Blokhin Russian Cancer Research Center, Ministry of Health of Russia. We assessed the association between the quality of life and psychological characteristics of patients – coping strategies and personal resources. We used a general questionnaire for assessing patients’ quality of life (The Medical Outcomes Study Short Form 36 Items Health Survey) and special questionnaires for cancer patients (Quality of Life Questionnaire – Core 30, QLQ-C30), patients with tumor lesions to the spine (Spine Oncology Study Group Outcomes Questionnaire, SOSG OQ), and psychodiagnostic methods, such as Ways of Coping, Big Five, and Life-meaning Orientations. We have identified an association between the quality of life and all parameters of psychodiagnostic questionnaires, better quality of life correlated with more pronounced psychological characteristics reflecting the maturity of the individual (internality, activity, presence of meaningful goals, ability to seek social support, etc.). Lower personal maturity and poorer constructive coping strategies were associated with worse somatic symptoms and their impact on the quality of life.</p></abstract><trans-abstract xml:lang="ru"><p>В статье представлены результаты исследования основных параметров качества жизни 62 пациентов (35,5 % – мужчины, 64,5 % – женщины; средний возраст – 55 лет), имеющих опухолевые поражения различных отделов позвоночника и находящихся на лечении в отделении вертебральной хирургии Национального медицинского исследовательского центра онкологии им. Н.Н. Блохина Минздрава России. Изучена взаимосвязь качества жизни с психологическими характеристиками больных – стратегиями и личностными ресурсами совладающего поведения (копинга). В исследовании использованы общий опросник качества жизни пациента (The Medical Outcomes Study Short Form 36 Items Health Survey), специализированные опросники качества жизни при онкологической патологии (Quality of Life Questionnare – Core 30, QLQ-C30), опухолевом поражении позвоночника (Spine Oncology Study Group Outcomes Questionnaire, SOSG OQ), а также психодиагностические методики: ≪Способы совладающего поведения≫, ≪Большая пятерка≫ (Big Five) и ≪Смысложизненные ориентации≫. Выявлена взаимосвязь параметров качества жизни пациентов со всеми показателями психодиагностических опросников. Лучшие показатели качества жизни соответствовали большей выраженности психологических характеристик, отражающих зрелость личности (интернальность, активность, наличие осмысленных целей, способность к обращению за социальной поддержкой и др.). Снижение показателей зрелости личности и конструктивных стратегий копинга сопровождается усилением соматической симптоматики и ее влияния на качество жизни больных.</p></trans-abstract><kwd-group xml:lang="en"><kwd>spine tumors</kwd><kwd>surgical treatment</kwd><kwd>quality of life</kwd><kwd>coping strategies</kwd><kwd>personal resources</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>опухоли позвоночника</kwd><kwd>хирургическое лечение</kwd><kwd>качество жизни</kwd><kwd>копинг-стратегии</kwd><kwd>личностные ресурсы</kwd></kwd-group><funding-group><funding-statement xml:lang="en">The study was funded by the Russian Foundation for Basic Research grant No. 19-013-00154 A.</funding-statement><funding-statement xml:lang="ru">Исследование выполнено на средства гранта Российского фонда фундаментальных исследований № 19-013-00154 А.</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Psychological diagnosis of coping with stress behavior.
