Summary

Author (yr) Sample Size Topic(s) Addressed Outcome
Gray, Tonge, Sweeney, & Einfeld, S. (2008) 207 - Age Range: 20-51 months Reliability Validity Internal consistency Inter-rater reliability Sensitivity and specificity

Inter-rater reliability: between parents (interclass correlation of 0.772 p<0.01)

Validity: Total score correlated with ADI-R Social domain (r = 0.47, p <0.01), Verbal Communication domain (r = 0.36, p<0.01), Non-verbal Communication domain (r=0.37, p<0.01), and Restricted and Repetitive domain (r= 0.53, p<0.01)

Internal consistency: Cronbach’s =0.87 Inter-rater reliability: r=0.772 (p<0.01)

Sensitivity and specificity: Using cut-off score of > 11 sensitivity = 0.83 (95% CI: 0.76-0.89) and specificity of 0.48 (95% CI: 0.35-0.60)
