Multidimensional Meaning in Life: Turkish Validation of the 3DM Using a Bifactor Model

Öz

Recent research highlights the importance of multidimensional measurement in assessing meaning in life. The Three Dimensional Meaning in Life Scale (3DM) is a self-report measure based on a tripartite framework including significance, coherence, and purpose. The present study aimed to assess the psychometric properties of the Turkish version of the 3DM. The first-order confirmatory factor analysis confirmed that the Turkish version replicated the original three-factor structure of the 3DM. The model showed a good fit to the present data. The bifactor model of the 3DM supported a multidimensional structure of meaning in life, and measurement invariance indices demonstrated consistent psychometric properties across gender groups. The 3DM subscales had good reliability, with strong item-total correlations ranging from .47 to .76. They had significant positive associations with meaning in life and well-being indicators. The results provided evidence for the structural and convergent validity of the 3DM. Overall, the Turkish 3DM is a valid and reliable measure.

Çok Boyutlu Yaşamda Anlam: 3DM Ölçeğinin Bifaktör Modeli Aracılığıyla Türkçe Güvenirlik ve Geçerliği Çalışması

Öz

Son zamanlarda yapılan araştırmalar, yaşamda anlamın değerlendirilmesinde çok boyutlu ölçme araçlarının önemini vurgulamaktadır. Üç Boyutlu Yaşamda Anlam Ölçeği (3DM) kişisel anlam, tutarlılık ve amaç olmak üzere üç faktörlü bir öz bildirim ölçeğidir. Bu çalışma, 3DM ölçeğinin Türkçe versiyonunun psikometrik özelliklerini değerlendirmeyi amaçlamıştır. Birinci düzey doğrulayıcı faktör analizi, Türkçe 3DM’in orijinal üç faktörlü yapısını doğruladığını bulmuştur. Model mevcut verilere iyi bir uyum göstermiştir. 3DM’nin bifaktör modeli, yaşamda anlamın çok boyutlu bir şekilde değerlendirilmesini desteklemiş ve ölçme değişmezliği endeksleri cinsiyet grupları arasında tutarlı psikometrik özellikler göstermiştir. 3DM alt ölçekleri .47 ile .76 arasında değişen güçlü madde-toplam korelasyonları ile iyi bir güvenirlik göstermiştir. Alt boyutların diğer yaşamda anlam ve iyi oluş göstergeleri ile anlamlı pozitif ilişkileri olduğu bulunmuştur. Sonuçlar, 3DM’nin yapısal ve yakınsak geçerliliği için kanıt sağlamıştır. Sonuç olarak, 3DM’in Türkçe versiyonu geçerli ve güvenilir bir ölçme aracıdır.
