Mindfulness Affects the Level of Psychological Distress in Patients With Lung Cancer via Illness Perception and Perceived Stress: A Cross-Sectional Survey Study

Abstract

PurposeThe aims of the study were first to investigate the association between illness perception and psychological distress and second to determine whether mindfulness affects psychological distress via illness perception and perceived stress in patients with lung cancer.MethodsAmong 300 patients with lung cancer who participated in this cross-sectional study, 295 patients made valid responses to distress thermometer (DT), the Five Facet Mindfulness Questionnaire (FFMQ), the Brief Illness Perception Questionnaire (B-IPQ), and the Perceived Stress Scale (PSS) between January and July 2021. The possible pathways of mindfulness affecting psychological distress were analyzed based on the structural equation modeling analysis.ResultsA total of 24.4% patients with lung cancer had DT > 4. Illness perception (β = 0.17, p = 0.002) and perceived stress (β = 0.23, p < 0.001) had a direct effect on psychological distress. Mindfulness had a direct effect on illness perception (β = −0.16, p = 0.006) and mindfulness indirectly influenced psychological distress (β = −0.04, p = 0.009) through affecting illness perception alone or simultaneously affecting both the illness perception and perceived stress in patients with lung cancer.ConclusionLung cancer suffered from varying levels of psychological distress. Mindfulness may alleviate psychological distress by reducing the level of illness perception and perceived stress. We suggest developing a comprehensive factor model to clarify potential mechanisms of mindfulness on psychological distress due to the very low effect of mindfulness on psychological distress via illness perception and perceived stress.

Treatment-induced menopause symptoms among women with breast cancer undergoing chemotherapy in China: a comparison to age- and menopause status–matched controls

“…This study also explored the relationship between illness perception and menopause symptoms in women with breast cancer undergoing chemotherapy. Illness perception is an important cognitive factor during treatment and is significantly associated with psychological symptoms and behaviors in women with cancer 46-48 . These findings emphasize the necessity of integrating these factors when developing interventions designed to improve the well-being and health of women with breast cancer undergoing chemotherapy.…”

Efficacy and mechanisms of 4-week MBSR on psychological distress in lung cancer patients: A single-center, single-blind, longitudinal, randomized controlled trial

“…Both mindfulness 89 and social support 90 are positive sources for copying with negative psychological states, and our previous studies have demonstrated the inverse association between mindfulness and social support and psychological distress. 15 , 56 , 58 In contrast, stigma, a negative emotional experience that includes isolation, rejection, degradation, and criticism due to undesirable conditions, 77 has been demonstrated to be a predictor of psychological distress in patients with lung cancer. 47 In general, psychosomatic balance plays a vital role in regulating the psychological well-being of patients with cancer.…”

“… 54 , 55 In addition, our previous studies explicitly investigated the roles of social support, perceived stigma, perceived stress, coping styles, self-esteem, mindfulness, and illness perception in the development of psychological distress in patients with lung cancer. 15 , 56 , 57 , 58 However, it remains unclear which pathways may mediate the interventional effects of the MBSR program on psychological distress in patients with lung cancer.…”
