CHRONIC PAIN
This study has several strengths and limitations. This practice-based study was conducted in accordance with the IMMPACT guidelines, which are strongly recommended for chronic pain research.When compared with standard CBT, the total amount of VR treatment of <5 hours in 4 weeks is rather low. Behavioral therapy is given for a minimum of 6 weeks for 6 to 10 hours in total and is proven to be more effective on pain intensity when used even longer.It is known from a network meta-analysis of psychotherapy studies that a waiting list setting can induce a nocebo effect with larger effect sizes of treatment compared with no treatment groups outside this setting.
