Given the popularity and ease of single-item craving assessments, we developed a multi-item measure and compared it to common single-item assessments in an ecological momentary assessment (EMA) context. Two weeks of EMA data were collected from 48 emerging adults (56.25% female, 85.42% White) who frequently used cannabis. Eight craving items were administered, and multilevel factor analyses were used to identify the best fitting model. The resulting scale's factors represented purposefulness/general desire and emotionality/negative affect craving. Convergent validity was examined using measures of craving, cannabis use disorder symptoms, frequency of use, cannabis cue reactivity, cannabis use, negative affect, and impulsivity. The scale factors were associated with cue-reactivity craving, negative affect, impulsivity, and subfactors of existing craving measures. For researchers interested in using a single item to capture craving, one item performed particularly well. However, the new scale may provide a more nuanced assessment of mechanisms underlying craving.
鉴于单一项目渴望评估的普及和简易性，我们开发了一种多项目衡量标准，并在生态瞬间评估（EMA）背景下将其与常见的单一项目评估进行了比较。从经常使用大麻的 48 名新兴成年人（56.25%女性，85.42%白人）中收集了两周的 EMA 数据。共管理了 8 项渴望项目，并使用多层次因素分析来确定最合适的拟合模型。该量表的因素代表了目的性/一般欲望和情感性/消极情绪渴望。使用渴望、大麻使用障碍症状、使用频率、大麻线索反应性、大麻使用、消极情绪和冲动性的衡量标准来检查了聚合效度。该量表因素与线索反应性渴望、消极情绪、冲动性以及现有渴望衡量标准的子因素有关。对于有兴趣使用单一项目来捕捉渴望的研究人员来说，一个项目表现特别好。然而，新量表可能会更细致地评估渴望背后的机制。
