The Cancer Coping Questionnaire: A self-rating scale for measuring the impact of adjuvant psychological therapy on coping behaviour.

摘要

The Cancer Coping Questionnaire is a brief, self-rating scale designed to measure coping strategies taught in Adjuvant Psychological Therapy. This paper describes the development of the 21 item Cancer Coping Questionnaire (CCQ) in a sample of 201 patients with mixed cancers. The construct validity and reliability of the instrument are reported from work on 3 samples (a mixed cancer group, n=42; women with breast cancer, n=50; and a group of patients referred for psychological help, n=48). The CCQ showed very good internal reliability and test-retest reliability. As hypothesised cancer patients with more psychological morbidity demonstrated lower CCQ scores, and the CCQ correlated with measures of adjustment to cancer. Compared with an established coping inventory (the Coping Responses Indices; CRI) the CCQs overall individual scale (items 1-14) assessed similar coping areas, particularly in relation to the CRIs foci of coping. The CCQ correlated with Active Behavioural Coping methods on the CRI. The study did not demonstrate sufficiently consistent results concerning the Interpersonal Scale of the CCQ to confirm its validity. Further psychometric work is needed, but the study demonstrated the reliability and validity of the CCQ, supporting the view that change in CCQ scores with cognitive therapy indicates improvement in coping.
