Aim: This study aimed to investigate mass psychogenic illness (MPI) across various institutional settings worldwide, identifying its triggering factors and symptom profiles. Additionally, it sought to analyze the organizational and psychosocial factors contributing to MPI outbreaks and to propose recommendations for their prevention.
Method: The research was based on a dataset comprising peer-reviewed articles published between 2000 and 2025, written in English and documenting MPI cases within specific institutional contexts. A systematic review was conducted using PubMed, Scopus and Web of Science databases. Employing qualitative content analysis, 14 case studies were evaluated through descriptive and thematic approaches, focusing on institutional categories, triggering factors and symptom profiles.
Results: The analysis revealed that 85.7% (12/14) of MPI cases occurred in school settings, while 7.1% (1/14) was reported to occur in a hospital and 7.1% (1/14) in an office environment. In schools, emotional vulnerability among adolescents, academic stress, misinformation dissemination and group interactions emerged as primary triggers. In contrast, environmental perceptions and dramatic interventions were prominent in hospital and office cases. The most frequently reported physical symptoms included nausea, headaches and dizziness, while psychical symptoms such as anxiety and panic were less common. Notably, MPI cases were more prevalent among female students.
Conclusion: MPI is predominantly observed in school environments, driven by stress, misinformation and social contagion. Being less frequent in adult-oriented settings, its presence reflects distinct dynamics rather than immunity. The study highlights the critical role of organizational culture and leadership in preventing MPI. Strengthening psychosocial support systems, implementing stress management and fostering transparent communication within institutions can mitigate MPI risks.

Kitlesel Psikojenik Hastalığının Kurumsal Bağlamı, Tetikleyicileri ve Semptomları: Literatüre Dayalı İçerik Analizi

Amaç: Bu çalışma, dünya çapında çeşitli kurumsal ortamlarda kitlesel psikojenik hastalıkları (MPI) araştırmayı, tetikleyici faktörleri ve semptom profillerini belirlemeyi amaçlamıştır. Ayrıca, MPI salgınlarına katkıda bulunan organizasyonel ve psikososyal faktörleri analiz etmeyi ve bunların önlenmesi için öneriler sunmayı amaçlamıştır.
Yöntem: Araştırma, 2000 ile 2025 yılları arasında yayınlanmış, İngilizce yazılmış ve belirli kurumsal bağlamlarda MPI vakalarını belgeleyen hakemli makalelerden oluşan bir veri setine dayanmaktadır. PubMed, Scopus ve Web of Science veri tabanları kullanılarak sistematik bir inceleme yapılmıştır. Nitel içerik analizi kullanılarak, 14 vaka çalışması kurumsal kategorilere, tetikleyici faktörlere ve semptom profillerine odaklanan tanımlayıcı ve tematik yaklaşımlarla değerlendirilmiştir.
Bulgular: Analiz, MPI vakalarının %85,7'sinin (12/14) okul ortamlarında meydana geldiğini ortaya koyarken, %7,1'inin (1/14) hastanede ve %7,1'inin (1/14) ofis ortamında meydana geldiği bildirilmiştir. Okullarda, ergenler arasındaki duygusal kırılganlık, akademik stres, yanlış bilgi yayma ve grup etkileşimleri birincil tetikleyiciler olarak ortaya çıkmıştır. Buna karşılık, hastane ve ofis vakalarında çevresel algılar ve dramatik müdahaleler öne çıkmıştır. En sık bildirilen fiziksel semptomlar arasında mide bulantısı, baş ağrısı ve baş dönmesi yer alırken, anksiyete ve panik gibi psişik semptomlar daha az yaygındı. MPI vakalarının kız öğrenciler arasında daha yaygın olması dikkat çekicidir.
Sonuç: MPI, stres, yanlış bilgilendirme ve sosyal bulaşma nedeniyle ağırlıklı olarak okul ortamlarında gözlemlenmektedir. Yetişkinlere yönelik ortamlarda daha az sıklıkta görülmesi, bağışıklıktan ziyade farklı dinamikleri yansıtmaktadır. Çalışma, MPI'nin önlenmesinde kurum kültürü ve liderliğin kritik rolünü vurgulamaktadır. Psikososyal destek sistemlerinin güçlendirilmesi, stres yönetiminin uygulanması ve kurumlar içinde şeffaf iletişimin teşvik edilmesi MPI risklerini azaltabilir.
