“…The second limitation is that the magnitude of the interactions observed was quite modest, as indicated by Figures 4 and 6. However, the difficulty of detecting interaction effects in general, and in nonexperimental field studies in particular, has been well documented in the literature (e.g., Brockner, 1988;Evans, 1985;Jaccard, Helbig, Wan, Gutman, & Kritz-Silverstein, 1990;McClelland & Judd, 1993;Morris, Sherman, & Mansfield, 1986;Zedeck, 1971). According to two reviews (Champoux & Peters, 1987;Chaplin, 1991), survey studies that have detected moderation effects tend to have modest effect sizes similar to ours.…”
