Development of the Weight- and Body-Related Shame and Guilt Scale (WEB–SG) in a Nonclinical Sample of Obese Individuals

In this article, we present the evaluation of the psychometric properties of a new self-report measure of Weight- and Body-Related Shame and Guilt (WEB–SG). The main purpose of the study was to measure shame and guilt feelings separately in obese individuals and investigate differing behavioral and emotional correlates of these emotions. Altogether, 331 obese participants completed the WEB–SG and other established self-report measures. A subset of the participants completed a 6-month follow-up. The WEB–SG proved to be internally consistent and temporally stable over a 6-month period. Regarding the factorial structure, a two-factor conceptualization was supported. The construct validity of the WEB–SG subscales was evidenced by a substantial overlap of common variance with related measures. The subscales Shame and Guilt showed differential correlation patterns to other scales. The WEB–SG is a brief, psychometrically sound measure for assessing body shame and guilt concerning weight control in obese individuals.     

The Power of Expectation – Understanding the Placebo and Nocebo Phenomenon

Although placebo pills are supposed to have no pharmacological activity, people taking placebo pills describe a variety of positive (i.e., placebo phenomenon) and negative (i.e., nocebo phenomenon) reactions. This has major clinical implications. Placebo reactions account for a substantial part of improvement when treating patients with hypertension, mental disorders, and even after surgical procedures. The nocebo phenomenon on the other hand is responsible for non‐compliance and discontinuation of many pharmaceutical interventions. Mechanisms that underlie the placebo and nocebo effects may be related to expectation and/or classical conditioning, but some methodological issues should also be considered. Most experimental studies investigating the placebo effect have used paradigms to induce ‘placebo analgesia’, the reduction of pain perception after receiving an inert substance and an instruction that this medication would relieve pain. This paradigm allows investigators to examine the neurobiological circuitry of the placebo response using neuroimaging techniques.     

Zur Inanspruchnahme medizinischer Leistungen bei Patienten mit somatoformen Störungen

Zusammenfassung Somatoforme Störungen sind für das Gesundheitssystem sowohl wegen ihrer hohen Prävalenz und auch wegen der intensiven Inanspruchnahme medizinischer Leistungen von großer Bedeutung. Auch bei psychotherapeutischen Interventionen muss dies berücksichtigt werden, da eine Normalisierung des Inanspruchnahmeverhaltens ein zentrales Behandlungsziel sein sollte. In der vorliegenden Studie wurden Häufigkeit ambulanter Arztbesuche und Variablen des Inanspruchnahmeverhaltens untersucht. Insgesamt wurden 295 Allgemeinarztpatienten mit mindestens zwei organisch nicht hinreichend begründbaren Beschwerden in die Studie aufgenommen. Psychische Störungen und die Inanspruchnahme des Versorgungssystems wurden mit einem strukturierten Interview erhoben; daneben wurden zahlreiche Fragebögen eingesetzt. Die Mehrheit (82%) der untersuchten Patienten erfüllte die Kriterien von mindestens einer somatoformen Störung. Die Anzahl der Arztbesuche in den letzten 6 Monaten belief sich im Mittel auf 15 Kontakte. Sie korrelierten mit der Anzahl somatoformer Symptome, dem Alter, Gesundheitsängsten, genereller Angst und Depressivität. Die Regressionsanalyse bestätigt nur die Symptomanzahl und das Alter als signifikante Prädiktoren des Inanspruchnahmeverhaltens. Implikationen für die Therapie dieser Patientengruppe unter besonderer Berücksichtigung des Hausarztes werden diskutiert.     

Understanding causation

Theoretische Lücken der Cognitive Science

Theoretical gaps of the cognitive science. First of all the gap-thesis is based on a criticism 1. of the computer-orientated cognitive science (it confuses information with the information carrier), 2. of connectivism (its linguistic borrowing from the neurobiology is not appropriate), 3. of Varelas production model (the elimination of the function of representation results in the loss of the cognitive ability). From the context of meaning and time, then the author sketches a cognitive theoretical approach, in which thinking as a (symbolic and/or subsymbolic) representation of meaning is introduced, which develops in a three-digit relation between world, language and substrate on the basis of isomorphy of time. This revised version was published online in August 2006 with corrections to the Cover Date.     

Loss of control eating and psychological maintenance in children: An ecological momentary assessment study

Objective

Recent research suggests that binge eating is a common experience in youth. However, it remains largely unknown how children's binge eating presents in everyday life and which psychological factors serve to maintain this binge eating.

Methods

Children aged 8-13 years with binge eating (n = 59), defined as at least one episode of loss of control (LOC) over eating within the past three months, and 59 matched children without LOC history were recruited from the community. Following a combined random- and event-sampling protocol, children were interviewed about their day-to-day eating behavior, mood, and eating disorder-specific cognitions using child-specific cell phones during a 4-day assessment period in their natural environment.

Results

LOC episodes led to a significantly greater intake of energy, particularly from carbohydrates, than regular meals of children with and without LOC eating. While LOC episodes were preceded and followed by cognitions about food/eating and body image, there was minimal evidence that negative mood states were antecedents of LOC eating.

Conclusions

The results provide support for the construct validity of LOC eating in children. Maintenance theories of binge eating for adults apply to children regarding eating disorder-specific cognitions, but the association with affect regulation difficulties requires further investigation.     

Psychometric properties of the German version of the Barratt Impulsiveness Scale, Version 11 (BIS-11) for adolescents

Impulsiveness is increasingly gaining attention as a potential risk factor for various mental disorders. Until now, there have been German instruments that allowed for assessing adolescents' self-reported impulsiveness multi-dimensionally. The present study examined the German version of the Barratt Impulsiveness Scale-11 (BIS-11) for adolescents. The instrument was completed by 659 adolescents ages 10 to 20 years; 98 were retested after 6 months. Items showed adequate psychometric properties. An exploratory factor analysis identified three factors that showed slightdifferences from the initial questionnaire proposed by Barratt. The factors showed low to moderate intercorrelations, satisfactory internal consistency (dependent on factor), and were stable over time. Convergent validity was ascertained, and the item pool showed sufficient power to discriminate adolescents with symptoms of attention deficit hyperactivity disorder and those with loss of eating control from healthy adolescents. Findings suggest that the German BIS-11 is appropriate for reliable investigation of impulsiveness in adolescents. Future research should examine sensitivity as a screening tool, as well as sensitivity to change.     

Intact emotion-induced recognition bias in neuropsychological patients with executive control deficits

In recognition memory tasks, emotionally negative words are judged more often as "old" relative to emotionally neutral words, suggesting a shift in response bias. We wondered whether this bias shift was due to the flexible regulation of executive control during memory retrieval. To address this question, we investigated individuals with high variability in executive control functions. As expected, we observed that emotional word meaning did indeed have a strong influence on the bias toward responding "old," independent of recognition accuracy and overall response bias. However, these effects were uncorrelated with executive control, as measured by the Trail Making Test, and were fully intact, even in a sample of hospitalized neurological patients with severe executive dysfunctions, some of whom had marked damage in fronto-thalamo-striatal networks. Having concluded that the emotion-induced bias must develop on different grounds, we went on to discuss alternative explanations.
