Abstract:
Purpose Psychological distress greatly impaired the psychological and physical well-being of lung cancer patients. Identification of protective and risk factors is a prerequisite of developing effective psychological treatment protocol. The study aims to determine the relationship of mindfulness and psychological distress and further clarify the mechanism of mindfulness against psychological distress through perceived stigma and social support among Chinese lung cancer patients. Method A cross-sectional survey study involving 441 valid Chinese lung cancer patients was conducted from September 2018 to August 2019. After all validated questionnaires that measured psychological distress, level of mindfulness, social support, and perceived stigma were returned by patients, we firstly performed correlation analysis to assess the associations between mindfulness, social support, perceived stigma, and psychological distress. Then structural equation modelling analysis was conducted to further clarify the mediating effects of perceived stigma and social support on the relationship between mindfulness and psychological distress. Results According to our hypothesis and further modification, our revised model adequately fits to data. Mindfulness (beta = - 0.107, p = 0.008) and social support (beta = - 0.513, p < 0.001) had a direct effect on psychological distress. Meanwhile, mindfulness had a direct effect on perceived stigma (beta = - 0.185, p < 0.001), and perceived stigma had a direct effect on social support (beta = - 0.373, p < 0.001). Furthermore, mindfulness had also the indirect effect on psychological distress through the chain mediating role of stigma and social support among lung cancer patients. Conclusions Mindfulness has direct negative effect on psychological distress and has also indirectly negative psychological distress through impacting social support and perceived stigma.
