Cultural adaptation and content validation of the Single-Question for screening alcohol abuse

Abstract

Objective Describing the stages of translation, cultural adaptation and content validation of the Single-Question into Brazilian Portuguese, which will be named Questão Chave. Method This study is a cultural adaptation. The instrument was translated into Portuguese as two independent versions which led to a synthesis of translations (S1), and later to the synthesis S2, which was then submitted to evaluation by a Committee of Expert Judges in the area of alcohol use and instrument validation. The Content Validity Index and Kappa agreement coefficient were calculated from this evaluation. Results The judges evaluated the Questão Chave regarding the clarity of the sentence and aspects related to the quality of the translation (cultural adaptation, preservation of original meaning and correct use of technical terms). The Content Validity Index was 1 for clarity of sentence and correct use of technical terms, and 0.8 for adaptation and preservation of the original meaning. The Kappa index for concordance among the judges was 0.83. After an adjustment proposed by the judges, the S3 version was originated. Conclusion The Questão Chave had its content validity confirmed, which supports future studies that aim for its application in the target population to verify their psychometric properties.

Criterion validity of the Key Question for screening at-risk alcohol use in primary healthcare

“…This is a psychometric validation study of the Key Question (QC) criterion (8) . Criterion validity can be defined as the correlation between the measure to be tested and a pre-established external criterion measure (17) .…”

“…The QC was applied after adaptation and content validation, with the final Portuguese version being presented as: "How many times in the last 12 months have you drunk X or more doses of alcohol in 1 day?" (8) , where X is 5 for men and 4 for women. According to the parameters for at--risk alcohol use, screening is considered positive when the response is 1 or more times (14) .…”

“…There are currently some instruments available and validated for this purpose in Brazil, but which do not meet all the characteristics mentioned above in a single instrument, despite having reliable psychometric aspects. Some instruments have an excessive number of questions, which requires more consultation time for their application and costs with the production of materials (8) ; they do not take gender differences into account when establishing equal risk dose parameters for both men and women (9) ; they are restricted to specific populations (10)(11) ; and finally they are not sensitive to evaluate the at-risk use, only the later stages of alcohol--related disorders (12)(13) , and are therefore not indicated for use in PHC.…”

“…Thus, the Single-Question was translated into Portuguese and culturally adapted in Brazil, being called the "Key Question" (Questão-Chave -QC) (8) . Considering that the criterion validity evidence of the Key Question in Portuguese has not yet been tested, this study aims to validate the criteria of the Key Question in Portuguese for screening at-risk alcohol use among users of primary healthcare services.…”

“…A Single Question (SQ), traduzida e validada em estudo que denomina a SQ como Questão-chave (QC) e explica que esta apresentou boa concordância entre os juízes em relação ao conteúdo e com desempenho psicométrico (Maciel e Vargas, 2017). (Henrique, Micheli, Lacerda e Formigoni, 2004).…”
