The Following Result Is Reported for a Study by Kain

The following result is reported for a study by Kain et al. (2008) on the number of parents who should be let into the operating room. In respect of parental anxiety along two time points (holding area and separation from children) a two-way ANOVA with repeated measures evaluation was performed with the following result in relation to group × time interaction: F(1,95) = 7.78, p = 0.006. In the one-parent group versus the parents in the two-parent group the result is shown as 48.6 + 13.1 vs. 39.7 +11.5, p < 0.02. (Source: Kain, Z. N., MacLaren, J., Weinberg, J., Huszti, H., Anderson, C., & Mayes, L. (2009) . How many parents should we let into the operating room? Paediatric Anaesthesia, 19(3) , 244-249.)
