Gender-Based violence is a worldwide persisting phenomenon: during their lifetime, 30% of women have experienced sexual and/or physical violence. The literature has investigated for several years the association between abuse and possible psychiatric and psychological consequences which may occur even after many years. The most common consequences involve mood and stress disorders (e.g., depression and PTSD). These disorders seem to have secondary long-term effects, such as decision-making and cognitive function impairments. Therefore, the present literature synthesis aimed to investigate whether and how the decision-making capacities of individuals experiencing violence can change because of abuse. We conducted a thematic synthesis using PRISMA guidelines: through a double-blind procedure, 4599 studies were screened; a total of 46 studies were selected for full-text reading, which was reduced to 13 by excluding papers with a wrong focus. To better understand the results of the thematic synthesis, two main focuses have been identified: “leave or stay decision making” and “multifactorial dimensions of decision making”. Results showed that decision-making is an important process in avoiding secondary victimization.
