AbstractSchool bonding refers to the connections that students have with their schools and with various aspects of their academic environments, with an emphasis on close affective relationships and investment in doing well at school. The Perception of School Social Bonding (PSSB) instrument is a 10-item, self-report instrument with 3 subscales measuring different aspects of student school bonding: attachment; involvement; and belief. The instrument is grounded in Hirschi’s theory of social control and was evaluated for structural and concurrent validity in a sample of 3,507 students from mixed ethnicity, gender, and age groups. The 3-factor structure of the scale was supported; differences across gender and ethnic groups were identified; and some subscale scores related inversely to chronic school absenteeism. The brevity and sensitivity of the PSSB may make it particularly useful as a universal screening measure in multi-tiered systems of support models.
