Temper tantrums in children Toddlers often cause parents frustration so a solution is needed to overcome this. This study aims to determine the effect of therapeutic group therapy on the incidence of temper tantrums in toddler-aged children. The research design used in this research is a quasi-experimental research design with a pretest–posttest approach using a control group. This research was conducted in October 2023 in Pakisaji, Malang Regency. This research involved 9 children (aged 2-3 years) in the Pakisaji sub-district area as the treatment group and 9 other children as the control group. The treatment group was given 6 sessions of therapeutic group therapy over a period of 3 weeks. The results of the analysis using the paired sample test showed that in the treatment group there was a significant difference in the value of children's temper tantrums before and after being given treatment, namely with a value of p=0.039 (<0.05). Meanwhile, in the control group, the p value = 0.085 (> 0.05) was obtained, which indicated that there was no significant difference. The results of the analysis of differences in the incidence of temper tantrums before and after treatment between the treatment group and the control group were carried out using an independent sample t test and the results obtained were p=0.387 (>0.05). These results show that there is no significant difference in the incidence of pre and post temper tantrums between the treatment and control groups. The conclusion of this study proves that there is no significant influence from the application of Therapeutic Group Therapy on the incidence of temper tantrums in toddler. because there are many factors that can influence it including the parenting style of parents.
