Stress and Quality of Life of Patients with Cancer: The Mediating Role of Mindfulness

Abstract EN

Background.

Cancer is one of the major health problems worldwide, which in addition to physical disorders, causes stress and anxiety in patients and affects the quality of life of cancer patients.

Mindfulness can affect stress and improve the quality of life.

This research explained the correlation between stress, quality of life, and mindfulness.

Materials and Methods.

Two hundred five cancer patients participated in this cross-sectional study.

Patients completed the EORTC Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), the Mindfulness Attention and Awareness Scale (MAAS), and Perceived Stress Scale (PSS).

Results.

Perceived stress and mindfulness predict nearly 39% of the changes of QOL in cancer patients.

In addition, perceived stress was negatively associated with mindfulness and quality of life P<0.05.

Mindfulness was positively correlated with quality of life P<0.05.

Mindfulness played a mediating role in the relationship between perceived stress and quality of life (standardized β = −0.13; SE = 0.07, 95% confidence interval = −0.28 to −0.01; P value = 0.04).

Conclusion.

In the present study, the variables of mindfulness and perceived stress affected the quality of life of cancer patients.

Mindfulness can affect the quality of life of cancer patients directly and indirectly.

These results emphasize the importance of mindfulness in the lives of cancer patients.
