Resumen:
This thesis aims to develop a valid predictive tool for identifying lung cancer patients at high risk for psychological distress, to explore possible psychosocial mechanisms of psychological distress in lung cancer patients, to further evaluate the role of mindfulness-based stress reduction (MBSR) in treating lung cancer patients, and ultimately to evaluate the efficacy of a 4-weeks MBSR program on psychological distress in lung cancer patients and elucidate possible psychosocial mechanisms of exerting efficacy. This thesis designs seven separate studies based on the cross-sectional survey, systematic review and meta-analysis, and randomized controlled trial (RCT), and various methods, such as correlation analysis, repeated measure analysis of variance (ANOVA), and structural equation modeling, are used to achieve research objectives in the above studies. Based on these seven studies, this thesis develops an easy-to-use predictive algorithm with moderate accuracy to identify patients at high risk of psychological distress, reveals that social support may directly contribute to ameliorate psychological distress, or may indirectly contribute to ameliorate psychological distress by enhancing confrontation coping with cancer, decreasing perceived stress, and increasing self-esteem, unfolds that mindfulness may indirectly alleviate psychological distress by enhancing social support, decreasing perceived stigma, and reducing the level of illness perception and perceived stress, demonstrates the positive effects of MBSR on psychological states in lung cancer patients, shows the benefits of the 4-weeks MBSR for psychological distress, social support, mindfulness, and perceived stigma in lung cancer patients, and also elucidates the mechanisms by which the MBSR alleviate psychological distress by improving social support, enhancing mindfulness, and decreasing perceived stigma.
