Chapter 23: Practicing Psychology in Correctional Settings

The text then evaluates three competing theoretical explanations for how incarceration affects offender conduct. Deterrence theory, which proposes that harsh prison conditions suppress future criminality, is presented as empirically unsuccessful, with research demonstrating that imprisonment fails to reduce crime and typically increases recidivism rates. The prisonization perspective argues that prisons function as criminogenic environments where low-risk individuals acquire antisocial behaviors through peer influence, a mechanism most pronounced among lower-risk populations. Behavioral importation theory suggests that inmates' conduct primarily reflects pre-incarceration experiences and coping patterns, with longitudinal evidence showing minimal psychological deterioration attributable exclusively to confinement, though negative institutional climates and overcrowding do create harm. The chapter emphasizes that achieving dual correctional objectives—maintaining institutional safety and reducing public risk upon release—requires adherence to the Risk-Need-Responsivity model, an empirically validated framework demonstrating superior outcomes in recidivism reduction compared to punitive approaches. Critical applications include cognitive-behavioral interventions and token economy systems for managing institutional misconduct, with the Risk Principle demonstrating that high-risk offenders benefit from intensive treatment while low-risk individuals experience iatrogenic effects when subjected to such programming. The chapter addresses administrative segregation, acknowledging the prevailing assumption that solitary confinement causes psychological harm while presenting emerging longitudinal evidence suggesting heterogeneous outcomes, and recommends vulnerability assessments and risk-based deflection strategies as alternatives. Throughout, the chapter cautions against correctional quackery—interventions grounded in intuition rather than empirical validation—advocating for sustained commitment to evidence-based psychological science in custodial settings.
