Psychologists are most likely to help diabetic patients through​

A) ​providing them with educational materials.
B) ​regulating their programs of physical activity.
C) ​improving their adherence to treatment regimens.
D) ​teaching them how to self-administer their insulin.

Psychologists can help diabetic patients improve their adherence to treatment regimens by addressing any underlying psychological issues such as depression, anxiety, or stress that may be hindering their ability to follow their treatment plan. They can also provide support and education to help patients manage the challenges of living with diabetes. While they may assist with insulin administration, regulating physical activity, and providing educational materials, improving adherence to treatment regimens is the most likely area where psychologists can help diabetic patients.
