Abstract：
The main objective of this person-centred study was to identify profiles of actual and perceived physical fitness among a sample of youth with intellectual disabilities (ID). Participants were 377 youth (60.4% boys) with mild (49.6%) to moderate (50.4%) ID recruited in Australia and Canada. Latent profile analyses revealed five profiles: (1) Underestimation of Average Physical Fitness (5.5% of the sample); (2) Moderate Overestimation of Low Physical Fitness (17.7%), (3) Moderate Underestimation of Average Physical Fitness (31.3%); (4) High Overestimation of Average Physical Fitness (28.3%); and (5) Moderate Underestimation of High Physical Fitness with an Accurate Estimation of Average Flexibility (17.2%). Profiles 1, 2, and 3 relatives to Profiles 4 and 5 included younger participants, more participants with moderate levels of ID, and participants with a higher body mass index. Additionally, profiles 1 and 3 also included a higher proportion of youth pursuing externally-driven motives and less frequently involved in sports outside of the school. In sum, our findings showed that the tendency of youth with ID to rely on upward or downward-lateral social comparisons may have resulted in a depreciation or overestimation of their low levels of physical fitness.
摘要：
这项以人为中心的研究的主要目的是确定智障青年（ID）样本中实际和感知的身体健康状况。参与者是377名青年（60.4％的男孩），在澳大利亚和加拿大招募了轻度（49.6％）至中度（50.4％）ID。潜在概况分析揭示了五个概况：（1）平均体质低估（样本的5.5％）；（2）适度高估低体质（17.7％），(3)适度低估平均体质(31.3%);(4)高度高估平均体质(28.3%);(5)适度低估高体质,准确估计平均弹性(17.2%)。简介1、2和3的简介4和5的亲戚包括年轻的参与者，更多具有中等水平ID的参与者，以及体重指数较高的参与者。此外,简介1和3还包括追求外部驱动动机的青年比例较高，而在校外从事体育活动的频率较低。总之,我们的发现表明，有ID的年轻人倾向于依赖向上或向下横向的社会比较，这可能导致他们的身体素质低下或高估。
