摘要
本研究旨在验证意大利版多尺度解离量表 (MDI-ITA) 并评估其在非临床样本中的心理测量特性。 MDI 是按照既定准则进行翻译和文化调整的。共有 439 名讲意大利语的成年人参与了这项研究，并填写了 MDI-ITA 和其他针对分离性抑郁、焦虑、压力和创伤后症状的评估工具。使用探索性和验证性因素分析来评估 MDI-ITA 的内部一致性、重测可靠性和结构有效性。与之前的验证研究一致，这些分析支持五因素结构：脱离、人格解体/现实解体、情绪压抑、记忆障碍和身份分离。每个分量表的 Cronbach's α 值均大于 0.71，表现出令人满意的内部一致性。重测信度也很高，相关性为 0.91。 MDI-ITA 与其他解离指标之间的显着正相关性支持了收敛效度。与抑郁、焦虑和创伤后症状的相关性较弱表明区分效度。 MDI-ITA 是评估意大利语人群解离现象的可靠且有效的工具，在临床和研究环境中都有潜在应用。它的多维结构提供了对解离的全面见解，促进针对出现这些症状的个人制定有针对性的干预措施。

This study aimed to validate the Italian version of the Multiscale Dissociation Inventory (MDI-ITA) and to assess its psychometric properties in a non-clinical sample. The MDI was translated and culturally adapted following established guidelines. A total of 439 Italian-speaking adults participated in the study and filled out the MDI-ITA and other assessment tools for dissociation depression, anxiety, stress, and post-traumatic symptoms. The internal consistency, test-retest reliability, and construct validity of the MDI-ITA were evaluated using exploratory and confirmatory factor analyses. Consistent with previous validation studies, the analyses supported a five-factor structure: Disengagement, Depersonalization/Derealization, Emotional Constriction, Memory Disturbance, and Identity Dissociation. Cronbach's alpha values for each subscale were all greater than 0.71, demonstrating satisfactory internal consistency. Test-retest reliability was also high, with a correlation of 0.91. Convergent validity was supported by significant positive correlations between MDI-ITA and other dissociation measures. Discriminant validity was indicated by weaker correlations with depression, anxiety, and post-traumatic symptoms. The MDI-ITA is a reliable and valid tool for assessing dissociative phenomena in Italian-speaking populations with potential applications in both clinical and research settings. Its multidimensional structure offers comprehensive insights into dissociation, facilitating the development of targeted interventions for individuals presenting with these symptoms.
