What would the diagnosis be for this client?

Roger comes to your office because he has recently been laid off from his job as a store manager. He is concerned because he has started to drink heavily as a result of this and finds himself feeling incredibly sad and depressed. His wife is supportive, but he is afraid she will get tired of dealing with his moods and leave. Although she says she won't, he is becoming preoccupied with the idea of her leaving him. He tells you that his father abused alcohol and that his mother ended up leaving when she couldn't take it any more. His father always drank, according to Roger, would get really down, and, on at least one occasion, talked about suicide. Roger doesn't want to become like his father but finds himself acting in similar ways. He is thinking that maybe he should just tell his wife to leave him, then move to another state, and start all over.

Look at Roger's situation from a psychodynamic, behavioral, and cognitive-behavioral perspective. What in Roger's story would you emphasize from each of these perspectives and how would you treat him according to each perspective?
