Interactive Team Cognition

Cognition in work teams has been predominantly understood and explained in terms of shared cognition with a focus on the similarity of static knowledge structures across individual team members. Inspired by the current zeitgeist in cognitive science, as well as by empirical data and pragmatic concerns, we offer an alternative theory of team cognition. Interactive Team Cognition (ITC) theory posits that (1) team cognition is an activity, not a property or a product; (2) team cognition should be measured and studied at the team level; and (3) team cognition is inextricably tied to context. There are implications of ITC for theory building, modeling, measurement, and applications that make teams more effective performers.     

Mechanisms of change in cognitive behavioral therapy for panic disorder: The unique effects of self-efficacy and anxiety sensitivity

The present study examined temporal dependencies of change of panic symptoms and two promising mechanisms of change (self-efficacy and anxiety sensitivity) during an 11-session course of cognitive-behavior therapy (CBT) for Panic Disorder (PD). 361 individuals with a principal diagnosis of PD completed measures of self-efficacy, anxiety sensitivity, and PD symptoms at each session during treatment. Effect size analyses indicated that the greatest changes in anxiety sensitivity occurred early in treatment, whereas the greatest changes in self-efficacy occurred later in treatment. Results of parallel process latent growth curve models indicated that changes in self-efficacy and anxiety sensitivity across treatment uniquely predicted changes in PD symptoms. Bivariate and multivariate latent difference score models indicated, as expected, that changes in anxiety sensitivity and self-efficacy temporally preceded changes in panic symptoms, and that intraindividual changes in anxiety sensitivity and self-efficacy independently predicted subsequent intraindividual changes in panic symptoms. These results provide strong evidence that changes in self-efficacy and anxiety sensitivity during CBT influence subsequent changes in panic symptoms, and that self-efficacy and anxiety sensitivity may therefore be two distinct mechanisms of change of CBT for PD that have their greatest impact at different stages of treatment.     

The Interactive Contributions of Perceived Control and Anxiety Sensitivity in Panic Disorder: A Triple Vulnerabilities Perspective

Within the triple vulnerabilities model of anxiety disorders, a genetic contribution to the development of anxiety and negative affect (i.e., generalized biological vulnerability), a diminished sense of perceived control over aversive events and emotional experiences (i.e., generalized psychological vulnerability), and elevated levels of anxiety sensitivity (i.e., specific psychological vulnerability) are posited to increase the risk of developing and maintaining panic disorder (Barlow American Psychologist 55(11):1247–1263, 2000). The purpose of the present study was to investigate the direct and interactive effects of perceived control and anxiety sensitivity on panic disorder symptom severity. Structural equation models (SEM) were conducted in data derived from a sample of 379 adults with panic disorder participating in a multi-site randomized controlled trial. Findings indicated that both perceived control and anxiety sensitivity uniquely predicted panic disorder symptoms. A moderation model examining the interactive effects of perceived control and anxiety sensitivity on panic symptoms indicated that the effect of anxiety sensitivity on panic symptoms increased with greater deficits in perceived control. The present findings suggest that deficits in perceived control and elevated levels of anxiety sensitivity exert unique and shared effects on panic disorder symptoms, thereby illustrating the relationship between putative vulnerability factors and panic disorder symptoms as predicted by the triple vulnerabilities model.     

Cognitive-Behavior Therapy (CBT) for Panic Disorder: Relationship of Anxiety and Depression Comorbidity with Treatment Outcome

Research evaluating the relationship of comorbidity to treatment outcome for panic disorder has produced mixed results. The current study examined the relationship of comorbid depression and anxiety to treatment outcome in a large-scale, multi-site clinical trial for cognitive-behavior therapy (CBT) for panic disorder. Comorbidity was associated with more severe panic disorder symptoms, although comorbid diagnoses were not associated with treatment response. Comorbid generalized anxiety disorder (GAD) and major depressive disorder (MDD) were not associated with differential improvement on a measure of panic disorder severity, although only rates of comorbid GAD were significantly lower at posttreatment. Treatment responders showed greater reductions on measures of anxiety and depressive symptoms. These data suggest that comorbid anxiety and depression are not an impediment to treatment response, and successful treatment of panic disorder is associated with reductions of comorbid anxiety and depressive symptoms. Implications for treatment specificity and conceptual understandings of comorbidity are discussed.     

Group Cognitive-Behavioral Therapy for Insomnia in a VA Mental Health Clinic

Effective cognitive-behavioral therapies for insomnia have been developed over the past 2 decades, but they have not been systematically evaluated in some clinical settings. While insomnia is common among veterans with mental health problems, the availability of effective treatments is limited. We report on the group application of a cognitive-behavioral therapy for chronic insomnia in a veteran population with significant comorbidity for both psychiatric problems and chronic medical conditions. Outcome measures were obtained for both sleep (via sleep diaries) and daytime functioning. Substantial posttreatment improvements were evident for measures of sleep consolidation, total sleep time, depression, anxiety, and fatigue. The unique suitability of the group therapy approach with this population is discussed. Controlled evaluations of the group cognitive-behavioral treatment for comorbid insomnia in this and other ambulatory settings are warranted.     

Peer relationships and academic achievement as interacting predictors of depressive symptoms during middle childhood

This article reports a longitudinal investigation that examines academic and social difficulties as predictors of depressive symptoms during middle childhood. Participants were 199 elementary school children (M=9.1 years) who were followed for 2 consecutive school years. In both years of the project, children completed a questionnaire assessing depressive symptoms and a peer nomination inventory assessing friendships and social standing. Grade point averages (GPAs) were obtained from a review of school records. Low GPAs were predictive of depressive symptoms, but this effect did not hold for children who had numerous friends. Similarly, children who had relatively few friends tended to experience depressive symptoms. However, the effect was attenuated for children with high GPAs. Taken together, the findings suggest that competencies in 1 domain can moderate the risks associated with difficulties in the other domain.     

Violent Victimization in the Community and Children’s Subsequent Peer Rejection: The Mediating Role of Emotion Dysregulation

This paper describes a short-term longitudinal study of the relation between violent victimization in the community and peer rejection among 199 children (mean age = 9.02 years) attending two urban Los Angeles area elementary schools. We used a multi-informant approach to assess victimization by community violence, peer group victimization, peer rejection, and impairments in emotion regulation. These data were collected annually for two consecutive school years. Violent victimization in the community predicted later peer rejection after accounting for the effects of initial levels of peer rejection. Analyses indicated that this relation was mediated by deficient emotion regulation skills. In addition, we found evidence that victimization by community violence and peer rejection are reciprocally related over time. The developmental implications of these findings are discussed.     

Construct Validity of the Acquired Capability for Suicide Scale: Factor Structure,Convergent and Discriminant Validity

The Acquired Capability for Suicide Scale (ACSS) assesses one of three main constructs in the Interpersonal Theory of Suicide but evidence of its validity is limited. In two studies (Ns = 287 and 738) validity of the full 20-item ACSS and its shorter versions (ACSS-5, ACSS-8, ACSS-FAD) were examined in terms of factor structure and relation to indices of self-reported suicidal behaviour and self-harm. Confirmatory factor analysis (CFA) failed to show good fit for one-, two-, or three-factor models of the ACSS in its various versions. Exploratory factor analysis of the 20-item scale in the first study pointed instead to a five-factor structure and this was supported using CFA in the second study. In both studies all scale versions showed moderate negative correlations to fear of death and dying, indicating scale validity for the purpose of assessing fearlessness about death. In the second study, a model in which the five factors were indicators of a latent variable of Capability was found to predict a latent variable of Suicidality as indicated by suicidal behaviours, but the prediction was substantially enhanced by the addition of Item 20 to the model. This single item was also found in the first study to better predict suicidal and self-harming behaviour than the full ACSS or any of its short versions.
