“…In 1966, Hall and Van de Castle published The Content Analysis of Dreams, which outlines a thorough coding system with which they investigated 1,000 dreams collected from 200 undergraduates from Case Western Reserve University and Baldwin Wallace College in Cleveland, Ohio, between 1947 and1952. Since that time, the Hall-Van de Castle system has been used to compare groups of various ages, cultural backgrounds, and diagnostic categories, as well as genders (e.g., Coté, Lortie-Lussier, Roy, & De Koninck, 1996;Kane, Mellen, Patten, & Samano, 1993;Krippner, Lenz, Barksdale, & Davidson, 1974;Krippner, Posner, Pomerance, Barksdale, & Fischer, 1974;Krippner, Winkler, Rochlen, & Yashar 1998;Lortie-Lussier, Schwab, & De Koninck, 1985;Rubinstein & Krippner, 1991;Soper, Rosenthal, & Milford, 1994). Reliability, by the method of common agreement, ranges from .60 to .90 for the various categories, a range suitable for most research studies; Van de Castle (1969) has addressed validity concerns.…”
