Abstract

Objectives: The Shared Decision Making Questionnaire-Physician Version (SDM-Q-Doc) is the main tool assessing SDM relationship between patient and physician using the clinician viewpoint. It is reliable in all medical fields, and the validation of its Italian version was still missing. Our aim was to validate the Italian version of the SDM-Q-Doc in a clinical sample of patients suffering from severe mental illness.

Methods: We approached 369 patients affected by major psychiatric disorders (including schizophrenia spectrum disorders, affective disorders and eating disorders) in a real-world outpatient clinical setting. We run the Confirmatory Factor Analysis (CFA) to test the SDM-Q-Doc structure. We calculated the correlations between the SDM-Q-Doc and the Observing Patient Involvement (OPTION) scale, used as comparing test, and McDonald ω coefficient to measure convergent validity and internal consistency respectively.

Results: We reached a response rate of 93.2% (344 final participants). The CFA showed a very good fit compared of the Italian version of SDM-Q-Doc (χ2/df=3.2, CFI=.99, TLI=.99, RMSEA=.08, SRMR=.04). We found several correlations between the SDM-Q-Doc and OPTION scale supporting a robust SDM-Q-Doc construct validity, while internal consistency of the scale was McDonald ω coefficient .92. Further, inter-item correlations ranged from .390 to .703, with a mean of .556.

Conclusions: This study confirms the suitability of the Italian version of SDM-Q-Doc, with good reliability and soundness even when compared to other languages validated versions and to OPTION scale. SDM-Q-Doc represents an easy-to-use physician-centered measure to assess patients' involvement in medical decision-making, well performing in the Italian-speaking population.

在意大利现实世界精神病临床样本中测试共享决策问卷-医师版(SDM-Q-Doc)的心理测量特性。

目的:共同决策问卷-医师版(SDM- q - doc)是从临床医生的角度评估医患之间SDM关系的主要工具。它在所有医学领域都是可靠的，其意大利版本的验证仍然缺失。我们的目的是在患有严重精神疾病的患者的临床样本中验证意大利版的SDM-Q-Doc。方法:我们在现实世界的门诊临床环境中接触了369名患有主要精神障碍(包括精神分裂症谱系障碍、情感障碍和饮食障碍)的患者。我们运行验证性因子分析(CFA)来测试SDM-Q-Doc结构。我们分别计算SDM-Q-Doc与OPTION量表(作为比较检验)和McDonald ω系数(衡量收敛效度和内部一致性)之间的相关性。结果:应答率为93.2%(最终参与者344人)。与意大利版本的SDM-Q-Doc相比，CFA显示出非常好的拟合(χ2/df=3.2, CFI=。99年,TLI =。99年,RMSEA =。08年,SRMR = .04点)。我们发现SDM-Q-Doc与OPTION量表之间存在若干相关性，支持稳健的SDM-Q-Doc结构效度，而量表的内部一致性为McDonald ω系数0.92。此外，项目间相关性从0.390到0.703不等，平均值为0.556。结论:本研究证实了意大利语版SDM-Q-Doc的适用性，即使与其他语言验证版本和OPTION量表相比，也具有良好的可靠性和健全性。SDM-Q-Doc代表了一种易于使用的以医生为中心的措施，用于评估患者参与医疗决策，在意大利语人群中表现良好。
