Using the World Health Organization's classification system of the consequences of disease, this study sought to examine the impact of physical and psychological impairment variables, beyond that contributed by social, demographic, and disease variables, on the functional disability of a rheumatoid arthritis (RA) sample. Data collected during an acute episode were used to predict concurrent and future disability status.
A secondary data analysis of 85 adults hospitalized for exacerbations in arthritis was undertaken. Disability was assessed with the Health Assessment Questionnaire. Physical impairment was measured with the Keitel Function Test and Pain Analog Scales, and psychological impairment was measured with the Center for Epidemiologic Studies Depression Scale and the Perceived Self-Efficacy Scale for People with Arthritis.
Our findings indicated that physical impairment, demographic, and disease variables accounted for 64% of the explained variance in disability during the concurrent episode. Psychological impairment as well as demographic and disease variables accounted for 49% of the explained variance in future disability status.
The combined influence of demographic characteristics and the consequences of the pathology of RA experienced as physical and psychological impairments contributed differentially to disability during concurrent and future time periods.
本研究采用世界卫生组织的疾病后果分类系统，旨在检验身体和心理损伤变量对类风湿关节炎（RA）样本功能残疾的影响，这种影响超出了社会、人口统计学和疾病变量所造成的影响。在急性发作期间收集的数据用于预测同时期和未来的残疾状况。
对85名因关节炎加重而住院的成年人进行了二次数据分析。使用健康评估问卷评估残疾情况。通过凯特尔功能测试和疼痛模拟量表测量身体损伤，通过流行病学研究中心抑郁量表和关节炎患者自我效能感量表测量心理损伤。
我们的研究结果表明，身体损伤、人口统计学和疾病变量占同时期残疾状况中可解释变异的64%。心理损伤以及人口统计学和疾病变量占未来残疾状况中可解释变异的49%。
人口统计学特征以及类风湿关节炎病理后果所造成的身体和心理损伤的综合影响，在同时期和未来时间段对残疾的影响有所不同。
