Criminal behavior transmission is strongest from mothers to daughters, then by mothers to sons, fathers to daughters, and fathers to sons

A systematic review and meta-analysis of the intergenerational transmission of criminal behavior. Sytske Besemer et al. Aggression and Violent Behavior, https://doi.org/10.1016/j.avb.2017.10.004

Highlights
•    This meta-analysis synthesized results for around 3 million children.
•    Risk for criminal behavior is roughly 2.4 times higher for kids with criminal parents.
•    Studies considering covariates show the risk to be about 1.8 times higher.
•    Transmission was strongest from mothers to daughters, lowest for fathers to sons.
•    Transmission appeared stronger for cohorts born after 1981.

Abstract: Children whose parents exhibit criminal behavior (CB) appear to have an increased risk of displaying CB themselves. We conducted a systematic review and pooled results from 23 samples in 25 publications (including 3,423,483 children) in this meta-analysis of intergenerational transmission of CB. On average, children with criminal parents were at significantly higher risk for CB compared with children without criminal parents (pooled OR = 2.4). Studies taking into account covariates also showed increased risk for CB (pooled OR = 1.8). Transmission was strongest from mothers to daughters, followed by mothers to sons, fathers to daughters, and fathers to sons. Moreover, transmission appeared stronger for cohorts born after 1981. When we examined methodological quality and other characteristics of studies, response rates, sample size, or use of official records vs. self- or other-reports of parental CB did not moderate outcomes. However, we found stronger transmission for samples that used convenience or case-control sampling, and in studies in which parental CB clearly preceded offspring CB. We discuss mechanisms underlying intergenerational transmission, including social learning, criminogenic environments, biological proneness, and criminal justice bias. Finally, we consider limitations and directions for future research as well as policy implications for breaking the cycle of intergenerational crime.

On why is so strong the transmission mother-daughter: [it] could be that CB is less common for women, so women who engage in such behavior might be more deviant compared with men who engage in CB. This finding would be similar to the gender paradox observed in developmental psychopathology, wherein the gender for which the problem behavior is rarer, compared with the gender in which the problem behavior is more common, displays a more severe form or presentation of the problem behavior (Eme, 1992; Loeber & Keenan, 1994; Wasserman, McReynolds, Ko, Katz, & Carpenter, 2005). Even if mothers’ and fathers’ criminal behavior was not different in terms of its seriousness, it is far rarer for women to be convicted of crime compared with men. Thus, there may be more stigma – both in society in general, as well as in the law enforcement and criminal justice system – for women with histories of CB, who might also be more likely to be labeled as ―disturbed‖ rather than criminal (Hedderman & Gelsthorpe, 1997). Another explanation might be that mothers are more often the main caretakers of their children, such that maternal incarceration following conviction would be significantly more disruptive on children in the home. When fathers are incarcerated, children often stay with their mother; if mothers are incarcerated, children are more likely to move in with other family members or foster parents (Bloom, 1993; Fishman, 1983; Hissel, Bijleveld, & Kruttschnitt, 2011; Myers, Smarsh, Amlund-Hagen, & Kennon, 1999).

Yet another explanation could be that antisocial fathers who are absent might serve as a potential protective factor. Indeed, Jaffee, Moffitt, Caspi, and Taylor (2003) found that when fathers engaged in high levels of CB, the more time they lived with their children, the more problem behavior their children had. Farrington and Crago (2016) also found that intergenerational transmission of crime was stronger when children were not separated from their parents. Of note, previous studies (e.g. Farrington, Barnes, & Lambert, 1996: Rowe & Farrington, 1997) have suggested that intergenerational transmission is stronger for samegender relationships, which was not supported by the findings of the present meta-analysis. On the other hand, we did not find support for our prediction that intergenerational transmission would be stronger, overall, for male than female offspring Although boys are more vulnerable than girls to a host of neurodevelopmental disorders and to the effects of life stressors, it may be the case that, over longer spans of development, both genders are prone to the cascade of effects related to parental CB.
