The impact of physician support on skin self-examination among melanoma patients: A serial mediation model with self-efficacy and intentions to perform skin exams

Abstract

ObjectiveMelanoma is the most lethal of skin cancers; however, survival rates are excellent if the tumor is detected early. Clinical practice guidelines for melanoma follow-up care recommend regular skin self-examination (SSE) for individuals at high risk for melanoma. The current analyses tested whether self-efficacy for SSE and intention to perform SSE mediate the relationship between physician support for SSE and SSE behavior among a sample of melanoma patients. Methods: We ran a serial mediation model on a cross-sectional sample of melanoma patients (n = 154) drawn from an observational study with longitudinal follow-up. Results: Self-efficacy and intention to perform SSE sequentially mediated the relationship between physician support and SSE behaviors (β = .31, t(152) = 3.61, p < .001 without mediators versus β = .11, t(150) = 1.50, p = .14 with mediators), as supported by a significant total indirect effect (β = .21, [95 % CI = .08–.35]). ConclusionSelf-efficacy for SSE and intention to perform SSE together explain the link between perceived physician support for SSE and the practice of SSE. Practice ImplicationsPhysician communication about the importance of SSE plays an important role in encouraging patient adherence to SSE recommendations and, thus, supporting early detection efforts.
