The purpose of this study was to propose and test a motivational model of high school dropout. The model posits that teachers, parents, and the school administration's behaviors toward students influence students' perceptions of competence and autonomy. The less autonomy supportive the social agents' behaviors are, the less positive are students' perceptions of competence and autonomy. In turn, the less positive students' perceptions are, the lower their levels of self-determined school motivation are. Finally, low levels of self-determined motivation lead students to develop intentions to drop out of high school, which are later implemented, leading to actual dropout behavior. This model was tested with high school students (N = 4,537) by means of a prospective design. Results from analyses of variance and a structural equation modeling analysis (with LISREL) were found to support the model for all participants and for each gender separately.

The authors investigated students' profiles regarding autonomous, controlled, and amotivated regulation and tested whether profile groups differed on some academic adjustment outcomes. Studies 1 and 2 performed on high school students revealed 3 profiles: (a) students with high levels of both controlled motivation and amotivation but low levels of autonomous motivation, (b) students with high levels of both controlled and autonomous motivation but low levels of amotivation, and (c) students with moderate levels of both autonomous and controlled motivations but low levels of amotivation. These first 2 studies revealed that students in the high autonomous/high controlled group reported the highest degree of academic adjustment. Study 3 performed on college students revealed 3 profiles: (a) students with high levels of autonomous motivations but low levels of both controlled motivation and amotivation, (b) students with high levels of both autonomous and controlled motivation but low levels of amotivation, and (c) students with low to moderate levels of the various motivational components. Study 3 indicated that students in the autonomous group were more persistent than students in the other groups. Results are discussed in light of self-determination theory (E. L. Deci & R. M. Ryan, 1985).

This study tests theoretical and developmental models of the causal ordering between academic selfconcept and academic achievement in a multicohort-multioccasion design (i.e., 3 age cohorts, each with 3 measurement waves). Participants were students in Grades 2, 3, and 4 from 10 elementary schools. The structural equation model for the total sample supported a reciprocal-effects model, indicating that achievement has an effect on self-concept (skill-development model) and that academic self-concept has an effect on achievement (self-enhancement model). This pattern was replicated in tests of invariance across the 3 age cohorts and did not support the developmental hypothesis that skilldevelopment and self-enhancement models would vary with age. Discussion centers on the theoretical, methodological, and practical implications of the results.

The purpose of the present research was to develop and validate a situational (or state) measure of motivation, the Situational Motivation Scale (SIMS). The SIMS is designed to assess the constructs of intrinsic motivation, identified regulation, external regulation, and amotivation (E. L. Deci & R. M. Ryan, 1985, 1991) in field and laboratory settings. Five studies were conducted to develop and validate the SIMS. Overall, results show that the SIMS is composed of 4 internally consistent factors. The construct validity of the scale is also supported by correlations with other constructs as postulated by current theories. Moreover, the SIMS is responsive to experimental induction as evidenced by data gathered through a laboratory study. In sum, the SIMS represents a brief and versatile self-report measure of situational intrinsic motivation, identified regulation, external regulation, and amotivation.

The passion scale, based on the dualistic model of passion, measures 2 distinct types of passion: Harmonious and obsessive passions are predictive of adaptive and less adaptive outcomes, respectively. In a substantive-methodological synergy, we evaluate the construct validity (factor structure, reliability, convergent and discriminant validity) of Passion Scale responses (N = 3,571). The exploratory structural equation model fit to the data was substantially better than the confirmatory factor analysis solution, and resulted in better differentiated (less correlated) factors. Results from a 13-model taxonomy of measurement invariance supported complete invariance (factor loadings, factor correlations, item uniquenesses, item intercepts, and latent means) over language (French vs. English; the instrument was originally devised in French, then translated into English) and gender. Strong measurement partial invariance over 5 passion activity groups (leisure, sport, social, work, education) indicates that the same set of items is appropriate for assessing passion across a wide variety of activities--a previously untested, implicit assumption that greatly enhances practical utility. Support was found for the convergent and discriminant validity of the harmonious and obsessive passion scales, based on a set of validity correlates: life satisfaction, rumination, conflict, time investment, activity liking and valuation, and perceiving the activity as a passion.
