Behavioral ActivationAn Everyday Insight tool

The research

Where behavioral activation comes from, what the studies have found, and the sources behind each part of Behavioral Activation. They’re named as background and further reading. None of their authors reviewed or endorse this tool.

Where it comes from

Behavioral activation grew out of Peter Lewinsohn’s work in the 1970s on depression and reinforcement. When fewer things in a day bring enjoyment or a sense of getting something done, people tend to do less, and doing less leaves even fewer of those moments. In 1996, Neil Jacobson and colleagues compared the full package of cognitive therapy with its activation part alone and found that the activation part did about as well. Behavioral activation became a treatment of its own after that.

Two manuals are in wide use today. Christopher Martell, Sona Dimidjian, and Ruth Herman-Dunn’s Behavioral Activation for Depression, in its second edition from 2021, works through activity monitoring, scheduling, graded tasks, avoidance patterns, rumination, and routines. Its approach to avoidance goes back to Martell, Addis, and Jacobson’s Depression in Context in 2001. The brief behavioral activation treatment by Carl Lejuez and colleagues, revised in 2011, is shorter. It asks about values in five areas of life, chooses activities that fit them, ranks those activities from easiest to hardest, and plans them day by day, starting with the easiest.

Behavioral Activation draws on both. Its screens, printables, and wording were written for Everyday Insight, and it doesn’t reproduce either manual’s forms.

What the studies have found

The largest review so far, by Pim Cuijpers and colleagues in 2026, pooled 105 randomized trials with about 13,900 people. For adult outpatients, behavioral activation did better than control conditions, with a standardized mean difference of 0.67, and the difference was still there 12 months later. It did no differently from other psychotherapies. Self-guided behavioral activation, the format closest to a planner like this one, had a smaller effect of 0.36.

In the COBRA trial in 2016, behavioral activation delivered by junior mental health workers did no worse than cognitive behavioral therapy delivered by therapists, at lower cost. In an earlier trial by Sona Dimidjian and colleagues in 2006, behavioral activation did about as well as antidepressant medication for people with more severe depression, and better than cognitive therapy in that group.

Reviews of behavioral activation delivered online or through apps, in 2018, 2023, and 2025, found benefits in the short term. The newest found them fading by 12 months, and keeping people engaged is the weak point across these studies. Moodivate, a brief behavioral activation app from the Medical University of South Carolina, did better than usual care in a small pilot in primary care, and its Spanish version, ¡Aptívate!, did the same in a pilot with Latinx adults with limited English. A full trial with 649 adults in 22 primary care clinics followed in 2025, and Moodivate again did better than usual care over 12 weeks.

These findings are about behavioral activation as a method, mostly guided by clinicians. They aren’t findings about this planner, which hasn’t been studied.

Values

Both manuals use values, and they make the choice of activities personal. A meta-analysis by Aliza Stein and colleagues in 2021 found no evidence that talking about values added to behavioral activation’s effect on depression. So the planner treats values as an optional way to choose activities that matter, not as an exercise that promises more.

The value words come from the Personal Values Card Sort. Values from the Personal Values Card Sort by W. R. Miller, J. C’de Baca, D. B. Matthews, and P. L. Wilbourne, University of New Mexico, 2001. Public domain. Values Card Sort, another Everyday Insight tool, has the full sort.

In Spanish

Behavioral activation has been tested in Spanish with Latino adults in the United States, by Anahí Collado and colleagues in 2016 and by Jonathan Kanter and colleagues in 2015, and the Behavioral Activation for Depression Scale has a Spanish adaptation, by Jorge Barraca and colleagues in 2011.
