Coping strategies of patients with advanced lung or colorectal cancer over time : insights from the international ACTION study

Objective A comprehensive understanding of coping strategies of patients with advanced diseases can contribute to providing supportive care that meets patients' needs. However, insight into how coping of this population develops over time is lacking. We examined coping strategies of patients with advanced cancer over time and identified distinct trajectories and their predictors. Methods Data from 675 patients of the control group from the ACTION cluster-randomized trial were analyzed. Patients with lung or colorectal cancer from six European countries (Belgium, Denmark, Italy, the Netherlands, Slovenia and the United Kingdom) completed questionnaires at baseline, 12 and 20 weeks. Measures included Denial, Acceptance, and Problem-focused coping (COPE, Brief COPE inventory; scores 4-16 per scale). We used linear mixed models to analyze the data and latent class mixed models to identify stable (within patient change < 2) coping strategies. Results At baseline, patients reported low use of Denial (6.6) and greater use of Acceptance (12.6) and Problem-Focused coping (12.2). These scores did not significantly change. We found four distinct trajectories for the use of Denial, three for Acceptance and five for Problem-Focused coping strategies. Stable trajectories were found in 513 (77%) patients for Denial, 645 (96%) for Acceptance and 602 (91%) for Problem-Focused coping. All coping strategies were stable in 447 (68%) patients and two were stable in 181 patients (28%). Conclusions Overall, the use of coping strategies was rather stable in the majority of patients with advanced cancer. However, for each of the coping strategies subgroups of patients reported fluctuating coping trajectories.
