Self-reported physical fitness (PF) provides an accurate measure of PF, specifically for young people. The Visual Analogue Scale (VAS) is one of the most used psychosocial measurement methods. The main arguments in favor of VAS are its ease of use and comprehension, particularly for less educated participants. There are some scales that assess self-perception of PF, but the VAS presented in this study covers a higher range of responses and a number of variables than other already validated measures.
The aim was to determine the concurrent validity of the Visual Analogue Fitness Perception Scale for Adolescents (FP VAS A) (Sub-study 1) and check its reliability (Sub-study 2).
Anthropometric and body composition measurements were performed, as well as PF tests (manual dynamometry, Course Navette, 4 × 10 m, and sit and reach). The International Fitness Scale (IFIS) and FP VAS A were used to assess self-reported PF.
Two sub-studies were carried out: in sub-study 1 a total of 67 students (26 males and 41 females aged 12-16 years) participated. The results showed a significant direct correlation between the level of PF and self-perception of PF (IFIS and FP VAS A), with the FP VAS A obtaining a higher correlation with PF ( = 0.444 to 0.666) than the IFIS and PF ( = 0.154 to 0.557). In sub-study 2 (test-retest of the FP VAS A), a total of 217 students (120 males and 97 females aged 12-17 years) participated. It showed a moderate reliability for all items; the intraclass correlation coefficient (ICC) was between 0.800 and 0.870, and kappa values ranged from 0.622 (endurance) to 0.458 (flexibility). In addition, Cronbach's α for the total was 0.860.
This study showed good validity and reliability for the FP VAS A in adolescents.
自我报告的体能（PF）是 PF 的一种准确测量方法，特别是对于年轻人而言。视觉模拟量表（VAS）是最常用的心理社会测量方法之一。支持 VAS 的主要论点是其易于使用和理解，特别是对于受教育程度较低的参与者而言。有一些量表可以评估自我感知的 PF，但本研究中提出的 VAS 比其他已经验证的量表涵盖了更高范围的反应和更多变量。
目的是确定青少年视觉模拟体能感知量表（FP VAS A）的同时效度（子研究 1）并检查其可靠性（子研究 2）。
进行了人体测量和身体成分测量，以及 PF 测试（手动测力计、Course Navette、4×10 m 和坐立伸展）。使用国际体能量表（IFIS）和 FP VAS A 评估自我报告的 PF。
进行了两项子研究：在子研究 1 中，共有 67 名学生（26 名男性和 41 名女性，年龄为 12-16 岁）参加。结果表明，PF 水平与自我感知的 PF（IFIS 和 FP VAS A）之间存在显著的直接相关性，其中 FP VAS A 与 PF 的相关性更高（=0.444 至 0.666），而 IFIS 和 PF 的相关性较低（=0.154 至 0.557）。在子研究 2（FP VAS A 的测试-重测）中，共有 217 名学生（120 名男性和 97 名女性，年龄为 12-17 岁）参加。它显示出所有项目的中等可靠性；组内相关系数（ICC）在 0.800 至 0.870 之间，kappa 值范围为 0.622（耐力）至 0.458（柔韧性）。此外，总 Cronbach's α 为 0.860。
本研究表明，FP VAS A 在青少年中具有良好的有效性和可靠性。
