Abstract
Objective: Psychotherapy for depression emphasizes techniques that can help individuals regulate their moods. The present study investigated the affective impact and electrocortical correlates of cognitive restructuring, delivered as a 90-minute psychotherapeutic microintervention in a dysphoric sample. Method: Participants (N = 92) who reported either low or high levels of dysphoric symptoms were randomly assigned to the restructuring microintervention, a control intervention or a no-intervention condition. We obtained recordings of event-related potentials (ERPs) as well as mood self-ratings during an experimental session immediately after the psychotherapeutic microintervention and the control intervention in which a set of negatively valenced pictures (IAPS) was presented with different instructions. Results: Whereas the restructuring intervention group and the control intervention group reported both increases in positive and decreases in negative affect from pre- to post-intervention, the three groups differed significantly on ERP measures. Conclusions: Findings provide support for current models of mechanisms of action in cognitive therapies. © 2013 © 2013 Society for Psychotherapy Research.

Professor Strauman's research focuses on the psychological and neurobiological processes that enable self-regulation, conceptualized in terms of a cognitive/motivational perspective, as well as the relation between self-regulation and affect. Particular areas of emphasis include: (1) conceptualizing self-regulation in terms of brain/behavior motivational systems; (2) the role of self-regulatory cognitive processes in vulnerability to depression and other disorders; (3) the impact of treatments for depression, such as psychotherapy and medication, on self-regulatory function and dysfunction in depression; (4) how normative and non-normative socialization patterns influence the development of self-regulatory systems; (5) the contributory roles of self-regulation, affect, and psychopathology in determining immunologically-mediated susceptibility to illness; (6) development of novel multi-component treatments for depression targeting self-regulatory dysfunction; (7) utilization of brain imaging techniques to test hypotheses concerning self-regulation, including the nature and function of hypothetical regulatory systems and characterizing the breakdowns in self-regulation that lead to and accompany depression.
