This table describes participant characteristics of interviewees. Hierarchy status refers to the within-prison social hierarchy. These include, in descending order of status: 1) poryadochnyi (“decent one”); 2) neput’ (“one who lost the way”); 3) obizhennyi (“one who has offended”). A person could be promoted or demoted based on various behaviors and interactions with people of different hierarchy statuses [29, 30].
