Pavlovian & Skinnerian theories are cited.

John, a 28-year-old male, is seen in an initial interview at a community mental health clinic. He has been diagnosed as Chronically Mentally Ill. He resides with his mother and grandmother. Both his father and grandfather committed suicide in their early 30's. John is afraid that he is fated to join the male-dominated generational pattern. John is oriented to reality and does not appear to have any disturbances in perception or thought. He does appear to be severely depressed and anxious during the initial interview.

Using the theoretical constructs of behaviorism, how would a Pavlovian and Skinnerian explain John's predicament?  What are some of the shortcomings of their approach?

These ideas are presented.
