The term that best describes the emotional response to a behavior change setback is "discouragement." This emotion typically arises when individuals face challenges or barriers in their efforts to change behavior, leading to feelings of disappointment, frustration, or a lack of motivation to continue making progress.
In the context of behavior change, setbacks can be disheartening, and the emotional response often involves grappling with feelings of doubt or a sense of giving up. Discouragement stems from the perception that progress has stalled or that obstacles are insurmountable, making it a fitting descriptor for the emotional landscape during difficult times in the recovery or change process.
Empowerment, on the other hand, generally refers to feelings of strength and confidence that arise from overcoming challenges, which may not align with the feelings experienced during a setback. Dejection also suggests a sense of hopelessness but lacks the specificity of discouragement as it does not necessarily imply a direct connection to behavior change. Indifference implies a lack of concern or interest, which is not applicable in the context of experiencing a setback that evokes an emotional response.
