Final answer:
The psychologist's intervention in Marina's case is assertiveness coaching, which helps Marina confidently articulate her health concerns and goals to her doctor.
Step-by-step explanation:
Marina visited a psychologist to receive help with formulating questions for her next doctor's visit. This intervention is focused on helping Marina develop a clear sense of her goals and articulate her concerns and symptoms confidently when speaking with her doctor. The psychologist's role in this instance can be described as performing assertiveness coaching. Assertiveness coaching is a type of intervention where individuals are taught communication strategies to express themselves in a direct and confident manner, which is beneficial in various interpersonal situations, including medical appointments.
Assertiveness coaching would likely involve role-playing scenarios, discussing potential questions and responses, and perhaps therapeutic techniques to manage anxiety. This form of intervention is distinct from the other options given: depersonalization, telemedicine, and motivational interviewing, as it specifically aims to improve an individual's capacity to communicate assertively and effectively.
