Reliability and Validity Study of the Mobile Learning Adoption Scale Developed Based on the Diffusion of Innovations Theory

In this study, a mobile learning adoption scale (MLAS) was developed on the basis of Rogers’ (2003) Diffusion
of Innovations Theory. The scale that was developed consists of four sections. These sections are as follows:
Stages in the innovation-decision process, Types of m-learning decision, Innovativeness level and attributes of
m-learning. There is one question at the level of classification regarding the investigated characteristics of the
participants in the first three sections of the scale. The last section of the scale is composed of 18 items and 5
sub-dimensions in the 7-item Likert type. MLAS was developed in three stages. In the first stage, a detailed
review of literature was performed and an item pool was formed. In the second stage, explanatory factor
analysis was performed to determine the factor structure of the scale while confirmatory factor analysis was
performed to test whether the factors formed confirmed the theory or not. In the final stage of the study, the
reliability of the scale was determined through item, test-retest reliability and internal consistency (Cronbach
Alpha) analyses. In conclusion, the scale developed within the scope of this study was shown to yield valid and
reliable scores.
