Testing a model of exposure to environmental tobacco smoke in military women with children.
The purpose of this study was to test a model of exposure to environmental tobacco smoke (ETS) in military women and their children. The convenience sample consisted of 238 women, 81 smokers and 157 nonsmokers, with a mean age of 37 years (SD = 9.9). Participants were either on active duty or were reservists and/or military dependents. Model constructs, some of which were adapted from the transtheoretical model of behavior change, measured personal and situational factors, pros and cons of ETS exposure, self-efficacy to resist ETS, mother's expectation for child's ETS exposure, and mother's self-efficacy to reduce child's ETS exposure. The mediating variable was the mother's daily ETS exposure, and the outcome variable was the child's daily ETS exposure. The trimmed model showed that 32% of the variance in mother's daily exposure (mediating variable) was accounted for by living with a smoker, having high ETS "pros" (as opposed to ETS "cons"), having less self-efficacy to resist ETS, and having greater self-efficacy to reduce the child's exposure. There was a significant, positive relationship (r = 0.51, p = 0.01) between the mother's and child's daily ETS exposure (outcome variable).
