A Method for Universal Screening of Social Challenges in Elementary School Students
Objectives: To empirically develop and test the SCSQ, which is appropriate for universal screening in elementary schools.
Methods: The development phase included 30 participants (28 males) diagnosed with ASD after age 6 years (ages 6 to 54 years; M = 19.55, SD = 10.93) and one parent informant.. Diagnosis of ASD was confirmed with ADI-R, ADOS, Vineland 2, and Stanford-Binet 5. Participants for the validation phase were 35 teachers from eight charter schools who completed the SCSQ on 549 general education students (ages 8 to 11 years, M = 9.51, SD = 0.65). Students with scores in the upper 2.5% of the distribution (n = 15) and a comparison sample of students (n = 35) from the lower end of the distribution, were selected for follow-up assessment with the Social Responsiveness Scale 2. The subsample (n = 50) consisted of 33 males and 17 females (ages 8 to 11 years of age; M = 9.42, SD = 0.67).
Results: Scores on the SCSQ ranged from 0 to 14 (M = 1.38, SD = 2.42) and every item was endorsed by this sample. Cronbach’s alpha was .85. Inter-item correlations ranged from .008 to .638 and the deletion of any one item did not change reliability substantively in either direction (range =.82 to .85). In the subsample of 50 students, total scores on the SRS-2 ranged from 2 to 167 (M = 60.22, SD = 41.13) and were significantly correlated (r = .87, p < .01) with the SCSQ. An ROC curve was applied to compare the SCSQ to an SRS-2 dichotomy (0 = unaffected, 1 = affected) which indicated an optimal threshold score of 6 to yield a sensitivity of .94 and a specificity of .88.
Conclusions: Just as screening for vision and hearing impairments can lead to a referral to a specialist, the SCSQ should lead to a referral for formal evaluation for ASD. Then, students with mild impairments can be identified early within schools and enrolled in appropriate evidence-based intervention programs. The combined effect of universal screening, skilled evaluation, and early intervention may help to improve academic and long term functioning for students with social challenges.
