Everyday protective buffering predicts intimacy and fear of cancer recurrence in couples coping with early-stage breast cancer

Objective: Patient and spouse/partner mutual self-disclosure is central for maintaining intimacy and cognitive processing when transitioning to life after cancer. Protective buffering inhibits self-disclosure and is defined as efforts to protect one's partner from upset and burden by hiding or denying cancer-related concerns. Intimacy and fear of cancer recurrence (FCR) are important determinants of individual and couple adaptation following cancer. Links between protective buffering and intimacy have not been examined in the context of daily life, and links with FCR have not been studied. We hypothesized that protective buffering is associated with decreased intimacy and increased FCR at a daily, within-person level.

Methods: Sixty-nine early-stage breast cancer (BC) survivors and their spouses completed electronic diaries for 21 consecutive days at the end of adjuvant treatment. Patients and spouses reported on daily protective buffering, intimacy, and FCR. Dyadic multilevel path modeling was used to estimate within-person effects. Patient and spouse protective buffering on one's own as well as one's partner's same-day intimacy and FCR were examined, controlling for previous levels of intimacy and FCR.

Results: Protective buffering was associated with decreased intimacy and increased FCR for the individual reporting buffering that same day. Patient and spouse protective buffering was also linked to decreased intimacy for her/his partner that same day. Moreover, patient protective buffering predicted increased spouse FCR that same day.

Conclusions: Findings supported a daily, within-person link between buffering, intimacy, and FCR, suggesting open disclosure of cancer-related concerns may be a relevant target for interventions for adaptation to BC.
