Objective Theoretical conceptualizations of interpersonal dependency and dependent personality disorder suggest that (a) high levels of dependency in parents may increase risk for perpetration of child abuse and neglect and (b) children who are victimized may show elevated levels of dependency later in life. This study used meta‐analytic techniques to examine these hypothesized links. Method A systematic search of psychological and medical online databases revealed 14 published studies (21 effect sizes) examining the link between parental dependency and perpetration of abuse or neglect (overall N of perpetrators = 1,321), and 14 published studies (25 effect sizes) assessing dependency in victims of child abuse and neglect (overall N of victims = 38,265). Results The dependency–abuse effect size (d) for perpetrators collapsed across all moderating variables was 0.36, which is considered to be in the medium range. The dependency–victimization effect size (d) collapsed across all moderating variables was 0.29, also a medium effect size. Conclusion These results support and extend analyses of the relationship between dependency and child maltreatment, and suggest that dependency may be both a precipitant of child maltreatment and consequence of victimization. Theoretical and clinical implications are discussed, with suggestions for further research outlined.
