Worum geht es in dieser Arbeit?

ABSTRACT Self-control is an individual's ability to regulate thoughts, emotions, and behaviors in accordance with goals and applicable norms, which plays an important role in students' academic success and social adjustment. This study was motivated by the identification of several eleventh-grade students at SMA Negeri 1 Gerung who demonstrated low self-control, as indicated by frequent lateness to class, becoming easily angry when reprimanded, noncompliance with school rules, and conflicts with peers. This study aimed to determine the effect of Rational Emotive Behavior Therapy (REBT) counseling on the self-control of eleventh-grade students. A quantitative approach with a one-group pretest-posttest design was employed. The research subjects were selected using purposive sampling based on the results of an initial assessment of self-control using a Likert-scale questionnaire. The intervention was conducted through group counseling using the REBT approach, consisting of problem identification, identification of irrational thoughts, challenging irrational beliefs, developing rational beliefs, changing emotional and behavioral responses, and practicing the acquired skills. Data were analyzed using the Shapiro-Wilk normality test and the Paired Sample t-Test with the assistance of SPSS. The results showed an increase in the mean self-control score from 103.67 in the pretest to 128.00 in the posttest. The Paired Sample t-Test yielded t = 17.541, df = 5, and p = 0.000 < 0.05. Therefore, group counseling using the REBT approach had a significant effect on improving students' self-control and can serve as an alternative guidance and counseling service in schools.
