Citing translated sources in APA style


If a source is in another language, write the original title then add its English translation in square brackets as the below example:

Grangeat, M. (2011) (Ed.). Les demarches d’investigation dans l’enseignement scientifique pratiques de classe, travail collectif enseignant, acquisitions des eleves. Ecole Normale Supérieure.

should be written as,

Grangeat, M. (2011) (Ed.). Les démarches d’investigation dans l’enseignement scientifique pratiques de classe, travail collectif enseignant, acquisitions des élèves [Investigative approaches in science teaching class practices, collective teacher work, student acquisitions]. Ecole Normale Supérieure.

Here is an example of an article in a journal.

Bussieres, E.-L., St-Germain, A., Dube, M., & Richard, M.-C. (2017). Efficacite et efficience des programmes de transition a la vie adulte: Une revue systematique [Effectiveness and efficiency of adult transition programs: A systematic review]. Canadian Psychology/ Psychologie canadienne, 58(1), 354–365.

Here’s another example, from a German journal. Again, brackets contain an English translation of the work’s title (the article, not the journal).

Janzen, G., & Hawlik, M. (2005). Orientierung im raum: Befunde zu entscheidungspunkten [Orientation in space: Findings about decision points]. Journal of Psychology/ Zeitschrift für Psychologie, 213(4), 179–186.

Here’s how you would cite the original French edition of a work by Piaget (note that an English translation of the title is included in brackets):

Piaget, J. (1966). La psychologie de l’enfant [The psychology of the child]. Presses Universitaires de France. 

If you read an English translation of a foreign work, by including translator:

Piaget, J. (1969). The psychology of the child (H. Weaver, Trans.).  Basic Books. (Original work published 1900)

  • In-text citation: (Piaget, 1900/1969)
