As an effort to establish linguistic equivalence, which of the following is an accurate description of back translation? It involves taking a research protocol in one language, translating it into the target language, and having someone else translate it back to the original. It is a procedure that involves bilingual informants debating the various forms, words, and phrases to be used while translating a research protocol to a target language. It is a procedure used to establish sampling equivalence. It may involve several bilingual informants collectively translating a research protocol into a target language.

Answer: It involves taking a research protocol in one language, translating it into the target language, and having someone else translate it back to the original.

Explanation:

A linguistic equivalence is achieved when a target language is translated into another language and the translated language includes the same meaning as that in source language.

The back translation is a process in which the source language is translated into another language. Then a separate independent translator is asked to translate the source language and comparison is made between the two translations.

Taking a research protocol in one language and translating it in the format of target language and using another person to translate the source language is indicative of an effort used to establish the linguistic equivalence and it is an effort of back translation.
