GambleAware has released research that looks at the differences in gambling surveys and how they can skew the results.
The study aims at improving gambling harm research. It also focuses on better understanding the “true demand” for gambling harm treatment and support.
It uses eight different surveys to demonstrate how various methodological factors in each can lead to different outcomes.
The most important finding was that surveys that only use online self-completion responses produce higher estimates of gambling harm than surveys that include paper completed responses as part of a face-to-face interview.
GambleAware says this is due to selection bias since online surveys are suitable for those comfortable with technologies.
