^aTable entries are means with standard deviations in parentheses; scale scores have been transformed to range from 0 to 100 with high scores indicating better health

^bMean differences are entered as child-reported scores minus parent-reported scores for each measure with 95% confidence intervals for mean differences in parentheses; statistical significance is based on F-statistic using one-way ANOVA, adjusting for parental age, education, race, number of the child’s siblings, extent of sibling illness, child’s age, and number of the child’s health problems

^cEffect size (mean difference expressed as a proportion of the pooled standard deviation)

^dIntra-class correlation coefficients for agreement between child and parents scores on each measure (estimated using one-way random effects models and method of moments); scores < .40 are considered poor agreement³⁹

^ePain was transformed such that higher score indicates less pain
