It is well-known that self-regulation is one of the most prominent factors that influences success in learning. Prior research suggested not only a new method in the measurement but also an intervention to develop it. The main aim of this research introduced online questionnaire and validated it. This questionnaire is part of REDI-Space, a self-regulation website. Self-regulation cannot be seen as a single variable but it correlates with other variables such as emotional support and achievement motivation. Thus, in the development of Indonesian Self-Regulation Scales for Adolescence (ISRSA), researcher determines five variables as its contents. This study focused on the validation of two scales (namely, Emotional Support and Achievement Motivation Scale self-report questionnaire) given to students at one university in their first and second year of studies. Scales consisting of 20-item and 24-item were developed for Emotional Support and Achievement Motivation, respectively. Confirmatory Factor Analysis and test-retest reliability were demonstrated to analyse the data. From a group of numbered participants (N=216), there were strong internal consistency, discriminant validity and construct validity. Further research involving other universities can enrich the data to reach a better generalisation.
