The Weiss Functional Impairment Rating Scale-Self-Report Form (WFIRS-S) was developed as a measure of functional impairment in adolescents and adults with ADHD. This study reports the psychometric properties of the Persian version of the WFIRS-S in a sample of normal Iranian adolescents.
Internal consistency and factor structure of the WFIRS-S were tested on a sample of 386 students (Grades 7-12). The test-retest reliability and the convergent validity of the WFIRS-S were evaluated by using two different subsamples including 50 and 100 students, respectively.
The Cronbach's alpha values were between .72 and .94 for the WFIRS-S subdomains and total scale. The test-retest reliability was .80 for the total scale. The WFIRS-S subdomains had moderate to high significant correlations with the Pediatric Quality of Life total scale.
The Persian version of the WFIRS-S has acceptable psychometric properties and could be used as a functional impairment assessment for adolescents.
韦斯功能损害评定量表自我报告表（WFIRS-S）是作为评估患有注意力缺陷多动障碍（ADHD）的青少年和成人功能损害的一种工具而编制的。本研究报告了伊朗正常青少年样本中波斯语版WFIRS-S的心理测量特性。
对386名学生（7至12年级）样本测试了WFIRS-S的内部一致性和因子结构。分别使用包括50名和100名学生的两个不同子样本评估了WFIRS-S的重测信度和收敛效度。
WFIRS-S子领域和总量表的克朗巴赫α值在0.72至0.94之间。总量表的重测信度为0.80。WFIRS-S子领域与儿童生活质量总量表具有中度至高度显著相关性。
波斯语版的WFIRS-S具有可接受的心理测量特性，可作为青少年功能损害评估工具。
