Another method to reduce anxiety has been explored by Brewer et al. (2006) who looked at the use of a child life specialist supporting a child and parent during an admission for same day surgery, to determine if children who were prepared for same day surgery using this approach exhibited less anxiety than those who were not prepared. Child life specialists are experts in child development and work with children within healthcare facilities assisting them to alleviate any anxiety and stress caused by their admission to hospital. Brewer et al. (2006) implemented a double blind, alternate assignment approach to a sample group of children attending for day surgery (n = 80 intervention, n = 62 control). Following parental permission, the child's anxiety was measured with an instrument (“Child Drawing: Hospital”) specifically designed for this study to assess anxiety from a child's point of view before and after surgery. This tool was validated and deemed reliable by the authors. They demonstrated that the intervention group showed reduced levels of anxiety, but this was not statistically significant, whilst the control group displayed a significant increase in anxiety (Brewer et al., 2006).
