This content analysis study aims to methodologically evaluate the appropriateness of meta-analyses, conducted on Turkish samples on a variety of topics. Through an exhausting literature review, 80 meta-analyses were gathered together and coded into a detailed Meta-Analysis Evaluation Form.  The form consisted of 59 items (1 = Not Present, 2 = Present and 3 = Not Mentioned) both regarding the study and substantial characteristics. Two researchers coded the studies and the reliability of the coding of five studies indicated no problems with consistencies of the codings (Kappa= .90). According to the results, the most often encountered problem in meta-analyses was reporting both the fixed and random effects analyses without making a priori decision about the model choice. It was found that 60.0% of the meta-analyses investigated by the current study excluded studies conducted abroad which resulted underrepresentation of the literature.  Furthermore, the studies suffered from a small sample size issues. The methodology (how the studies were selected, coding form, reliability of the codings and etc.) was not explained clearly in more than a quarter of the studies. Therefore, it would be hard to claim that they have sufficient level of internal and external validity. It was hoped that researchers may benefit from the results of the current study to conduct better quality meta-analysis in the future. Ozet Bu icerik analizi calismasinin amaci Turkiye'de yapilan meta analiz calismalarinin metodolojik degerlendirmesinin yapilmasidir. Meta Analiz Degerlendirme Formu uzerinden Turkiye literaturundeki 80 meta analiz calismasi kodlanmistir. Degerlendirme formu calismalarin kunyelerini ve meta analiz yonteminin kullanimindaki cesitlenmeyi iceren 59 (Evet-Hayir-Belirtilmemis seklinde cevaplanabilecek) maddeyi kapsamaktadir. Iki arastirmaci kodlamalari gerceklestirmis ve oncesinde bes calismalik bir pilot calisma uzerinden kodlamalari arasindaki uyum hesaplanmis ve Kappa katsayisi (Kappa= .90) yeterli duzeyde bulunmustur. Sonuclara gore meta analiz calismalarindaki en belirgin problem herhangi bir tercihte bulunmaksizin sabit ve rasgele etkiler modellerinin birlikte rapor edilmesidir. Calismalarin %60'inda yurtdisi calismalar dahil edilmeksizin Turkiye orneklemindeki calismalari kullanarak meta analiz yapilmistir. Yurtdisi calismalara yer veren meta analizlerde ise sayinin cok dusuk oldugu dolayisiyla orneklemin temsil ediciliginin dusuk oldugu gorulmustur. Meta analizlerde orneklem buyuklugunun sayica cok yetersiz oldugu ya da olmadigi gorulmustur. Calismalarin dortte birinden fazlasinda metodoloji bolumunde calismalarin nasil toplandigi, kodlama formu, kodlamalarin guvenirligi gibi konular aciklanmamistir. Bu durum ilgili meta analiz calismalarinin guvenirlik ve gecerligini dusurmektedir. Mevcut degerlendirme calismasinin, gelecekte meta analiz konusunda calisacak arastirmacilara metodolojik bakimdan daha kaliteli arastirmalar ortaya koymalari hususunda katki saglayacagi beklenmektedir.
