Resumen:
Background: Studies among the Mexican population have suggested that
stigma towards persons who use drugs (PWUD) may act as a barrier to
treatment seeking and contribute to negative health consequences.
However, there has not been a validated scale to measure this construct.
This paper aims to validate the Substance Use Stigma Mechanisms Scale
(SU-SMS) in a sample of Mexican adults who use drugs. This 18-item scale
was developed to differentiate substance use stigma mechanisms and learn
their impact on the health and wellbeing of persons who use drugs (PWUD)
in the United States. Methods: A sample of 407 adults with a median age
of 27 years old completed a web-based version in Spanish of the SU-SMS,
the WHO-ASSIST screening instrument, as well as sociodemographic and
substance-use-related characteristics. We performed exploratory factor
analysis with weighted least squares and oblique rotation, and
correlations within and between mechanisms of stigma, and substance use.
Results: The Spanish translation of the SU-SMS has adequate internal
consistency (ohm=0.92) and the same factor structure as the original
scale. A five-factor solution with internalized, enacted, and
anticipated stigma from family and healthcare workers showed adequate
concurrent validity. Mechanisms of stigma were correlated between them,
within sources, and negatively correlated with current substance use
treatment. Conclusions: The Spanish translation of the scale seems to be
a valid and sensitive scale that can be used among Mexican PWUD.
