Background:

The Hospital for Special Surgery Pediatric Functional Activity Brief Scale (HSS Pedi-FABS) is a specifically designed scoring system for children and has been translated into several languages. However, to date, no validated Japanese version of this scoring system is available.

Purpose:

To translate the HSS Pedi-FABS into Japanese and assess its reliability and validity.

Study Design:

Cohort study (diagnosis); Level of evidence, 2.

Methods:

The HSS Pedi-FABS was translated into Japanese and back-translated into English to confirm the appropriateness of the translation. A total of 764 children aged 9 to 15 years participated in the validation study. The participants answered the Japanese version of the HSS Pedi-FABS along with 2 other questionnaires in Japanese (the Physical Activity Questionnaire for Older Children [PAQ-C] and the physical activity questionnaire of the World Health Organization’s Health Behavior in School-aged Children [HBSC PAQ]). At 1 month after the first assessment, the children answered the Japanese version of the HSS Pedi-FABS again. We evaluated reliability using the Cronbach alpha and the intraclass correlation coefficient. Validity was evaluated by quantifying floor and ceiling effects, correlations between the HSS Pedi-FABS and the PAQ-C, the HSS Pedi-FABS discrepancy between active and inactive groups divided by the HBSC PAQ, and correlation between the HSS Pedi-FABS and body mass index.

Results:

HSS Pedi-FABS scores were slightly but significantly higher in male participants (mean = 16.7) than in female participants (mean = 13.2). The Cronbach alpha coefficient was .90, and the intraclass correlation coefficient value was 0.90, indicating excellent internal consistency and test-retest reliability, respectively. No floor (2.6%) or ceiling effect (1.0%) was observed. The HSS Pedi-FABS was significantly correlated with the PAQ-C (r = 0.70). The active group demonstrated a significantly higher score on the HSS Pedi-FABS (mean = 18.9) than did the inactive group (mean = 11.2). In terms of discriminative validity, the HSS Pedi-FABS was not correlated with body mass index (r = –0.15).

Conclusion:

The Japanese version of the HSS Pedi-FABS demonstrated appropriate reliability and validity, indicating that it is a useful tool to assess physical activity levels in Japanese children.

日版特殊外科医院儿科功能活动简表（HSS Pedi-FABS）的跨文化适应与验证

背景：

特殊外科医院儿科功能活动简要量表 (HSS Pedi-FABS) 是专门为儿童设计的评分系统，已被翻译成多种语言。然而，迄今为止，该评分系统还没有经过验证的日文版本可用。

目的：

将 HSS Pedi-FABS 翻译成日文并评估其信度和效度。

学习规划：

队列研究（诊断）；证据水平，2。

方法：

HSS Pedi-FABS 被翻译成日文并回译成英文，以确认翻译的适当性。共有 764 名 9 至 15 岁的儿童参加了验证研究。参与者回答了日语版 HSS Pedi-FABS 以及另外 2 份日语问卷（大龄儿童体力活动问卷 [PAQ-C] 和世界卫生组织学龄儿童健康行为体力活动问卷 [ HBSC PAQ]）。第一次评估后1个月，孩子们再次回答了日语版的HSS Pedi-FABS。我们使用 Cronbach α 和组内相关系数评估可靠性。通过量化地板和天花板效应、HSS Pedi-FABS 和 PAQ-C 之间的相关性来评估有效性，

结果：

男性参与者（平均 = 16.7）的 HSS Pedi-FABS 分数略高于女性参与者（平均 = 13.2）。Cronbach α 系数为 0.90，组内相关系数值为 0.90，分别表明良好的内部一致性和重测信度。没有观察到地板效应（2.6%）或天花板效应（1.0%）。HSS Pedi-FABS 与 PAQ-C 显着相关（r = 0.70）。活动组在 HSS Pedi-FABS 上的得分（平均值 = 18.9）明显高于非活动组（平均值 = 11.2）。在区分效度方面，HSS Pedi-FABS 与体重指数不相关（r = –0.15）。

结论：

日文版 HSS Pedi-FABS 表现出适当的信度和效度，表明它是评估日本儿童体力活动水平的有用工具。
