This cross-sectional study aims to shed further light on the relation between self-esteem and Eating Disorders (EDs) as part of prevention efforts by testing the mediating role of psychological inflexibility in a sample of young teenagers. Four hundred and eighteen Greek-speaking students from one representative public middle school in Cyprus (43.90% males and 56.10% females; Mage = 13.71, SD = 1.00) were screened for ED pathology using the Eating Attitudes Questionnaire-26 (EAT-26) and completed the Rosenberg Self-Esteem Scale (RSE) and the Avoidance and Fusion Questionnaire for Youth (AFQ-Y8). Screening was part of a school-wide psychoeducational Campaign titled “Love Your Body-Young Teens”, which aimed to raise awareness on healthy body image and EDs within the school community. Correlations and bootstrapping mediation analyses were conducted to evaluate the relations between ED pathology, self-esteem, and psychological inflexibility. Mediation analyses results showed that psychological inflexibility partly mediates the relationship between self-esteem and ED pathology. These preliminary findings highlight the contributions of both the individual’s negative internal events and their meta-response to these events in the development of EDs. It lays the foundation for the delivery of research-informed psychological prevention efforts in the schools, aiming to increase psychological flexibility among students.

Objectives: Congenital heart disease (CHD) is a prevalent condition affecting young people that often necessitates complex medical interventions. This study aims to provide a synthesis of existing meta-analyses examining the impact of CHD on the cognitive functioning in children and young people; Methods: A comprehensive literature review was conducted, identifying peer-reviewed meta-analyses from 1 January 1976 to 17 December 2024, focusing on the cognitive outcomes of CHD patients aged 0–24 years. Data extraction covered study details, participant demographics, outcomes, and quality assessments. Quality assessment followed the Scottish Intercollegiate Guidelines Network (SIGN) checklist, and a narrative synthesis was conducted; Results: The narrative synthesis highlighted significant cognitive impairments in children with CHD across domains such as Intelligence Quotient (IQ), executive functions (EF), memory, and alertness. Cognitive impairments were also observed to become worse with increasing age. Furthermore, surgical interventions were found to impact cognitive outcomes, with surgeries at an early age improving survival rates but not entirely mitigating cognitive deficits. Cognitive impairments were more marked in young people assessed at an older age and with a more complex CHD presentation. Conclusions: Children with CHD face persistent cognitive challenges, underscoring the need for early identification and tailored interventions. Routine cognitive assessments and comprehensive care, including educational and psychological support, are crucial for improving neurodevelopmental outcomes. Future research should focus on longitudinal studies to track cognitive development and explore effective rehabilitation programs.

Background/Objectives: Appearance ideals are increasingly transmitted through digital media, reshaping the sociocultural context in which disordered eating develops. Central and Eastern European populations remain underrepresented in this literature. This study examined the prevalence of disordered eating attitudes in a Hungarian adult community sample and tested an integrated model of body image disturbance and media-transmitted sociocultural pressures as statistical predictors, including formal tests of mediation. Methods: Hungarian adults (N = 675; 70.8% female; aged 16–81 years, M = 44.09) completed the Eating Attitudes Test–26 (EAT-26), the Body Attitude Test (BAT), and the Sociocultural Attitudes Towards Appearance Questionnaire–3 (SATAQ-3) in an online survey; body mass index (BMI) was calculated from self-reported height and weight. All instruments demonstrated good to excellent internal consistency in the present sample (Cronbach’s α = 0.84–0.93). Results: One in five participants (20.7%) scored at or above the EAT-26 clinical cut-off, with elevated rates at both extremes of the BMI spectrum (underweight: 30.0%; obese: 28.4%). Women scored higher than men on the EAT-26 (d = −0.59), BAT (d = −0.80), and three SATAQ-3 subscales; no gender difference emerged for athletic-ideal internalisation (d = −0.02), consistent with a cross-gender athletic ideal. The predictor set accounted for 40.5% of the variance in EAT-26 scores; BAT was the dominant predictor (β = 0.61), while SATAQ-3 Athletic retained a direct path (β = 0.08), and the remaining media-influence subscales lost significance once body image was controlled. A binary logistic regression using these predictors correctly classified 83.6% of participants (Nagelkerke R2 = 0.35), with BAT and athletic-ideal internalisation again the only significant predictors of clinical-range classification. Bootstrapped mediation analyses confirmed that the associations between sociocultural influences and disordered eating attitudes were largely mediated by body image disturbance; only athletic-ideal internalisation retained a significant direct association (partial mediation). Conclusions: Body image disturbance constitutes the proximal core of disordered eating attitudes, whereas internalisation of the athletic ideal shows a small independent association, with implications for screening and prevention across the adult lifespan.
