Effectiveness of a couple-based intervention on sexuality and intimacy among women in active cancer treatment: A quasi-experimental study.
2021
Purpose To evaluate the effectiveness of a strenghts-oriented therapeutic conversation intervention on confidence about how illness beliefs affect sexuality and intimacy and on perceived relationship quality among women in active cancer treatment and their partners. Methods A quasi-experimental single-group pre-post-follow-up design was used. Women in active cancer treatment and their intimate partners were randomly assigned to a nurse-managed couple-based intervention (experimental group, n=30 couples) or wait-list (delayed intervention) control group (n=27 couples) plus 4 additional couples who pilot tested feasibility of the intervention, prior to the RCT. However, baseline differences in demographic and clinical variables prevented comparisons between groups. Therefore, a repeated-one-group pre-post test setup was used, comparing women with cancer and their partners over three time points. The intervention consisted of three Couple-Strengths-Oriented Therapeutic Conversations (CO-SOTC) sessions. The participants also had access to web-based evidence-based educational information. Data were collected before intervention (T1, baseline), one to two weeks post-intervention (T2), and after a follow-up session at three months (T3). Data from 60 couples (N=120) were analyzed. Results Significant differences were observed, for both women and intimate partners, over time in more confidence about how illness beliefs affected sexuality and intimacy (T1 versus T2, and T1 versus T3), and increased overall quality of the relationship (T1 versus T2, and T1 versus T3). No differences were found between dyad members’ scores on illness beliefs or relationship quality at any time point. Conclusions The CO-SOTC intervention was effective in supporting sexual adjustment among women in cancer treatment and their intimate partners.
