Most halfway houses utilize a behavior modification program known as a __________ system.

The correct answer is a "Levels" system, which is commonly used in halfway houses as part of their behavior modification programs. This type of system typically involves structured phases or levels that residents can progress through based on their behavior and adherence to program rules.

In a Levels system, residents start at a lower level and can earn privileges and additional responsibilities as they demonstrate positive behavior, compliance with the rules, and engage in personal development activities. This system encourages accountability and promotes positive changes by reinforcing desired behaviors through a tangible progression. It helps both staff and residents establish clear expectations and rewards for good behavior, making it an effective tool for rehabilitation and transition back into the community.

The other options do not capture the comprehensive nature of the structured behavior modification approach utilized in halfway houses. “Infraction” refers to a breach of rules or regulations, but it does not relate to a system of positive reinforcement. “Progressive” suggests advancement but lacks the specificity of the structured levels that guide resident behavior. “Intake” refers to the initial assessment and admission process into the facility, rather than an ongoing behavioral modification strategy.
