The factor structure, measurement invariance, validity, reliability, and stability of scores on the Brief Situational Confidence Questionnaire (BSCQ) were evaluated for use with incarcerated youth. The BSCQ is an 8-item measure that assesses self-efficacy to resist alcohol use in tempting situations. The brevity of the measure may make it a useful tool for clinicians and researchers in a forensic setting. Analyses were conducted with 2 separate samples ( = 205 and = 189) of incarcerated youth ( age = 16.90 and 17.12 years, respectively; 88% and 86% male). Based on prior theory and confirmatory factor analyses (CFAs), results indicated that a correlated 2-factor model best fit the data. Multisample CFAs suggested that BSCQ scores demonstrated configural and metric invariance across our 2 samples. Further, the BSCQ scores demonstrated sufficient test-retest stability in Samples 1 and 2 (Pearson's = .66, .55) and internal consistency (Cronbach's α = .84 and .86, respectively). Negative binomial regressions showed that the overall BSCQ scores were significantly associated with concurrent alcohol use (number of drinking days, number of heavy drinking days, average drinks per week) and significantly predicted future alcohol use. Scores on the BSCQ demonstrated sufficient stability, internal consistency, and validity, and the 2-factor structure was largely invariant across 2 separate samples of incarcerated youth. Given its brevity, the BSCQ may provide valid and reliable scores to use with this population when time and resources are scarce. (PsycINFO Database Record (c) 2020 APA, all rights reserved).
该研究旨在评估Brief Situational Confidence Questionnaire（BSCQ）在青少年罪犯中的结构、测量不变性、有效性、信度和稳定性。BSCQ 是一种 8 项测量工具，用于评估在诱人情境下抵制饮酒的自我效能。该测量工具的简短性可能使其成为法医环境中临床医生和研究人员的有用工具。对 2 个独立样本（分别为 205 名和 189 名青少年罪犯）（年龄分别为 16.90 岁和 17.12 岁，分别为 88%和 86%为男性）进行了分析。基于先前的理论和验证性因素分析（CFAs），结果表明相关的 2 因素模型最适合数据。多样本 CFA 表明，BSCQ 分数在我们的 2 个样本中表现出结构和度量不变性。此外，BSCQ 分数在样本 1 和 2 中具有足够的重测信度（Pearson's =.66，.55）和内部一致性（Cronbach's α 分别为.84 和.86）。负二项回归表明，BSCQ 的总分与同期饮酒（饮酒天数、重度饮酒天数、每周平均饮酒量）显著相关，且显著预测未来饮酒。BSCQ 的分数具有足够的稳定性、内部一致性和有效性，2 因素结构在 2 个独立的青少年罪犯样本中基本不变。鉴于其简短性，BSCQ 可能会在时间和资源匮乏时为该人群提供有效和可靠的分数。（PsycINFO 数据库记录（c）2020 APA，保留所有权利）。
