Table 3

Correlations between scores on the Griffiths scales, the Movement ABC, and the WPPSI

Griffiths scores	Movement ABC	WPPSI
Griffiths scores	Total Score†	Full Scale IQ
Pearson correlation coefficients: *p<0.001, p<0.05.
†On the Griffiths scales a higher score indicates better performance, while on the Movement ABC a higher score indicates poorer performance. Positive correlations therefore yield a negative coefficient. The negative sign has been omitted in this table.
