OBJECTIVE: The present study was designed to investigate the psychophysiologic effects of "Applied Tension" (AT) on the emotional fainting response to blood and injury in a controlled experiment. METHOD: Twenty-two persons reporting to generally feel faint or to have fainted at the sight of blood or injury and 22 participants classified as Non-Fainters were randomly allocated to a treatment or control condition. Psychophysiologic responses were continuously monitored while individuals watched a video depicting open-heart surgery and a control film. Prior to the surgery film, participants in the treatment condition were instructed in the use of AT. RESULTS: All participants classified as Fainters showed a diphasic response pattern while watching the surgery film. This response, however, was significantly attenuated in Fainters in the treatment condition. CONCLUSIONS: These results suggest that AT provides an effective treatment strategy for the prevention of fainting responses in persons with a fear of blood and injury. [less ▲]

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.

This study examined psychophysiological stress responses to idiosyncratically relevant stress in bulimia nervosa (BN) and binge eating disorder (BED), in relation to autonomic cardiac control and nutritional status. A total of 81 women with BN, BED and healthy controls (HC) took part in an in sensu exposure to idiosyncratic stress. Psychological and peripheral physiological parameters were measured, and tonic heart rate variability, nutritional status, and types of stress were determined. In response to stress exposure, both eating disordered groups showed a stronger reactivity of sadness, and the BED group showed a stronger reactivity of insecurity than the HC group. Desire to binge was increased in the context of interpersonal stress. Stress exposure led to increased cardiovascular activity and reduced electrodermal activity that did not differ by group. The BN-specific symptomatology moderated the association between autonomic cardiac control and psychophysiological stress responses. The results suggest common and specific psychophysiological processes in symptom maintenance through life stress in BN and BED. [less ▲]

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.

gaming disorder (IGD) has been related to a wide range of detrimental psychological and health consequences. The purpose of the present pilot study was to test the direct and indirect relationships between IGD and emotional trauma, body image dissatisfaction, social anxiety, loneliness, depression, and self-esteem. A total of 242 online gamers completed a survey comprising a comprehensive battery of psychometric self-report scales concerning aforementioned variables. Results indicated that IGD was significantly correlated with all the variables except for body image dissatisfaction. Path analysis indicated an indirect relationship between childhood emotional trauma and IGD through depressive symptoms, while adjusting for gender, age, and number of hours gaming. The findings of the present study indicate that online gamers with a history of emotional abuse and/or neglect have higher levels of depressive symptoms, and that depressive symptoms are important risk factors of IGD.

BACKGROUND: In Luxembourg, the extensive phenomenon of school dropout is a prime policy concern in the light of individual, social and economic consequences. Although the authorities report an overall decrease of the national dropout rate, the proportion of early school leavers who remain without any specific occupation is still alarming. Therefore, this study intends a shift of focus from system-inherent to individual factors, including mental health and family correlates, to provide a more comprehensive analysis of the dropout phenomenon. METHODS/DESIGN: The objectives of this study are to investigate the type and prevalence of psychiatric disorders among school dropouts and to compare the findings with those by a matched control group of regularly enrolled students. Furthermore, family variables and socioeconomic status will be analysed, as they are factors likely to interfere with both educational attainment and mental health. A trained psychologist will use structured interviews and self-report forms to investigate for mental health issues, information on schooling, socioeconomic situation and family life. Controls will be matched for gender, age, school type and educational grade. DISCUSSION: As school dropouts face a serious risk of long term professional and social marginalization, there is an evident need for action. Identifying psychosocial risk and protective factors of school dropout will deliver solid insight on how to conceive public health strategies for young people who may need a more customized support to carry out their academic potential.

Previous results from our laboratory suggest a combined effect of anger-suppression and family history of cardiovascular disorders in determining cardiovascular responses to mental stress. The present study was designed to determine the effect sizes in cardiovascular reactivity associated with biological risk, psychological risk and the combination of these risk factors using meta-analytical techniques. Results from three independent studies with almost identical experimental procedures provided the basis for the calculation of d, the difference between the means of two groups, divided by the pooled within-group standard deviation. Effect sizes were calculated for the comparison of high versus low biological hypertension risk, high versus low anger suppression, and high versus low combined risk. The results show the largest effect sizes for the comparison of high versus low combined risk. The effect sizes associated with the combination of risk factors were larger than the sum of the effect sizes associated with either factor alone. We conclude that the combination of biological and psychological risk factors in determining cardiovascular reactivity to mental stress is more than the sum of its parts. These findings are discussed in terms of a better understanding of the over-additive effects of multiple cardiovascular risk factors on cardiovascular morbidity and mortality. [less ▲]

Protein Topology Graph Library (PTGL) is a database application for the representation and retrieval of protein topologies. Protein topologies are based on a graph-theoretical protein model at secondary structure level. Different views on protein topology are given by four linear notations for their characterization. Protein topologies can be derived at different description levels considering alpha- and beta-structures. The on-line search tool is based on an object-relational database and provides a query browser for data interrogation by string patterns, keyword queries and sequence similarity. Protein topologies are represented both as schematic diagrams and as three-dimensional images. [less ▲]
