Hi Emonet,
I am writing to let the EI researchers know about a new meta-analysis describing the relation between EI and job performance, recently published in the Journal of Applied Psychology. This meta-analysis (by Joseph, Jin, Newman, and O'Boyle) updates two previous meta-analyses (by Joseph & Newman, 2010, and O'Boyle et al., 2011), and resolves the discrepancy between them.
The new meta-analytic estimates of the EI-job performance relationship (from Joseph, Jin, Newman, & O'Boyle) are:
Mixed EI-Job Performance (supervisor-rated): r = .23, r_corrected = .29
Ability EI- Job Performance (supervisor-rated): r = .17, r_corrected = .20
Mixed EI-Job Performance (objective/results perf.): r = .16, r_corrected = .17
Beyond the meta-analytic updates, the paper also advances one explanation for why Mixed EI measures predict job performance more strongly than Ability EI measures do. We provide an indirect test of the idea that Mixed EI measures, on average, have likely borrowed/sampled some content from measures of other well-known psychological constructs (e.g., Emotional Stability, Extraversion, Self-Rated Performance, General Self-Efficacy). After controlling for measures of these other psychological constructs, the Mixed EI-job performance relationship goes to zero.
FYI,
Dan
