Activity Record
Research

What the evidence says

This page summarizes the research behind the activity record for anyone deciding whether it is worth keeping. It covers activity monitoring first, then behavioral activation, the treatment it is most often part of. Every claim below points to a reference in the list at the end. Where the evidence is thin, this page says so.

Where the record comes from

Aaron Beck and colleagues' 1979 manual for cognitive therapy of depression, one of the founding forms of CBT, included a chapter of behavioral techniques. Kanter and colleagues describe it as covering activity monitoring and activity scheduling aimed at mastery and pleasure, and note that simple weekly activity charts first appeared there. Judith Beck's 2020 textbook uses an activity chart with pleasure and mastery ratings in current CBT. Self-help workbooks such as Greenberger and Padesky's Mind Over Mood, in its 2016 second edition, likewise keep an activity record, with one chosen mood rated hour by hour, separate from an activity schedule used for planning.

Behavioral research of the same period linked activity and mood. Peter Lewinsohn and Michael Graf asked 90 people to record their activities and mood for 30 days and reported in 1973 that mood was related to the number of pleasant activities, and that depressed participants took part in fewer. Lewinsohn's group also developed the Pleasant Events Schedule, 320 everyday activities rated for frequency and enjoyment. Douglas MacPhillamy and Lewinsohn published its reliability and validity data in 1982.

Activity monitoring as its own component

Activity monitoring is widely used in CBT, and it is a core part of behavioral activation, a treatment for depression covered further down this page. In 2010 Kanter and colleagues reviewed the techniques used across behavioral activation trials and identified eight, among them activity monitoring, values assessment, activity scheduling, skills training, and procedures targeting avoidance. Monitoring and scheduling appeared in essentially every version. They describe activity monitoring as a form of assessment rather than a behavior change technique, with two main functions: giving a baseline of activity and mood to inform later work, and showing the person that activity and mood are related. They also summarize what Martell and colleagues assess with an activity chart: general activity level, avoidance, the moods that go with different activities, mastery and pleasure, how broad or narrow activity is, and consistency with values. The review also notes that monitoring has been used within cognitive therapy to support work on thoughts.

Why rate by the hour

Asking people about their experience at the moment it happens is an established research method. Csikszentmihalyi and Larson reported the reliability and validity of experience sampling in 1987. Shiffman, Stone and Hufford reviewed ecological momentary assessment, rating experience in the moment during everyday life, in 2008 and set out its advantages, among them reducing the recall bias that affects retrospective reports of mood and behavior. When in-the-moment ratings are missed, a structured reconstruction is a reasonable fallback. Kahneman and colleagues introduced the day reconstruction method in 2004, in which people walk back through the previous day episode by episode. In 909 employed women, its results at the group level corresponded closely with established findings from experience sampling.

The effect of keeping a record

Monitoring a behavior can change it, an effect known as reactivity. Korotitsch and Nelson-Gray reviewed this in 1999 and described the factors that influence whether and how much it happens. Kanter and colleagues cite studies in which activity monitoring alone reduced depressive symptoms or increased activity. They also note that monitoring combined with scheduling did better than monitoring alone, and that many trials have used self-monitoring as the comparison condition for fuller treatments.

Behavioral activation as a treatment

Behavioral activation rests on a behavioral account of depression. Charles Ferster described depression in 1973 partly as a loss of positively reinforced activity. People do less of what once rewarded them, and more of what they do goes to escaping or avoiding things that feel bad. Jacobson and colleagues then tested the pieces of cognitive therapy against each other in 1996. They randomly assigned 150 adults with major depression and found that the behavioral activation component alone did as well as the full treatment at the end of therapy and six months later, and changed negative thinking about as much.

Behavioral activation was then developed as a treatment of its own. Martell, Addis and Jacobson described their version, with its emphasis on avoidance, in 2001. Lejuez, Hopko and colleagues developed a brief version and revised its manual in 2011. Hopko and colleagues compared the main approaches in a 2003 review. Martell, Dimidjian and Herman-Dunn's clinician's guide, in a second edition from 2022, is a practical guide to the treatment.

How well behavioral activation works

Dimidjian and colleagues compared behavioral activation, cognitive therapy, antidepressant medication, and a pill placebo in 241 adults with major depression in 2006. Among the more severely depressed, behavioral activation matched medication and both did better than cognitive therapy.

Three meta-analyses found behavioral activation effective against control conditions. The two that also compared it with cognitive therapy found no meaningful difference. Cognitive therapy includes behavioral steps as well, so these comparisons ask whether a treatment built around behavior does as well as one built mainly around changing thoughts, not whether behavior matters at all. The cognitive comparison treatments also varied across the pooled trials. Cuijpers, van Straten and Warmerdam pooled 16 randomized studies of activity scheduling treatments, their name for behavioral activation, with 780 participants in 2007 and found a large effect against control conditions, and a difference from cognitive therapy close to zero. Mazzucchelli, Kane and Rees pooled 34 studies with 2,055 participants in 2009 and found the same pattern. Ekers and colleagues updated the evidence in 2014 with 26 randomized trials and 1,524 participants, finding behavioral activation superior to control conditions and, in four studies, to antidepressant medication, and noted that study quality was low in most trials and follow-up periods were short.

The COBRA trial, reported by Richards and colleagues in 2016, randomized 440 adults with depression to behavioral activation from junior mental health workers or CBT from qualified therapists. At twelve months behavioral activation was not inferior, and it cost less to deliver. The UK's 2022 guideline on depression in adults includes behavioral activation among its recommended treatments.

Self-guided and online use

Huguet and colleagues reviewed nine randomized trials of internet-delivered behavioral activation with 2,157 adults in 2018. In non-clinical settings, guided programs reduced depression and anxiety more than waitlists and psychoeducation or usual care, and were not inferior to other behavioral therapies or mindfulness. The authors rated much of this evidence as low or very low quality and called for better studies with longer follow-up and in clinical settings.

The UK's 2022 guideline lists guided self-help first among the options for less severe depression. It defines guided self-help as structured materials, which can include behavioral activation, with support from a trained practitioner over about six to eight sessions.

What this does not show

None of the studies above tested this website or this app. They tested the method, mostly delivered or guided by trained people, and mostly for depression. They also tested whole treatments, in which activity monitoring was one part alongside activity scheduling and other techniques. The COBRA trial did not include people who were acutely suicidal or had recently attempted suicide, who were dependent on alcohol or drugs, or who had bipolar disorder or psychosis. Huguet and colleagues note that behavioral activation has begun to gather evidence for problems other than depression, but most of the research still concerns depression. A record can show you a great deal, but it cannot judge whether you need more help or decide what to do next. So these pages suggest support where the research used it, and do not claim a worksheet alone will match the trials.
