Development and validation of the Gaming Motivation Scale (GAMS)

The purpose of the present research was to develop and validate a measure of gaming motivation. In line with Self-Determination Theory, the Gaming Motivation Scale (GAMS) is designed to assess intrinsic motivation, integrated, identified, introjected, and external regulation, as well as amotivation. Results confirmed the internal consistency of the six subscales. In addition, the six-factor structure of the GAMS was confirmed, as was the presence of a simplex-like structure underlying the GAMS subscales. Finally, the construct validity of the GAMS was supported by correlations with need satisfaction as postulated by Self-Determination Theory. The importance of this new multidimensional scale for the development of research programs on gaming motivation is discussed.
