Although it is known from epidemiological research that girls are more likely to develop internalizing disorders and boys are more likely to develop externalizing disorders, differences between girls and boys are rarely examined in risk research. This longitudinal study of 356 families identified risk factors for the development of externalizing…

Extensive evidence and theory suggest that the development of motor skills during infancy and early childhood initiates a "developmental cascade" for cognitive abilities, such as reading and math. Motor skills are closely connected with the development of spatial cognition, an ability that supports deductive reasoning. Despite the…

'High functioning autism' is a term often used for individuals with autism spectrum disorder without an intellectual disability. Over time, this term has become synonymous with expectations of greater functional skills and better long-term outcomes, despite contradictory clinical observations. This study investigated the relationship between…

Background: This study examined the relation between three variables related to adoptive family relationships (post-adoption contact between adoptive and birth family members, adoption communicative openness, and satisfaction with contact) and adoptee externalizing behavior in adolescence and emerging adulthood. Method: The study included 190…

The purpose of this paper is to provide a comprehensive review of the empirical findings on the stability of attachment from infancy through adulthood. More specifically, the paper discusses the longitudinal research concerning the continuity of attachment from infancy to adulthood as well as those studies that have assessed stability within a…

This study examined the association between fathers' and mothers' risk factors and paternal engagement 1 and 3 years postbirth. Distinguishing between new and persistent risk factors, we tested whether cumulative risk has unique effects on couples where one or both parents are adolescents at birth. Results indicated that although fathers' and…

Objective: To identify predictors and moderators of outcome in the first Pediatric OCD Treatment Study (POTS I) among youth (N = 112) randomly assigned to sertraline, cognitive behavioral therapy (CBT), both sertraline and CBT (COMB), or a pill placebo. Method: Potential baseline predictors and moderators were identified by literature review. The…

Research has shown a strong connection between birth weight and future outcomes. We ask how health problems after birth affect outcomes using data from public health insurance records for 50,000 children born between 1979 and 1987 in the Canadian province of Manitoba. We compare children to siblings born an average of three years apart. We find…

This book contains a compilation of papers presented at the International Psychological Applications Conference and Trends (InPACT) 2018, organized by the World Institute for Advanced Research and Science (W.I.A.R.S.). Modern psychology offers a large range of scientific fields where it can be applied. The goal of understanding individuals and…

A total of 133 children was assessed at ages one, two, three, four, and five, in the teen period, and in young adulthood. Difficult/easy temperament scores in the earlier periods were compared with the later young adult scores. Ages three and four were found to be better predictors of young adults' temperament than were ages one, two, and five.…

Among girls observed interacting with infants, older girls ignored more, made fewer social bids, and responded less than younger girls. However, chronological age was highly correlated with measures of social and biological maturity. Social maturity was the best predictor of trends on two interaction measures, biological maturity on the third.…

Examined relations between infant security of attachment, negative life events, and adolescent attachment classification in sample from the Family Lifestyles Project. Found that stability of attachment classification was 77 percent. Infant attachment classification predicted adolescent attachment classification. Found no differences between…

Background: This study examined the effects of maternal anger, partner transitions and partner conflict on later oppositional and angry behavior of the children of teenage mothers. Methods: One hundred and twenty-one teenage women were interviewed prior to the birth of the baby and at 3 points subsequently, when children were newborn, 7 years old…

This longitudinal study investigated the relative contributions of infant temperament, maternal sensitivity, and psychosocial risk to individual differences in preschool children's cognitive development. It also examined specific moderating effects between predictors as well as the specific mediating role of maternal sensitivity in the relation…

This study examined differences between the positive mother-infant interactions of adolescents and those of young adult mothers, both before and after controlling for socioeconomic status (SES) and educational level. The study also investigated factors related to adolescents' early and later maternal-infant interaction patterns. Subjects were 100…
