The results of a unique study from the University of Gothenburg, Sweden, show that personality has an impact on how likely people are to take their medication. This is the first major study of its kind to be published in the online open access journal PloS ONE. Check the end of this report for a link to download the original, full-text study.
The study was based on 749 people with chronic diseases who responded to a questionnaire on medication adherence behavior – or in other words, whether they take their medicine. Their personalities were also assessed using another questionnaire, the Five Factor Inventory (NEO-FFI), which comprises 60 statements with five different responses. The questionnaire was based on five personality traits: neuroticism, extroversion, openness to experiences, agreeableness, and conscientiousness.
