Offering financial incentives to participants for their participation in qualitative research is a common practice that improves recruitment in a study. However, the state of incentive use in qualitative research across fields is unknown. This methodological review aimed to examine the state of incentive use in qualitative research across fields in the context of the United States. Using descriptive statistics and negative binomial regression, we examined 698 cases of incentives for 627 unique full-text empirical qualitative research articles and determined the influencing factors for the amounts of incentives used in qualitative research studies. The results showed that publication year, field of research, and sample size function as influencing factors in the amount of incentives offered in qualitative studies. Of the 698 cases identified through the systematic search, incentive amounts (US Dollar) varied from minimum $5.00 to maximum $500.00 with mean of $31.7 (SD=32.1). The incentive amounts (US Dollar) with the inflation rate varied from $5.00 to maximum $565.00 with a mean of $36.6 (SD=37.4). Our study suggests that incentives in qualitative research are shaped by disciplinary and methodological contexts, and our review provides practical implications to guide researchers’ decisions. This study ignites a deeper dialogue about the use of incentives in qualitative research and reporting practices to assist researchers in enhancing the effectiveness of using incentives within their respective fields.

Nitel araştırmalara katılan bireylere finansal teşvikler sunmak, katılımcı teminini kolaylaştıran yaygın bir uygulamadır. Ancak, nitel araştırmalarda teşvik kullanımının disiplinler arası durumu tam olarak bilinmemektedir. Bu yöntemsel derlemenin amacı, Amerika Birleşik Devletleri bağlamında disiplinler arası nitel araştırmalarda finansal teşvik kullanımının durumunu incelemektir. Tanımlayıcı istatistikler ve negatif binom regresyon kullanılarak, 627 özgün tam metin ampirik nitel araştırma makalesinde yer alan 698 teşvik vakası incelenmiş ve nitel araştırmalarda kullanılan teşvik miktarlarını etkileyen faktörler belirlenmiştir. Bulgular, yayın yılı, araştırma alanı ve örneklem büyüklüğünün, nitel çalışmalarda sunulan teşvik miktarlarını etkileyen faktörler olarak işlev gördüğünü göstermektedir. Sistematik arama ile belirlenen 698 vaka kapsamında, teşvik miktarları (ABD doları) en az 5,00 dolar ile en fazla 500,00 dolar arasında değişmiş olup, ortalama 31,7 dolar (SS=32,1) bulunmuştur. Enflasyon oranına göre ayarlanan teşvik miktarları ise 5,00 dolar ile 565,00 dolar arasında değişmiş olup, ortalama 36,6 solar (SS=37,4) olarak hesaplanmıştır. Çalışmamız, nitel araştırmalarda teşviklerin disipliner ve yöntemsel bağlamlar tarafından şekillendiğini ve araştırmacıların karar alma süreçlerine rehberlik edecek pratik çıkarımlar sunduğunu göstermektedir. Bu çalışma, nitel araştırmalarda teşvik kullanımına ve raporlama uygulamalarına ilişkin daha derin bir tartışma başlatarak araştırmacıların kendi alanlarında teşvikleri daha etkili biçimde kullanmalarına katkı sağlamayı amaçlamaktadır.
