In the study, an analysis value of one variable to another (for example, physical activity and fatigue) and analyzed as one variable (samoefektyvnist) could affect other variables directly and indirectly. Physical activity has provided a direct impact on samoefektyvnist. In turn, samoefektyvnist provided direct effect on fatigue and an indirect effect through depressive semiology. However, controlling the effect of self-efficacy on depression and fatigue significantly reduced the impact of physical activity on depression and fatigue. Comparison of potential troublemakers, such as demographics and health status did not change the statistical significance of these relationships. The researchers concluded: support for at least one set psihosotsiolohicheskiy pathways of physical activity to fatigue, has an important effect in chronic disease. The following studies can be carried out in other groups of patients to try to determine whether the patient’s condition changes by increasing physical activity and the ability to include this model in other known factors of fatigue, such as impaired sleep and inflammation.
The study showed that the effect of physical activity on samoefektyvnist explains the relationship between physical activity and reduced fatigue in people who have survived breast cancer and those with multiple sclerosis. Confidence reduces depression, which in turn reduces fatigue. An increase in self-efficacy and reduces fatigue. This means that programs to increase physical activity should include efforts to increase self-efficacy, which in turn increases the welfare of man.
