The proposed work studies the psychological well-being and premorbid personality traits in adolescents with homosexual and bisexual orientation. The study involved 70 adolescents aged 12-16 years who considered themselves homosexuals / bisexuals. Research methods: scale of self-efficacy; five-Factor personality questionnaire; scale of psychological well-being of Riff; scale of self-efficacy; test of dispositional optimism. As a result of the study, it was found that the surveyed adolescents are not characterized by a very high level of psychological well-being and are characterized by such features as high neuroticism, developed expressiveness and high attachment. Medium and low levels of optimism and self-efficacy prevail. The practical significance of the study is that the data obtained by us can be used to further study the personal determinants of subjective well-being in persons with homosexual and bisexual orientation.
