A case study in developmental discontinuity: PROSPER Interventions and adolescent substance use trajectories shape young adult substance use and mental health problems.

The loss of John Schulenberg reverberates across the developmental and prevention sciences. In honor of his many contributions, this paper applies his ideas of developmental continuity and discontinuity to understand the process by which PROSPER delivered universal prevention programs (delivered in Grades 6 and 7) affect young adult outcomes. Guided by these developmental models, we deconstructed adolescent substance use initiation trajectories into two discrete phases-early and late adolescence, demarcated by substance use initiation levels at the end of 9th grade. We evaluated the effects of PROSPER interventions on these phases, and in turn, the effects of adolescent substance use initiation on young adult antisocial behavior, alcohol and drug use consequences, and depression symptoms. This sample included 1,984 young adults who participated in the PROSPER intervention trial in Grade 6 (two cohorts, 2002 and 2003), followed over 8 adolescent measurement occasions (Fall and Spring of Grade 6; Spring of Grades 7-12). Young adult outcomes were averaged across three waves (collected at ages 20, 23, and 25). PROSPER interventions were associated with reduced substance use initiation in early adolescence, but not escalation during late adolescence. In turn, substance use in both early and late adolescence was uniquely associated with young adult antisocial behavior, depression symptoms, and substance use consequences. PROSPER interventions were associated with young adult antisocial behavior and problematic substance use via reduced risk for early initiation status. Findings are discussed in terms of developmental continuity and discontinuity.

Parental warmth and young adult depression: A comparison of enduring effects and revisionist models.

Guided by a novel analytic framework, this study investigates the developmental mechanism through which parental warmth is related to young adult depression. Data were from a large sample of participants followed from early adolescence to young adulthood (N = 1,988; 54% female). Using structural equation modeling, we estimated and compared competing developmental models - enduring effects vs. revisionist models - to assess whether parental warmth during adolescence had enduring or transient effects on depression in young adulthood. We also examined whether contemporaneous experiences of parental warmth in young adulthood were more salient than parental warmth in adolescence. Results supported the revisionist model: early intergenerational experiences in adolescence predicted psychopathology early in young adulthood, but their unique effects gradually diminished; whereas parental warmth in young adulthood continued to be protective of young adult depression. Effects of mother and father warmth on young adult depression were similar in pattern and magnitude. Results were held when accounting for covariates such as adolescent sex, family income status, and family structure. Young adult mental health interventions may consider targeting maintenance or improvement in parental warmth to help offset the long-term impact of adversity early in life.

Family vulnerability and disruption during the COVID-19 pandemic: prospective pathways to child maladjustment.

BACKGROUND: This study evaluated two risk pathways that may account for increases in child internalizing and externalizing problems during the COVID-19 pandemic: one pathway operating through pre-existing family vulnerability and a second pathway operating through disruption in family functioning occurring in response to the pandemic. We assessed family disruption and family functioning with measures of key family-level and parenting dimensions, including family cohesion, conflict and routines, and parents' harsh discipline, lax discipline and warmth. In all models, pre-pandemic parent emotional distress, financial strain and child maladjustment were included as covariates. METHODS: The sample included 204 families, comprised of parents who had children (MAge = 4.17; 45.1% girls). Parents (MAge = 27.43) completed the first survey prior to COVID-19 onset in the United States, a second survey after COVID-19 onset in May 2020 and a third survey two weeks later. RESULTS: Analyses were conducted in a model-building fashion, first computing structural equation models for each family and parenting dimension separately, then advancing significant dimensions into one integrated model for the family-level factors and a second model for parenting quality factors. Results provided more support for the family disruption hypothesis across all tests. In the family-level domain, decreases in family cohesion and increases in family conflict each uniquely predicted subsequent child maladjustment. In the parenting domain, increases in harsh discipline and lax discipline each uniquely predicted subsequent child maladjustment. Family routines and parental warmth were not associated with child adjustment. However, parents' emotional distress prior to the pandemic exhibited a robust association with children's internalizing problems. CONCLUSIONS: These findings indicate that efforts to support families in adapting to unique conditions of the pandemic will yield the greatest effect for child adjustment. Specifically, interventions should include efforts to help families maintain cohesion and manage conflict, and help parents minimize increases in harsh and lax discipline.

Long-term Effects of Adolescent Substance Use Prevention on Participants, Partners, and their Children: Resiliency and Outcomes 15 Years Later During the COVID-19 Pandemic.

We examined whether participation in adolescent substance use prevention programming can enhance long-term resilience into adulthood such that individuals were better able to cope with adversities during the initial months of the COVID-19 pandemic, yielding benefits for the individuals, their partners/spouses, and children; 197 adults (28-30 years old) who entered the PROSPER randomized trial of substance use prevention programming as 6th graders and subsequently had become parents-and 128 of their partners-participated in two waves of long-term follow-up data collection. Respondents completed questionnaires on substance use, adjustment, parenting quality, and children's mood and behavior problems 15 years after baseline, and again via an online survey in the first three months of the COVID-19 pandemic. Results were mixed, with some indications of better adjustment of PROSPER intervention compared to control participants during the early phase of the pandemic (less increase in alcohol use and less decrease in parenting warmth) and their children (lower levels of externalizing and internalizing problems) but several null results as well (no differences in other substance use behaviors, other parenting measures, or parent depression). Adolescent substance use prevention programs can foster long-term individual and interpersonal resilience factors that allow participants-as well as their children-to adapt and cope with unforeseen periods of acute stress and adversity with less deterioration in health and well-being.

Collateral Benefits of Evidence-Based Substance Use Prevention Programming During Middle-School on Young Adult Romantic Relationship Functioning.

The quality of romantic relationships formed during early adulthood has critical implications for physical and psychological wellbeing, future romantic relationships, and subsequent parenting of the next generation. The present study evaluates the cross-over effects of the PROSPER-delivered adolescent substance use prevention programming on young adult romantic relationship functioning through a long-term developmental cascade of adolescent skills and behaviors, along with subsequent family-of-origin functioning. Prospective, longitudinal, bivariate growth models were used to analyze the effects of the PROSPER-delivered interventions in a sample of 1008 youths living in rural and semi-rural communities in Iowa and Pennsylvania, starting in sixth grade (AgeM = 11.8; 62% female) who were in a steady romantic relationship at the young adult assessment (AgeM = 19.5). Findings indicated a cascading effect through which PROSPER promotes adolescent problem-solving skills during early-to-mid-adolescence; problem-solving skills were associated with better family functioning during mid-adolescence; and family functioning was associated with better romantic relationship quality, indicated by lower levels of relationship violence and more effective relationship problem-solving in young adulthood. PROSPER, which primarily targets adolescent substance misuse and conduct problem prevention, has lasting, collateral effects that benefit young adults in their romantic relationship functioning - which may have further downstream benefits for their own relationships and those of their children (i.e., intergenerational transmission effects). These findings add to the growing body of literature evidencing important cross-over effects of widely disseminated substance use prevention programs delivered during adolescence.

COVID-19 family dynamics and health protective behavior adherence: A 16-wave longitudinal study.

OBJECTIVE: Health-protective behavior (HPB) adherence (wearing protective face masks, social distancing, and increased handwashing) plays a critical role in reducing infectious disease transmission; yet factors underlying HPB adherence are not well understood. Most research focuses on individual factors-beliefs about susceptibility, severity, and HPB efficacy; however, understanding parent and child HPB adherence may require a family conceptualization. This study evaluated whether family relations (cohesion, conflict, and chaos), as well as parent-child conflict regarding pandemic-specific circumstances (e.g., social distancing prohibitions about spending time with friends) account for parent and child HPB adherence, over and above parents' individual concerns about COVID-19 risks. METHOD: This study utilized data reported by parents in 204 families with children (Mage = 4.2; 45% girls) collected on 16 occasions between May 2020 through April 2021. The impact of within-person (WP) and between-person (BP) effects of each family-level factor on parent and child HPB adherence was evaluated in a series of two-level multilevel models. RESULTS: Over the course of the study, parent HPB adherence was generally stable and child HPB adherence declined early on but then leveled off. Results showed the protective effect of family cohesion for both parent and child HPB adherence at the WP and BP level. In addition, periods of higher COVID-19-related conflict corresponded to increases in parent and child HPB adherence. CONCLUSIONS: Intervention efforts should be directed at promoting family cohesion in order to promote sustained parent and child HPB adherence.

Multivariate growth trajectories of parenting practices in adolescence predicting young adult relationships with parents.

Guided by the life course perspective, this study investigated the developmental antecedents of contact, closeness/warmth, and negativity in young adults' relationships with their parents. Taking the developmental systems approach, we considered interindividual differences in not only initial levels of parenting quality in early adolescence (Grade 6) but also developmental changes in parenting quality across adolescence (Grades 6-12) as predictors of young adult-parent relationship quality. Data were from a large sample of young adults (N = 1,631; Mage = 22.84; 57% female; 90% White; 25% received free/reduced-price school lunch in Grade 6) followed from the fall of Grades 6 to 12 at eight time points, plus a young adult assessment. Using multivariate latent growth curve modeling, we identified a nuanced pattern of predictors of the three relationship dimensions. Higher initial levels of and lower rates of decline in parental involvement across adolescence predicted more young adult contact with mothers and fathers. Higher initial levels of parental warmth and parental involvement, as well as lower rates of decline in parental warmth, predicted greater closeness/warmth with mothers and fathers in young adulthood. Higher initial levels of and lower rates of decline in effective discipline predicted less young adult negativity toward mothers and fathers. These results held even when accounting for important adolescent and young adult covariates (adolescent sex and race, adolescent family income and structure, adolescent aggressive behavior tendencies, young adult living arrangement). The study offers new insights into how parenting practices in adolescence contribute to parent-child relationship in young adulthood. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Family vulnerability, disruption, and chaos predict parent and child COVID-19 health-protective behavior adherence.

INTRODUCTION: This study examined the role of family functioning in predicting family adherence to health-protective behaviors (HPBs) aimed at reducing COVID-19 spread. Pre-COVID-19 family functioning, disruptions to family functioning (cohesion, conflict, routines), and family chaos during the COVID-19 pandemic were tested as pathways to HPB adherence. METHOD: We utilized a sample of N = 204 families, comprising parents who had children (MAge = 4.17). Parents (MAge = 27.43) completed one survey prior to COVID-19 onset in the United States, and twice during COVID-19, at a 2-week interval. Structural equation modeling was used to test three potential pathways between prepandemic family-level functioning and HPB adherence during the COVID-19 pandemic. RESULTS: Findings indicated that families with higher levels of chaos during COVID-19 demonstrated consistently lower HPB adherence across all three models. Additionally, disruptions in family cohesion from pre-COVID was associated with lower levels of parent and child HPB adherence. Family conflict was indirectly associated with HPB adherence via family chaos during COVID-19; whereas family routines were not associated with HPB adherence at all. DISCUSSION: These findings suggest that family functioning is a meaningful predictor of HPB adherence. Family-based support may be effective in improving HPB adherence by focusing on promoting cohesion and reducing conflict and chaos for families coping with reduced community support and resources. Strategies for family-based supports are discussed. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Up, not down: The age curve in happiness from early adulthood to midlife in two longitudinal studies.

Happiness is an important indicator of well-being, and little is known about how it changes in the early adult years. We examined trajectories of happiness from early adulthood to midlife in 2 Canadian longitudinal samples: high school seniors followed from ages 18-43 and university seniors followed from ages 23-37. Happiness increased into the 30s in both samples, with a slight downturn by age 43 in the high school sample. The rise in happiness after high school and university remained after controlling for important baseline covariates (gender, parents' education, grades, self-esteem), time-varying covariates known to be associated with happiness (marital status, unemployment, self-rated physical health), and number of waves of participation. The upward trend in happiness runs counter to some previous cross-sectional research claiming a high point in happiness in the late teens, decreasing into midlife. As cross-sectional designs do not assess within-person change, longitudinal studies are necessary for drawing accurate conclusions about patterns of change in happiness across the life span.
