The dimensional Yale Food Addiction Scale for Children 2.0 (dYFAS-C 2.0) was developed to provide a reliable psychometric measure for assessing food addiction in adolescents, in accordance with the updated addiction criteria proposed in the fifth edition of the Diagnostic and Statistical Manual (DSM-5). The present study aimed to evaluate the psychometric properties of the dYFAS-C 2.0 among Portuguese adolescents and pre-adolescents and to explore the relationship between food addiction and other eating behaviors such as grazing and intuitive eating. The participants were 131 Portuguese adolescents and pre-adolescents (53.4% female and 46.6% male) aged between 10 and 15 years (Mage = 11.8) and with a BMI between 11.3 and 35.3 (MBMI z-score = 0.42). Confirmatory Factor Analysis demonstrated an adequate fit for the original one-factor model (χ2 (104) = 182; p < 0.001; CFI = 0.97; TLI = 0.97; NFI = 0.94; SRMR = 0.101; RMSEA = 0.074; 95% CI [0.056; 0.091]). Food addiction was positively correlated with higher grazing (r = 0.69, p < 0.001) and negatively correlated with lower reliance on hunger/satiety cues (r = −0.22, p = 0.015). No significant association was found between food addiction and BMI z-score, or between food addiction and age. The results support the use of dYFAS-C 2.0 as a valid and reliable measure for assessing food addiction in Portuguese adolescents and pre-adolescents. Furthermore, the findings highlight that food addiction may be part of a spectrum of disordered eating behaviors associated with control impairment. Future research with a larger sample size could further elucidate the associations between food addiction and other variables, such as psychological distress and multi-impulsive spectrum behaviors.

University students are a vulnerable population to the development of disordered eating, such as food addiction (FA) and grazing. FA is an emerging concept characterized by an intense desire to eat hyper-palatable foods. Grazing is characterized by the repetitive and unplanned ingestion of food throughout a period of time. Both FA and grazing have been associated with increased scores of negative urgency (NU) and difficulties in emotion regulation (ER). This study aims to evaluate the frequency of FA and grazing in a university population and to test the direct, total, and indirect effects—via FA—of ER and NU on repetitive eating and compulsive grazing. A total of 338 participants responded to a set of psychological measures assessing these variables. Thirty-six (10.7%) participants met the criteria for FA diagnosis and 184 (54.4%) presented grazing. Confirmatory factor analysis showed acceptable fit indexes for the model tested (χ2(1695) = 3167.575; p < 0.001; CFI = 0.955; NFI = 0.908; TLI = 0.953; SRMR = 0.085; RMSEA = 0.051; CI 90% (0.048; 0.053); P[RMSEA ≤ 0.05] = 0.318) and suggested that FA partially mediated the effect of difficulties in ER and NU on grazing, specifically on compulsive grazing. The results indicate that individuals with difficulties in ER and impulse control under negative emotions are more likely to engage in grazing if food addiction scores are higher. These results highlight the importance of assessing these variables, particularly in at-risk populations such as university students. [ABSTRACT FROM AUTHOR]

Overview: In recent years, there has been increasing clinical and empirical interest in the concept of pediatric loss of control over eating, particularly about its link with the executive functions related to the concept of impulsivity, such as inhibitory control and reward sensitivity. However, there has yet to be a comprehensive literature synthesis about the associations between these variables. A comprehensive literature synthesis would help identify future research directions to advance the field in this area. Therefore, this systematic review aimed to synthesize evidence concerning the associations between loss of control over eating, inhibitory control, and reward sensitivity in children and adolescents. Methods: The systematic review was conducted according to the guidelines proposed by PRISMA in Web of Science, Scopus, PubMed, and PsycINFO. The Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies was used to assess the risk of bias. Results: Twelve studies met the selection criteria and were included in the final review. Overall, methodological heterogeneity, variability in assessment methods, and the age of participants make it difficult to draw general conclusions. Nevertheless, most studies with community samples of adolescents indicate that inhibitory control difficulties are linked to the concept of loss of control eating. The presence of obesity seems to be associated with inhibitory control difficulties, regardless of the presence of loss of control eating. Studies on reward sensitivity are scarcer. However, it has been suggested that higher reward sensitivity is related to loss of control eating behaviors in young people, particularly binge eating. Conclusions: The literature on the link between loss of control eating and trait-level facets of impulsivity (low inhibitory control and higher reward sensitivity) among young people remains limited, and more studies on children are needed. Findings from this review may make healthcare professionals more aware of the potential clinical importance of targeting the trait-level facets of impulsivity and help to inform existing and future weight-loss/maintenance interventions in childhood and adolescence.

Physical appearance comparisons have been theorized to be associated with negative indicators of body image. This study aimed to study appearance comparisons and their association to affect, body dissatisfaction, and eating pathology. Three hundred and ten female university students with ages between 17 and 25 years (M = 20.2, SD = 1.9) completed sociodemographic and clinical data, self-reported questionnaires, and questions about appearance comparisons. Among the participants, 98.71% reported making appearance comparisons, and 42.15% of these reported making them frequently or always. Higher reported frequencies of appearance comparisons were related to higher levels of body dissatisfaction, negative affect, and eating pathology. Appearance comparisons to acquaintances were the most frequent. Comparisons in person and through media were reported in similar proportions. Upward comparisons were more frequent than lateral and downward comparisons and were related to higher levels of body dissatisfaction than downward comparisons and to higher levels of body dissatisfaction, negative affect, and eating pathology than lateral comparisons. Upward comparisons to close peers were associated with higher body dissatisfaction as opposed to models/celebrities. Results, limitations, and implications are discussed. [ABSTRACT FROM AUTHOR]

This study sought to determine the frequency of possible cases of avoidant/restrictive food intake disorder (ARFID) in a Portuguese sample of school-aged children and to assess the associations with child's internalizing problems, BMI z-score and body dissatisfaction, and parents' eating habits, attitudes and practices. We assessed 330 children through child's and parents'measures. Fifty-one (15.5%) children were possible cases of ARFID based on their symptom's presentation. There were no association between sex and possible cases of ARFID, and no significant differences between possible cases of ARFID and nonpossible cases of ARFID regarding age. Lower BMI z-score and anxiety/depression were associated with possible cases of ARFID. [ABSTRACT FROM AUTHOR]

Background Bulimia nervosa ( BN) is often related to self-control difficulties and to dysregulated behaviours. This study aimed to evaluate the frequency of self-injurious behaviour, suicide attempts, and other dysregulated behaviours in BN, using two control groups (a healthy group and a general psychiatric group), and also to examine the association between these behaviours and alleged sexual abuse in BN. Method Women ( N = 233) aged between 13 and 38 years old were evaluated using a semi-structured interview. Results Participants with BN reported more self-injurious behaviours, suicide attempts by drug intake, and poor control in smoking and illicit drugs use compared with participants in both control groups. Participants with BN also reported more spending behaviours when compared with the general psychiatric control group. The use of illegal drugs and medication was significantly related to alleged sexual abuse in BN participants. Conclusions This study concluded that BN is often related to dysregulated behaviours, and clinicians must take into account the multi-impulsive spectrum behaviours of BN in their evaluation and treatment of BN.

This study tested societal effects on caregiver/teacher ratings of behavioral/emotional problems for 10,521 preschoolers from 15 societies. Many societies had problem scale scores within a relatively narrow range, despite differences in language, culture, and other characteristics. The small age and gender effects were quite similar across societies. The rank orders of mean item ratings were similar across diverse societies. For 7,380 children from 13 societies, ratings were also obtained from a parent. In all 13 societies, mean Total Problems scores derived from parent ratings were significantly higher than mean Total Problems scores derived from caregiver/teacher ratings, although the size of the difference varied somewhat across societies. Mean cross-informant agreement for problem scale scores varied across societies. Societies were very similar with respect to which problem items, on average, received high versus low ratings from parents and caregivers/teachers. Within every society, cross-informant agreement for item ratings varied widely across children. In most respects, results were quite similar across 15 very diverse societies. [ABSTRACT FROM AUTHOR]

Caregivers and teachers from 14 societies rated 9,389 1.5 to 5-year-olds on the Caregiver-Teacher Report Form (C-TRF; Achenbach & Rescorla, 2000). General population samples were obtained in Asia; the Middle East; Eastern, Northern, Central, Western, and Southern Europe; and South America. The 2-level 6-syndrome C-TRF model derived on a mostly U.S. sample was tested separately for each society. This model or a slightly modified 2-level 5-syndrome version of the model fit the data for 10 of the 14 societies. The findings generally support use of the C-TRF with children of diverse backgrounds. The multicultural generalizability of C-TRF syndromes suggests that they can be used as taxonomic constructs for preschoolers' psychopathology, which can facilitate international communication and collaboration between clinicians, researchers, and educators working with young children.
