At T2 there were significant differences between groups on the MIHT perception subscale (t = -3.71, df = 11, p = .002; power = 1.00 [high power]; see Table 6 and Table 7). The T2 difference on the perception subscale likely occurred because the SHB group lowered their scores on that subscale and had less preoccupation with bodily sensations. Again, the lack of other significant differences may be due to the small sample size and lack of statistical power. The effect sizes were large for the SHAI (d = 1.09), MIHT cognition (d = 1.14), perception (d = 1.72), and affect subscales (d = 0.90); medium for the MIHT behaviour subscale (d = 0.74) and CES-D (d = 0.68); and small for the SF-36 PCS (d = 0.23) and MCS (d = 0.21). At T3 there were significant differences between the WLC and SHB groups on the SHAI (t = 4.30, df = 7, p = .004; power = .78 [low power]) and MIHT cognition (t = - 2.58, df = 12, p = .024; power = .78 [low power]), perception (t = -4.46, df = 10, p = .001; power = 1.00 [high power]), and affect subscales (t = -1.98, df = 12, p = .036; power = .47 [low power]; see Table 7 and Table 8). The differences on the SHAI and MIHT are understandable given the improvements the SHB group experienced on these measures. The most robust change was on the MIHT perception subscale which means the main difference between receiving and not receiving treatment was a reduction in preoccupation with bodily sensations. Due to the small sample size, there was inadequate power behind the other statistically significant results. It is very likely that with a larger 62
