We will present the results of an on-going research, carried out in the South of Portugal, with the main purpose of investigate and analyse the mediators and modulators effects of some psychosocial factors and variables theoretically and empirically related to suicidal behaviour in adult attempters.

Sample: 60 adults, males and females, recurring to the emergency room of a general hospital as a consequence of a recent suicidal attempt.

A multimodal assessment matrix is being used to evaluate depression, suicidal ideation and intention, and individual, social, and environmental factors commonly related to the onset of major depression, namely hopelessness and pessimism, cognitive processing, interpersonal relations, and life events.

We expect to find a mediator effect, of cognitive and interpersonal processes, on the relationship between hopelessness and pessimism with depression and suicidal intentions.
