Effect of induced elation and depression on internal-external locus of control

This study tested the notion that depression is associated with external locus of control and elation is related to internal locus of control. Temporary mood states (depression, elation, neutral) were produced by means of Velten's auto-suggestion technique. Fifteen female undergraduates were assigned to each mood condition, and locus of control scores were obtained both before and after the mood induction procedure. Pre-post changes were as predicted: elation caused an increased sense of internality, and depression caused an increased sense of externality. Neutral mood induction did not alter locus of control.
