Emergencies, such as after an accident or disaster occurs, this can result in significant damage or loss of life.

Used to represent a genre of film, natural disasters or accidents should be used as a main driver of plot and setting.

We study or discussion of the implications of what this phenomenon is very well aware. So we 'Disaster' hypothesis of so-called negative psychological consequences. It is the concept of the concept of a disaster, seem simply the task is much more complex at first glance seem too much. Is a more complex task to identify disaster mental health effects. Behavior is self explanatory. Disaster literature, most of the disaster reached consensus on the definition of the basic concepts or their derivatives. In addition many letters of positive mental health and relationship between opportunities for location-based security offers. The basic theme of this paper is to understand that we are. This prevented us from lack of consensus is defined, and drew attention to the effective and important conclusions on the relationship between psyche and research capacities of disaster. Related models, key questions, and a reasonable assumptions between enough on the clarification of key concepts of the concept of disaster, indicating if higher progress, United States the work in this field of research is rare.

:

1. A sudden event, such as an accident or a natural catastrophe, that causes great damage or loss of life.
2. Denoting a genre of films that use natural or accidental catastrophe as the mainspring of plot and setting.

Disaster is a global issue.

Whenever we want to research or discuss the consequences of any phenomenon, we need to have a clear idea of what that phenomenon is. So it is when we hypothesize that what we call "disaster" has negative consequences for mental health. While it may seem easy to conceptualize what constitutes a disaster, the task is far more complicated than appears at first glance. Even more complicated is the task of identifying the mental health effects of disasters. The phenomena are not self-evident. The disaster literature yields little consensus on the definition of the basic concept of disaster or any of its derivatives. Nor does the literature provide much of an empirically based position on any possible relationship between disaster occasions and mental health. An underlying theme of this paper is that we will never clearly understand the effects disasters may have on mental health unless we clarify what we want to consider as a disaster, including the most important dimensions of disaster. The lack of consensus on any such definition has impeded research and hindered our ability to draw valid and significant conclusions about the relationship between disasters and mental health. While enough work has been done to suggest relevant models, significant questions, and reasonable hypotheses, there is likely to be little progress in this research area unless we move toward conceptual clarification of the key concept involved, that is, disaster.
