治疗焦虑的速效药物对患者和社会都很重要。然而，测量早期发病需要一种敏感和临床反应灵敏的工具。本研究评估了患者报告的全局焦虑-视觉模拟量表（GA-VAS）的心理测量特性。对劳拉西泮和帕罗西汀在广泛性焦虑障碍患者中的双盲、随机、安慰剂对照研究数据进行分析，以评估GA-VAS的可靠性、有效性、反应性和实用性。GA-VAS在治疗的第一周分别在诊所和家中完成。进行了针对性的心理测量分析——重测信度、效度相关性、反应性统计和最小重要差异。GA-VAS与其他焦虑测量具有良好的相关性，在第4周，汉密尔顿焦虑评定量表的r = 0.60 (p < 0.0001)，医院焦虑和抑郁量表-焦虑子量表的r = 0.74 （p < 0.0001）。在收敛效度和发散效度方面，GA-VAS与SF-36情感角色、社会功能和心理健康量表的相关性分别为-0.54 （p < 0.0001）、-0.48 （p < 0.0001）和-0.68 (p < 0.0001)，但与SF-36身体功能量表的相关性要低得多。初步的最小重要差异估计在10到15毫米之间。GA-VAS能够在给药后24小时内有效地捕捉到焦虑的减少。
Fast-acting medications for the management of anxiety are important to patients and society. Measuring early onset, however, requires a sensitive and clinically responsive tool. This study evaluates the psychometric properties of a patient-reported Global Anxiety - Visual Analog Scale (GA-VAS). Data from a double-blind, randomized, placebo-controlled study of lorazepam and paroxetine in patients with Generalized Anxiety Disorder were analyzed to assess the reliability, validity, responsiveness, and utility of the GA-VAS. The GA-VAS was completed at clinic visits and at home during the first week of treatment. Targeted psychometric analyses—test-retest reliabilities, validity correlations, responsiveness statistics, and minimum important differences—were conducted. The GA-VAS correlates well with other anxiety measures, at Week 4, r = 0.60 (p < 0.0001) with the Hamilton Rating Scale for Anxiety and r = 0.74 (p < 0.0001) with the Hospital Anxiety and Depression Scale - Anxiety subscale. In terms of convergent and divergent validity, the GA-VAS correlated -0.54 (p < 0.0001), -0.48 (p < 0.0001), and -0.68 (p < 0.0001) with the SF-36 Emotional Role, Social Function, and Mental Health subscales, respectively, but correlated much lower with the SF-36 physical functioning subscales. Preliminary minimum important difference estimates cluster between 10 and 15 mm. The GA-VAS is capable of validly and effectively capturing a reduction in anxiety as quickly as 24 hours post-dose.
