General self-efficacy is a central personality trait often evaluated in surveys as context variable. It can be interpreted as a personal coping resource reflecting individual belief in one’s overall competence to perform across a variety of situations. The German-language Allgemeine-Selbstwirksamkeit-Kurzskala (ASKU) is a reliable and valid instrument to assess this disposition in the German-speaking countries based on a three-item equation. This study develops a French version of the ASKU and tests this French version for measurement invariance compared to the original ASKU. A reliable and valid French instrument would make it easy to collect data in the French-speaking countries and allow comparisons between the French and German results. Data were collected on a sample of 1,716 adolescents. Confirmatory factor analysis resulted in a good fit for a single-factor model of the data (in total, French, and German version). Additionally, construct validity was assessed by elucidating intercorrelations between the ASKU and different factors that should theoretically be related to ASKU. Furthermore, we confirmed configural and metric as well as scalar invariance between the different language versions, meaning that all forms of statistical comparison between the developed French version and the original German version are allowed.

OBJECTIVES: This study compares the effects of progressive muscle relaxation and an imagery-based relaxation training on childrens' physiological and subjective responses in a randomized controlled trial. DESIGN: Sixty-four children aged 9 to 13 years were randomly allocated to either one of three experimental conditions: progressive muscle relaxation, imagery-based relaxation or a control condition (neutral story). There were five training sessions in each condition. METHOD: Heart rate (HR), skin conductance level (SCL), and skin temperature (ST) were measured continuously during a 5-minute baseline period, an 8-minute relaxation training period, and a 5-minute follow-up in each session. In addition, subjective ratings of mood and physical well-being were collected intermittently. RESULTS AND CONCLUSIONS: A physiological pattern indicating relaxation was most clearly associated with the imagery-based relaxation approach (decreases in HR and SCL), although ST remained unchanged. In contrast, progressive muscle relaxation led to an increase in HR during the training. The neutral story condition showed a similar trend as the imagery-based relaxation approach (although not reaching statistical significance). Furthermore, children's ratings of positive mood and physical wellbeing increased during baseline and training periods, but there were no differences between training conditions. The results indicate psychophysiological effects of relaxation instructions which, however, are not specific for systematic relaxation training. [less ▲]

Objective: The aim of the present study was to investigate psychophysiological responses to food exposure in binge eaters. Method: Thirty female volunteers reporting regular binge attacks were compared with 30 nonbinge eaters. Subjects attended individually for the single laboratory session. Continuous measures of heart rate (HR), blood pressure (BP), electroder- mal activity (EDA), and respiration rate were taken during rest and exposure to their favorite binge food. In addition, psychophysiological monitoring continued while subjects were al- lowed to eat after food exposure. Participants also completed inventories assessing restrained eating style (FEV, Revised Restraint Scale). Ratings of nervousness, distress, desire to binge, and hunger were collected repeatedly throughout the experiment. Results: The results indi- cate higher psychophysiological arousal in binge eaters than in nonbinge eaters. Binge eaters maintained a higher arousal level in BP and EDA throughout the food exposure trial than controls. HR during food exposure predicted the relative amount of food consumed during the eating trial across all subjects. This relationship, however, was more pronounced in binge eaters than controls and in restrained compared to unrestrained binge eaters. Discussion: The implications of these results are discussed in terms of conditioning and arousal models of cue reactivity in binge eating. © 1997 by John Wiley & Sons, Inc.

Psychophysiologische Indikatoren für Interozeption: Kognition und Klinik

Interozeption – die Wahrnehmung von Körpersignalen – spielt bei vielen psychologischen Prozessen eine wichti-ge Rolle, z.B. beim subjektiven Erleben von Emotionen oder bei der Symptomgenese körperbezogener psychi-scher Störungen. Neben Herzschlagdetektionstests, die als Indikator für die interozeptive Genauigkeit heran-gezogen werden, existieren außerdem einige psychophy-siologische Methoden für die Erfassung interozeptiver Prozesse, wie Herzschlag-evozierte Potenziale, respira-torische Widerstände oder die Kopplung von Stimulus-präsentation an den kardialen Zyklus. Ziel dieses Sym-posiums ist es, neue Erkenntnisse zu psychophysiolo-gischen Mechanismen von Interozeption zu präsentieren, die auf unterschiedliche viszerale Organe zurückgehen, sowie deren Integration in normales und pathologisches Erleben und Verhalten zu diskutieren. Zunächst wird Thomas M. Schilling (Universität Trier) den Einfluss von baro-afferenter neuronaler Signalüber-mittlung auf die Integration multisensorischer Stimuli diskutieren. Daraufhin präesentiert Sibylle Petersen (KU Leuven) Ergebnisse zu Effekten von Kategorisierung von Atemwiderständen auf Wahrnehmung und Atem-verhalten, sowie Zusammenhang dieser Effekte mit Furcht vor interozeptiven Reizen. Zoé van Dyck (Uni-versität Luxemburg) wird anschließend einen Vortrag zum Einfluss von kurzzeitiger Nahrungsdeprivation auf die Herzschlagdetektionsgenauigkeit halten. Von Laura Müller (Universitätsklinikum Heidelberg) werden Daten zu Herzschlag-evozierten Potenzialen als Indikatoren für die kortikale Verarbeitung afferenter Signale aus dem kardiovaskulären System bei Boderline-Persönlichkeits-störung im Vergleich zu Gesunden präsentiert. Zum Abschluss diskutiert André Schulz (Universität Luxem-burg) Konvergenzen und Divergenzen von interozepti-ven Selbstberichten, Herzschlagdetektionsgenauigkeit und Herzschlag-evozierter Potenziale bei Depersonalisa-tions-/Derealisationsstörung im Vergleich zu Gesunden.
