APA Style 6th Edition Blog: Hyphenation
blog.apastyle.org › apastyle › hyphenationOct 05, 2016 · A hyphen is usually used in APA Style when two or more words modify a common noun (and that noun comes after the modifiers), for example, 7-point scale or client-centered counseling. When multiple modifiers have a common base, the base can be omitted in all except the last modifier, but the hyphens should be retained.
