ENThis study focuses on the construct of global motivation. Vallerand (2000) portrays motivation as a three-level construct, manifesting at the global, life domains, and situational levels. Contrary to context-specific motivation, global motivation is described as a general tendency to base one’s actions on intrinsic/extrinsic motives. This hierarchical model of motivation is grounded on Self-Determination Theory (Deci & Ryan, 2000), which suggests that motivation to undertake certain activities ranges from externally controlled to self-determined and, thus, may be placed on the external-internal motivation continuum. This study aimed to test the psychometric properties of the Lithuanian version of the Global Motivation scale (GMS-28; Guay, Mageau & Vallerand, 2003). It has seven subscales and is designed to measure global motivational orientations. Moreover, it can be used as a basis when developing other contextspecific motivation measures. The sample for this study was drawn from the Lithuanian population (N=382). In order to test scale factorial validity, four alternative models were built. Confirmatory factor analysis has shown that a slightly modified 7-factor model fits the data best (RMSEA=.06; CFI=.90; TLI=.88). Item analysis has revealed that all items have high loadings (>.40) in their factors; moreover, adequate item-total correlations were obtained. Finally, scale internal consistency analysis has shown all the subscales to have acceptable reliability coefficients. Based on these results it is concluded that the Lithuanian version of the scale is suitable for use in further Lithuanian studies. [From the publication]
