Emotional learning has become an important part of professional development. The problem, however, concerns the limited understanding of the effects of emotional intelligence (EQ) training for individuals in business settings. Emotional intelligence served as the theoretical basis for this research. The purpose of this nonrandomized quasi-experimental study was to examine whether an organization's EQ training curriculum, "EQ Connections," could improve ratings on the EQi-2.0 self-assessment instrument. Participants included 29 managers from a nonprofit organization in Florida. Participants were randomly assigned to the "EQ Connections" treatment group (n = 18) and a control group (n = 11), with each group completing the EQi-2.0 at pretest, posttest, and again at 2-week follow-up. Applying a two-way mixed ANOVA results demonstrated that the between-subjects variable of the group was not significant (p = 0.772, [eta-squared] = 0.003; small effect). The within-subjects variable of time was significant (p = 0.023, [eta-squared] = 0.142; large effect). The interaction effect was not significant (p = 0.124, [eta-squared] = 0.078; medium effect). A Pearson product-moment correlation was conducted to investigate the relationship between managers' years of experience and their EQi-2.0 scores. The results showed a small, nonsignificant positive correlation at pretest for years of experience with the manager's pretest score (r = 0.22). There was not a significant difference between treatment and control groups, but there was a significant gain over time between groups. Evidence for the relationship between managers' years of experience and EQ was weak, with approximately 5% of the variance explained by the relationship at pretest. To examine whether EQ buffers job-related stress and enhance employee engagement, future studies should consider including community practice models. In addition, feedback and self-reflection should be incorporated to improve EQ self-awareness. [The dissertation citations contained here are published with the permission of ProQuest LLC.
