This study describes 6- and 12-month outcomes in a referral cohort with anxiety disorders and identifies treatment and prognostic factors related to these outcomes. Patients were recruited at three general hospital clinics, two psychologist-run clinics, and one psychiatric hospital clinic. Outcomes included severity of symptoms, physical and mental health status, and subjective global change in problem severity. Of 254 patients eligible for follow-up, 165 (65.0%) completed a follow-up questionnaire. Methods of treatment included consultation with return to the primary care physician (38.2%); or continued treatment at the clinic, with medications (16.4%), psychotherapy (22.4%), or both (23.0%). Both severity of symptoms and mental health status improved but remained abnormal at follow-up. In multiple logistic regression, subjective global improvement was related to a diagnosis of panic disorder only, treatment with psychotherapy, and type of referral. Change over time in symptom severity was related to clinic type, and change over time in mental health was related to clinic type and duration of previous treatment.
