A Within-Person Test of the Impact of Extended Solitary Confinement on Mental Health Functioning and Service Use

There is conflicting evidence on whether people, particularly those with preexisting mental health problems, have worse mental health during and after extended solitary confinement (SC) stays. Using administrative data on 843 men, we examined within-person changes in mental health functioning and service use surrounding long-term stays in SC in Florida correctional facilities. During these stays, service use increased, psychological functioning improved, and mental health crises declined. The former two associations persisted during step-down placements in lower levels of restrictive housing and during the month following restrictive housing stays. The same associations were observed among men with and without serious mental illnesses, though they were more muted among the former group. The increased provision of treatment might prevent mental health problems from developing or worsening among those held in long-term SC and might even improve psychological functioning relative to when the same people are in general population housing.
