Confined inmates experience a multitude of psychological effects, including emotional, cognitive, and psychosis-related symptoms (Smith, 2006; Shalev, 200

. Solitary confinement is considered harmful to the mental health of inmates because it restricts meaningful social contact, a psychological stimulus that humans need in order to remain healthy and functioning (Smith, 2006). Longer stays in solitary confinement are associated with greater mental health symptoms that have serious emotional and behavioral consequences. (Smith, 2006; Shalev, 200

Emotional and behavioral effects of solitary confinement. The majority of those held in solitary confinement experience adverse emotional effects that can range from acute to chronic, depending on the individual and the length of stay in isolation (Shalev, 200

. Confined prisoners also report feelings of panic and rage, including irritability, hostility, and poor impulse control. Additionally, they frequently exhibit symptoms of anxiety that vary from low levels of stress to severe panic attacks. Isolated inmates also experience symptoms of depression, such as hopelessness, mood swings, and withdrawal. These depressive symptoms may even escalate to thoughts of self-harm and suicide. As compared to the general prison population, rates of suicide and self-harm, such as cutting and banging one’s head against the cell wall, are particularly high in prisoners assigned to solitary confinement (Haney, 2003; Shalev, 2008; Greist, 2012).
Many of the issues that confined prisoners have during isolation are also prevalent post-isolation. Those who are isolated also exhibit maladjustment disorders and problems with aggression, both during confinement and afterwards (Briggs et al., 2003). Furthermore, inmates often have difficulty adjusting to social contact post-isolation, and may engage in increased prison misconduct and express hostility towards correctional officers. (Weir, 2012; Dingfelder, 2012; Constanzo, Martinez, Klebe, Torrence & Livengood, 2012). While cases in which inmates have exhibited positive behavioral change after isolation have been documented, such a result is rare (Smith, 2006).
