The Relationship between Executive Functions and Body Weight: Sex as a Moderating Variable.

This study explores the interplay between executive functions and body weight, examining both the influence of biological factors, specifically sex, and methodological issues, such as the choice between Body Mass Index (BMI) and waist circumference (WC) as the primary anthropometric measure. A total of 386 participants (222 females, mean age = 45.98 years, SD = 17.70) were enrolled, from whom sociodemographic (sex, age, years of formal education) and anthropometric (BMI and WC) data were collected. Executive functions were evaluated using the Frontal Assessment Battery-15 (FAB15). The results showed the increased effectiveness of WC over BMI in examining the relationships between executive functions, sex differences, and body weight. In particular, this study revealed that there was a significant moderating effect of sex at comparable levels of executive functioning. Specifically, women with higher executive performance had lower WCs than their male counterparts, suggesting that executive function has a greater impact on WC in women than in men. Our findings highlight the importance of conducting more in-depth investigations of the complex relationship between cognitive deficits and weight gain, considering confounding variables of behavioral, psychobiological, and neurophysiological origin.

Functional Characteristics and Coping Strategies among Rugby Athletes: A Cluster Analysis Approach.

The developing domain of mental health in sports has gained much interest, acknowledging its pivotal role in athlete performance and well-being. The aim of this research is to provide a quantitative description concerning the levels of mental health, physical activity, cognitive fusion, cognitive flexibility, and coping strategies that characterize rugby athletes by using a data-driven approach. A total of 92 rugby athletes took part in this study and filled out a set of self-administered questionnaires. A correlational analysis showed that general well-being was positively associated with years spent playing rugby (r = 0.23) and coping mechanisms (r = 0.29). Athletes' well-being was also negatively correlated with cognitive inflexibility (r = -0.41) and cognitive fusion (r = -0.39). A k-means cluster analysis identified two unique groups: group 1, characterized by higher levels of psychological well-being, lower levels of physical activity, greater cognitive flexibility, improved coping techniques, and reduced cognitive fusion, and group 2, which exhibits opposite characteristics. The discrepancies observed in psychological characteristics such as coping strategies, cognitive fusion, and cognitive inflexibility highlight their potential impact on the general health of rugby players. To comprehend the complex interplay between psychological and physical elements in rugby athletes, long-term studies with larger samples are crucial.

Anorexia Nervosa and Autism Spectrum Disorder: A Systematic Review.

BACKGROUND: Recent research has shown a growing interest in exploring the relationship between anorexia nervosa (AN) and autism spectrum disorder (ASD). Both conditions seem to share areas of cognitive, social and behavioural impairment, leading to relevant implications on treatment, especially when they are in comorbidity. This literature review aims to synthesise the latest studies on this topic to investigate the co-occurrence of AN and ASD, suggest future research directions and consider implications for treatment. METHOD: Records were systematically (PRISMA guidelines) identified through PubMed, EBSCOhost, Scopus and Web of Science searching. RESULTS: Thirteen studies met the eligibility criteria and were therefore included in the review. Results seem to confirm an overrepresentation of ASD symptoms in AN. Only few studies investigated the AN-ASD comorbidity in young people and report slightly lower rates than those conducted with adults. CONCLUSIONS: Analysed studies suggest that while the comorbidity seems to exacerbate the severity of the condition, autistic traits appear to be rather stable over time and not related to body weight. Thus, future longitudinal studies and gender- specific assessment tools can help clarify the relationship between the two disorders, examine the onset of ASD symptoms and develop structured guidelines for treatment.

Effects of Pet Therapy in Elderly Patients with Neurocognitive Disorders: A Brief Review.

INTRODUCTION: Neurocognitive disorders (NCDs) are disturbances highly related to age. This means that, with the increasing trend in life expectancy, there is also an increase in this diagnosis, although NCDs are not exclusively found in the population over 65 years old. Likely, they will increase in the coming years together with improvements in diagnosis. In addition to the use of medicines and rehabilitative techniques, pet therapy is also used. Pet therapy makes use of animals with therapeutic, rehabilitative, educational, and recreational purposes for people affected by physical, neuromotor, and psychiatric disorders. Pet therapy seems to be functional for increasing social and communication competencies, facilitating verbal and body language, increasing self-esteem, improving quality of life, and reducing anxiety/stress. METHODS: This study was based on scientific papers and publications obtained from the PubMed and Google Scholar databases. Moreover, other articles from further cross-references were included. Specific database research criteria were (a) articles published in 2018 or later, (b) samples containing only adults over 65 years old, (c) written in English or Italian, and (d) on the topic of animal-assisted intervention. RESULTS: Uncertain results were obtained. Although a positive effect was found, the included articles were of insufficient methodological rigor. DISCUSSION/CONCLUSION: Although many studies reported positive results, these could not be generalized because of the numerous biases present (e.g., small sample size, lack of methodological rigor, lack of protocol, etc.). Future studies, therefore, should seek to address the limitations found in the analyzed studies.

Repetitive Negative Thinking and Eating Disorders: A Meta-Analysis of the Role of Worry and Rumination.

The role of worry and rumination in eating disorders (EDs) is controversial. This meta-analysis of the literature is aimed at clarifying the relationship between repetitive negative thinking (RNT) and EDs. In accordance with the PRISMA criteria, a comprehensive search of the literature was conducted on PubMed and PsycInfo from inception to March 2021. Search terms: "eating disorder/anorexia/bulimia/binge eating disorder" AND "worry/rumination/brooding/repetitive thinking". A manual search of reference lists was also run. Forty-three studies were included. RNT was found to be associated with anorexia, bulimia, and binge eating disorder. A moderating effect was found for "presence/absence ED diagnosis" and "subtype of ED symptom". ED patients showed higher RNT than the general population. No differences were observed for age or between worry and rumination in the magnitude of their association with EDs.

The Body of Cognitive and Metacognitive Variables in Eating Disorders: Need of Control, Negative Beliefs about Worry Uncontrollability and Danger, Perfectionism, Self-esteem and Worry.

BACKGROUND: Many studies have described perfectionism and low self-esteem as traits associated with eating disorders (ED). More recently, research has shown the role played by worry, rumination, control and metacognitive beliefs. This paper investigates the role played by cognitive and metacognitive variables in the psychopathological mechanism of eating disorders, assuming that not only perfectionism and low selfesteem but also metacognitive beliefs and processes can discriminate between controls and EDs. METHOD: The Structured Clinical Interview for DSM, the Multidimensional Perfectionism Scale, the Rosenberg Self-Esteem Scale, the Anxiety Control Questionnaire, the Penn State Worry and the Metacognition Questionnaire were administered to the samples. RESULTS: Results suggested that metacognitive factors like negative beliefs about worry, uncontrollability and danger, need for control, and worry should be added to the body of cognitive factors underlying ED composed by the classical couple of cognitive factors including perfectionism and low self-esteem. CONCLUSIONS: It is possible that an individual with ED assumes that metacognitive processes like worry and rumination are a further proof of his or her lack of value, capacity to control, and self-control. Such appraisals may reinforce the painful sense of low self-esteem so typical in ED and, in turn, the perfectionistic striving for excellence.
