Does the lived experience of gambling accord with quantitative self-report scores of gambling-related harm?

A broad quantitative literature has explored the extent and distribution of gambling-related harm. However, any quantitative measure involves a number of statistical decisions around item selection and weighting that may affect its ability to provide an accurate summary of a gambler's lived experience. This may especially be an issue with a condition as varied and multifaceted as gambling-related harm. The present research therefore used qualitative methods to validate the categorization of gamblers into four levels of harm via the Gambling Harms Scale (10-items) (GHS-10) through an analysis of 30 semi-structured interviews with gamblers. Results showed that unharmed gamblers saw gambling as just another leisure activity, which relieved stress and brought them closer to other people. Low harm gamblers were similar but could experience emotional stresses over their level of gambling expenditure. Just under half of all moderate harm gamblers experienced occasional severe financial impacts and emotional stresses from their gambling. Finally, all high harm gamblers experienced chronic financial impacts and emotional stresses, which spilled over into relationship problems for three quarters of this group, and negative impacts on health or work/study for around half of this group. These results showed that the severity of participants' lived experience of gambling increased with their GHS-10 score, providing a qualitative validation for this quantitative self-report measure. This qualitative validation for a quantitative scale is argued to be a promising avenue for future gambling research.
