Individuals with voice disorders may experience limits in activity and restricted participation in daily activities. The aim of this study was to investigate the psychometric properties of the Voice Activity Participation Profile-Persian Version (VAPPP), a questionnaire which specifically investigates activity limitation and participation restriction in Persian-speaking individuals with voice disorders.
We completed a translation procedure according to World Health Organization guidelines, prior to administering the questionnaire to 208 participants (156 patients with dysphonia and 52 controls), each of whom completed the questionnaire. We examined various psychometric properties including item analysis, factor analysis, internal consistency, discriminant validity, criterion-related validity, and test-retest reliability were investigated for this questionnaire.
Confirmatory factor analysis revealed that the 27 items on the VAPPP were distributed across four factors and that the first question, which assesses self-perceived dysphonia severity, was grouped separately. All the four subscales and total VAPPP have high internal consistency and test-retest reliability based on Cronbach's alpha coefficients and the intraclass correlation coefficient (ICC). Job effects (α = 0.85; ICC = 0.96), daily communication effects (α = 0.96; ICC = 0.83), social communication effects (α = 0.91; ICC = 0.93), emotional effects (α = 0.94; ICC = 0.76), and total score (α = 0.97; ICC = 0.88) are presented. VAPPP scores in patients with dysphonia were significantly different from those of the healthy control group (P < 0.001). The VAPPP total score has a high correlation to the Voice Handicap Index (r = 0.86; P < 0.001) CONCLUSION: The VAPPP is a reliable and valid tool for evaluating the quality of life of patients with dysphonia in Iran.
嗓音障碍患者可能在活动方面受到限制，并且在日常活动中的参与度也会受限。本研究的目的是调查《嗓音活动参与概况-波斯语版》（VAPPP）的心理测量特性，这是一份专门针对讲波斯语的嗓音障碍患者的活动受限和参与受限情况进行调查的问卷。
在向208名参与者（156名发音障碍患者和52名对照者）发放问卷之前，我们按照世界卫生组织的指南完成了翻译程序，每位参与者都填写了问卷。我们研究了该问卷的各种心理测量特性，包括项目分析、因子分析、内部一致性、区分效度、效标关联效度以及重测信度。
验证性因子分析表明，VAPPP上的27个项目分布在四个因子中，并且评估自我感知的发音障碍严重程度的第一个问题单独分组。基于克朗巴哈系数和组内相关系数（ICC），所有四个子量表和VAPPP总分都具有较高的内部一致性和重测信度。列出了工作影响（α = 0.85；ICC = 0.96）、日常沟通影响（α = 0.96；ICC = 0.83）、社交沟通影响（α = 0.91；ICC = 0.93）、情感影响（α = 0.94；ICC = 0.76）以及总分（α = 0.97；ICC = 0.88）。发音障碍患者的VAPPP得分与健康对照组的得分有显著差异（P < 0.001）。VAPPP总分与嗓音障碍指数高度相关（r = 0.86；P < 0.001）。结论：VAPPP是评估伊朗发音障碍患者生活质量的可靠且有效的工具。
