Introduction. This article is devoted to research the level and types of aggression, expressiveness of legitimized aggression (LA), conflict-handling behavior, level of the personality anxiety, level of depression and formal-dynamic properties of individuality (temperamental characteristics) of Russian women-carriers of different HTR2A, COMT, BDNF genes diplotypes. These genes are associated with neurotransmitters systems, neuroplasticity and it is important – to discover their correlations with the psychological characteristics; it was the aim of our research.
The hypothesis of research: different combinations of genotypes of neurotransmitters systems and neuroplasticity genes (HTR2A, COMT, BDNF), probably, associated with the various psychological characteristics of women.
Materials and methods. Genetic stage: buccal epithelium sampling, PCR (“BiReT”, Russia).
Psychological stage: Buss-Durkee Hostility Inventory, Thomas conflict-handling behavior Inventory, Questionnaire of formal-dynamic individuality properties, Beck Depression Inventory, State-Trait Anxiety Inventory, legitimized aggression Inventory.
Observers: 68 Russian women.
Explored diplotypes: BDNF Val/Val + COMT Val/Met + TR2 A/G + TR3 T/C (№1), BDNF Val/Val + COMT Val/Val + TR2 A/G + TR3 T/C (№2), BDNF Val/Val + COMT Val/Met + TR2 A/A+ TR3 T/T (№3), BDNF Val/Met + Val/Met + TR2 G/G + TR3 C/C (№4).
Statistical data processing: factorial ANOVA, p≤0,05.
Results.
Based on the analysis, we find the psychological characteristics of Russian women with different diplotypes of the genes studied. Carriers of diplotype №1 have the following features: a significantly lower level of offense (M=2.7, p=0.03), a low level of preference for avoidance conflict strategies (M=3.8, p=0.03), a low level of LA (M=56.6, p=0.02), including - in politics (M=32.1, p=0.03) and in personal experience (M=24.3, p=0.006). Members of this group have a high level of personal anxiety (M=50, p=0.02).
Women with a diplotype №2 have opposite characteristics: a higher level of offense (M=5.2, p=0.03), avoidance of conflict (M=6.8, p=0.04); high integral index of LA (M=82, p=0.02), including - in politics (M=49.4, p=0.03), in personal experience (M=39, p=0.006), in sports (M=15.6, p=0.03).
Girls with this diplotype have lower motor mobility (M=23.2, p=0.01) and motor speed (M=28.6, p=0.01), but more high level of communicative emotionality (M=38.2, p=0.03).
Russian women with diplotype №3 have a higher level of inclination to cooperate in the conflict (M=7, p=0.03), low integral level of LA (M=56.4, p=0.02), including LA in politics (M=33.6, p=0.04) and in sports (M=9.6, p=0.04). The high motor mobility (M=33,3, p=0,01) and the low level of communicative plasticity (M=26,3, p=0,05) can be individually attributed to the formal-dynamic properties of this women. Women with diplotype №4 have a high level of inclination to cooperate in the conflict (M=7, p=0.04), compared with the carriers of other diplotypes. A higher level of avoidance of conflict is inherent in women with diplotype (M=6.9, p=0.03), The formal-dynamic properties of this women: high level of communicative plasticity (M=32, p=0,05), high motor speed (M=36,6, p=0,01).
There were no significant differences in the level of depression in the study sample. Conclusion. Based on the results obtained, we can conclude that the hypothesis was confirmed.
