Substance use is highly prevalent among Chilean adolescents, and the damage it causes at the neurobiological, psychological, and social levels is known. However, there are no validated screening instruments that also assess risk and protective factors for this population in Chile, which is essential for evaluating future prevention interventions.
To determine the psychometric properties of the European Drug Addiction Prevention Trial Questionnaire (EU-Dap) questionnaire.
A cross-sectional study was carried out in 13 schools in the city of Santiago de Chile. The sample included 2261 adolescents ranging from 10 to 14 years old. Linguistic and cultural adaptation was assessed using focus groups with adolescents, the construct validity was evaluated using confirmatory factor analysis, and measures of its reliability were also determined. Furthermore, the associations regarding risk and protective factors with substance use were explored.
Substance use questions were well understood and seemed to adequately capture the consumption of different drugs. Regarding the subscales of risk and protective factors, the analyses showed that most subscales had good psychometric properties, and few needed some degree of improvement (e.g., some items were removed). After the changes, most final subscales had good or adequate goodness of fit adjustments and good or acceptable internal consistency. Finally, the main associated factors with the substance use outcomes were: future substance use and school bonding for tobacco use; negative beliefs about alcohol, future substance use, school bonding and refusal skills for alcohol use; and negative beliefs about marihuana, positive attitudes towards drugs, risk perception, and substance abuse index for marihuana use. Normative beliefs increased the risk for all substances use.
The current findings suggest that the EU-Dap is a valid and reliable instrument, and it may help to evaluate the effectiveness of drug use prevention interventions.
物质滥用在智利青少年中非常普遍，其在神经生物学、心理学和社会层面造成的危害是众所周知的。然而，智利目前没有经过验证的筛查工具来评估该人群的风险和保护因素，而这对于评估未来的预防干预措施至关重要。
确定欧洲药物滥用预防试验问卷（EU-Dap）问卷的心理测量特性。
在智利圣地亚哥市的 13 所学校进行了一项横断面研究。样本包括 2261 名年龄在 10 至 14 岁之间的青少年。使用青少年焦点小组评估语言和文化适应性，使用验证性因素分析评估结构有效性，并确定其可靠性度量。此外，还探讨了与风险和保护因素有关的物质使用关联。
物质使用问题得到了很好的理解，似乎能够充分捕捉到不同药物的使用情况。关于风险和保护因素的子量表，分析表明，大多数子量表具有良好的心理测量特性，只有少数需要一定程度的改进（例如，删除一些项目）。经过更改后，大多数最终子量表的拟合优度调整较好或适当，内部一致性较好或可接受。最后，与物质使用结果主要相关的因素是：未来的物质使用和对学校的归属感与烟草使用有关；对酒精的负面看法、未来的物质使用、对学校的归属感和拒绝技能与酒精使用有关；对大麻的负面看法、对药物的积极态度、风险感知和大麻使用的物质滥用指数与大麻使用有关。规范信念增加了所有物质使用的风险。
目前的研究结果表明，EU-Dap 是一种有效且可靠的工具，它可以帮助评估药物使用预防干预措施的效果。
