The secondary outcome of this study, to ascertain the effect of a chair and VDU height adjustment on comfort level whilst sitting at work, shows that the subject became more uncomfortable after the intervention phase (Figure 6). During the exit interview, the subject verbally reported to the researcher that she was comfortable at the workstation after the intervention. The subject indicated that the anchor labels ‘very comfortable’ and ‘extremely uncomfortable’ (Figure 1) may have caused confusion, with ‘greater comfort’ assumed to involve a mark further to the right on the VADS. Mekhora et al. (2000:367–379) reported using a VADS with anchors of ‘discomfort’ throughout (‘no discomfort’ vs ‘extreme discomfort’); however, when the VADS gure in the article is consulted the anchors are marked ‘no pain’ and ‘extreme pain’. Gerr et al. (2005:478–487) used a VADS in which subjects were asked to rate the ‘worst discomfort such as pain, aching, burning, numbness or tingling during the previous week’. Comfort is arguably a less often investigated construct compared to outcomes such as pain. Further research may be required to establish standardised methods to measure comfort. This will facilitate comparison between studies in the future.
