I read a study or an article a few months back that described the efficacy of therapy in terms of years progressed. As in, they asked study participants how many years of growth they had experienced while in therapy. And through this they found some sort of expected ratio like "one year of therapy produces the same amount of personal growth as non-therapy (normal) years" Do you know what this study or article is?
