Tina Rosenberg (author of the recently blogged about Join the Club) had two recent opinion pieces in the New York Times in November on how groups play a key role in healthy outcomes.
One “Fixes: For Weight Loss, a Recipe of Teamwork and Trust” (11/15/11) focuses on how patients are much more successful in trying to lose weight when they are in groups.
Another “Fixes: At a Big Church, a Small Group Health Solution”
discusses how Saddleback Church (also featured in Bob Putnam and Lew Feldstein’s Better Together) uses small-groups to encourage more healthy lifestyles of their members.
Tip o’ the hat to Lew Feldstein for these articles.
