The impact of nonresponse on estimates of mental health problems was examined in a prospective teacher screen in a community
survey of 9,155 7–9 year olds. For 6,611 of the children, parents consented to participation in the actual study (Responders),
while for 2,544 children parental consent was not obtained (Nonresponders). The teacher screen involved assessment of a broad
set of symptoms of mental health problems and functional impairment. Calculations of non-response coefficients, a function
of effect sizes and non-response proportion, revealed only ignorable nonresponse bias for both mean scores and correlations.
However, the results from binary logistic regressions revealed that children ascribed signs of mental health problems by their
teachers were less likely to participate. This was most frequent among children with only moderate symptoms. However, it also
involved children with high symptom scores related to inattention, hyperactivity, emotions and peer relationship problems.
These findings suggest that measures based on effect size can underestimate the magnitude of non-response bias and that a
logistic regression approach may be more appropriate for studies geared at estimating prevalence of mental health problems
in children.
The study was financially supported by the Norwegian Research Council, The Norwegian Directorate for Health and Social Affairs,
Western Norwegian Regional Health Authority, the L. Meltzer legacy for the University of Bergen, and the City of Bergen. 相似文献
