ABSTRACT
Introduction. Patient-physician relationship is associated with ART adherence and medical follow-up in
people living with HIV (PLWH). Patient’s trust in their doctor is a key component of patient-physician relationship,
so adequate and reliable instruments to measure this component are important to evaluate its
impact on health outcomes.
Objective. To evaluate the psychometric properties of a translated and adapted
version of Trust in Physician Scale (TPS) in Mexican PLWH.
Method. A cross-sectional study was carried
out in PLWH. Scale was translated to Spanish and culturally adapted. Sociodemographic and TPS data
were collected online due to COVID-19 pandemic. Exploratory (EFA) and confirmatory (CFA) factor analysis
were carried out in two different samples.
Results. Data from 215 participants was used to EFA. Five items
were eliminated due to low correlation with total scale. Final Cronbach's alpha was .93. A single-factor structure
explained 68.8% of the variance. CFA in a sample of 140 participants confirmed adequate fit indices
(χ
2[7] = 13.015
p = .072, CFI = .997, RMSEA = .057, SMRS = .0015).
Discussion and conclusion. The final
scale was unifactorial and it is made up of six items instead of 11. It seems to be a valid and reliable scale to
measure patient’s trust in doctors in Mexican PLWH. Further studies are recommended to provide evidence
of convergent validity to the instrument.
