GSGB: Different survey, same story? (written by Professor Heather Wardle)
Detail from 2 academic reports used to assess whether the GSGB and HSE tell a coherent story about how gambling is distributed across groups, products, and contexts.
Report 2: Exploring the relationship between PGSI scores and health and wellbeing
In a second report Tipping et al (2025) (opens in new tab) examined the relationship between mental health and wellbeing and Problem Gambling Severity Index (PGSI) scores, with a particular focus on PGSI scores between 0 and 7. While the primary analysis drew on combined English and Scottish health survey data, supplementary analysis using Gambling Survey for Great Britain (GSGB) data was also presented, providing an opportunity to assess the consistency of findings across the 2 studies.
Using the health surveys data, Tipping found that lower wellbeing - measured using the Warwick-Edinburgh Mental Wellbeing Scale (opens in new tab) - was associated with increasing PGSI scores. The relationship followed an r-shaped pattern, indicating that the association with low wellbeing strengthened most sharply at the lower end of the PGSI scale, particularly between scores of 1 and 3. This analysis was replicated using GSGB data (see Tipping et al, supplementary material (opens in new tab)), which demonstrated the same pattern: lower wellbeing was associated with higher PGSI scores, and the relationship retained its r-shaped form.
