For the purposes of this study, "prisoner" will be defined in accordance with Federal regulations, as "any individual involuntarily confined or detained in a penal institution...[including] individuals sentenced to such an institution under a criminal or civil statute, individuals detained in other facilities by virtue of statutes or commitment procedures which provide alternatives to criminal prosecution or incarceration in a penal institution, and individuals detained pending arraignment, trial, or sentencing…Parolees who are detained in a treatment center as a condition of parole are prisoners; however, persons living in the community and sentenced to community-supervised monitoring, including parolees, are not prisoners." Parolees meeting the definition of prisoner will be ineligible for the study.
