[An associations of possible genetic risk markers for Internet addiction with childhood trauma experience and personality traits in young adults : preliminary results]. / Svyaz' geneticheskikh markerov riska razvitiya internet-zavisimosti s detskim psikhotravmiruyushchim opytom i lichnostnymi osobennostyami u molodykh vzroslykh: predvaritel'nye rezul'taty.

OBJECTIVE: To study was to test an associations of the preliminary genetic risk markers for Internet addiction (IA) with clinical, psychological and personality characteristics, taking into account the childhood traumatic experience, in 44 IA persons compared with 120 healthy individuals. MATERIAL AND METHODS: The study included 164 participants: 44 individuals with IZ (group IZ), male and female, aged 16 to 30 years in the absence of diagnoses of mental health problems. diseases from rubrics F00-09 and F20-29 (ICD-10) and 120 healthy (control group). RESULTS AND CONCLUSION: We have found an associations of the preliminary IA genetic risk markers with some personality traits and behavioral characteristics (TCI-125, TIPI) and with the childhood trauma experience (ACE IQ, CTQ), both for healthy individuals and to a greater extent for IA individuals, that may suggests the possible effects of the gene-environment interaction on a risk of developing IA. The data obtained on the structure of associations between IA genetic risk markers and individual psychological characteristics under the significant influence of the childhood trauma experience allow us to proceed with the construction of models for IA risk prediction taking into account the "gene - environment" interactions.

[The relationship of psychosocial well-being of patients with schizophrenia with clinical, socio-demographic and neurocognitive characteristics]. / Svyaz' psikhosotsial'nogo blagopoluchiya bol'nykh shizofreniei s klinicheskimi, sotsial'no-demograficheskimi i neirokognitivnymi kharakteristikami.

OBJECTIVE: To explore the relationship between the indicators of quality of life (QOL) and social functioning (SF) of patients with schizophrenia with clinical and socio-demographic characteristics, indicators of cognitive functions and the severity of disease symptoms, using mathematical modeling methods. MATERIAL AND METHODS: The sample consisted of 300 patients with paranoid schizophrenia (aged 18-50 years, disease duration at least 5 years; total PANSS score <120). Clinical-psychopathological, psychometric and mathematical methods were used. A mathematical model based on the construct developed by the authors called the «Disease Burden Factor¼ (Factor «B¼) was utilized. RESULTS AND CONCLUSION: Statistically significant correlations of factor "B" with age, the time of disease onset, seeking psychiatric help and diagnosis, the length of hospital admissions in the past 12 months and PANSS and BACS scores were established. Factor «B¼ clusters of «prosperous¼ and «dysfunctional¼ patients, significantly differing in the frequency of exacerbations of the disease, its total duration, and indicators of QOL-SM, PSP, PANSS, BACS, were distinguished. The conclusion about the reliability and sensitivity of a new toolbox - Factor «B¼ for exploring the mutual influence of heterogeneous factors affecting the trajectory of patients with schizophrenia was made.
