“…This hierarchical rotation procedure (Thompson, 1951; Wallbrown, Blaha, & Wherry, 1973; Wherry, 1959, 1984) has proven useful in the clarification of other complex constructs, such as cognitive abilities (Wallbrown et al, 1973; Wallbrown, Blaha, Wherry, & Counts, 1974), motivation (Kesselman, Hagen, & Wherry, 1974; Wherry & Waters, 1968), work performance (Roach & Wherry, 1970), and coping strategies (Tobin, Holroyd, Reynolds, & Wigal, 1989). This procedure is also similar to other hierarchical rotation procedures (e.g., Hulin, 1982; Parsons & Hulin, 1982; Schmid & Leiman, 1957) and has been recognized as a useful approach to exploratory factor analysis (Gorsuch, 1983, p. 249).…”
