Examining the Differential Effects of a Universal SEL Curriculum on Student Functioning Through the Dual Continua Model of Mental Health.

Social-emotional learning (SEL) curricula, such as Second Step, are increasingly being adopted and implemented as universal supports in schools in order to prevent social-emotional and behavioral problems and promote wellbeing and success. Notwithstanding the empirical support for SEL as a universal prevention strategy, a closer look at the literature indicates that students display differential responses to SEL based on their behavioral functioning at baseline; those students with the highest need benefit the most from SEL. The primary purpose of this study was to evaluate whether a widely-adopted SEL program produces significant effects for different theoretically-constructed groups of students who are representative of the full spectrum of students in a school.
