Report on the development and psychometric testing of a theoretically and evidence-grounded instrument, the Characteristics of Responsible Drinking Survey (CHORDS).
Instrument subjected to four phases of pretesting (cognitive validity, cognitive and motivational qualities, pilot test, and item evaluation) and a final posttest implementation.
Large public university in Texas.
Randomly selected convenience sample (n = 729) of currently enrolled students.
This 78-item questionnaire measures individuals' responsible drinking beliefs, motivations, intentions, and behaviors. Cronbach α, split-half reliability, principal components analysis and Spearman ρ were conducted to investigate reliability, stability, and validity.
Measures in the CHORDS exhibited high internal consistency reliability and strong correlations of split-half reliability. Factor analyses indicated five distinct scales were present, as proposed in the theoretical model. Subscale composite scores also exhibited a correlation to alcohol consumption behaviors, indicating concurrent validity.
The CHORDS represents the first instrument specifically designed to assess responsible drinking beliefs and behaviors. It was found to elicit valid and reliable data among a college student sample. This instrument holds much promise for practitioners who desire to empirically investigate dimensions of responsible drinking.
报告一种理论和证据基础的工具，即负责任饮酒特征调查（CHORDS）的开发和心理计量学测试。
该仪器经过四个阶段的预测试（认知有效性、认知和动机质量、试点测试和项目评估）和最终的后测试实施。
德克萨斯州的一所大型公立大学。
随机抽取的便利样本（n=729），包括目前在校的学生。
该问卷有 78 个项目，用于测量个体的负责任饮酒信念、动机、意图和行为。进行了克朗巴赫α系数、分半信度、主成分分析和斯皮尔曼 ρ检验，以考察可靠性、稳定性和有效性。
CHORDS 中的测量方法表现出较高的内部一致性可靠性和分半可靠性的强相关性。因子分析表明，如理论模型所提出的，存在五个不同的量表。子量表综合得分也与酒精消费行为相关，表明具有同时效度。
CHORDS 是第一个专门设计用于评估负责任饮酒信念和行为的工具。在大学生样本中发现它能得出有效和可靠的数据。该工具为希望实证研究负责任饮酒各个维度的从业者提供了很大的希望。
