Self-Regulation Development Among Young Spanish-English Dual Language Learners.

Despite strong evidence self-regulation skills are critical for school readiness, there remains a dearth of longitudinal studies that describe developmental trajectories of self-regulation, particularly among low-resource and underrepresented populations such as Spanish-English dual-language learners (DLLs). The present study examined individual differences in trajectories of self-regulation among 459 Spanish-English DLLs who were Hispanic from four different samples and three geographic locations in the U.S.

Fathering quality in early childhood and kindergarten achievement in low-income racial-ethnic minority children.

The relative lack of attention to fathers' effects on children's achievement is even more apparent when examining fathering among low-income racial-ethnic minorities. We examined relations of fathering qualities when children were 2-3 years old with subsequent reading and mathematics achievement in kindergarten in a sample of low-income African American (n = 119) and primarily Mexican-origin Latino children (n = 193) from multiple neighborhood areas of a large city in the southwestern United States. Measures of parenting qualities were based on qualitative ratings of videotaped observations of father-child and mother-child interactions collected in the home during semistructured play activities.

Sending and Receiving Text Messages with Sexual Content: Relations with Early Sexual Activity and Borderline Personality Features in Late Adolescence.

This research examined adolescents' written text messages with sexual content to investigate how sexting relates to sexual activity and borderline personality features. Participants (N = 181, 85 girls) completed a measure of borderline personality features prior to 10 grade and were subsequently given smartphones configured to capture the content of their text messages. Four days of text messaging were micro-coded for content related to sex.

The BlackBerry Project: The Hidden World of Adolescents' Text Messaging and Relations With Internalizing Symptoms.

In this naturalistic study of adolescents' text messaging, participants ( = 172, 81 girls, age 14) were given BlackBerry devices configured to save their text messages to a secure archive for coding. Two, 2-day transcripts collected four months apart within the same academic year were microcoded for content. Results showed that most text message utterances were positive or neutral, and that adolescents sent text messages primarily to peers and to romantic partners.

Family predictors of continuity and change in social and physical aggression from ages 9 to 18.

This research examined developmental trajectories for social and physical aggression for a sample followed from age 9 to 18, and investigated possible family predictors of following different trajectory groups. Participants were 158 girls and 138 boys, their teachers, and their parents (21% African American, 5.3% Asian, 51.
