This study investigated the relationship of self-disclosure and interpersonal solidarity. Major emphasis was devoted to the refinement of a multidimensional measure of reported self-disclosure and development of a preliminary measure of solidarity. Results replicated in two studies indicated that (1) the self-disclosure scales could be improved to acceptable levels of reliability, (2) the solidarity measure validly distinguished between closer and more distant relationships, (3) self-disclosure and solidarity were positively related, and (4) meaningfully higher levels of self-disclosure were associated with high solidarity relations than with low solidarity relations.
