Abstract
PURPOSE
To validate the Cancer Behavior Inventory version 3.0 - Korean (CBI 3.0 - K), a holistic measure of self-efficacy for coping with cancer by including spiritual coping subscale.
METHOD
Psychometric properties of the CBI 3.0 - K were evaluated among 453 cancer patients. Confirmatory factor analysis was conducted to examine structural validity. Internal consistency was measured with Cronbach's alpha. For convergent validity, correlations with the Functional Assessment of Cancer Therapy-Gastric Gastric Cancer Subscale (GaCS), the Hospital Anxiety and Depression Scale (HADS), the Multidimensional Scale of Perceived Social Support (MSPSS), the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being (FACT-Sp) subscale and the European Organization for Research and Treatment of Cancer quality of life questionnaire (EORTC QLQ-C30) Global Health Status/QoL subscale were analyzed.
RESULTS
The CBI 3.0 - K supported the original 7 factor structure of the CBI Version 3.0 with relocation of one item which reflected self-efficacy for coping utilizing personal resources. High levels of internal consistencies were demonstrated. Convergent validity was established with moderate to strong correlations with the GaCS, the HADS, the FACIT-Sp, and the EORTC QLQ-C30 subscales, and moderate correlation with the MSPSS. Known group validity with the Using Spiritual Coping subscale was demonstrated.
CONCLUSIONS
The CBI 3.0 - K will facilitate comprehensive assessment of patients' self-efficacy for coping by including spiritual coping subscale. Assessment on responsiveness of the CBI 3.0 - K to interventions designed to enhance coping is strongly recommended.
