Impact of Psychological Support on Motivation for Physical Activity in Colorectal Cancer Patients
Abstract
Introduction: This study investigates the psychosocial determinants of physical activity (PA) in colorectal cancer (CRC) patients, specifically examining the influence of perceived autonomy support from healthcare providers on exercise behavior. Methods: A cross-sectional analytical study was conducted among 72 patients with CRC using two validated scales. Perceived autonomy support was assessed via the Health Care Climate Questionnaire (HCCQ). Motivation to exercise during oncology treatment was measured using the Treatment Self-Regulation Questionnaire (TSRQ). Relationships were analyzed using the computed mean item scores of both instruments. Results: The study results showed a slight male predominance (sex ratio: 1.25) with a mean age of 56±11.94 years. Diagnosis was predominantly late (84.7%), with a high prevalence of stages III and IV (84.7%). Furthermore, the study revealed a non-self-determined profile (index: -2.2), characterized by a healthcare environment perceived as controlling (HCCQ: 2.71). Patients engaged in physical exercise primarily out of guilt or external pressure (controlled regulation score: 5.11) rather than personal conviction (autonomous regulation score: 2.86). Educational level significantly influenced the perception of autonomy support (p = 0.03), to the detriment of the most and least educated patients. Conversely, participants' age and clinical stage (TNM) had no statistically significant impact on the various psychological dimensions assessed (p > 0.05). Conclusion: In light of patient engagement being driven by external constraint, care in colorectal oncology must shift from directive prescription to autonomy support. To achieve this, integrating therapeutic patient education is essential to facilitate the internalization of the health benefits of exercise. Finally, establishing progressive goals proves indispensable for restoring self-efficacy and consolidating the patient’s perceived competence prior to any focus on functional performance.
