A prospective investigation of the impact of attachment style on stress generation among clinically depressed individuals

The present study sought to determine if attachment style contributed to the generation of stressful life events among clinically depressed individuals during the course of treatment. Participants (N=68) were interviewed about life stressors experienced during a 3-month treatment protocol using a contextual approach (Life Events and Difficulties Schedule; [Brown, G. W., & Harris, T. O. (1978). Social origins of depression: A study of psychiatric disorder in women. New York: Free Press]). Results suggested interactive effects between severity of depression and attachment style on stress associated with future sociotropic and dependent life events. Mildly depressed individuals who reported a dismissing attachment style (higher levels of avoidant attachment and lower levels of anxious attachment) or preoccupied style (lower levels of avoidant attachment and higher levels of anxious attachment) experienced higher levels of stress associated with sociotropic events. Likewise, a dismissing attachment style predicted stress associated with dependent events among mildly depressed individuals. These effects were not present among our more severely depressed participants.     

Social anxiety and posttraumatic stress in combat veterans: relations to well-being and character strengths

There are few studies examining the relationship between psychopathology and positive experiences and traits. Although initial studies suggest persons with posttraumatic stress disorder (PTSD) are at increased risk for excessive social anxiety, there have been no studies to date evaluating how these conditions might interact to affect positive experiences and traits. Using self-report scales, informant ratings, and experience-sampling methodologies, we examined the association of social anxiety with well-being and character strengths in veterans with and without PTSD. Controlling for PTSD and trait negative affect, social anxiety was negatively related to global ratings of well-being and character strengths. Social anxiety also accounted for incremental variance in day-to-day well-being (i.e., daily affect balance, percentage of pleasant days, positive social activity, self-esteem, gratitude) over a 14-day assessment period. Although veterans with PTSD reported lower levels of global and daily well-being and character strengths than veterans without PTSD, a diagnosis of PTSD failed to exhibit unique relationships with these constructs. Building on a growing body of work, these data suggest that social anxiety is uniquely associated with disturbances in positive experiences, events, and traits. Our findings support the value of directly addressing social anxiety in the study and treatment of PTSD.     

Anhedonia and emotional numbing in combat veterans with PTSD

We explored relationships between anhedonia and posttraumatic stress disorder (PTSD) symptom clusters, including their role in predicting psychiatric comorbidity. Our measure of anhedonia was derived from an examination of the latent structure of the Beck Depression Inventory. We found evidence for a two-factor solution, leading to anhedonia and undifferentiated, global depressive symptoms scales. In primary analyses, anhedonia had a unique positive relationship with PTSD's emotional numbing symptoms and minimal relationships with other PTSD symptoms. Upon examining the incremental validity of appetitive functioning (i.e., anhedonia, emotional numbing) over and above aversive functioning (i.e., re-experiencing, avoidance, and hyper-arousal PTSD symptoms) variables, greater emotional numbing increased the likelihood of being diagnosed with a major depressive disorder, and greater anhedonia increased the likelihood of being diagnosed with additional anxiety disorders and to a lesser extent, psychotic disorders. Results were consistent with research on the distinction of appetitive and aversive functioning, providing insight into the nature of PTSD.     

Expanding the topography of social anxiety. An experience-sampling assessment of positive emotions, positive events, and emotion suppression

The relation between social anxiety and hedonic activity remains poorly understood. From a self-regulatory perspective, we hypothesized that socially anxious individuals experience diminished positive experiences and events on days when they are unable to manage socially anxious feelings adequately. In this 21-day experience-sampling study, we constructed daily measures of social anxiety and emotion regulation. Greater dispositional social anxiety was associated with less positive affect and fewer positive events in everyday life. Among individuals defined as socially anxious from their scores on a global self-report measure of social anxiety, the number of positive events was lowest on days when they both were more socially anxious and tended to suppress emotions and highest on days when they were less socially anxious and more accepting of emotional experiences. Irrespective of dispositional social anxiety, participants reported the most intense positive emotions on the days when they were both least socially anxious and most accepting of emotional experiences. Possible clinical implications are discussed.     

Failure to capitalize on sharing good news with romantic partners: Exploring positivity deficits of socially anxious people with self-reports,partner-reports,and behavioral observations

Extending prior work on social anxiety and positivity deficits, we examined whether individual differences in social anxiety alter the ability to share and respond to the good news of romantic partners (i.e., capitalization support) and how this influences romantic relationship satisfaction and commitment. In this study of 174 heterosexual couples (average age of 21.5 with 58.3% identifying as Caucasian), greater social anxiety was associated with the provision and receipt of less supportive responses to shared positive events as measured by trait questionnaires, partner reports, and behavioral observations in the laboratory. In longitudinal analyses, individuals in romantic relationships with socially anxious partners who experienced inadequate capitalization support were more likely to terminate their relationship and report a decline in relationship quality six months later. As evidence of construct specificity, social anxiety effects were independent of depressive symptoms. Taken together, social anxiety influenced a person's ability to receive and provide support for shared positive events; these deficits had adverse romantic consequences. Researchers and clinicians may better understand social anxiety by exploring a wider range of interpersonal contexts and positive constructs. The addition of capitalization support to the social anxiety literature offers new insights into interpersonal approaches and treatments.     

Examination of the factor structure and concurrent validity of the Langer Mindfulness/Mindlessness Scale

Langer's theory of mindfulness proposes that a mindful person seeks out and produces novelty, is attentive to context, and is flexible in thought and behavior. In three independent studies, the factor structure of the Langer Mindfulness/Mindlessness Scale was examined. Confirmatory factor analysis failed to replicate the four-factor model and a subsequent exploratory factor analysis revealed the presence of a two-factor (mindfulness and mindlessness) solution. Study 2 demonstrated that the two factors assessed discrete constructs and were not merely products of acquiescence. Support was also found for a nine-item, one-factor model comprised solely of mindfulness items. On comparing models, Study 3 suggested the superiority of the one-factor mindfulness model. Finally, a preliminary investigation of the concurrent validity of the revised nine-item Langer Mindfulness/Mindlessness Scale is presented. The current article offers researchers a revised version of a mindfulness measure derived from a cognitive perspective.
