“…Compared to the large number of studies exploring the moderating effect of family variables on the relationship between deviant peer association and delinquency (e.g., Coombs, Paulson, & Richardson, 1991;Farrell, Henry, Mays, & Schoeny, 2011;Galambos, Barker, & Almeida, 2003;Keenan et al, 1995;Lansford et al, 2003;Mason, Cauce, Gonzales, & Hiraga, 1994;Mrug & Windle, 2009;Poole & Regoli, 1979;Trucco, Colder, & Wieczorek, 2011;Vitario, Brendgen, & Tremblay, 2000;Warr, 1993;Zimmerman, Steinman, & Rowe, 1998), few have studied the moderating role of family functioning. Family functioning can be defined as "the quality of family life at the systemic level, such as wellness, competence, strengths, and weaknesses of a family" (Shek, 2005: p. 518).To the knowledge of the investigators, only one study conducted by Henry, Tolan, and Gorman-Smith (2001) adopted a composite score of family relationship (i.e., cohesion, communication, belief about family, shared deviant beliefs, support, and organization) and parenting practices (i.e., positive parenting, discipline effectiveness, discipline avoidance, monitoring/involvement) to investigate four possible models about the relationships among family functioning, peers and delinquency among 246 male adolescents.…”
