Оценка валидности РАS проведена на 454 больных достоверным РА, преимущественно жен. (85,2%), ср. возраст 51,3±11,3 лет, длительность заболевания 9,1±8,5 лет, 59,7% серопозитивных по ревматоидному фактору, большинство больных имели умеренную и высокую воспалительную активность заболевания (95,6%), II и III рентгенологическе стадии (44,7% и 27,8% соответственно), II (53,5%) и III ( 31,8%) функциональный класс.Конструктивная валидность индекса определялась путем расчета коэффициентов корреляций с «внешними критериями». Чувствительность оценивалась по критериям АСR у 285 больных через 6 мес проведения стандартной терапии. Надежность (воспроизводимость и внутреннее постоянство) оценивалась у 92 больных через 3 дня после поступления пациентов в стационар.</p></sec><sec><title>Результаты</title><p>Результаты. Оценка надежности индекса PAS тест-ретест анализом не выявила различий между первичной и повторной оценками пациентов, состояние которых не изменилось через 3 дня наблюдения (5,07 ± 1,27 балла и 5,17± 1,34 балла соответственно, p=0,45). Внутриклассовый коэффициент Кронбаха альфа был равен 0,95 (р&lt; 0,000001). При оценке конструктивной валидности выявлены умеренные взаимосвязи РАS c показателями воспалительной активности заболевания: длительностью утренней скованности (r=0,33,p&lt; 0,0000001), активностью заболевания по DAS28 (r=0,46, p&lt;0,001), числом болезненных (r = 0,39, p&lt; 0,000000) и воспаленных (r = 0,28, p&lt; 0,0002) суставов и слабые с показателями СОЭ и рентгенологической стадией заболевания (r=0,17,p&lt;0,0001). Корреляционные взаимосвязи индекса PAS с показателями КЖ, оцененными по всем шкалам общего опросника КЖ SF-36, имели значения от – 0,37 до – 0,58. При оценке чувствительности индекса к изменениям показано, что изменения PAS более чем на 0,22 балла соответствуют как минимум 20% улучшению состояния здоровья по критериям ACR.</p></sec><sec><title>Заключение</title><p>Заключение. Индекс PAS является надежным, валидным и чувствительным инструментом самооценки пациентом функционального состояния и может быть использован для динамической оценки больных в амбулаторной клинической практике и оценки эффективности терапии.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. To evaluate psychometric properties of Patient Activity Scale (PAS) index and possibility of its application for assessment of pt functional activity (PFA) and therapy efficacy in pts with rheumatoid arthritis (RA).</p></sec><sec><title>Material and methods</title><p>Material and methods. Validity assessment was performed on 454 pts with definite RA,mainly female (85,2%) with mean age 51,3±11,3 years, mean disease duration was 9,1±8,5 years, 59,7% of pts were seropositive on rheumatoid factor, most pts had moderate or high inflammatory activity of the disease (95,6%), II or III radiological stage ( 44,7% and 27,8% respectively, II (53,5%) or III (31,8%) functional class. Constructive validity of the index was assessed by calculation of coefficients of correlation with “external criteria”. Sensitivity was assessed with ACR criteria in 285 pts after 6 months of standard therapy. Reliability (reproducibility and internal constancy) were assessed in 92 pts in 3 days after admission.</p></sec><sec><title> </title><p> </p></sec><sec><title>Results</title><p>Results. Assessment of PAS reliability with test-retest analysis did not reveal differences between first and repeat examination of pts whose state had not change after 3 days (mean scores 5,07±1,27 and 5,17±1,34 respectively, p=0,45). Intra-class Cronbach alpha coefficient was 0,95 (p&lt;0,000001). Constructive validity assessment revealed moderate relationship of PFA with disease inflammatory activity measures: morning stiffness duration (r= 0,33, p&lt;0,0000001), DAS 28 value (r=46, p&lt;0,001), tender joint count (r=0,39, p&lt;0,0000001), swollen joint count (r=0,28, p&lt;0,0002) and weak relationship with ESR and radiological stage of the disease (r=0,17, p&lt;0,00001). PAS correlation relationships with quality of life measures assessed on all SF-36 scales varied from -0,37 to -0,58. Index sensitivity to changes assessment showed that PAS change exceeding 0,22 corresponded to at least 20% health improvement according to ACR criteria.</p></sec><sec><title>Conclusion</title><p>Conclusion. PAS is a reliable, valid and sensitive instrument of pt functional state self assessment and can be used for dynamic evaluation of pts state and treatment efficacy in outpatient practice</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>функциональная активность</kwd><kwd>ревматоидный артрит</kwd></kwd-group><kwd-group xml:lang="en"><kwd>quality of life</kwd><kwd>functional class</kwd><kwd>patient activity scale</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Олюнин Ю.А., Балабанова Р.М.
