Two studies examined the reliability and validity of the Self-Assessment of Occupational Functioning (SAOF), a 23-item self-assessment of perceptions of strengths, and weaknesses relative to occupational functioning, grounded in the Model of Human Occupation.
The first study examined the test-retest reliability of the SAOF, and involved 37 college students without disabilities who completed the SAOF twice. The second study, which involved 39 young persons hospitalized with psychiatric disorders, examined internal consistency reliability of the SAOF, and examined correlations between SAOF scores and composite scores on the Self-Perception Profile, a widely used measure of perceived competence. In addition, data from both studies were combined to examine the ability of the SAOF to discriminate between the college students without disabilities and the young persons with psychiatric disorders.
Kappa and intraclass correlation coefficients (ICCs) were used to examine test-retest reliability and Cronbach's alpha was used to examine internal consistency. Acceptable levels of test-retest (ICCs) and internal consistency (Cronbach's alpha) reliability were found for the subscale and total scores of the SAOF. However, test-retest reliability (kappa) was lower than desirable for many of the individual SAOF items. The young persons with psychiatric disorders had lower item, subscale, and total scores on the SAOF than did the college students without disabilities. In addition, a discriminant analysis predicting group membership (college students without disability vs. young persons with psychiatric disorder) correctly classified 76.6% of the participants based on the four subscale scores of the SAOF.
The SAOF has the potential to be a reliable and valid clinical assessment; however, additional research is needed.
两项研究检验了职业功能自我评估量表（SAOF）的信效度。SAOF是一份包含23个条目的自我评估量表，基于人类作业模式，用于评估与职业功能相关的优势和劣势感知。
第一项研究检验了SAOF的重测信度，37名无残疾的大学生完成了两次SAOF测试。第二项研究纳入了39名因精神障碍住院的年轻人，检验了SAOF的内部一致性信度，并考察了SAOF得分与自我感知概况综合得分之间的相关性，自我感知概况是一种广泛使用的感知能力测量工具。此外，将两项研究的数据合并，以检验SAOF区分无残疾大学生和有精神障碍年轻人的能力。
使用卡方系数和组内相关系数（ICC）检验重测信度，使用克朗巴哈α系数检验内部一致性。SAOF分量表和总分的重测信度（ICC）和内部一致性信度（克朗巴哈α系数）达到可接受水平。然而，许多SAOF单个条目重测信度（卡方系数）低于理想水平。有精神障碍的年轻人在SAOF上的条目、分量表和总分低于无残疾的大学生。此外，一项预测组成员身份（无残疾大学生与有精神障碍年轻人）的判别分析基于SAOF的四个分量表得分正确分类了76.6%的参与者。
SAOF有可能成为一种可靠且有效的临床评估工具；然而，还需要进一步的研究。
