The findings from Swelogs (Swedish longitudinal gambling study) first round of data collection were published in 2010. The findings showed that 2 % of the Swedish population were problem gamblers. This figure has been used by various stakeholders to claim that 98 % of the Swedish population are happy gamblers. However, it is not really that simple.
Swelogs, the Swedish longitudinal gambling study, is a Swedish population study of health and gambling being conducted over seven years, between 2008 and 2015. The study aims to build an evidence base to develop effective preventive measures against the harmful effects of excessive gambling. The roughly 8,000 randomly selected respondents between the ages of 16 and 84 who took part in the baseline study will be contacted at least three more times during the course of the study. Data used in this fact sheet is from 2008/2009. The degree of gambling problems was assessed based on the measurement instrument Problem Gambling Severity Index (PGSI).
