DBT-A may be an effective intervention to reduce self-harm, suicidal ideation, and depression in adolescents with repetitive self-harming behavior. Clinical trial registration information-Treatment for Adolescents With Deliberate Self Harm; http://ClinicalTrials.gov/; NCT00675129.

This retrospective chart review study of 227 participants examined the psychiatric profiles of outpatient adolescents ages 12 to 19 years (M = 15.08 years, SD = 1.72 years) engaging in different types of deliberate self-harm (DSH) behaviors. Participants were divided into four groups: no deliberate self-harm (NoDSH; n = 119), nonsuicidal self-injury only (NSSI only; n = 30), suicide attempt only (n = 38), and suicide attempt plus NSSI (n = 40). Those who attempted suicide were more likely to have major depressive disorder and/or posttraumatic stress disorder than those who engaged in NSSI only. Those who engaged in any type of DSH were more likely to have features of borderline personality disorder than those who did not engage in DSH. The suicidal ideation levels of those in the NSSI group were similar to those in the NoDSH group. Findings offer empirical support for the importance of distinguishing between suicidal and nonsuicidal self-harm behaviors.

Resilience theory provides a framework for studying and understanding how some youths overcome risk exposure and guides the development of interventions for prevention using a strengths-based approach. In this article, we describe basic concepts of the theory, such as promotive factors, and distinguish assets and resources that help youths overcome the negative effects of risk exposure. We also present three models of resilience theory—compensatory, protective, and challenge—and review empirical research on three promotive factors—ethnic identity, social support, and prosocial involvement—that include individual, family, and community levels of analysis and have modifiable qualities for informing interventions. Finally, we present examples of how research findings from the three promotive factors can be translated into interventions to enhance youth development.

Objective Examine associations of maternal mobile device use with the frequency of mother-child interactions during a structured laboratory task. Methods Participants included 225 low-income mother-child pairs. When children were ~6 years old, dyads were videotaped during a standardized protocol in order to characterize how mothers and children interacted when asked to try familiar and unfamiliar foods. From videotapes, we dichotomized mothers based on whether or not they spontaneously used a mobile device, and counted maternal verbal and nonverbal prompts toward the child. We used multivariate Poisson regression to study associations of device use with eating prompt frequency for different foods. Results Mothers were an average of 31.3 (SD 7.1) years old and 28.0% were of Hispanic/non-white race/ethnicity. During the protocol, 23.1% of mothers spontaneously used a mobile device. Device use was not associated with any maternal characteristics, including age, race/ethnicity, education, depressive symptoms, or parenting style. Mothers with device use initiated fewer verbal (RR 0.80 [95% CI: 0.63, 1.03]) and nonverbal (0.61 [0.39, 0.96]) interactions with their children than mothers who did not use a device, when averaged across all foods. This association was strongest during introduction of halva, the most unfamiliar food (0.67 [0.48, 0.93] for verbal and 0.42 [0.20, 0.89] for nonverbal interactions). Conclusions Mobile device use was common and associated with fewer interactions with children during a structured interaction task, particularly nonverbal interactions and during introduction of an unfamiliar food. More research is needed to understand how device use affects parent-child engagement in naturalistic contexts.

Purpose of review To highlight the recent findings on sleep–obesity associations in children. We focus on sleep duration, sleep timing and chronotype, and describe the potential mechanisms underlying sleep–obesity associations. Recent findings Poor sleep is increasingly common in children and associations between short sleep duration in early childhood and obesity are consistently found. Less is known about the infancy period, and the findings in adolescents are inconsistent. Sleep timing patterns may also contribute to obesity risk. Variable and shifted sleep schedules and evening chronotypes have recently been linked to adiposity in adults; less is known about children. Further, there is little understanding regarding the mechanisms of association. The timing of eating, dietary intake, obesogenic eating behaviors, and changes in appetite-regulating hormones have been identified as possible mechanisms for sleep–obesity associations and may be promising avenues for future research. Longitudinal and experimental work with children is needed to determine the nature of associations. Summary Beyond sleep duration, sleep timing patterns may contribute to obesity risk. Biological and behavioral processes have been proposed as mechanisms that may explain the association. Understanding the pathways through which poor sleep patterns could increase obesity risk in children may provide novel avenues for intervention.

SUMMARY Early childhood is a period of dramatic change in sleep and emotion processing, as well as a time when disturbance in both domains are first detected. Although sleep is recognized as central in emotion processing and psychopathology, the great majority of experimental data have been collected in adults. We examined the effects of acute sleep restriction (nap deprivation) on toddlers’ emotion expression. Ten healthy children (7 females; 30–36 months) followed a strict sleep schedule (≥12.5 hrs time in bed/24 hrs) for 5 days before each of two randomly-assigned afternoon emotion assessments following Nap and No-Nap conditions (resulting in an 11-day protocol). Children viewed emotion-eliciting pictures (5 positive, 3 neutral, 3 negative) and completed puzzles (1 solvable, 1 unsolvable). Children’s faces were video-recorded, and emotion displays were coded. When sleep restricted, children displayed less confusion in response to neutral pictures, more negativity to neutral and negative pictures, and less positivity to positive pictures. Sleep restriction also resulted in a 34% reduction in positive emotion responses (solvable puzzle), as well as a 31% increase in negative emotion responses and a 39% decrease in confused responses (unsolvable puzzle). These findings suggest sleep is a key factor in how young children respond to their world. When sleep restricted, toddlers are neither able to take full advantage of positive experiences nor are they as adaptive in challenging contexts. If insufficient sleep consistently “taxes” young children’s emotion responses, they may not manage emotion regulation challenges effectively, potentially placing them at risk for future emotional/behavioral problems.

Jealousy is a social emotion that has received little attention by developmental researchers. The current study examined sibling jealousy and its relations to child and family characteristics in 60 families with a 16-month-old toddler and an older preschool-age sibling. Sibling jealousy was elicited in social triads consisting of a parent (mother or father) and the two siblings. Positive marital relationship quality (i.e., love and relationship maintenance) was a particularly strong predictor of the older siblings' abilities to regulate jealousy reactions in the mother sessions. Younger siblings' jealous affect with mothers was linked to the child's temperament, whereas older siblings' jealous affect with mothers was related to the child's emotional understanding. Younger siblings displayed more behavioral dysregulation in the mother-sibling triads if there was greater sibling rivalry reported by mothers. Session order (i.e., which sibling was challenged first in the jealousy paradigm) had a strong effect on both the affect and behavioral dysregulation displayed by the older and younger siblings. Results are discussed with respect to the need for future research to consider social relationships as developmental contexts for young children's emotion regulation.
