Given the strict prohibition of alcohol use in certain religions, such as Islam, and the criminalization of its production, distribution, and consumption in a country like Iran, it becomes essential to utilize a standardized and culturally appropriate instrument to study various dimensions of alcohol consumption within this context. Accordingly, this study aimed to develop the Iranian Students' Alcohol-Related Knowledge, Attitude, and Practice Questionnaire (ISKAP Alcohol Q) and evaluate its psychometric properties.
This study was conducted in three phases. After a comprehensive literature review, the item pool was developed. Content validity was determined based on the content validity ratio (CVR) and content validity index (CVI). For face validity, 11 experts were asked to interpret the items. The clarity and readability of the instrument were checked by 15 students. Using stratified sampling proportional to the population size, 512 respondents from the universities of Kerman, southeast Iran, were recruited from May to September 2023 to participate in the validation process of this study. Construct validity was assessed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The reliability of the questionnaire was also checked by calculating Cronbach's alpha and composite reliability for each factor.
The final questionnaire, besides the demographic (7 items) and questions related to the first experience of alcohol consumption and cost (5 items), included 33 items, including three main constructs: knowledge, attitude, and practice. The constructs of knowledge and practice included one factor each, with seven and five items, respectively. The construct of attitude also included the three factors of positive attitude, social influences attitude, and individual acceptance attitude, which included 21 items (factor loading > 0.4). Cronbach's alpha was acceptable for five factors (ranging from 0.75 to 0.93). Composite reliability was ≥ 0.71 for all factors.
The ISKAP Alcohol Q is a valid and reliable tool for evaluating the knowledge, attitudes, and practices of Iranian university students regarding alcohol consumption. It is currently accessible by contacting the authors of the article and can be utilized to assess alcohol consumption and its associated factors in future studies.
鉴于某些宗教（如伊斯兰教）严格禁酒，以及在伊朗等国家将酒精的生产、销售和消费定为犯罪行为，因此有必要使用一种标准化且符合文化背景的工具来研究在此背景下酒精消费的各个方面。因此，本研究旨在开发伊朗学生酒精相关知识、态度和行为问卷（ISKAP酒精问卷）并评估其心理测量特性。
本研究分三个阶段进行。在全面的文献综述之后，建立了项目池。基于内容效度比（CVR）和内容效度指数（CVI）确定内容效度。为了进行表面效度评估，邀请了11位专家对项目进行解读。由15名学生检查该工具的清晰度和可读性。采用与人口规模成比例的分层抽样方法，于2023年5月至9月从伊朗东南部克尔曼市的大学招募了512名受访者，参与本研究的验证过程。使用探索性因素分析（EFA）和验证性因素分析（CFA）评估结构效度。还通过计算每个因素的克朗巴哈系数（Cronbach's alpha）和组合信度来检查问卷的信度。
最终问卷除了人口统计学项目（7项）以及与首次饮酒经历和成本相关的问题（5项）外，还包括33项，涵盖三个主要结构：知识、态度和行为。知识和行为结构各包含一个因素，分别有7项和5项。态度结构还包括积极态度、社会影响态度和个人接受态度这三个因素，共21项（因子载荷>0.4）。五个因素的克朗巴哈系数均可接受（范围为0.75至0.93）。所有因素的组合信度≥0.71。
ISKAP酒精问卷是评估伊朗大学生酒精消费知识、态度和行为的有效且可靠的工具。目前可通过联系本文作者获取，可用于未来研究中评估酒精消费及其相关因素。
