The mutual determination of self-efficacy to cope with cancer and cancer-related coping over time: a prospective study in women with breast cancer

OBJECTIVE

The aim of this study was to examine the longitudinal impact of self-efficacy to cope with cancer on the cancer-related coping reactions of breast cancer patients and vice versa.

DESIGN AND MAIN OUTCOMES MEASURES

Data from the BOUNCE Project (https://www.bounce-project.eu/) were used to address the hypotheses. Participants (N = 403) were enrolled in the study a few weeks after surgery or biopsy. Coping self-efficacy was assessed at baseline and six months later (M6). Cancer-related coping was assessed three (M3) and nine months (M9) after baseline. The analyses were performed using structural equation modeling with Mplus 8.6.

RESULTS

Baseline coping self-efficacy predicted all M3 coping reactions, while M6 coping self-efficacy also predicted changes in all but one M9 coping reaction. Moreover, one of the M3 coping reactions, that is, hopelessness/helplessness, predicted the changes in M6 coping self-efficacy. The relation between coping self-efficacy and one coping reaction (i.e. cognitive avoidance) was rather weak. Stability paths from M3 to M9 coping reactions were moderate to high.

CONCLUSION

The relationship between self-efficacy to cope with cancer and cancer-related coping is complex. New theoretical models are needed to more accurately describe the diverse aspects of this association.

Protective Factors against Fear of Cancer Recurrence in Breast Cancer Patients: A Latent Growth Model

The current study aimed to examine the fear of cancer recurrence (FCR) trajectory and protective predictors in women coping with breast cancer (BC). The study's model investigated whether a higher coping self-efficacy and positive cognitive-emotion regulation at the time of the BC diagnosis would lead to reduced levels of FCR at six months and in later stages (12 and 18 months) post-diagnosis. The sample included 494 women with stages I to III BC from Finland, Italy, Portugal, and Israel. They completed self-report questionnaires, including the Fear of Cancer Recurrence Inventory (FCRI-SF), the Cancer Behavior Inventory-Brief Version (CBI-B), the Cognitive-Emotion Regulation Questionnaire (CERQ short), and medical-social-demographic data. Findings revealed that a higher coping self-efficacy at diagnosis predicted lower FCR levels after six months but did not impact the FCR trajectory over time. Surprisingly, positive cognitive-emotion regulation did not predict FCR levels or changes over 18 months. FCR levels remained stable from six to 18 months post-diagnosis. This study emphasizes the importance of developing specific cancer coping skills, such as coping self-efficacy. Enhancing coping self-efficacy in the first six months after BC diagnosis may lead to lower FCR levels later, as FCR tends to persist in the following year.
