Eating disorder symptom dimensions and protective factors: A structural network analysis study

Eating Disorders (EDs) and related symptoms pose a substantial public health concern due to their widespread prevalence among both genders and associated negative outcomes, underscoring the need for effective preventive interventions. In this context, deepening our understanding of the interplay between ED symptoms and related protective factors appears crucial. Therefore, this study employed a structural network analysis approach considering both ED symptom dimensions (i.e., drive for thinness, bulimic symptoms, and body dissatisfaction) and related protective factors (i.e., body and functionality appreciation, intuitive eating, and self-esteem) to shed light on how these factors are interrelated. A community sample of 1391 individuals (34.4% men; Mage = 26.4 years) completed a socio-demographic schedule and self-report questionnaires. The network showed that the nodes with the highest positive expected influence were body and functionality appreciation, while those with the highest negative expected influence were eating for physical rather than emotional reasons and unconditional permission to eat (i.e., two components of intuitive eating). Crucially, the most relevant bridges between the conceptual communities "ED symptom dimensions" and "Protective factors" were the negative relations between (a) eating for physical rather than emotional reasons and bulimic symptoms, (b) unconditional permission to eat and drive for thinness, and (c) body appreciation and body dissatisfaction. Finally, age, gender, and body mass index did not moderate any edge in the network. The practical implications of these findings are discussed, especially in terms of preventive interventions for ED symptoms.

"Can I Have More Than This?" The Role of Romantic Relationship Quality, Maximization Style, and Social Media Addiction in Relationship Obsessive Compulsive Disorder Symptoms

Relationship Obsessive Compulsive Disorder (ROCD) is a form of obsessive-compulsive disorder that manifests in the relationship domain, such as romantic relationships. Within romantic relationship, ROCD symptoms could be focused on flaws perceived on the relationship itself (ROCD relationship-centered) or on the partners' quality (ROCD partner-focused). These symptoms are associated with negative relationship outcomes, such as low relationship satisfaction. However, no studies have yet addressed the role of relationship quality in the context of ROCD. Furthermore, previous studies have shown the detrimental role of social media use and maximization style in obsessive-compulsive symptoms and the romantic relational domain; however, the associations with ROCD symptoms have not yet been explored. Thus, this study aimed to close this gap examining the associations between ROCD symptoms (relationship-centered and partner-focused) and relationship quality, social media addiction, and maximization style. A total of 211 participants currently involved in a romantic relationship (71.1 percent female, mean age = 30.4 ± 11.54 years) participated in the study. Multiple hierarchical regression analyses revealed that relationship quality, social media addiction, and maximization style emerged as being significantly associated with relationship-centered and partner-focused ROCD symptoms. The results highlighted potential risk factors for ROCD symptoms in romantic relationships, namely relationship quality, social media addiction, and maximization style. These psychological dimensions could be identified as possible targets in the assessment and treatment of ROCD symptoms.

Psychometric properties of an Italian translation of the Functionality Appreciation Scale (FAS)

The Functionality Appreciation Scale (FAS; Alleva et al., 2017) is a widely used instrument for the measurement of individual's appreciation of their body for what it can do and is capable of doing (i.e., functionality appreciation). Here, we examined the psychometric properties of a novel Italian translation of the FAS. A sample of 950 Italian adults completed the FAS, as well as previously validated measures of body image (body appreciation, body esteem, body surveillance), disordered eating symptoms, and psychological well-being (self-esteem, general distress). Exploratory and confirmatory factor analyses supported a 1-dimensional model of FAS scores, with all 7 items retained. Scores achieved scalar invariance across gender, and the gender difference in latent FAS scores was not significant. FAS scores were found to have adequate internal consistency, test-retest reliability up to three weeks, and convergent and criterion-related validity through significant correlations with all additional constructs. However, evidence of incremental validity was weak, and likely reflected high nomological and conceptual similarity between functionality and body appreciation in this national context. Overall, these results provide strong evidence that scores on the Italian FAS are psychometrically valid, which may aid future development of interventions to promote more positive body image in Italian-speaking samples.
