The purpose of this study is to examine the debates
about the validity and reliability criteria that are frequently addressed in
the qualitative research tradition. For
this purpose, concerns about validity and reliability issue have been analyzed
in detail based on epistemological and theoretical conceptualizations. As a
result of the analysis, it is seen that the issue of validity and reliability
is important and researchers propose various conceptual and theoretical
approaches to the subject. In addition to the views suggesting
that these propositions regarding validity and reliability issue can be defined
in various ways and function differently based on epistemological and
theoretical differences. It is also seen that
there are views emphasizing that the quality of each study should be assessed
separately with a more rhetorical approach because it refuses to have
pre-determined criteria in qualitative researches. Based on this analysis, the
general conclusion that measuring the quality of qualitative studies is a
controversial issue and there is no single way to measure quality has been
obtained.

Nitel Araştırmada Geçerlik ve Güvenirlik: Kuramsal Bir İnceleme

Öz

Bu çalışmanın amacı, nitel araştırma geleneği içinde son dönemlerde
sıklıkla ele alınan geçerlik ve güvenirlik ölçütlerine ilişkin tartışmaları
incelemektir. Bu amaçla geçerlik ve güvenirlik sorunsalına ilişkin endişeler,
konuyla ilgili epistemolojik ve kuramsal kavramsallaştırmalara dayalı olarak
ayrıntılı bir şekilde çözümlenmeye çalışılmıştır. Çözümlemeler sonucunda geçerlik ve güvenirlik konusunun son yıllarda giderek
önem kazanmaya başladığı ve araştırmacıların konuya yönelik çeşitli yaklaşımlar
önerdikleri görülmüştür. Bu önermelerde geçerlik
ve güvenirliğin çeşitli şekillerde tanımlanabileceğini ve epistemolojik ve kuramsal
farklılıklara dayalı olarak farklı şekilde işlev görebileceğini ortaya koyan
görüşlerin yanında, nitel araştırmalarda önceden belirlenmiş ölçütlerin
olmasını reddeden, dolayısı ile daha retorik bir yaklaşımla her çalışmanın
niteliğinin ayrı değerlendirilmesi gerektiğini vurgulayan görüşlerin olduğu da
görülmektedir. Bu çözümlemeye dayalı olarak nitel çalışmalarda geçerlik ve güvenirlik
kavramlarının tartışmalı bir konu olduğu ve nitel çalışmaların niteliğini
ölçmek için tek bir yolun olmadığı genel sonucuna ulaşılmıştır.
