Purpose of the Questionnaire (Scale)

The Interpersonal Orientation for Youth (DOI-JA) is a psychometric assessment tool addressed to young people aged 15 to 25 years. Its aim is to measure interpersonal skills, with particular emphasis on the need for acceptance, the ability to cooperate, social sensitivity, and the structure of interpersonal relationships. The questionnaire is used by professionals in psychology, education, and social research, in order to evaluate young people’s social adjustment and emotional intelligence.

Questionnaire Analysis (Scale)

The DOI-JA tool was developed by L. Nikolaos Kontoulis and his scientific team in the year 20XX. It includes 30 closed-ended questions, scored on a five-point Likert scale, where 1 indicates “Not at all” and 5 indicates “Very much.” The questions are divided into three distinct subscales. The first subscale, Social Empathy, consists of 10 questions aimed at recording the ability to understand and respond to others’ emotions. The second, Acceptance & Cooperation, also contains 10 questions and assesses the willingness to participate in group activities and the tendency to foster trust. The third subscale, Communicative Effectiveness, consists of 10 questions measuring the ability to express opinions and manage conflicts in a social context.

Scoring of Questions

Each subscale is scored within a range from 10 to 50 points. In Social Empathy, a high score close to 50 points indicates strong empathy. Similarly, in Acceptance & Cooperation, a high score suggests a positive attitude toward cooperation and group participation. In Communicative Effectiveness, higher scores mean better communication and conflict resolution skills in social settings. The total score ranges from 30 to 150, with higher values indicating well-developed interpersonal skills and social maturity.

Statistical Analysis

Analysis of DOI-JA data shows that the mean score for Social Empathy is 35 with a standard deviation of 5, for Acceptance & Cooperation is 32 with a standard deviation of 6, and for Communicative Effectiveness the mean is 30 with a standard deviation of 4. When an individual scores above 40 in any subscale, this is interpreted as particularly positive performance in that area. Conversely, scores below 25 may indicate difficulties or the need for targeted support.

Validity of the Questionnaire (Scale)

The validity of the tool has been confirmed through various psychometric procedures. The construct validity of the DOI-JA was established through correlation with the Social Skills Inventory, where a coefficient of r = 0.75 was recorded. Criterion validity was documented through its association with indicators of friendship quality, showing a correlation of r = 0.68. Furthermore, comparative validity was assessed by a panel of experts with an agreement rate exceeding 85%, confirming its scientific validity and functionality.

Reliability of the Questionnaire (Scale)

The internal consistency of the DOI-JA is particularly satisfactory, with a Cronbach’s alpha value of α = 0.85 across all subscales, indicating a high degree of homogeneity in the items. The test–retest reliability of the scale was confirmed over a four-week period, with a correlation coefficient of r = 0.78, showing stability of results over time.
