The Efficacy of Metacognitive Therapy: A Systematic Review and Meta-Analysis -Normann & Morina (2018) (Jo Daniels likes it)

yet another psychotherapy:

"A large proportion of the identified studies treated patients suffering from anxiety and depression (see Table 1). There were eight trials on depressive disorders. Of these, seven were on major depressive disorder, whereas one study also included a small proportion of patients with bipolar II and bipolar not-otherwise-specified (Jordan et al., 2014).
Five trials were conducted on generalized anxiety disorder, three were conducted on post-traumatic stress disorder, and three were conducted on transdiagnostic samples with anxiety and/or depression. The remaining six trials were on cancer distress, schizophrenia spectrum disorders, body dysmorphic disorder, hyposexual desire disorder, obsessive-compulsive disorder, and grief."

Risk of bias

"Thus, additional randomized controlled trials with larger sample sizes are needed in order to draw firm conclusions on whether there are differences in treatment effects between MCT and CBT interventions. Furthermore, future research should investigate whether MCT and CBT work differently for different groups of patients with psychological complaints."

eta: I expect we will be seeing trials of this comparing it to CBT(?)

 

They still can't analyse BIAS . 18 out of 25 trials had UNCLEAR risk of selective reporting so they conclude that bias was low in 75%. Surely it was high !

 

The most reproduced and robust scientific finding ever.
