Aim: To develop a programme of psychocorrectional assistance for women in codependent marital relationships and to evaluate its effectiveness Materials and Methods: The study involved 48 women aged 25–45 years who were in codependent marital relationships. The basic course of psychocorrec tional therapy consisted of ten sessions. The effectiveness of the psychocorrectional programme was assessed using the following psychodiagnostic methods: the Codependency Self-Evaluation Scale (CSIS), the Codependency Level Measurement Scale (D. Spann and D. Fisher), Self-Evaluation of Emotional States (A. Wessman, D. Ricks), Self-Evaluation of Mental States (H. Eysenck), and Definition of Self-Evaluation (S. Kovalev). Results: As a result of the psychocorrectional sessions, the general mental state of the women improved. They reported feeling more energetic, confident calm, and relaxed. Stabilisation of the new self-position in everyday and partner-related situations, as well as a strengthening of decision-making quality in relationships, was observed in 42 (87.5%) participants during long-term follow-up. Conclusions: The developed comprehensive psychocorrectional programme demonstrated high effectiveness both in short- and medium-term outcomes and in the long term. This indicates the achievement of a positive personal transformation among the participants, serzzving as a psychoprophylactic factor against the risk of developing further codependent relationships. Future research is planned to focus on developing a psychocorrectional programme for men in codependent relationships and evaluating its effectiveness.
