Each of us, in our daily lives, suffers from the influence of a series of variables and responds to such an influence in a certain way. The result of this wide set of factors yields to health and wellbeing or to pathology and suffering. The clinical psychologist is interested by human behavior: they research, assess, and treat human behavior. They try to unravel why and how such wellbeing or such suffering takes place. The latter is the core aspect of the clinical psychologists concern: they consider human suffering with a clinical attitude and wish to do something about it. Their main and basic goal is to help.

Along its more than 100 years of existence, Clinical Psychology has progressed considerably in the understanding and explanation of many of the factors that give raise to both, healthy human behavior and pathological human behavior. These advances have allowed the design of different tools that make feasible accurate diagnosis, reliable assessments, and effective treatment protocols for many psychological problems. Next, we present examples of several problems to which appropriate assessment and treatment protocols have been structured that the therapists at PREVI's Psychology Clinical Center use in their daily clinical practice.
