“…A researcher who is using factor analysis must decide how many common factors or principal components to retain. Making the "correct" decision obviates problems caused by over-extraction and under-extraction (e.g., Comrey, 1978Comrey, , 1988Coovert & McNelis, 1988;Fava & Velicer, 1992). In the group cohesion literature, most researchers have used Cattell's (1966) scree test and/or Kaiser's (1960) eigenvalue greater-than-one rule for deciding the number of dimensions to extract (e.g., Budman et al, 1989;Griffith, 1988;Johnson & Fortman, 1988;Vaitkus & Griffith, 1990).…”
