Reliable and valid assessment tools are crucial for measuring alcohol use expectancies (AUE) among youth living with HIV (YLHIV). In this paper, we assess the psychometric properties of the original 17-item East Africa Alcohol Expectancy Scale (AFEXS) among Ugandan YLHIV-a scale developed and validated by Woolf-King et al. for use among Uganda adults living with HIV. Specifically, we applied the measure to a sample of 100 Ugandan YLHIV enrolled in a substance use intervention. To analyze the psychometric properties, we conducted exploratory factor analysis (EFA), confirmatory factor analysis (CFA), and convergent validity analyses. The resulting 15-item youth AFEXS scale differed from the 11-item adult version. The 15-item Youth AFEXS demonstrated high internal consistency (α = 0.85), aligning with theoretical expectations of a three-factor structure related to sexual expectancies (7 items; α = 0.89), negative expectancies (4 items; α = 0.72), and release of inhibition expectancies (4 items; α = 0.77). The global scale and sub-scales demonstrated satisfactory convergent validity through positive correlations measures of frequency of alcohol consumption in the past 12 months: global AFEXS (r = 0.617; p = 0.000), sexual expectancies (r = 0.583; p = 0.000), negative expectancies (r = 0.618; p = 0.000), and release expectancies (r = 0.596; p = 0.000). The study confirms the youth AFEXS as a reliable and valid tool for assessing AUE among Ugandan YLHIV.
可靠且有效的评估工具对于测量感染艾滋病毒的青年（YLHIV）的饮酒预期（AUE）至关重要。在本文中，我们评估了最初的17项东非酒精预期量表（AFEXS）在乌干达YLHIV中的心理测量特性——该量表由伍尔夫 - 金等人开发并验证，用于乌干达感染艾滋病毒的成年人。具体而言，我们将该测量方法应用于100名参与物质使用干预的乌干达YLHIV样本。为了分析心理测量特性，我们进行了探索性因素分析（EFA）、验证性因素分析（CFA）和收敛效度分析。由此产生的15项青年AFEXS量表与11项成人版本不同。15项青年AFEXS表现出较高的内部一致性（α = 0.85），符合与性预期（7项；α = 0.89）、消极预期（4项；α = 0.72）和抑制释放预期（4项；α = 0.77）相关的三因素结构的理论预期。通过过去12个月饮酒频率的正相关测量，总体量表和子量表显示出令人满意的收敛效度：总体AFEXS（r = 0.617；p = 0.000）、性预期（r = 0.583；p = 0.000）、消极预期（r = 0.618；p = 0.000）和释放预期（r = 0.596；p = 0.000）。该研究证实青年AFEXS是评估乌干达YLHIV中AUE的可靠且有效的工具。
