Given the pressure that educators and policy makers are under to achieve academic standards for students, understanding the relationship of academic success to various aspects of health is important. The international Health Behavior in School-Aged Children (HBSC) questionnaire, being used in 41 countries with different school and grading systems, has contained an item assessing perceived school performance (PSP) since 1986. Whereas the test-retest reliability of this item has been reported previously, we determined its convergent and discriminant validity.
This cross-sectional study used anonymous self-report data from Austrian (N = 266), Norwegian (N = 240), and Canadian (N = 9,717) samples. Students were between 10 and 17 years old. PSP responses were compared to the self-reported average school grades in 6 subjects (Austria) or 8 subjects (Norway), respectively, or to a general, 5-category-based appraisal of most recent school grades (Canada).
Correlations between PSP and self-reported average school grade scores were between 0.51 and 0.65, representing large effect sizes. Differences between the median school grades in the 4 categories of the PSP item were statistically significant in all 3 samples. The PSP item showed predominantly small associations with some randomly selected HBSC items or scales designed to measure different concepts.
The PSP item seems to be a valid and useful question that can distinguish groups of respondents that get good grades at school from those that do not. The meaning of PSP may be context-specific and may have different connotations across student populations from different countries with different school systems.
鉴于教育工作者和政策制定者面临着提高学生学业水平的压力，了解学业成功与健康各个方面的关系非常重要。国际学生健康行为调查（HBSC）问卷自 1986 年以来一直在 41 个国家使用，这些国家的学校和评分系统各不相同，其中包含一项评估感知学业表现（PSP）的项目。虽然此前已经报告了该项目的重测信度，但我们确定了其聚合和区分效度。
本横断面研究使用了来自奥地利（N=266）、挪威（N=240）和加拿大（N=9717）样本的匿名自我报告数据。学生年龄在 10 至 17 岁之间。PSP 反应与自我报告的 6 门学科的平均学校成绩（奥地利）或 8 门学科的平均成绩（挪威）进行比较，或者与最近学校成绩的一般 5 级评价（加拿大）进行比较。
PSP 与自我报告的平均学校成绩之间的相关性在 0.51 到 0.65 之间，代表着较大的效应量。在所有 3 个样本中，PSP 项目的 4 个类别中，中位数学校成绩之间的差异均具有统计学意义。PSP 项目与一些随机选择的 HBSC 项目或旨在衡量不同概念的量表主要呈小关联。
PSP 项目似乎是一个有效的、有用的问题，可以区分在学校获得好成绩的和没有获得好成绩的受访者群体。PSP 的含义可能是特定于情境的，并且在来自不同国家、具有不同学校系统的学生群体中可能具有不同的内涵。
