This study examined the clinical effectiveness of CT<jats:italic>v.<\/jats:italic>IPT in a large sample of depressed patients seeking treatment in a Dutch outpatient mental health clinic. We tested whether one of the treatments was superior to the other at post-treatment and at 5 months follow-up. Furthermore, we tested whether active treatment was superior to no treatment. We also assessed whether initial depression severity moderated the effect of time and condition and tested for therapist differences.<\/jats:p><\/jats:sec><jats:sec id=\"S0033291715000033_sec_a2\" sec-type=\"methods\"><jats:title>Method<\/jats:title><jats:p>Depressed adults (<jats:italic>n<\/jats:italic>\u00a0=\u00a0182) were randomized to either CT (<jats:italic>n<\/jats:italic>\u00a0=\u00a076), IPT (<jats:italic>n<\/jats:italic>\u00a0=\u00a075) or a 2-month waiting list control (WLC) condition (<jats:italic>n<\/jats:italic>\u00a0=\u00a031).
