Jeannie was a delightful little girl who made a remarkable change during adolescence. Her parents expected the usual teenage rebellion, but Jeannie had become dark and morose. Her skin had a deathly pallor, and she became very thin. They feared that she would attempt suicide. They were relieved to find that she suffered a hormone imbalance. Jeannie's diagnosis is based on the:

a. medical perspective.

b. psychoanalytic perspective.

c. behavioral perspective.

d. cognitive perspective.

I think it is a but I am not too sure.

Right.

To determine Jeannie's diagnosis based on the given information, we need to consider the different psychological perspectives and their focuses.

a. The medical perspective: This perspective emphasizes physiological factors and would involve a medical examination to identify any hormone imbalance or other physiological causes for Jeannie's symptoms.

b. The psychoanalytic perspective: This perspective focuses on unconscious conflicts and early childhood experiences. While it could be relevant for understanding mental health issues, the given information does not suggest that Jeannie's symptoms are best explained by this perspective.

c. The behavioral perspective: This perspective emphasizes observable behavior and its association with environmental factors. While it could be relevant for understanding potential changes in Jeannie's behaviors, it does not provide a specific explanation for her symptoms.

d. The cognitive perspective: This perspective focuses on how thoughts, beliefs, and cognitive processes influence behavior and emotions. Jeannie's symptoms, such as her dark and morose attitude, thinness, and deathly pallor, might be explained by distorted or negative thinking patterns.

Considering the given information, the most suitable perspective to explain Jeannie's symptoms is the medical perspective (option a). This implies that a hormone imbalance, which can be identified through medical examination, is the likely cause of her physical and psychological changes.
