Measuring adolescents' HRQoL via self reports and parent proxy reports: an evaluation of the psychometric properties of both versions of the KINDL-R instrument

Table 8 Impact of socio-economic status on HRQoL children self reports and parents proxy report

Standard errors (SE) for the means: low SES = 0.24 – 0.45 (self) vs. 0.17 – 0.28 (parent); medium SES = 0.18 – 0.31 (self) vs. 0.17 – 0.30 (parent); high SES = 0.23 – 0.39 (self) vs. 0.23 – 0.39 (parent); 95% confidence intervals = mean +/- 1.96*SE)
^aSocioeconomic status classification according to the Winkler Index [27].
^b"d"-effect size for comparison between low and high socioeconomic status (0.2 = small; 0.5 = medium; 0.8 = large effect)
* statistical significant (p < .05) F-value in ANOVA; ** statistical significant (p < 0.01) F-value in ANOVA
No statistically significant interaction was observed for mode * socio-economic status
All statistical interactions between mode (parent versus self) and CSHCN were statistically significant
All statistical interactions between mode (parent versus self) and weight status were statistically non-significant except for KINDL Psych (p = 0.011; "f" = 0.04 [marginal effect]).
