Less Time for Health: Parenting, Work, and Time-Intensive Health Behaviors among Married or Cohabiting Men and Women in the United States.

Time spent working or caring for children may reduce the time available for undertaking time-intensive health behaviors. We test competing perspectives about how work hours and the number of children of specific ages will be associated with married or cohabiting men's and women's sleep duration and physical activity. We use data from the 2004 to 2017 waves of the National Health Interview Survey (N = 154,580). In support of the "time availability" perspective, longer work hours and children of any age are associated with shorter sleep hours. However, in support of the "time deepening" perspective, additional hours of work beyond 40 hours per week and children over the age of five are not associated with reduced physical activity. Contrary to our expectations, we did not find gender differences in support of our theories. Our results suggest that the economy of time works differently for sleep and exercise.

Childhood Family Instability and Young-Adult Union Experiences: Black-White Differences in Outcomes and Effects.

Today's young adults have diverse union experiences; some enter enduring marital or cohabiting unions at young ages, but many delay or dissolve their unions or remain single. Childhood family instability-defined as parents' transitions into or out of romantic coresidential unions-offers one explanation for why some people are more likely than others to enter and exit unions. We evaluate whether this family instability hypothesis-a union-specific version of the general hypothesis that instability affects people across multiple life domains-can explain Black and White young adults' union formation and dissolution. Using data from the Panel Study of Income Dynamics' Transition into Adulthood Supplement (birth cohorts 1989-1999), we find that the marginal effects of childhood family instability on cohabitation and marriage are weaker for Black than for White youth. Further, Black-White differences in childhood family instability's prevalence are small. Consequently, novel decompositions that account for racial differences in instability's prevalence and marginal effects reveal that childhood family instability contributes little to Black-White inequality in young adults' union outcomes. Our results challenge the generalizability of the family instability hypothesis across racialized groups in the union domain. Explanations for Black-White differences in young-adult marriage and cohabitation reside beyond childhood family dynamics.

Income Sources Across Childhood in Families With Nonresident Fathers.

Unpartnered mothers rely on formal and informal income sources to support their coresident minor children. Building on work focusing on selective populations and shorter time horizons, we describe the family income sources on which U.S. women and their minor children rely for up to 17 years following an unpartnered birth or union dissolution (Panel Study of Income Dynamics 2001-2017; N = 12,369 person-year records from 3,148 children). Using rich description and fixed-effect models, we treat family income as dynamic, mapping change in the share and amount of family income from multiple sources as children age and women gain employment experience; enter new unions; experience changes in eligibility for public support programs; and receive contributions from kin, friends, and other household members. A patchwork of income sources is the norm throughout childhood, with mothers' earnings nearly universal but insufficient as a sole source of family income. Maternal repartnering increases family income through new partner earnings but is accompanied by offsetting reductions in other income sources, particularly from outside the household. In the context of weak institutional support for U.S. families, families with nonresident fathers rely on a complex mix of income sources to make ends meet.

Family Socioeconomic Status and Children's Screen Time.

Objective: This mixed-methods study examined whether higher-SES children's digital technology use adhered to contemporaneous pediatric guidelines, how it compared to lower-SES children, and why, as analyses showed, higher-SES children's technology use far exceeded pediatric recommendations. Background: 2013 American Academy of Pediatrics (AAP) guidelines recommended limited "screen time" for children. Higher socioeconomic status (SES) families tend to follow guidelines, but digital technology use-simultaneously a health behavior and a pathway for building human capital-has complex implications. Method: Quantitative analyses provide new nationally representative estimates of the relationship between social class and 9- to 13-year-old children's technology time (including television), device access, and parenting rules (2014 PSID Child Development Supplement, N=427). Qualitative analyses of 77 longitudinal higher-SES parent interviews articulated explanatory processes. Results: Higher-SES children used technology as frequently as others and in excess of recommendations. Their device access, activities, and agency in adhering to rules, however, differed from others. Qualitative analysis uncovered processes that helped explain these findings: parents' ambivalence about technology and perception that expert guidance is absent or unrealistic, and children's exercise of agency to use technology facilitated by "concerted cultivation" parenting styles, led to higher-SES individualistic parenting practices that supported children's increased non-television technology use. Conclusion: Cultures and structures related to children's technology use are in flux, and classed norms and understandings are emerging to construct relevant class-based distinctions around parenting.

Continuity and Change in U.S. Children's Family Composition, 1968-2017.

We document changes in U.S. children's family household composition from 1968 to 2017 with regard to the number and types of kin that children lived with and the frequency of family members' household entrances and departures. Data are from the U.S. Panel Study of Income Dynamics (N = 30,412). Children experienced three decades of increasing instability and diversification in household membership, arriving at a state of "stable complexity" in the most recent decade. Stable complexity is distinguished by a decline in the number of coresident parents; a higher number of stepparents, grandparents, and other relatives in children's households; and less turnover in household membership compared with prior decades, including fewer sibling departures. College-educated households with children were consistently the most stable and least diverse. On several dimensions, household composition has become increasingly similar for non-Hispanic Black and White children. Children in Hispanic households are distinct in having larger family sizes and more expected household entrances and departures by coresident kin.

Interlinking Structural Racism and Heteropatriarchy: Rethinking Family Structure's Effects on Child Outcomes in a Racialized, Unequal Society.

In the field of family science and in the broader family policy discourse, debate is ongoing about the importance of family structure for child outcomes. Missing from this debate is a full integration of how the foundational pillars of White supremacy, namely structural racism and heteropatriarchy, impact both family formation and child outcomes, especially among diversely configured Black families. From a critical intersectional lens, we argue that conceptual models used to explain racialized child outcomes based on family structure effects are problematic because they compare family structure statuses without accounting for structural racism and interlinked heteropatriarchal conditions. We present a new conceptual model that integrates structural racism and heteropatriarchy to examine the salience of family structure statuses for child outcomes and discuss approaches to research design, empirical measurement, and interpretation in order to bring this new model into practice.

Adolescent Technology, Sleep, and Physical Activity Time in Two US Cohorts.

The advent of internet-enabled mobile digital devices has transformed US adolescent technology use over the last decade, yet little is known about how these changes map onto other health-related behaviors. We provide a national profile of how contemporary technology use fits into adolescents' daily health lifestyles compared to the previous generation, with particular attention to whether and for whom technology use displaces time spent in sleep or physical activity. Time diaries were collected from 11-17 year olds in 2002-03 (N=1,139) and 2014-16 (N=527) through the US Panel Study of Income Dynamics Child Development Supplement. Contemporary adolescents spent 40 minutes more per week in technology-focused activities, but their composition was more varied compared to the earlier cohort. Contemporary technology use was predictive of less time in physical activity, and adolescents engaged in frequent video game play spent less time in physical activity compared to peers with other technology use profiles.

Family Complexity and Children's Behavior Problems over Two U.S. Cohorts.

OBJECTIVE: We consider the prevalence of family complexity and its association with children's externalizing behavior problems over children's life course and over historical time. BACKGROUND: A growing literature has demonstrated the prevalence and multidimensional nature of family complexity and its association with child behavior. The nature/strength of this association may have changed in recent cohorts as family complexity has become more common. METHOD: Data are from the 1997 and 2014 cohorts of the Panel Study of Income Dynamics Child Development Supplement. Samples represent U.S. children ages 0-12 years born since 1985 (N=5,030). Ordinary least squares regression estimated change in the association between family complexity and behavior between cohorts. Difference-in-difference models estimated baseline and longitudinal differences in children's behavior as linked to family complexity. RESULTS: The prevalence of family complexity has stabilized over the last two decades, and the antecedents to parental repartnering and complex sibship organization remain similar. The expectation that increasing family complexity contributes to elevated behavior problem scores was not supported. Instead, children who eventually acquired a step- or half-sibling or who experienced parents' union dissolution had elevated behavior problems prior to those changes. CONCLUSION: The prevalence of and precursors to complex family organization were stable across recent child cohorts. The observed association between family complexity and child behavior problems may be attributable to selection mechanisms linked to both parents' family formation trajectories and to children's behavior, rather than to family change itself.

A life course framework for understanding digital technology use in the transition to adulthood.

Rapid increases in young people's time spent using digital technology ("screen time") in the mobile internet era have led to anxiety about long-term effects. This mixed-method US study examines childhood experiences and contextual factors that shape screen time in the transition to adulthood. We recursively analyzed 56 qualitative interviews with young adults in a large metropolitan area in 2016-2018 and prospective longitudinal nationally representative survey data (PSID-CDS-2007 and PSID-TAS-2017) to articulate a conceptual framework of life course influences on young adults' time spent using digital technologies. Inductive qualitative analyses built an initial framework, which was assessed with quantitative data, then further refined with qualitative analyses. Young adults drew on life course perspectives when discussing influences on their current digital technology use. As they suggested, in quantitative analyses more frequent adolescent technology use and greater device access weakly predicted increased technology frequency. Current school enrollment and several current peer factors predicted technology time. Interviewees emphasized the influence of parenting around technology use during adolescence, but parenting did not predict young adult screen time in quantitative analyses. Further qualitative analyses suggested that instead of influencing current technology time, earlier parenting shaped current emotional responses and imagined future technology use. We found young adults' technology use frequency to be informed by earlier experiences but highly malleable. Past technology use and current social contexts matter, but only up to a point. Moving beyond time use to incorporate emotional responses and future plans can better capture how the life course shapes technology use.

The Longitudinal Revolution: Sociological research at the 50-year milestone of the Panel Study of Income Dynamics.

The U.S. Panel Study of Income Dynamics (PSID) celebrated its 50th anniversary in 2018. Initially designed to assess the nation's progress in combatting poverty, PSID's scope broadened quickly to a variety of topics and fields of inquiry. To date, sociologists are the second-most frequent users of PSID data after economists. Here, we describe the ways in which PSID's history reflects shifts in social science scholarship and funding priorities over half a century, take stock of the most important sociological breakthroughs it facilitated, in particular those relying on the longitudinal structure of the data, and critically assess the unique advantages and limitations of the PSID and surveys like it for today's sociological scholarship.

Effects of the COVID-19 crisis on survey fieldwork: Experience and lessons from two major supplements to the U.S. Panel Study of Income Dynamics.

Two major supplements to the Panel Study of Income Dynamics (PSID) were in the field during the COVID-19 outbreak in the United States: the 2019 waves of the PSID Child Development Supplement (CDS-19) and the PSID Transition into Adulthood Supplement (TAS-19). Both CDS-19 and TAS-19 abruptly terminated all face-to-face fieldwork and, for TAS-19, shifted interviewers from working in a centralized call center to working from their homes. Overall, COVID-19 had a net negative effect on response rates in CDS-19 and terminated all home visits that represented an important study component. For TAS-19, the overall effect of Covid-19 was uncertain, but negative. The costs were high of adapting to COVID-19 and providing paid time-off benefits to staff affected by the pandemic. Longitudinal surveys, such as CDS, TAS, and PSID, that span the pandemic will provide valuable information on its life course and intergenerational consequences, making ongoing data collection of vital importance.

Family Systems and Parents' Financial Support for Education in Early Adulthood.

Young adults raised outside of two-parent families receive less financial support from their families for education compared with peers who always lived with both parents. We consider how parents' union status over time shapes contributions for young adult children's education. Our approach emphasizes the dynamic relationship between family structure and family economic resources. Marginal structural models with inverse probability weights estimate the association of parents' union status history with eventual financial transfers while not overcontrolling for the effects of union status operating indirectly through time-varying characteristics, such as coresident family composition and economic circumstances. The analytic sample includes parents of a recent cohort of young adults (Panel Study of Income Dynamics, 1983-2013, N = 2,754). Compared with parents who lived continuously with a child's other parent, unpartnered parents' transfers to children were 44 % to 90 % smaller, and repartnered parents' transfers were one- to two-thirds smaller, depending on how long the parent was unpartnered or repartnered. Through its influence on subsequent coresident family composition and family economic resources, parents' union status has indirect as well as direct associations with financial transfers to adult children for education.

Data Collection on Sensitive Topics with Adolescents Using Interactive Voice Response Technology.

We describe the development and implementation of a survey administered using interactive voice response (IVR) technology to collect information on sensitive topics in a US national sample of adolescents age 12-17. Respondents were participants in the Panel Study of Income Dynamics 2014 Child Development Supplement (N=1,098). We review questionnaire design, fieldwork protocols, data quality and completeness, and respondent burden. We find that in the context of research on sensitive topics with adolescents, IVR is a cost-efficient and flexible method of data collection that yields high survey response rates and low item nonresponse rates with distributions on key variables that are comparable to other national studies.

Family Instability in the Lives of American Children.

Scholars have long looked to family composition to understand child well-being. Family instability, or the experience of repeated changes in parents' union status during childhood, represents a recent advance in this field that takes into account the dynamic nature of contemporary family organization and considers its implications for children's adjustment and development. We review some of the structural and cultural factors that have contributed to rising levels of family instability and highlight the emergence of national data to measure it. We then review the perspective that guides much of the scholarship on family instability and critically assess the contributions of this work to the understanding of child well-being. We close by suggesting new directions for research, with a call for work that broadens the conceptualization and measurement of contemporary children's family systems and home environments as well as the mechanisms that explain why-or whether-instability matters.

Motherhood in Complex Families.

Families formed through multipartner fertility, where children with a common biological mother were conceived by different biological fathers, represent a growing share of all families in the United States. Using data from four waves of the Fragile Families Child and Well-Being Study (N=3,366), I find that women who have engaged in multipartner fertility are more likely to experience parenting stress and depression compared to mothers whose children share the same biological father. Mothers' depression is explained in the short term by poor relationship quality with the father of her prior children and in the longer term by indicators of boundary ambiguity in complex families. Mothers' parenting stress was only weakly explained by variation in perceived kin support, father involvement, or boundary ambiguity.

Family Instability in Childhood and Criminal Offending during the Transition into Adulthood.

The structure and stability of families have long stood as key predictors of juvenile delinquency. Boys from "broken homes" experience a higher prevalence of juvenile delinquency than those from intact families (Rebellon 2002, Wells and Rankin 1991). Unresolved is whether the consequences of frequently disrupted family contexts endure to shape criminal trajectories into adulthood. Long-term influence may also be indirect. Life course criminologists credit family formation during the transition to adulthood, and particularly marriage, for redirecting men's criminal trajectories, but children who experience repeated changes in family structure are more likely to experience precarious starts to their own eventual family formation. Using data from the Panel Study of Income Dynamics and its two child-centered supplemental studies (N=1,127), we find that the experience of repeated family structure change is associated with higher rates of arrest and incarceration during early adulthood for white men but not for black men. This association is partially mediated by a slower transition to marriage among men who experienced three or more changes in family structure during childhood.

Mothers' Time, the Parenting Package, and Links to Healthy Child Development.

Studies consistently show that mothers' time in particular activities with children is positively associated with child well-being, but results are mixed regarding associations between child outcomes and the sheer amount of time that mothers spend with children. Using time diary and survey data from three waves of the Panel Study of Income Dynamics Child Development Supplement (N = 2,622), we assess whether gains from mothers' total time with children vary by the quality of mothers' other investments in children, or the "parenting package." Mother-child shared time was associated with children's broad reading scores and adolescents' externalizing behavior, but mothers' other parenting investments did not moderate these associations. Results were robust to alternative measures of mothers' time and to the incorporation of earlier assessments of child academic and behavior problems. Parenting investments may be indicative of the quality of children's home environments but do not magnify gains from mother-child shared time.

Parents Who Left College and Children's Postsecondary Educational Attainment.

More than one in five US adolescents resides in a household where neither parent holds a postsecondary degree but at least one parent spent some time in college. We consider how a distinctive combination of cultural and economic resources in college leaver families enables or constrains young adults' educational pathways. Greater resources in college leaver families explains about half of the advantage in any college enrollment and four-year college enrollment for young adults in these families compared to those from families where neither parent attended college. But this resource advantage is relatively small compared to families where either parent holds at least a Bachelor's degree, and given any enrollment, children from college leaver families are no more likely to finish college than are their peers whose parents never attended. Results are robust to various specifications of parents' college leaver status. Data are from the Panel Study of Income Dynamics Child Development Supplement and Transition into Adulthood Supplement (N=2,334).

Effectiveness of a Time-Limited Incentive on Participation by Hard-to-Reach Respondents in a Panel Study.

We describe an experiment to provide a time-limited incentive among a random sample of 594 hard-to-reach respondents, 200 of whom were offered the incentive to complete all survey components of a study during a three-week winter holiday period. Sample members were primary caregivers of children included in the 2014 Child Development Supplement to the U.S. Panel Study of Income Dynamics. The incentive provided $50 to caregivers who completed a 75-minute telephone interview and whose eligible children each completed a 30-minute interview. Results indicate that the incentive was an effective and cost-efficient strategy to increase short-term response rates with hard-to-reach respondents with no negative impact on final response rates.

Ecological Instability and Children's Classroom Behavior in Kindergarten.

We engage the concept of ecological instability to assess whether children's exposure to frequent change in multiple contexts is associated with teacher reports of students' overall behavior, externalizing behavior, and approach to learning during kindergarten. We operationalize multiple dimensions of children's exposure to repeated change-including the frequency, concurrency, chronicity, timing, and types of changes children experience-in a nationally representative longitudinal cohort of U.S.-born children (Early Childhood Longitudinal Study-Birth Cohort, N ~ 4,750). We focus on early childhood, a period of substantial flux in children's family and neighborhood contexts. Predicted behavior scores differ by approximately one-fifth of a standard deviation for children who experienced high or chronic exposure to ecological change compared with those who experienced little or no change. These findings emphasize the distinctiveness of multidomain ecological instability as a risk factor for healthy development that should be conceptualized differently from the broader concept of normative levels of change in early childhood environments.
