When we feel bad, we often expect our energy, interest, and desire to do anything to return first — and only then do we think we will be able to start going out again, socializing, working, or returning to our usual activities. However, research on behavioral activation suggests that this sequence can also work in reverse: sometimes a small action comes first, and only then does our state gradually begin to change.

In August 2026, the journal Clinical Psychology Review published the largest review to date of research on behavioral activation for depression. The authors combined the results of 105 randomized studies involving almost 14,000 patients.

Behavioral activation is a form of psychotherapy based on gradually bringing back into our lives activities that may be important, useful, or capable of giving us at least a small sense of satisfaction. With depression, these activities usually become fewer and fewer. We meet loved ones less often, abandon familiar routines, move less, and become increasingly distant from what once gave our lives meaning.

This creates a vicious cycle: a difficult emotional state leads us to withdraw from activity, while reduced activity leaves fewer and fewer opportunities to experience interest, pleasure, closeness, or a sense of accomplishment.

Behavioral activation helps us gently break this cycle. It is not about being told to “pull yourself together” or forcing ourselves to return immediately to our former life. Together with a specialist, we identify what truly matters to us, observe the connection between our actions and our mood, and begin with small, manageable steps. For one person, that step may be a short walk; for another, cooking a meal, calling someone close, or returning to an activity they gave up long ago.

The review found that in adults, behavioral activation noticeably reduces symptoms of depression compared with control conditions. On average, its outcomes were no worse than those of other forms of psychotherapy, and the positive effect was still present after 12 months. Self-guided programs without continuous therapist involvement also helped, although their effects were weaker.

At the same time, the results of individual studies varied considerably, and only 40 of the 105 studies were rated as having a low risk of bias. So it cannot be claimed that the method works equally well for everyone. There is also still insufficient evidence about its effectiveness for children and adolescents and about direct comparisons with medication.

The main conclusion of the study is not that people with depression should simply force themselves to be more active. Depression is not laziness or a lack of things to do. But waiting for the moment when energy and motivation return first can sometimes become part of the vicious cycle itself. The first careful step is not always taken because we already feel better. Sometimes it is precisely where improvement begins.
