      abstract     = {Previous research has shown that structural barriers
                      negatively influence the physical activity (PA) behavior of
                      cancer patients, but underlying mechanisms are unclear. The
                      aim of the current study was to explore the potential
                      mediating role of social-cognitive factors, namely PA
                      self-efficacy and PA intention in this context. A total of
                      856 cancer patients completed a questionnaire on
                      sociodemographic and medical characteristics, pre- and
                      post-diagnosis PA, PA self-efficacy, PA intention, and PA
                      impediment by structural barriers. A serial mediation model
                      was used to test whether the association between structural
                      barriers and post-diagnosis PA was mediated by PA
                      self-efficacy and/or PA intention, in the overall sample and
                      in subsamples defined by individuals' pre-diagnosis PA. The
                      results confirmed that structural barriers were not directly
                      $(95\%CI$ [-0.45; 0.10]) but indirectly associated with
                      post-diagnosis PA. Higher impediment by structural barriers
                      decreased the likelihood of sufficient post-diagnosis PA via
                      lower PA self-efficacy $(95\%CI$ [-0.25; -0.06]) and via the
                      serial pathway of lower PA self-efficacy and lower PA
                      intention $(95\%CI$ [-0.19; -0.05]). Investigating
                      differences in these mediations by pre-diagnosis PA yielded
                      significance only among previously active cancer patients.
                      Both structural barriers and PA self-efficacy might hence be
                      relevant target points for interventions aiming to improve
                      PA behavior, especially among pre-diagnosis active cancer
                      patients.},
