Correlations before (below diagonal) and after (above diagonal) adjustment for reliability of the variables
1 | 2 | 3 | 4 | 5 | |
---|---|---|---|---|---|
1. Mazes difference | (.55) | .41* | −.26* | .01 | −.34* |
2. Zoo trip inefficiency | .25* | (.68) | −.41* | −.14 | −.26* |
3. WCST # Categories | −.19* | −.34* | (NA) | .23* | .33* |
4. Letter fluency | .01 | −.10 | .21* | (.86) | .59* |
5. Category fluency | −.24* | −.18* | .31* | .51* | (.88) |
Note: Values in parentheses are estimated reliabilities. Correlations below the diagonal are raw correlations and those above the diagonal are adjusted for reliability with the formula (rXY′= rXY)/√([rXX * rYY]). Because no estimate of reliability was available for the WCST variable the adjusted correlations assume that the reliability for that variable is 1.0, and thus they are underestimates of the reliability-adjusted correlations.
