Table 1. Pearson correlates between positive affect scores, negative affect scores and hamilton anxiety and depression scale scores.

Variables	1	2	3	4	5

Legend. Correlations between 1 and 2 were performed over N = 63. All others were performed over N = 59.

NA = Negative affect, PA = Positive affect, HADS = Hamilton Anxiety and Depression Scale.

NA and PA represent mean scores over all subjects for one measurement period.

HADS anxiety, HADS depression, and HADS total represent subject scores for one measurement period.
