A new measure of motivation toward sport has been developed in French, namely the Echelle de Motivation vis-à-vis les Sports. Two studies were conducted to translate and validate this new measure in English. The Sport Motivation Scale (SMS) consists of seven subscales that measure three types of Intrinsic Motivation (IM; IM to Know, IM to Accomplish Things, and IM to Experience Stimulation), three forms of regulation for Extrinsic Motivation (Identified, Introjected, and External), and Amotivation. The first study confirmed the factor structure of the scale and revealed a satisfactory level of internal consistency. Correlations among the subscales revealed a simplex pattern confirming the self-determination continuum and the construct validity of the scale. Gender differences were similar to those obtained with the French-Canadian version. The more self-determined forms of motivation were associated with more positive responses on related consequences. In a second study, the SMS was administered on two occasions and revealed adequate test-retest reliability.

This paper presents 4 studies which were conducted for the purpose of constructing and validating a new measure of people's motivation for environmental behaviors, namely the Motivation Toward the Environment Scale (MTES). The MTES consists of subscales that measure an individual's level of intrinsic, extrinsic, and a motivation for environmental behaviors. These subscales correspond to the different forms of motivation identified by Deci and Ryan in their self‐determination theory (SDT, 1985, 1991). Results from the first study supported the factor structure of the scale and revealed a satisfactory level of internal consistency. Consistent with the SDT, the more self‐determined forms of motivation were associated with more positive responses on the related variables. Implications for the manner in which the public could be encouraged to do environmental behaviors are discussed.

The purpose of this study was to examine the psychometric properties of a new measure of client motivation for therapy, the Client Motivation for Therapy Scale. This scale is designed to measure client's Intrinsic Motivation, four forms of regulation for Extrinsic Motivation (integrated, identified, introjected, and external regulation), and Amotivation for therapy. These subscales correspond to different forms of motivation identified by Deci and Ryan (1985) and fall along a self-determination continuum. An experimental version of the scale, along with related scales, was distributed to a total sample of 138 clients involved in therapy. The results supported the factor structure of the scale and revealed a satisfactory level of internal consistency. Correlations among the subscales revealed a simplex pattern that, in general, provides support for the self-determination continuum and the construct validity of the scale. Implications for research on client motivation for therapy are discussed.

Individuals' reasons for their lack of motivation toward environmental protective behaviors were proposed: amotivation because of strategy, capacity, effort, and helplessness beliefs. Confirmatory factor analyses and correlations between the four types of amotivation and constructs related to the environment supported the validity of the constructs. A structural model in which helplessness beliefs could be predicted by the other sets of beliefs, and wherein strategy and ability beliefs resulted from effort beliefs, was tested. All estimated parameters were significant, with the exception of one link: amotivation because of effort beliefs did not display a significant relationship with helplessness beliefs. The importance of understanding why individuals may be amotivated and the strategies liable to help reduce their lack of motivation are discussed.
