title: Coping with breast cancer and relapse: Stability of coping and long-term outcomes in an observational study over 10 years.
abstract: Many studies dealing with relationships between coping and breast cancer were based on a single measurement of coping behaviour. Assessments were taking place soon after surgery of primary breast cancer, and effects on long-term outcomes were considered. In our study it was examined whether coping behaviours are stable over time and whether they were associated with breast cancer recurrence. The analyses were based on a long-term study with initially 254 patients with three interviews and an outcome assessment within a total study period of 10 years. Data were collected by means of qualitative interviews and standardized questionnaires. Ways of coping in terms of helplessness, denial, mastery, and hope/optimism were classified by interviewer-based ratings within the framework of a standardized rating procedure. The reliability of rating standards was assured by continuous training and by estimating inter-rater agreements. Outcome measures were drawn from registries and patients' files. Coping behaviours over three interviews within six years after surgery turned out to be highly variable, and the respective correlations were low. For none of the four ways of coping associations with recurrence emerged. Coping in response to breast cancer was not stable over time, so we may conclude that the results of one measurement assessed early in the disease course should not be considered as constant over longer time periods. Coping behaviours were unrelated with recurrence, a finding that might be relieving from a patient perspective.
