Performance evaluation and optimization of multiplex PCRs for the highly discriminating OSU 10-locus set Y-STRs

In a previous study, a new set of Y-chromosome short tandem repeats, the OSU 10-locus set (MPM1 and MPM2), was shown to have a higher discrimination power when evaluated against the 10 SWGDAM loci on a common population panel. Here, we describe the optimization of the multiplex reactions using dye-labeled primers followed by performance evaluations. The loci exhibited high precision, human male specificity, reliability in different body fluids, high sensitivity, stability, and the ability to amplify nonprobative casework and mixture samples. Stutter for the all of the loci, with the exception of the highly polymorphic locus DYS688, was similar to that observed for autosomal loci. The results of the performance evaluations reinforced the utility of these loci.     

Relationships between Agency-Specific Contact,Victimization Type,and Trust and Confidence in the Police and Courts

While the extant research on trust and confidence in the criminal justice system is broad in scope, its individual studies are more limited, leaving much unknown about these relationships. Building on prior research, the current study investigates the relationships between prior contact, victimization, and seven measures of trust and confidence in the police and courts. This study responds to calls for the relationships between trust and confidence in the criminal justice system, race/ethnicity, prior contact, and victimization to be investigated within a single study. Although rare in prior research, outcomes of trust and confidence in local police and courts are individually investigated within the same sample simultaneously. As a first, the current study also separates prior contact by police, courts, community corrections, and institutional corrections and examines four types of victimization (direct violent, vicarious violent, direct non-violent, vicarious non-violent). The latter allows for an examination of potentially more nuanced relationships between victimization and trust and confidence in the police and in the courts.     

Trauma-Informed Resource Parent Training and the Impact on Knowledge Acquisition,Parenting Self-Efficacy,and Child Behavior Outcomes: A Pilot of the Resource Parent Curriculum Parent Management Training (RPC+)

This pilot study illustrates one state’s development, implementation, and outcomes of a trauma-informed curriculum called the Resource Parent Curriculum + CARE (RPC+). The RPC+ is an intensive co-trained curriculum intended to be trauma-informed and skills-based focused on ameliorating child behavior problems that are frequently the source of parenting stress and placement instability. This article will provide a literature review of child and caregiver needs, describe the training curriculum, and present the results from the pilot implementation of the curriculum. Preliminary findings from this study show participants of the RPC+ show positive changes pre- to post-training on a number of dimensions that have been correlated with placement stability for children including knowledge of trauma, parenting self-efficacy, and child behavior outcomes.     

Parental attitudes following exposure to child abuse prevention campaign materials: a randomized trial

The purpose of this study was to evaluate child abuse prevention campaign materials. Using a randomized posttest design, 600 parents from an online research panel were recruited and surveyed. Multiple regression results indicate that exposure to the campaign materials had a significant relationship with four of the five domains (effects of child maltreatment, the appropriateness of harsh parenting, the physical dangers and needs unique to childhood, and the power to prevent child maltreatment). These results have implications for the child abuse prevention practitioners who seek to design and distribute effective campaign materials.     

A Test of Two Methods of Recall for Violent Events

This project took advantage of an opportunity to test the comparability of two different methods for collecting self-reports of violent incidents. Using a life events calendar (LEC) approach, we collected data from individuals about violent incidents that occurred within a 1–3-year prior time period. These individuals had been research participants in a previous study that collected information about violent incidents using prospective, weekly interviews. Results using the LEC method were compared with the weekly self-reports of violence for an overlapping recall period. This allowed us to see how well the recall of violent incidents at a later date mapped onto reports obtained within seven days of any incidents. Overall results show a significant amount of under-reporting using the life-event calendar methodology compared to the weekly interview approach, but some higher concordance of reporting was found for serious rather than minor violence.     

A friend in need: the role of friendship quality as a protective factor in peer victimization and bullying

This study examined friendship quality as a possible moderator of risk factors in predicting peer victimization and bullying. Children (50 boys and 49 girls, ages 10 to 13 years) reported on the quality of their best friendship, as well as their bullying and victimization tendencies. Parents reported on their child's internalizing and externalizing behaviors, in addition to bullying and victimization tendencies. Results indicated that externalizing problems were related to bullying behavior; however, friendship quality moderated this relation such that among children with externalizing behaviors, a high-quality friendship significantly attenuated bullying behavior. Internalizing problems and low friendship quality were significantly related to victimization; however, friendship quality did not moderate the relation between internalizing problems and victimization. Implications for interventions based on these findings are discussed.
