Background. Currently, psychological knowledge integrates theories on codependent behavior, advancing our understanding of this phenomenon. However, empirical research is lacking to understand its specific manifestations in relation to different types of addiction.

Objective. To identify the features of self-attitude and reflection in codependent women.

Design. The study included 233 women (ages 18–70), including 102 in relationships with a person addicted to alcohol, drugs, or suffering from a non-chemical addiction). The study was conducted using the following methods: Self-Attitude Questionnaire (Stolin & Panteleev, 1988); Differential Type of Reflection Questionnaire (Leontiev, 2009); and Codependency Self-Inventory Scale (CSIS; Weinhold & Weinhold, 1989; translated by A. G. Cheslavskaya, 2002).

Results. Significant differences were observed in self-attitude and reflection. Women with high codependency have lower self-esteem and tend to underestimate their abilities, compared to the control group. They also exhibit a lower sense of control over their lives, lower self-consistency; they tend to focus on their weaknesses and shortcomings and are more inclined to self-blame. Quasi-reflexivity is more common in codependent women who have relationships with non-chemical addicts or do not identify an addict in their lives.

Conclusion. There are significant differences in self-attitude and reflection between the control group and subgroups of women in relationships with different types of addicts; the same differences were observed in comparison of women with low and high codependency levels. The study contributes to a better understanding of the psychological mechanisms underlying codependent behavior in women and has implications for future research and clinical practice.

Background. It is known that some genes regulate neurochemical metabolism, and their polymorphisms affect cognitive performance, including the ability to categorize emotionally significant information.

Objective. The aim of our study was to analyze the recognition of emotional and neutral visual scenes in carriers of different polymorphic variants of the MAOA, COMT, DRD4, and 5HT2A genes.

Design. The study sample consisted of 87 university students (Caucasians, women 63%, average age 20.4±2.6 years). The genotypes of the COMT, 5HT2A, and DRD4 genes were determined by polymerase chain reaction. Agarose gel electrophoresis was used to determine the number of tandem repeats of the MAOA gene. Three hundred sixty (360) photographic images of scenes of different emotional valence (positive, negative, and neutral – 120 images for each category) were used as stimuli. These images were classified by expert assessments. The images were presented in a random sequence. The exposure time was 700 ms. The research participants were asked to determine the emotional valence of each scene.

Results. We found that only the COMT gene genotype affected the recognition of emotional and neutral visual scenes. Carriers of the COMT Val/Val genotype, which causes dopamine to stay in the synaptic space for a shorter time, are better in recognizing and demonstrate higher sensitivity to the emotional content of scenes. Carriers of the Val/Met genotype demonstrated the worst ability to differentiate the emotional valence of visual scenes.

Conclusion. This study has shown that the length of stay of monoamines in the synaptic space regulated by the COMT gene affects the recognition of emotional visual information.
