*p < .05, **p < .01, ***p < .001 based on Tukey post-hoc analysis. Effect sizes are designated as small (.20), medium (.50), and large (.80). Effect sizes represent the magnitude in the differences between the Fibromyalgia and Healthy Children samples only. α = Cronbach internal consistency reliability coefficient alpha.
