The intercorrelation between the two tests was compared to in the three different domains (Reciprocal Social Interaction, Communication, and Restricted, Repetitive, and Stereotyped Patterns of Behavior).
Reciprocal Social Interaction, the intercorrelation value was .92
Communication value of .73
Restricted, Repetitive, and Stereotyped Patterns of Behavior value was .89
However, the item-by-item agreement was not in agreeance. According to the manual, “ADI-R items were classified as present if the score was 1, 2, or 3; these were then compared with scores of 1 on the SCQ.” Agreement Ranged from 45% to 85% with an average of 70.8%.
