A new study from the Karolinska Institutet shows that patients with obsessive-compulsive disorder who show “sudden gains” during internet CBT treatment yield better treatment effects, comparted to those who did not have sudden gains, or where “gradual gainers”. A sudden gain is a significant, large improvement of the patients’ symptoms that happens during a short period of time. Patients that showed sudden gains had less OCD symptoms by the end of treatment and during long-term follow-up, compared to those without sudden gains.
These results could help researchers and clinicians to make better prognoses of who is likely to benefit from treatment and which patients need more support in order to reach optimal treatment effect.
