The dark side of sexism in Argentina: Psychometric properties of the Short Dark Triad Personality measure and its relation with ambivalent sexism.

One of the main evaluation instruments of the dark side of personality has been the Short Dark Triad of Personality (SD3), that includes Machiavellianism, Narcissism and Psychopathy traits. Although other adaptations of this scale have been made in several countries, its psychometric properties have never been tested in Argentina. Different studies addressed that dark triad scores are related to different expressions of sexist prejudice.

Augmentation of light therapy in difficult-to-treat depressed patients: an open-label trial in both unipolar and bipolar patients.

Objectives: We investigated the clinical benefits of bright light therapy (BLT) as an adjunct treatment to ongoing psychopharmacotherapy, both in unipolar and bipolar difficult-to-treat depressed (DTD) outpatients.

Methods: In an open-label study, 31 depressed outpatients (16 unipolar and 15 bipolar) were included to undergo 3 weeks of BLT. Twenty-five completed the treatment and 5-week follow-up.

Clinical correlates of difficult-to-treat depression: Exploring an integrated day-care model of treatment.

Background And Aims: This study aimed to test the effectiveness of an individualized, integrated, day-care treatment programme for the acute phase of "difficult-to-treat depression" (DTD) in a sample of bipolar and unipolar subjects with a complex co-morbidity pattern.

Methods: A total of 291 patients meeting criteria for DTD were consecutively recruited. All participants underwent a 12-week day-care intervention including individual psychological support and group psycho-education.

Changes of dopamine transporter availability in depressed patients with and without anhedonia: a 123I-N-ω-fluoropropyl-carbomethoxy-3β- (4-Iodophenyl)tropane SPECT study.

Background/aims: Dopamine is an important neurotransmitter involved in the pathophysiology of depression and anhedonia. Dopamine transporters (DAT) may play a crucial role in the pathophysiology of dopaminergic transmission. We investigated the relationship between striatal DAT availability and depression, pointing out possible correlations with anhedonia and treatment outcomes.
