Kk. Chappell et Cs. Taylor, EVIDENCE FOR THE RELIABILITY AND FACTORIAL VALIDITY OF THE COMPUTER GAME ATTITUDE SCALE, Journal of educational computing research, 17(1), 1997, pp. 67-77
The Computer Game Attitude Scale (CGAS) evaluates student attitudes to
ward educational computer games. This study provides evidence for the
reliability and factorial validity of the scores of the CGAS and its t
wo subscales. Study participants were 186 middle school students from
two large school districts in the Pacific Northwest, one urban and one
suburban. The CGAS produced scores with a total test alpha coefficien
t of .88 for the sample. A principal components factor analysis with a
two factor solution and a varimax rotation was conducted on the items
of the CGAS. Two factors explained 44 percent of the total variance.
The pattern of loadings in the principal components factor analysis su
pports the grouping implied by the two subscales, indicating that the
two subscales were sufficiently stable to be used as separate scores.
Data indicate that the CGAS produced reliable test scores that may aid
researchers, computer game designers, and teachers in the evaluation
of educational software games.
