Self-Disclosure and Two Kinds of Trust

63 (37 male and 26 female) undergraduate students were Ss in a study of the relationship between two kinds of trust and self-disclosure. As predicted, self-disclosure (Jourard scale) was related to trust as measured with the Prisoners' Dilemma Game, but not to Interpersonal trust, as measured with Rotter's scale. No relationship was found between the Rotter Interpersonal Trust Scale and the Prisoner's Dilemma. In line with previous findings: (a) the Rotter Scale correlated with a self-report trust scale, and (b) the Prisoners' Dilemma with authoritarianism (F scale).
