When to include the year in citations appearing more than once in a paragraph

by Tyler Krupa

You may already know that references in APA Style are cited in text with an author–date system (e.g., Smith, 2012). But do you know when to include the year of publication when one of your citations appears more than once in a paragraph? Getting it right is simple as long as you remember the following two guidelines:

1. All parenthetical citations (i.e., citations in which both the author name and publication date are enclosed within parentheses) should include the year, regardless of how often they appear in a paragraph.

2. When the name of the author is part of the narrative and appears outside of parentheses, after the first citation in each paragraph you need not include the year in subsequent nonparenthetical citations as long as the study cannot be confused with other studies in the article (see p. 174 in the sixth edition of the Publication Manual).

To help illustrate these guidelines, let’s look at a few examples that correctly show when to include the year in citations appearing more than once in a paragraph:

Morin (1988) described two separate but linked epidemics. . . . Morin distinguished the HIV (viral) epidemic from the subsequent AIDS (disease) epidemic, foreseeing the ultimate convergence of preventing the spread of the virus and managing the disease it causes. . . . Morin also discussed a third epidemic . . . . This third epidemic is as much a part of the pathology of AIDS as the virus itself (Morin, 1988).Socioeconomic status (SES) and chronic diseases rather consistently fall on a gradient, where those of relatively lower SES have poorer health and are more often afflicted by multiple diseases than those above them on the SES ladder (Adler & Stewart, 2010). . . . Adler and Stewart (2010) offered a framework to explain the major pathways by which SES can influence health outcomes. . . . The model is developmental, illustrating individual, social, and structural influences on disease over the lifespan (Adler & Stewart, 2010).
