Table 4.
Correlation coefficient (r) between each composite score (SPA, PRO, and KIN) obtained from the performance in the tablet-based ROCF copy task and study participants’ age as well as paper-and-pencil ROCF copy accuracy, ROCF copy strategy, Beery VMI, and BVSCO-3. Statistically significant p values are reported with an asterisk: *p < 0.05; **p < 0.01; ***p < 0.001. A correlation coefficient of 0.10 represented a weak or small association62; a correlation coefficient of 0.30 was considered a moderate correlation62; and a correlation coefficient of 0.50 or larger represented a strong or large correlation62 (bold r values).

1Scores obtained from participants’ performance in the three paper-and-pencil tests that are part of the BVSCO-3 battery are reported.
2For 92/94 study participants, performance in the conventional paper-and-pencil Beery VMI and BVSCO-3 tests was compared with each composite score (SPA, PRO, and KIN).
