The aim of this study was to validate five scales, based on a theoretical framework for the adoption of behaviours, designed to assess the determinants in binge drinking in adolescents, namely: attitude, social influence (model, norm and pressure) and self-efficacy.
Observational, cross-sectional and multicentre study. Through convenience sampling, 397 adolescents between 15 to 18 years old enrolled in secondary schools in Seville and Huelva were included. After translation and review of the original instrument by a panel of experts, a questionnaire was obtained in Spanish that was administered to a pilot sample to assess comprehensibility and, subsequently, the participants completed the five scales to check the structural validity (factor analysis and reliability) and construct validity.
On the five scales, the first factor explained at least 28% of the variance and the total variance explained was always greater than 60%. After rotation, all items had weights >0.40 for the factor to which they belonged. Cronbach´s alpha ranged from 0.62 to 0.91. Spearman's coefficient was lower than 0.7 when correlating the sub-dimensions of the scales, except on the self-efficacy scale, assuming multidimensionality with certain limitations.
Five scales are presented with indications of reliability and validity, their items reflect the theoretical frame of reference and can evaluate the determinants of binge drinking. In the future, validation could be continued to determine its reproducibility, its criterion validity with a "gold standard" or objective measure. Key words. Adolescents. Health behaviour.

本研究旨在基于行为采纳的理论框架，验证五个量表，这些量表旨在评估青少年暴饮的决定因素，即：态度、社会影响（榜样、规范和压力）以及自我效能感。
观察性、横断面多中心研究。通过便利抽样，纳入了塞维利亚和韦尔瓦市中学的397名15至18岁的青少年。在由专家小组对原始工具进行翻译和审核后，获得了一份西班牙语问卷，该问卷被用于一个试点样本以评估其可理解性，随后参与者完成这五个量表以检验结构效度（因子分析和信度）以及构想效度。
在这五个量表上，第一个因子解释了至少28%的方差，且解释的总方差始终大于60%。旋转后，所有项目对于其所属因子的权重均>0.40。克朗巴赫α系数范围为0.62至0.91。量表各子维度之间的斯皮尔曼系数低于0.7，但自我效能感量表除外，该量表在存在一定局限性的情况下假设具有多维性。
呈现了五个具有信度和效度指标的量表，其项目反映了理论参照框架，并且能够评估暴饮的决定因素。未来，可以继续进行验证以确定其可重复性、与“金标准”或客观测量的效标效度。关键词：青少年。健康行为。暴饮。风险因素。验证研究。
