Global prevalence of help-seeking for problem gambling: A systematic review and meta-analysis

Abstract

Background and aims: Multiple studies have examined barriers and facilitators to help-seeking, but the prevalence of help-seeking for problem gambling (PG) is not well established. We aimed to estimate the international prevalence of help-seeking for PG among the general population and among subgroups of people at risk for PG (i.e. low-risk, moderate-risk and PG).

Methods: Systematic search of grey literature (through gambling repositories, gambling research institutes and Google) and peer-reviewed literature (through ProQuest, PsycINFO, PubMed and Scopus) for gambling prevalence studies that reported on help-seeking for PG. This review adhered to the Preferred Reporting Items for Systematic Review and Meta-Analyses. Studies used representative sampling methods to determine the prevalence of gambling participation and data collection 2010 onward. Twenty-four studies met the inclusion criteria. The main outcome was population prevalence of help-seeking for PG. Help-seeking was defined as any intentional action to change gambling behaviours, including professional services (inclusive of in-person or distance help), non-professional help (e.g. from family and friends) and self-help. Subgroup analyses were conducted to explain variability in help-seeking prevalence estimates.

Results: Measurement of help-seeking was inconsistent across included studies and, overall, there was high risk of bias. We estimated a general population help-seeking prevalence for PG of 0.23% (95% CI, 0.16-0.33). Prevalence estimates were significantly higher in studies assessing lifetime (0.50%; 95% CI, 0.35-0.71) compared with current help-seeking (0.14%; 95% CI, 0.10-0.20, P < 0.001), but there was no evidence of difference in prevalence estimates by gambling participation, region, type of help-seeking, or year of data collection. Compared with people with low-risk gambling (0.27%; 95% CI, 0.07%-1.04%), prevalence estimates were significantly higher in those with moderate-risk (3.73%; 95% CI, 2.07%-6.63%) and problem gambling (20.63%; 95% CI, 12.89%-31.35%, P < 0.001).

Conclusions: One in 25 moderate-risk gamblers and 1 in 5 people with problem gambling have sought help for problems related to their gambling.
