Panic Disorder (With or Without Agoraphobia)
Conditions
Brief summary
The efficacy of two forms of psychotherapy with panic disordered patients, a cognitive-behavioral and a psychodynamic one, are compared under two different, randomized conditions: randomization or self-selection. The basic hypotheses are that the efficacy of both treatments is higher and that the efficacy difference is smaller under self-selection than randomized conditions.
Detailed description
After thorough assessment persons with a panic disorder diagnosis are randomly assigned to three arms: one randomization, one self-selection, and one a low-contact waiting list one. In the randomization arm (R) 95 persons are randomly assigned to Panic Control Treatment (PCT) or Panic-Focused Psychodynamic Psychotherapy (PFPP); in the self-selection arm (SS) 95 persons are offered, after adequate information, to choose which of the two they prefer. Twenty-six persons are initially randomized to a three-month waiting list (with sparse contact over telephone), after which they will be re-randomized, either to further randomization (to PCT or PFPP) or to self-selection. The four groups (R/PCT; R/PFPP; SS/PCT; SS/PFPP) will be compared on the basis of intake and repeated outcome/follow-up assessment.
Interventions
Manualized, 13 sessions (60 min, sometimes extended to 90-120) completed in 12-16 weeks. Total duration 840-1080 min.
Manualized, 19-24 sessions (45 min) completed in 12-16 weeks. Total duration 855-1080 min.
Sparse telephone contact during 12 weeks, then re-randomization
