ABSTRACT
Response inhibition difficulties are reported in individuals with eating disorders (EDs), anxiety, and depression. Although ED symptoms and internalizing symptoms co-occur in preadolescence, there is limited research examining associations between these symptoms and response inhibition in this age group. This study is the first to investigate the associations between behavioral and neural markers of response inhibition, disordered eating (DE), and internalizing symptoms in a community sample of preadolescents. Forty-eight children (M age = 10.95 years, 56.3% male) completed a Go/NoGo task, whereas electroencephalography was recorded. Self-report measures of DE and internalizing symptoms were collected. Higher levels of anxiety and depression were associated with neural markers of suboptimal response inhibition (attenuated P3NoGo amplitudes) in preadolescence. In contrast, higher levels of depression were associated with greater response inhibition at a behavioral level. These findings suggest internalizing symptoms in preadolescence are associated with P3-indexed difficulties in evaluation and monitoring, but these are not sufficient to disrupt behavioral performance on a response inhibition task. This pattern may reflect engagement of compensatory processes to support task performance. DE was not significantly associated with response inhibition, suggesting that difficulties in response inhibition may only be reliably observed in more chronic and severe DE and ED presentations.

Anorexia nervosa (AN) and obsessive-compulsive disorder (OCD) are commonly reported to co-occur and present with overlapping symptomatology. Executive functioning difficulties have been implicated in both mental health conditions. However, studies directly comparing these functions in AN and OCD are extremely limited. This review provides a synthesis of behavioral and neuroimaging research examining executive functioning in AN and OCD to bridge this gap in knowledge. We outline the similarities and differences in behavioral and neuroimaging findings between AN and OCD, focusing on set shifting, working memory, response inhibition, and response monitoring. This review aims to facilitate understanding of transdiagnostic correlates of executive functioning and highlights important considerations for future research. We also discuss the importance of examining both behavioral and neural markers when studying transdiagnostic correlates of executive functions.
ABSTRACT
Objective: According to self-determination theory, satisfied basic psychological needs can be a protective factor for psychopathology, including eating disorders and anxiety symptomatology. However, most research has focused on adolescent and adult populations, with less work examining perceived basic psychological need satisfaction from parents in younger samples who report anxiety and disordered eating. This cross-sectional study aimed to investigate whether basic psychological need satisfaction from parents was associated with disordered eating in preadolescents and whether anxiety mediated this relation.Method: A total of 211 preadolescents were recruited from primary schools across south Wales (mean age = 10.27 years, age range = 9-11 years; 49.3% female). Children completed self-report questionnaires on their basic psychological need satisfaction when with parents, as well as disordered eating and anxiety symptoms.Results: It was found that higher needs satisfaction was associated with lower disordered eating and anxiety, with stronger relations found in girls compared with boys. Furthermore, anxiety was found to mediate this relationship.Conclusions: Results suggest that basic psychological needs satisfaction may play an important role in the early emergence of co-occurring disordered eating and anxiety symptoms in boys and girls. The importance of considering anxiety symptoms in future work investigating needs satisfaction in the context of disordered eating and eating disorders is discussed.
ABSTRACT
OBJECTIVES: Research has demonstrated links between disordered eating, anxiety, and depression in adults and adolescents but there is limited research investigating these associations in preadolescence. The current study examined the associations between disordered eating, anxiety, and depression during preadolescence, as well as the role of gender in moderating these associations. METHOD: Two hundred and thirteen children (M = 10.3 years; 51.2% male) reported levels of disordered eating (ChEAT) and anxiety and depression symptoms (RCADS-25). RESULTS: Regression analyses support an association between disordered eating and both anxiety and depression in preadolescence. Overall, there were no significant differences between boys and girls when the main effect was examined, which differs from research in adolescents. DISCUSSION: These findings highlight the importance of early detection for disordered eating behaviors and attitudes, as well as anxiety and depression in both boys and girls during preadolescence. Longitudinal research examining these associations is vital to help understand the trajectories of these problems, but also the gender differences in disordered eating that emerge during adolescence. Transdiagnostic interventions targeting several co-occurring problems, such as disordered eating, anxiety, and depression might be effective for preventing the development of eating disorders in the long term.
