census. A supplemental Onl<strong>in</strong>e General Population sample was also collected via email<br />
solicitation to Alberta onl<strong>in</strong>e panellists 4 who were members <strong>of</strong> NetPanel. The purpose <strong>of</strong><br />
collect<strong>in</strong>g an onl<strong>in</strong>e sample was to <strong>in</strong>vestigate whether prevalence rates obta<strong>in</strong>ed with this<br />
method would approximate the rates obta<strong>in</strong>ed with telephone surveys and potentially<br />
supplement or replace telephone surveys (<strong>in</strong> light <strong>of</strong> their steadily decl<strong>in</strong><strong>in</strong>g response rates).<br />
The size <strong>of</strong> the onl<strong>in</strong>e sample was 2,019 <strong>in</strong> the summer <strong>of</strong> 2008 and 1,006 <strong>in</strong> the summer <strong>of</strong><br />
2009. The actual surveys themselves as well as comprehensive details about the methodology<br />
used to conduct them are conta<strong>in</strong>ed <strong>in</strong> Appendix A.<br />
Changes <strong>in</strong> population attitudes, behaviour, and problem <strong>gambl<strong>in</strong>g</strong> prevalence rates over time<br />
also provide an <strong>in</strong>direct way <strong>of</strong> gaug<strong>in</strong>g the impact <strong>of</strong> the <strong>in</strong>troduction/expansion <strong>of</strong> the various<br />
forms <strong>of</strong> <strong>gambl<strong>in</strong>g</strong>. Fortunately there have been several different population surveys <strong>of</strong><br />
<strong>gambl<strong>in</strong>g</strong> beg<strong>in</strong>n<strong>in</strong>g <strong>in</strong> 1992 that permit this type <strong>of</strong> analysis (see Appendix B).<br />
In addition to General Population surveys <strong>of</strong> adult Albertans, we also conducted ‘Targeted<br />
Population Surveys’ where we exam<strong>in</strong>ed the changes <strong>in</strong> attitudes, <strong>gambl<strong>in</strong>g</strong> behaviour, and<br />
problem <strong>gambl<strong>in</strong>g</strong> <strong>in</strong> the summer <strong>of</strong> 2008 versus 2009 <strong>in</strong> 4 geographic areas that did not have<br />
cas<strong>in</strong>os prior to their <strong>in</strong>troduction <strong>in</strong> late 2007/early 2008 (‘New Cas<strong>in</strong>o Areas’): Cold Lake area;<br />
Whitecourt area; Camrose area; Morley area. To control for changes that might have occurred<br />
simply as a function <strong>of</strong> time, we compared changes <strong>in</strong> the New Cas<strong>in</strong>o Areas to changes<br />
observed <strong>in</strong> 5 geographic areas with well-established cas<strong>in</strong>os (‘Established Cas<strong>in</strong>o Areas’): Fort<br />
McMurray area; Grande Prairie area; Red Deer area; Medic<strong>in</strong>e Hat area; <strong>Lethbridge</strong> area. (Note<br />
also that these 5 control regions represent ‘rural’ areas, similar to the 4 New Cas<strong>in</strong>o areas). The<br />
4 In recent years Survey <strong>Research</strong> firms have created ‘onl<strong>in</strong>e panels’ composed <strong>of</strong> hundreds <strong>of</strong> thousands <strong>of</strong><br />
<strong>in</strong>dividuals who have agreed to receive onl<strong>in</strong>e solicitations to participate <strong>in</strong> various onl<strong>in</strong>e surveys <strong>in</strong> return for<br />
compensation (most <strong>of</strong>ten, a collection <strong>of</strong> ‘po<strong>in</strong>ts’ that have some cash value) (Göritz, 2007; Göritz et al., 2002).<br />
When an <strong>in</strong>dividual jo<strong>in</strong>s one <strong>of</strong> these panels, <strong>in</strong>formation is collected concern<strong>in</strong>g his/her demographics.<br />
Subsequently, when a group is needed for a particular survey (e.g., ‘representative sample <strong>of</strong> Alberta adults’), the<br />
survey is only sent out to this selected subsample. Onl<strong>in</strong>e panels are now commonly used <strong>in</strong> market research, but<br />
have rarely been used <strong>in</strong> academic studies. The advantages <strong>of</strong> onl<strong>in</strong>e panel surveys are that a) the validity <strong>of</strong><br />
answers to ‘sensitive questions’ (e.g., <strong>gambl<strong>in</strong>g</strong>) tends to be higher <strong>in</strong> self-adm<strong>in</strong>istered formats (Tourangeau &<br />
Smith, 1996; van der Heijden et al., 2000); b) everyone has agreed to be and expects to be contacted (unlike<br />
telephone surveys); c) the results can be obta<strong>in</strong>ed <strong>in</strong> a much shorter period <strong>of</strong> time; and d) they are roughly onethird<br />
the cost <strong>of</strong> telephone surveys. However, there are several unanswered questions concern<strong>in</strong>g onl<strong>in</strong>e panels.<br />
One concern is the degree to which panels are representative <strong>of</strong> the population. One obvious problem is that a<br />
significant nonrandom m<strong>in</strong>ority <strong>of</strong> people still do not use the Internet. The most recent data for Canada shows<br />
that 27% <strong>of</strong> Canadians 16 and older did not use the Internet <strong>in</strong> 2007, with nonusers significantly more likely to be<br />
located <strong>in</strong> rural areas, have lower <strong>in</strong>come, be older, and have less education (Statistics Canada, 2008).<br />
Furthermore, although onl<strong>in</strong>e panelists are structured to be demographically representative, other differences<br />
likely exist, as only a small m<strong>in</strong>ority <strong>of</strong> people <strong>in</strong>vited to be part <strong>of</strong> an onl<strong>in</strong>e panel agree to participate (Sparrow,<br />
2006). Concerns have also been expressed about the data quality when us<strong>in</strong>g ‘pr<strong>of</strong>essional respondents’ who may<br />
do dozens <strong>of</strong> surveys with<strong>in</strong> the span <strong>of</strong> a few months (Göritz, 2007; Toepoel, Das & van Soest, 2008). Other<br />
questions concern the optimal way <strong>of</strong> creat<strong>in</strong>g onl<strong>in</strong>e panels, the effects <strong>of</strong> different types and magnitudes <strong>of</strong><br />
rewards, the appropriate number <strong>of</strong> contact/request attempts, appropriate deadl<strong>in</strong>e for questionnaire completion,<br />
and the effects <strong>of</strong> nonresponse.<br />
