Rates of alcohol consumption are substantially higher among persons with pain, and recent research has focused on elucidating bidirectional pain-alcohol effects. Expectancies for alcohol analgesia could influence the degree to which alcohol confers acute pain-relieving effects, and may amplify the propensity to respond to pain with drinking behavior. However, no validated measures of expectancies for alcohol analgesia are available. Therefore, we developed a five-item measure of Expectancies for Alcohol Analgesia (EAA), which assesses the perceived likelihood that alcohol will reduce pain. The goal of this project was to examine psychometric properties of the EAA among a sample of 273 current alcohol users with chronic pain (M_age = 32.9; 34% female) who completed an online survey of pain and substance use. Confirmatory factor analysis (CFA) results indicated that the hypothesized single-factor structure of the EAA provided good model fit (Bollen-Stine bootstrap p = .13). The EAA also showed excellent internal consistency (α = 0.97), and scores were positively associated with quantity/frequency of alcohol use, alcohol outcome expectancies, coping-related drinking motives, and pain severity (ps < 0.01). These findings provide initial support regarding the single-factor structure, reliability, and validity of the EAA. Examination of predictive utility and further validation are important next steps.

疼痛患者的饮酒率要高得多，最近的研究集中在阐明疼痛-酒精的双向作用。对酒精镇痛的期望可能会影响酒精对急性疼痛缓解作用的程度，并可能放大对饮酒行为疼痛的反应倾向。然而，目前还没有经过验证的酒精镇痛预期指标。因此，我们制定了酒精镇痛预期 (EAA) 的五项测量方法，用于评估酒精减轻疼痛的感知可能性。该项目的目的是在 273 名当前患有慢性疼痛的酒精使用者样本中检查 EAA 的心理测量特性（M_年龄 = 32.9; 34% 的女性）完成了关于疼痛和药物使用的在线调查。验证性因素分析 (CFA) 结果表明，假设的 EAA 单因素结构提供了良好的模型拟合 (Bollen-Stine bootstrap p  = .13)。EAA 也显示出极好的内部一致性（α = 0.97），分数与饮酒量/频率、预期饮酒结果、应对相关饮酒动机和疼痛严重程度呈正相关（p s < 0.01）。这些发现为 EAA 的单因素结构、可靠性和有效性提供了初步支持。检查预测效用和进一步验证是重要的后续步骤。
