2008 Survey
APPENDICES
Appendix A: 2008 and 2009 Alberta Population Surveys
Consumer Contact, with corporate offices in Toronto, Ontario, conducted both the 2008 and
2009 surveys. The 2008 survey was conducted between June 11 and August 31, 2008.
The following procedures were used to ensure optimal random sampling and valid self-report
for the telephone surveys (see Williams & Volberg, 2010):
In June of each year, the Principal Investigator on this project, Dr. Robert Williams,
conducted a 2 hour training session with the survey management team and all of their
interviewers.
The household interviewee was randomly selected by requesting the interview be
conducted with the adult (18+) having the next birthday.
Maximal effort was made to complete an interview with the randomly designated person.
o There were 16 attempts to contact the person, with a maximum of 2 call
attempts per evening. The average number of contact attempts for completed
interviews was 7.25.
o The majority of the phoning occurred in the evening and on weekends.
The interviewer’s work received periodic visual and audio monitoring for quality control by
a supervisor.
The interview was kept short to maximize response rates. The average interview length for
completed interviews was 14.23 minutes.
Sample
There were 3 samples collected in 2008:
General Population Telephone Sample (N = 3,001).
o This sample was recruited by means of random digit dialling of Alberta telephone
numbers. The telephone number databank from which numbers were randomly
drawn included unlisted numbers, but excluded cell phones to reduce multiple
sampling of the same household.
o A minimum sample size of 3,000 was sought and a minimum quota of 40% male
respondents was required.
Targeted Telephone Sample (N = 4,512).
o A minimum total sample size of 4,500 was sought with a minimum of 500 people
sampled from each of the 9 following geographic areas: 4 areas that did not
have casinos prior to their introduction in late 2007/early 2008 (Cold Lake area;
Whitecourt area; Camrose area; Morley area), and 5 areas that have had casinos
for many years (Fort McMurray area; Grande Prairie area; Red Deer area;
Medicine Hat area; Lethbridge area).
