Content validity of the scale Perceptions on Interpersonal Racial Discrimination in Brazilian Healthcare Facilities (Driss)

Abstract

Aiming to elaborate and assess the content validity
of the new scale Perceptions on Interpersonal
Racial Discrimination in Brazilian Healthcare
Facilities (Driss), we conducted a methodological
study based on the Classical Test Theory. Initially,
we had a pool of 49 items based on a comprehensive
literature review, previous qualitative study, and
recommendations from a research group on ethnicracial inequalities. To assess content validity,
an experts committee was formed. Qualitative
and quantitative criteria were used to ensure
methodological rigor. After the evaluation of the
Driss version 1 by the experts committee, 28 items
were excluded; 10 others were fragmented and/
or modified. Thus, Driss version 2 was developed
and subjected to pre-test, which showed a need to
include introductory questions to make it better
understood by the target population regarding
the objectives of the study. Subsequently, we
elaborated Driss version 3, whose content aims
to value perceptions and feelings experienced by
individuals who suffered racial discrimination
at healthcare facilities. The content validity of
version 3 was assessed by the Content Validity
Ratio, being considered satisfactory and ready for
later construct validity valuation.
