Final answer:
The first principle of Motivational Interviewing is to Develop discrepancy. It involves encouraging clients to recognize the difference between their behaviors and their goals, which increases their motivation for change.

Step-by-step explanation:
The first principle of Motivational Interviewing (MI) is to Develop discrepancy. This principle involves helping clients see the difference between their current behavior and their broader life values or goals. By recognizing this discrepancy, individuals can become more motivated to make changes. MI is a counseling approach that is client-centered and directive, aiming to enhance motivation to change by helping clients explore and resolve ambivalence toward behavior change.
Developing discrepancy is crucial in MI because it relies on the client's intrinsic motivation rather than outside pressure. It aligns with aspects of self-determination theory, which suggests that autonomy, competence, and relatedness are essential for psychological growth, internalization of motivation, and well-being. The approach promotes a client's autonomy in making decisions while providing support to increase the sense of competence in making desired changes.
