Assessment of self-efficacy and coping with cancer: development and validation of the cancer behavior inventory.
This article reports the development of a measure of self-efficacy for coping with cancer. Items culled from a variety of sources were chosen for inclusion in the Cancer Behavior Inventory (CBI) based on the psychometric properties of the items and the fit of the items in a factor structure. Factor analysis on a group of 502 persons with cancer yielded 6 factors: (a) Maintenance of Activity and Independence (alpha = .89), (b) Coping With Treatment-Related Side Effects (alpha = .88), (c) Accepting Cancer/Maintaining Positive Attitude (alpha = .87), (d) Seeking and Understanding Medical Information (alpha = .88), (e) Affective Regulation (alpha = .75), and (f) Seeking Support (alpha = .77). Cronbach's alpha for the entire measure was .96, and correlations with other measures supported its validity. The CBI may be useful for research and clinical practice.
