RESUMO
Consistency in the order of individuals in a group across substantial lengths of time-stability-is a central concept in developmental science for several reasons. Stability underscores the meaningfulness of individual differences in psychological phenomena; stability informs about the origins, nature, and overall developmental course of psychological phenomena; stability signals individual status and so affects the environment, experience, and development; stability has both theoretical and clinical implications for individual functioning; and stability helps to establish that a measure constitutes a consequential individual-differences metric. In this three-wave prospective longitudinal study (Ns = 40 infants and mothers), we examined stabilities of individual variation in multiple infant behaviors and maternal responses to them across infant ages 10, 14, and 21 months. Medium to large effect size stabilities in infant behaviors and maternal responses emerged, but both betray substantial amounts of unshared variance. Documenting the ontogenetic trajectories of infant behaviors and maternal responses helps to elucidate the nature and structure of early human development.

Consistency in the order of individuals in a group across short periods of time-reliability-is both important developmentally and meaningful psychologically. For example, documenting the reliabilities of infant behaviors and maternal parenting practices elucidates the nature and structure of early development. In this prospective short-term longitudinal study (Nsâ¯=â¯51 5-month infants and their mothers), we examined reliabilities of individual variation in multiple infant behaviors (physical development, social interaction, exploration, nondistress vocalization, and distress communication) and maternal parenting practices (nurturing, encouragement of motor growth, social exchange, didactic interaction, provision of the material environment, and speech to infant). Medium to large effect size reliabilities characterize infant behaviors and maternal parenting practices, but both betray substantial amounts of unshared variance. Established reliability is essential to the application of these measures in infancy studies, it is central to replication, and it is a limiting factor in predictive validity.

Beliefs about child competence in math and reading have important implications for academic performance in adolescence. However, it is unclear whether children's own beliefs are the most important predictor of their academic performance or whether parents' and teachers' beliefs about child competence influence child academic performance. We assessed mothers', fathers', teachers', and children's beliefs about European American children's (N = 189) competence in math and reading at age 10 and children's math and language performance at ages 10, 13, and 18 years. Confirmatory factor models demonstrated that children's and teachers' beliefs had lower loadings on a latent variable of child competence in math and reading than mothers' beliefs. Children's self-competence beliefs in math and reading were not significantly correlated, suggesting children may use dimensional comparisons when assessing their own competence. Mothers', fathers', and teachers' assessments of child competence in math were strongly correlated with their assessments of child competence in reading. Controlling for stability in academic performance, family socioeconomic status, and other reporters, mothers and fathers who rated their children's math competence higher had adolescents who performed better in math, and fathers who rated their children's reading competence higher had adolescents who performed better in language tasks. However, children who rated their own competence higher in math and reading had lower math and language (for girls only) performance in adolescence. European American children may use dimensional comparisons that render them poorer judges of their math and reading competence than parents.

BACKGROUND: Self-concept has meaningful relations with psychological functioning and well-being across the life span. Hence, it is important to understand how and when individual differences in multiple domains of self-concept begin to stabilize and whether individual differences remain stable throughout childhood and adolescence and into early adulthood. METHODS: We assessed individuals' (N = 372) scholastic, social, athletic, and physical appearance self-concepts at five waves over 20 years from age 4 to age 24. RESULTS: In general, stability was large, but medium-sized estimates were obtained for some domains over longer (e.g., 6-year) intervals. Indirect effects from preschool to early adulthood were small, but from age 14 to 24 were medium to large. Stabilities maintained significance independent of family socioeconomic status and global self-worth. Stability estimates were similar for boys and girls except over adolescence for scholastic self-concept, which was more stable for girls than boys. CONCLUSIONS: Multiple domains of self-concept constitute stable individual-difference characteristics, independent of global feelings of self-worth. Individuals who have high or low self-concepts early in development tend to maintain their relative standing into early adulthood suggesting points of intervention.

This 3-wave longitudinal study focuses on stability of child temperament from 3 to 6 years and considers child age, gender, birth order, and term status as well as mother age, education, anxiety, and depression as moderators of stability. Mothers of approximately 10,000 children participating in the Avon Longitudinal Study of Parents and Children rated child temperament. Stability coefficients for child temperament scales were medium to large, and stability was generally robust across moderators except child gender and birth order and mother age and education, which had small moderating effects on reports of stability of child temperament. Statement of contribution What is already known on this subject? Some is known about the stability of temperament in infancy in small samples, but much less is known about the stability of temperament in early childhood or its moderation. What does this study add? This study uses a large sample (Ë10,000) to trace the stability of temperament from 3 to 6 years in three waves and considers child age, gender, birth order, and term status as well as mother age, education, anxiety, and depression as moderators of stability.

Command of language is a fundamental life skill, a cornerstone of cognitive and socioemotional development, and a necessary ingredient for successful functioning in society. We used 15-year prospective longitudinal data from the Avon Longitudinal Study of Parents and Children to evaluate two types of stability of core language skill in 5036 typically developing and 1056 atypically developing (preterm, dyslexic, autistic, and hearing impaired) children in a multiage, multidomain, multimeasure, multireporter framework. A single core language skill was extracted from multiple measures at multiple ages, and this skill proved stable from infancy to adolescence in all groups, even accounting for child nonverbal intelligence and sociability and maternal age and education. Language skill is a highly conserved and robust individual-differences characteristic. Lagging language skills, a risk factor in child development, would profitably be addressed early in life.

BACKGROUND: Command of language is a fundamental skill, a cornerstone of multiple cognitive and socioemotional aspects of development, and a necessary ingredient of successful adjustment and functioning in society. Little is known about the developmental stability of language in at-risk youth or which biological and social risk factors moderate stability. METHODS: This four-wave 10-year prospective longitudinal study evaluated stability of core language skill in 1,780 children in varying categories of biological and social risk in a multiage, multidomain, multimeasure, and multireporter framework. RESULTS: Structural equation modeling supported loadings of diverse age-appropriate measures of child language on single latent variables of core language skill at 15 and 25 months and 5 and 11 years, respectively. Core language skill was stable over the first decade of life; significant and comparable stability coefficients were obtained for children with diverse biological and social risks, including poor health, welfare status, teen motherhood, ethnicity, gender, birth order, and families that changed in income and maternal education over the study period; stability in language was strong even accounting for child nonverbal intelligence and social competence, maternal education and language, and the family home environment. CONCLUSIONS: Core language skill varies in stability with age but is robustly stable in children regardless of multiple biological and social risk factors.

This 4-wave longitudinal study evaluated stability of core language skill in 421 European American and African American children, half of whom were identified as low (n = 201) and half of whom were average-to-high (n = 220) in later language skill. Structural equation modeling supported loadings of multivariate age-appropriate multisource measures of child language on single latent variables of core language skill at 15 and 25 months and 5 and 11 years. Significant stability coefficients were obtained between language latent variables for children of low and average-to-high language skill, even accounting for child positive social interaction and nonverbal intelligence, maternal education and language, and family home environment. Prospects for children with different language skills and intervention implications are discussed. (PsycINFO Database Record

Two complementary studies focused on stability of infant temperament across the 1st year and considered infant age, gender, birth order, term status, and socioeconomic status (SES) as moderators. Study 1 consisted of 73 mothers of firstborn term girls and boys queried at 2, 5, and 13 months of age. Study 2 consisted of 335 mothers of infants of different gender, birth order, term status, and SES queried at 6 and 12 months. Consistent positive and negative affectivity factors emerged at all time points across both studies. Infant temperament proved stable and robust across gender, birth order, term status, and SES. Stability coefficients for temperament factors and scales were medium to large for shorter (< 9 months) interassessment intervals and small to medium for longer (> 10 months) intervals.

This four-wave prospective longitudinal study evaluated stability of language in 324 children from early childhood to adolescence. Structural equation modeling supported loadings of multiple age-appropriate multisource measures of child language on single-factor core language skills at 20 months and 4, 10, and 14 years. Large stability coefficients (standardized indirect effect = .46) were obtained between language latent variables from early childhood to adolescence even when accounting for child nonverbal intelligence and social competence and maternal verbal intelligence, education, speech, and social desirability. Stability coefficients were similar for girls and boys. Stability of core language skill was stronger from 4 to 10 to 14 years than from 20 months to 4 years, so early intervention to improve lagging language is recommended.

A developmental cascade defines a longitudinal relation in which one psychological characteristic uniquely affects another psychological characteristic later in time, separately from other intrapersonal and extrapersonal factors. Here, we report results of a large-scale (N = 374), normative, prospective, 14-year longitudinal, multivariate, multisource, controlled study of a developmental cascade from infant motor-exploratory competence at 5 months to adolescent academic achievement at 14 years, through conceptually related and age-appropriate measures of psychometric intelligence at 4 and 10 years and academic achievement at 10 years. This developmental cascade applied equally to girls and boys and was independent of children's behavioral adjustment and social competence; mothers' supportive caregiving, verbal intelligence, education, and parenting knowledge; and the material home environment. Infants who were more motorically mature and who explored more actively at 5 months of age achieved higher academic levels as 14-year-olds.

Two independent prospective longitudinal studies that cumulatively spanned the age interval from 4 years to 14 years used multiwave designs to investigate developmental associations between language and behavioral adjustment (internalizing and externalizing behavior problems). Altogether 224 children, their mothers, and teachers provided data. Series of nested path analysis models were used to determine the most parsimonious and plausible paths among the three constructs over and above stability in each across age and their covariation at each age. In both studies, children with poorer language skills in early childhood had more internalizing behavior problems in later childhood and in early adolescence. These developmental paths between language and behavioral adjustment held after taking into consideration children's nonverbal intellectual functioning, maternal verbal intelligence, education, parenting knowledge, and social desirability bias, as well as family socioeconomic status, and they applied equally to girls and boys.

A developmental cascade describes a longitudinal cross-domain unique relation. Here, a 3-wave multivariate design and developmental cascade analysis were used to investigate pathways among adaptive functioning and externalizing and internalizing behavioral problems in a community sample of 134 children seen at 4, 10, and 14 years. Children, mothers, and teachers provided data. Nested path analytic models tested the plausible cascades among the three domains apart from their covariation at each age and rank-order stability across age. Adaptive functioning in early adolescence was predicted by early childhood adaptive functioning and externalizing behavioral problems, with both effects mediated by late childhood adaptive functioning and internalizing behavioral problems; externalizing behavioral problems in early adolescence were predicted by early childhood internalizing behavioral problems with the effect mediated by late childhood externalizing behavioral problems. These developmental cascades obtained independent of child intelligence; child age and maternal education and social desirability were also considered but were not related to any outcome variables. The findings suggest that strategically timed and targeted interventions designed to address young children's behavioral problems may return investment in terms of an enhanced epidemiology of adaptively functioning teens.
RESUMO
A large-scale (N = 552) controlled multivariate prospective 14-year longitudinal study of a developmental cascade embedded in a developmental system showed that information-processing efficiency in infancy (4 months), general mental development in toddlerhood (18 months), behavior difficulties in early childhood (36 months), psychometric intelligence in middle childhood (8 years), and maternal education either directly or indirectly (or both) contribute to academic achievement in adolescence (14 years).

A community sample of 262 European American mothers of firstborn 20-month-olds completed a personality inventory and measures of parenting cognitions (knowledge, self-perceptions, and reports about behavior) and was observed in interaction with their children from which measures of parenting practices (language, sensitivity, affection, and play) were independently coded. Factor analyses of the personality inventory replicated extraction of the 5-factor model of personality (Openness, Neuroticism, Extraversion, Agreeableness, and Conscientiousness). When controlling for sociodemographic characteristics, the 5 personality factors qua variables and in patterns qua clusters related differently to diverse parenting cognitions and practices, supporting the multidimensional, modular, and specific nature of parenting. Maternal personality in the normal range, a theoretically important but empirically neglected factor in everyday parenting, has meaning in studies of parenting, child development, and family process.

Emotional availability (EA) is a prominent index of mutual socioemotional adaptation in the parent-infant dyad. This study examines zero-order and unique associations of multiple maternal and infant behavior and context indicators to variation in aspects of EA in mothers and their young infants. The associations to each were explored in separate analyses for maternal sensitivity and infant responsiveness in 369 European American mothers and their firstborn 5½-month-olds. Beyond zero-order relations, robust regression analyses revealed differentiated patterns of unique relations of mother and infant behavior and context indicators to the EA dimensions of maternal sensitivity and infant responsiveness. Although potential behavior and context relations to EA are many, prominent relations to maternal sensitivity and infant responsiveness are few, and patterns of association vary for the two dimensions of EA. Adequate EA is fundamental to a healthy parent-infant relationship, and understanding the behavior and context indicators associated with EA is fundamental to its enhancement.
RESUMO
This study used a three-wave longitudinal design to investigate developmental cascades among social competence and externalizing and internalizing behavioral adjustment in a normative sample of 117 children seen at 4, 10, and 14 years. Children, mothers, and teachers provided data. A series of nested path analysis models was used to determine the most parsimonious and plausible cascades across the three constructs over and above their covariation at each age and stability across age. Children with lower social competence at age 4 years exhibited more externalizing and internalizing behaviors at age 10 years and more externalizing behaviors at age 14 years. Children with lower social competence at age 4 years also exhibited more internalizing behaviors at age 10 years and more internalizing behaviors at age 14 years. Children who exhibited more internalizing behaviors at age 4 years exhibited more internalizing behaviors at age 10 years and more externalizing behaviors at age 14 years. These cascades among social competence and behavioral adjustment obtained independent of child intelligence and maternal education and social desirability of responding.

Knowledge of child rearing and child development is relevant to parenting and the well-being of children. Using a sociodemographically heterogeneous sample of 268 European American mothers of 2-year-olds, we assessed the state of mothers' parenting knowledge; compared parenting knowledge in groups of mothers who varied in terms of parenthood and social status; and identified principal sources of mothers' parenting knowledge in terms of social factors, parenting supports, and formal classes. On the whole, European American mothers demonstrated fair but less than complete basic parenting knowledge; age, education, and rated helpfulness of written materials each uniquely contributed to mothers' knowledge. Adult mothers scored higher than adolescent mothers, and mothers improved in their knowledge of parenting from their first to their second child (and were stable across time). No differences were found between mothers of girls and boys, mothers who varied in employment status, or birth and adoptive mothers. The implications of variation in parenting knowledge and its sources for parenting education and clinical interactions with parents are discussed.

Responsiveness defines the prompt, contingent, and appropriate reactions parents display to their children in the context of everyday exchanges. Maternal responsiveness occupies a theoretically central position in developmental science and possesses meaningful predictive validity over diverse domains of children's development, yet basic psychometric features of maternal responsiveness are still poorly understood. In this prospective longitudinal study, the authors examined structure, individual variation, and continuity of multiple dimensions of responsiveness in 40 mothers to their infants' activities at 10, 14, and 21 months during natural home-based play interactions. Both age-general and age-specific patterns emerged in maternal responding. The study's developmental results support the multidimensionality, modularity, and specificity of this central parenting construct.
