Abstract

Introduction: There has been long-standing interest in the physiological and psychological effects of mild hypoxia on aircrew, but to date there is no psychometrically valid self-report measure of subjective symptoms.

Methods: To address this gap, we developed a self-report scale along three dimensions of impairment: cognitive, sensory and affective. We administered this scale to active and retired aircrew (N = 354) with on average 25.04 yr (SD = 11.27) of military service and subjected their responses to exploratory factor analysis using Maximum Likelihood Estimation, followed by reliability analysis to determine cohesiveness of associated items.

Results: We provide initial psychometric validation for our 12-item scale's three-dimensional structure. The internal consistency reliability of the cognitive, sensory, and affective factors was 0.90, 0.75, and 0.85, respectively.

Discussion: Going forward, the consistent use of this instrument will likely reduce the methodological variability in measuring the symptoms of mild hypoxia in the literature.

轻度缺氧症状自我报告测量的初步心理测量学验证。

长期以来，人们一直对机组人员轻度缺氧的生理和心理影响感兴趣，但迄今为止，还没有心理测量学上有效的主观症状自我报告测量方法。方法：为了解决这一差距，我们开发了一个自我报告量表，沿着三个维度的损害：认知，感觉和情感。我们将此量表应用于现役和退役机组人员（N = 354），平均服役25.04年（SD = 11.27），并使用最大似然估计对他们的回答进行探索性因素分析，然后进行信度分析以确定相关项目的凝聚力。结果：我们对12项量表的三维结构进行了初步的心理计量学验证。认知、感觉和情感因素的内部一致性信度分别为0.90、0.75和0.85。讨论：展望未来，该仪器的持续使用可能会减少文献中测量轻度缺氧症状的方法可变性。Vartanian O, Bouak F, Lam Q, Miles R.轻度缺氧症状自我报告测量的初步心理测量学验证。航空航天Med Hum Perform. 2025；96(9): 851 - 856。
