Intra- and interpersonal consequences of experimentally induced concealment

Secrecy, concealment, and thought suppression are assumed to be important aspects of psychopathology. However, most studies address these from an intrapersonal perspective. This study investigates both the intra- as well as the interpersonal consequences of experimentally induced concealment. Two experiments are described in which non-clinical participants were given a concealment instruction (i.e. avoid talking about a certain topic) in a conversation with an interviewer. In the neutral condition there was no such restraint. Interviewees were more tense and more aware during the concealment condition than during the neutral condition, whereas the interviewers were not aware of the participants' avoidance of the concealment topic. The second counterbalanced experiment replicated the results from the initial experiment. The hypotheses were supported that concealment can be induced experimentally leading to thought suppression and elevated levels of discomfort in the concealing individuals, without their conversation partners noticing. Implications for clinical practice are discussed.
