Self-regulation is an individual's influence, orientation, and control over his/her own behaviors. The primary aim of this study was to develop and validate a self-report scale on self-regulation that encompasses both cognitive and motivational factors. The validity and reliability studies of the scale were examined on responses of 872 university students. Exploratory and confirmatory factor analyses confirmed the hypothesized model of self-regulated skills in learning. The scale has 67 items and the factor loadings range from 0.47 to 0.91. The Cronbach's Alpha was computed 0.91 for the whole scale. Discussions and suggestions parallel to findings are given in the end.
