*Correlations between items and hypothesized scale, corrected for overlap. †Correlations between items and scales other than hypothesized scale. ‡Percentage of correlations between items and hypothesized scale that are < or = 0.40. §Percentage of correlations between items and hypothesized scale that are greater than correlations between items and other scales, without regard to significance (standard error of correlation = 0.08).
