Superscript lower case letters designate significant (all ps < .05 adjusted for number of comparisons) differences between means across the five dimensions of health found in follow-up analyses as a result of significant main and interaction effects from within-subjects ANOVA. All t-tests are independent sample t-tests comparing across groups (i.e. male vs. female persons with FXS and 5–10 year olds vs. 11–17 year olds) for each dimension of health
