Prevalence of gambling behaviours
The 2021 pilot survey reported a higher prevalence of gambling relative to the Health Survey for England (HSE) 2018. There appeared to be a response bias with the pilot study being more attractive to those who gambled, overestimating the prevalence within the population. This part of the analysis looked to establish whether there were significant differences between the two experimental conditions which could impact key survey statistics on gambling participation in the last 12 months.
There was no statistically significant difference between C1 (up to two adults) and C2 (up to four adults) households in the three last 12 months participation measures considered (any gambling, any gambling excluding the national lottery only; any online gambling) ('Figure 4: Gambling participation in the last 12 months, by experimental condition' as follows).
Figure 4: Gambling participation in the last 12 months, by experimental condition
| Gambling participation in the last 12 months | Experimental condition C1 (up to two adults) (percentage) |
Experimental condition C2 (up to four adults) (percentage) |
|---|---|---|
| Any gambling | 62.1% | 62.0% |
| Any gambling other than the National Lottery | 47.4% | 47.9% |
| Any online gambling other than the National Lottery | 13.7% | 15.2% |

Note: Responses in the chart do not add up to 100 percent as they represent NET percentages of those participating in a number of different activities.
'Figure 5: Gambling activities in the last 12 months by experimental condition and adherence to participation-selection instructions' as follows, expanded this analysis to include adherence (such as whether adherence to participant-selection instructions further impacts gambling participation rates). Those from non-adherent households (irrespective of experimental condition) had higher gambling participation rates than those from adherent households but the differences were not statistically significant.

| Gambling participation in the last 12 months | Experimental condition C1 (up to two adults): adherent (percentage) |
Experimental condition C2 (up to four adults): adherent (percentage) |
Experimental condition C1 (up to two adults): non-adherent (percentage) |
Experimental condition C2 (up to four adults): non-adherent (percentage) |
|---|---|---|---|---|
| Any gambling | 62.4% | 62.0% | 66.5% | 63.8% |
| Any gambling other than the National Lottery | 47.4% | 48.0% | 51.7% | 50.5% |
| Any online gambling other than the National Lottery | 13.7% | 14.0% | 15.7% | 19.1% |
