BACKGROUND
Suggestibility is a personality trait that reflects a general tendency to accept messages. The Multidimensional Iowa Suggestibility Scale (MISS) is a self-report scale developed to measure the degree of individuals' perceptions of their suggestibility. This study aimed to adapt the MISS in an Italian sample.
METHODS
We conducted two studies. In the first study, 345 subjects (270 females (78%), mean age = 36.21 years ± 14.06 SD) completed the translated Italian version of the MISS, composed of five subscales (consumer suggestibility; persuadability; sensation contagion; physiological reactivity; peer conformity). We investigated the structural validity of the scale through confirmatory factor analysis (CFA) testing four measurement models (unidimensional, four-factor, hierarchical four factors, and bifactor) and explored reliability in terms of internal consistency through the McDonald's omega. In the second study, we cross-validated the MISS on a new independent sample. We enrolled 277 participants (196 females (71%), mean age 30.56, SD = 12.58) who underwent the new version of the scale. We performed factor analyses to test structural validity and compared four measurement models. Then, we investigated reliability and conducted a latent variable analysis to explore divergent validity.
RESULTS
The CFA in the first study revealed a bifactor solution of the MISS. This structure was interpretable and provided an adequate fit for the data. The final version of the scale was reduced to forty-six items with globally good indices of adaptation. The scale also demonstrated acceptable reliability in terms of internal consistency through the McDonald's Hierarchical Omega. In the second study, we found that the bifactor structure was confirmed. Factor loadings inspection revealed that there was no justification to report only the separate scores for the subscales. We also found that the scale showed good internal consistency, but mixed evidence for divergent validity.
CONCLUSIONS
In the end, the Italian version of the MISS demonstrated good psychometric properties which will be discussed in detail below.
背景
易受暗示性是一种反映接受信息总体倾向的人格特质。多维爱荷华易受暗示性量表（MISS）是一种为测量个体对自身易受暗示性的感知程度而编制的自陈量表。本研究旨在使MISS适用于意大利样本。
方法
我们进行了两项研究。在第一项研究中，345名受试者（270名女性（78%），平均年龄 = 36.21岁 ± 14.06标准差）完成了意大利语翻译版的MISS，该量表由五个分量表组成（消费者易受暗示性；可说服性；感觉感染；生理反应；同伴从众性）。我们通过验证性因素分析（CFA）测试四种测量模型（单维、四因素、层次四因素和双因素）来研究该量表的结构效度，并通过麦克唐纳ω系数从内部一致性方面探讨信度。在第二项研究中，我们在一个新的独立样本上对MISS进行交叉验证。我们招募了277名参与者（196名女性（71%），平均年龄30.56，标准差 = 12.58），他们接受了新版本的量表。我们进行因素分析以测试结构效度，并比较四种测量模型。然后，我们研究信度并进行潜在变量分析以探讨区分效度。
结果
第一项研究中的CFA揭示了MISS的双因素结构。这种结构是可解释的，并且对数据提供了充分的拟合。该量表的最终版本缩减为46个项目，具有总体良好的适配指标。该量表通过麦克唐纳层次ω系数在内部一致性方面也表现出可接受的信度。在第二项研究中，我们发现双因素结构得到了证实。因素载荷检验表明，没有理由只报告分量表的单独得分。我们还发现该量表显示出良好的内部一致性，但区分效度的证据不一。
结论
最终，意大利语版的MISS表现出良好的心理测量特性，将在下文详细讨论。
