Assessment of Gambling Survey 2021 Faces Scientific Backlash, Citing Flaws in Research Methodology
In a significant development, an independent scientific review commissioned by industry representatives has been conducted on the Gaming Survey 2021, a study aimed at estimating the number of people with risky gambling behaviour in Germany. The review, led by Katharina Schüller and Prof. Dr. Ralf Münnich, has identified a series of potential methodological flaws that may undermine the data quality of the survey.
The reviewers are now available for a public scientific discourse with the authors of the Gaming Survey 2021, offering an opportunity for open dialogue and potential improvements in future studies.
The Gaming Survey 2021, conducted by ISD Hamburg and the University of Bremen, has raised some eyebrows in the industry. The Federal Institute for Public Health (BIG) estimated the same group to be only 0.73% in 2019, a figure that was puzzling for many.
Schüller and Prof. Dr. Münnich, in their 140-page review, have outlined the perceived shortcomings of the Gaming Survey 2021. The review is freely accessible, providing valuable insights into the potential methodological flaws that may have been present.
Common methodological issues often found in gaming-related studies include selection bias, study design limitations, confounding factors, insufficient blinding, data collection issues, attrition and missing data, and lack of transparency and rigor. It is likely that the independent scientific review of the Gaming Survey 2021 found comparable shortcomings, such as sample bias, insufficient controls, lack of transparency, or data quality issues. However, the exact details of the flaws specific to the Gaming Survey 2021 are not present in the provided search results.
The review by Schüller and Prof. Dr. Münnich is seen as progress by industry representatives, as it paves the way for better methodologically structured future surveys on gambling prevalence and problematic gambling. Mathias Dahms, president of the German Sports Betting Association, has called for improving the state of research in the field of gambling.
Whether a new database will soon be available that allows for a more reliable assessment and observation over time of the gambling behaviour of the German population remains to be seen. The findings of the independent review and the subsequent dialogue between the reviewers and the authors of the Gaming Survey 2021 are expected to contribute significantly to the advancement of research in this field.
- The review by Schüller and Prof. Dr. Münnich has highlighted the need for improvement in the methodology of online casinos surveys in Germany.
- The gaming industry is keen on fostering responsible gambling trends, and Mathias Dahms, president of the German Sports Betting Association, supports the advancement of research in this field.
- The Gaming Survey 2021, conducted by ISD Hamburg and the University of Bremen, raised concerns due to the marked discrepancy with previous estimations by the Federal Institute for Public Health.
- Casino-personalities, educators, and self-development advocates are eager to see the outcome of the public scientific discourse between the reviewers and the authors of the Gaming Survey 2021.
- The reviewers' findings shed light on potential issues in casino-and-gambling studies, such as selection bias, lack of transparency, and data quality problems, which may also affect the quality of data in online casinos in Germany.
- Businesses in the online casinos, casino-games, lotteries, and gambling industry closely follow gambling-trends and the dialogue between the reviewers and the Gaming Survey 2021 authors, as it could potentially impact the career-development and growth of their businesses.
