Background/Purpose: In an effort to improve academic achievement, researchers and policy makers have advanced social policies designed to promote parental involvement in children’s education. However, nonstandard work schedules (NWS; work schedules outside the typical daytime span) may serve as a barrier to parental involvement and thus a risk factor in children’s academic achievement. The present study investigates how and under what conditions various nonstandard work schedules affect the rate of parental involvement that in turn affects children's (age 13-14) academic achievement. Specifically, this study examines whether two types of parental involvement (at-home involvement and at-school involvement) serve as a mediator. This study also examines whether the effects of NWS on parental involvement and academic achievement vary depending on family structure, with a hypothesis that parental involvement and children's academic achievement will be more adversely affected by parental NWS in single-parent families.

Methods: Data were drawn from the National Longitudinal Survey of Youth 1979 and its Child Supplement. The selected sample included 7,838 children who were followed from birth to age 13 or 14 in 1996-2010. Children's academic achievement was measured by the Peabody Individual Achievement Test (PIAT) reading and math scores. Parental NWS were measured by five categories: 1) standard (if the main job begins at 6 am or later and ends by 6 pm); 2) evening shift (between 2 pm and midnight); 3) night shift (between 9 pm and 6 am); 4) other (split-shift, rotating shift, and irregular hours); and 5) not working. At-school involvement was measured by a composite score of 4 related items (e.g., How often did either of parents attend a school meeting; Cronbach alpha= .60). At-home involvement was measured by a composite score of 6 related items (e.g., how often the child have discussed with their parents school activities, Cronbach alpha=.70). Structural equation modeling (SEM) was used to estimate the relationship among parental NWS, parental involvement, and children's reading and math scores.

The purpose of this study was to examine the cumulative impact of parental nonstandard work schedules (NWS) on adolescent alcohol and cigarette use, with a focus on the mediating role of parent-child communication. Using the National Longitudinal Survey of Youth 1979 and its Child Supplement, our path analyses revealed that (a) parental NWS affected adolescent alcohol and cigarette use via the openness of parent-child communication rather than the frequency of parent-child communication and (b) the pattern and directionality of the mediating effects differed by who worked NWS, when parents worked NWS, and what types of NWS parents worked. Implications and directions for future studies are discussed.

Background and Purpose: This study aims to examine how various forms of family wealth affect college attendance. Family wealth may have an effect on educational attainment over and above the effect of family income that may play a pivotal role in children's future socio-economic status. In light of this, a handful of studies have recently examined the extent to which various forms of wealth (e.g. liquid assets, illiquid assets, and debt) affects post-secondary educational outcomes including college attendance and completion. However, the underlying mechanism that accounts for the relationship still remains unclear. While the borrowing constraint hypothesis considers lack of economic resources to finance college education as a major barrier to college attendance, the ability hypothesis posits that family wealth affects college attendance as it is a crucial determinant of the ability of children to obtain post-secondary education. In other words, whereas the former focuses more on a direct financial effect, the latter emphasizes an indirect effect of family wealth through its impact on the scholastic ability of children. To test these two hypotheses, this study empirically examines a path model in which three forms of family wealth (liquid assets, illiquid assets, and debt) are assumed to have a direct effect on college attendance, and an indirect effect via SAT performance, which is one of the most important criteria in college admission.

Method: We utilize the National Longitudinal Survey of Youth 1997 (NLSY97), which is the only national dataset that provides detailed reliable information on family wealth, SAT score, and college attendance. The study sample drawn from the NLSY97 consists of children who reported that they had taken the SAT between 1996 and 2003 (N=3,216). We construct wealth variables measuring illiquid assets, liquid assets, and debt. For statistical analysis, we use structural equation modeling (SEM) with SAT scores (verbal and math) serving as indicators of scholastic ability. SEM enables us to simultaneously estimate both direct and indirect effects on college attendance. Results: The SEM results support the ability hypothesis rather than the borrowing constraints hypothesis. Although, as expected, the liquid and illiquid assets have a positive effect, the direct effects are not significant. On the other hand, a family wealth measure, liquid assets shows a meaningful, indirect effect on college attendance through SAT (Odds ratio: 1.014, p<.05). Finally, although it is not of primary interest, family income, a traditional way to measure economic resources, is found to have a direct effect on college attendance (Odds ratio: 1.074, p<.05).

Conclusions and implications: This study suggests that family wealth, especially liquid assets which are easily convertible, is important for children's cognitive development, which is a strong predictor of post-secondary education. This finding suggests that it is important to enhance programs designed to encourage poor families to accumulate assets to promote educational achievement of their children. It should also be noted that given the observed direct effect of family income on college attendance, this study does not contradict current policy which helps youth from lower income families finance post-secondary education through borrowing.

Background: With the rise of a 24/7 economy, a growing body of research has examined the impacts of parental shift works, which are especially prevalent among welfare leavers and low-income families, on child development, including cognitive outcomes. Given that parents with shift works may represent distinct groups, it is important to deal with selection bias and/or omitted variable bias in estimating the effects of parental shift works. However, previous empirical studies have often relied on observational data and conventional linear regression, which is unable to control for unmeasured parental characteristics (e.g., parental intelligence). Hence, it is unclear whether their findings reflect causal effects or biased results. In order to address this limitation, we examined the association between parental shift works and children’s cognitive outcomes (under age 5), using a sibling fixed-effects regression (SFE), which helps us make a better causal inference.

Method: Using data from the National Longitudinal Survey of Youth 1979 (NLSY79) and its Child Supplement (NLSY-CS), we pooled 7838 children born to the NLSY female sample. Parental shift work was measured by five categories: 1) day shifts (if the main job begins at 6 am or later and ends by 6 pm); 2) evening shifts (between 2 pm and midnight); 3) night shifts (between 9 pm and 6 am); 4) other shifts (i.e., split-shift, rotating shift, and irregular hours); and 5) not working. Children’s cognitive outcome was measured by the Peabody Picture Vocabulary Test - Revised (PPVT-R). We conducted OLS regression followed by the SFE that regressed differences in sibling PPVT-R scores on differences in siblings’ exposure to parental shift work, differencing out any sibling-invariant characteristics associated with the family, including any unobserved heterogeneity that is constant across siblings within the family.

Results: Our OLS model suggested that paternal night shifts had a negative effect on children’s PPVT-R, while no maternal shift works had significant impacts. Specifically, the PPVT-R score of children with fathers working night shifts was on average about 7 points lower than that of their peers with fathers working standard day shifts (b=-7.36, p<.01), indicating that children with fathers working night shifts fell .35 standard deviation on the PPVT-R scale behind. However, in our SFE model, this negative effect of paternal night shifts dramatically decreased and was not statistically significant (b=-1.88, p>.05), indicating that there was essentially no difference in the PPVT-R between paternal night shifts and standard day shifts.

Implications: Unlike previous studies, our study does not provide empirical evidence that parental shift works have negative effects on children’s cognitive outcomes, suggesting that we should be cautious in making a causal claim from observational data. However, given that the SFE also has limitations, further research is needed to ascertain the causal nature of the intergenerational effects of parental shift works.
