y T3 (see Table 3). Scores on the SHAI were the only SHB scores that were outside the
healthy normative range at T1, therefore, the other study measures could not be assessed
for clinical significance. Based on the SHAI results, treatment helped participants to
decrease their cognitive (disease preoccupation, hypervigillance to bodily sensations,
somatosensory amplification), somatic (anxiety-related bodily sensations), behavioural
(reassurance seeking and bodily checking), and affective symptoms (excessive worry
about health) of health anxiety. However, when compared to the Salkovskis et al., (2002)
healthy normative sample, the participants‘ health anxiety levels were still above the
mean and they were not fully recovered from their excessive health anxiety. Above
average scores on the SHAI may have remained because participants‘ physical symptoms
had not disappeared and they were still anxious about that or the possibility of becoming
ill in the future. The beliefs about illness risks and indicators of disease may take longer
to change and the physical symptoms of anxiety may remain until these beliefs are
successfully altered.
SHB scores on the MIHT were compared to the healthy normative sample means
reported in the Longley et al., (2005) validation study (Table 3). MIHT behavioural
subscale scores were above average at T1 and by T3 they were approximately average (t
= 4.03, df = 9, p = .002; power = .94 [high power]; see Table 3). Perception subscale
scores were elevated at T1 and were also reduced by T3 (t = 4.19, df = 9, p = .001; power
= .96 [high power]). On the cognitive subscale, scores at T1 were above average but there
