Another possibility is the presence of sex differences in the self-report of OI; for example, a previous study showed that symptoms of vertigo, dizziness or unsteadiness may be more related to psychological factors in men [ 60].
The results may also be influenced by GP recall and positive responding (particularly in regard to provision of a written asthma action plan by the intervention group); however, no statistically significant differences were found in the self reported provision of a written asthma action plan.
While there was a significant difference in those who were aware of the study between zones, there was no significant difference in the self-report of "teeth and gums symptoms" (a variable used to determine over or under reporting) between zones.
There was no difference in the self-report ratings of the two groups concerning the extent to which they adhered to the contract (M = 80.0 in the low personal standards condition vs. M = 78.7 in the high personal standards condition; SD = 15.1 and 8.8, respectively; t (39 ) =. 33, p >. 05 ).
Mann-Whitney tests were used to test for sex differences in the self-reported temperature and unpleasantness ratings at each of the pain sensory levels, as well as difference in the amount of change in those self-reports between pain levels.
No differences were observed in the self-report pain ratings of children between groups (F<1).
Second, this study was conducted with science and biology teachers without focusing on the differences in their responses to the self-report instruments.
While there was a tendency to over-estimate the number of hospital nights in the self-report data, the differences were not large enough to be statistically significant.
A higher proportion of patients in the exercise group than in the control group reported recovery (41.9% v 35.0% at 3 months and 62.1% v 50.8% at 12 months), although the differences in self reported recovery between the two groups were not statistically significant.
Comparing correlation coefficients revealed no significant differences in correlations between any of the self-report measures and HbA1c levels (all P > 0.17).
In Scotland, social class differences in self reported health between the highest and lowest were the most acute in Britain for both men and women [ 7].
