Abstract
This paper conceptualizes security as involving all activities that are put in place to check adverse
forces that threaten the well-being of lives and property, or all activities involved ill ensuring that
citizens feel happy, and safe from danger and worry. It explored psychological trauma, pointing out
[he aetiological factors, the course and outcomes. Individual differences in people's reaction to
traumatic events were explained using cognitive theory, personality traits and availability or otherwise
of adequate social support, while the relationship between National security and psychological trauma
was established using the social learning theory, the motivational theory, the locus of control
orientation and attribution theory. The paper concludes that the current wave of crime and law breaking
in Nigeria can be drastically curtailed if traumatized people are healed and traumatogenic activities
are checked.
