Abstract
BackgroundNewer models of palliative and supportive cancer care view the person as an active agent in managing physical and psychosocial challenges. Therefore, personal efficacy is an integral part of this model. Due to the lack of instruments in Italian to assess coping self-efficacy, the present study included the translation and validation of the Italian version of the Cancer Behavior Inventory–Brief (CBI-B/I) and an initial analysis of the utility of self-efficacy for coping in an Italian sample of palliative care patients.Methods216 advanced cancer patients who attended palliative care clinics were enrolled. The CBI-B/I was administered along with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30), the Mini Mental Adjustment to Cancer Scale (Mini-MAC), the Cancer Concerns Checklist (CCL), and the Hospital Anxiety and Depression Scale (HADS). The Eastern Cooperative Oncology Group Performance Status (ECOG-PS) ratings of functional capacity were completed by physicians.ResultsFactor analysis confirmed that the structure of the CBI-B/I was consistent with the English version. Internal consistency reliability and significant correlations with the EORTC QLQ-C30, Mini-MAC, and HADS supported the concurrent validity of the CBI-B/I. Differences in CBI-B/I scores for high versus low levels of the CCL and ECOG-PS supported the clinical utility of the CBI-B/I.ConclusionsThe CBI-B/I has strong psychometric properties and represents an important addition to newer model of palliative and supportive care. In order to improve clinical practice, the CBI-B/I could be useful in identifying specific self-efficacy goals for coping in structured psychosocial interventions.
Highlights
Newer models of palliative and supportive cancer care view the person as an active agent in managing physical and psychosocial challenges
Our analyses revealed that the Cancer Behavior Inventory–Brief (CBI-B)/I had the same structure as the original English version [5], was reliable, valid, and has clinical utility
The composite index of Cancer Behavior Inventory–Brief (CBI-B/I) was positively correlated with the overall quality of life, as well as the EORTC Quality of Life Questionnaire-Core 30 (QLQ-C30) subscales that measure physical, emotional, role, and social functioning: these results demonstrate that palliative care patients with higher scores on self-efficacy for coping with cancer have better quality of life
Summary
Newer models of palliative and supportive cancer care view the person as an active agent in managing physical and psychosocial challenges. The evidence for the importance of self-efficacy for coping in the context of palliative and supportive care is connected to its relationship with self-care and with adjustment and quality of life. Baile, Palmer, Bruera, & Parker [10] found negative correlations between number of concerns (e.g., needing more information about illness/treatment, not being able to do usual activities, caring for self ) and coping self-efficacy in palliative care patients. In patients with advanced disease, cancer self-efficacy expectations, which included coping self-efficacy, activities of daily living (ADL) efficacy, and affect regulation self-efficacy, Serpentini et al BMC Palliative Care (2019) 18:34 mediated the relationship between functional status and emotional well-being, mitigating the negative effects of physical limitations on emotional well-being [11]. A mediating effect of coping self-efficacy in the relationship between symptoms and depression was found in a sample of cancer survivors who were on the average 9.3 years post diagnosis [12]
