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.

Based on self-determination theory, this study proposes and tests a motivational model of intraindividual changes in teacher burnout (emotional exhaustion, depersonalization, and reduced personal accomplishment). Participants were 806 French-Canadian teachers in public elementary and high schools. Results show that changes in teachers' perceptions of classroom overload and students' disruptive behavior are negatively related to changes in autonomous motivation, which in turn negatively predict changes in emotional exhaustion. Results also indicate that changes in teachers' perceptions of students' disruptive behaviors and school principal's leadership behaviors are related to changes in self-efficacy, which in turn negatively predict changes in three burnout components.

The purpose of this study was to determine the role of passion in teachers' burnout symptoms, work satisfaction, and perceptions of positive student classroom behaviors. The dualistic model of passion (Vallerand et al., 2003) proposes 2 types of passion: harmonious and obsessive. In previous studies, harmonious passion has been shown to lead to adaptive outcomes (e.g., well-being and satisfaction), whereas obsessive passion has been shown to lead to less adaptive outcomes (e.g., shame and negative affect). In this study, 494 teachers completed measures of passion for teaching and various outcomes associated with the teaching profession twice over a 3-month period. Results of a cross-lag model based on structural equation modeling revealed that increases in harmonious passion for teaching predicted increases in work satisfaction and decreases in burnout symptoms over time, while changes in obsessive passion were unrelated to such outcomes. In addition, increases in both harmonious and obsessive passion predicted increases in teacher-perceived adaptive student behaviors over time. Overall, the results of the present study suggest that passion for teaching is an important concept to consider in education.

The authors developed and validated a measure of teachers' motivation toward specific work tasks: The Work Tasks Motivation Scale for Teachers (WTMST). The WTMST is designed to assess five motivational constructs toward six work tasks (e.g., class preparation, teaching). The authors conducted a preliminary (n = 42) and a main study among elementary and high school teachers (n = 609) to develop and validate the scale. Overall, results from the main study reveal that the WTMST is composed of 30 reliable and valid factors reflecting five types of motivation among six work tasks carried out by teachers. Results based on an extension of the multitrait-multimethod approach provide very good support for assessing teachers' motivation toward various work tasks. Support for the invariance of the WTMST over gender and teaching levels was also obtained. Results are discussed in light of self-determination theory and the multitask perspective.
