19. Since I am an existing ASQ:SE user, do I need to purchase the ASQ:SE-2 User’s Guide with the questionnaires, or can I just purchase the updated questionnaires?
While it is recommended that you purchase the ASQ:SE-2 User’s Guide, it is not required. Please note that the User’s Guide describes implementation changes with the new edition, including the need to adjust for prematurity and how questionnaires with missing items are scored.
