How adolescents' lives were disrupted over the course of the COVID-19 pandemic: A longitudinal investigation in 12 cultural groups in 9 nations from March 2020 to July 2022.

It is unclear how much adolescents' lives were disrupted throughout the COVID-19 pandemic or what risk factors predicted such disruption. To answer these questions, 1,080 adolescents in 9 nations were surveyed 5 times from March 2020 to July 2022. Rates of adolescent COVID-19 life disruption were stable and high. Adolescents who, compared to their peers, lived in nations with higher national COVID-19 death rates, lived in nations with less stringent COVID-19 mitigation strategies, had less confidence in their government's response to COVID-19, complied at higher rates with COVID-19 control measures, experienced the death of someone they knew due to COVID-19, or experienced more internalizing, externalizing, and smoking problems reported more life disruption due to COVID-19 during part or all of the pandemic. Additionally, when, compared to their typical levels of functioning, adolescents experienced spikes in national death rates, experienced less stringent COVID-19 mitigation measures, experienced less confidence in government response to the COVID-19 pandemic, complied at higher rates with COVID-19 control measures, experienced more internalizing problems, or smoked more at various periods during the pandemic, they also experienced more COVID-19 life disruption. Collectively, these findings provide new insights that policymakers can use to prevent the disruption of adolescents' lives in future pandemics.

Adolescents' relationships with parents and romantic partners in eight countries.

INTRODUCTION: Creating romantic relationships characterized by high-quality, satisfaction, few conflicts, and reasoning strategies to handle conflicts is an important developmental task for adolescents connected to the relational models they receive from their parents. This study examines how parent-adolescent conflicts, attachment, positive parenting, and communication are related to adolescents' romantic relationship quality, satisfaction, conflicts, and management. METHOD: We interviewed 311 adolescents at two time points (females = 52%, ages 15 and 17) in eight countries (China, Colombia, Italy, Kenya, the Philippines, Sweden, Thailand, and the United States). Generalized and linear mixed models were run considering the participants' nesting within countries. RESULTS: Adolescents with negative conflicts with their parents reported low romantic relationship quality and satisfaction and high conflicts with their romantic partners. Adolescents experiencing an anxious attachment to their parents reported low romantic relationship quality, while adolescents with positive parenting showed high romantic relationship satisfaction. However, no association between parent-adolescent relationships and conflict management skills involving reasoning with the partner was found. No associations of parent-adolescent communication with romantic relationship dimensions emerged, nor was there any effect of the country on romantic relationship quality or satisfaction. CONCLUSION: These results stress the relevance of parent-adolescent conflicts and attachment as factors connected to how adolescents experience romantic relationships.

Comparing apples to manzanas and oranges to naranjas: A new measure of English-Spanish vocabulary for dual language learners.

The valid assessment of vocabulary development in dual-language-learning infants is critical to developmental science. We developed the Dual Language Learners English-Spanish (DLL-ES) Inventories to measure vocabularies of U.S. English-Spanish DLLs. The inventories provide translation equivalents for all Spanish and English items on Communicative Development Inventory (CDI) short forms; extended inventories based on CDI long forms; and Spanish language-variety options. Item-Response Theory analyses applied to Wordbank and Web-CDI data (n = 2603, 12-18 months; n = 6722, 16-36 months; half female; 1% Asian, 3% Black, 2% Hispanic, 30% White, 64% unknown) showed near-perfect associations between DLL-ES and CDI long-form scores. Interviews with 10 Hispanic mothers of 18- to 24-month-olds (2 White, 1 Black, 7 multi-racial; 6 female) provide a proof of concept for the value of the DLL-ES for assessing the vocabularies of DLLs.

Developmental Trajectories of Parental Self-Efficacy as Children Transition to Adolescence in Nine Countries: Latent Growth Curve Analyses.

Little is known about the developmental trajectories of parental self-efficacy as children transition into adolescence. This study examined parental self-efficacy among mothers and fathers over 3 1/2 years representing this transition, and whether the level and developmental trajectory of parental self-efficacy varied by cultural group. Data were drawn from three waves of the Parenting Across Cultures (PAC) project, a large-scale longitudinal, cross-cultural study, and included 1178 mothers and 1041 fathers of children who averaged 9.72 years of age at T1 (51.2% girls). Parents were from nine countries (12 ethnic/cultural groups), which were categorized into those with a predominant collectivistic (i.e., China, Kenya, Philippines, Thailand, Colombia, and Jordan) or individualistic (i.e., Italy, Sweden, and USA) cultural orientation based on Hofstede's Individualism Index (Hofstede Insights, 2021). Latent growth curve analyses supported the hypothesis that parental self-efficacy would decline as children transition into adolescence only for parents from more individualistic countries; parental self-efficacy increased over the same years among parents from more collectivistic countries. Secondary exploratory analyses showed that some demographic characteristics predicted the level and trajectory of parental self-efficacy differently for parents in more individualistic and more collectivistic countries. Results suggest that declines in parental self-efficacy documented in previous research are culturally influenced.

Infants of mothers with early remitted clinical depression and mothers with no postpartum depression: Adaptive functioning in the second year of life.

Whether and how remitted clinical depression in postpartum motherhood contributes to poor infant adaptive functioning is inconclusive. The present longitudinal study examines adaptive functioning in infants of mothers diagnosed as clinically depressed at 5 months but remitted at 15 and 24 months. Fifty-five U. S. mothers with early, remitted clinical depression and 132 mothers without postpartum depression completed the Vineland Adaptive Behavior Scales about their infants at 15 and 24 months. Between groups, mothers were equivalent in age, ethnicity, marital status, and receptive vocabulary (a proxy for verbal intelligence), and infants were equivalent in age and distribution of gender. Controlling for maternal education and parity, mothers with early, remitted clinical depression and mothers with no postpartum depression rated their infants similarly on communication, daily living skills, and socialization. Mothers with early, remitted clinical depression rated their infants poorer in motor skills. Girls were rated more advanced than boys in communication at 24 months and daily living skills at 15 and 24 months. Rated infant adaptive behavior skills increased from 15 to 24 months. With exceptions, adaptive functioning in infants may be robust to early, remitted maternal depression, and adaptive functioning presents a domain to promote positive development in this otherwise vulnerable population.

Cultural values, parenting, and child adjustment in the United States.

We examined whether cultural values, conformity and parenting behaviours were related to child adjustment in middle childhood in the United States. White, Black and Latino mothers (n = 273), fathers (n = 182) and their children (n = 272) reported on parental individualism and collectivism, conformity values, parental warmth, monitoring, family obligation expectations, and child internalising and externalising behaviours. Mean differences, bivariate correlations and multiple regression analyses were performed on variables of interest. Collectivism in mothers and fathers was associated with family obligation expectations and parental warmth. Fathers with higher conformity values had higher expectations of children's family obligations. Child internalising and externalising behaviours were greater when Latino families subscribed to individualistic values. These results are discussed in the context of cultural values, protective and promotive factors of behaviour, and race/ethnicity in the United States.

Individualism, collectivism and conformity in nine countries: Relations with parenting and child adjustment.

This study investigated how individualism, collectivism and conformity are associated with parenting and child adjustment in 1297 families with 10-year-old children from 13 cultural groups in nine countries. With multilevel models disaggregating between- and within-culture effects, we examined between- and within-culture associations between maternal and paternal cultural values, parenting dimensions and children's adjustment. Mothers from cultures endorsing higher collectivism and fathers from cultures endorsing lower individualism engage more frequently in warm parenting behaviours. Mothers and fathers with higher-than-average collectivism in their culture reported higher parent warmth and expectations for children's family obligations. Mothers with higher-than-average collectivism in their cultures more frequently reported warm parenting and fewer externalising problems in children, whereas mothers with higher-than-average individualism in their culture reported more child adjustment problems. Mothers with higher-than-average conformity values in their culture reported more father-displays of warmth and greater mother-reported expectations for children's family obligations. Fathers with higher-than-average individualism in their culture reported setting more rules and soliciting more knowledge about their children's whereabouts. Fathers who endorsed higher-than-average conformity in their culture displayed more warmth and expectations for children's family obligations and granted them more autonomy. Being connected to an interdependent, cohesive group appears to relate to parenting and children's adjustment.

Parenting knowledge and parenting self-efficacy of mothers with borderline personality disorder and depression: "I know what to do but think I am not doing it".

Borderline personality disorder (BPD) is a complex mental health condition often associated with previous childhood adversity including maladaptive parenting. When becoming a parent themselves, mothers with BPD have difficulties with various parenting cognitions and practices, but unknown is whether they have appropriate knowledge of sensitive parenting. This study explored whether differences in parenting knowledge or self-efficacy are specific to BPD or also found in mothers with depression, and whether symptom severity or specific diagnosis better explain parenting perceptions. Mothers with BPD (n = 26), depression (n = 25) or HCs (n = 25) completed a Q-sort parenting knowledge task and a parenting self-efficacy questionnaire. Results showed mothers with BPD had the same knowledge of sensitive parenting behaviors as mothers with depression and healthy mothers. Self-reported parenting self-efficacy was lower in mothers with BPD and depression compared with healthy mothers, with symptom severity most strongly associated. A significant but low correlation was found between parenting self-efficacy and knowledge. Findings suggest that mothers with BPD and depression know what good parenting is but think they are not parenting well. Mental health difficulties are not associated with parenting knowledge, but symptom severity appears to be a common pathway to lower parenting self-efficacy. Future interventions should test whether reduction of symptom severity or positive parenting feedback could improve parenting self-efficacy.

Pre-pandemic psychological and behavioral predictors of responses to the COVID-19 pandemic in nine countries.

Prior to the COVID-19 pandemic, adolescents (N = 1,330; Mages = 15 and 16; 50% female), mothers, and fathers from nine countries (China, Colombia, Italy, Jordan, Kenya, Philippines, Sweden, Thailand, United States) reported on adolescents' internalizing and externalizing problems, adolescents completed a lab-based task to assess tendency for risk-taking, and adolescents reported on their well-being. During the pandemic, participants (Mage = 20) reported on changes in their internalizing, externalizing, and substance use compared to before the pandemic. Across countries, adolescents' internalizing problems pre-pandemic predicted increased internalizing during the pandemic, and poorer well-being pre-pandemic predicted increased externalizing and substance use during the pandemic. Other relations varied across countries, and some were moderated by confidence in the government's handling of the pandemic, gender, and parents' education.

Predicting child aggression: The role of parent and child endorsement of reactive aggression across 13 cultural groups in 9 nations.

Parent and child endorsement of reactive aggression both predict the emergence of child aggression, but they are rarely studied together and in longitudinal contexts. The present study does so by examining the unique predictive effects of parent and child endorsement of reactive aggression at age 8 on child aggression at age 9 in 1456 children from 13 cultural groups in 9 nations. Multiple group structural equation models explored whether age 8 child and parent endorsement of reactive aggression predicted subsequent age 9 child endorsement of reactive aggression and child aggression, after accounting for prior child aggression and parent education. Results revealed that greater parent endorsement of reactive aggression at age 8 predicted greater child endorsement of aggression at age 9, that greater parent endorsement of reactive aggression at age 8 uniquely predicted greater aggression at age 9 in girls, and that greater child endorsement of reactive aggression at age 8 uniquely predicted greater aggression at age 9 in boys. All three of these associations emerged across cultures. Implications of, and explanations for, study findings are discussed.

Probing the association between maternal anxious attachment style and mother-child brain-to-brain coupling during passive co-viewing of visual stimuli.

Brain-to-brain coupling during co-viewing of video stimuli reflects similar intersubjective mentalisation processes. During an everyday joint activity of watching video stimuli (television shows) with her child, an anxiously attached mother's preoccupation with her child is likely to distract her from understanding the mental state of characters in the show. To test the hypothesis that reduced coupling in the medial prefrontal cortex (PFC) would be observed with increasing maternal attachment anxiety (MAA), we profiled mothers' MAA using the Attachment Style Questionnaire and used functional Near-infrared Spectroscopy (fNIRS) to assess PFC coupling in 31 mother-child dyads while they watched three 1-min animation videos together. Reduced coupling was observed with increasing MAA in the medial right PFC cluster which is implicated in mentalisation processes. This result did not survive control analyses and should be taken as preliminary. Reduced coupling between anxiously-attached mothers and their children during co-viewing could undermine quality of shared experiences.

The Intergenerational Transmission of Maladaptive Parenting and its Impact on Child Mental Health: Examining Cross-Cultural Mediating Pathways and Moderating Protective Factors.

Using a sample of 1338 families from 12 cultural groups in 9 nations, we examined whether retrospectively remembered Generation 1 (G1) parent rejecting behaviors were passed to Generation 2 (G2 parents), whether such intergenerational transmission led to higher Generation 3 (G3 child) externalizing and internalizing behavior at age 13, and whether such intergenerational transmission could be interrupted by parent participation in parenting programs or family income increases of > 5%. Utilizing structural equation modeling, we found that the intergenerational transmission of parent rejection that is linked with higher child externalizing and internalizing problems occurs across cultural contexts. However, the magnitude of transmission is greater in cultures with higher normative levels of parent rejection. Parenting program participation broke this intergenerational cycle in fathers from cultures high in normative parent rejection. Income increases appear to break this intergenerational cycle in mothers from most cultures, regardless of normative levels of parent rejection. These results tentatively suggest that bolstering protective factors such as parenting program participation, income supplementation, and (in cultures high in normative parent rejection) legislative changes and other population-wide positive parenting information campaigns aimed at changing cultural parenting norms may be effective in breaking intergenerational cycles of maladaptive parenting and improving child mental health across multiple generations.

Parenting, Adolescent Sensation Seeking, and Subsequent Substance Use: Moderation by Adolescent Temperament.

Although previous research has identified links between parenting and adolescent substance use, little is known about the role of adolescent individual processes, such as sensation seeking, and temperamental tendencies for such links. To test tenets from biopsychosocial models of adolescent risk behavior and differential susceptibility theory, this study investigated longitudinal associations among positive and harsh parenting, adolescent sensation seeking, and substance use and tested whether the indirect associations were moderated by adolescent temperament, including activation control, frustration, sadness, and positive emotions. Longitudinal data reported by adolescents (n = 892; 49.66% girls) and their mothers from eight cultural groups when adolescents were ages 12, 13, and 14 were used. A moderated mediation model showed that parenting was related to adolescent substance use, both directly and indirectly, through sensation seeking. Indirect associations were moderated by adolescent temperament. This study advances understanding of the developmental paths between the contextual and individual factors critical for adolescent substance use across a wide range of cultural contexts.

Predicting Adolescent Mental Health Outcomes Across Cultures: A Machine Learning Approach.

Adolescent mental health problems are rising rapidly around the world. To combat this rise, clinicians and policymakers need to know which risk factors matter most in predicting poor adolescent mental health. Theory-driven research has identified numerous risk factors that predict adolescent mental health problems but has difficulty distilling and replicating these findings. Data-driven machine learning methods can distill risk factors and replicate findings but have difficulty interpreting findings because these methods are atheoretical. This study demonstrates how data- and theory-driven methods can be integrated to identify the most important preadolescent risk factors in predicting adolescent mental health. Machine learning models examined which of 79 variables assessed at age 10 were the most important predictors of adolescent mental health at ages 13 and 17. These models were examined in a sample of 1176 families with adolescents from nine nations. Machine learning models accurately classified 78% of adolescents who were above-median in age 13 internalizing behavior, 77.3% who were above-median in age 13 externalizing behavior, 73.2% who were above-median in age 17 externalizing behavior, and 60.6% who were above-median in age 17 internalizing behavior. Age 10 measures of youth externalizing and internalizing behavior were the most important predictors of age 13 and 17 externalizing/internalizing behavior, followed by family context variables, parenting behaviors, individual child characteristics, and finally neighborhood and cultural variables. The combination of theoretical and machine-learning models strengthens both approaches and accurately predicts which adolescents demonstrate above average mental health difficulties in approximately 7 of 10 adolescents 3-7 years after the data used in machine learning models were collected.

Compliance with Health Recommendations and Vaccine Hesitancy During the COVID Pandemic in Nine Countries.

Longitudinal data from the Parenting Across Cultures study of children, mothers, and fathers in 12 cultural groups in nine countries (China, Colombia, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the USA; N = 1331 families) were used to understand predictors of compliance with COVID-19 mitigation strategies and vaccine hesitancy. Confidence in government responses to the COVID pandemic was also examined as a potential moderator of links between pre-COVID risk factors and compliance with COVID mitigation strategies and vaccine hesitancy. Greater confidence in government responses to the COVID pandemic was associated with greater compliance with COVID mitigation strategies and less vaccine hesitancy across cultures and reporters. Pre-COVID financial strain and family stress were less consistent predictors of compliance with COVID mitigation strategies and vaccine hesitancy than confidence in government responses to the pandemic. Findings suggest the importance of bolstering confidence in government responses to future human ecosystem disruptions, perhaps through consistent, clear, non-partisan messaging and transparency in acknowledging limitations and admitting mistakes to inspire compliance with government and public health recommendations.

Positive parenting, adolescent adjustment, and quality of adolescent diet in nine countries.

INTRODUCTION: We sought to understand the relation between positive parenting and adolescent diet, whether adolescents' internalizing and externalizing behaviors mediate relations between positive parenting and adolescent diet, and whether the same associations hold for both boys and girls and across cultural groups. METHODS: Adolescents (N = 1334) in 12 cultural groups in nine countries were followed longitudinally from age 12 to 15. We estimated two sets of multiple group structural equation models, one by gender and one by cultural group. RESULTS: Modeling by gender, our findings suggest a direct effect of positive parenting at age 12 on a higher quality diet at age 15 for males (ß = .140; 95% CI: 0.057, 0.229), but an indirect effect of positive parenting at age 12 on a higher quality diet at age 15 by decreasing externalizing behaviors at age 14 for females (ß = .011; 95% CI: 0.002, 0.029). Modeling by cultural group, we found no significant direct effect of positive parenting at age 12 on the quality of adolescent diet at age 15. There was a significant negative effect of positive parenting at age 12 on internalizing (ß = -.065; 95% CI: -0.119, -0.009) and externalizing at age 14 (ß = -.033; 95% CI: -0.086, -0.018). CONCLUSIONS: We founder gender differences in the relations among positive parenting, adolescents' externalizing and internalizing behaviors, and adolescent diet. Our findings indicate that quality of parenting is important not only in promoting adolescent mental health but potentially also in promoting the quality of adolescents' diet.

Multimodal assessments of preterm temperament across the first year of life: Continuity, stability, and moderation by country of origin and infant age.

There is limited research regarding the continuity, stability, and role of country of origin in preterm infant temperament across the first year of life. This prospective longitudinal study examined patterns of mean-level continuity and individual-differences stability of select scales of temperament at 6 and 12 months in preterm infants from three countries, Chile (n = 47), United Kingdom (n = 44), and United States (n = 50). Temperament was assessed with the Infant Behavior Questionnaire and observed using the Bayley Behavior Rating Scale. Continuity and stability across infant age, country effects, and interactions of country and age on preterm infant temperament were examined. Chilean mothers rated infants higher in soothability, duration of orienting, and orientation/engagement compared with mothers from the United Kingdom and/or United States. Continuity of temperament from 6 to 12 months varied by country: Chilean mothers reported increasing smiling and laughter and activity level from 6 to 12 months, and mothers from the United Kingdom reported decreasing smiling and laughter and increasing fear from 6 to 12 months. Infant temperament was stable in all three countries. Correlations evidenced low concordance between maternal reports and examiner observations of infant temperament at 12 months. However, among Chilean infants, higher maternal reported activity level was associated with higher examiner observed orientation/engagement score.

Hay una limitada investigación acerca de la continuidad, la estabilidad y el papel del país de origen en el temperamento de infantes nacidos prematuramente a lo largo del primer año de vida. Este potencial estudio longitudinal examinó patrones de continuidad en el promedio de nivel y las diferencias individuales en cuanto a la estabilidad de selectas escalas de temperamento a los 6 y 12 meses en infantes prematuros de tres países, Chile (n = 47), Reino Unido (n = 44) y Estados Unidos (n = 50). El temperamento se evaluó con el Cuestionario de Comportamiento del Infante y el mismo se observó usando la Escala de Puntuación del Comportamiento de Bayley. Se examinaron la continuidad y la estabilidad a lo largo de la edad del infante, los efectos del país, así como las interacciones entre país y edad en el temperamento de los infantes prematuros. Las madres chilenas evaluaron a sus infantes con más altos puntajes en cuanto a posibilidad de tranquilizarlos, duración de orientarlos y la orientación/participación en comparación con madres del Reino Unidos y/o de Estados Unidos. La continuidad de temperamento de los 6 a 12 meses varió según el país: las madres chilenas reportaron aumento en la sonrisa y la risa, y el nivel de actividad de los 6 a 12 meses, y las madres del Reino Unido reportaron una disminución en la sonrisa y la risa, y un aumento en el temor de los 6 a 12 meses. El temperamento del infante fue estable en los tres países. Las correlaciones son evidencia de la concordancia entre los reportes maternos y las observaciones del examinador del temperamento del infante a los 12 meses. Sin embrago, entre los infantes chilenos, el más alto nivel de actividad reportado por las madres se asoció con un más alto puntaje del examinador en cuanto a la observada orientación/participación.

Nous n'avons que des recherches limitées sur la continuité, la stabilité et le rôle du pays d'origine dans le tempérament du bébé prématuré au fil de la première année de la vie. Cette étude longitudinale prospective a examiné les modèles de continuité au niveau moyen et la stabilité des différences individuelles de certaines échelles de tempérament à 6 et à 12 mois chez les enfants prématurés de trois pays, le Chili (n = 47), le Royaume Uni (n = 44) et les Etats-Unis d'Amérique (n = 50). Le tempérament a été évalué au moyen du Questionnaire du Comportement du Nourrisson et observé en utilisant l'Echelle de Bailey d'Evaluation du Comportement du Nourrisson. La continuité et la stabilité au travers de l'âge du nourrisson, les effets du pays et les interactions du pays et de l'âge sur le tempérament du bébé prématuré ont été examinés. Les mères chiliennes ont évalué leurs bébés plus haut pour ce qui concernait la capacité à être calmé, la durée de l'orientation et l'orientation/l'engagement par comparaison aux mères du Royaume Uni et/ou des Etats-Unis. La continuité du tempérament de 6 à 12 mois a varié par pays: les mères chiliennes ont fait état de plus de sourires et de rires et d'un niveau d'activité plus élevé de 6 à 12 mois et les mères du Royaume Uni ont fait état d'une décroissance des sourires et des rires et d'une plus grande peur de 6 à 12 mois. Le tempérament du nourrisson était stable dans les trois pays. Les corrélations ont montré une concordance faible entre les rapports maternels et les observations de l'examinateur du tempérament du nourrisson à 12 mois. Cependant, chez les enfants chiliens, un niveau d'activité plus élevé rapporté par la mère était lié à un score d'orientation/d'engagement observé plus élevé de la part de l'examinateur.

A Longitudinal Examination of the Family Stress Model of Economic Hardship in Seven Countries.

The Family Stress Model of Economic Hardship (FSM) posits that economic situations create differences in psychosocial outcomes for parents and developmental outcomes for their adolescent children. However, prior studies guided by the FSM have been mostly in high-income countries and have included only mother report or have not disaggregated mother and father report. Our focal research questions were whether the indirect effect of economic hardship on adolescent mental health was mediated by economic pressure, parental depression, dysfunctional dyadic coping, and parenting, and whether these relations differed by culture and mother versus father report. We conducted multiple group serial mediation path models using longitudinal data from adolescents ages 12-15 in 2008-2012 from 1,082 families in 10 cultural groups in seven countries (Colombia, Italy, Jordan, Kenya, the Philippines, Thailand, and the United States). Taken together, the indirect effect findings suggest partial support for the FSM in most cultural groups across study countries. We found associations among economic hardship, parental depression, parenting, and adolescent internalizing and externalizing. Findings support polices and interventions aimed at disrupting each path in the model to mitigate the effects of economic hardship on parental depression, harsh parenting, and adolescents' externalizing and internalizing problems.

Prospective associations between mothers' and fathers' parenting styles and adolescents' moral values: Stability and specificity by parent style and adolescent gender.

This study coordinates moral value development in adolescence, parenting style, and gender with issues of stability and specificity. The primary research question asked whether parenting styles of mothers and fathers influence the development of adolescent moral values, and secondary research questions asked whether adolescent moral values were stable and whether gender moderated predictive relations of parenting styles and adolescent moral values. At 14 and 18 years, a sample of 246 adolescents completed the Sociomoral Reflection Objective Measure - Short Form; at 14 years, mothers and fathers self-reported their parenting styles using the Parental Authority Questionnaire. Exploratory and confirmatory factor analyses established a 2-factor model of adolescent moral values across the two ages: Life and Social Contract captured prosocial aspects of morality that are left to individual choice, and Law and Social Order captured acts that are legally or morally obligatory for individuals to perform. Structural equation modeling investigated relations between parental parenting styles and the two adolescent moral value factors, with adolescent age, gender, and family SES as covariates. Both moral values factors had high stabilities across the 4-year period. Mothers' authoritarian parenting at 14 years, but not their authoritative or permissive parenting, negatively predicted Life and Social Contract moral values, but not Law and Social Order, in adolescents at 18 years, more so for boys. Fathers' parenting styles did not predict adolescents' moral values at 18 years. Girls and adolescents from higher-SES families had higher Life and Social Contract moral values at 14 years; boys experienced more increases in Life and Social Contract moral values from 14 to 18 years than girls. Stability and parental predictive validity of moral values for adolescence are discussed.

The Specificity Principle in Young Dual Language Learners' English Development.

This study employs the Specificity Principle to examine the relative impacts of external (input quantity at home and at school, number of books and reading frequency at home, teachers' degree and experience, language usage, socioeconomic status) and internal factors (children's working memory, nonverbal intelligence, learning-related social-skills, chronological age, gender) on children's English-language development in phonological awareness (PA), receptive vocabulary (RV), and word reading (WR). Altogether, 736 four- to five-year-old Singaporean Mandarin-English speaking kindergarteners were assessed twice longitudinally. Their English-language PA, RV, and WR development was predicted using the eight external factors and five internal factors with Bayesian least absolute shrinkage and selection operators. Internal factors explained more variance than external factors in all three language domains. External factors had their largest impact on RV.
