My understanding is that self-report measures of emotional intelligence tend to have very weak correlations with traditional measures of cognitive ability, and ability-based measures of emotional intelligence have low to moderate correlations with traditional measures of cognitive ability. The following provides relevant extracts from Conte (2005) that directly relates to these points. For a more complete picture you may wish to read the article.
Self-report measures of emotional intelligence
The EQ-i is a 133-item self-report measure that takes approximately 30 minutes to complete (Bar-On, 2000) ...
With respect to discriminant validity, the EQ-i correlated 0.12 with
the Wechsler Adult Intelligence Scale (Bar-On, 2000), and the average
correlation between the EQ-i and the Big Five personality measures was
approximately 0.50 (Dawda & Hart, 2000)
Ability based measures of emotional intelligence
The MEIS and MSCEIT are both ability based measures of emotional intelligence.
Data from several studies indicate that the MEIS correlates between 0.30 and 0.40 with traditional measures
of cognitive ability (Roberts et al., 2001; Van Rooy & Viswesvaran, 2004)
Relation between ability and personality based measures
It also appears that self-report and ability based measures of emotional intelligence are measuring relatively distinct variables.
Mayer et al. (2000) found that the MSCEIT and Bar-On scales correlated
0.36, indicating that they share approximately 13 percent of their variance.
In a more recent study, Brackett and Mayer (2003) found that
the MSCEIT and Bar-On scales correlated 0.21, indicating that they
share approximately 4 percent of their variance.
