The aim of this study was to demonstrate the validity and reliability of the WFIRS-S-TR, Turkish version of the Weiss Functional Impairment Rating Scale-Self Report form.
The study comprised two groups of participants of 15-18 years of age, one consisting of 35 children diagnosed with attention deficit and hyperativity disorder (ADHD) based on the DSM-IV criteria and the other, 510 healthy volunteers attending high school. Apart from the WFIRS-S-TR, the Health Questionnaire for Children and Adolescents (KIDSCREEN-10 Index) which is a general quality of life and functionality measurement instrument, was used to check the concurrent validity of the WFIRS-S-TR.
The Cronbach's alpha coefficient for the total scale was 0.939. The test-retest reliability assessed by repeated measurements two weeks apart gave a high correlation between the results (r=0.804, p<0.0001). Total mean score of the WFIRS-S-TR showed significant correlation with the KIDSCREEN-10 Index total mean score (r= -0.467, p<0.0001). Confirmatory factor analysis was carried out for the construct validity of the WFIRS-S-TR. The RMSEA and the CFI values were found to be 0.065 and 0.68, respectively.
The WFIRS-S-TR can be used as a valid and reliable tool both in clinical practice and for research purposes.
本研究旨在验证 WFIRS-S-TR 的有效性和可靠性，WFIRS-S-TR 为 Weiss 功能障碍评定量表自评式土耳其语版本。
本研究纳入了两个年龄在 15-18 岁的参与者组，一组为 35 名符合 DSM-IV 标准的注意力缺陷多动障碍（ADHD）儿童，另一组为 510 名在高中就读的健康志愿者。除 WFIRS-S-TR 外，还使用儿童青少年健康问卷（KIDSCREEN-10 指数）来评估 WFIRS-S-TR 的同时效度，该问卷是一种用于测量一般生活质量和功能的工具。
总量表的克朗巴赫 α 系数为 0.939。两周后通过重复测量评估的重测信度显示结果之间具有高度相关性（r=0.804，p<0.0001）。WFIRS-S-TR 的总均数得分与 KIDSCREEN-10 指数的总均数得分呈显著相关（r=-0.467，p<0.0001）。进行了 WFIRS-S-TR 的结构效度验证性因子分析。RMSEA 和 CFI 值分别为 0.065 和 0.68。
WFIRS-S-TR 可在临床实践和研究中作为有效且可靠的工具使用。
