The research was conducted on students of SMA Negeri 5 Soppeng with 34 students. The determination of research participants was using the purposive sampling technique. Data were obtained by filling out the Psychological Sense of School Membership (PSSM) scale before and after the gratitude intervention. The validity of the PSSM scale was calculated using the Aiken's V test and obtained a coefficient of 0.88, while the reliability test used Cronbach's Alfa, with a reliability coefficient value of 0.86. The data analysis technique uses the N-Gain score test. The results showed that the average score of sense of school belonging before the intervention was 40.15, while after the intervention it increased to 73.5, the results of the hypothesis test using the difference index (N Gain Score) recorded an increase of 55.9.
