What intervention is designed to change behavior using operant and respondent conditioning techniques?

Behavior therapy is designed to change behavior by employing principles of operant and respondent conditioning. Operant conditioning involves modifying behavior through reinforcement or punishment, encouraging the desired behavior while discouraging the undesired one. Respondent conditioning, on the other hand, involves associating a neutral stimulus with an unconditioned stimulus to elicit a conditioned response. By integrating these techniques, behavior therapy aims to create significant changes in an individual's behavior patterns by addressing both learned responses and the ways in which behavior can be influenced through environmental interactions.

The other choices are methods or concepts related to behavioral observation or assessment rather than direct interventions aimed at changing behavior. Antecedents refer to events or stimuli that occur before a behavior and can influence its occurrence, but they do not themselves constitute an intervention. Interval time sampling and duration recording are specific observational strategies used to measure behavior over specified periods, but they do not actively engage in changing behavior.
