Academic motivation in early adolescence based on self-determination theory

Abstract

This paper has tested the most frequently used instrument for assessing academic motivation in adolescents, which measures seven aspects of motivation in accordance with the self-determination theory. In the first version of this questionnaire, four factors were singled out in the Serbian sample. Based on the first version, the second one was made under the name AMS, containing 32 items with five-degree categories of answers ranging from total disagreement to total agreement. The AMS questionnaire was administered on the convenient sample of 1.106 respondents aged 10 to 15 of both genders (51% female). Four factors were extracted, defined as Internal motivation, External motivation, Introjected motivation and Amotivation. The self-determination continuum has not been confirmed completely since some dimensions have a different status of self-determination than it was expected, while psychometric characteristics of the scales proved to be very good. Compared to the first version, this version of the questionnaire has better psychometric characteristics, reflects more clearly the theoretical assumption about the aspects of academic motivation and partially confirms its continuum. Hence, it can be stated that the AMS questionnaire is a good enough indicator of academic motivation in early adolescence.
