Final answer:
Constructing a decisional balance, involving pros and cons, is a pivotal part of Motivational Interviewing (MI), much like a cost/benefit analysis which assesses marginal costs against marginal benefits.
Step-by-step explanation:
True, constructing a decisional balance, such as weighing the pros and cons, is an essential step of Motivational Interviewing (MI).
In this context, the decisional balance helps individuals evaluate the advantages and disadvantages of making a change. The technique is akin to a cost/benefit analysis, where you compare what you will sacrifice against what you will gain to help make a decision.
Weighing marginal costs—the extra cost of adding an additional unit against marginal benefits—the extra benefit of adding the same unit can be an extremely helpful process in decision-making.
On a T-shaped chart, costs, which include money, effort, and other sacrifices, are on one side, while benefits, which cover money, time, experience, and other improvements gained from a decision, are on the other side.
