slope effect sizes in both directions.

"for groups characterized by a lower verbal than nonverbal abilities (i.e., VIQ at least 11 points lower than NVIQ), SCI-A students had lower SRS-2 scores relative to BAU students, suggesting SCI-A had a positive effect on these students’ social communication (d = −0.97) and motivation (d = −1.34) to be social."

Discussion¶

Related Claims¶

• FSIQ significantly moderated SCI-A response only on communication, where lower-FSIQ students did better in SCI-A than in BAU and higher-FSIQ students did worse — related
• SCI-A and BAU showed no significant differences on most SRS-2 subscales at postintervention, with BAU significantly better on Social Cognition (d = 0.31) — related
• VIQ moderated SCI-A response: lower-VIQ students benefited on communication, while higher-VIQ students showed worse outcomes on social cognition, communication, and motivation — related
