Abstract
This study is embedded in the theoretical framework of the engine model of positive schooling. Accordingly, relations were investigated between students’ endogenous input variables, process variables, and school achievement as an outcome variable. A sample of 300 students completed web-based self-report measures for all key variables. Specific character strengths were substantially positively related to school satisfaction, enjoyment of learning, academic self-efficacy, and/or school achievement. Exploratory mediation analyses supported the basic assumption that processes mediate the relations between character strengths as input variables and school achievement as an outcome variable. The findings underline the benefit of studying inputs, processes, and outcomes simultaneously to better understand the interplay among relevant variables in the context of positive schooling.
