Abstract

Introduction: The aim of this study was to evaluate the effect of individual therapy (PLISSIT Model) versus group therapy (Sexual Health Model) on the quality of life of Iranian women with breast cancer. Methods: Three-arm parallel-group randomized controlled trial conducted on 75 women with breast cancer attended to Mehraneh Charity Center in Zanjan in 2015�2016. The participants were allocated into three groups of the PLISSIT model, the SHM, and a routine care group. The study tool included demographic checklist and quality of life questionnaire, which completed by all groups at baseline, 6, and 12 weeks follow-ups. Data were analyzed using chi-square, ANOVA, Kruskal�Wallis, and Friedman tests. Results: At the baseline, there were no significant differences in dimensions of quality of life between the three groups. Also, at 6 and 12 weeks follow-ups, almost all dimensions of the quality of life in all groups improved significantly (all Ps < 0.001). However, there were no significant differences between the three groups at these phases. Conclusion: The study revealed that both the PLISSIT Model and grouped SHM have similar effects on improving the quality of life of women. There was not enough evidence of the superiority of one model over another. © 2021, Springer Science+Business Media, LLC, part of Springer Nature.
