* Significance level is set at 5%.
† Levels of scale success:
2: Item-scale correlation is significantly higher for hypothesised scale than for competing scale.
1: Item-scale correlation is higher for hypothesised scale than for competing scale, but not significantly.
-1: Item-scale correlation is lower for hypothesised scale than for competing scale, but not significantly.
-2: Item-scale correlation is significantly lower for hypothesised scale than for competing scale.
