RESUMEN

Research suggests that body dissatisfaction is common among children. However, it remains largely unknown how body dissatisfaction occurs on a daily basis and which environmental factors are linked to this. The purpose of this study was to examine (1) state body dissatisfaction, dietary restraint, compensatory exercise and loss of control eating among children and its association with upward comparisons via social media and (2) whether trust in parents may attenuate this association. Children from 10 to 12 years old (N = 50) were assessed three times a day during a two-week period. Trust was examined via a baseline questionnaire. State body dissatisfaction, dietary restraint, compensatory exercise, loss of control eating and upward comparisons were examined via Ecological Momentary Assessment (EMA). Multilevel analyses indicated that an a higher level of upward comparison is associated with a higher level of state body dissatisfaction, compensatory exercise and loss of control eating. Trust in father significantly moderated the association between appearance comparison and body dissatisfaction. No evidence was found for the protective role of trust in mother. Future research is necessary to enhance our understanding of state body dissatisfaction among children and of environmental factors that may protect children from the adverse effects of social media.

RESUMEN

INTRODUCTION: In the context of understanding children's food refusal behaviors, such as food fussiness and food neophobia, research has predominantly focused on the role of parental feeding strategies. However, little is known about which general family context variables add to the understanding of children's food refusal behaviors. The purpose of this study was to examine the relation between 1) parents' own use of maladaptive emotion regulation strategies when they are anxious, 2) parents' reactions towards their children's emotions in stressful situations, and 3) parenting styles on the one hand, and children's food refusal behaviors on the other. METHODS: Mothers and fathers (N = 157) of young children (M = 4.64, SD = 1.7) completed a series of self- and parent-report questionnaires. RESULTS: The model examining the role of parenting styles was found to be significantly related to food refusal behaviors in children. More specifically, the current findings demonstrate that higher levels of a coercive parenting style were associated with higher levels of both food fussiness and food neophobia in children. Furthermore, higher levels of a chaotic parenting styles were associated with higher levels of food neophobia in children. The models examining parents' maladjusted emotion regulation strategies when anxious and parents' reactions towards their children's emotions during stressful situations were not found to be significant. CONCLUSIONS: Factors related to the parenting style appear to be important for understanding food refusal behaviors in children. Replication of the findings using longitudinal and observational designs is needed.

RESUMEN

Dual-pathway models suggest that poor self-regulation (immature regulatory combined with strong reactive processes) is an important factor underlying addictive behaviors among adolescents. This study examined whether there are different self-regulation profiles among community adolescents, and how these profiles are related to the presence, severity and comorbidity of different addictive behaviors. A community sample of 341 adolescents (54.5% female; 13-17 years) was recruited. Participants self-reported on regulatory (inhibitory control) and reactive (reward and punishment sensitivity) processes, as well as on different addictive behaviors (binge eating, tobacco-, cannabis- and alcohol use, gaming, gambling and pathological buying). A model-based clustering analysis found evidence for three meaningful profiles: 'impulsive/under-controlled', 'anxious' and 'protective'. The 'impulsive/under-controlled' profile was characterized by the highest prevalence and severity of cannabis use and the most severe alcohol use. The 'impulsive/under-controlled' and 'protective' profiles demonstrated the highest prevalence and severity of tobacco use, whereas the 'impulsive/under-controlled' and 'anxious' profiles showed the highest binge eating scores. Adolescents who reported more than three types of addictive behaviors generally belonged to the 'impulsive/under-controlled' profile. The profiles did not differ for gaming, gambling and pathological buying. The 'impulsive/under-controlled' profile emerged as the most vulnerable profile in the context of addictive behaviors (especially for binge eating and substance use).

RESUMEN

Studies have indicated that the media plays a role in the development of body dissatisfaction in children. Nevertheless, there is limited understanding of the protective factors that may reduce this association, such as the parent-child relationship. Therefore, this study investigates children's body dissatisfaction and self-esteem and the role of media pressure and a trust in parent-child relationships herein. A sample of n = 246 participants (59.8% girls, aged 8-10) was recruited. Children completed self-report questionnaires that assessed body dissatisfaction, self-esteem, media pressure, and trust in parent-child relationships. Results revealed that higher scores on media pressure were linked to increased body dissatisfaction and decreased self-esteem. On the other hand, higher scores on trust in mother and father were associated with lower levels of body dissatisfaction and higher levels of self-esteem. However, the presence of trust in parent-child relationships did not attenuate the impact of media pressure on body dissatisfaction or self-esteem. Further investigation is necessary to gain a deeper understanding of how sociocultural and interpersonal factors interact and contribute to the development of body image problems. While current prevention and intervention programs predominantly focus on the individual, it may be beneficial to place greater emphasis on the family environment.

RESUMEN

OBJECTIVE: Adolescence is a critical period for the onset of unhealthy eating habits. One important contributing factor is poor inhibitory control (IC), a cognitive skill that enables behavior regulation. IC training appears successful in countering unhealthy eating in adults, but evidence in adolescents is scarce. In addition, the mechanism of change from IC training remains unclear. Therefore, the present study aimed to assess changes in IC during a single session of IC training in adolescents. The effectiveness of the training was assessed by comparing the experimental group to a matched control group. METHOD: A community sample of 57 adolescents between 10 and 18 years was recruited (Mage = 16.61, SDage = 2.52, 73.7% girls, Madj.BMI = 105.17, SDadj.BMI = 18.81). IC was assessed before, during, and after the training using a GO/NO-GO task. Indices of IC were commission errors (CE; incorrectly responding on a no-go trial) and reaction time (RT) on go trials. RESULTS: CE rates among adolescents who received the IC training were the highest during the training and decreased significantly after the training. However, there were no differences in CE before compared to after the training. No differences were found in RT before, during or after the training. In addition, compared to the control group, the experimental group showed no significant differences in either CE or RT before, during or after the training. DISCUSSION: To the best of our knowledge, the present study is the first to assess changes in IC after an IC training in a community sample of adolescents. Results of this study further elucidate the complex role of IC in adolescents' unhealthy eating habits. Future studies should seek to corroborate these findings in a larger sample.

RESUMEN

INTRODUCTION: This study examined the moderating role of adaptive and maladaptive emotion regulation in the relationship between general perceived stress and depressive symptoms during the first coronavirus disease 2019 (COVID-19) lockdown in March-April 2020 in Belgium, while controlling for past depressive symptoms in 2016. METHODS: Participants were 110 adolescents (55% female; Mage = 16, SDage = 1.80) who filled out different questionnaires assessing maladaptive and adaptive emotion regulation strategies (ERS), perceived stress, and depressive symptoms. RESULTS: Results revealed that only maladaptive ERS statistically significantly moderated the relationship between perceived stress and depressive symptoms. More specifically, the amount of perceived stress is positively associated with the level of depressive symptoms, especially in adolescents who use more maladaptive ERS. CONCLUSION: The repertoire of adaptive ERS might not be sufficient for adolescents to flexibly cope with a highly stressful situation such as the COVID-19 pandemic and lockdown. Study findings highlight the need to support youth, particularly those who use more maladaptive ERS, in adaptively coping with intense stressful life events.

RESUMEN

INTRODUCTION: One in three adolescents frequently consume unhealthy snacks, which is associated with negative developmental outcomes. To date, it remains unclear how intrapersonal factors account for food choices in adolescents. Guided by the dual-pathway model, the current study aimed to: (1) examine the joint contribution of inhibitory control and attentional bias in predicting unhealthy food choices in adolescents, and (2) determine whether this mechanism is more pronounced in adolescents who experience loss of control over eating (LOC). MATERIALS AND METHODS: A community sample of 80 adolescents (65% female; 10-17 years old, M age = 13.28, SD = 1.94) was recruited. Based on a self-report questionnaire, 28.7% of this sample reported at least one episode of LOC over the past month. Food choice was assessed using a computerized food choice task. Both inhibitory control and attentional bias were measured with behavioral tasks (go/no-go and dot probe task, respectively). Binary logistic regressions were conducted to address the research questions. RESULTS: Inhibitory control and attentional bias did not significantly interact to predict unhealthy food choices. However, there was a significant three-way interaction between inhibitory control, attentional bias and LOC. For adolescents without LOC, the combination of poor inhibitory control and low attentional bias was significantly associated with unhealthy food choice. Surprisingly, for adolescents with LOC, there was no significant association between unhealthy food choice and inhibitory control or attentional bias. DISCUSSION: Dual-pathway processes do not seem to add to the explanation of food choice behavior for adolescents with LOC. For adolescents who do not experience LOC, those with poor inhibitory control combined with low attentional bias might be at particular risk for making unhealthy food choices.

RESUMEN

Body image problems are reported during middle childhood and are associated with exposure to appearance-focused media. This longitudinal study investigated the extent to which three media influence components, Awareness, Pressure, and Internalization of media ideals, predict body image and eating problems in children and whether gender moderates this effect. A total sample of N = 688 participants (46 % girls, aged 8-11 at T1) was studied. Self-report questionnaires were administered on the media influence components, body image and eating problems at T1 and T2 (1 year later). After controlling for age, adjusted body mass index and baseline levels of body image and eating problems, results show that media influence components significantly predicted Restraint and Concerns about Eating, Weight, and Shape one year later. Awareness, however, uniquely predicted increases in Eating Concerns in boys, while Pressure predicted increases in Concerns on Eating, Weight, and Shape in girls only. The current results indicate that media influences, some of which may be gender-specific risk factors, predict subsequent body image concerns of girls and boys during middle childhood. Thus, both boys and girls should be addressed in future research and prevention programs.

RESUMEN

OBJECTIVE: Loss of control over eating (LOC) is common among adolescents and is associated with negative developmental outcomes. Low self-regulation, and specifically low inhibitory control, is increasingly emphasized as an underlying factor in LOC. However, the specific context in which these capacities fail remains unclear. The affect regulation model proposes that negative affect may trigger LOC; however, research has mostly assessed trait negative affect using questionnaires, whereas measuring state negative affect is needed to determine its triggering role. Therefore, this study examined the interaction between inhibitory control and state negative affect in predicting LOC among adolescents using an experimental mood-induction design. METHOD: Participants were 50 adolescents (10-18 years; 76% girls) from the general community. Participants first reported on their self-regulatory and inhibitory control capacities. They were then assigned to a sad or neutral mood-induction (using a film clip), followed by a multi-item food buffet from which they could eat as much as they liked. Finally, participants reported on their experience of loss of control while eating. RESULTS: Inhibitory control (but not self-regulation in general) interacted with the mood-induction to predict LOC. Adolescents with low inhibitory control experienced significantly more LOC, but only in the sad mood condition. DISCUSSION: The experience of negative affect appears to be an important trigger for LOC in adolescents with low inhibitory control. With a view to prevention and early intervention of LOC, inhibitory control training may be most effective in contexts where adolescents experience high levels of negative affect.

RESUMEN

OBJECTIVE: Dual-pathway models propose that loss of control over eating (LOC) is the result of an imbalance between weaker regulatory and stronger reactive processes. However, these processes are generally captured with only one assessment method, leading to mixed findings. Additionally, it is unclear whether regulatory difficulties are generic or food-specific. Therefore, the aim of this study was twofold: (1) to investigate the interaction between regulatory and reactive processes in predicting the presence of LOC in adolescents, using both self-report questionnaires and behavioral tasks, and (2) to examine whether generic or food-specific regulatory processes interact with reactive processes to predict the presence of LOC. METHOD: A community sample of 295 adolescents (10-17 years; 67.2% girls; M = 13 years; SD = 1.99) was allocated to a LOC-Group (n = 93) or a NoLOC-Group (n = 202) based on a self-report questionnaire which assessed whether participants had experienced LOC over the past month (Children's Eating Disorder Examination Questionnaire). Both self-report questionnaires and behavioral tasks were used to measure regulatory (Behavior Rating Inventory of Executive Function and go/no-go task, respectively) and reactive (Behavioral Activation Scale and dot probe task, respectively) processes. Some adolescents completed a generic go/no-go task and others a food-specific version. Binary logistic regressions were conducted with LOC as the categorical dependent variable and regulatory and reactive processes (and their interaction) as the independent variables. RESULTS: In line with dual-pathway models, the combination of weaker regulatory and stronger reactive processes was associated with the presence of LOC. This was evident from both the self-report scales and the behavioral tasks. Preliminary results further suggest that regulatory difficulties seem to be food-specific. CONCLUSIONS: Our results provide multi-method evidence for the dual-pathway account of self-regulation in LOC among adolescents. Theoretical and practical implications are discussed.

RESUMEN

Impulsivity contributes to poor outcomes of existing childhood obesity treatments. Conceptualised within dual-process models, this self-regulation failure reflects the operation of strong automatic processing (heightened food responsivity) and/or weak regulatory processing (poor self-control). This systematic literature review examined the evidence for the self-regulation failure hypothesis from a dual-process models perspective to evaluate its potential for enhancing childhood obesity treatment. Searches were conducted from six databases. Eligibility criteria included: (1) recruited a child or adolescent sample; (2) measured or manipulated one or more automatic and/or regulatory processes (attentional bias, approach bias, working memory, inhibitory control, executive function); (3) used a cross-sectional, longitudinal or experimental design; and (4) included a primary outcome measure that was eating/weight related and/or pertained to the underlying process(es). The search identified 147 eligible studies. Despite methodological variations and inconsistent findings across studies, evidence points to a stronger impact of automatic processes and in particular a reduced capacity for regulatory processing in youngsters with overweight/obesity. Emerging evidence suggests that these processes can be altered by targeted training to curtail food intake and associated weight gain. An intervention protocol based on the dual-process framework has the potential to enhance current childhood obesity treatments. Recommendations for future research are provided.

RESUMEN

BACKGROUND: Reward sensitivity has been associated with adolescents' intake of unhealthy snacks and sugar-sweetened beverages. However, so far, there are no studies published describing the impact of parenting practices on this relationship. The present study will, therefore, investigate whether food parenting practices can moderate the association between reward sensitivity and diet intakes. METHOD: A cross-sectional research study was conducted among 14- to 16-year old Flemish adolescents (n = 867, age 14.7 ± 0.8 y, 48.1% boys) and a subset of their parents (n = 131), collecting data on daily intakes, reward sensitivity, and food parenting practices. Linear regression was used to assess the moderation effect of parenting practices (both adolescent- and parent-reported) on the relationship between reward sensitivity, and diet using SPSS 25.0. RESULTS: In the main analysis (adolescent-reported), no significant moderation effects were found for parenting practices on the relationship between reward sensitivity and diet. However, the sensitivity analysis (parent-reported) showed a moderation effect for health-reducing parenting practices on the association between reward sensitivity and unhealthy snack intake (ß = 0.297, 95% CI = 0.062, 0.531, p = 0.01). CONCLUSION: Given the difference in the effect of parenting practices between the adolescent- and parent-reported data, our inconclusive findings warrant more research in larger adolescent-parent dyad samples.

RESUMEN

Although it has been proposed that obese and healthy weight individuals might differ in their reward and punishment sensitivity, the literature shows diverse and inconsistent findings. The current study was set out to examine the role of reward and punishment sensitivity in adolescent obesity by differentiating between reward responsivity and reward drive, and by complementing self-report measures with performance-based measures indexing attention for cues signaling reward and punishment as well as effort to approach reward and avoid punishment. Participants were adolescents aged 12-23, with obesity (n = 51, adjusted BMI [(actual BMI/Percentile 50 of BMI for age and gender) × 100) between 143 and 313%], and with a healthy weight (n = 51, adjusted BMI between 75 and 129%). Individuals with obesity did not significantly differ from adolescents with a healthy weight in reward responsivity, reward drive or attention to cues signaling reward. Further, no differences in self-reported punishment sensitivity or attention for cues signaling punishment were found between obese and healthy weight adolescents. The current study thus does not corroborate the theories that general reward and punishment sensitivity play a role in obesity.

RESUMEN

Binge eating among adolescents is associated with negative developmental outcomes. From a cognitive perspective, the role of impaired self-regulation is increasingly emphasized as an underlying factor in binge eating, whereas the affect regulation model proposes that affectivity is a key factor in explaining binge eating. Studies combining both perspectives are scarce, but necessary to add to the understanding of this pathological eating behavior. Therefore, the aim of the current study was to investigate unique and joint contributions of both factors in understanding binge eating among adolescents. Participants were 301 adolescents (10-17 years; 67.2% girls; Mage = 13.46 years; SD = 1.99) from the general community. Adolescents self-reported on different types of binge eating episodes (loss of control over eating in general, objective and subjective binge eating in particular), self-regulation (general self-regulation and inhibitory control) and affectivity (positive and negative). The parents were questioned about their children's self-regulatory capacities. Results revealed main effects of self-regulatory capacities (adolescent report) and negative affectivity in predicting objective binge eating. In addition, negative affectivity interacted with self-regulation (parent report) to predict objective binge eating, whereas positive affectivity interacted with self-regulation (adolescent report) to predict subjective binge eating. No significant effects were found for loss of control over eating specifically. Both self-regulation and affectivity each make unique as well as joint contributions to binge eating among adolescents, with results differing across types of binge eating episodes and informants. Theoretical and practical implications are discussed.

RESUMEN

BACKGROUND: Non-suicidal self-injury (NSSI) is defined as the repetitive, direct, and deliberate destruction of one's body tissue without an intention to die. Existing cross-sectional research indicates that the association between maternal/peer attachment and NSSI is mediated by identity synthesis and confusion. However, longitudinal confirmation of the aforementioned mediation models is necessary as cross-sectional models are known to be biased. Consequently, the aim of the present study was to investigate whether identity formation mediates the association between attachment and NSSI in a longitudinal design. METHODS: Three waves of self-report questionnaires data (1 year apart) were collected on maternal and peer attachment, identity, and NSSI from students of a high school in Belgium (at Time 1: Mean age = 15.0 years, SD = 1.85, range = 11-19 years, 50.6% female). Both cross-lagged (between-person) and parallel process latent growth curve (within-person) mediation analyses were used to test the mediation models. RESULTS: Findings of the cross-lagged analyses indicated unidirectional associations among the study variables, that is, from attachment to identity to NSSI. Parallel process latent growth mediation analyses showed that the association between the slope of maternal attachment and the slope of NSSI was mediated by the slopes of identity synthesis and confusion. Peer attachment models did not fit the data. CONCLUSION: The current work demonstrated that dysfunctional maternal and peer attachment may lead to disturbances in identity formation, which, in turn, may lead to increased NSSI. Additionally, within-person analysis indicated that the growth rate of maternal attachment predicted the growth rate of NSSI through the growth rate of identity synthesis and confusion. The clinical relevance of these findings is discussed.

RESUMEN

The present study examined the factor structure and measurement invariance of the Behavioral Inhibition System/Behavioral Approach System (BIS/BAS) scales parent-report in children and adolescents (N = 1,444, 58% girls) across age (Group 1, 2-5 years; Group 2, 6-9 years; Group 3, 10-13 years; Group 4, 14-18 years old) and gender. The results consistently underscored a four-factor structure, resembling the original factor structure, with one BIS-factor and three BAS-factors. Multigroup confirmatory factor analysis showed full measurement invariance across gender as well as across Group 1 and 2, and Group 2 and 3. Strong measurement invariance was found across Group 3 and 4, Group 1 and 3, and Group 2 and 4. Configural and metric invariance was found across Group 1 and 4. Hence, mean-level BIS/BAS scores can be compared across gender and age although comparison between preschool children (Group 1) and late secondary school children (Group 4) should be done with caution.

RESUMEN

Decreased emotional awareness contributes to the risk of internalizing disorders, such as depression. Although emotional awareness may be especially important during adolescence, a developmental period in which emotional arousal is high and the risk of depression rises dramatically, little research has examined the mechanisms linking emotional awareness to depression. Starting from affect regulation models, the current study proposes emotion regulation (ER) as a key underlying mechanism in the emotional awareness-depression relationship. The current study investigated whether maladaptive and adaptive ER strategies mediate the relationship between emotional awareness and depressive symptoms among youth using a cross-sectional design. Participants were 220 youth (65% girls; [Formula: see text] = 11.87, SD = 1.94) who filled out a set of questionnaires assessing emotional awareness, ER strategies, and depressive symptoms. Results revealed no direct relationship between emotional awareness and depressive symptoms. However, emotional awareness yielded a significant mediation effect through total adaptive ER strategies on higher depressive symptoms. No evidence was found for the mediating role of maladaptive ER strategies in this relationship. The current study provides further support for affect regulation models positing that emotional awareness may be a basic skill that is required for learning adaptive ER skills, and thus call for greater attention to adaptive ER strategies.

RESUMEN

OBJECTIVE: Adolescents' snacking habits are driven by both explicit reflective and implicit hedonic processes. Hedonic pathways and differences in sensitivity to food rewards in addition to reflective determinants should be considered. The present study evaluated the feasibility and impact of a mobile phone-delivered intervention, incorporating explicit reflective and implicit rewarding strategies, on adolescents' snack intake. DESIGN: Adolescents (n 988; mean age 14·9 (sd 0·70) years, 59·4 % boys) completed a non-randomized clustered controlled trial. Adolescents (n 416) in the intervention schools (n 3) were provided with the intervention application for four weeks, while adolescents (n 572) in the control schools (n 3) followed the regular curriculum. Outcomes were differences in healthy snacking ratio and key determinants (awareness, intention, attitude, self-efficacy, habits and knowledge). Process evaluation data were collected via questionnaires and through log data of the app. RESULTS: No significant positive intervention effects on the healthy snack ratio (b=-3·52 (se 1·82), P>0·05) or targeted determinants were observed. Only 268 adolescents started using the app, of whom only fifty-five (20·5 %) still logged in after four weeks. Within the group of users, higher exposure to the app was not significantly associated with positive intervention effects. App satisfaction ratings were low in both high and low user groups. Moderation analyses revealed small positive intervention effects on the healthy snack ratio in high compared with low reward-sensitive boys (b=1·38 (se 0·59), P<0·05). CONCLUSIONS: 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.

RESUMEN

OBJECTIVE: Loss of control over eating is common among adolescents and is associated with negative developmental outcomes. Recent evidence points to impaired self-regulation, and more specifically poor inhibitory control, as a contributing factor to loss of control over eating among adults; however evidence in adolescent samples is limited. Moreover, in line with dual-process models, researchers have recently started to investigate the moderating role of automatic processes in this relationship, but again studies in adolescents are lacking. Therefore, the aim of the current study was to: (1) investigate whether there is an association between poor inhibitory control and loss of control over eating also among adolescents, and (2) explore whether this relationship is moderated by automatic processing. METHOD: A community sample of 124 adolescents (10-17 years; 65.3% girls; Mage = 14 years; SD = 1.90) was divided into a 'Loss of Control Group' (n = 30) and a 'No Loss of Control Group' (n = 94) based on a clinical interview. Inhibitory control and automatic processing (general and food specific) were measured by self-report questionnaires. RESULTS: Adolescents in the Loss of Control Group reported significantly more problems with overall self-regulation compared to the No Loss of Control Group; however, there was no group difference for inhibition specifically. Contrary to dual-process predictions, there was a trend significant interaction between poor inhibitory control and weaker food specific automatic processing in explaining loss of control over eating. CONCLUSIONS: Evidence was found for problems with overall self-regulation in adolescents with loss of control over eating. Concerning the specific role of inhibitory control, future studies should replicate whether automatic processing is indeed a crucial moderator.
