[Psychometric properties of the Barratt Impulsiveness Scale in a sample of the city of Buenos Aires].

The Barratt Impulsiveness Scale was designed to assess the impulsivity construct in three dimensions: attentional, motor and unplanned. The scale has been applied to patients with different diagnoses in which the impulsivity symptoms are characteristic. In Argentina there aren't studies that evaluate the psychometrics properties of the scale in clinical population.

Dysfunctional cognitions and their emotional, behavioral, and functional correlates in adults with attention deficit hyperactivity disorder (ADHD): is the cognitive-behavioral model valid?

Objective: To investigate the presence of dysfunctional cognitions in adults with ADHD and to determine whether these cognitions are associated with emotional symptoms, maladaptive coping, and functional impairment, as predicted by the cognitive-behavioral model.

Method: A total of 35 adult participants with ADHD, 20 nonclinical controls, and 20 non-ADHD clinical controls were assessed with measures of ADHD symptoms, dysfunctional cognitions, depression and anxiety symptoms, coping strategies, and quality of life.

Results: ADHD group showed elevated scores of dysfunctional cognitions relative to nonclinical control group and comparable with clinical control group.
