The study investigated the effects of locus of control beliefs as an individual difference variable on (a) the relationship between negative life events and psychological disorder, (b) perceptions of control over negative life events, and (c) the receipt and impact of social support. Ninety-three college undergraduates (52 internals, 41 externals) reported the negative events which occurred to them in the past year, their perceived control over these events, the amount of socially supportive transactions they received, and their psychological symptomatology (anxiety and depression). The correlation between negative events and anxiety was greater for externals than for internals. However, locus of control did not effect ratings of control over negative events or the correlations between high and low control negative events and psychological disorder. Locus of control did effect the receipt and impact of social support. Externality was positively related to the quantity of support received (r(90) = .21, p less than .05) but the stress-buffering effect of support was obtained for internals and not externals. Implications of the results from understanding the process by which locus of control moderates the effects of stress are discussed.
