Internetchatgruppen in Psychotherapie und Psychosomatik

Zusammenfassung  In Zusammenarbeit mit der Techniker Krankenkasse (TK) und der Panorama-Fachklinik für Psychosomatik, Psychotherapeutische Medizin und Naturheilverfahren Scheidegg/Allgäu hat die Forschungsstelle für Psychotherapie das Projekt Internetbrücke initiiert. Die Patienten erhielten im Anschluss an ihre stationäre Behandlung das Angebot, für 12–15 Wochen an einer Gruppe teilzunehmen, die sich in einem speziell eingerichteten Chatraum wöchentlich traf. Das Projekt hatte die Ziele: (a) eine geeignete Internetumgebung für eine vertrauliche Kommunikation aufzubauen und deren Praktikabilität zu testen sowie (b) die Akzeptanz durch die Patienten und die Wirksamkeit zu evaluieren. Zur Evaluation wurde eine prospektive kontrollierte Studie durchgeführt. Chatteilnehmer (n=114) wurden mit einer gematchten Vergleichsgruppe (n=114) hinsichtlich ihres Gesundheitszustands ein halbes Jahr nach der Klinikentlassung verglichen. Die Technik erwies sich als robust und nutzerfreundlich. Das Angebot wurde sehr positiv von den Patienten aufgenommen; dies drückte sich u. a. in der niedrigen Abbruchrate (9,4%) und der hohen Akzeptanz (83,7% der Chatteilnehmer hielten eine Internetbrücke für sinnvoll) aus. Die Chatteilnehmer konnten die während der stationären Behandlung erreichten positiven Entwicklungen – gemessen mit dem globalen Kriterium der Stuttgart-Heidelberger Qualitätssicherung – besser erhalten als die Vergleichsgruppe (p<0,05). Es zeigten sich Vorteile für die Chatteilnehmer im Hinblick auf das psychische Befinden, während die Unterschiede im körperlichen Befinden eher gering waren. Die Konsequenzen für die psychosoziale Versorgung werden diskutiert.

A Communicative Conception of Moral Appraisal

I argue that our acts of moral appraisal should be communicative. Praise and blame should communicate, to the appraised, information about their status and competences as moral agents; that they are recognised by the appraiser as a competent moral agent, and thus a legitimate candidate for appraisal. I argue for this thesis by drawing on empirical data about factors that can affect motivation. On the basis of such data, I formulate a constraint, and argue that two prominent models of moral appraisal – a consequentialist model and Wallace’s ‘evaluative response’ model – violate this constraint. The model that I propose – the communicative conception of appraisal – does not violate this constraint. This conception, I argue, can provide a fuller picture of the role of appraisals in deepening agents’ commitment to moral norms. On this model, praise and blame has not only an evaluative component, but also communicates to the agent competence affirming information.

Activation of cannabinoid CB1 receptors in the central amygdala impairs inhibitory avoidance memory consolidation via NMDA receptors

In the present study, we investigated the influence of bilateral intra-central amygdala (intra-CeA) microinjections of N-methyl-d-aspartate (NMDA) receptor agents on amnesia induced by a cannabinoid CB1 receptor agonist, arachydonilcyclopropylamide (ACPA). This study used a step-through inhibitory (passive) avoidance task to assess memory in adult male Wistar rats. The results showed that intra-CeA administration of ACPA (2 ng/rat) immediately after training decreased inhibitory avoidance (IA) memory consolidation as evidenced by a decrease in step-through latency on the test day, which was suggestive of drug-induced amnesia. Post-training intra-CeA microinjections of NMDA (0.0001, 0.001 and 0.01 μg/rat) did not affect IA memory consolidation. However co-administration of NMDA with ACPA (2 ng/rat) prevented the impairment of IA memory consolidation that was induced by ACPA. Although post-training intra-CeA administration of the NMDA receptor antagonist, d-(−)-2-amino-5-phosphonopentanoic acid (d-AP5; 0.01, 0.05 and 0.1 μg/rat) alone had no effect, its co-administration with an ineffective dose of ACPA (1 ng/rat) impaired IA memory consolidation. Post-training intra-CeA microinjection of an ineffective dose of d-AP5 (0.01 μg/rat) prevented an NMDA response to the impaired effect of ACPA. These results suggest that amnesia induced by intra-CeA administration of ACPA is at least partly mediated through an NMDA receptor mechanism in the Ce-A.     

The role of spatial configuration in tests of working memory explored with functional neuroimaging

While the importance of the prefrontal cortex for "higher-order" cognitive functions is largely undisputed, no consensus has been reached regarding the fractionation of functions within this region. Several recent functional neuroimaging studies have suggested that the mid-ventrolateral frontal cortex may play an important role in various aspects of human memory. Thus, similar patterns of activation have been observed in this region during analogous spatial, verbal and visual span tasks. In the present study, however, activation was observed in a more dorsolateral region of the lateral frontal cortex during a modified version of the spatial span task, which differed only in the spatial configuration of the array employed. The results of a supplementary behavioral study, designed to investigate this effect further, suggest that in spatial memory tasks certain stimulus configurations may encourage subjects to adopt mnemonic strategies, which may depend upon dorsolateral, rather than ventrolateral, regions of the frontal cortex. These findings shed further light on the functional relationship between dorsal and ventral regions of the lateral frontal cortex and, more specifically, how the "executive" processes assumed to be dependent upon these regions might contribute to aspects of human memory.     

The long-term effects of mild head injury on short-term memory for visual form, spatial location, and their conjunction in well-functioning university students

Research has suggested the presence of subtle long-term cognitive changes in otherwise well-functioning individuals who have previously sustained a mild head injury (MHI). This paper investigated the long-term effects of MHI on visual, spatial, and visual-spatial short-term memory in well-functioning university students. Sixteen students who reported having sustained a MHI were compared to 16 controls on tests of short-term memory (STM) for abstract polygons in haphazardly arranged locations. The three tests differed only in the requirements for recall (shapes for the visual task, locations for the spatial task, and the shapes in their respective locations for the visual-spatial task). MHI participants were selectively impaired on spatial memory, suggesting that tasks of spatial STM may be more sensitive, compared to tasks of visual STM, to the subtle long-term cognitive changes that may be present after a MHI.     

Gruppenpsychotherapie für Brustkrebspatientinnen

Zusammenfassung  Der Brustkrebs erzwingt geradezu unsere Aufmerksamkeit mit seiner hohen Prävalenz—30% aller Krebsneuerkrankungen bei nordamerikanischen Frauen sind Brustkrebs—, und er ist die zweithäufigste Todesursache bei Frauen in Nordamerika. Weiße nordamerikanische Frauen haben ein Risiko von 1:9, im Laufe ihres Lebens an Brustkrebs zu erkranken. Es gibt zahlreiche Anknüpfungspunkte, darunter genetische und familiäre Prädisposition, primäre Krebserkrankung/Langzeitüberleben und rezidivierende oder metastasierende Krankheit. Brustkrebs ist eine Krankheit, bei der jede Form der Krebsbehandlung eingesetzt wird—Chirurgie, Chemotherapie, Bestrahlung, Hormontherapie und die viel versprechenden, kürzlich entwickelten immunologischen Interventionen. Zugleich ist die Brust als Körperteil kulturell hochgradig besetzt und als Symbol der Weiblichkeit, der Attraktivität, der Sexualität und der Fortpflanzung aufmerksam und emotional viel beachtet. In der vorliegenden Arbeit wird die Anwendung von Gruppenpsychotherapien auf dieses Spektrum klinischer Belange diskutiert.

New Factor Structure of the Interpretation of Intrusions Inventory with University Students

The Obsessive Compulsive Cognitions Working Group (OCCWG) created the Interpretation of Intrusions Inventory (III) to measure appraisals (interpretations) of mental intrusions. Validation attempts by the OCCWG suggest that the three appraisal mechanisms hypothesized to comprise the III are better described as a single construct. The underlying factor structure of the III was investigated with university students (n = 307). Confirmatory factor analyses were conducted on the theoretically-derived three-factor model and on the empirically-derived one-factor model of the III. Both models failed to adequately fit the data. Thus, an exploratory factor analysis was conducted, which produced a two-factor model consisting of appraisals of Responsibility and Importance/Control of Thoughts. The new factors exhibited good predictive validity, as they predicted the severity of obsessive-compulsive symptoms and subtypes of obsessive-compulsive disorder (OCD).

A Comparison of Stress Measures in Children and Adolescents: A Self-Report Checklist Versus an Objectively Rated Interview

A self-report checklist assessing the occurrence of stressful life events in children and adolescents' lives was compared to an objectively rated interview to determine whether the checklist would introduce over-reporting of events or over-rating of event severity as a function of child/parent depressive symptoms, cognitive vulnerability, or anxiety. Participants completed the Children's Life Events Scale (CLES), the Life Events Interview (LEI), and questionnaires assessing cognitive vulnerability and symptoms of depression and anxiety. Findings yielded a positive association between the checklist and the interview. Contrary to hypotheses, depressive symptoms, cognitive vulnerability, and anxiety were not associated with over-reporting of events. Anxiety was associated with over-rating of event severity in parents but not children. Findings suggest that the checklist and interview may be equally viable approaches to assessing the occurrence of life events. Findings have mixed implications with regard to assessing event severity, as subjective reports may be systematically influenced by anxiety.

Hairpulling and Skin Picking in Relation to Affective Distress and Obsessive-Compulsive Symptoms

The current study examined the frequency and associated distress of both hairpulling and skin picking behaviors in 1,324 college students using the Massachusetts General Hospital Hairpulling Scale (MGHHS) and Skin Picking Scale (SPS). In this sample, many participants reported significant distress secondary to both hairpulling and skin picking. Participants who endorsed relatively frequent hairpulling or skin picking (N = 72) were scheduled for a follow-up testing session to further assess the relationship between these behaviors and measures of affective distress. Compared to a control sample, the follow-up sample endorsed significantly more symptoms of anxiety and stress reactivity, and had higher scores on a measure of obsessive-compulsive symptoms.
