What should I do in the two weeks between sessions?

Short answer

Use the time to practice what your session started. In therapy research this between-session work is called homework, and people who do it tend to do better than people who do not. So keep it simple. Pick one small thing from your session and carry it into your week.

The research
Kazantzis, N., Whittington, C. J., & Dattilio, F. M. (2010). Meta-analysis of homework effects in cognitive and behavioral therapy: A replication and extension. Clinical Psychology: Science and Practice, volume 17, pages 144 to 156.
Sample 46 studies, 1,072 clients in cognitive and behavioral therapy
Published 2010
Journal Clinical Psychology: Science and Practice
Nikolaos Kazantzis and his colleagues pooled 46 studies of cognitive and behavioral therapy, covering 1,072 clients, to test whether between-session homework changes how well therapy works. When they compared the same therapy with and without homework, the versions that included homework came out ahead, with a pooled effect size of about 0.48. That number, called Cohen's d, is a moderate effect, which means a clear and useful difference, not a tiny one and not a miracle. The pattern held up when the authors checked for outliers and for publication bias, and they found no sign that either was driving the result. Their read was steady. Homework was not a minor add-on. It was part of what made the therapy work.

What does this mean for you?

The gap between sessions is not empty time. This research suggests it is part of the treatment. The hour with your therapist opens something up. The days after are where you practice it, and practice is what seems to help it hold.

Be clear about what this study can and cannot say. It looked at cognitive and behavioral therapy, which leans hard on structured between-session tasks, so the finding may not carry over to every kind of care in the same way. It is also older work, and the effect sizes across studies varied. The honest summary is this: doing the between-session work is linked to better results, and in the controlled comparisons it looked like a cause, not just a coincidence. Read it as a strong signal, not a promise about your own path.

What matters for you is the simple part. You do not need a big plan or a perfect routine. The studies counted small, doable tasks: noticing a thought, trying a skill once, writing something down. The point is contact. Staying in touch with the work across the two weeks, even in small ways, tends to beat leaving it all in the therapy room and hoping it keeps.
