“…Research that uses locus of control instruments has multiplied during the past two decades. Studies have correlated external locus of control with low socioeconomic status (Coleman, Campbell, Hobson, McPartland, Mood, Weinfeld, & York, 1966), high anxiety (Tolor & Reznikoff, 1967), deviant behavior (Lefcourt, 1966), low achievement motivation (Crandall, Katkovsky, & Crandall, 1965;Crandall, Katkovsky & Preston, 1962), and a predictor of attrition for alcoholism treatment (Walker, Van Ryn, Frederick, Reynolds, & O'Leary, 1980) and weight reduction (Chavez & Michaels, 1980). Further research has correlated high internal locus of control with intellectual intelligence (Swanson, 1980), efficiency (Hersch & Schiebe, 1967), higher school performance (Lao, 1970;McGhee & Crandall, 1968), insight (Tolor & Reznikoff, 1967 and information seeking with regard to health status (Seeman, 1963).…”
