Αlcohol abuse/dependence seriously affects quality of life (QoL). The AlQoL-9 scale, derived from the generic instrument SF-36, is the only instrument in the international literature which is specific as a measure of QoL for alcohol-dependent patients. It can provide health carers with valuable information regarding the needs of alcoholic individuals and the effects of therapeutic interventions. The aim of this study was to assess the psychometric properties of the Greek version of AlQoL-9 taking as a basis the research on the original French and English versions. A sample of 170 participants (118 males, 52 females) aged 24-74 years (mean age=48.2 years, SD=9.6) recruited from inpatient and outpatient detoxification units in different regions of Greece completed the AlQoL-9 questionnaire and the World Health Organization Quality of Life Assessment - short version (WHOQOL-BREF). The internal structure of the AlQoL-9 questionnaire was examined using confirmatory factor analysis (CFA). The associations of AlQoL-9 with sociodemographic and clinical variables were examined. The correlation coefficients between AlQoL-9 and scores on the domains of the WHOQOL-BREF questionnaire were computed as an indication of convergent validity. The average inter-item correlation between the AlQoL-9 items was 0.403. CFA supported a single factor underlying the AlQoL-9 items. Cronbach's alpha for the Greek version of the scale showed high internal consistency, 0.837, and could not be improved by omitting any item. The AlQoL-9 score showed significant associations with gender (mean 29.2, SD=6.2 for males; mean 26.1, SD=7.2 for females: p=0.004) and with comorbidity (mean 25.7, SD=7.8 with comorbidity, mean 29.5, SD=5.8 without: p=0.001). The AlQoL-9 score was significantly correlated (p<0.001) with all scores of the WHOQOL-BREF, most strongly with the WHOQOL domains of physical health (Pearson's r=0.720) and psychological health (r=0.693) and less so with social relationships (0.481), environment (0.411), and the single-item measures of overall health (0.554) and overall quality of life (0.522). The present study demonstrated that the Greek version of the AlQoL-9 constitutes a valid and reliable single-factor research instrument for evaluating quality of life among alcohol-dependent individuals. It is recommended to be used in combination with a generic QoL instrument e.g. the WHOQOL-BREF. It is suitable for clinical everyday practice to monitor possible patient QoL changes, as well as in large scale studies investigating QoL in the relevant population.
酒精滥用/依赖严重影响生活质量（QoL）。AlQoL - 9量表源自通用工具SF - 36，是国际文献中唯一专门用于衡量酒精依赖患者生活质量的工具。它可以为医护人员提供有关酗酒个体需求和治疗干预效果的有价值信息。本研究的目的是以对原始法语和英语版本的研究为基础，评估希腊语版AlQoL - 9的心理测量特性。从希腊不同地区的住院和门诊戒毒单位招募了170名年龄在24 - 74岁（平均年龄 = 48.2岁，标准差 = 9.6）的参与者（118名男性，52名女性），他们完成了AlQoL - 9问卷和世界卫生组织生活质量评估简表（WHOQOL - BREF）。使用验证性因子分析（CFA）检查AlQoL - 9问卷的内部结构。研究了AlQoL - 9与社会人口统计学和临床变量之间的关联。计算了AlQoL - 9与WHOQOL - BREF问卷各领域得分之间的相关系数，以作为收敛效度的指标。AlQoL - 9各项目之间的平均项间相关性为0.403。CFA支持AlQoL - 9项目背后的单一因子。该量表希腊语版的Cronbach's alpha显示出较高的内部一致性，为0.837，且删除任何项目都无法提高其一致性。AlQoL - 9得分与性别（男性平均29.2，标准差 = 6.2；女性平均26.1，标准差 = 7.2：p = 0.004）和合并症（有合并症者平均25.7，标准差 = 7.8，无合并症者平均29.5，标准差 = 5.8：p = 0.001）显著相关。AlQoL - 9得分与WHOQOL - BREF的所有得分均显著相关（p < 0.001），与身体健康（Pearson相关系数r = 0.720）和心理健康（r = 0.693）领域的相关性最强，与社会关系（0.481）、环境（0.411）以及整体健康（0.554）和整体生活质量（0.522）的单项测量相关性较弱。本研究表明，希腊语版的AlQoL - 9是一种有效且可靠的单因子研究工具，用于评估酒精依赖个体的生活质量。建议将其与通用生活质量工具（如WHOQOL - BREF）结合使用。它适用于临床日常实践，以监测患者生活质量可能的变化，也适用于在相关人群中调查生活质量的大规模研究。
