Cross-sectional studies of attitude-behavior relationships are vulnerable t
o the inflation of correlations by common method variance (CMV). Here. a mo
del is presented that allows partial correlation analysis to adjust the obs
erved correlations for CMV contamination and determine if conclusions about
the and practical significance of a predictor have been influenced by the
presence of CMV. This method also suggests procedures for designing questio
nnaires to increase the precision of this adjustment.
