British Gambling Prevalence Survey 2007 secondary analysis: understanding non-response
This project was undertaken by NatCen and considered whether
participant non-response may have had an effect on the results of
the
British Gambling Prevalence Survey 2007. Among other
things it considered the effect of non-response to the problem
gambling questions on the survey estimates.

survey 2007 - October 2008
Key findings
Overall, the findings reported in the BGPS 2007 were robust
against potential non-response biases.
Infrequent gamblers were less likely to answer the problem
gambling screen than frequent gamblers. This meant that the
prevalence of problem gambling in some population sub-groups was
marginally lower than previously reported. However, this had no
impact at the overall population level, meaning that the level of
problem gamblers remained at 0.6%, the same as stated in the BGPS
2007 report.
The report made a number of recommendations for reducing
non-response biases in future prevalence surveys. These included
considering the relevance of questions to respondents in order to
encourage them to complete the questionnaire and continued
assessment of future BGPS surveys to measure whether the
introduction of an additional weight to account for non-response to
the problem gambling screens is necessary.
