According to the Fogg Method, what is necessary for a behavior change to occur?

The Fogg Behavior Model emphasizes that for a behavior change to take place, three elements must converge: motivation, ability, and a prompt. Among these, feeling motivated and having the capability to perform the behavior are crucial components. If a client lacks motivation, they may not engage in the desired behavior despite having the capability. Conversely, if they are motivated but lack the ability or skills to perform the behavior, they are also unlikely to succeed. Therefore, option B accurately reflects the essence of the Fogg Method, highlighting the importance of both motivation and capability in facilitating effective behavior change.

The other options do not incorporate the complete framework outlined in the Fogg Method. Understanding the task is beneficial, but it does not necessarily drive behavior change on its own. Having a plan can support behavior change, yet without motivation and ability, even the best plans may fall short. Supervision may provide support, but it is not a foundational requirement for behavior change according to the Fogg Method, which centers primarily on internal factors like motivation and capability alongside external prompts.
