Factor Structure, Internal Consistency, and Screening Sensitivity of the GARS-2 in a Developmental Disabilities Sample

Table 4

Correlations between factor-based scales and GARS-2 subscales.

	GARS-2; Stereotyped Behaviors; subscale	GARS-2; Social Interaction; subscale	GARS-2; Communication; subscale
Factor I: Stereotyped and Repetitive Behaviors	.97	.81	.73
Factor II: Social Avoidance and Withdrawal	.68	.91	.79
Factor III: Atypical Language and Communication	.51	.57	.87

Note. Raw sums of item scores were used to calculate the factor-based scales and GARS-2 subscale scores. In the case of the factor-based scales, only items with primary loadings ≥.40 were used in the composite. Correlations on the diagonal are convergent and correlations on the off diagonal are divergent.
