We investigated how mothers’ parenting behaviors and personal characteristics were related to risk-taking by young children. We tested contrasting predictions from evolutionary and social role theories with the former predicting higher risk-taking by boys compared to girls and the latter predicting that mothers would influence children’s gender role development with risk-taking occurring more in children parented with higher levels of harshness (i.e., authoritarian parenting style). In our study, mothers reported their own gender roles and parenting styles as well as their children’s risk-taking and activities related to gender roles. The results were only partially consistent with the two theories, as the amount of risk-taking by sons and daughters did not differ significantly and risk-taking by daughters, but not sons, was positively related to mothers’ use of the authoritarian parenting style and the girls’ engagement in masculine activities. Risk-taking by sons was not predicted by any combination of mother-related variables. Overall, mothers who were higher in femininity used more authoritative and less authoritarian parenting styles. Theoretical implications as well as implications for predicting and reducing children’s risk-taking are discussed.

1. Introduction

Risk-taking by young children can lead to unintentional injury and, in some cases, hospitalization, permanent disability, and death [16]. Efforts to reduce risk-taking in young children through educational interventions with parents and other caregivers are best served by having a complete understanding of the factors predicting children’s risk-taking behaviors. Prior research indicates that boys typically engage in more physical risk-taking than girls and are at higher risk of injury and death than girls [1, 2, 79]. On the one hand, evolutionary theory explains this sex difference in risk-taking as resulting from differences in biology related to different evolutionary histories for men and women [10, 11]. In contrast, social role theory argues that different socialization experiences of boys and girls in early childhood lead to their developing different gender roles [1214]. It is important to note that biology and social environment are often correlated and that distinct effects of biology and social environment are possible. In the present research, we investigated the extent to which mothers’ behaviors and personal characteristics predict risk-taking by young children.

Theoretical perspectives on young children’s risk-taking can be viewed as reflecting the nature-nurture dichotomy. Advocates of the evolutionary perspective emphasize the role of nature in sex differences in children’s risk-taking, arguing that they are the result of different evolutionary histories of the men and women [10, 11]. Throughout human history, boys and men have typically interacted with same-sex social groups that are organized hierarchically in terms of dominance and have engaged in one-on-one and group-on-group competitiveness that involves risk-taking behaviors. In contrast, in human history, girls and women are believed to have developed primarily dyad relationships involving high levels of emotional support, sharing of problems, and problem solving. In a cross-cultural examination of how boys and girls are trained, Low [15] argued that generally boys were trained to be aggressive and independent, but girls were trained to be obedient and industrious with the training that parents provide to children varying as a function of the type of society. In societies in which women access to more resources, girls receive less training to be obedient. Interestingly, Apicella et al. [16] investigated risk-taking with a modern hunter-gather society using an economic game task and found that boys and men took more risks than girls and women in all age groups with the sex difference in risk-taking increasing with age. These results suggest that the greater risk-taking by boys and men occurs across cultures and is likely to reflect different evolutionary histories for men and women in human history.

Within the framework of evolutionary psychology, parent-child interactions early in life have been recognized as a critical predictor of children’s behaviors during childhood as well as throughout the lifespan [17, 18]. Children who experience more negative relationships with parents in early life and less parental investment are likely to differ from other children. Studies have shown that girls with higher levels of negative parent-child relationships enter puberty earlier [19], engage in more sexual risk-taking [20], adopt short-term rather than long-term mating strategies [21], and give birth to children earlier in life [20] than girls from other types of family environments. Girls who experience positive relationships with parents during early childhood enter puberty later, take fewer sexual risks, and have children later in life [22, 23]. Longitudinal studies in which children’s salivary cortisol was assessed as an indicator of stress showed that adverse home environments were related to abnormal cortisol profiles [2427]. Abnormal cortisol levels were observed for both girls and boys reared in homes with higher levels of instability.

An alternative approach to sex differences in risk-taking and other variables is social role theory, whose proponents argue that sex differences in behavior, which appear to be the result of fixed biological differences between the sexes, instead may be the result of different socialization or nurture experiences [1214]. Different socialization experiences are also viewed as the primary cause of the development of different gender roles in boys and girls. There is ample evidence that parents’ gender roles and parenting behaviors contribute to the family context and together influence children’s gender roles and other personal characteristics [2831]. In terms of gender roles, mothers are expected to show more warmth, nurturing, and active involvement, which is associated with high levels of femininity [30, 32, 33], and expectations for fathers include less involvement in the lives of children than mothers, more dominance, and more aggression than mothers [34], which are characteristics associated with masculinity [33].

With regard to risk-taking, prior research has shown that differences in how parents interact with sons and daughters are related to children’s risk-taking [9, 35, 36]. Research by Little and Wyver [37] showed that parents tend to view physical risk-taking more positively in boys than girls and viewed it as being an unmalleable part of being a boy (see also [3]). They also found that parents tended to view girls’ physical risk-taking as not integral to being a girl and, therefore, malleable (see also [3]). Other researchers have reported that parents interactions with boys and girls regarding risk-taking also differ, with parents instructing girls to refrain from all physical risk-taking and providing guidance for boys regarding how to avoid injury while taking physical risks [8, 38]. Another aspect of the family context that has been found to predict children’s risk-taking is family income; specifically children from lower income homes have been found to take more risks than other children ([31, 39, 40]; Olsen, Bottorff, and Frankish, 2008).

The purpose of the present research was to investigate the extent to which mothers’ personal characteristics and behaviors, specifically mothers’ gender roles and parenting styles, were related to risk-taking by children between the ages of two years and five years. We chose to focus on mothers because prior research has shown that mothers are likely to spend more time with children [32] and that mothers’ parenting beliefs and behaviors predict fathers’ parenting behaviors [41]. Our choice to examine this age range of children stems from the fact that gender-specific behaviors have been shown to emerge by the age of two years and become well established by the age of six years [9, 35]. Relatively few studies have investigated the relationships between mothers’ gender roles, mothers’ parenting behaviors, and their children’s risk-taking behaviors. In a study conducted in France, Granié [9] investigated the relationship between mothers’ gender roles and risk-taking in a sample composed of mostly mothers (i.e., 90% of the sample). The results showed that parents’ gender nonconformity (i.e., higher masculinity in mothers) was related to higher levels of children’s gender nonconformity (i.e., higher masculinity in girls and higher femininity in boys) and higher levels of physical risk-taking in sons and daughters.

In the present research, we reasoned that mothers’ gender roles, specifically the level of femininity/masculinity, would be related to their parenting styles and that each of these mother variables may be related to children’s risk-taking. For example, mothers higher in femininity may be less likely to use the authoritarian parenting style, which includes physical coercion, punishment without explanation or reasoning, and verbal hostility [4246]. Authoritarian parents are less likely to permit children to have input on rules and are more likely to use corporal punishment and/or verbal abuse when children disobey (Smetana, 1995; [43]). In contrast, both the authoritative and permissive parenting styles involve providing warmth and support to children and encouraging children to have input on family decisions [31, 4244]. The authoritative parenting style, unlike the permissive parenting style, involves clear rules for children to follow (Smetana, 1995 [43]). Recent research has shown that college students who perceived their parent to have used more authoritative parenting styles during their childhoods described themselves as more feminine and also indicated that they would prefer to use the authoritative parenting style in the future [30]. Similarly, Kelly and Worell [47] found that femininity in men was related to higher levels of warmth experienced from parents during childhood.

In this paper, we report a study in which mothers of young children between the ages of two years and five years completed questionnaires in which they were asked to report their personal characteristics (e.g., gender roles) and behaviors (i.e., parenting styles) as well as the characteristics of their child (i.e., gender-related activities) and their child’s behavior (i.e., risk-taking). We tested the contrasting predictions of evolutionary and social role theories. In accordance with evolutionary theory, we expected to observe higher levels of risk-taking for boys than for girls. Both theoretical perspectives predict that children will take more risks if they are raised in homes with parenting styles involving more harshness and less warmth (i.e., authoritarian parenting style), which may occur more often with mothers who are more masculine/less feminine. In accordance with social role theory, we expected to find this relationship for both boys and girls.

2. Method

2.1. Participants

Ninety-three mothers participated in the study. Their mean age was 34.29 years (SD = 4.79). In the sample, 95.7% of participants were married; 1.1%, divorced; 2.2%, single and cohabiting with a partner; and 1.1%, single and in a relationship with a partner who did not live in the home. In terms of ethnicity, 90.3% of the sample was Caucasian; 2.2%, Hispanic; 3.2%, Asian; and 3.2%, Native American; and 1.1% belonged to more than one category. In terms of education level, 1.1% had completed high school or had a GED, 9.7% had some college experience, 6.5% had completed a 2-year college degree, 34% had completed a 4-year college degree, 32.3% had completed a master’s degree, 1.1% had completed a professional degree, and 14% had completed a doctoral degree. In the sample, 53.8% of mothers described characteristics and behaviors of a daughter and 46.2% of a son. Only 1.1% of the sample involved a nonbiological mother-child relationship. The average age of daughters was 3.70 years (SD = 1.04), and the average age of sons was 3.28 years (SD = 1.05). In terms of birth order, 22.6% of children were only children, 34.4% of children were first born, 8.6% were middle-born, and 32.3% were last-born children. In terms of family income, 6.5% earned less than $30,000 annually; 18.3% earned between $30,000 and $59,999 annually; 4.3% earned between $60,000 and $69,999 annually; 36.6% earned between $70,000 and $99,999 annually; and 38.7% earned $100,000 or more annually. Mothers reported spending 4.63 hours per day with their child (SD = 3.05). Mothers were asked about whom they relied on most for secondary childcare: 41.9% reported that they relied on their spouse, 8.6% on grandparents; 3.2% on other family members, 1.1% on friends; 3.2% on paid baby sitters; 16.1% on childcare centers, and 25.8% on a combination of individuals or groups.

2.2. Materials

We assessed mothers’ gender roles, parenting styles, their child’s gender roles, and their child’s risk-taking behaviors. We assessed mothers’ gender roles using the 60-item Bem Sex Roles Inventory (BSRI) [33]. Mothers were asked to define how descriptive certain personality attributes applied to them on a 7-point scale (1 = never, 7 = always). Of these attributes, 20 were defined as masculine (i.e., having leadership abilities and ambitious); 20 were used to define femininity (i.e., warm and gentle), and 20 were defined as androgynous (i.e., adaptable and shy). For the three categories, scores were summed across the 20 items. The average femininity score for mothers was 5.00 (SD = 0.71). The average masculinity score for mothers was 5.09 (SD = 0.71). The average androgyny score for mothers was 4.39 (SD = 0.41). In the present research, we observed internal consistency for the three subscales, as reflected in Cronbach’s alphas: masculinity (), femininity (), and androgyny ().

Mothers’ Parenting Styles. We assessed parenting style using the 32-item version of the Parenting Styles and Dimensions Questionnaire (PSDQ) [46], which distinguishes three types of parenting style: authoritative, authoritarian, and permissive. Fifteen questions were designed to measure one’s use of the authoritative parenting style; 12 questions the authoritarian parenting styles; and 5 questions the permissive parenting styles. Respondents responded to questions on a 5-point scale (1 = never, 5 = always). Responses were averaged for each type of parenting style with higher numbers reflecting that the parent frequently engaged in the parenting style. Average score of authoritativeness for mothers in this study was 60.26 (SD = 6.68), authoritarianism was 21.043 (SD = 5.31), and permissiveness was 10.19 (SD = 2.96). In the present research, the following Cronbach’s alphas were observed: authoritative parenting (), authoritarian parenting (), and permissive parenting ().

Child’s Gender Roles. We assessed children’s gender roles in terms of their conformity to gender-specific behavior using the 24-item version of the Preschool Activities Inventory (PSAI) [48]. The PSAI asks about the child’s typical activities, including the types of toys involved in play activities. There are 12 masculine items included in the inventory (e.g., guns and cars) and 12 feminine items (e.g., dolls and tea set). Each item is accompanied by a 5-point scale (0 = never; 4 = very often). Following Golombok and Rust [48], the PSAI score for the child was calculated using the following formula: PSAI = 48.25 + 1.1 (sum of male items − sum of female items). PSAI scores above the median are considered masculine and scores below the median are considered feminine. For this study, the average score for males was 65.70 (SD = 8.70) and the average score for daughters was 37.69 (SD = 12.04). In the present research, the following reliabilities were observed: masculine items () and feminine items ().

Child Risk-Taking. We assessed children’s risk-taking using the 24-item Injury Behavior Checklist (IBC) [49]. Sample items include plays with fire and runs out into the street. Each item was accompanied by a 5-point scale (1 = not at all, 5 = very often/more than once a week). The child’s IBC score was the sum of the scores across all items. Higher scores indicated that the child spent more time participating in activities that could lead to injury. For this study, the average score for sons was 52.56 (SD = 9.68) and the average score for daughters was 51.54 (SD = 11.47). In the present research, we observed high reliability for the scale ().

2.3. Procedure

After obtaining IRB approval, we utilized a snowball sampling method, recruiting mothers in person, with printed flyers at community childcare facilities, and with announcements disseminated through multiple electronic social media sites. All participants completed the measures in the same order: BSRI, PSAI, IBC, PSDQ, and demographics. Mothers reported child variables for just one child. The demographics questionnaire included participant information pertaining to age, sex, and intentional interaction (i.e., number of hours in which parent is actively engaging with the child per day). At the end of the survey, all participants were invited to enter themselves into a lottery drawing for $50.

3. Results

We calculated the key variables from mothers’ responses. These included child risk-taking (i.e., score on the IBC), children’s gender role (i.e., score on the PSAI), mothers’ gender roles (i.e., femininity, masculinity, and androgyny), mothers’ parenting styles (authoritative, authoritarian, and permissive), children’s age, and family income. Table 1 provides a summary of the descriptive statistics for the key variables by sex of the child. Inspection of the variances indicated that the variances for variables may have differed for sons and daughters. We assessed the equality of variances for sons’ and daughters’ scores [50]. We found that the only significant result was for IBC scores. The variances for sons’ and daughters’ IBC scores were not equal, , . A Mann–Whitney test indicated that IBC scores did not differ significantly for sons (Mdn = 52.00) and daughters (Mdn = 48.50), , . Comparisons for other variables revealed that sons were described as engaging in significantly higher numbers of masculine activities than were daughters, as reflected in higher scores on the PSAI, , , . For other variables, sons and daughter did not differ significantly: (a) age, , ; (b) mothers’ levels of femininity, masculinity, and androgyny, , ; (c) mothers’ levels of authoritarian, authoritative, or permissive parenting styles, , ; and (e) family income, , .

Table 1: Descriptive statistics for boys and girls in the study.

We examined the interrelationships among the key variables for sons and daughters in a series of Pearson product-moment correlations. Table 2 displays the summary of correlational results by sex of the child. The results showed that, for both girls and boys, mothers who were higher in femininity used the authoritarian parenting style less frequently (overall , ) and used the authoritative parenting style more frequently (overall , ) than others. For sons, but not daughters, age was related to risk-taking, as older sons took more risks than younger sons. Sons whose mothers reported more frequent use of the authoritative parenting style engaged in more masculine behaviors (as assessed by the PSAI) than others sons. For daughters, but not sons, higher levels of risk-taking were reported for daughters who generally engaged in more masculine behaviors (as assessed by the PSAI) and whose mothers reported using the authoritarian parenting style more often.

Table 2: Summary of correlational analyses for boys and girls.

In order to investigate further the factors that predict risk-taking in sons and daughters, we carried out separate multiple regression analyses in which IBC scores were the dependent variable and authoritarian parenting and PSAI scores were the independent variables. In both analyses, independent variables were entered simultaneously. Table 3 displays a summary of the variables, standard errors, beta values, standardized betas, and from these analyses. For girls, the model was significant, , accounted for 31% of the variance in risk-taking (adjusted ). The results showed that both variables were significant predictors: (a) children’s gender role (as measured by the PSAI) with greater participation in masculine activities related to more risk-taking (, ) and (b) mothers’ authoritarian parenting style with more frequent use of the authoritarian parenting style related to more risk-taking (, ). We confirmed that the variables met collinearity assumptions (VIFs = .96 and Tolerance values = 1.05). For boys, the model was not significant, , . In order to explore whether boys’ risk-taking was predicted by other combinations of variables (e.g., authoritative parenting style and mothers’ femininity), additional multiple regressions models were tested, but none were significant.

4. Discussion

The present research investigated the relationships among mothers’ gender roles, their parenting styles, and their children’s gender roles and risk-taking behavior. The results showed that, for girls, risk-taking was predicted by the mothers’ use of the authoritarian parenting style and girls’ gender roles (as measured by the PSAI). The amount of risk-taking observed for boys and girls did not differ significantly; however, the variance observed in risk-taking scores for girls and boys differed, as the amount of risk-taking varied more among girls than among boys. For boys, risk-taking was not significantly related to any variable or predicted by various combinations of variables. Correlational analyses showed that for both girls and boys greater femininity in mothers was significantly related to mothers using more authoritative parenting behaviors and fewer authoritarian parenting behaviors. For boys, but not girls, we found that mothers’ use of more authoritative parenting behaviors was significantly related to more masculine behaviors in boys.

With regard to the theoretical perspectives discussed earlier, the results are partially consistent with each. In accordance with social role theory, we expected to find that mother variables would predict risk-taking by both girls and boys. However, the present results showed that mothers’ use of the authoritarian parenting style predicted risk-taking in girls only, while the amount of authoritarian parenting reported by mothers did not differ significantly for girls and boys. In accordance with evolutionary theory, we expected to find more risk-taking by boys than girls, but the results showed that there was no significant difference in boys’ and girls’ risk-taking. Both the ranges and standard deviations of boys’ and girls’ risk-taking were similar to the data from the sample for girls having slightly higher variance.

The present study had multiple limitations. Foremost, the present research relied on mothers to report children’s behavior, as has many other prior studies investigating child behavior. Parents rely on memory to provide estimates of how often their child engaged in various behaviors; thus, estimates can be unreliable. In addition, mothers’ responses may have been influenced by social desirability bias, as behaviors perceived as socially undesirable may have been underreported. It is possible that the failure to observe an overall difference in risk-taking by boys and girls was due, as least in part, to the IBC’s [49] scale, which had only 5-points (1 = not at all, 5 = very often/more than once a week). The scale is unable to distinguish between risk-taking that occurs more than once a week from that occurring multiple times a week from that occurring multiple times a day. A final limitation is the fact that majority of mothers in our sample were married, relatively well-educated, and relatively high family income, as the results may not necessarily generalize to other types of populations.

Future research is needed to determine whether the present results will generalize to other types of populations, such as lower income families as well as families headed by single parents. To the extent that it is possible, it would be ideal to obtain objective measures of children’s behaviors in addition to parent report measures. In the event that future studies replicate the relationship that was found between the use of the authoritarian style and risk-taking by girls, educational programs could be developed to raise awareness among parents about the relationship between authoritarian parenting and risk-taking in girls. The effectiveness of such programs in reducing children’s risk-taking would require empirical confirmation. Lastly, future research should examine how individual differences in children’s personality are related to parenting style and how both relate to children’s risk-taking. Although there is a tendency to view the relationship between parenting and the behavior of children as unidirectional with parenting influencing behavior, it is important to stress that, at least in some cases, the relationship may be bidirectional. Parents may adopt different, harsher parenting behaviors for children perceived as particularly difficult. The results of the present study may reflect the fact that when daughters engage in risk-taking, mothers may increase their use of authoritarian parenting strategies more so than they do when sons engage in risk-taking, because risk-taking by girls is viewed as more problematic than risk-taking by sons.

In summary, the present study provided evidence that there are relationships among mothers’ gender roles and parenting styles. Further, the use of the authoritarian parenting style predicted risk-taking for young girls, but not boys. We hope the results provide an impetus for future research that investigates risk-taking in children with the long-term aim of reducing it and the injuries in children that can occur. We believe that, by finding a way to reduce forms of physical risk-taking, we not only will be reducing the child injury or death rates, but also will help alleviate or prevent the emotional or stress experienced by all family members when a child is injured.
