The process of change that individuals undergo to improve health and strive for full potential is known as:

The term that describes the process of change individuals undergo to improve their health and strive for their full potential is "recovery." In the context of mental health and substance use, recovery encompasses not just the cessation of substance use or management of a mental health condition but also the overall journey towards a fulfilling and meaningful life. It involves personal growth, self-discovery, and building resilience while enhancing emotional, psychological, and social well-being.

Recovery is a holistic process, emphasizing the importance of hope, empowerment, and personal responsibility. It recognizes that recovery is unique to each individual and may require ongoing support, such as peer support or advocacy, but these are components of the broader recovery journey rather than the essence of the process itself.

Other choices, such as behavioral modification, refer specifically to changing behaviors often without a comprehensive view of the individual's overall recovery journey. Peer support and advocacy are vital methods to facilitate recovery but are not synonymous with the concept of recovery itself. Thus, identifying "recovery" as the answer captures the essence of the transformative journey individuals undertake to reach their full potential.
