"This book is both timely and relevant, as policy makers and individuals entrusted with the task of developing youth programs struggle with ways in which to promote positive youth development. ... Researchers in behavioral sciences ... and practitioners in guidance and youth developmental programs will find this book to be an extremely valuable reference guide. I highly recommend it as a necessary tool in the continuing effort to ensure that future youth development programs are grounded in evidence-based research." (Michael S. Goldsby, Doody's Book Reviews, March, 2016) "This is a chock-full, scholarly volume that might best be lodged in a research library. Among its greatest assets in addition to some valuable findings is that it includes extensive and valuable reference lists and many useful suggestions for future research, following on the 4-H Study." (Sherry Lynn Hatcher, PsycCRITIQUES, Vol. 61 (3), January, 2016)
