Results from two studies conducted among French high school (Study 1; N = 473) and higher education students (Study 2; N = 1143) provided support for the unfulfillment of the needs for autonomy, competence, and relatedness to be modeled as a distinct need state relative to the satisfaction and frustration of those three needs. Results also supported the construct validity of the 35-item PNSE-S in both samples. Moreover, results supported the criterion-related validity of the PNSE-S by indicating that these distinctive need states had well-differentiated effects on a wide array of outcomes of importance for students: feelings of inadequacy, emotional exhaustion, physical fatigue, cognitive weariness, psychological disengagement from distinct targets (other students, teachers and studies), and dropout intentions. This research therefore offers a multidimensional instrument allowing to simultaneously assess students’ need satisfaction, frustration, and unfulfillment. It also shows psychological need unfulfillment to be key in understanding students’ maladaptive functioning. %G English %L hal-04131382 %U https://hal.science/hal-04131382 %~ SHS %~ URCA %~ C2S %~ MSH-URCA
