The presentence investigation is often the first inquiry into the offender's past, and the initial interview provides the framework for the report's description of the offender's history and circumstances. The probation officer inquires about the defendant's family and developmental history, familial and marital relationships, education, employment history, physical and mental health, alcohol or controlled substance abuse, and finances. The emphasis throughout the questioning is on identifying information that is relevant for understanding the defendant's offense conduct and present situation. During the interview, the probation officer will ask the offender to sign authorizations to release confidential information. At the conclusion of the initial interview, the offender may be asked to provide numerous documents to the probation officer substantiating the offender's complete life history. Additionally, the offender may be asked to submit an autobiography.
