Review of: "Benefits to Mental Wellbeing from Making Positive Changes in Health-Related Behaviours: An Ultra-Rapid Review"

The topic is important with potentially massive public health implications.Given this, I think it would be more suitable to undertake a more formal and thorough review of the literature, whether of primary literature or of the reviews available.A rapid review and/or umbrella review would be more thorough and suitable to the gravity of the topic.Abstract -there is some description of the method, indicating perhaps an ef cient targeted approach to the literature.Results should include a description of how many reviews or other documents were identi ed, how many were selected, perhaps for each of the main health behaviours in view.
