Psychometric Properties of Turkish Version of the Problematic Gambling Severity Index

Abstract

Objective: The aim of this study was to examine the psychometric properties of the Problematic Gambling Severity Index (PGSI) in a study group consisting of participants with and without a diagnosis of pathological gambling disorder. Method: Data were collected from 539 individuals, 60 of whom were diagnosed with gambling disorder. The Problematic Gambling Severity Index (PGSI), South Oaks Gambling Screening Test (SOGS) and demographic information form were used to collect data. Linguistic equivalence, validity, reliability and item statistics of the index were examined. Results: Construct validity and criterion-related validity analysis were performed for validity estimations. As a result of the confirmatory factor analysis performed to examine the construct validity, it was seen that the structure of the scale consisting of nine items and a single sub-dimension was valid in Turkish culture. To determine criterion-related validity, the relationship between the PGSI and the SOGS was examined. The analysis showed that there was a significant relationship between the two scales. For the reliability estimations, the internal consistency analysis of the index and test-retest reliability were examined. The internal consistency level was calculated with the Cronbach's alpha coefficient and it was seen that the internal consistency was high. In the test-retest analysis, it was seen that the relationship between the administrations of the scale in the same group at two different times was high. Conclusion: The PGSI is a valid and reliable measurement that can be used both in clinical research and practical studies to be conducted in Turkey, and in survey studies to be conducted on the general population.

Problemli Kumar Oynama Şiddet Endeksi Türkçe Versiyonunun Psikometrik Özellikleri

Öz

Amaç: Bu çalışmada Problemli Kumar Oynama Şiddet Endeksi’nin kumar oynama bozukluğu tanısı olan ve olmayan katılımcılardan oluşan bir çalışma grubunda psikometrik özelliklerinin incelenmesi amaçlanmaktadır. Yöntem: Altmışı kumar oynama bozukluğu tanısı olan 539 kişiden veri toplanmıştır. Verilerin toplanmasında Problemli Kumar Oynama Şiddet Endeksi, South Oaks Kumar Tarama Testi ve demografik bilgi formu kullanılmıştır. Endeksin dilsel eşdeğerlik, geçerlik, güvenirlik ve madde istatistikleri incelenmiştir. Bulgular: Geçerlik kestirimleri için yapı geçerliği ve ölçüt bağıntılı geçerlik analizi yapılmıştır. Yapı geçerliğini incelemek için yapılan doğrulayıcı faktör analizi sonucunda ölçeğin dokuz maddeden ve tek alt boyuttan oluşan yapısının Türk kültüründe geçerli olduğu görülmüştür. Ölçüt bağıntılı geçerliği tespit etmek için Kumar Oynama Şiddet Endeksi ile South Oaks Kumar Tarama Testi arasındaki ilişki incelenmiştir. Yapılan analizler iki ölçek arasında anlamlı bir ilişki olduğunu göstermiştir. Güvenirlik kestirimleri için endeksin iç tutarlık analizi ve test-tekrar test güvenirliği incelenmiştir. İç tutarlılık düzeyi Cronbach alfa katsayısı ile hesaplanmış ve iç tutarlılığının yüksek olduğu görülmüştür. Yapılan test-tekrar test analizlerinde ölçeğin iki farklı zamanda aynı gruptaki uygulamaları arasındaki ilişkinin yüksek olduğu görülmüştür. Sonuç: Araştırma bulguları, Problemli Kumar Oynama Şiddet Endeksi’nin Türkiye’de yürütülecek hem klinik araştırma ve uygulama çalışmalarında hem de genel nüfus üzerinden yürütülecek tarama çalışmalarında kullanılabilecek geçerli ve güvenilir bir ölçme aracı olduğunu ortaya koymuştur.
