To know the dimensionality and internal consistency of the Tuberculosis-Related Stigma Scale in patients living with tuberculosis in Santa Marta, Colombia.
One hundred and twenty-two patients between the ages of 18 and 75 participated ( = 40.3, SD = 14.9), 63.9% were men, 44.3% were single, 69.7% had low income, 80.3% had pulmonary tuberculosis, and 13.1% had co-infection with HIV. The Tuberculosis-Related Stigma Scale was applied; it comprises perceived and internalised stigma subscales. The internal structure was explored by confirmatory factor analysis (EFA). Internal consistency was measured with Cronbach's alpha and McDonald's omega. Besides, the differential functioning of the scales according to gender was explored with Kendall's tau-b coefficient.
CFA did not show excellent goodness-of-fit indicators for the perceived stigma scale (Satorra-Bentler's chi-square of 184.48, degree of freedom of 44, = .001, RMSEA of 0.16, 95%CI 0.14-0.19, CFI of 0.77, TLI of 0.72, and SRMR of 0.08) and internalised (Satorra-Bentler's chi-square of 189.14, degree of freedom of 54, = .001; RMSEA of 0.14, 95%CI 0.12-0.17, CFI of 0.82, TLI of 0.78, and SRMR of 0.07). The alpha and omega coefficients were 0.89 and 0.91 for both scales. Non-gender differential functioning was observed; Kendall's tau-b was between 0.00 and 0.15.
The Tuberculosis-Related Stigma Scale has an excellent internal consistency but poor goodness-of-fit indicators of unidimensionality. Evaluating the scale's psychometric performance is recommenced in future research.
了解哥伦比亚圣玛尔塔结核病患者的结核病耻辱感量表的维度和内部一致性。
122 名年龄在 18 至 75 岁之间的患者参与了这项研究（ = 40.3，SD = 14.9），其中 63.9%为男性，44.3%为单身，69.7%收入较低，80.3%患有肺结核，13.1%合并 HIV 感染。应用结核病耻辱感量表；它包括感知和内化的耻辱感子量表。通过验证性因素分析（EFA）探索内部结构。用 Cronbach's alpha 和 McDonald's omega 测量内部一致性。此外，还通过 Kendall's tau-b 系数探讨了根据性别对量表的差异功能。
验证性因素分析未显示感知耻辱感量表（Satorra-Bentler 的卡方值为 184.48，自由度为 44， = .001，RMSEA 为 0.16，95%CI 为 0.14-0.19，CFI 为 0.77，TLI 为 0.72，SRMR 为 0.08）和内化耻辱感量表（Satorra-Bentler 的卡方值为 189.14，自由度为 54， = .001；RMSEA 为 0.14，95%CI 为 0.12-0.17，CFI 为 0.82，TLI 为 0.78，SRMR 为 0.07）的拟合优度指标良好。两个量表的 alpha 和 omega 系数分别为 0.89 和 0.91。观察到非性别差异功能；Kendall's tau-b 值在 0.00 到 0.15 之间。
结核病耻辱感量表具有极好的内部一致性，但维度的拟合优度指标较差。建议在未来的研究中评估该量表的心理测量性能。
