Forensic interviewers are encouraged to elicit a practice narrative from children in order to train them to answer free recall questions with narrative information. Although asking children about their last birthday has been recommended, concerns have been raised that many children will have nothing to report. This study asked 994 4- to 9-year-old maltreated and non-maltreated children to recall their last birthday. Although a fair number of children initially failed to recall information (9%), virtually all children recalled information with persistent encouragement (99%). Younger children and maltreated children were less responsive and spoke less, but nevertheless, 93% of the youngest children (4-year-olds) and 97% of maltreated children recalled information with persistent encouragement. The results suggest that children's failures to recall information about birthdays are predominantly attributable to a failure to provide additional support.

Encouraging involvement in school-based extracurricular activities (ECA) may be important for preventing high school dropout. However, the potential of these activities remains underexploited, perhaps because studies linking ECA involvement and dropout are rare and based on decades-old data. Previous studies also ignore key parameters of student involvement. The present study expands and updates this limited literature by using recent data from a high-risk Canadian sample (N = 545) and by considering a range of involvement parameters. Results showed that consistent involvement in the past year was associated with lower odds of dropout (OR = 0.32; 95% CI = 0.17-0.61). However, adolescents who interrupted their involvement during this period (e.g., because of cancelations or exclusions) were as much at risk of dropout as those who were not involved at all. Findings notably imply that excluding students from ECA (e.g., because of No Pass/No Play policies) may heighten their dropout risk.

Parents are important for the development and maintenance of regulatory control. The current longitudinal study examined associations between parental coercion and autonomy support and impulse control in 117 youth (ages 8-16; M_age= 12.87, SD=2.53; 44% male) with Type 1 diabetes and explored whether youth negative affect mediated these associations. Parental coercion (but not autonomy support) was concurrently associated with lower impulse control and higher negative affect within individuals. Increases in youth negative affect partially mediated the within-person association between parental coercion and impulse control. These findings suggest that parent-directed interventions to reduce parental coercion may be most beneficial for impulse control if combined with youth-directed interventions to help them regulate negative affect. Replication of the current findings in a larger sample of youth with and without a chronic illness is needed to address the theoretical and empirical importance of negative affect as a potential mechanism through which parental coercion impacts youth impulsivity.

With growing attention to youth's efforts to address sexual and gender diversity issues in Gender-Sexuality Alliances (GSAs), there remains limited research on adult advisors. Do advisor characteristics predict their youth members' advocacy? Among 58 advisors of 38 GSAs, we considered whether advisor attributes predicted greater advocacy by youth in these GSAs (n = 366) over the school year. GSAs varied in youth advocacy over the year. Youth in GSAs whose advisors reported longer years of service, devoted more time to GSA efforts each week, and employed more structure to meetings (to a point, with a curvilinear effect), reported greater relative increases in advocacy over the year (adjusting for initial advocacy and total meetings that year). Relative changes in advocacy were not associated with whether advisors received a stipend, training, or whether GSAs had co-advisors. Continued research should consider how advisors of GSAs and other social justice-oriented groups foster youth advocacy.

Play during childhood is essential to growth and learning. Little is known about whether categories of toys moderate play behaviors at different ages, or how children interact with toys that are simple, appropriate, or complex for their developmental level. Two hundred and forty-three children between the ages of 1 and 8 years, divided into four age groups, played with toys that were targeted to their age group as well as toys aimed at one age group younger and older. Toys fell into nine different categories. Whether children fully utilized each toy was evaluated. Analyses examined how children's utilization of toys was affected by the age-appropriateness of the toy, the category of toy, and the child's age. Considering all age groups and toys, children were less likely to fully utilize toys targeted toward older children than age-appropriate toys, but this effect was moderated by the toy category and the child's age.

The integration of neurodevelopmental perspectives into clinical science has identified irritability as an early dimensional marker of lifespan mental health risk. Elucidating the developmental patterning of irritable behavior is key to differentiating normative variation from risk markers. Accounting for dysregulation and contextual features of irritability is useful for differentiation at preschool age, laying the groundwork for even earlier characterization. We provide initial evidence for the validity of the Multidimensional Assessment Profile of Disruptive Behavior Temper Loss Scale, Infant-Toddler version in two independent samples of 12-18-month-olds from the US. We calibrated the measure using item response theory in a large representative sample, then validated within an independent sample. We characterized the developmental patterning of irritable behaviors and their dimensional spectrum, and demonstrated test-retest reliability, and convergent validity. The MAP-DB-IT is a standardized, dimensional survey assessing irritability that serves as a tool for characterizing the developmental expression of early mental health risk.
