†
Average weekly pain and fatigue were rated on a scale of 0 – 4 for Sample 1 and on a scale of 0 – 10 in Sample 2 and these values are presented above. The independent t-tests between samples for pain and fatigue were performed using the z scored variables (n = 54).
‡
Significantly different from Sample 2 at p < .05.
