“…Despite arguments from criminological theory and evidence from qualitative studies that support a crime reducing effect of parenthood, particularly due to a new self-image and cognitive changes (Giordano, Cernkovich, & Rudolph, 2002;Moloney et al, 2009;Shannon & Abrams, 2007), quantitative results are best described as inconclusive. Whereas some studies have found a crime-reducing parenthood effect for men (Kerr et al, 2011;Savolainen, 2009;Zoutewelle-Terovan et al, 2014), other studies have found no effect (Blokland & Nieuwbeerta, 2005;Giordano et al, 2002;Monsbakken, Lyngstad, & Skardhamar, 2013;Warr, 1998) or even a crime-enhancing parenthood effect (Farrington & West, 1995).…”
