The present study aimed to investigate the effectiveness of Mindfulness-Based Cognitive Therapy (MBCT) in reducing depression and suicidal thoughts, as well as improving sleep quality and self-esteem in women with a history of domestic violence.<br> <strong>Materials and Methods</strong>: The study employed a quasi-experimental design with pretest&ndash;posttest and follow-up phases, including a control group. A total of 45 women with a history of domestic violence were selected using purposive sampling and randomly assigned to experimental and control groups. The experimental group received eight weekly MBCT sessions, while the control group received no intervention. Data were collected using the Beck Depression Inventory (1961), the Beck Scale for Suicidal Ideation (1979), the Pittsburgh Sleep Quality Index by Buysse et al. (1989), and the Rosenberg Self-Esteem Scale (1965), and analyzed using multivariate analysis of covariance (MANCOVA).<br> <strong>Results</strong>: The results indicated that the intervention significantly reduced depression and suicidal ideation and improved sleep quality and self-esteem in both the posttest and follow-up phases (p<0.01).<br> <strong>Conclusions</strong>: These findings underscore the effectiveness of MBCT in alleviating the psychological consequences of domestic violence and support its application in support services for affected women.</span></span> Depression, Domestic violence, Mindfulness-based cognitive therapy, Self-esteem, Sleep quality, Suicidal ideation 82 88 http://ajnpp.umsha.ac.ir/browse.php?a_code=A-10-1580-1&slc_lang=en&sid=1 Najmeh Shahrashoob najmeshahrashoob2660@gmail.com 10031947532846008530 0009-0004-8851-490X No Department of Psychology, Shi.C., Islamic Azad University, Shiraz, Iran.
