Smoking intervention in the workplace using videotapes and nicotine chewing gum

Effectiveness of smoking cessation therapies: a systematic review and meta-analysis

“…We found 70 RCTs examining NRT versus control interventions (See Figure 1 and Additional File 1), [30-99] 49 of which compared NRT to placebo [30,32,34,35,38,39,43,44,46,48,50,54,56-59,62,64-69,71-82,84-87,89-91,93,94,96,98,99] thirty one studies compared NRT to other controlled groups (See table 1) [31,33,36,37,40-42,45,49,51-53,55,61,63,70,83,88,92,95,97] and 1 study uses both placebo and no intervention as control group[47]. …”

Randomized trial of brief individual treatment for smoking using nicotine chewing gum in a workplace setting.

“…Our results replicate those of an earlier study also conducted in a workplace setting and using a similar design. 18 Our study was not designed to ascertain the extent to which any observed treatment effect could be attributed to pharmacological factors or whether the gum itself was a necessary component of the treatment. In addition to the gum, the treatment included a number of other components that may have contributed to the treatment effect, for example, giving subjects information about their CO levels.…”

Smoking Cessation Programs in the Workplace

“…Three experimental studies used a videotape as the treatment intervention (Sutton, 1984(Sutton, , 1988Hallett, 1987). The possibility of contamination between experimental and control groups was a concern in each of the studies.…”

“…Success rates ranged from 0% in control groups to 14% for some of the groups who viewed the videotape. Sutton (1988) extended the study by offering nicotine gum to a randomly chosen sub-group who had been involved in the videotape intervention. These individuals were still smoking 3 months post-film viewing.…”

“…Only three of the studies examined predictors of long term success (Gritz, 1988;Sutton, 1984Sutton, , 1988. They identified one common factor-the amount of cigarettes smoked.…”
