Since the beginning of the COVID-19 pandemic in Spain, members of the State Security
Forces and the Armed Forces have been mobilized to guarantee the security and mobility of the
population and to support health institutions by providing personnel for care, creating field hospitals,
transferring the sick and the dead, etc. The objective of this study was to determine the levels of
burnout in these professionals using the Maslach Burnout Inventory (MBI) scale, both in its different
subscales and its total value. The study was developed using a quantitative methodology through a
simple random sample (n = 2182). An ad hoc questionnaire was administered including variables
related to: (a) socio-demographic issues, (b) subjective perceptions about their working conditions
and the need for psychological and psychiatric treatment, and (c) the Death Anxiety Scale developed
by Collett–Lester, and the MBI. The results show high levels of burnout (28.5%) in all its subscales:
emotional exhaustion (53.8%), depersonalization (58.0%), and lack of personal development (46.3%).
The logistic regression verifies a series of predictive variables that coincide in each of the subscales.
These data indicate the need to implement prevention and treatment measures for workers so that
their, stress, and anxiety to which they are subjected during their professional activity does not
become a norm that can have negative repercussions for them, especially given the risk of new
pandemic waves.
