Proxy and self-report correlation was higher for children with health problems than for healthy children.
Recent reviews have shown that self report has moderate correlation with electronic monitoring [ 8, 9], although self reported adherence levels are higher than adherence levels derived from MEMS [ 9].
The assessment of correlations between the domains of teen self report revealed moderate to large correlations between PF and SF (ρ = .44) domains (Table 4).
Though clinical data regarding the periodontal disease status of the participants might have strengthened our findings, previous research has also shown a good correlation between self report and clinical evaluation of periodontal disease.
This can be compared with correlations of self report versus gold standard measurements that are usually in the range of r = 0.0-0.2 0.0-0.2
Only significant correlations between the clinical measures and sleep variables were observed with self report methods of assessment: the corresponding correlations with the actigraph derived variables were low and non-significant, again emphasising the importance of utilising both self-report and objective measurement to establish accurate relationships between sleep and other health variables.
For child self-reports, the correlation coefficients of 17 items' scores (total 23 items) with the scores of dimensions they belong to were above 0.5, with the highest 0.759; the other 6 items' correlation coefficients were below 0.5, with the lowest 0.280.
With the exception of the self reported prosocial subscale correlations for both informants on all subjects the intra-class correlations were all above 0.70.
Self reported weight was highly correlated (correlation coefficient 0.96) with measured weight in a previous validation study in 184 participants.
We found a modest correlation between self reported and validated number of calls, but a weaker correlation between self reported and validated duration of calls.
Workload scores as assessed by the observer were correlated with anaesthetists' self reported workload scores with Spearman's correlation coefficients.
