Victims of childhood maltreatment often experience lower mental health and psychological well-being in adulthood. (Huang et al., 2021) Various factors define adults' sense of well-being, and in this regard, the Perma well-being model presents these factors. The experience of childhood maltreatment can overshadow a person's sense of psychological well-being by distorting the defining characteristics of the Perma model. Based on past research, the trait of mindfulness in people (the ability to experience the here and now) can play a mediating role in this relationship due to its connection with each of the factors of the Perma model and on the other hand due to its connection with childhood abuse; Therefore, this research aims to determine the mediating role of mindfulness on the predictive relationship between childhood maltreatment and the sense of psychological well-being of the Permamodel. Correlation matrix and structural equations will be tested. Sampling by non-probability method and available in people aged 25 to 55 is estimated based on Klein's formula with a minimum number of330 and a maximum of 990. Determining this connection can lead to a new understanding of the relationship between childhood traumas and the good life so that adults can bring themselves closer to a good life by repairing the disorder in their consciousness
