This study used a latent difference score growth model to investigate how changes in family structure (biological father and stepfather residence) and maternal employment are associated with American childrenās externalizing problem behaviours (EPB) from ages 4ā10 and whether these associations vary by childrenās level of self-regulation. For all 4-year-old children, living with a biological father at age 4 was associated with reductions in EPB at ages 4ā6 and later years, with no variation by child self-regulation. Living with a stepfather at age 4 was associated with higher levels of EPB at age 4; however, for less-regulated children, stepfather residence at ages 4 and 8 was associated with reductions in EPB between ages 4ā6 and 8ā10, respectively. Greater employment hours were associated with increased EPB in the next 2 years for less-regulated children of all ages; however, except for the age 4ā6 transition, there was a lagged association that reduced behaviour problems after 2 years and outweighed short-term increases.
Research on American school-age children and adolescents shows increased levels of externalizing problem behaviour (EPB) from low levels in the 1970s to high levels in 1999 (Achenbach, Dumenci, & Rescorla, 2003; Collishaw, Gardner, Maughan, Scott, & Pickles, 2012). These rates are alarming, given that EPB is the most common and persistent form of childhood maladjustment with long-term lasting effects (Campbell, 1995; Campbell, Shaw, & Gilliom, 2000). Although the causes of this increase include multiple individual and family-level factors, the centrality of the home in childrenās development is undisputable. The psychological literature has rightly focused on the parentāchild relationship as an important contributor to childrenās behaviour. Other aspects of the home have received less attention in the psychological literature, but have emerged in the sociological literature as important influences on US childrenās development, namely maternal employment and family structure (e.g., father/stepfather residence). Recently, these aspects of family life have undergone dramatic shifts. From the 1970s to 1990s, the labor force participation of married mothers with a preschool age child increased from 37% in 1975 to 62% in 2009 and the proportion of children living with a biological mother and father declined from 77% in 1980 to 59% in 2010 (U.S. Census Bureau, 2012). These family structure changes (e.g., fathers exit or step fathers enter the family) as well as changes in maternal employment are important to consider in understanding changes in childrenās behaviours because they are likely to reduce the amount and quality of time parents have with their children, which may disrupt behaviour especially for children with limited regulatory skills (Bachman, Coley, & Carrano, 2011; Grusec, 2011; Rubin, Burgess, Dwyer, & Hastings, 2003).
Research linking family structure and maternal employment to childrenās EPB is limited in several ways. First, research on maternal employment focuses on the first years of life and pays less attention to the later childhood period (Han, Waldfogel, & Brooks-Gunn, 2001). Second, although research has shown that father residence in early childhood is linked to childrenās adjustment in adolescence (Cabrera, Cook, McFadden, & Bradley, 2012), less is known about how father residence might be linked to childrenās EPB across the early childhood period, especially during transitional periods which represent change and turmoil for some children (Cavanagh & Huston, 2008). Family changes might be especially trying during transitions into middle childhood or adolescence (Bachman et al., 2011; Cavanagh & Huston, 2008). Third, it is unclear how the entry of a stepfather influences childrenās behaviour across early childhood. Fourth, childrenās ability to cope with change in light of their self-regulatory behaviours has not been considered in past research (Cummings, El-Sheikh, Kouros, & Buckhalt, 2009). To address these gaps, we use data from the 1979 National Longitudinal Survey of Youth (NLSY79) (Center for Human Resource Research, 2004) to seek answers for the following questions: (1) are father/stepfather residence, maternal employment and childās self-regulation associated with childrenās EPB at age 4; (2) are father/stepfather residence and maternal employment associated with change in childrenās EPB differently across ages 4ā10 and (3) does the association between father/stepfather residence and maternal employment and change in EPB vary by childrenās level of self-regulation?
CHANGES IN CHILDRENāS EPB
Externalizing behaviours, normative among toddlers, decline with age. As children get older, they are able to regulate their emotions and communicate their feelings with others. By school entry, most children (more than 70% by some national estimates) are age-appropriately compliant, prosocial and cooperative; only a small proportion (12% by some accounts) continues to show antisocial behaviours (NICHD Early Childcare Research Network, 2004).
CONTRIBUTION OF FAMILY STRUCTURE TO CHANGES IN EPB
We frame this paper using resource theory that parents with more resources (e.g., human capital, including education and income) are able to invest more in their children (e.g., providing cognitively stimulating experiences) than those with fewer resources (Haveman & Wolfe, 1994). Thus, children living in two-parent households are likely to have access to more resources, including parental time and stimulating experiences, than those who live with just one parent. Moreover, living in two-parent households with oneās biological father can facilitate fatherāchild interactions, which have been shown to be linked to childrenās social competence (Cabrera, Shannon, & Tamis-LeMonda, 2007; Tamis-LeMonda, Shannon, Cabrera, & Lamb, 2004). Not only are children living with just their mothers less likely to interact with their biological fathers, but they are also more likely to experience a new father figure, which might be beneficial (e.g., bringing additional resources to the household) or detrimental (e.g., creating emotional upheaval) (Amato, 1993).
Research in the last decade has shown that children who grow up living with both parents are less likely to exhibit EPB than children who do not (Hetherington & Stanley-Hagan, 1995; Hofferth, 2006). Magnuson and Berger (2009) found that children living in single-mother and social-father families exhibited increased behaviour problems over time, although another study found this association to be stronger for white than black children (Fomby & Cherlin, 2007). There is also evidence that changes in family structure are positively associated with behavioural problems (Osborne & McLanahan, 2007). Also, a recent study found that compared to children who did not reside with their fathers, children who resided with them in early childhood reported having a better fatherāchild relationship, which was predictive of fewer EPB in adolescence (Cabrera et al., 2012).
However, studies to date have utilized an aggregate measure of father involvementāthe proportion of time in a two biological parent familyāwhich can underestimate the effect because it cannot ascertain that the EPB was related to particular transition of interest (e.g., entry of a stepfather) that may have occurred years before the EPB was assessed (Fomby & Cherlin, 2007; Magnuson & Berger, 2009; Osborne & McLanahan, 2007). Additionally, current methods cannot detect sleeper effects; that is, changes in behaviour may show up several years later. For example, instability in early childhood has been linked with outcomes in middle childhood (Cavanagh & Huston, 2008). In this study, we improve on past studies by including a measure of behaviour soon after the family changes and by examining delayed associations.
CONTRIBUTION OF MATERNAL EMPLOYMENT TO CHANGES IN EPB
Maternal employment can increase resources to the family and reduce maternal stress and hence improve parenting and reduce child EPB. But, it can also reduce the available time mothers have to spend with their children, which may lead to an increase in EPB. Research has shown that maternal employment has a positive influence on childrenās behaviour, but after the childās first year (Han et al., 2001). Because mothers fit their employment around their childās schedule (Sayer, Bianchi, & Robinson, 2004), the income gained may offset much of the potential negative impact on children (Coley et al., 2007). However, older children may demand more time and attention from their parents than younger children, and thus it is possible that maternal employment may influence children differently across the early childhood period. Mothers with long hours of work might be more fatigued and less...
