The study aimed to determine the extent of the impact of the Covid-19 coronavirus epidemic on the mental health of doctors in the Algerian desert environment, in the light of certain personality variables. The researchers used a descriptive approach, using an electronic questionnaire they had developed containing 42 statements distributed over 5 dimensions. After checking its psychometric properties, it was administered to a sample of 295 people covering most of the wilayas (provinces) of southern Algeria. After data processing and analysis, it was found that the Covid-19 coronavirus epidemic has a moderate impact on the mental health of doctors. There are also statistically significant differences between the individuals in the study sample in terms of the impact of the Covid-19 coronavirus epidemic on their mental health, which can be attributed to the gender variable in favour of women, as well as the location of the workplace (geographical area). However, there were no statistically significant differences in the variables of age, marital status, length of service, type of work and work institution. In light of these findings, the researchers proposed practical recommendations that could mitigate the impact of the Covid-19 corona virus epidemic on doctors' mental health and improve their ability to cope with crises.
