1 Pearson correlations between items and hypothesized scale (corrected for overlap).
2 Number of item-scale correlations that meet minimum standard for convergent validity (≤ 0.40).
3 Pearson correlations between items and other scales.
4 Correlations higher between items and other scales in comparison with hypothesized scale (by two standard errors or more; ≤ 0.16)
