In this study, we aim to evaluate the research trends of filial therapy or Child Parent Relationship Therapy (CPRT) for the purpose of providing basic data for the distinction about a further strategy to research the therapy. 32 articles were included in this study, which were published from 2010 to 2020, after withdrawal of unsuitable articles from search results in KISS and RISS. The status of publication, author/affiliation characteristics, study design, subject or participants, structure of the articles, and the conclusion were analyzed with the 32 articles. As a result of this study, we observed that the therapy was applied in the clinical field continuously, and both quantitative and qualitative manner were used to analyze the efficacy and phenomenon in the session. The field of the therapy was observed as increasing the number of articles and enlarging the border of the field by developing a new program emerged with art or preliminary parent training. A hybrid quantitative and qualitative study design were observed in many articles. However, the study design shall be upgraded in the following studies, and improve the evidence level if the field. Throughout the study, we figured out the current status of filial therapy or CPRT related studies and expect that the results can be used as basic data for advanced research on CPRT by providing direction and strategy.
