A Study on the Intervention Model of Gastrointestinal Reactions Based on Self-efficacy Theory in Lung Cancer Patients During Chemotherapy

Background: Although there are many studies on clinical intervention of gastrointestinal reactions induced by chemotherapy, the methods and means of intervention are inconsistent and the results differ greatly. More importantly, there are fewer relatively uniform intervention models with theoretical support. Therefore, based on the self-efficacy theory and its framework, the aim of this study was to construct an intervention model of gastrointestinal reactions in patients with lung cancer undergoing chemotherapy and evaluate its effects of clinical application. Methods: Based on self-efficacy theory, a intervention model of gastrointestinal reactions was constructed and applied to 30 patients with lung cancer who had gastrointestinal reactions during chemotherapy for three consecutive chemotherapy cycles. Results: After three cycles of intervention, the analysis of repeated measurement data showed that there was decreased in the total score of gastrointestinal reactions induced by chemotherapy, as well as in yield and psychological distress, and at the same time, increased in the scores of self-efficacy, objective support, support utilization and internal control (P<0.05). Conclusion: The intervention model based on the self-efficacy theory is feasible to intervene in the gastrointestinal reactions of patients with lung cancer during chemotherapy. It can improve their self-efficacy and effectively reduce the gastrointestinal reactions.
