The major objectives of this track are to provide general population estimates of the prevalence and incidence of problem and at\u2010risk gambling and enable comparisons with the first Swedish national study on gambling and problem gambling (Swegs) conducted in 1997\/1998. The overall study (Swelogs) comprises three tracks of data collection; one epidemiological, one in\u2010depth and one follow\u2010up. It is expected to provide information that will inform the development of evidence\u2010based methods and strategies to prevent the development of gambling problems. This paper gives an overview of the design of the epidemiological track, especially of its two first waves. The baseline wave, performed between October 2008 and August 2009, included 8165 subjects, of whom 6021 were re\u2010assessed one year later. A stratified random sampling procedure was applied. Computer\u2010supported telephone interviews were used as the primary method. Postal questionnaires were used to follow\u2010up those not reached by telephone. The response rate was 55% in the first wave and 74% in the second. The interview and questionnaire data are supplemented by register data. \u00a9 2014 The Authors. <jats:italic>International Journal of Methods in Psychiatric Research<\/jats:italic> published by John Wiley &amp; Sons Ltd.<\/jats:p>","DOI":"10.1002\/mpr.1449","type":"journal-article","created":{"date-parts":[[2014,6,18]],"date-time":"2014-06-18T14:28:29Z","timestamp":1403101709000},"page":"372-386","source":"Crossref","is-referenced-by-count":45,"title":["The Swedish Longitudinal Gambling Study (Swelogs): design and methods of the epidemiological (EP\u2010) track"],"prefix":"10.1002","volume":"23","author":[{"given":"Ulla","family":"Romild","sequence":"first","affiliation":[{"name":"Public Health Agency of Sweden  \u00d6stersund Sweden"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rachel","family":"Volberg","sequence":"additional","affiliation":[{"name":"Gemini Research Ltd  Northampton MA USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Max","family":"Abbott","sequence":"additional","affiliation":[{"name":"Auckland University of Technology  Auckland New Zealand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2014,6,18]]},"reference":[{"key":"e_1_2_5_2_1","doi-asserted-by":"publisher","DOI":"10.1080\/14459790701261714"},{"key":"e_1_2_5_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF01539171"},{"key":"e_1_2_5_4_1","volume-title":"A Review of Research on Aspects of Problem Gambling","author":"Abbott M.W.","year":"2004"},{"key":"e_1_2_5_5_1","volume-title":"The Canadian Problem Gambling Index: Final Report","author":"Ferris J.","year":"2001"},{"key":"e_1_2_5_6_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0033291702006700"},{"key":"e_1_2_5_7_1","doi-asserted-by":"publisher","DOI":"10.1093\/aje\/152.11.1039"},{"key":"e_1_2_5_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/mpr.317"},{"key":"e_1_2_5_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1530-0277.2002.tb02534.x"},{"key":"e_1_2_5_10_1","volume-title":"Gambling and Problem Gambling in Sweden","author":"R\u00f6nnberg S.","year":"1999"},{"key":"e_1_2_5_11_1","volume-title":"A Theoretical Foundation for Gambling Prevalence and Intervention Research.
