Isi artikel

Summated scales are widely used in management research to measure construct such as job satisfaction and organizational commitment. This article suggests that revelle's (1979) coefficient beta, implement in revelle's (1978) ICLUST item - clustering procedure, should be used in conjuction with cronbach's ceofficient alpha measure of internal consistency as criteria for judging the dimensionality and internal homogeneity of summated scales. The approach is demonstrated using the dimensionality and internal homogeneity of summated scales. The approach is demonstrated using ICLUST reanalyses of sample responses to warr's (1990) affective well - being scale and O'Brien, dowling and kabanoff's (1978) job satisfaction scale. Coefficient beta and item clustering are shown to more clearly identify the homogeneity and internal dimensional structure of summated scale constructs than do traditional principal components analyses. Gives these benefits, revelle's approach is a viable alternative methodology for scale construction in management, organizational and cross - cultural contexts especially when researchers need to make defensible choices between using whole scales or subscales.
