Hyphenate self?

Hyphenate self?

Yes, please! At least if you're following APA style. Per APA p. 100 (sixth edition) all self prefixes will be hyphenated. For example:

Self-efficacy

Self-published

Self-promotion

Not every style guide follows this rule but I'm a fan. If you're not following a particular style guide, why not follow APA? Full hyphen rules can be found on APA pp. 99-101 and at this link.
