Chronic fatigue syndrome (CFS) has a major impact on functioning. However, no validated measures of functioning for this population exist.
We aimed to establish the psychometric properties of the 5-item School and Social Adjustment Scale (SSAS) and the 10-item Physical Functioning Subscale of the SF-36 in adolescents with CFS.
Measures were completed by adolescents with CFS (n = 121).
For the Physical Functioning Subscale, a 2-factor solution provided a close fit to the data. Internal consistency was satisfactory. For the SSAS, a 1-factor solution provided an adequate fit to the data. The internal consistency was satisfactory. Inter-item and item-total correlations did not indicate any problematic items and functioning scores were moderately correlated with other measures of disability, providing evidence of construct validity.
Both measures were found to be reliable and valid and provide brief measures for assessing these important outcomes. The Physical Functioning Subscale can be used as two subscales in adolescents with CFS.
慢性疲劳综合征（CFS）对功能有重大影响。然而，针对该人群，目前尚没有经过验证的功能评估方法。
我们旨在确定 5 项学校和社会适应量表（SSAS）和 SF-36 的 10 项身体功能子量表在青少年 CFS 患者中的心理测量特性。
通过 CFS 青少年（n=121）完成这些措施。
对于身体功能子量表，双因素解决方案提供了与数据的紧密拟合。内部一致性是令人满意的。对于 SSAS，单因素解决方案提供了与数据的适当拟合。内部一致性是令人满意的。各项目之间和项目总分之间的相关性表明没有任何有问题的项目，并且功能评分与其他残疾评估方法中度相关，提供了结构有效性的证据。
这两种方法都被发现是可靠和有效的，并提供了评估这些重要结果的简短方法。身体功能子量表可在青少年 CFS 患者中作为两个子量表使用。
