[Development and validation of a psychometric instrument for the assessment of depression in the elderly].

Depression is one of the main the psychological disorders in the gerontological population. However, in many cases the depressive alterations can go unnoticed or masked by the elderly s somatic complaints; or even the depressive symptoms can be ascribe to the own aging process. Moreover, it has to be added that old patients tend not to request help to specialised mental health centres. Therefore, the correct diagnosis of the depressed elderly's emotional problems becomes into a question of extraordinary importance. In this work is presented a new specific instrument for the evaluation of depression in the elderly people which has, among other characteristics, the advantage of requiring a little time to its application and a low knowledge on psychopathology. The initial results show an extraordinary sensitivity and specificity regarding to DSM-IV-TR criteria. Nevertheless, further studies with a higher number of clinical populations are necessary to confirm and enlarge these preliminary results.
