My strongest reservation about the review concerns the authors’ praise and apparent endorsement of support groups. Far from being "well informed," support groups are often ill informed and heavily biased and provide patients with misinformation. Patient advocacy groups are often vehemently antipsychiatric, and certainly in Canada, some of their members espouse a hostile and malicious attitude toward experts who disagree, not with their symptoms—we fully acknowledge those—but with their etiological theories. The encouragement they provide is often quite detrimental. It is toward a "sick victim" position, rather than toward psychological help and active physical exercise.
