Self-determination can support student mental health, particularly related to internalizing behaviors, because self-determined actions enable self-motivating consequences (i.e., self-efficacy). Self-regulation--a subset of self-determination--is often utilized by interventionists to improve self-determination and student behavior. Self-regulation interventions often include instruction and opportunities to practice goal setting, self-monitoring, and self-evaluation. However, most behavioral self-regulation interventions tend to be adult rather than self-directed (Estrapala et al., 2021), which limits the opportunities for students to practice informed decision-making, problem-solving, and self-advocacy. Involving students in decision-making is essential to promote overall self-determination development. This article provides specific strategies for teachers, school psychologists, counselors, and other school personnel to increase student involvement in self-regulation intervention planning and implementation. The authors describe embedding student voice into intervention design decisions, using a fictionalized case study.
