Control of halo error: A multiple regression approach.

Comments on an article by F. J. Landy et al (see record 1981-00274-001) that suggests a method for excluding halo variance in rating scales. It is argued that this approach may result in excluding true variance. The present article presents a conceptualization of the halo effect in terms of a suppressor variable. Accordingly, a multiple regression approach for the treatment of halo variance is suggested. (13 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)
