British Columbia Lottery Corporation established a Voluntary Self-Exclusion (VSE) program in the fall of 1998. The program was established to allow people to exclude themselves from casinos, venues with slot machines and/or commercial bingo halls across British Columbia. In 2007 the program was expanded to include VSE from PlayNow, BCLC’s internet gaming site. However, the program’s effectiveness with program participants had not been evaluated. The BC Centre for Social Responsibility is currently conducting the longitudinal four-year study on behalf of BCLC. This evaluation uses two distinct methodologies: (1) focus groups with a sample of BCLC staff and service providers and (2) telephone interviews with a voluntary sample of VSE participants currently enrolled in the program. This interim report will provide preliminary analysis of the interview data. The interim results indicate a fairly high level of support for the VSE program among participants, although it is important to keep in mind that the participants also have many views on how the VSE could work better for them. This interim report includes some analysis of the factors associated with VSE violations, who is most likely to attempt to violate and ways in which the deterrent effect of the program may be strengthened.
