Abstract

Objectives: Disease-related stigma is associated with poor mental health and wellbeing in people with Parkinson's disease. Urdu language tools for measuring stigma are not yet available. The aim of this study was therefore to develop and validate an Urdu version of the Stigma Scale for Chronic Illness-8 (SSCI-8).

Method: The Urdu SSCI-8 was developed following the 'Functional Assessment of Chronic Illness Therapy' translation procedure. To assess its reliability and validity, 250 people diagnosed with Parkinson's disease, aged 50-65 years, completed the Urdu SSCI-8, along with Urdu versions of depression and quality of measures.

Results: Confirmatory Factor Analysis revealed that a single factor solution provided a good fit to the data, with high internal consistency (Cronbach Alpha = 0.95), and good fit indices (RMSEA = 0.05, CFI = 0.99, TLI = 0.98, GFI = 0.96). Composite Reliability Co-efficient (0.95) and Average Variance Extracted (0.71) values indicated strong convergent reliability and validity. Scores on the Urdu SSCI-8 correlated positively with depression (r = 0.53, p < 0.001), and negatively with quality of life (r = -0.61, p < 0.001), indicating high levels of convergent and discriminant validity.

Conclusion: The Urdu SSCI-8 is a reliable, valid, and culturally appropriate tool for measuring stigma among patients with Parkinson's disease.

8项慢性疾病乌尔都病耻感量表（ssi -8）在帕金森病患者中的心理计量学验证

目的：疾病相关的耻辱感与帕金森病患者的心理健康和福祉状况不佳有关。乌尔都语还没有用来衡量耻辱的工具。因此，本研究的目的是开发和验证乌尔都语版本的慢性疾病病耻感量表-8 （ssi -8）。方法：根据《慢性疾病治疗功能评估》翻译程序编制乌尔都语ssi -8量表。为了评估其可靠性和有效性，250名年龄在50-65岁之间被诊断患有帕金森病的人完成了乌尔都语ssi -8，以及乌尔都语版本的抑郁和测量质量。结果：验证性因子分析显示，单因素溶液与数据拟合良好，具有较高的内部一致性（Cronbach Alpha = 0.95），拟合指数良好（RMSEA = 0.05, CFI = 0.99, TLI = 0.98, GFI = 0.96）。复合信度系数（0.95）和平均方差提取（0.71）值表明信度和效度具有较强的收敛性。乌尔都ssi -8的得分与抑郁呈正相关（r = 0.53, pr = -0.61, p）结论：乌尔都ssi -8是一种可靠、有效、文化上合适的测量帕金森病患者病耻感的工具。
