However, there is little knowledge about the application of the transtheoretical model to explain physical activity behavior in individuals with non-cystic fibrosis bronchiectasis. The aim was to examine patterns of (1) physical activity and (2) mediators of behavior change (self-efficacy, decisional balance, and processes of change) across stages of change in individuals with non-cystic fibrosis bronchiectasis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>METHODS:<\/jats:title>\n                    <jats:p>\n                      Fifty-five subjects with non-cystic fibrosis bronchiectasis (mean age \u00b1 SD = 63 \u00b1 10 y) had physical activity assessed over 7 d using an accelerometer. Each component of the transtheoretical model was assessed using validated questionnaires. Subjects were divided into groups depending on stage of change: Group 1 (pre-contemplation and contemplation;\n                      <jats:italic toggle=\"yes\">n<\/jats:italic>\n                      = 10), Group 2 (preparation;\n                      <jats:italic toggle=\"yes\">n<\/jats:italic>\n                      = 20), and Group 3 (action and maintenance;\n                      <jats:italic toggle=\"yes\">n<\/jats:italic>\n                      = 25). Statistical analyses included one-way analysis of variance and Tukey-Kramer post hoc tests.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>\n                      Physical activity variables were significantly (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .05) higher in Group 3 (action and maintenance) compared with Group 2 (preparation) and Group 1 (pre-contemplation and contemplation).

Decisional balance cons (barriers to being physically active) were significantly lower in Group 3 versus Group 2 (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .032). For processes of change, substituting alternatives (substituting inactive options for active options) was significantly higher in Group 3 versus Group 1 (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .01), and enlisting social support (seeking out social support to increase and maintain physical activity) was significantly lower in Group 3 versus Group 2 (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .038).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSIONS:<\/jats:title>\n                    <jats:p>The pattern of physical activity across stages of change is consistent with the theoretical predictions of the transtheoretical model.
