Araştırmacılar için aynı konu hakkındaki araştırmaların bulgularını sentezlemek ve organize etmek oldukça önemlidir. Öte yandan farklı örneklem, araştırma deseni ve istatistiksel tekniklerin kullanıldığı araştırmaların bulgu ve sonuçlarını yorumlamak oldukça zor bir süreçtir. Meta-analiz araştırmalarından elde edilen bulguların birleştirilmesi daha doğru sonuçlara ulaşmaya katkı sağlamaktadır. Aynı konuya ya da probleme ilişkin yürütülen meta analiz çalışmalarının bulgularının birleştirilmesinde ise ikinci dereceden meta-analiz yöntemi kullanılmaktadır. Bu çalışmanın amacı ikinci dereceden meta analiz araştırmasını tanıtmaktır. Bu amaç doğrultusunda literatür taraması yapılmıştır. İkinci dereceden meta analiz araştırmasının tanımı yapılmıştır. Öte yandan ikinci dereceden meta analiz araştırmasının aşamaları belirlenmiştir. Bunların yanında ikinci dereceden meta analiz araştırmalarında dikkat edilmesi gereken noktalar ve bu noktalara ilişkin literatürden hareketle çözüm önerileri ortaya konmuştur. İkinci dereceden meta analiz araştırmalarında dikkat edilecek konular; örtüşme problemi, etki büyüklüğü indeksi seçme, etki büyüklüğü birleştirme, meta analizlerin kalitesini belirleme, moderatör değişkenleri belirleme, istatistiksel model seçimi ve etki büyüklüğünü kodlama olarak belirlenmiş ve açıklanmıştır.
