As an individual takes concrete steps toward psychotherapy (e.g., attending an intake) and the salience of becoming a help seeker increases, he or she may experience heightened levels of self-stigma and view self-disclosing personal information to a counselor as a risk. There is evidence that eliciting self-affirmation, a psychological process that temporarily bolsters self-worth, can diminish these risks. However, self-affirmation has yet to be tested with individuals who are about to complete an intake assessment, and it is unclear whether it could also impact their expectations about disclosing to a counselor. Thus, the present research utilized a randomized experimental between-subjects design to test the effectiveness of a self-affirmation intervention in reducing self-stigma and improving subsequent expectations of self-disclosing to a counselor in a sample of students about to attend an intake session (N = 124). Results indicated that, compared with a control group, those in the self-affirmation group reported lower self-stigma. Moreover, self-affirmation resulted in a negative indirect effect, through self-stigma, on anticipated risk of disclosure and a positive indirect effect on anticipated benefit of disclosure. Findings suggest that including brief self-affirmation interventions (i.e., in the waiting room) could be one way to reduce self-stigma and increase positive expectations regarding initial intake appointments, which could facilitate a more positive intake experience.
