Foster and adoptive parents often face challenges while taking care of children who, due to their adverse early life experiences, are at risk of developing insecure attachment relationships, behavior problems, and stress dysregulation. Several intervention programs have been developed to help foster and adoptive parents to overcome these challenges. In the current study, a series of eight meta-analyses were performed to examine the effectiveness of these intervention programs on four parent outcomes (sensitive parenting, k = 11, N = 684; dysfunctional discipline, k = 4, N = 239; parenting knowledge and attitudes, k = 7, N = 535; parenting stress, k = 18, N = 1,306), three child outcomes (attachment security, k = 6, N = 395; behavior problems, k = 33, N = 2,661; diurnal cortisol levels, k = 3, N = 261), and placement disruption (k = 7, N = 1,100). Results show positive effects for the four parent outcomes and child behavior problems, but not for attachment security, child diurnal cortisol levels, or placement disruption. Indirect effects on child outcomes may be delayed, and therefore long-term follow-up studies are needed to examine the effects of parenting interventions on children.

Few conditions epitomize severe and chronic stress to a greater extent than child maltreatment, which can derail development across multiple domains of functioning and throughout the life course. Furthermore, child maltreatment tends to co-occur with other adversities, such as poverty. Many individuals grow up under the stressful conditions of these adversities and exhibit developmental competence. The current study prospectively charted the developmental progression of economically disadvantaged maltreated and nonmaltreated children from childhood to emerging adulthood, and examined patterns of competence across multiple developmental domains of functioning central to the period of emerging adulthood. The study investigated childhood precursors to these patterns of adaptation and maladaptation, as well as the physiological cost of these patterns of adaptation (i.e., C-reactive protein; CRP). Latent class analysis revealed four distinct classes of functioning: multifaceted competence across domains (Multifaceted Competence); (multifaceted maladaptation across domains (Multi-Problem); (c) and two classes with mixed patterns of competence and maladaptation (Externalizing Problems and Work/School Impairment). Maltreated individuals were less likely than nonmaltreated individuals to demonstrate patterns of multifaceted competence and more likely to demonstrate aggregate maladaptation across domains. Additionally, Black men who demonstrated a pattern of multifaceted psychosocial competence also evidenced higher levels of low-grade inflammation (indexed by CRP), suggesting physiological distress was associated with adaptation in the context of stress among these individuals. Findings demonstrate the heterogenous patterns of functioning and diverse developmental outcomes that follow early adversity.
