||Evaluation of Self Help Smokeeless Tobacco Cessation
DESCRIPTION: This study evaluates the effectiveness of an assisted
self-help intervention for smokeless tobacco (SLT) cessation. The primary
aim is to evaluate sustained (6-week and 12-month) cessation effects of the
intervention. Secondary aims include assessment of the spontaneous quit
rate by conducting a random-digit-dialed telephone survey of SLT users in
Oregon, Washington, and Idaho; comparison of intervention quit rates with
estimates from the telephone survey; assessment of the relationship between
baseline demographic and psychosocial variables and SLT cessation and
maintenance; economic analysis to determine relative cost-effectiveness,
assessment of the impact of other tobacco use on SLT cessation, and process
evaluation of intervention components.
Subjects will be recruited from three Northwest states, and adults who
express an interest in quitting their use of SLT will be screened by
telephone for eligibility. Eligible subjects (estimated N 1,026) will be
randomized to receive either (1) a self-help manual only (control), or (2) a
self-help manual, a video tape on quitting, and two supportive phone calls
(Assisted Self-Help condition).
In Phase One of the study, the intervention and assessment will be developed
and piloted. Phase Two will involve subject recruitment, randomization of
subjects to the two conditions, and intervention and assessment. Phase Two
also includes a random-digit-dialed telephone survey to interview 1,100 SLT
users about current use, quit attempts, and interest in quitting. Phase
Three involves one-year follow-up with all intervention subjects and with
phone survey participants who were SLT users at baseline. Phase Four
involves analysis of results, preparation of manuscripts, and revision of
materials for dissemination.
Data from this study can significantly contribute to our understanding of
how to provide effective, low-intensity programs to help adults quit their
use of snuff or chewing tobacco.
