The Golden Anniversary Monograph Awards were created to mark NCA’s 50th Anniversary in 1964. Originally, there were awards given to monographs and to books. The book award was deleted and later reinstated as the Diamond Anniversary Book Award. The Golden Anniversary Monograph Awards are presented to the most outstanding scholarly monograph(s) published during the previous calendar year.
My randomized controlled trial published in Social Science & Medicine was honored with the 2015 Golden Anniversary Monograph Award from NCA. You can read more about it here. You can see a list of past award winners here.
