Cubic Relations of Autonomous and Controlled Motivation to Achievement: A Cross-National Validation of Self-Determination Theory Using Response Surface Analysis

TL;DR: This study examines the moderating role of teachers' socio-emotional competence on the relationship between academic engagement and autonomous motivation in secondary schools, finding a significant positive correlation and a small moderating effect, suggesting that teacher SEC enhances autonomous motivation.

TL;DR: The aims behind the development of the lavaan package are explained, an overview of its most important features are given, and some examples to illustrate how lavaan works in practice are provided.

TL;DR: In this article, the sensitivity of maximum likelihood (ML), generalized least squares (GLS), and asymptotic distribution-free (ADF)-based fit indices to model misspecification, under conditions that varied sample size and distribution.

TL;DR: In this article, the sensitivity of goodness of fit indexes to lack of measurement invariance at three commonly tested levels: factor loadings, intercepts, and residual variances was examined, and the most intriguing finding was that changes in fit statistics are affected by the interaction between the pattern of invariance and the proportion of invariant items.

TL;DR: The Self-Determination theory as discussed by the authors is a self-motivation theory that focuses on the internalization and differentiation of extrinsic motivation in human beings, and it has been applied in a variety of domains.
