 Procedures Eligible VAMC patients will be randomized into one of two treatment conditions: transdiagnostic CBT or BAT. Both treatment conditions will include 12-16 weekly 50-minute individual psychotherapy sessions. The total number of sessions will vary slightly depending on participant needs and progress during therapy, as is common in most CBT approaches to psychotherapy and will serve as a covariate in the outcome analyses. The general format of sessions will involve: 1 brief check-in; 2 review of materials from previous sessions; 3 review of homework assignments; 4 overview of new materials and in-session exercises; and 5 assignment of homework for next session. Attendance and homework completion will be recorded.
