This study investigated the effects of trust level and note-taking upon the level of self-disclosure among prisoners. Sixty inmates at a federal prison were administered the Rotter Interpersonal Trust Scale. Next, using a median split, participants were divided into two groups of high and low mistrust. Subjects within each of these groups were then randomly assigned to a high, low, or no note-taking condition. Each prisoner then discussed an intimate topic for thirty minutes. Level of self-disclosure was measured by an abbreviated version of the Rotter Incomplete Sentences Blank. No significant differences were found as a function of trust level or note-taking condition. Some implications for further research are suggested.
