Answer:
self-justification motive
Explanation:
According to my research on studies conducted by various psychotherapists, I can say that based on the information provided within the question the most likely factor would be the self-justification motive. This motive refers to when a person is in a situation in which that individual's behavior is inconsistent with their beliefs, that person tends to justify the behavior and deny any negative feedback associated with the behavior. Therefore Glenda may not admit the negative parts of her behavior, thus exaggerating the effectiveness of her psychotherapy.
