### Measures
To measure the conformity and lying tendency, there is a fourth subscale integrated into the inventory (L). The Hungarian version of the questionnaire contains 58 questions and the students' task was to decide whether the item applied to them or not. The psychometric properties of the test are acceptable based on a meta-analysis; [PERSON]'s \(\alpha\) (alpha) values (a measure of internal consistency) are between 0.58 and 0.85 [52]. The third survey was the Emotional Intelligence Inventory, developed by [PERSON] [53; 54]. The test contains 121 items and asks students for a self-report on how much the items describe them, using a 5-point Likert-scale. Emotional intelligence is divided into 5 scales with a different number of subscales: intrapersonal scale, which assesses the self-awareness and self-expression (subscales are self-regard, emotional self-awareness, assertiveness, independence, and self-actualization); interpersonal scale, which measures social awareness and interpersonal relationship (subscales are empathy, social responsibility, and interpersonal relationship); stress management scale, which assesses emotional management and regulation (subscales are stress tolerance and impulse control); adaptability scale, which measures change management (subscales are reality-testing, flexibility, and problem-solving), and general mood scale, which measures competencies of self-motivation (subscales are optimism and happiness) [55; 56] (p. 21). This is a widely used emotional intelligence test with acceptable psychometric properties: high Cronbach \(\alpha\)-s on each scale and subscale (0.67-0.79) and good test-retest reliability, even in a multicultural context [53; 55]. Next, we measured the positive source competencies with the help of PERMA Profiler, this is the first holistic measurement tool of well-being [42]. We used the 23-item questionnaire; the refined model has acceptable psychometric attributes with \(\alpha\)-s between 0.60 and 0.94 on each scale, except 2 scales (happiness and loneliness), which contain only 1 item [42]. For PERMA happiness and loneliness, there are no \(\alpha\)-s because these factors contain only one question, so the calculation of the value is unnecessary. The final structure has seven subscales, five from the original PERMA structure: positive emotion, engagement, positive relationship, meaning or purpose in life, accomplishment, and two new factors of the refined model: negative emotion, physical health. The authors suggest using these factors separately and not as a general PERMA score because it seems to be an umbrella term [42]. We also used the Grit-Short (Grit-S) questionnaire, which is dedicated to measuring perseverance (at a trait-level) and the passion for long-term goals. It contains 8 items, and students indicate how much the items describe them using a Likert-scale. This short questionnaire has strong psychometric characteristics (\(\alpha\)-s = 0.82 and 0.84) [57]. As behavioral factors, we measured stress management and coping skills using two questionnaires with acceptable psychometric characteristics developed by [PERSON] [58; 59]. The first tool was the coping preferences test that contains 80 items with a 4-point Likert-scale in which students decide how often they use the offered answer in a stressful situation. The test gives a profile of preferences on 8 coping mechanisms: problem-focused strategies (e.g., problem-focused reaction), support-finding strategies (e.g., support seeking), and emotion-focused strategies (e.g., impulse control, emotion-focused actions, acting out, self-punishment, acquiescence, and attention diversion). As another aspect of coping, the measurement of the psychological immune system focused on mental and psychological aspect of stress management. The test contains 80 items with a 4-points Likert-scale.
