Insomnia Severity Index (ISI) is one of the most widely used screening instruments for chronic insomnia, yet limitations in prior studies leave aspects of its psychometric properties incomplete. This study aimed to validate the ISI and investigate its screening utility in a clinical and nonclinical Romanian sample (N = 326; Mage = 25.84). Results indicate good internal consistency (αT1 = .84, αT2 = .86) and good test-rest reliability (r = .82). ISI significantly correlates with depression (r = .69), anxiety (r = .52), self-esteem (r = -.42), and quality of sleep (r = .75), supporting its concurrent and convergent validity. Regression analyses confirm its predictive validity, based on neurologists' (β = .39) and clinicians' (β = .43) diagnostic ratings of chronic insomnia. A cutoff score of 13 is optimal for a good balance between sensitivity (.79) and specificity (.68). Confirmatory factor analysis supports a two-factor model. Moreover, measurement invariance analyses show that ISI functions equivalently across the clinical and nonclinical groups. Overall, ISI scores provide reliable and valid information for screening chronic insomnia in patients with or without other psychiatric and/or medical conditions.

Alcohol demand, reflecting the relative reinforcing value of alcohol, is robustly associated with alcohol use and problems. Alcohol demand is typically assessed using alcohol purchase tasks (APTs) in which participants estimate alcohol consumption at escalating prices, with the resulting demand curves yielding multiple indices of value. Although generally efficient, full-length APTs pose some burden and existing short forms cannot produce individual demand curves or derived indices. Thus, we developed a brief adjusting APT using an algorithm to identify 5-6 items from a full-length APT based on an individual's level of alcohol demand. Two independent samples of heavy-drinking young adults (Sample 1: N = 725, Mage = 21.43 years; Sample 2: N = 588, Mage = 22.64 years) completed an assessment that included a full-length APT and measures of alcohol use and problems. Using a binary-search-style algorithm, brief APT responses were extracted from the full-length APT. In each sample, individual demand curves from the brief APT fit the data well. Observed (intensity, Omax, breakpoint) and derived (elasticity) demand indices robustly corresponded with the full-length APT, including similar mean estimates and high correlations (r ≥ 0.79) between corresponding indices from the brief and full-length APTs. Demand indices from the brief APT were associated with alcohol use and problems, and associations of corresponding indices from the brief and full-length APTs with alcohol use outcomes were of equivalent magnitude. These findings provide initial support for a brief adjusting APT as a measure of alcohol demand. Future research should further evaluate this measure, including stand-alone administration and detection of within-person changes in alcohol demand.

酒精需求反映了酒精的相对强化价值，与酒精使用和酒精问题密切相关。酒精需求通常是通过酒精购买任务（APTs）来评估的，在该任务中，参与者估计在不断上涨的价格下的酒精消费量，由此产生的需求曲线产生多个价值指数。全长apt虽然总体效率较高，但存在一定的负担，且现有的短格式无法生成单个需求曲线或衍生指标。因此，我们开发了一个简短的调整APT，使用一种算法，根据个人的酒精需求水平，从全长APT中识别5-6个项目。两个独立的重度饮酒年轻人样本（样本1:N = 725，年龄21.43岁；样本2:N = 588，年龄22.64岁）完成了一项评估，包括完整的APT和酒精使用和问题的测量。使用二叉搜索算法，从全长APT中提取简短的APT响应。在每个样本中，简短APT的个人需求曲线与数据拟合良好。观察到的（强度、Omax、断点）和推导出的（弹性）需求指数与全长APT具有良好的对应关系，包括相似的均值估计和短时间APT与全长APT对应指数之间的高相关性（r≥0.79）。简短APT的需求指数与酒精使用和问题相关，简短APT和全长APT的相应指数与酒精使用结果的关联程度相等。这些发现为将APT作为酒精需求的衡量标准进行简要调整提供了初步支持。未来的研究应进一步评估这一措施，包括独立管理和检测酒精需求的个人变化。（PsycInfo Database Record (c) 2025 APA，版权所有）。
