Overall job satisfaction: how good are single-item measures?
A meta-analysis of single-item measures of overall job satisfaction (28 correlations from 17 studies with 7,682 people) found an average uncorrected correlation of .63 (SD = .09) with scale measures of overall job satisfaction. The overall mean correlation (corrected only for reliability) is .67 (SD = .08), and it is moderated by the type of measurement scale used. The mean corrected correlation for the best group of scale measures (8 correlations, 1,735 people) is .72 (SD = .05). The correction for attenuation formula was used to estimate the minimum level of reliability for a single-item measure. These estimates range from .45 to .69, depending on the assumptions made.
