临床医生越来越需要短，有效的方法来评估痛苦，无论是在应用研究和临床设置。大多数可用的问卷不适合繁忙的临床环境。视觉模拟量表（visual analogue scale， VAS）被广泛地用于评估感知压力。目的为VAS的两个心理测量特性提供证据：其判别敏感性（突出组间差异的能力）和概念间效度（VAS压力评估与不同但相似的概念评估之间的关系）。方法随机选取在职业健康中心就诊的员工，分别完成VAS和压力感知量表（PSS）或医院焦虑抑郁量表（HADS）。采用方差分析研究各组（年龄、性别、婚姻状况、父母状况、职业状况）对压力评分（PSS和VAS）的影响。结果共有763名员工参与，其中501人完成了PSS， 262人完成了HADS。性别、年龄和职业状况对VAS影响的p值低于PSS。VAS与焦虑量表、抑郁量表及HADS总分的相关系数分别为0.66、0.45、0.65。其他用于评估心理困扰方面的工具也有类似的相关性。结论我们的研究结果提供了证据，证明VAS在强调两组之间的压力水平差异时至少与问卷一样具有区别性，并且观察到的相关构念的相关性支持其构念效度。
Background Clinicians increasingly require short, efficient methods for assessing distress, both in applied research and clinical settings. Most of the available questionnaires are unsuitable for busy clinical settings. The visual analogue scale (VAS) is widely but empirically used to assess perceived stress.Aims To provide evidence on two of the psychometric properties of the VAS: its discriminative sensitivity (capacity to highlight a difference between groups) and its interconcept validity (the relationship between VAS stress assessment and the assessment of different, but similar concepts).Methods Employees attending occupational health centres were randomly selected and completed the VAS and also either the Perceived Stress Scale (PSS) or the Hospital Anxiety and Depression Scale (HADS). Analyses of variance were performed to study group effects (age, sex, marital status, parental status, occupational status) on stress scores (PSS and VAS).Results In total, 763 employees participated of whom 501 completed the PSS and 262 the HADS. P-values obtained for the effects of sex, age and occupational status were lower with the VAS than with the PSS. Correlations between the VAS and the anxiety subscale, depression subscale and total score of the HADS were 0.66, 0.45 and 0.65, respectively. Other tools used to assess aspects of psychological distress are known to have similar correlations.Conclusions Our findings provide evidence that the VAS is at least as discriminating as a questionnaire when it comes to highlighting differences in stress levels between two groups, and the observed correlations with related constructs support its construct validity.
