The Borderline–Narcissistic Relational Pattern (BNRP): A Theoretical Framework and Proposal for a Relational Measure
No full textProject Update (Version 2): Theoretical Expansion
This project now includes an expanded theoretical formulation titled The BNRP–Regulatory Model (BNRP–RM). While the original BNRP framework described observable dyadic interaction patterns and introduced the BNRP Scale (BNRPS), the revised model advances the theory by conceptualizing the pattern as a failure of mutual affect regulation within a dyadic system. The updated version introduces the constructs of opposing regulatory strategies (hyperactivation vs. deactivation), mutual identity threat, cultural modulation of relational distress, and reenactment processes in psychotherapy. This shift represents a move from a primarily descriptive relational model to a deeper regulatory and identity-based explanatory framework
Efficacy and Safety of Ustekinumab for Pediatric and Adult Crohn's Disease: An Umbrella Review of Systematic Reviews and Meta-Analyses
No full textUstekinumab is an established biologic therapy for Crohn’s disease (CD). While numerous systematic reviews (SRs) and meta-analyses (MAs) have synthesized evidence on its use, these reviews vary in scope, methodology, and conclusions, particularly when comparing pediatric and adult populations. An umbrella review is needed to comprehensively map, critically appraise, and synthesize this high-level evidence
Mapping the Landscape of Green Human Resource Management (GHRM): A Bibliometric Approach
No full textThis study employs a bibliometric approach to systematically map the intellectual structure and research evolution of Green Human Resource Management (GHRM), addressing the absence of comprehensive quantitative reviews in the field. Using bibliographic data retrieved from the Web of Science database covering the period 2015–2024, the analysis applies citation analysis, co-authorship networks, keyword co-occurrence, and bibliographic coupling techniques through VOSviewer and Biblioshiny. Focusing on the Asian context, the study examines 198 peer-reviewed articles to identify dominant research themes, influential authors, leading journals, and regional collaboration patterns. The findings reveal a sharp growth in GHRM research, with sustainability, environmental performance, green supply chain management, and employee green behavior emerging as central themes. China, Pakistan, and Malaysia are identified as major contributors to regional scholarship. By consolidating existing knowledge and highlighting emerging trends, this study advances understanding of GHRM as a strategic component of sustainable business practices and proposes a forward-looking research agenda emphasizing interdisciplinary integration, global inclusivity, and alignment with ESG and corporate social responsibility frameworks

Food and Alcohol Disturbance
Food and Alcohol Disturbance (FAD, also known as drunkorexia) refers to the engagement in compensatory behaviors (restricting eating and/or purging) before, during, and/or after alcohol consumption to offset calories consumed from alcohol and/or to enhance alcohol intoxication (Choquette et al., 2018b). FAD represents a functional relationship between disordered eating and alcohol use behaviors, rather than just their co-occurrence, which makes FAD unique (Berry et al., 2024). FAD is not considered as a subtype of an alcohol or eating disorder. In co-morbid presentations, alcohol use and disordered eating behaviors can co-exist independently for distinct purposes. These key differences highlight the importance of FAD as its own entity and a distinct phenomenon. Previous studies have reported a relatively high prevalence of FAD behaviors in university students, affecting up to 55% of them (Choquette et al., 2018a; Knight et al., 2017; Moeck and Thomas, 2021; Palermo et al., 2021; Peralta et al., 2019; Pietrabissa et al., 2018; Pinna et al., 2024). This highlights that FAD behaviors are not uncommon. Accordingly, numerous quantitative correlational studies have examined the predictors of FAD among adolescents and university students (for review see Berry et al., 2024; Shepherd et al., 2021) with the aim of identifying the behavioral dimensions associated with these behaviors.
Psychosociale correlates of FAD behaviors
Two distinct motivations have been identified as underlying FAD: to enhance the intoxicating effects of alcohol and/or to compensate for alcohol-related caloric intake (Choquette et al., 2018b). The alcohol enhancement motive seems to be reported with relatively equal frequency to the caloric compensation motive, ranging from 23.7% to 35.8% and from 37.6% to 49.3% for respectively, among university students (for a review see Berry et al., 2024). Alcohol use (including alcohol quantity and frequency, binge drinking episodes, episodes of drunkenness, and drinking motives) and disordered eating behaviors (such as dietary restraint, eating disorder symptomatology, purging behaviors, and dysfunctional exercise) are mainly positively associated with both FAD motives. Regarding the psychological correlates, low self-esteem (Laghi et al., 2019; Ritz et al., 2024), body-related self-esteem (Griffin and Vogt, 2020; Hill and Lego, 2019), anxiety (Gates and Odar Stough, 2022; Laghi et al., 2021; Ritz et al., 2024; Roosen and Mills, 2015) and depressive symptoms (Ritz et al., 2024), as well as emotion dysregulation (Azzi et al., 2021; Horvath et al., 2020; Laghi et al., 2019), have been related to FAD behaviors. Regarding social correlates, loneliness (Ritz et al., 2024), social anxiety (Pompili et al., 2024) and social peer pressure (Hill et al., 2021) appear to be uniquely associated with caloric compensation motives. Regarding consequences, alcohol-related problems have been associated with FAD for both motives (Berry et al., 2024).
Longitudinal studies on FAD behaviors
Although these studies have provided a better understanding of the psychosocial correlates of FAD behaviors, they have certain limitations. They rely on cross-sectional designs and therefore cannot capture changes in FAD behaviors over time or clarify potential causal relationships among variables (Berry et al., 2024; Shepherd et al., 2021b). To our knowledge, only two studies have conducted longitudinal examinations. One three-wave longitudinal follow-up over a period of six weeks demonstrated that engagement in FAD behaviors for alcohol enhancement motives predicted increased alcohol use (but not alcohol-related consequences) across the follow-up period, although this effect did not emerge consistently at every time point (Herchenroeder and Yeung, 2024). By contrast, alcohol use and its consequences were not predictive of FAD-related intoxication behaviors. Notably, this study focused exclusively on the alcohol enhancement motive, without examining the caloric compensation motive, which limits the scope of the findings (Berry et al., 2024). In addition, only alcohol-related variables were examined, excluding potentially relevant predictors such as disordered eating (Berry et al., 2024), and dysfunctional exercise patterns. Importantly, another major limitation concerns the retrospective nature of the data, which relies on self-reported behaviors recalled from a “typical” alcohol-consumption episode. As a result, participants were asked to estimate, on average, how often they restrict their food intake when drinking alcohol to reach intoxication more quickly.
More recently, an EMA study examined whether individuals reporting higher levels of subjective alcohol intoxication on days when they engaged in FAD differed from drinking days without FAD, and whether increased subjective alcohol intoxication was positively associated with same-day negative consequences (Herchenroeder and Yeung, 2026). The results showed a significant mediation effect for FAD intoxication, such that on days when students engaged in FAD-intoxication they reported higher subjective alcohol intoxication than on days when they consumed alcohol without FAD-intoxication. In turn, on days when students reported higher subjective alcohol intoxication, they also reported more negative alcohol-related consequences. In contrast, the mediation effect for the FAD caloric compensation model was not significant.
Despite its methodological strengths, this study presents several limitations that should be acknowledged. First, it primarily focused on the longitudinal role of FAD behaviors related to subjective alcohol intoxication, by contrasting FAD–intoxication and FAD–caloric compensation. As such, it provided limited insight into the specific contribution of caloric-restriction–based behaviors independent of intoxication-related processes. Second, the presence of FAD–calories and FAD–intoxication was operationalized using binary indicators (yes/no), without a detailed characterization of the specific behaviors involved or their intended temporal sequencing (e.g., restriction before, during, or after alcohol consumption). This approach may have obscured meaningful heterogeneity in FAD practices. Finally, affective states were included solely as covariates rather than being examined as primary variables of interest, thereby limiting conclusions regarding the dynamic role of affect in the emergence and maintenance of FAD behaviors.
The value of Ecological Momentary Assessment measures for capturing real-time behavioral dynamics
Ecological Momentary Assessment (EMA) provides a methodological framework for assessing individuals’ behaviors and subjective experiences as they unfold in real time and within their natural environments (Shiffman et al., 2008). By minimizing recall bias inherent to retrospective self-reports, EMA enhances ecological validity and allows for the examination of behavioral dynamics across time (e.g., different moments of the day) and contexts (e.g., being alone versus in the presence of peers). EMA is based on repeated assessments that may be event-contingent (e.g., following a specific behavior) and/or randomly prompted across time. The intensive longitudinal nature of EMA makes it possible to capture within-person variability in behaviors and experiences across situations and moments, thereby enabling the investigation of temporal sequences and providing a more fine-grained understanding of the relationships between contextual triggers, behaviors, and their subsequent consequences.
Advances in mobile technology have further facilitated EMA implementation, with data now commonly collected via smartphone applications rather than paper-and-pencil diaries, which are prone to data loss. These technological developments have also been associated with high participant compliance, estimated at around 90% (Hufford et al., 2002). EMA protocols have been widely applied across a range of psychopathological conditions, including addictive behaviors, eating disorders, anxiety disorders, depression, and bipolar disorder (for reviews, see Shiffman et al., 2008; Wayda-Zalewska et al., 2022).
Purpose of the study
FAD behaviors are highly prevalent among young adults and of particular concern given their association with alcohol use, eating disorder behaviors, psychosocial vulnerabilities, and alcohol-related negative consequences. A substantial body of research has contributed to a better understanding of the correlates and determinants of FAD. However, most existing studies rely on cross-sectional designs and retrospective self-report measures, which limit the ability to capture the temporal dynamics of FAD behaviors. This methodological constraint hampers our understanding of how these behaviors unfold over time (before, during, and/or after drinking episodes) and how they are organized around specific motivations, such as enhancing alcohol effects or compensating for caloric intake. The lack of a temporal, process-oriented perspective restricts the identification of behavioral patterns and, consequently, the development of targeted interventions aimed at the specific moments when these behaviors are most likely to occur.
Moreover, although correlational studies have documented associations between FAD behaviors and various psychosocial factors, they do not allow for the identification of the contextual or psychological triggers that precipitate these behaviors. While EMA represents a promising approach to capturing FAD behaviors in real time and within naturalistic settings, empirical studies adopting this methodology remain scarce
