Abstract

Introduction: Appropriate information about the ability of patients with Parkinson disease (PD) to perform cognitive instrumental activities of daily living (IADL) is necessary. The present study aimed to assess the psychometric properties of the Persian version of the Penn Parkinson daily activities questionnaire-15 (PDAQ-15).

Methods: A total of 165 knowledgeable informants of PD patients completed the PDAQ-15. The clinical dementia rating scale, Hoehn and Yahr staging, hospital anxiety and depression scale (HADS), and Lawton IADL scale were used in the study. Internal consistency and test-retest reliability were evaluated by the Cronbach α coefficient and intraclass correlation coefficient (ICC), respectively. To examine the dimensionality of the questionnaire, exploratory factor analysis was used. The construct validity was assessed using the Spearman rank correlation test. To assess the discriminative validity, PDAQ-15 scores were compared across cognitive stages.

Results: The PDAQ-15 showed strong internal consistency (the Cronbach α=0.99) and test-retest reliability (ICC= 0.99). Only one dimension was identified for the PDAQ-15 in the factor analysis. There was a strong correlation between PDAQ-15 with the depression domain of the HADS scale and the Lawton IADL scale (rs=|0.71-0.95|). The correlation of PDAQ-15 with the anxiety domain of the HADS scale was moderate (rs=0.66). Discriminative validity analysis showed that the PDAQ-15 has significant power to discriminate between PD patients across cognitive stages.

Conclusion: These results suggest that the PDAQ-15 is a valid and reliable PD-specific instrument and can be useful in clinical and research settings.

波斯版Penn Parkinson日常活动问卷的心理测量特性-15。

引言：关于帕金森病（PD）患者进行日常生活认知工具活动（IADL）的能力的适当信息是必要的。本研究旨在评估波斯版Penn Parkinson日常活动问卷-15（PDAQ-15）的心理测量特性。方法：共有165名知情的PD患者填写了PDAQ-15。研究中使用了临床痴呆评分量表、Hoehn和Yahr分期、医院焦虑和抑郁量表（HADS）和Lawton IADL量表。内部一致性和重测信度分别通过Cronbachα系数和组内相关系数（ICC）进行评估。为了检验问卷的维度，使用了探索性因素分析。使用Spearman秩相关检验来评估结构的有效性。为了评估辨别有效性，对不同认知阶段的PDAQ-15评分进行了比较。结果：PDAQ-15具有很强的内部一致性（Cronbachα=0.99）和重测信度（ICC=0.99）。在因子分析中，PDAQ-15只有一个维度。PDAQ-15与HADS量表的抑郁域和劳顿IADL量表之间有很强的相关性（rs=|0.71-0.95|）。结论：PDAQ-15是一种有效、可靠的PD特异性仪器，可用于临床和研究环境。

期刊介绍： BCN is an international multidisciplinary journal that publishes editorials, original full-length research articles, short communications, reviews, methodological papers, commentaries, perspectives and “news and reports” in the broad fields of developmental, molecular, cellular, system, computational, behavioral, cognitive, and clinical neuroscience. No area in the neural related sciences is excluded from consideration, although priority is given to studies that provide applied insights into the functioning of the nervous system. BCN aims to advance our understanding of organization and function of the nervous system in health and disease, thereby improving the diagnosis and treatment of neural-related disorders. Manuscripts submitted to BCN should describe novel results generated by experiments that were guided by clearly defined aims or hypotheses. BCN aims to provide serious ties in interdisciplinary communication, accessibility to a broad readership inside Iran and the region and also in all other international academic sites, effective peer review process, and independence from all possible non-scientific interests. BCN also tries to empower national, regional and international collaborative networks in the field of neuroscience in Iran, Middle East, Central Asia and North Africa and to be the voice of the Iranian and regional neuroscience community in the world of neuroscientists. In this way, the journal encourages submission of editorials, review papers, commentaries, methodological notes and perspectives that address this scope.
