INTRODUCTION: Recruiting special populations to smoking cessation trials is challenging and approaches beyond in-clinic recruitment may be beneficial. This secondary analysis of data from a smoking cessation RCT for individuals with a history of cervical cancer or cervical intraepithelial neoplasia (CIN) explored differences associated with in-clinic vs. online recruitment. AIMS AND METHODS: Participants were recruited from clinics within a university-based NCI-designated cancer center (n = 87) and online nationally via Facebook (n = 115). Baseline measures included sociodemographics, smoking history, and cancer or CIN history. Study retention and smoking abstinence were assessed 12 months post-baseline. Group differences in baseline characteristics were evaluated. Retention and abstinence were evaluated while controlling for group differences and predictors. RESULTS: Participants recruited online (vs. in-clinic) had higher educational attainment (p = .01) and health literacy (p = .003). They were more likely to have CIN versus cancer, to be further from the time of diagnosis, and to have completed active treatment (p values < .001). While controlling for these group differences and independent predictors, retention was higher among participants recruited online (log-likelihood χ2(1) = 11.41, p < .001). There were no recruitment differences in self-reported (p = .90) or biochemically confirmed smoking abstinence (p = .18). CONCLUSIONS: Compared to individuals recruited in-person, individuals recruited online were more educated, had higher health literacy, and presented with a different clinical profile (ie, more likely to have CIN vs. cancer and to have completed active treatment). There were few differences in participant characteristics between recruitment approaches, and no differences on any smoking-related variables. Online recruitment has the potential to improve enrollment of cancer survivors in smoking cessation trials. IMPLICATIONS: People with a history of CIN or cervical cancer recruited to a smoking cessation RCT online (vs. in-clinic) were more likely to have a diagnosis of CIN versus cancer and were more educated and health literate. Participants recruited online were more likely to be retained in the study and there were no differences in smoking abstinence rates at 12 months. Incorporating online recruitment increased the reach of tobacco treatment efforts to a larger and more diverse sample. This could reduce the burden of tobacco-related disease, improve CIN and cancer treatment outcomes, and reduce secondary malignancies and morbidity among this underserved group.
