Previous research has found that cognitive biases in attention, interpretation, and memory play an important role in depression. However, there is little knowledge of the interplay between these biases in clinical depression. The present study was aimed to model different pathways of relation among attention, interpretation and autobiographical memory biases, and to examine their contribution to account for depression status outcomes. Cognitive biases were evaluated in a sample comprising 22 currently-depressed and 36 never-depressed individuals representing a broad range of depression severity levels. Cognitive biases were assessed by three separate tasks using different types of stimuli. Our main finding was a significant indirect effect model in which attention bias to negative faces was linked to greater negative memory bias via its association with negative interpretation bias. Within this model, the specific pathway between attention bias to negative faces and negative interpretation bias accounted both for significant variance in depression severity as well as for depression diagnostic status. These findings increase our understanding of the complex interplay between cognitive mechanisms involved in clinical depression and highlight hypothetical pathways relevant for future interventions.

Research over the last two decades on the role of positive emotions and cognitions in psychological functioning is leading to conceptual changes regarding the nature of mental disorders and the mechanisms underlying their onset and maintenance. This introduction to the latest breakthrough research on positive emotions and cognition offers a brief description of the emerging presence of positivity in current diagnostic systems like the DSM5 and Research Domain Criteria (RDoC). It also analyzes some select findings from the literature on experimental psychopathology supporting the relevance of examining positive aspects of functioning in clinical psychology. In addition, the study of positive aspects of psychological functioning adds a more conceptually complex understanding of psychopathology. The multiple perspectives encompassed in this special issue shed light on our understanding of the different roles that positive emotions and cognitions play in mediating normal and abnormal human functioning and their importance to improving research methods and interventions in psychopathology.

Traditionally, treatments for depression have been primarily focused on reducing patients' symptoms or deficits and less concerned with building positive resources. This study aims to compare the efficacy of a manualized protocol of empirically-validated positive psychology interventions (PPI) with a cognitive-behavioral therapy (CBT) protocol. This controlled clinical trial included 96 adult women with a DSM-IV diagnosis of major depression or dysthymia. Participants were blindly allocated to a 10-session PPI ( n = 47) or CBT ( n = 49) group therapy condition. Intention to treat analysis showed that both interventions were effective in reducing clinical symptoms and increasing well-being. There were no significant differences between groups in either main outcomes (i.e., severity of depressive symptoms and clinical diagnosis) or secondary outcomes (e.g., positive and negative affect, and satisfaction with life). Even within the most severely depressed participants, no differences between PPI and CBT emerged. If further clinical studies confirm these results, this would widen treatment choice for both patients and professionals. [ABSTRACT FROM AUTHOR]
