The link between parental and offspring offending has been well established from some of the earliest longitudinal criminological studies (Glueck & Glueck, 1950). The relationship has been particularly demonstrated for fathers and their offspring (Hjalmarsson & Lindquist, 2012; Rowe & Farrington, 1997; Thornberry, 2009), in part because many of the major cohort studies included only males. Moreover, because the base rate of offending is lower for females, even fewer studies have been able to reliably examine offending and antisocial behavior between mothers and daughters. It is important to determine the nature of the association for females, considering that there are gender differences in the development of antisocial behavior and its associated risk factors (Broidy et al., 2015; Herrera & Stuewig, 2017; Moffitt, Caspi, Rutter, & Silva, 2001). There is also evidence that the needs and profiles of females involved in delinquency and offending are different to that of males and as a result, prevention and rehabilitation programs should be gender-responsive (i.e., developed based on the unique needs of girls) to be effective (Lanctôt, 2018; Matthews & Hubbard, 2008; Wright, Van Voorhis, Salisbury, & Bauman, 2012). Most of the work on the role of gender in prevention programs has focused on adolescence or adulthood, ignoring the earlier developmental periods. One recent study has shown that a childhood (under age 12 years) gender-specific risk assessment tool is effective at predicting offending up to age 21 years (Koegl, Farrington, & Augimeri, 2019). In addition, a review of 50 systematic reviews on developmental prevention programs for individuals, families, and schools concluded that these programs were effective with varying effect sizes (Farrington, Gaffney, Lösel, & Ttofi, 2017). Considering that those individuals who have conduct problems and difficulty regulating their behavior in childhood are more likely to continue offending over the life course (DeLisi & Vaughn, 2014; Moffitt et al., 2001), it would be important from a policy perspective to invest in these early intervention programs. Little research has examined whether females have different needs compared to males in childhood and how this might influence the development of these early intervention programs. This study will investigate the gender differences in the intergenerational transmission of antisocial behavior across three different developmental periods (i.e., early childhood, middle childhood, and early adolescence), which could potentially be targeted for the development of family preventative intervention programs.
