Abstract: Objectives: The relevance of the social context in the study of
coping with chronic illness has been increasingly recognised. Dyadic coping is
the central concept within the systemic process model of coping in close
relationships. To measure dyadic coping, the Questionnaire for the Assessment
of Dyadic Coping (QADC) was developed. In this study, we aimed at
investigating the factorial structure of a version of this questionnaire known
in German as FDCT-2. Methods: We conducted a principal components analysis. The
study sample comprised N=197 persons from the general population. Results:
The analysis did not replicate the original factor structure. Instead, a
four-factorial solution emerged that showed rather weak properties. We
developed a revised version (FDCT-25) comprising the four factors stress
communication, problem-oriented dyadic coping, emotion-oriented dyadic coping,
and negative dyadic coping. These revised scales showed adequate internal
consistency. Conclusion: Our results question the construct validity of the
QADC in its original version and underline the need to further investigate the
validity of the QADC.
