“…According to the bibliometric analysis results, the United States is leading in PCIT studies with a total of 422 publications (Chaffin et al, 2004;Puliafico et al, 2012;Luby, 2013;Carpenter et al, 2014;Kennedy et al, 2016;Rothenberg et al, 2019;Niec et al, 2020;Agazzi et al, 2022). However, with studies conducted in recent years, it is seen that Germany (n = 23), New Zealand (n = 7), and Australia (n = 44) have gained momentum in PCIT studies (Furuzawa et al, 2020;Woodfield et al, 2020;Kamo et al, 2021;Woodfield et al, 2021). Niec et al (2018) similarly found that PCIT has become widespread in many countries in recent years, including Australia, Germany, Japan, and France.…”
