Psychometric instruments can quantify how people living with HIV experience three key barriers to antiretroviral therapy (ART) and retention: partner support, trust in medical professionals, and internalized HIV-related stigma. However, two challenges arise when using these instruments to measure and interpret relational processes among Mozambican couples, especially those participating in a couples intervention. First, relational measures have almost exclusively been developed and normed with Western, middle-class, and/or White adults. Second, traditional measurement approaches neglect the relational processes between partners. Using dyadic modeling, this paper demonstrates metric and scalar invariance for instruments measuring partner support (CFI = 0.964, TLI = 0.965, RMSEA = 0.034, SRMR = 0.052), trust in medical professionals (CFI = 0.978, TLI = 0.980, RMSEA = 0.033, SRMR = 0.039), and internalized HIV-related stigma (CFI = 0.960, TLI = 0.961, RMSEA = 0.050, SRMR = 0.060) within the novel context of seroconcordant HIV+ couples in Zambézia province.
心理计量工具可以量化艾滋病毒感染者在接受抗逆转录病毒治疗（ART）和保留方面所面临的三个关键障碍：伴侣支持、对医疗专业人员的信任以及内化的艾滋病毒相关耻辱感。然而，当使用这些工具来衡量和解释莫桑比克夫妇之间的关系过程，特别是那些参与夫妇干预的夫妇时，会出现两个挑战。首先，关系衡量标准几乎完全是为西方中产阶级和/或白人成年人开发和制定的。其次，传统的测量方法忽视了伴侣之间的关系过程。本文通过对偶模型，证明了衡量伴侣支持（CFI=0.964，TLI=0.965，RMSEA=0.034，SRMR=0.052）、对医疗专业人员的信任（CFI=0.978，TLI=0.980，RMSEA=0.033，SRMR=0.039）和内化的艾滋病毒相关耻辱感（CFI=0.960，TLI=0.961，RMSEA=0.050，SRMR=0.060）的工具在赞比西亚省血清一致的艾滋病毒+夫妇这一新背景下具有度量和标度不变性。
