Abstract

This study examined the influence of self-concept on prosocial behavior among ninth-grade students at UPTD SMP Negeri 10 Kupang during the 2025/2026 academic year. A quantitative approach with a causal-associative design was employed. The population consisted of 320 students, and 80 students were selected using simple random sampling. Data were collected through self-concept and prosocial behavior questionnaires, each consisting of 40 Likert-type items. The data were analyzed using simple linear regression. The regression model was statistically significant, F(1, 78) = 7.313, p = .008, with R = .293 and R² = .086. These findings indicate a statistically significant association between self-concept and prosocial behavior, with self-concept accounting for 8.6% of the variance in students’ prosocial behavior. The remaining 91.4% was associated with other factors not included in the model. The findings highlight self-concept as one relevant psychological factor to consider in guidance and counseling services aimed at strengthening students’ prosocial behavior. Nevertheless, because the study used a cross-sectional design and simple regression, the findings should be interpreted as statistical association/prediction rather than definitive causal evidence.
