The aim of this study is to describe the factor structure and psychometric properties of an extended version of the Children’s Automatic Thoughts Scale (CATS), the CATS-Negative/Positive (CATS-N/P). The CATS was originally designed to assess negative self-statements in children and adolescents. However, positive thoughts also play a major role in childhood disorders such as anxiety and depression. Therefore, positive self-statements were added to the CATS. The CATS-N/P was administered to a community sample of 554 children aged 8–18 years. The results of a confirmatory factor analysis revealed that the positive self-statements formed a separate and psychometrically sound factor. Internal and short-term test–retest reliability was good. Boys reported more hostile and positive thoughts than girls; and younger children reported more negative thoughts concerning physical threat, social threat, and failure than older children. In conclusion, the results of the current study support the use of the CATS-N/P for the measurement of positive and negative thoughts in children. The application of the CATS-N/P can facilitate further research on cognitive factors in different childhood disorders.

Results BAS drive was positively associated with daily intakes of SSBs (13.79 %, p < 0.01), unhealthy snacks (5.42 %, p < 0.001), and energy and nutrients derived from SSBs (p < 0.001) and snacks (p < 0.01). BAS reward responsiveness (RR) was only positively associated with intake of unhealthy snacks (3.85 %, p < 0.05), healthy snacks (6.41 %, p < 0.05), and fat (4.05 %, p < 0.01) and Na (3.89 %, p < 0.05) from snacks. Interaction effects of gender and BAS RR (p < 0.05) were found. Significant positive associations between BAS RR and daily intakes of energy from snacks (6.48 %, p < 0.01) and fat from snacks (7.22 %, p < 0.001) were found only for girls. Conclusion SR was associated with snack and SSB consumption in adolescents, especially in girls. These findings suggest that SR should be taken into account when designing interventions to improve the snack and SSB intake of adolescents.

The purpose is to investigate whether a change in putative mediators (negative and positive thoughts, coping strategies, and perceived control over anxious situations) precedes a change in anxiety symptoms in anxiety-disordered children and adolescents receiving cognitive behavioral therapy (CBT). Participants were 145 Dutch children (8-18 years old, M = 12.5 years, 57% girls) with a primary anxiety disorder. Assessments were completed pretreatment, in-treatment, posttreatment, and at 3-month follow-up. Sequential temporal dependencies between putative mediators and parent- and child-reported anxiety symptoms were investigated in AMOS using longitudinal Latent Difference Score Modeling. During treatment an increase of positive thoughts preceded a decrease in child-reported anxiety symptoms. An increase in three coping strategies (direct problem solving, positive cognitive restructuring, and seeking distraction) preceded a decrease in parent-reported anxiety symptoms. A reciprocal effect was found for perceived control: A decrease in parent-reported anxiety symptoms both preceded and followed an increase in perceived control. Using a longitudinal design, a temporal relationship between several putative mediators and CBT-outcome for anxious children was explored. The results suggest that a change in positive thoughts, but not negative thoughts, and several coping strategies precedes a change in symptom reduction and, therefore, at least partly support theoretical models of anxiety upon which the anxiety intervention is based.

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.

The intervention was not able to improve adolescents' snack choices, due to low reach and exposure. Future interventions should consider multicomponent interventions, teacher engagement, exhaustive participatory app content development and tailoring.

BackgroundAs the snacking pattern of European adolescents is of great concern, effective interventions are necessary. Till now health promotion efforts in children and adolescents have had only limited success in changing adolescents’ eating patterns and anthropometrics. Therefore, the present study proposes an innovative approach to influence dietary behaviors in youth based on new insights on effective behavior change strategies and attractive intervention channels to engage adolescents. This article describes the rationale, the development, and evaluation design of the ‘Snack Track School’ app. The aim of the app is to improve the snacking patterns of Flemish 14- to 16-year olds.MethodsThe development of the app was informed by the systematic, stepwise, iterative, and collaborative principles of the Intervention Mapping protocol. A four week mHealth intervention was developed based on the dual-system model with behavioral change strategies targeting both the reflective (i.e., active learning, advance organizers, mere exposure, goal-setting, monitoring, and feedback) and automatic processes (i.e., rewards and positive reinforcement). This intervention will be evaluated via a controlled pre-post design in Flemish schools among 1400 adolescents.DiscussionWhen this intervention including strategies focused on both the reflective and automatic pathway proves to be effective, it will offer a new scientifically-based vision, guidelines and practical tools for public health and health promotion (i.e., incorporation of learning theories in intervention programs).Trial registrationNCT02622165 registrated November 15, 2015 on clinicaltrials.gov.
