Objective: Research on predictors of treatment outcome in depression has largely derived from randomized clinical trials involving strict standardization treatments, stringent patient exclusion criteria and careful selection supervision study clinicians.The extent to which findings such studies generalize naturalistic psychiatric settings is unclear.This sought predict outcomes for patients seeking within an intensive hospital setting, while comparing the performance a range machine learning...

Positive urgency, the tendency to respond impulsively positive affective states, has been linked many psychopathologies, but little is known about mechanisms underpinning this form of impulsivity. We examined whether Urgency Measure (PUM) related higher scores on performance-based measures impulsivity and cognitive control that were administered after a mood induction. Undergraduates (n = 112) completed self-report PUM, several inductions, behavioral control. PUM significantly poor...

A growing empirical literature indicates that emotion-related impulsivity (compared to is unrelated emotion) particularly relevant for understanding a broad range of psychopathologies. Recent work, however, has differentiated two forms impulsivity: factor termed Pervasive Influence Feelings captures tendencies emotions (mostly negative emotions) quickly shape thoughts, and Trigger Action positive reflexively behaviour speech. This study used path modelling consider links from...

Abstract Prior research suggests that a traitlike tendency to experience impulsivity during states of high emotion is robustly associated with many forms psychopathology. Several studies tie emotion‐related response inhibition deficits, but these have not focused on the role or arousal within subjects. The present study tested whether arousal, measured by pupil dilation, amplifies deficits in for those impulsivity. Participants ( N = 85) completed measure impulsivity, underwent positive mood...

Despite the centrality of emotion disturbance in neurobiological models bipolar disorder, behavioral literature has not yet clearly identified most central aspects disorder. Toward this aim, we gathered a battery emotion-related measures 67 persons diagnosed with I disorder as assessed SCID and well-matched control group 58 without history mood disorders. Those were interviewed monthly until they achieved remission, then tested on measures. A subset 36 participants completed symptom severity...

Research has implicated motivation and goal regulation in susceptibility to mood disorders. We studied for the first time key facets of concurrently relation affective symptoms. The cross-national sample comprised 510 university students from United States (n = 279) Kingdom 231). Participants completed self-report measures motivation, conditional setting, urgency, depression, anxiety, mania risk. Structural Equation Modeling results found that behavioral activation system scores correlated...
