Orthorexia nervosa is an emerging and controversial eating disorder characterized by an obsessive preoccupation with healthy eating and an extreme fixation on food purity. Despite growing public interest in orthorexia, its classification as a distinct eating disorder remains a subject of ongoing debate in the mental health community. This paper comprehensively reviews the current literature on orthorexia nervosa, exploring the prevalence rates, risk factors, diagnosis, and treatment options. The paper offers an overview of orthorexia and its historical context and explores the challenges and considerations in diagnosing orthorexia and orthorexia nervosa. Specifically, the distinction between “orthorexia” and “orthorexia nervosa” is a debated issue in eating disorder research due to a lack of clear diagnostic criteria, making it challenging to accurately differentiate between an obsession with healthy eating and a more severe form with potential distress and impairment. Given the absence of formal diagnostic criteria, developing valid and reliable assessment tools is crucial to accurately identify and treat individuals experiencing these disorders. The paper’s final section covers the existing treatment approaches for orthorexia nervosa. Overall, the paper highlights the complex and multifaceted nature of orthorexia nervosa. This review contributes to the ongoing discourse surrounding orthorexia and provides valuable insights for clinicians, researchers, and stakeholders in the mental health and eating disorders fields.

The psychometric properties of a Greek version of the Multidimensional Body-Self Relations Questionnaire–Appearance Scales (MBSRQ–AS) were studied. A total of 1,312 high school students (463 boys, 849 girls) were administered the Greek MBSRQ–AS, the Greek Appearance Schemas Inventory–Revised (ASI–R) and the Greek Sociocultural Attitudes Towards Appearance Questionnaire–3 (SATAQ–3). An exploratory factor analysis revealed that the Greek MBSRQ–AS items significantly loaded with the scale's main factors. Internal consistencies of the subscales ranged from .76 to .86. Test-retest reliabilities ranged from .75 to .93. Convergent validity was also confirmed as the Greek MBSRQ–AS subscales correlated positively with the ASI–R and the SATAQ–3.

The primary focus of this review is to rigorously explore the application and significance of coping strategies within the domains of clinical psychology and neuropsychology. These consist of a variety of techniques, behaviors, and cognitive interventions, and their critical role in reinforcing resilience and facilitating adaptive responses to stressors has been highlighted. This study explores the complex neuropsychological links between the brain’s stress pathways and the use of coping mechanisms. The neural aspects of stress, and how they can be influenced by adaptive strategies, are detailed, illustrating the profound impact that these coping mechanisms have at a neurobiological level. Delving into the neuropsychological underpinnings, this review will shed light on how stress response pathways in the brain interact with, and can be modulated by, various coping strategies. These mechanisms are particularly salient when addressing the multifaceted challenges that are faced by individuals with neuropsychological or mental health issues. While these strategies span a broad spectrum, from introspection and cognitive reframing to behavioral activation and social support seeking, their integration and application remain diverse within clinical contexts. This review endeavors to elucidate the theoretical underpinnings of these strategies, their empirical support, and their practical implications within therapeutic interventions. Furthermore, the intricate interplay between individualized coping techniques and structured therapeutic methodologies will be examined, emphasizing the potential for a holistic treatment paradigm, thereby enhancing therapeutic outcomes and fostering individual resilience.

The Satisfaction With Life Scale (SWLS) is a widely used self-report measure of subjective well-being, but studies of its measurement invariance across a large number of nations remain limited. Here, we utilised the Body Image in Nature (BINS) dataset–with data collected between 2020 and 2022 –to assess measurement invariance of the SWLS across 65 nations, 40 languages, gender identities, and age groups (N = 56,968). All participants completed the SWLS under largely uniform conditions. Multi-group confirmatory factor analysis indicated that configural and metric invariance was upheld across all nations, languages, gender identities, and age groups, suggesting that the unidimensional SWLS model has universal applicability. Full scalar invariance was achieved across gender identities and age groups. Based on alignment optimisation methods, partial scalar invariance was achieved across all but three national groups and across all languages represented in the BINS. There were large differences in latent SWLS means across nations and languages, but negligible-to-small differences across gender identities and age groups. Across nations, greater life satisfaction was significantly associated with greater financial security and being in a committed relationship or married. The results of this study suggest that the SWLS largely assesses a common unidimensional construct of life satisfaction irrespective of respondent characteristics (i.e., national group, gender identities, and age group) or survey presentation (i.e., survey language). This has important implications for the assessment of life satisfaction across nations and provides information that will be useful for practitioners aiming to promote subjective well-being internationally.

The current study aimed to identify potential psychosocial risk and protective factors contributing to eating disorders in adolescents, and observe any differences between genders and Body Mass Index (BMI) categories. A cross-sectional survey was carried out with a total of 2605 (1063 male) adolescents, who were assessed for disordered eating, body-image satisfaction and investment, appearance/weight-related anxiety, situational dysphoria, media influences, self-esteem, and body appreciation. The results revealed that weight/appearance-related anxiety and situational dysphoria were the most significant risk factors for both genders. Pressures from the media posed a significant risk only for males and the internalization of the thin ideal only for females; however, the internalization of the athletic ideal did not pose as a significant risk factor. Compared to gender, these risk factors did not differ based on BMI. Additionally, body appreciation was found to be a robust protective factor (unlike global self-esteem) for both genders, and across all BMI groups. The findings indicate that the most significant risk and protective factors of eating disorders do not differ largely for male and female adolescents or different BMIs. Intervention and prevention programs would therefore benefit from the inclusion of exercises that reduce the constructs of weight/appearance-related anxiety and situational dysphoria, and promote body appreciation.
