High sedentary time (SED) is a public health concern and reductions of SED may significantly improve health outcomes. Perceptions, determinants, and associations with other health aspects, such as pain, are understudied. The purpose of this dissertation was to 1) examine the relationship between SED and pain symptoms and pain processing in people with chronic low back pain (cLBP), 2) compare levels of self-efficacy for reducing SED to increasing moderate to vigorous physical activity (MVPA), and 3) explore perceived determinants of reducing SED in people with cLBP. Results from study one suggests no relationship between SED and pain in people with cLBP. Study two results show that people are more confident in their ability to reduce SED compared to increase MVPA, and adults have similar levels of confidence in meeting daily SED related goals. Study three found that common barriers for reducing SED include environmental constraints, social norms, and productivity, while helping individuals develop coping plans, restructure their physical environments, develop habits surround sitting less, and using self-monitoring tools are perceived as helpful. This dissertation adds to current literature on associations between SED and pain, and perceptions and determinants of reducing SED. This may help in the refinement of SED interventions for treatment of cBLP and other health outcomes, as well as in understanding confidence for changing SED and MVPA behaviors to potentially aid in refinement of current SED and MVPA guidelines.
