Scientists in Brazil have linked resistance to Covid-19 safety measures, such as wearing a mask, with traits of Anti-Social Personality Disorder.
Their study was the first of its kind in Latin America and surveyed over 1,500 people aged 18-73.
Using a questionnaire, the scientists sought to identify the participants’ affective resonance - their impulse to act on feelings stirred by another person - and asked a series of personality questions about how well certain statements represented their behaviour.
The survey also asked about compliance with Covid-19 containment measures over time, such as mask wearing.
When profiles were analysed, two were identified: an antisocial pattern profile and an empathy pattern profile.
The antisocial profile was linked to higher scores in “callousness, deceitfulness, hostility, impulsivity, irresponsibility, manipulativeness, and risk-taking” which are typical of Antisocial Personality Disorder, as well as lower scores in affective resonance.
The empathy pattern profile showed higher scores in affective resonance and lower scores in the traits associated with Antisocial Personality Disorder (ASPD).
The team who conducted the study said they hoped the findings would help to persuade health officials to do more to educate people and influence their policies.
"Through screenings that demonstrate an elevation in these [ASPD] traits, interventions can be carried out aiming at greater awareness and consequent compliance with containment measures”, the team explained.
While worldwide protests have taken place surrounding mask wearing, their effectiveness continues to be proven in a growing number of studies.
