Background:

Knowledge translation (KT) not only encompasses a series of final actions in areas of dissemination, but also the identification of strategies for the implementation of this process.

Objective:

To evaluate the effectiveness of KT strategies in audiovisual language compared with other languages to improve health outcomes in the general population. Methods: We performed a search in MEDLINE, CENTRAL, PsycARTICLES, the WHO Interna tional Clinical Trials Registry Platform, EMBASE and LILACS.

Results:

We included 63 studies encompassing a broad range of study populations, languages that were compared to audiovisual language and measurement scales for outcomes. These studies presented a high risk of bias and the quality of evidence was not sufficient to draw conclusions about the effectiveness of the evaluated languages for knowledge translation.

Conclusions:

We identified different languages that could be used in knowledge translation. The knowledge and the effects produced as a result of the strategy diminish as time pro gresses, regardless of the type of language used. This is an important point to consider when implementing this type of strategy.
