“…Outcome evaluation focuses mainly on the results of the programs, whereas process evaluation is concerned with how the program is actually delivered (Dane & Schneider, 1998;Domitrovich & Greenberg, 2000). Process evaluation is widely adopted in prevention science, such as nursing care (Huryk, 2010;Painter et al, 2010), chronic illness prevention programs (Braun et al, 2010;Karwalajtys et al, 2009;Mair, Hiscock, & Beaton, 2008;Shevil & Finlayson, 2009), smoking cessation programs (Gnich, Sheehy, Amos, Bitel, & Platt, 2008;Kwong et al, 2009;Quintiliani, Yang, & Sorensen, 2010), dietary programs (Allicock et al, 2010;Bowes, Marquis, Young, Holowaty, & Issac, 2009;Hart et al, 2009;Muckelbuer, Libuda, Clausen, & Kersting, 2009;Salmela, Poskiparta, Kasila, Vahasarja, & Vanhala, 2009), and AIDS rehabilitation programs (Bertens, Eiling, van den Borne, & Schaalma, 2009;Fraze et al, 2009;Hargreaves et al, 2009;Konle-Parker, Erien, & Dubbert, 2010;Mukoma et al, 2009). In social work practice, process evaluation has been used in family programs (Cohen, Glynn, Hamilton, & Young, 2010;Kumpfer, Pinyuchon, de Melo, & Whiteside, 2008) but is not commonly used in youth programs (Beets et al, 2008;Frazen, Morrel-Samuels, Reischl, & Zimmerman, 2009;Johnson, Lai, Rice, Rose, & Webber, 2010).…”
