- Purpose: Since the term orthorexia nervosa (ON) was coined from the Greek (ὀρθός, right and ὄρεξις, appetite) in 1997 to describe an obsession with “correct” eating, it has been used worldwide without a consistent definition. Although multiple authors have proposed diagnostic criteria, and many theoretical papers have been published, no consensus definition of ON exists, empirical primary evidence is limited, and ON is not a standardized diagnosis. These gaps prevent research to identify risk and protective factors, pathophysiology, functional consequences, and evidence-based therapeutic treatments. The aims of the current study are to categorize the common observations and presentations of ON pathology among experts in the eating disorder field, propose tentative diagnostic criteria, and consider which DSM chapter and category would be most appropriate for ON should it be included.Methods: 47 eating disorder researchers and multidisciplinary treatment specialists from 14 different countries across four continents completed a three-phase modified Delphi process, with 75% agreement determined as the threshold for a statement to be included in the final consensus document. In phase I, participants were asked via online survey to agree or disagree with 67 statements about ON in four categories: A–Definition, Clinical Aspects, Duration; B–Consequences; C–Onset; D–Exclusion Criteria, and comment on their rationale. Responses were used to modify the statements which were then provided to the same participants for phase II, a second round of feedback, again in online survey form. Responses to phase II were used to modify and improve the statements for phase III, in which statements that met the predetermined 75% of agreement threshold were provided for review and commentary by all participants.Results: 27 statements met or exceeded the consensus threshold and were compiled into proposed diagnostic criteria for ON.Conclusions: This is the first time a standardized definition of ON has been developed from a worldwide, multidisciplinary cohort of experts. It represents a summary of observations, clinical expertise, and research findings from a wide base of knowledge. It may be used as a base for diagnosis, treatment protocols, and further research to answer the open questions that remain, particularly the functional consequences of ON and how it might be prevented or identified and intervened upon in its early stages. Although the participants encompass many countries and disciplines, further research will be needed to determine if these diagnostic criteria are applicable to the experience of ON in geographic areas not represented in the current expert panel.Level of evidence: Level V: opinions of expert committees.© 2022, The Author(s).

- Background: Given the high prevalence of clinically relevant premenstrual symptoms and the associated impairment, there is a need for effective treatments. Initial evidence suggests cognitive-behavioural therapy (CBT) as an effective treatment for premenstrual dysphoric disorder (PMDD). The aim of the current randomized clinical trial was to evaluate an Internet-based CBT (iCBT) to reduce the burden of PMDD. Methods: In all, 174 women with PMDD were recruited via newspaper articles, flyers, and social media. They were randomized to a treatment group (TG; n = 86) or waitlist control group (CG; n = 88). Women of the TG received an 8-week therapist-guided iCBT. Data were assessed before and after treatment/waiting, and 6 months after intervention with prospective symptom diaries and questionnaires in the pre-menstrual phase. Treatment effects and moderators were analysed using hierarchical linear modelling. Results: Significant time x group interaction effects on functional impairment and psychological impairment, impact on everyday life, symptom intensity, and symptom disability in favour of the TG indicated the efficacy of the treatment. Follow-up assessments demonstrated treatment effects to be stable until 6 months after treatment. Additionally, significant interactions with moderator variables were found. In the TG, higher levels of active coping and lower levels of support-seeking coping were associated with stronger improvement in interference in everyday life and symptom intensity. In addition, lower levels of perceived stress were associated with stronger improvement in functional impairment. Conclusion: The iCBT was highly effective in reducing the burden of PMDD. It appears to be particularly important to address coping styles and stress management in the treatment. (C) 2019 S. Karger AG, Basel
