This article is a contribution to understanding teacher identity related to working with students' psychosocial environment (PSE). A systematic review of quantitative studies (n = 10) analyzing the relations between components of teacher identity and teachers' work with the PSE is presented. Findings indicate significant relations between the identity components task-related self-efficacy and job satisfaction along with likelihood or frequency of intervention in bullying situations. However, results regarding relations between general teaching efficacy or task perception and teachers' approach to bullying were inconclusive. Findings suggest that teachers' self-efficacy and job satisfaction as identity domains play an important role in students' PSE. This information has implications for teacher education, professional development, and policymakers.
