Abstract
OBJECTIVE: Thanks to rapid penetration of mobile tools, more and more cancer survivors have adopted mobile-based patient-provider communication (MBPPC). The relationship between MBPPC and patients' health outcomes, however, remains unclear; how health literacy and patient activation interact with such relationship is unexplored. METHODS: Data were drawn from National Cancer Institute's Health Information National Trends Survey 4 Cycle 3. A sample of 459 cancer survivors were included in the analysis. Based on the 3-stage model of health promotion using interactive media, this study empirically tested a moderated mediation model. RESULTS: MBPPC (eg, patient use of email, text message, mobile app, and social media to communicate with providers) had no direct effect on cancer survivors' emotional health. Instead, health literacy completely mediated this path. Patient activation positively moderated the effect of health literacy on emotional health and further increased the indirect effect of MBPPC on emotional health. CONCLUSIONS: MBPPC alone does not directly result in better emotional health outcomes; health literacy is the key to realize its health benefits; patient activation significantly strengthens the effects of MBPPC. As we embrace the mHealth movement, innovative programs are needed to promote MBPPC, and improve health literacy and activation of cancer survivors, particularly in underserved communities, to reduce health disparities.
