Introduction: Recent reviews have reinforced the notion that having a supportive
spouse can help with the process of coping with and adjusting to cancer.
Congruence between spouses’ perspectives has been proposed as one mechanism in
that process, yet alternative models of congruence have not been examined
closely. This study assessed alternative models of congruence in perceptions of
coping and their mediating effects on adjustment to breast cancer.
Methods: Seventy-two women in treatment for breast cancer and their
husbands completed measures of marital adjustment, self-efficacy for coping,
and adjustment to cancer. Karnofsky Performance Status was obtained from
medical records. Wives completed a measure of self-efficacy for coping (wives’
ratings of self-efficacy for coping [WSEC]) and husbands completed a measure of
self-efficacy for coping (husbands’ ratings of wives’ self-efficacy for coping
[HSEC]) based on their perceptions of their wives’ coping efficacy.
Results: Interestingly, the correlation between WSEC and HSEC was only 0.207;
thus, they are relatively independent perspectives. The following three models
were tested to determine the nature of the relationship between WSEC and HSEC:
discrepancy model (WSEC - HSEC), additive model
(WSEC + HSEC), and multiplicative model (WSEC × HSEC). The
discrepancy model was not related to wives’ adjustment; however, the additive (B =0.205, P <0.001) and multiplicative (B =0.001, P <0.001) models were
significantly related to wives’ adjustment. Also, the additive model mediated
the relationship between performance status and adjustment.
Discussion: Husbands’ perception of their wives’ coping efficacy contributed
marginally to their wives’ adjustment, and the combination of WSEC and HSEC
mediated the relationship between functional status and wives’ adjustment, thus
positively impacting wives’ adjustment to cancer. Future research is needed to
determine the quality of the differences between HSEC and WSEC in order to
develop interventions to optimize the impact of these two relatively
independent perspectives on cancer outcomes.
