Identifying Children at Risk of Problematic Development: Latent Clusters Among Childhood Arrestees

The presence of clusters characterized by distinct profiles of individual, family and peer characteristics among childhood arrestees was investigated and cluster membership stability after 2 years was determined. Identification of such clusters in this heterogeneous at-risk group can extend insight into the presence and severity of children’s co-occurring problems and guide intervention and prevention efforts. Latent class analysis (LCA) was used to detect clusters among 308 childhood arrestees (mean age 10.7 years), based on dichotomous dynamic correlates of offending present at the time of first arrest. Correlates in the individual, peer and family domains were assessed at baseline and 2-year follow-up, using standardized instruments. This resulted in identification of a low problem group characterized by few problems across all domains (40.2 %), an externalizing intermediate problem group characterized by mainly externalizing problems on the individual and peer domains (39.4 %), and a pervasive high problem group characterized by numerous problems across all domains (20.4 %). Cluster membership was most stable for the low problem group (71.4 %), followed by the externalizing intermediate problem group (49.5 %). Transition was highest in the pervasive high problem group (63.0 %), with the majority of children progressing to the externalizing intermediate problem group. The identification of such distinct clusters among childhood arrestees, differing in the presence of co-occurring problems, stresses the importance of a first police arrest as an opportunity for early recognition of children in need of care. As problems present at the time of first arrest do not persist in every child, careful periodic monitoring is needed.     

Implicit meaning in 18‐month‐old toddlers

A substantial body of evidence demonstrates that infants understand the meaning of spoken words from as early as 6 months. Yet little is known about their ability to do so in the absence of any visual referent, which would offer diagnostic evidence for an adult‐like, symbolic interpretation of words and their use in language mediated thought. We used the head‐turn preference procedure to examine whether infants can generate implicit meanings from word forms alone as early as 18 months of age, and whether they are sensitive to meaningful relationships between words. In one condition, toddlers were presented with lists of words taken from the same taxonomic category (e.g. animals or body parts). In a second condition, words taken from two other categories (e.g. clothes and food items) were interleaved within the same list. Listening times were found to be longer in the related‐category condition than in the mixed‐category condition, suggesting that infants extract the meaning of spoken words and are sensitive to the semantic relatedness between these words. Our results show that infants have begun to construct the rudiments of a semantic system based on taxonomic relations even before they enter a period of accelerated vocabulary growth.     

Victim Gender,Number of Perpetrators,and Interpersonal Interaction in Stranger Rape: An Analysis of Direct and Moderator Effects

This study examined the direct and moderator effects of number of perpetrators and gender of victim on interpersonal behaviour in stranger rape. Crime scene behaviours representative of hostility, involvement, control, and offender penetration in rape were examined for 496 UK, police‐recorded cases of stranger rape. Cases were grouped according to victim gender (male or female) and number of perpetrators (lone or multiple). This resulted in four groups (lone female, lone male, multiple female, and multiple male) with 124 cases in each. Binary logistic regression and one‐way analysis of variance were used to investigate the relationships between the two predictor variables and 11 criterion variables. Significant direct effects of number of perpetrators were found whereby multiple perpetrator offences were more likely to involve violence and less likely to involve involvement interactions than lone perpetrator offences. Significant direct effects of victim gender were also found whereby male victims were more likely than female victims to experience hostile interactions and be threatened with a weapon and were less likely to experience offender penetration and involvement interactions. Significant crossover interactions were also found for four hostility variables. The utility of the findings are discussed in relation to crime prevention, victim support, and offender intervention.

Three Clinical Experiences with SNP Array Results Consistent with Parental Incest: A Narrative with Lessons Learned

Single nucleotide polymorphism microarrays have the ability to reveal parental consanguinity which may or may not be known to healthcare providers. Consanguinity can have significant implications for the health of patients and for individual and family psychosocial well-being. These results often present ethical and legal dilemmas that can have important ramifications. Unexpected consanguinity can be confounding to healthcare professionals who may be unprepared to handle these results or to communicate them to families or other appropriate representatives. There are few published accounts of experiences with consanguinity and SNP arrays. In this paper we discuss three cases where molecular evidence of parental incest was identified by SNP microarray. We hope to further highlight consanguinity as a potential incidental finding, how the cases were handled by the clinical team, and what resources were found to be most helpful. This paper aims to contribute further to professional discourse on incidental findings with genomic technology and how they were addressed clinically. These experiences may provide some guidance on how others can prepare for these findings and help improve practice. As genetic and genomic testing is utilized more by non-genetics providers, we also hope to inform about the importance of engaging with geneticists and genetic counselors when addressing these findings.     

Predicting Bystander Behavior to Prevent Sexual Assault on College Campuses: The Role of Self-Efficacy and Intent

Bystander intervention has been increasingly applied to prevent sexual violence on college campuses. Its underlying theory assumes unidirectional relationships between variables, predicting that bystander behaviors (i.e., actions taken to intervene in sexual violence situations) will be influenced by bystander intentions (BI; i.e., likelihood to intervene in the future), which in turn will be affected by bystander efficacy (BE; i.e., confidence to intervene). One question for theory is whether a reciprocal relationship exists between BI and BE. We used structural equation modeling (SEM) with longitudinal data to test unidirectional and reciprocal causal relations between BI and BE. Participants (n = 1390) were students at a northeastern US university. Four models were examined using SEM: (1) a baseline model with autoregressive paths; (2) a model with autoregressive effects and BI predicting future BE; (3) a model with autoregressive effects and BE predicting future BI; and, (4) a fully cross‐lagged model. Results indicated that reciprocal causality was found to occur between BI and BE. In addition, a final model demonstrated indirect effects of a bystander intervention program on bystander behaviors through both BI and BE at different time points. Implications for theory and practice are described, and directions for future research discussed.     

Learning Disabilities and Delinquent Behaviors among Adolescents: A Comparison of Those with and without Comorbidity

Research is inconclusive on whether adolescents with learning disabilities (LD) engage in more delinquency than adolescents without such deficits. Mixed results may result from a failure to account for the effects of co-occurring disabilities. Using the National Longitudinal Study of Adolescent Health, this study examines delinquency among adolescents without disabilities to youth with LD, Attention Disorder Symptoms (ADS), and comorbid LD/ADS. Results indicate no significant differences in property offenses, or alcohol, tobacco, and marijuana use; however, youth with LD reported significantly more violence than non-disabled youth. Findings illustrate the heterogeneous effects various disabilities have on delinquent behavior. Future research and policy implications will be discussed.     

Lunch Buddy Mentoring for Children Victimized by Peers: Two Pilot Studies

The authors describe two pilot studies examining the potential benefits of Lunch Buddy (LB) mentoring, a manualized approach to school-based mentoring. LB mentoring takes place during the school lunch period and is designed to promote positive changes in children's peer relationships. In both studies, changes in peer victimization were assessed after one and three semesters of LB mentoring. In the first study, LB mentors were paired with elementary school children (N = 24) identified by child and teacher reports as victimized by peers. Results revealed significant declines in self- and teacher-rated victimization after one and three semesters of mentoring. In the second study, LB mentors were paired with victimized children who also engaged in bullying behavior (N = 23). Results indicated significant declines in self- and teacher-ratings of peer victimization after three semesters of mentoring. In both studies, ratings of perceived harm were low and ratings of satisfaction were high. Discussed are the implications of these findings for future research and for efforts to develop a nonharmful way to help children who are repeatedly victimized.
