Significant results were based on dichotomizing anxiety into high scores (41 SD above mean) versus all others; a similar approach (upper 25th percentile) was necessitated
in another study (Van den Bergh, Mennes et al., 2005). Descriptive values are not provided in the former but examination of those in the latter report reveals substantially higher mean STAI anxiety values than comparable ones in the current study providing potential support for curvilinear associations.
