Dissociative Collusion: Reconnecting Clients with Histories of Trauma in Couple Therapy

This paper introduces the concept of “dissociative collusion” as a helpful theoretical and clinical tool for understanding and working with clients with histories of trauma in couple therapy. The paper describes ways to diagnose and treat dissociative collusion based on the integration of an object relations approach, a relational approach, and a narrative approach. Dissociative collusion, a unique version of the well‐documented “couple collusion,” describes relational unconscious dynamics where split‐off aspects of one or both partners are mutually dissociated in a complementary fashion that becomes a part of the shared unconscious and is reenacted in destructive ways. The dissociative collusion concept is especially relevant to couple therapists who work with clients with histories of trauma, who frequently use dissociation as a primary defense mechanism. We suggest that the challenge and goal for couple therapy with this population are to help them reconnect and better oscillate between dissociated self‐other configurations. A case of couple therapy of a wife who had been a victim of childhood sexual abuse and her husband who displayed frequent use of dissociative defenses is presented.     

Obsessive-compulsive disorder patients display enhanced latent inhibition on a visual search task

Latent inhibition (LI) is a phenomenon that reflects the ability to ignore irrelevant stimuli. LI is attenuated in some schizophrenic patient groups and in high schizotypal normal participants. One study has found enhanced LI in patients with obsessive-compulsive disorder (OCD [Swerdlow, N. R., Hartston, H. J., & Hartman, P. L., 1999. Enhanced visual latent inhibition in obsessive-compulsive disorder. Biological Psychiatry, 45, 482-488]). The present experiment replicated this finding using a within-subject visual search LI task, with OCD patients displaying more LI than healthy controls. The contrasting LI effects in schizophrenia and OCD are discussed in terms of how these groups differentially process relevant and irrelevant stimuli, and how that outcome affects subsequent behavior.     

The measurement of core affect: a Swedish self-report measure derived from the affect circumplex

Three studies were conducted with the aim of developing a new Swedish self-report measure of core affect (the Swedish Core Affect Scale or SCAS). In Study 1,122 participants rated their current mood on 24 unipolar adjective scales. A revised set of 12 bipolar adjective scales was evaluated in Study 2 employing 96 participants who rated their current mood before and after a mood-inducing naturally occurring event. A slightly revised set of adjective scales was used in Study 3, in which another 96 participants rated several induced moods. The results showed that the adjective scale ratings could be aggregated as reliable measures of the independent valence and activation dimensions proposed in the affect circumplex, and that the aggregated measures discriminated mood differences within and between individuals.     

Memory for emotionally neutral information in posttraumatic stress disorder: A meta-analytic investigation

Studies have come to conflicting conclusions about whether posttraumatic stress disorder (PTSD) is associated with poorer memory for emotionally neutral information. The authors report a meta-analysis of 27 studies that investigated verbal and/or visual memory in samples with PTSD and healthy controls. The results indicated that the association between PTSD and memory impairment appears to be robust, small to moderate in size, and stronger for verbal than for visual memory. Effect sizes did not vary according to whether recall was immediate or delayed. The association is found in both civilian and military samples and cannot be readily explained as being due to the use of nontraumatized healthy control groups or concurrent head injury. The findings are placed in the context of recent neurobiological and experimental cognitive research.     

Does It Make You Happy Feeling This Way? A Core Affect Account of Preference for Current Mood

Two experiments were conducted to investigate whether and how preference for current mood is related to the valence and activation dimensions of core affect. In Study 1, 100 undergraduates rated valence and activation of their naturally occurring current mood and preference for this mood. In Study 2, another 90 undergraduates performed the same ratings for various induced moods. The results showed as expected that preference for current mood is related to both valence and activation. Whereas the relation to valence is direct, the relation to activation is invertedly U-shaped with a maximum that increases with valence.
