Thanks for your question, Liz. The Lifestyle Criminality Screening Form (LCSF) was published in 1991 by G. D. Walters, T. W. White, and D. Denney after sampling inmates in a maximum security federal prison. It measures the likelihood of future criminal behavior by assessing four primary domains: irresponsibility, self-indulgence, interpersonal intrusiveness, and social rule breaking. Results of the assessment are used to manage inmate populations and to group them according to their risk profile.
