Year 2025, Volume: 17 Issue: Supplement 1, 393 - 402
https://doi.org/10.18863/pgy.1760054

Abstract

Objective: The number of studies conducted on schizophrenia in Türkiye has begun to increase, particularly since the 2000s, in line with global trends. This bibliometric study aims to shed light on the development of schizophrenia studies conducted in Türkiye and the country's contribution to global medical data presentation over the last 20 years, as well as to guide clinicians.
Method: Publications published between 2005 and 2024 with at least one author from a Turkish institution were included in the study by selecting the keyword ‘schizophrenia’ in the SCI-E (Science Citation Index Expanded) index in the Web of Science (WoS) Core Collection database. Database analysis and visualisations were performed using the VOSviewer programme.
Results: A total of 604 articles were identified through the search. Although the number of publications has generally increased, with a few exceptions, 2020 and 2021 were the most productive years, with 49 and 53 articles, respectively. The total number of citations is 10276, the average citation frequency per article is 17.01, and the h-index is 51. The three most active Turkish authors in the field of schizophrenia are Alp Üçok, Köksal Alptekin, and Emre Bora. The Bulletin of Clinical Psychopharmacology is the journal that has contributed the most, with 92 articles. The most productive Turkish institution in this field is the Istanbul Faculty of Medicine, with 44 publications.
Conclusion: This study provides an opportunity to summarise a broad field such as schizophrenia, serving as a guide for researchers to plan their studies in the right areas with the right people by keeping abreast of developments in the field and contributing to the literature.

Abstract

Amaç: Türkiye’de şizofreni ile ilgili yapılan çalışmaların sayısı, küresel eğilime paralel olarak özellikle 2000'lerden itibaren artmaya başlamıştır. Bu bibliyometrik çalışma, Türkiye'de yürütülmüş şizofreni çalışmalarının ve ülkenin global tıbbi veri sunumuna katkısının son 20 yıllık gelişimine ışık tutmayı ve klinisyenlere yol göstermeyi amaçlamaktadır.
Yöntem: Web of Science (WoS) Core Collection veri tabanında SCI-E (Science Citation Index Expanded) dizininde ‘şizofreni’ anahtar sözcüğü seçilerek 2005-2024 arasında yayınlanmış en az bir yazarın Türk bir kurumdan olduğu yayınlar çalışmaya dahil edilmiştir. Veri tabanı analizi ve veri tabanlı görselleştirmeler VOSviewer programı ile gerçekleştirilmiştir.
Bulgular: Arama sonucunda toplam 604 makaleye ulaşılmıştır. Yayın sayısının birkaç istisna yıl dışında genel olarak artmakta olduğu gözlenmekle birlikte 2020 ve 2021, sırasıyla 49 ve 53 makale ile en üretken yıllar olmuştur. Toplam atıf sayısı 10276, her bir makalenin ortalama atıf sıklığı 17,01 ve h-indeksi 51’dir. ‘Bulletin of Clinical Psychopharmacology’ 92 makale ile en çok katkıda bulunan dergidir. Bu alanda en üretken Türk kurum 44 yayınla İstanbul Üniversitesi İstanbul Tıp Fakültesi olmuştur.
Sonuç: Bu çalışma şizofreni gibi geniş bir alanı özetleme olanağı sağlayarak çalışmacıların kendi çalışmalarını alanın nabzını tutarak doğru kişilerle doğru alanlarda planlamalarına ve literatüre katkıda bulunmaları için bir rehber olma niteliği taşıyabilir.
