The purpose of this study was to examine if there is a connection between anger, aggression, and problem-solving abilities in secondary school students. The study's sample includes 273 students enrolled in secondary schools in Manisa for the 2020-2021 academic year. The convenience sampling method, which is one of the nonrandom sampling methods, was used to determine the study's sample. The data for the study was collected using the Anger Scale for Children, the Aggression Scale, and the Problem-Solving Inventory for Children. The t-test, Spearman Correlation analysis, and multiple regression analysis were conducted to analyse the data. Looking at the data, it was determined that the anger levels of female students were higher than those of male students. The aggression levels of male students are higher than female students. It was discovered that anger and aggression have a positive relationship, whereas anger levels have a negative relationship with self-control, avoidance, and total problem solving. Another outcome of the study is that problem-solving abilities predict anger and aggression. A negative association was shown between problem solving, anger, and agression among students.
