This study examines the variability and stability of coping in cancer
subjects over time and situation. In a prospective longitudinal design
74 breastcancer patients have been followed for 3-5 yr at 3-6 monthly
intervals. A variety of measures related to coping and adjustment wer
e taken. This report limits itself to the findings of an instrument de
veloped for this study, the Bernese Coping Modes in which 26 coping mo
des were rated by observers. Results confirm arguments in favour of bo
th variability and stability in coping activity over time and situatio
n. Two measures support stability: rank values and a multivariate meas
ure (MDS) with three constant dimensions: (1) support and acceptance;
(2) denial; (3) diversion by thought and action. Evidence for variabil
ity is: the potential range of coping modes and a large variety of add
itional modes at most observation times. Subsequently time measures of
coping were attributed to eight predefined illness stages as distinct
clinical situations. Thus variability or richeness of coping further
increased. The implications of these findings for measurement in copin
g research are discussed.
