Abstract

Depression is a serious health problem that is paired with significant functional limitations and high social costs. Both cognitive therapy (CT) and interpersonal psychotherapy (IPT) have proven effective in reducing the symptoms associated with depression. Unfortunately, these treatments do not offer sufficient relief for all people with depression, and the risk of relapse is extremely high. Improving these forms of treatment is therefore essential. An important step involves gaining a better understanding of the effects and mechanisms of both treatment interventions. This was the topic of a major treatment study among 182 adults with depression. The research findings reveal that CT and IPT had similarly positive effects on reducing the symptoms of depression and that these effects were greater than those in a control group that placed participants on a waiting list. Unfortunately, the underlying mechanisms of these therapeutic effects remain unclear.
