Quizplus · Accepted Answer

Effectiveness refers to the extent to which a specific intervention, procedure, or service produces a beneficial result under ideal conditions.

Effectiveness would be more directly measured by evaluating the outcome or impact of the intervention itself on the client's behavior, regardless of the amount of time spent.
