Comorbidity between body dissatisfaction and nicotine vaping among young adults in college: a daily diary study.

Objective: The purpose of this study was to elucidate comorbidity between body dissatisfaction and nicotine vaping. Participants: Participants were 121 college students (M age = 20.51 years; 75.0% female; 75.2% White) who participated in a 14-day daily diary study. Methods: Logistic regression was used to test links between baseline trait body dissatisfaction and vaping frequency across 14 days. Multilevel logistic regression was used to test within-person, daily links between body dissatisfaction and nicotine vaping. Results: Each additional unit of trait body dissatisfaction increased the odds of frequent vaping by 33% (95% CI [1.00, 1.77]) and daily vaping by 54% (95% CI [1.10, 2.15]). Within-person, daily associations between body dissatisfaction and vaping were nonsignificant. Conclusions: Body dissatisfaction may increase college students' risk for engaging in frequent nicotine vaping. However, daily changes in body dissatisfaction may not predict same- or next-day vaping. College students with body dissatisfaction may benefit from nicotine interventions.

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.

Examining profiles of convergence and divergence in reports of parental warmth: Links to adolescent developmental problems.

Parental warmth during the transition from childhood to adolescence is a key protective factor against a host of adolescent problems, including substance use, maladjustment, and diminished well-being. Moreover, adolescents and parents often disagree in their perceptions of parenting quality, and these discrepancies may confer risk for problem outcomes. The current study applies latent profile analysis to a sample of 687 mother-father-6th grade adolescent triads to identify patterns of adolescent-parent convergence and divergence in perceptions of parental warmth. Five profiles were identified, and associations with adolescent positive well-being, substance use, and maladjustment outcomes in 9th grade were assessed. Patterns of divergence in which adolescents had a pronounced negative perception of parental warmth compared to parents, as well as those wherein pronounced divergence was present in only one adolescent-parent dyad, were associated with diminished positive well-being compared to adolescents who had more positive perceptions of warmth than parents. Having more negative perceptions of warmth compared to parents was also associated with elevated risk for alcohol and marijuana initiation, but only when the divergence was pronounced rather than more moderate. These findings add nuance to findings from previous between-family investigations of informant discrepancies, calling for further family-centered methods for investigating multiple perspectives.

Daily dynamics of feeling loved by parents and their prospective implications for adolescent flourishing.

Feeling loved by one's caregiver is essential for individual flourishing (i.e., high levels of psychological well-being in multiple dimensions). Although similar constructs are found to benefit adolescent well-being, research that directly tests parental love as a feeling from the recipient's perspective is rare. Historically, parental love has been measured using single-assessment methods and assumed to be a stable, trait-like characteristic; yet, like any feeling, it may fluctuate in meaningful ways on a day-to-day basis-the implications of which are unknown. Using a sample of 150 adolescents (59.3% female; ages 14-16), this study estimated level (person's mean level across days) and instability (fluctuations across days) of feeling loved by a caregiver across 21 days for each adolescent, and then examined their prospective effects on adolescent flourishing 1 year later. After controlling for demographics (adolescent age, gender, family income, and parent's sex) and variable baseline levels, feeling more loved by one's caregiver in daily life significantly predicted higher levels of flourishing in two global measures 1 year later. Moreover, level and instability of feeling loved by one's caregiver played different roles for different dimensions of flourishing: higher levels significantly predicted higher levels of autonomy, purpose in life, and personal growth, whereas higher instability significantly predicted lower levels of positive relations with others and environmental mastery. Findings emphasized the importance of considering daily dynamics of feeling loved by one's caregiver and demonstrated that level (of feeling loved) is particularly important for intrapersonal aspects while instability is particularly important for interpersonal aspects of flourishing. RESEARCH HIGHLIGHTS: Adolescents feeling more loved by their caregiver in daily life had higher levels of overall flourishing 1 year later. Level (of feeling loved) is particularly important for intrapersonal aspects of adolescent flourishing, including autonomy, purpose in life, and personal growth. Stability (of feeling loved) is particularly important for interpersonal aspects of adolescent flourishing, including positive relations with others and environmental mastery.

A socioemotional network perspective on momentary experiences of family conflict in young adults.

Family conflict is an established predictor of psychopathology in youth. Traditional approaches focus on between-family differences in conflict. Daily fluctuations in conflict within families might also impact psychopathology, but more research is needed to understand how and why. Using 21 days of daily diary data and 6-times a day experience-sampling data (N = 77 participants; mean age = 21.18, SD = 1.75; 63 women, 14 men), we captured day-to-day and within-day fluctuations in family conflict, anger, anxiety, and sadness. Using multilevel models, we find that days of higher-than-usual anger are also days of higher-than-usual family conflict. Examining associations between family conflict and emotions within days, we find that moments of higher-than-usual anger predict higher-than-usual family conflict later in the day. We observe substantial between-family differences in these patterns with implications for psychopathology; youth showing the substantial interplay between family conflict and emotions across time had a more perseverative family conflict and greater trait anxiety. Overall, findings indicate the importance of increases in youth anger for experiences of family conflict during young adulthood and demonstrate how intensive repeated measures coupled with network analytic approaches can capture long-theorized notions of reciprocal processes in daily family life.

Dynamic characteristics of parent-adolescent closeness: Predicting adolescent emotion dysregulation.

Emotion dysregulation is linked to adolescent psychological problems. However, little is known about how lability in daily closeness of parent-adolescent dyads affects the development of emotion dysregulation. This study examined how closeness lability with parents was associated with emotion dysregulation 12 months later. The sample included 144 adolescents (M = 14.62, SD = 0.83) who participated in a baseline assessment, 21-day daily diaries, and a 12-month follow-up assessment. Parents and adolescents both reported adolescent emotion dysregulation at baseline and follow-up assessments, while adolescents reported daily parent-adolescent closeness. Results indicate that lability in father-adolescent closeness was associated with increased emotion dysregulation at 12 months reported by adolescents. However, lability in mother-adolescent closeness was not associated with adolescent emotion dysregulation. Moreover, when baseline father-adolescent closeness was high, greater lability in father-adolescent closeness was associated with decreased emotion dysregulation. Findings indicate that daily fluctuations in father-adolescent closeness are a key family characteristic that links to long-term adolescent emotion dysregulation.

The roles of caregivers and friends in adolescent daily emotion dynamics.

Daily emotion dynamics provide valuable information about individuals' emotion processes as they go about their lives. Emotion dynamics such as emotion levels (mean), emotion variability (degree of fluctuation), and emotion network density (strength of temporal connections among emotions) are associated with risks for various psychopathology in youth and adults. Prior work has shown that caregivers and friends play crucial socializing roles in adolescent emotional well-being, but less is known about their roles in daily emotion dynamics. This study examined whether caregiver emotion coaching, caregiver-adolescent closeness, and friendship quality were associated with adolescents' emotion levels, emotion variability, and emotion network density. Further, we examined whether caregiver-adolescent closeness moderated the associations between coaching and emotion dynamics. Participants were 150 adolescents (61% girls; Mage = 14.75) and one of their caregivers (95% female; Mage = 43.35) who completed a baseline survey and 21 daily surveys. Results showed that caregiver emotion coaching interacted with caregiver-adolescent closeness in predicting emotion levels and variability. Specifically, when closeness was higher, emotion coaching was significantly associated with lower sadness and anger levels, higher happiness levels, and lower happiness variability. Caregiver emotion coaching, independent of closeness, was also associated with lower anxiety levels, lower sadness variability, and lower emotion network density. Friendship quality was significantly associated with lower levels of sadness, anxiety, and anger, higher levels of happiness, and lower variability in anxiety and anger. These findings suggest that caregivers and friends are central to everyday emotion levels and variability and a more flexible emotion system in adolescents.

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.

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.

Adolescents' and parents' affect in relation to discrepant perceptions of parental warmth in daily life.

The current study aimed to evaluate how adolescents' and parents' perceptions of daily parenting-and their discrepancies-relate to daily parent and adolescent affect. Daily parental warmth and affect were assessed using electronic diaries in 150 American adolescent-parent dyads (61.3% females, Mage = 14.6, 83.3% White; 95.3% mothers, Mage = 43.4; 89.3% White) and in 80 Dutch adolescents with 79 mothers and 72 fathers (63.8% females, Mage = 15.9, 91.3% White; Mage = 49.0, 97.4% White). Results of preregistered models indicated that individuals' affect may be more important for perceptions of parenting than discrepancies between parent-adolescent reports of parenting for affect, stressing the need to be aware of this influence of affect on parenting reports in clinical and research settings.

Interparental conflict, family climate, and threat appraisals: Early adolescent exposure and young adult psychopathology risk.

Long-term studies evaluating threat appraisals as an intervening variable linking interparental conflict (IPC) and internalizing problems are lacking, as are longitudinal studies evaluating the role of the broader family context in these models. Guided by the cognitive-contextual framework, this study followed 225 adolescents (53% females) and their families from age 11 into young adulthood (age 19.6) to evaluate the long-term implications of IPC and threat appraisals for young adult internalizing symptoms. First, a long-term mediation model revealed that increases in IPC from age 11 to 14 (but not initial levels) best accounted for adolescent threat appraisals at age 14. In turn, threat appraisals mediated the association between IPC and young adult (age 19.6) internalizing problems. Second, the family climate-defined as high levels of cohesion and organization-moderated the relation between IPC and threat appraisals. Adolescents in families that experienced declines in positive family climate and increasing IPC had the highest threat appraisals; however, families that maintained (or increased in) positive family climate were protective against increasing IPC. Interestingly, the combination of decreasing IPC and decreasing positive family climate corresponded with the lowest threat appraisals in the sample, contrary to expectations. This finding seems consistent with a family disengagement perspective which may be less threatening to adolescents but may confer risk for other problem outcomes. This study underscores the importance of IPC and threat appraisals during adolescence, and offers new insights into the role of the family climate in protecting against escalating IPC for young adult internalizing risk.

Age-Varying Associations Between Attempts to Lose Weight and Nicotine Vaping Across Adolescence: Results From a Nationally Representative Sample.

PURPOSE: The prevalence of nicotine vaping is increasing among adolescents and emerging evidence suggests weight concerns may promote risk for vaping. The aims of this study were to investigate whether there is an association between attempting to lose weight and nicotine vaping during adolescence, when this association emerges and is strongest, and whether there are sex differences in this link. METHODS: This study used time-varying effect modeling, an analytic method that estimates regression coefficients as a continuous function of age, to model dynamic associations between weight loss behavior and nicotine vaping across adolescence and sex differences in these links. Data were from 13,677 adolescents (aged 14-18 years, 49.4% female) who participated in the 2019 National Youth Risk Behavior Survey, a nationally representative U.S. RESULTS: Results revealed an age-varying association that differed by sex. Girls who were trying to lose weight were at a higher risk for past 30-day vaping from ages 14.2-15.9 years, with the strongest association at 14.8 years (odds ratio [OR] = 1.92, 95% confidence interval [CI] [1.25, 2.95]). For boys, this association was nonsignificant across age (OR = 1.76, 95% CI [0.91, 3.41] at age 14.0 years). Girls who were trying to lose weight were at a higher risk for frequent vaping (vaping on 20-30 of the past 30 days) from ages 15.2-17.1 years, with the strongest association at 16.1 years (OR = 2.59, 95% CI [1.45, 4.62]). This link was not meaningfully significant at any age for boys (OR = 3.26, 95% CI [0.86, 12.33] at age 14.0 years). DISCUSSION: Girls, but not boys, who are trying to lose weight appear vulnerable to nicotine vaping during adolescence.

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).

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.

Profiles of future expectations among urban adolescents in Cambodia.

Adolescents are tasked with navigating competing priorities, including whether to marry, have children, pursue a job/career, go to college, and contribute to society. The developmental task of building expectations for the future is especially complex for Cambodian adolescents living within a society that strongly prioritizes family obligations yet increasingly provides educational and professional opportunities. The current study, guided by Seginer's (2003) future orientation model, applied latent profile analysis (LPA) to explore patterns of Cambodian adolescents' (N = 580, 64% female, Mage = 15.85) future expectations across key life domains and predictors of those patterns. LPA identified four profiles: Low Expectancy (low expectations across all domains; 12%), Family Focused (high expectations to get married and have children; 31%), Professional/Service Focused (high expectations across education, employment, and societal contribution domains; 27%), and High Expectancy (high expectations across all domains; 30%). Females were more likely than males to be in the Professional/Service Focused than High Expectancy profile. Adolescents with greater internal locus of control and family obligation were less likely to be in the Low Expectancy and Family Focused than High Expectancy profile, whereas adolescents in higher grade levels were more likely to be in the Family Focused than High Expectancy profile. Adolescents with closer relationships with mothers were less likely to be in the Professional/Service Focused than High Expectancy profile; adolescents with closer relationships with fathers were more likely to be in the Professional/Service Focused than High and Low Expectancy profiles. Findings elucidate configurations of adolescents' future expectations, and factors distinguishing among adolescents with different configurations.

Reexamining the association between the interparental relationship and parent-child interactions: Incorporating heritable influences.

Family systems research has identified two key processes (spillover and compensatory), linking interparental relationship quality to the parent-child relationship. However, previous research has focused on the parent as the sole initiator and had not often considered the role of the child in these processes. The present study adds to the literature by leveraging a genetically informed design to examine possible child evocative effects on spillover and compensatory processes. Participants were from a longitudinal parent-offspring adoption sample of 361 linked sets of adoptive parents of an adopted child (57% male), and the child's birth parents. Adoptive parents reported on child pleasure and anger at 18 months and the interparental relationship at 27 months. Parent-child interactions were observed at child age 6 years, and heritable influences were assessed via birth mother self-report at 5 months. Our results indicated a dampening effect where higher interparental warmth at child age 27 months was associated with less adoptive mother-child coercion at child age 6 years, and a compensatory effect where higher interparental conflict was associated with more adoptive father-child positive engagement. Moreover, our results indicated child-driven effects via both genetic and environmental pathways. Specifically, higher levels of birth mother negative affect (heritable characteristic) were associated with lower levels of adoptive father-child coercion. Also, child anger was positively associated with interparental conflict, and child pleasure was positively associated with interparental warmth. These findings support findings from the family literature with evidence of compensatory mechanisms, while also highlighting the active role children play in shaping family interactions.

When do adolescents feel loved? A daily within-person study of parent-adolescent relations.

Feeling loved has many benefits, but research is limited on how daily behaviors of one person in a relationship shape why someone else feels more or less loved from day to day. The parent-adolescent relationship is a primary source of love. We expected parent-reported warmth and conflict would explain daily fluctuations in how loved adolescents reported feeling. In a sample of 151 families (adolescent MAge = 14.60; 61.6% female) over a 21-day period, we used multilevel models to disentangle within-family (daily variability) and between-family (average levels) parent-reported daily warmth and conflict in relation to adolescents' daily reports about how loved they were feeling. Findings indicated adolescents in families with higher parent-reported warmth across days and higher adolescent-reported closeness with parents felt more loved by their parents, on average. At a within-person level, we found considerable day-to-day variability in how loved adolescents reported feeling that was partially explained by meaningful variability in both parent-reported warmth and conflict across days. On days when parents reported more warmth than usual and less conflict than usual, adolescents reported feeling more loved. Further, a significant within-day interaction indicated that the importance of days' parent warmth was greater on high conflict days, but when parents directed more warmth toward their adolescents, the difference between high- and low-conflict days was negligible. Theoretical implications for studying daily emotional love in parent-youth relationships and suggestions for parenting interventions that focus on daily practices of parent warmth are discussed.

Family and individual risk factors for triangulation: Evaluating evidence for emotion coaching buffering effects.

Adolescents who are triangulated into interparental conflict are at increased risk for psychological maladjustment. However, little is known about factors that may predict family risk for triangulating adolescents, or protective factors that can off-set this risk. In this study, we conducted longitudinal tests of family, parent, and adolescent factors that might predict increases in triangulation over time. The sample included 174 adolescents and their mother figures from two-parent families (58% female; Mage  = 14.75 years) who provided data on two occasions, six months apart. Hierarchical linear regression models evaluated family, parent, and adolescent risk factors for triangulation into interparental conflict, and subsequently parent's emotion coaching and adolescent gender as potential moderators of risk for triangulation. Findings revealed that low family cohesion, parent depression, and adolescent difficulties with emotion regulation represented risks for triangulation. Parent emotion coaching moderated the association between low interparental love and triangulation differentially based on adolescent gender.

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).

Triadic family structures and their day-to-day dynamics from an adolescent perspective: A multilevel latent profile analysis.

Relationship structure (patterns of relative closeness among multiple family members) and dynamics (changes in relationship structures overtime) are two main aspects of family system functioning, yet empirical tests of these concepts lag behind theory. Recent growth in advanced methods for complex data structures makes it possible to empirically capture structures and dynamics within multiple family relationships overtime. To answer how relationship structure may fluctuate from day to day, this study used multilevel latent profile analysis (MLPA) as an innovative and feasible method to capture mother-father-adolescent (MFA) relationship structures and dynamics on a daily basis. Using daily adolescent reports of mother-father (MF), mother-adolescent (MA), and father-adolescent (FA) closeness from 144 two-parent families for up to 21 days, we identified six day-level MFA structures: Cohesive (33% of days; three close dyads), Mother-Centered (9%; closer MF, average MA, less close FA), Adolescent-Centered (4%; less close MF, closer MA and FA), MA-Coalition (3%; closer MA, less close MF and FA), Disengaged (23%; three less close dyads), and Average (28%; three approximately average dyads). We identified five types of MFA dynamics at the family level: Stable Cohesive (35% of families; exhibited Cohesive structure most days), Stable Disengaged (20%; Disengaged structure most days), Stable MA-Coalition (3%; MA-Coalition structure most days), Stable Average (24%; Average structure most days), and Variable (17%; varied among multiple structures). Methodologically, daily diary designs and MLPA can be useful tools to empirically examine concrete hypotheses of complex, non-linear processes in family systems. Substantive and methodological implications are discussed.

La estructura de las relaciones (los patrones de cercanía relativa entre varios miembros de la familia) y su dinámica (los cambios en las estructuras de las relaciones con el tiempo) son dos aspectos principales del funcionamiento familia-sistema, sin embargo, las pruebas empíricas de estos conceptos se retrasan en relación con la teoría. El crecimiento reciente en los métodos avanzados de estructuras de datos complejos hace posible captar empíricamente las estructuras y la dinámica dentro de las relaciones de varias familias con el tiempo. Para responder cómo la estructura de las relaciones puede variar día a día, se utilizó en este estudio un análisis de perfiles latentes multinivel como método innovador y viable para captar las estructuras y la dinámica de las relaciones madre-padre-adolescente (MPA) diariamente. Utilizando informes diarios de los adolescentes sobre la cercanía madre-padre (MP), madre-adolescente (MA) y padre-adolescente (PA) de 144 familias de dos padres durante un máximo de 21 días, identificamos seis estructuras MPA de nivel diario: cohesiva (el 33 % de los días; tres díadas cercanas), centrada en la madre (el 9 %; más cercanía MP, MA promedio, menos cercanía PA), centrada en el adolescente (el 4 %; menos cercanía MP, más cercanía MA y PA), alianza MA (el 3 %; mas cercanía MA, menos cercanía MP y PA), indiferente (el 23 %; tres díadas menos cercanas), y promedio (el 28 %; tres díadas aproximadamente promedio). Identificamos tres tipos de dinámica MPA al nivel de la familia: cohesiva estable (el 35 % de las familias demostró una estructura cohesiva la mayoría de los días), indiferente estable (el 20 %; estructura indiferente la mayoría de los días), alianza MA estable (el 3 %; estructura de alianza MA la mayoría de los días), promedio estable (el 24 %; estructura promedio la mayoría de los días), y variable (el 17 %; varió entre numerosas estructuras). Metodológicamente, los diseños de registro diario y el análisis de perfiles latentes multinivel pueden ser herramientas útiles para analizar empíricamente hipótesis concretas de los procesos complejos y no lineales de los sistemas familiares. Se debaten las consecuencias sustanciales y metodológicas.
