The study aims at comparing three groups: 101 emergency health workers, 260 volunteers, and 827 subjects belonging to a normative sample not involved in prolonged helping activities. Participants filled out self-report questionnaires aimed to measure personality traits, values, and motives. Results showed interesting differences: health workers and volunteers reported higher friendliness and emotional stability than the normative sample; they also gave higher priority to self-transcendence values. Health workers reported high conscientiousness and openness to novelty and new experiences, whereas volunteers gave lower priority to personal success and power than the other two groups.
