However, this assumption has been based predominantly on correlational findings. With the advent of attentional bias modification techniques , it became possible to modify attentional bias experimentally. The purpose of this study was to ascertain whether negative attentional biases are trainable and causally linked to changes in important characteristics of depression, namely self-esteem. Participants completed negative attentional training and a stress induction task. Consistent with the diathesis-stress model, a combination of negative attentional biases and stress resulted in changes in self-esteem, which was used as an indicator of depression. The effects on self-esteem were specific to the type of stimuli used. These findings have important implications for our understanding of self-esteem, cognitive models of depression, and for the future of cognitive bias modification research in self-esteem and depression.

In this study, in a sample of 105 individuals with PTSD, clinical correlates of alexithymia included reexperiencing, hyperarousal, numbing, dissociative symptoms, and retrospectively reported experiences of childhood emotional neglect. In a subsample of 26 individuals with PTSD related to a motor vehicle accident, functional neural responses to trauma-script imagery were associated with severity of alexithymia, including increased right posterior-insula and ventral posterior-cingulate activation and decreased bilateral ventral anterior-cingulate, ventromedial prefrontal, anterior-insula, and right inferior frontal cortex activation. Clinical and theoretical implications and future research directions are discussed.

It remains unclear whether memory impairments exist for information presented in therapy among anxiety patients who are concomitantly taking BZs. This naturalistic study compared 16 panic disorder patients who were daily BZ users with 16 age-and education-matched, nonmedicated panic disorder patients. An incidental memory task assessed memory for psychoeducation material on the origins and management of somatic anxiety symptoms presented during group cognitive behavioral therapy (CBT). BZ users showed significantly poorer memory performance than controls although there were no group differences in anxiety symptoms, rates of psychiatric comorbidity, or sedation. Among BZ users, a higher number of minutes away from post peak drug-blood concentration when encoding began, was also associated with better incidental memory performance. Although causation cannot be inferred from this naturalistic study, the memory impairments observed among BZ users may contribute to the poorer efficacy of CBT previously documented in panic disorder patients receiving adjunctive BZs.

The HDI exhibited high internal consistency and support for its construct validity was demonstrated by the HDI's patterns of correlations with other measures of depression, anxiety, and depression-relevant cognition. Factor analyses of the full (23-item) and 17-item versions of the HDI each yielded 4 factors, which accounted for 49% and 53% of the variance in participants' responses, respectively. The utility of the HDI's use of multiple-weighted subitems was also assessed by comparing a less complicated scoring system to the standard scoring format. The standard HDI added significantly to the prediction of criterion indexes after controlling for the variance accounted for by the "simplified" HDI. Moreover, the operating characteristics of the standard HDI outperformed the simplified HDI in the prediction of the Beck Depression Inventory-II (Beck, Steer, & Brown, 1996) classification. The results provide strong support for the HDI as a reliable and valid instrument for the assessment of depressive severity

This article outlines some key interpersonal risk factors for depression, including anxious attachment, sociotropy, excessive reassurance seeking, interpersonal stress generation, reduced social support, social skills deficits, and social avoidance. Recommendations are made for how cognitive-behavioural therapy may be adapted to address such factors. Specifically, suggestions are offered for how cognitive and behavioural interventions, such as cognitive restructuring, behavioural activation, behavioural experiments, and skills training, may be used with depressed clients to promote positive relationships and reduce maladaptive interpersonal behaviours.
