 Secondary Aims: 1 Determine if response to laboratory stressors will predict treatment outcome. We hypothesize that those women with the greatest stress response will do worse in treatment and that maintenance on PROG will reduce stressanxiety and thereby improve treatment outcome. 2 Determine if treatment retention is better in the PROG group compared to the PBO group and determine if maintenance on PROG improves overall functioning compared to maintenance on PBO based on the Clinical Global Inventory CGI. We hypothesize that women in the PROG group will have better treatment retention and improvement in CGI scores compared to women in the PBO group.
