Results of a questionnaire, based on likely scenarios applied to 267 women, show that women in a relationship invest more time/days in a relationship than those who are not in a relationship. Also,  an effect of scenario and of relationship status on sunk cost effect were found. Women spend more time in a non-violent scenario; also, they spend more time in a scenario of psychological violence than in one of sexual or physical violence. These results suggest that being in a relationship enhance the likelihood of committing sunk cost effect; prior investments in a relationship acquire more value for individuals in a current relationship where those efforts exist naturally.</p>}, number={3}, journal={Revista Interamericana de Psicología/Interamerican Journal of Psychology}, author={Nunes-Costa, Rui and Serra, Mafalda and Sousa, Tânia and Leite, Ângela}, year={2020}, month={Mar.}, pages={445–459} }
