This week I read the new (July) edition of the International Journal of Offender Therapy and Comparative Criminology. Inside was a new outcome study of the Circles of Support and Accountability (CoSA) re-entry program in the South East region of the United Kingdom, by Andrew Bates and colleagues. I consider myself to be a supporter of CoSA and its mission, and I think it’s an excellent program implemented by motivated, diligent, and benevolent individuals. Myself and Ian McPhail have written positively about CoSA on this very blog. Nonetheless, I have constant lingering concerns about the inconvenient truth that, as yet, there is simply not enough evidence to suggest that CoSA programs are effective in their aim to significantly reduce sexual reoffending by Core Members (the individual to whom support and accountability is provided).
