Individually tailored internet-based treatment for young adults and adults with panic attacks: randomized controlled trial.

Background: Previous studies on Internet-based treatment with minimal therapist guidance have shown promising results for several specific diagnoses.

Objective: To (1) investigate the effects of a tailored, therapist-guided, Internet-based treatment for individuals with reoccurring panic attacks, and (2) to examine whether people in different age groups (18-30 years and 31-45 years) would respond differently to the treatment.

Methods: We recruited 149 participants from an online list of individuals having expressed an interest in Internet treatment.
