The anxiety and depression scores from the HADS were negatively skewed and were square root transformed to improve their distribution. All personality measures showed distributions close to normality. Descriptive statistics for the NEO-FFI, IPIP and HADS measures appear in Table 1. Consistent with prior evidence, sex differences (women scoring higher) were observed for HADS anxiety (p < .001), NEO and IPIP neuroticism (p < .01) and agreeableness (p < .0001). NEO openness to experience (p < .0001) and extraversion (p < .05) scores were also higher in women but their corresponding IPIP factors showed no sex differences. Age effects were observed for NEO and IPIP conscientiousness (p < .05), such that lower scores tended to be associated with older age. However, the age range in the sample is very small.
