we present in this paper a complete Italian validation version. We show some psychometric properties of the Italian version of the DEMQOL-PROXY: Structural validity (by use Exploratory Factor Analysis), convergent validity and divergent validity in Italian language Method.We enrolled a sample of 182 caregivers of people with mild to moderate Dementia. In particular, we collected 90 questionnaires of professional caregivers and 92 questionnaires of family caregivers. We used Exploratory Factor Analysis (Varimax rotation), to identify the saturation of items on the relevant factors.The internal consistency of the instrument was evaluated by using the Cronbach Alpha coefficient. Finally, referring to the Validity of convergent and Divergent validity, we used Spearman's correlation coefficient by comparing the various instruments of the study.
Our result shows that the variance explained by 4 factors corresponds to almost 51% of the total variance. Factors extracted in our Italian version are: Cognition;Negative and Positive emotion; Daily activity and Membership.
The Italian version of the DEMQOL-PROXY point out very good psychometric properties: factors extracted are similar to the original version and convergent and divergent validity show good proprieties. We consider this paper as a complete Italian Validation.
我们在本文中呈现了一个完整的意大利语验证版本。我们展示了 DEMQOL-PROXY 意大利语版本的一些心理测量学特性：结构有效性（通过使用探索性因素分析）、在意大利语中的收敛有效性和发散有效性。我们招募了 182 名轻度至中度痴呆患者的照顾者作为样本。具体来说，我们收集了 90 份专业照顾者的问卷和 92 份家庭照顾者的问卷。我们使用探索性因素分析（Varimax 旋转）来确定相关因素的项目饱和度。使用 Cronbach Alpha 系数评估工具的内部一致性。最后，关于收敛和发散有效性的有效性，我们通过比较研究中的各种工具使用 Spearman 相关系数。
我们的结果表明，由 4 个因素解释的方差对应于总方差的近 51%。在我们的意大利语版本中提取的因素是：认知；负性和正性情绪；日常活动和成员身份。
DEMQOL-PROXY 的意大利语版本表现出非常好的心理测量学特性：提取的因素与原始版本相似，收敛有效性和发散有效性显示出良好的特性。我们认为本文是一个完整的意大利语验证。
