Case Study
A 26 year old man has started to count in units of 4. As he walks he counts his steps, one two three, four. As he shops he counts items on the shelves, one, two, three, four. He has taken to insisting that when his wife and he kiss, that they kiss four times or a multiple of four times. He and his wife come to visit your for help. Both of them realize this behavior is irrational. How do your further this diagnosis?

Case Study
A 47 year old female client tells you that as a child she grew up on a farm. Her father would discipline her by humiliating her by calling her names, such as “stupid, and lazy”. For punishment, he would take her outside of the house and threaten her with a gun and then shoot the gun off near her. She was terrified that one day her could kill her. She has recently married for the second time to a “very nice man”; however, she has many flashbacks to her childhood, nightmares, and is suspicious of her husband. What is this client’s diagnosis and prognosis?
