Lancet Digital Health: Effectiveness of digital psychological interventions for mental health problems (3) Languages other than English (2)

3 March, 2021

Dear Carmen,

You ask: "I wonder if all the study subjects spoke English or the same language or why the language variable is not mentioned...."

To the authors' credit, they did not apply language barriers to their literature search. Also, they translated their summary into multiple languages.

On the other hand, they note: 'Because of language barriers, local literature in LMICs was excluded, which could have biased our results.' How they define 'local literature' is not clear. I have invited to the authors to join us.
