Does the ESI measure early social competence and play skill?
Correlations were positive, ranging from poor to moderate in size (also see Correlation Table below): • Correlations between the Vineland’s interpersonal and play/leisure scales and the PVSB mean intercept value were moderately large at .65, and .62, respectively. • Vineland scale corrleations with the Positive NonVerbal Social Behavior (PNVSB) intercept value were smaller at .39, and .29, respectively. • Vineland scale corrleations with the PositiveTotal Social Behavior (PTSB) intercept value were .45, and .52, respectively. • Correlations between the Howes simple social play scale and overall composite were positive and moderately large correlates of the PVSB mean intercept value (r = .47 and r = .34, respectively) • Similar significant correlations were observed between the Howes parallel/mutual scale and the overall composite and the PNVSB scale (r = .44 and r = .33, respectively).
