Purpose of the Questionnaire (Scale)

The EKSN was designed to assess emotional intelligence in adolescents and adults within the Greek-speaking population. It is aimed at psychologists, educators, and researchers, with the main objective of measuring the ability to recognize, understand, manage, and regulate emotions. The scale is used in both clinical and research settings, with applications in educational and workplace contexts.

Questionnaire (Scale) Analysis

The scale was developed by Tsaousis and Kotzamanis (2004) and is based on the emotional intelligence models of Goleman (1995) and Mayer & Salovey (1997). It consists of 40 self-report statements organized into 4 main subscales: Self-Awareness (10 items), Emotional Regulation (12 items), Social Sensitivity (10 items), and Relationship Management (8 items).

Scoring of the Items

Responses are rated on a 5-point Likert scale (1 = Not at all to 5 = Very much). The final score is calculated as follows: Total score (40–200), subscale scores, and standardized scores (M = 100, SD = 15).

Statistical Analysis

The scale has been standardized on a sample of 1,200 Greeks (aged 15–65). Statistical indicators show internal consistency (α = 0.89 for the total scale), test-retest reliability (r = 0.82 over a 4-week interval), and correlations with other emotional intelligence instruments (r = 0.65–0.75).

Validity of the Questionnaire (Scale)

The validity of the EKSN has been confirmed through correlational studies with other emotional intelligence tools, discriminant ability between professional groups, and factor analysis confirming the theoretical structure.

Reliability of the Questionnaire (Scale)

The scale demonstrates high reliability, with internal consistency (α = 0.85–0.90 for the subscales), repeatability (r = 0.80–0.85), and inter-rater agreement (>90%).
