Data analysis
Statistical analyses were carried out using the Statistical
Package for Social Science, version 15.0 for windows (SPSS,
Chicago, IL, USA). Sum scores of the 10 RH items were first
calculated for each participant. The fact that only a RH sum
score over 20 may imply an over-rating (Day et al. 1995), and
the RH score range in this study was between 0 and 19,
suggests that measurements had reflected true side effects
without overestimation. Therefore, data collected from all
participants were included in the subsequent analysis.
