Fixed interval schedule is most effective for maintaining desirable behavior over the long-term. This is because a fixed interval schedule involves rewarding individuals for their behavior only after a fixed period of time has elapsed.

Through this schedule, employees receive reinforcement once a week to motivate them to perform their job duties adequately.
