The purpose of this study is to quantitatively check whether group art therapy through online face-to-face has an effect on the happiness, depression, and perceived social support of pregnant women. This study recruited participants from general primiparous women under 15 to 30 weeks of pregnancy, and designed the parallel design and pre-post experiments of the experimental group and the control group. The 45 voluntarily recruited pregnant women were randomly assigned according to the sequence using Excel's random number value, and 20 in the experimental group and 19 in the control group were finally statistically processed except for the middle dropouts. In order to find out the therapeutic effect, a questionnaire was conducted before and after the program using the maternity happiness scale, the depression scale, and the social support scale. An independent sample t-test was conducted as a data analysis method for the questionnaire. The results of this study are summarized as follows. First, the happiness of pregnant women increased after online face-to-face group art therapy, which was significantly different from the control group. Second, after online face-to-face group art therapy, pregnant women decreased depression, which was significantly different from the control group. Third, after online face-to-face group art therapy, perceived social support of pregnant women increased, which was significantly different from the control group. These findings suggested the possibility of expanding a new method of art therapy called online face-to-face in the form of group art therapy and confirmed the possibility that online face-to-face group art therapy can no longer play a role as a second choice due to the pandemic.
