Convention for narrative citations of multiple authors in APA style?

Sorry, this isn’t the most fascinating question, but… I’m writing a short psychological paper for my Masters and I need to reference a journal article that has six authors. The usual resource I use for APA style guidelines states that for multiple authors (three, four or five), that in the first narrative citation, write all surnames in full and then use “et al.” for subsequent mentions. Pretty obvious, but annoyingly, I need to reference a paper authored by six people and I don’t know how I should do this – is it correct to treat it just how I would if it was a three/four/five author paper?
