Emotional intelligence refers to the competence to identify and express emotions, understand emotions, assimilate emotions in thought, and regulate both positive and negative emotions in the self and in others. Although EI has generated much research, until recently it has been overlooked that different measurement approaches of EI are investigating related, but different constructs (Petrides & Furnham, 2000). Trait EI or "emotional self-efficacy" is measured via self-reports, and ability EI or "cognitive-emotional ability" is measured via "objective" tests. The aim of this research was to estimate upper-limit heritability of trait EI using a family design. It was expected that it would be in accordance with heritability typically found for other personality traits, given that trait EI is located at the primary levels of established hierarchical trait structures. The sample consisted of high school students (N=133), and one or both of their parents. Both offspring and their parent(s) completed self-report measure of EI: TEIQue, which is supposed to include all important facets of EI. For global score, father - offspring correlation was .09 and statistically no significant, while mother - offspring correlation was significant, r =.22, which yields estimate of 44% for the upper limit of h". The regression of offspring on midparent score was .30. Mother - father correlation was not found. Two-way ANOVA showed gender, but no generation differences on global score. Overall, findings are in line with hypothesis, but due to limitations of this study (very small sample size, and overrepresentation of female participants), it is likely that results are biased. Further research with bigger sample which would allow separate analysis by gender is needed.
