We tested the hypothesis that structural integration, as assessed in the Operationalized Psychodynamic Diagnosis (OPD) system, and emotional intelligence (EI), as studied in personality psychology, might be closely related constructs at a general level, as both might assess general personality functioning. In three studies (n ₁ = 166, n ₂ = 204, n ₃ = 349), we used a self-report measure of OPD structural integration and measures of Trait and Ability EI. Structural integration and Trait EI display very high correlation at general factor level (r =.77 -.82) and almost perfect latent correlation (r =.85 -.90). This correlation cannot be explained away by the general positivity of self-views or socially desirable responding. There is also substantial latent correlation between structural integration and Ability EI (r =.20 -.65). Results replicate over different samples from different countries and extend to the DSM-5 self-report personality functioning scale.
