A Guideline on APA (American Psychological Association) Style

Spacing  Double-spacing is required throughout most of the manuscript.  Single spacing can be used for table titles and headings, figure captions, references (but double-spacing is required between references), footnotes, and long quotations.  Space once after commas, colons, semicolons, and punctuation marks at the end of sentences

Text Details  Make sure the text is left aligned and not justified.  Footnotes are rarely used in APA papers.  Use a 12 point font.  Indent 5-7 spaces (one-half inch, 1.25 cm) within paragraphs.

Text Details  Margins should be 0.98” all around.  Page numbers are required on every page (top of the page and right alignment).  The page header summarizes the title in a few words.  Use header top left corner; font size xx  No spacing between the paragraphs

Headings  Level 1- Centered Uppercase and Lowercase Heading  Level 2- Centered, Italicized, Uppercase and Lowercase Heading  Level 3 – Flush left, Italicized, Uppercase and Lowercase  Level 4- Indented, Italicized, lowercase  Level 5- CENTERED UPPERCASE HEADING

Headings  APA headings follow a complex hierarchy, with provision for up to five levels. These come, in descending order, as levels 5, 1, 2, 3, 4. But, if one, two, or three levels of headings are required in a paper, use levels 1, 3, and 4, in that order. If four levels are required, interleave level 2 between levels 1 and 3. If five levels are required, start with level five and work down the remaining hierarchy in order (5, 1, 2, 3, 4).

Commas  Use commas before "and" in lists.  Use commas between groups of three digits, for example, 1,453.  Use commas to set off a reference in a parenthetical comment (Patrick, 1993).  Use commas in exact dates, for example, April 18, 1992 (but not in April 1992).

Italics (Underlining)  Do not italicize or underline common foreign abbreviations (vice versa, et al., a priori).

Quotation Marks  For quotations over 40 words in length, indent and single space the whole block.

Abbreviations  Explain what an abbreviation means the first time it occurs: American Psychological Association (APA).

Numbers  Use digits to express numbers 10 and above.  Use words to express numbers below 10.  Use digits to represent statistical or mathematical functions, fractional or decimal quantities, percentages, ratios, and percentiles.  Use digits to represent time, dates, ages, sample or population size, scores, and exact sums of money.

Tables and Figures  Type the table number and then (on the next double spaced line) type the table title flush left and italicized.  Each row and column must have a heading.  Use a zero before the decimal point when numbers are less than one.  Add notes to explain the table contents.

Figures  Center each figure on the page.  Italicize the word 'figure' and the number, for example, Figure 1. The effects of...

Reference Citations (In- Text)  Examples include Some fact (last name, year)., Last name (year) noted that...  For two-author citations, spell out both authors on all occurrences. For example: As Smith and Sarason (1990) point out, the same argument was made by in an earlier study (Smith & Sarason, 1990).  For multiple-author citations (up to five authors) name all authors the first time, then use et al., so the first time it is Smith, Jones, Pearson, and Sherwin (1990), but the second time it is Smith et al.

Reference Citations (In- Text)  If citing multiple works by the same author at the same time, arrange dates in order. For example: Several studies (Johnson, 1988, 1990a, 1990b).  Multiple citations in parentheses are placed alphabetically and are separated by a semicolon and a space. For example, Some fact (Carlson, 1972; Moon, 1968; Partin, 1980).

Reference Formats For Back Page  Alphabetize the reference list by authors’ last names.  Use a hanging indent for references (all lines after the first line of each entry in the list should be intended one-half inch from the left margin). Example- Deutsch, F. M., Lussier, J. B., & Servusm L. J. (1993). Husbands at home: Predictors of parentalparticipation in childcare and housework. Journal of Personality and Social Psychology, 65,  If you have more than one work by an author, order them by publications date, oldest to newest  When an author appears both as a sole author and, in another citation, as the first author of a group, list the one author entries first

Reference Formats For Back Page  If no author is given for a source, alphabetize using the title of the work, which will be listed in place of the author.  Use “&” instead of “and” when listing multiple authors of a single work.  Italicize titles of books and journals.
