 A key concept in Antonovsky's theory concerns how specific personal dispositions serve to make individuals more resilient to the stressors they encounter in daily life.Antonovsky identified these characteristics, which he claimed helped a person better cope (and remain healthy) by providing that person a "sense of coherence" about life and its challenges; Helen Antonovski (his wife) developed a scale ("Orientation to life questionnaire") in 1987 to measure it.Recent research in psychoneuroimmunology has supported the relationship between emotions and health contained in Antonovsky's theory.
