The reciprocal relationship between coping mechanisms and lung cancer diagnosis: Findings of a prospective study

Abstract

Background/purpose: Lung cancer is a major stress factor for the affected individual, leading to psychological distress in over 50% of the diagnosed patients. Since coping styles describe different patterns in approaching serious problems, our study aimed at ascertaining if the diagnosis of lung cancer has an impact on the patient’s coping styles and if there is a difference in psychical response among patients with different coping styles, as assessed by variance of anxiety and depression scores after diagnosis. Patients and methods: In this prospective study, a cohort of 50 patients were evaluated using the COPE scale, Generalized Anxiety Disorder Questionnaire 7 (GAD-7), and Patient Health Questionnaire-9 (PHQ-9), both prior to and 1 month after learning about their lung cancer diagnosis. The baseline and the final parameters were compared and stratified with respect to coping styles. Results: We observed that 1 month after learning the diagnosis, the patients had a significantly higher GAD-7 score (median score 12 vs 4 points; p<0.001). At the same time, the PHQ-9 score was significantly higher at the 1 month follow-up time-point (median score 16 vs 7; p=0.002). The increases in the anxiety scores were significant in patients with initial social support (13 vs 3; p=0.014) and avoidance coping style (14 vs 6; p=0.003). Regarding the depression scores, after the diagnosis, the only significant increase was observed in patients with initial avoidance coping style (18 vs 5; p=0.014). Conclusion: Our study demonstrates that patients who receive the diagnosis for cancer show a significant increase in anxiety and depression intensity. The most adaptive coping style turned out to be the problem-focused one while the least adaptive one was the avoidant style.
