CCHS interviews were subsequently conducted between January and December 2018 by computer-assisted telephone interviewing (75%) and computer-assisted face-to-face interviews (25%). The interview was available in both English and French with
interpretative services available for several other languages. However, the CCHS containing the Gambling Module was only fielded for a 6-month period (July to December 2018) and only in the provinces (no territories). A total of 45,636 households were eligible. Of these, 30,995 households agreed to participate, and CCHS surveys were ultimately obtained from 26,648 individuals (58.4% overall response rate). Because the Gambling Module was restricted to ages 15 and older and did not permit proxy respondents, a smaller number of individuals
were actually eligible (25,639), with 24,982 CCHS Gambling Module surveys ultimately obtained, with 23,952 of these being from adults (18+).

Journal of Gambling Issues, 28, 1-24. http://dx.doi.org/10.4309/jgi.2013.28.31979Self-report questionnaire consisting of about 300 items adminstered to each participant; Data were collected by GFK Eurisko between June 2010 (pilot) and July 2010 (study). A quota sample, balanced by geographical area (four areas), city size (five groups), and age by gender (12 groups), was used. Participants were contacted by an interviewer, and then invited to fill out a questionnaire. The questionnaire was individually administered to participants at their own house. Individuals received a reimbursement of about 20 euros for their participation. About 5% of the persons who were first contacted later declined to participate and were replaced by other participants with homogeneous characteristics.
self-report questionnaireWeights have been defined by considering level of education (four levels), occupation (nine categories), penetration/diffusion into the Italian population of the games considered in the survey (12 categories), geographical area (four zones) by size of city (five levels), and gender (two categories) by age (six categories) (note: frequencies used for the weighting procedure are available from the first author).
SOGS [Italian Version]; CPGI [Italian Translation]SOGS: probably pathological = 2.05%; CPGI: problem gambling = 2.17%Results preliminarily demonstrated that the psychometric properties of the SOGS and PGSI can be confirmed in the Italian population; a social desirability scale was included in the questionnaire.http://dx.doi.org/10.4309/jgi.2013.28.3

Approximately 60% of those surveyed lived in flats or houses made of brick, as opposed to living in shacks or other informal kinds of dwelling. [This survey differs from previous S. African studies as it includes a lower proportion of relatively affluent South Africans]. “The most notable difference in the way the data was collected was that the 2005 sample was deliberately skewed towards the ‘developed or first world’ sector of the South African economy rather than towards it ‘developing or third world’ sector.”face-to-face residential interviewany participation in gamblingGamblers Anonymous 20 Questions; CPGI2,075 People per EGM in 200852.1%CPGI: 8% (3-7); 3% (8+); 11% combined6.4%11.0 *.58 = 6.4%younger age; depression; substance abuseRanking games based on proportions of participants at high risk for problem gambling, we obtain, from highest to lowest: Dice games for money, Card games for money, Roulette, Fafi / iChina tied with Sports betting, Horse racing and other animal events tied with Electronic gaming machines, Lucky draws, Scratch cards tied with Slot machines tied with Bingo, Lottery / Lotto; casino gambling is negatively associated with problem gambling.Survey administered by Ipsos-Mori.http://www.responsiblegambling.co.za/media/user/documents/Summary%20of%20basic%20data%20on%20from%20the%20National%20Urban%20Prevalence%20Study%20of%20Gambling%20Behaviour%20-%20March%202010.pdfhttp://www.responsiblegambling.co.za/media/user/documents/NRGP%20Comparative%20Report%20-%20June%202009.pdf

1,736 (reported as 1,749 in NORC report)Three-stage sample design; First, a set of primary sampling units (counties, large cities, and boroughs) were selected at random to represent all of the household dwellings in the country. Approximately 3,250 households were then selected randomly within these primary sampling units (including an oversample of households in 12 of the largest U.S. cities). Random selection of individual within households, with a two-to-one oversample of males. This initial household contact was the “screening” stage, completed in approximately 2,680 households, or 82.5% of those sampled. Survey carried out by the Institute for Social Research, University of Michigan.face-to-face residential interviews75.5%gender (adjusting for oversampling), geography, household type, income, race, education, and occupation“Clinical analysis” based on a) the similarity of the respondent answered 18 questions relative to how 274 known compulsive gamblers answered the same questions; b) observations recorded by the interviewer at the end of each interview; c) betting patterns reported by the respondent.Most casino style gambling expansion occurred after 1989 (after 1988

61% (Lifetime = 68%)As a result of this clinical examination, it was estimated that 0.77% of the national sample could be classified as "probable" compulsive gamblers, with another 2.33% as "potential" compulsive gamblers.MalesThe 1975 survey included a supplementary adult survey of 296 persons in three counties in the State of Nevada.
