The behavioral Inhibition system in childhood and adolescent anxiety: an analysis from the information processing perspective

Iedereen kent wel kinderen met een angstig temperament: kinderen die snel schrikken, moeilijk te troosten zijn, of verlegen en teruggetrokken zijn. De meesten van die kinderen groeien daar uit. Anderen blijven angstig en bang. Sommigen krijgen zelfs last van echte angststoornissen, die hen hinderen in hun dagelijks leven. Leentje Vervoort onderzocht het verband tussen een angstig temperament en angststoornissen. Ze deed dat door te kijken naar de manier waarop kinderen met en zonder angstproblemen omgaan met informatie uit de buitenwereld. Vervoort concludeert dat kinderen met een angststoornis sneller hun bezigheden staken dan kinderen zonder angstproblemen wanneer ze geconfronteerd worden met enge dingen. Daarnaast vond ze dat kinderen met een angststoornis enge dingen beduidend negatiever evalueren dan kinderen zonder angststoornissen De laatste groep vindt enge dingen niet negatiever dan gewoon negatieve dingen. Ten slotte keek Vervoort hoe de aandacht voor enge dingen verschilt tussen kinderen met en zonder angstproblemen. Hoewel vaak gedacht wordt dat temperament iets is wat we niet kunnen veranderen, lijkt het er toch op dat kinderen met een angstig temperament ‘beschermd' kunnen worden tegen angstproblemen door de manier waarop kinderen omgaan met informatie uit de buitenwereld aan te pakken

Food approach and food avoidance in young children : relation with reward sensitivity and punishment sensitivity

It has recently been suggested that individual differences in Reward Sensitivity and Punishment Sensitivity may determine how children respond to food. These temperamental traits reflect activity in two basic brain systems that respond to rewarding and punishing stimuli, respectively, with approach and avoidance. Via parent report questionnaires, we investigate the associations of the general motivational temperamental traits Reward Sensitivity and Punishment Sensitivity with Food Approach and Food Avoidance in 98 preschool children. Consistent with the conceptualization of Reward Sensitivity in terms of approach behavior and Punishment Sensitivity in terms of avoidance behavior, Reward Sensitivity was positively related to Food Approach, while Punishment Sensitivity was positively related to Food Avoidance. Future research should integrate these perspectives (i.e., general temperamental traits Reward Sensitivity and Punishment Sensitivity, and Food Approach and Avoidance) to get a better understanding of eating behavior and related body weight

A reinforcement sensitivity perspective on adolescents' susceptibility to the influence of soap opera viewing on alcohol attitudes

Previous research found support for an association between exposure to alcohol-related media content and alcohol attitudes, intentions and behavior. Nevertheless, research on what makes young people susceptible to the occurrence of this relationship is scarce. The current study examined the behavioral activation (BAS) and inhibition system (BIS) as moderators of the relationship between soap opera viewing and alcohol attitudes. A cross-sectional survey was carried out among a sample of 922 adolescents (M-age=14.96years, SD=.85, 56% girls). Regression analyses showed no association between total television viewing and alcohol attitudes, but did confirm that soap opera viewing is associated with positive attitudes towards alcohol use. Moderation analyses indicated that BAS did not moderate this relationship, while BIS did; the relationship between soap opera viewing and positive attitudes toward alcohol was only significant for adolescents with a low BIS-profile. These results provide support for the premise that an elevated BIS protects adolescents from the effect of soap opera viewing frequency on their alcohol attitudes

Maladaptive eating in children and adolescents with obesity : scrutinizing differences in inhibition

Introduction In order to grasp the complex etiology of childhood obesity, we aim to clarify the relationship between external eating and weight. Based on theory and empirical evidence, we claim that inhibition is an important moderator in this association. In our first research question we expected that high external eating would be related to a higher weight status, especially for those with high inhibition problems. Secondly, we explored the moderating role of inhibition in the association between external eating and weight change after a multidisciplinary obesity treatment. Method We investigated n=572 participants (51% boys, aged 7-19) with moderate to extreme obesity recruited in a Belgian inpatient treatment center. At intake, parents reported on inhibition (BRIEF), while the children and adolescents reported on their eating behavior (DEBQ). Weight and length were objectively measured pre and post treatment (ADJUSTED BMI). Two hierarchical linear regression models were built to scrutinize the influence of inhibition on the association between external eating and both baseline weight and weight change. Results First, predicting baseline weight, we found no significant moderating effect of inhibition problems. Second, predicting weight loss, inhibition turned out to be a substantial moderator, specifically in adolescents. Some unexpected gender differences occurred in favor of adolescent boys, in a way that those with high external eating and low inhibition problems lost most weight. Conclusion Inhibition problems act as a moderator explaining weight loss, but this only holds for adolescents. This suggests that external eating and inhibition play a complex role in weight loss in certain age and gender categories, and stresses the importance of identifying subgroups for tailoring interventions. For those with high inhibition problems, interventions aimed at increasing inhibition skills might be needed to optimize treatment outcomes

Using confidence interval-based estimation of relevance to explore bottom-up and top-down determinants of problematic eating behavior in children and adolescents with obesity from a dual pathway perspective

Prevalence of overweight and obesity in children and adolescents is high, not only in Western countries but also in developing countries. Efforts to improve prevention and treatment programs are needed. Given their essential role in weight problems, knowledge of determinants of problematic eating behavior ('External Eating' and 'Emotional Eating') is crucial for intervention development. Inspired by Appelhans' Dual Process Theory of Eating Behavior, the present study evaluated the importance of top-down regulative capacities and bottom-up reactivity, using the CIBER approach. CIBER is an innovative statistical approach to test the importance of behavior determinants, based on confidence intervals, instead of significance testing of point estimates. Survey data on different aspects of executive functioning (as indices of regulative capacities: Inhibition, Cognitive Flexibility, Emotional Control, Initiation, Working Memory, Planning/Organizing, Organization of materials, and Monitoring) and reward sensitivity (as an index of reactivity) were collected in a large sample of children and adolescents (n = 572) with severe obesity (adjBMI > 180%). Results showed that Emotional Eating is determined by Emotional Control, while External Eating is determined by Reward Sensitivity. The finding that differential mechanisms underlie different aspects of problematic eating suggests the need for using tailored intervention techniques to address altered reactivity and weak regulative capacities

Disposition-content congruency in adolescents' alcohol-related social media (self-) effects : the role of the five-factor model

Objective: Accumulating evidence indicates that social networking sites play an increasingly important role in young people's drinking behavior. The present study adds to this research by assessing the conditionality of the relationships between exposure to and self-sharing of alcohol-related content on social media and adolescents' drinking behavior. Specifically, the moderating role of the five-factor model of personality is determined. Method: A cross-sectional survey study was conducted among 866 mid-adolescents (Msubsample = 14.85 years, SD = 0.71, 57.5% girls). Polynomial regression analysis with response surface modeling was used to test the interactions. Results: Exposure, but not self-sharing, was directly associated with more alcohol consumption. However, it appeared that the act of sharing was more important than the frequency of sharing. Next, the relationship between exposure and consumption was not found to be moderated by personality. In contrast, there were significant linear and nonlinear interactions between self-sharing and all five personality traits. Individuals who are predisposed to engage in more alcohol consumption experience a stronger association between self-sharing and their drinking behavior. Conclusions: Social media can play a role in adolescents' drinking behavior, but this role is partially dependent on temperamental predispositions
