I've been looking for some information on how to cite an indirect source with multiple authors in APA format and found this explanation on the following website: http://www.umuc.edu/library/libhow/apa_examples.cfm#secondary
Citing a Source within a Source (Publication Manual, p. 178)
Scenario: You read a 2007 article by Linhares and Brum that cites an earlier article, by Frederick. You want to cite Frederick's article, but you have not read Frederick's article itself.
|Reference List Citation||In-Text Citation|
Linhares, A., & Brum, P. (2007). Understanding our understanding of strategic scenarios: What role do chunks play? Cognitive Science, 31(6), 989-1007. http://dx.doi.org/doi:10.1080/03640210701703725
Your Reference list will contain the article you read, by Linhares and Brum. Your Reference list will NOT contain a citation for Frederick's article.
Frederick's study (as cited in Linhares & Brum, 2007) found that...
Your in-text citation gives credit to Frederick and shows the source in which you found Frederick's ideas.
As you can see, the citation is treated like any other citation with multiple authors. In the Reference list, you will only cite the article or book that you used, the one that referred to the indirect source. For the in-text citation, you'll add as cited in before the author's names and pub. date.
If you look at the example and explanation of the in-text citation I think it will explain your question about the use of "in". It is used to show the source in which you found the reference to the original author's work. So, in the example you gave in your question, Smith is the author of the article that you read. They say "in" because they are telling you that the original author's work was cited in Smith's work.
I hope this helps you! Let me know if you have further questions.
