Background.

Unsupportive responses from relatives and spouses play a significant role in the psychological adjustment of breast cancer patients and their spouses, about whom little is known about them and their unsupportive responses predictors.

Objectives.

The aim of this study was to determine the predictors of perceived spouse unsupportive behaviours in women with breast cancer and their spouses.

Material and methods.

This is a cross-sectional study, in which 220 couples, including women with breast cancer and their spouses, participated in random samples in chemotherapy and cancer hospitals in Iran in 2020. In the present study, data was collected using a demographic checklist and the Unsupportive Partner Behaviour scale. The Kolmogorov-Smirnov test, ANOVA, independent t-Test, Hochberg post-hoc test and Chi-square test were used for group comparison. Univariate and multivariate linear regression methods were also used to assess the effect size.

Results.

Predictors of perceived unsupportive behaviours in women were: number of children (p = 0.047), life with relatives (p = 0.051), residence in suburbs (p = 0.006), marital status (p = 0.001), education and occupation of the spouse (p = 0.026), going to the hospital alone (p = 0.001), type of treatment received (p = 0.242), duration of diagnosis (p = 0.018) and type of residence (p = 0.051). Moreover, predictors of perceived unsupportive behaviours in men included: education and occupation of men (p = 0.035) and women (p = 0.050), type of treatment received (p = 0.050), employment of women (p = 0.030) and men (p = 0.009), residence in suburbs (p = 0.014), marital status (p = 0.019) and going to the hospital alone (p = 0.006).

Conclusions.

The variety of socio-economic, demographic and therapeutic factors were shown to be predictors of perceived unsupportive behaviours by spouses with breast cancer that can be modified by healthcare professionals in order to increase a couple’s mutual support.
