Multiple Sources Supporting the Same Evidence or Idea | Multiple recent research studies (Demicheli, Rivetti, Debalini, & Di Pietrantonj, 2012; Jain et al., 2015; Uno, Uchiyama, Kurosawa, Aleksic, & Ozaki, 2015) were unable to replicate Wakefield's findings from the 1998 12-child study published in the Lancet in which Wakefield claimed a correlation between the MMR vaccination and autism. |
1 Important Source and Multiple Other Sources Supporting the Same Evidence |
A positive correlation between social media and political participation is demonstrated in multiple scientific studies (Macafee & De Simone, 2012; see also Ekström, Olsson, & Shehata, 2014; Gil de Zúñiga et al., 2011; Gil de Zúñiga et al., 2013). |
Rule #2: Author(s) & Year of Publication
Each text citation must include at least two pieces of information:
Many times, this information will appear in parentheses like this (Earhart, 2015). However, the same information may appear in other ways. (See examples on this page under Examples by Number of Authors.)
Rule #3: Citing a Specific Idea or Concept
When taking a quotation from a source, always indicate the specific place the quotation comes from, so that readers can find that quotation again easily. Generally, this will mean including the page number(s) in the text citation:
If citing a source that does not include page numbers (such as a website), use either a paragraph number or section header instead of a page number:
Rule #5: AND versus Ampersand (&)
In text citations where et al. is required, do not italicize et al., even though it is the abbreviation of a foreign word – APA considers it to be common enough it scientific writing to not need italics.
When citing a specific part of a source, include the appropriate information such as:
When quoting, always include the page number.
Example 1 | Kinsey stated, “We are recorders and reporters of the facts…” (1953, p. 5). |
Example 2 | Discussing female sexuality, the author proclaims… (Kinsey, 1953, Chapter 9). |
Example 3 |
Data demonstrates that females within specific age and education levels report significantly greater sexual activity than do their male partners (Kinsey, 1953, Table 6). |
For electronic documents that do not have page numbers (such as a website or an article written in HTML that appears as one long page on the screen), give the paragraph number or the section name to indicate what part of the document being referred to. Examples for this table are based on an article from PubMed.
Example 1 | The consequences of risky sexual behaviors among teenagers is a worldwide concern with global implications (Landry, Turner, Vyas, & Wood, 2017, para 1.) |
Example 2 | Landry, Turner, Vyas, and Wood required participants to track how often they texted friends, family, and romantic partners (2017, Methods). |
Example 3 |
This study determined that adolescents are exposed to increased pressure to engage in risky sexual behaviors due to increases in social media participation (Landry, Turner, Vyas, & Wood, 2017, Discussion, para. 2). |
