Over the past three decades, our understanding of children’s social and cognitive development has experienced dramatic growth. This body of research has highlighted the interconnected roles that child, family, school, and larger sociocultural factors play on development (Bronfenbrenner and Morris
1998; Morrison et al.
2005). One factor that has emerged as an important predictor of children’s healthy development is self-regulation (Blair
2002; Buckner et al.
2009; McClelland et al.
2007). Defined as a set of acquired, intentional skills involved in controlling, directing, and planning one’s cognition, emotions, and behaviors (Schunk and Zimmerman
1997), successful self-regulation is thought to develop from an interaction between biological factors (e.g., temperament) and experiential factors (e.g., early experiences and social interactions) and is argued to be a marker of adaptive development (Morrison et al.
2009).
Considering the fact that self-regulation is viewed as a critical building block for healthy development, it is no surprise that there is a growing body of literature investigating the predictors of self-regulation. By understanding which characteristics are most frequently and most strongly associated with self-regulatory abilities, interventions can be developed to ensure that children at-risk for poor self-regulation receive the support necessary to enhance their regulatory skills. Recent studies have examined a host of biological and experiential factors to determine whether and how they are linked to self-regulation (see Morrison et al.
2009). Frequently included in these investigations are demographic characteristics of the child, parent, or household (e.g., Evans and Rosenbaum
2008; Matthews et al.
2009) as well as parenting factors (e.g., Crossley and Buckner
2011). These demographic and parenting factors correlate with and/or predict self-regulation. Despite this growing body of research that includes several large-sample studies (e.g., NICHD
2003), there is currently no published research utilizing a nationally-representative probability sample of the American population to investigate correlates of self-regulation in young children. We seek to address this gap by using data from a nationally representative survey of English-speaking American parents whose children were between the ages of 8 months and 8 years. The primary benefit associated with using a randomly chosen representative sample is that it provides researchers the opportunity to generalize their findings to the population it represents (Lohr
2010). In this case, it allows us to detail how American children and their parents behave without having to offer many of the normally mentioned caveats regarding selection bias or response bias (Lohr
2010).
Fielded in the spring 2009, our survey addressed a number of topics including family demographics, parenting style, and children’s regulatory skills. The analyses presented here utilized data from 1,141 parents whose children were between the ages of 2 and 7 years (any child who had not yet turned eight was considered eligible) at the time of the survey. We investigate whether select demographic and parenting variables previously associated with self-regulation remain significant correlates of children’s self-regulation. By looking at the role of these variables in concert with one another, we are able to see which variables have the strongest relationships with self-regulation. Such an understanding can offer important directions for future intervention work designed to support the regulatory skills of young children.
Factors Predicting Self-Regulation Among Children
Demographic factors (both child and family variables) and parenting behaviors are key predictors of self-regulation. We briefly detail the relevant findings from each category. Then, based on this review of the literature, we posit the relationship we expect to find in our analyses and ask whether this relationship will remain when controlling for the other demographic and parenting variables in our model.
Utilizing a variety of measurement techniques to assess self-regulation, the consensus from numerous studies is that self-regulatory processes grow stronger with age (e.g., Kopp
1982; Raffaelli et al.
2005; Simonds et al.
2007). These skills emerge early in life and increase in sophistication over time. Many researchers believe that the link between age and self-regulation is due to the maturation of the prefrontal cortex (Bunge and Zelazo
2006; Zelazo and Cunningham
2007) and other brain regions (Diamond
2000; Lewis and Todd
2007) as these areas are primarily responsible for controlling cognition and emotion.
Evidence also indicates that significant regulatory differences exist between the genders (Duckworth and Seligman
2006; Kochanska et al.
2001; Matthews et al.
2009; Ponitz et al.
2008). Young boys experience more difficulty controlling their cognitions and behaviors when compared with young girls. These findings extend across methodologies as differences have been found in both objective measurements and teacher report (Matthews et al.
2009). Recently, researchers have posited that the relationship between gender and self-regulation may be moderated by family income. Entwisle et al. (
2007) found that boys living in low income families performed significantly worse on tests of reading skills than females living in low income families. These gender differences were not found for children from middle income families. Entwisle et al. (
2007) explain that, in low income families, boys are expected to be more interested in rough play and exhibit more extroverted behavior around others while in middle-to-upper income families these expectations do not exist. It is possible that these endorsed and supported stereotypes held by both parents and teachers may contribute to low income boys’ poorly regulated behaviors (Morrison et al.
2009). More research is needed to determine if income does moderate the relationship between gender and self-regulation.
Research on the relationship between child’s race/ethnicity and self-regulatory behaviors remains limited. The available literature indicates that minority status may be a risk factor for lower self-regulation. When controlling for a host of risk variables, Sektnan et al. (
2010) found that being African American was significantly correlated with lower self-regulation in kindergarten. Although these researchers did not find any relationship between Hispanic ethnicity and self-regulation, other researchers have found that children from disadvantaged Hispanic families entered preschool with significantly lower regulatory skills than their peers (Wanless et al. 2007 as cited in Sektnan et al.
2010).
Beyond child level demographic variables, evidence also indicates that family level demographic variables are associated with self-regulation. Children whose parents, particularly mothers, have greater formal education are better able to exhibit self-control in social and school settings. Mothers with lower educational attainment have children who perform worse on tests of self-regulation (Evans and Rosenbaum
2008; Sektnan et al.
2010) while other studies have found that higher educational status for
both parents positively predicted behavioral regulation (McClelland et al.
2007). Children from homes with fewer economic resources are also routinely found to have lower self-regulation skills than their peers from more affluent backgrounds. Evans and Rosenbaum (
2008) found that white children living in low-income households in rural communities had lower self-regulation when compared to their higher income peers. In a longitudinal study with a sample of ethnically diverse children, they found similar effects of income status on self-regulation with additional evidence suggesting that the effect of income on regulation was independent of other important secondary variables (e.g., maternal education, ethnicity, single-parent status, Evans and Rosenbaum
2008). Howse et al. (
2003) found that children from economically disadvantaged backgrounds had lower self-regulation than their more advantaged peers. Sektnan et al. (
2010) similarly found that children with a lower income-to-needs ratio from 1 through 54 months of age had poorer behavioral regulation skills at 54 months even when controlling for other risk variables. They argue that children experiencing risk factors, including socioeconomic hardship, have fewer resources available to promote behavioral regulation and fewer opportunities to practice these skills. Lastly, new research on neural activity also supports the observed relationships between socioeconomic hardship and regulatory behaviors. Researchers have found that financial hardship is associated with alterations in prefrontal cortex functioning and the cognitive processes underlying regulation in children (Kishiyama et al.
2009).
Unlike family income and self-regulation, there is limited empirical research on the relationship between household composition (single vs multi-parent household) and self-regulation. Work by Colman et al. (
2006) found that household composition did not significantly predict self-regulation in middle childhood. Other research (Evans and Rosenbaum
2008) suggests that children from multi-parent homes may have stronger regulatory skills than children from single-parent homes, although this relationship disappeared when controlling for socioeconomic status, suggesting that it is not the number of parents in the household that is important but rather it is the economic stress facing single parents that impacts children’s self-regulation (see also Murry and Brody
1999).
Parent practices and styles have also been shown to influence children’s self-regulation skills, although the evidence on what these relationships looks like is mixed. Several studies have found a positive impact of parental controlling behavior on children’s self-regulation skills (Eiden et al.
2001; Feldman and Klein
2003) while others have found that the children of less controlling parents enjoy more success (Kochanska and Knaack
2003; Stansbury and Zimmerman
1999) particularly when parents work to support their child’s sense of autonomy (Bernier et al.
2010). Here, we investigate the relationship between three parenting styles—authoritative, authoritarian, and permissive (Baumrind
1971)—and children’s self-regulation.
Authoritative parenting is characterized as parenting that focuses on teaching, encouraging exploration, and guiding the child’s behavior (Baumrind
1971). Parents who employ an authoritative parenting style help the child work through stressful situations by talking with the child about their frustrations and encouraging them to solve the problem on their own. Grolnick and Ryan (
1989) found that mother’s authoritative parenting style was positively related to a child’s self-reported self-regulation. Similarly, research by Tudge et al. (
2003) and Crossley and Buckner (
2011) positively linked authoritative parenting style with stronger behavioral regulation. A meta-analysis of 41 studies measuring parenting styles and the self-regulation skills of preschoolers revealed a small but consistent positive effect for authoritative parenting (defined as positive control) on gaining children’s compliance (one domain of self-regulation; Karreman et al.
2006).
Parents who exhibit an authoritarian style of parenting frequently use methods that are more restrictive and controlling of the child’s behavior, sometimes with harsh punishment (Karreman et al.
2006). This style of parenting is hypothesized to constrain the development of self-regulation in children, as it interferes with the child’s own ability to sort through complicated emotional and behavioral situations. In the meta-analysis mentioned above, the researchers found a moderate negative effect for authoritarian parenting style (defined as negative control) on children’s compliance (one domain of self-regulation; Karreman et al.
2006). Crossley and Buckner (
2011) found a similar pattern. Children from low-income families whose parents utilized harsh parenting practices demonstrated weaker regulatory skills.
As opposed to the previous parenting styles discussed above, permissive parenting is marked by the absence of parental control. Parents classified as permissive will avoid punishing their child, will allow certain transgressions to pass, and do not confront their children regarding their behavior (Baumrind
1971). Baumrind (
1967) theorized that these children would have poor impulse control; however, the research on permissive parenting and how it affects self-regulation is virtually non-existent. The lone available study found that parents who were more permissive had children who were more likely to have stronger self-regulation skills (Morris
2003).
Hypotheses and Research Questions
We expect that as child age and parent education increase, children’s self-regulation skills will also be stronger. We expect that being male, a minority, living in a single-parent household or living in a low income home will be associated with poorer self-regulation. Additionally, based on previous research (Entwisle et al.
2007), we ask whether family income differentially impacts the relationship between gender and self-regulation such that male children from low-income families demonstrate greater self-regulatory difficulties.
Research on parenting and children’s self-regulation suggests that parents must undertake a delicate balancing act with their exercise of parental control (Bernier et al.
2010). At the very start of a child’s life, the parent acts as the primary regulator of behavior. As the infant/toddler moves into early childhood, the burden for regulating behavior, emotions, and cognitions falls onto the child. Parents who focus on guiding their child’s budding abilities to regulate themselves rather than stringently dictating or, at the opposite end, leaving the child to manage on their own, have children who are better at self-regulating (Bernier et al.
2010). With this in mind, we expect that parents who exert either an excess of parental control (i.e., authoritarian parents) or lack of parental control (i.e., permissive parents) will have children who demonstrate weaker self-regulation skills. On the other hand, parents who rely on parenting practices that reinforce the child’s sense of autonomy, yet still maintain a consistent parenting presence (i.e., authoritative parents) will have children who demonstrate stronger self-regulatory skills.
In addition to the anticipated directional relationships described above, we seek to determine which independent variables remain significant correlates of self-regulation when all main effects are entered in the model.
