Short-term Longitudinal Study (short-term + longitudinal_study)
Selected AbstractsSleep arrangements and night waking at 6 and 12 months in relation to infants' stress-induced cortisol responsesINFANT AND CHILD DEVELOPMENT, Issue 6 2009Rachel Lucas-Thompson Abstract The objective of this short-term longitudinal study was to examine the concurrent and prospective associations of infants' sleep arrangements and night waking with cortisol responses to an inoculation at 6 and 12 months, controlling for several key covariates. To our knowledge, this was the first study to concurrently and prospectively link proximity in sleep arrangements and night waking to physiological stress reactivity. A sample of 92 mother,infant dyads participated in the study when the infants were 6 and 12 months of age, although sample sizes were reduced for some analyses. Both proximal cosleeping arrangements and more frequent night wakings' were associated concurrently with an increased cortisol response to inoculations at both ages. Night waking at 6 months also was associated with a slightly increased cortisol response to inoculation at 12 months. Results aimed at exploring the direction of influence suggested that cosleeping and night waking may influence infant stress physiology rather than the reverse. Adaptive and maladaptive implications of infants' nocturnal experiences and greater stress-induced cortisol responses are discussed. Copyright © 2009 John Wiley & Sons, Ltd. [source] Shyness as a continuous dimension and emergent literacy in young children: is there a relation?INFANT AND CHILD DEVELOPMENT, Issue 3 2009Katherine Spere Abstract The present study assessed 89 children in a short-term longitudinal study from Junior Kindergarten (age 4,5 years) through Grade 1 (age 6,7 years) using a variety of tests of emergent literacy. Children were assessed for reading skill (a composite of word recognition, decoding, and letter-sound knowledge), phonological awareness, and oral language (i.e. both receptive and expressive vocabulary as well as syntax and fluency). Shyness was treated as a continuous variable rather than contrasting extreme groups of shy and non-shy children. Shyness was modestly related to vocabulary, verbal fluency, and phonological awareness. Results suggest that among young children the association of greater shyness with compromised skill development potentially extends beyond the vocabulary domain to include emergent literacy more broadly.

[source] The influence of infant irritability on maternal sensitivity in a sample of very premature infantsINFANT AND CHILD DEVELOPMENT, Issue 2 2003Petra Meier Abstract The relationship between maternal sensitivity and infant irritability was investigated in a short-term longitudinal study of 29 very preterm infants. Infant irritability was assessed at term with the Brazelton NBAS, the Mother and Baby Scales (MABS) and the Crying Pattern Questionnaire (CPQ). Maternal sensitivity was assessed by nurses' ratings in the neonatal care unit and at three months during mother,infant interaction observation. Cross-lagged panel analysis indicated that neonatal irritability did not influence sensitivity at 3 months nor did maternal sensitivity in the newborn period lead to reduced irritability at 3 months. Both irritability and maternal sensitivity showed moderate stability over time (r = 0.55 and r = 0.60, respectively). It is concluded that in early infancy maternal sensitivity shows little influence on infant irritability in very preterm infants. Copyright © 2003 John Wiley & Sons, Ltd. [source] The differential effects of parental divorce and marital conflict on young adult romantic relationshipsPERSONAL RELATIONSHIPS, Issue 3 2010MING CUI The differential effects of parental divorce and marital conflict on young adult children's romantic relationships were examined in this short-term longitudinal study. Using a sample of 285 young adults, structural equation modeling supported the hypothesis that parental divorce and marital conflict were independently associated with young adult children's romantic relationships through different mechanisms: Parental divorce was associated with young adults' low level of relationship quality through a negative attitude toward marriage (positive attitude toward divorce) and lack of commitment to their own current relationships. However, marital conflict was associated with young adults' low level of relationship quality through their conflict behavior with their partner. These findings are discussed in terms of their implications for future research. [source] Psychosocial Antecedents of Variation in Girls' Pubertal Timing: Maternal Depression, Stepfather Presence, and Marital and Family StressCHILD DEVELOPMENT, Issue 2 2000Bruce J. Ellis Drawing on Belsky, Steinberg, and Draper's evolutionary theory of the development of reproductive strategies, we tested a model of individual differences in girls' pubertal timing. This model posits that a history of psychopathology in mothers results in earlier pubertal maturation in daughters, and that this effect is mediated by discordant family relationships and father absence/stepfather presence. The model was supported in a short-term longitudinal study of 87 adolescent girls. In the primary test of the model, it was found that a history of mood disorders in mothers predicted earlier pubertal timing in daughters, and this relation was fully mediated by dyadic stress and biological father absence. In families in which the mother's romantic partner was not the biological father, dyadic stress accounted for almost half of the variation in daughters' pubertal timing. Stepfather presence, rather than biological father absence, best accounted for earlier pubertal maturation in girls living apart from their biological fathers. We propose that stepfather presence and stressful family relationships constitute separate paths to early pubertal maturation in girls. [source] | ||||||||||
