Confronting misconceptions of public housing communities: A qualitative report of community-informed narratives by community members and partners.

Objectives were (a) to understand a community-informed narrative, as told by community members (CMs) and community partners (CPs), about the strengths, experiences, and perspectives of public housing communities; and (b) to analyze similarities and differences between CMs' and CPs' experiences and perspectives. Qualitative interviews were conducted with 22 CMs of public housing (ages 26-58, 100% female caregivers, 96% Black, 4% multiethnic) and 43 CPs (ages 28-78, 67.4% female, 81.4% Black and African American). Four themes were derived from the CM and CP interviews: (1) counters to public narratives, (2) disinvestment begets disinvestment, (3) community conditions should be better, and (4) community cohesion and connection. Findings from this study present community-centered narratives and experiences that were counter to stereotyped public narratives and could influence public perceptions and behavior to inform policy changes related to improving living conditions and supporting CMs in public and low-income housing communities.

Identifying Protective Factors That Mitigate Relations Between Experiences with Violence and Gun Carriage for Black Young Adults Living in Economically Marginalized Urban Communities.

Gun violence disproportionately impacts Black young adults living in economically marginalized urban communities and results in increased risk for injury and death. This study identifies protective factors across the ecological model for Black young adults experiencing peer-based physical and relational aggression and victimization that can mitigate the likelihood of gun carriage. The sample included 141 Black young adults living in economically marginalized communities who had experienced violence. Regression and moderation analyses indicated (1) peer-based physical and relational aggression and victimization negatively associated with gun carriage, and (2) personal assets, positive outlook, student status, and neighborhood attachment interacted with peer-based violent experiences and had protective associations with gun carriage. Findings from this study indicate a need for tailored prevention, policy efforts in order to support Black young adults and decrease gun carriage.

Classification of porcine reproductive and respiratory syndrome virus in Ontario using Bayesian phylogenetics and assessment of temporal trends.

Porcine reproductive and respiratory syndrome virus (PRRSV) is one of the most important swine viruses globally, including in Ontario, Canada. Understanding the evolution and relation of the various PRRSV genotypes in Ontario can provide insight into the epidemiology of the virus. The objectives of this study were to i) describe the variability of PRRSV genotypes in Ontario swine herds, and ii) evaluate possible groupings based on PRRSV genomic data. Virus open reading frame 5 (ORF-5) sequences collected from 2010 to 2018 were obtained from the Animal Health Laboratory, University of Guelph and Bayesian phylogenetic models were created from these. The PRRSV population of Ontario was then categorized into 10 distinct clades. Model comparisons indicated that the model with a constant population assumption fit the data best, which suggests that the net change in the PRRS virus variation of the entire population over the last decade was low. Nonetheless, viruses grouped into individual clades showed temporal clustering during distinct time intervals of the entire study period (P < 0.01).

Le virus du syndrome reproducteur et respiratoire porcin (VSRRP) est l'un des virus porcins les plus importants au monde, y compris en Ontario, au Canada. Comprendre l'évolution et la relation des divers génotypes du VSRRP en Ontario peut donner un aperçu de l'épidémiologie du virus. Les objectifs de cette étude étaient de i) décrire la variabilité des génotypes du VSRRP dans les troupeaux de porcs de l'Ontario et ii) évaluer les regroupements possibles en fonction des données génomiques du VSRRP. Les séquences du cadre de lecture ouvert 5 du virus (ORF-5) recueillis de 2010 à 2018 ont été obtenues auprès du Laboratoire de santé animale de l'Université de Guelph et des modèles phylogénétiques bayésiens ont été créés à partir de ceux-ci. La population de VSRRP de l'Ontario a ensuite été classée en 10 clades distincts. Les comparaisons de modèles ont indiqué que le modèle avec une hypothèse de population constante correspondait le mieux aux données, ce qui suggère que le changement net de la variation du virus SRRP de l'ensemble de la population au cours de la dernière décennie était faible. Néanmoins, les virus regroupés en clades individuels ont montré un regroupement temporel à des intervalles de temps distincts de toute la période d'étude (P < 0,01).(Traduit par Docteur Serge Messier).

Assessment of In-Person and Cyber Aggression and Victimization, Substance Use, and Delinquent Behavior During Early Adolescence.

This study evaluated the Problem Behavior Frequency Scale-Adolescent Report (PBFS-AR), a measure designed to assess adolescents' frequency of victimization, aggression, substance use, and delinquent behavior. Participants were 1,263 students (50% female; 78% African American, 18% Latino) from three urban middle schools in the United States. Confirmatory factor analyses of competing models of the structure of the PBFS-AR supported a model that differentiated among three forms of aggression (in-person physical, in-person relational, and cyber), two forms of victimization (in-person and cyber), substance use, and delinquent behavior. This seven-factor model fit the data well and demonstrated strong measurement invariance across groups that differed on sex and grade. Support was found for concurrent validity of the PBFS-AR based on its pattern of relations with school office discipline referrals.

Research trends in farmers' mental health: A scoping review of mental health outcomes and interventions among farming populations worldwide.

BACKGROUND: Mental health issues among farmers are identified population health concerns. While one systematic review focused on suicide in farming populations in the United States, there have been no scoping studies examining mental health in farming communities worldwide. The objectives of this scoping review were to: provide a descriptive analysis of the literature pertaining to mental health outcomes in farming populations; describe the international scope of the research; and highlight published mental health services and interventions that have been evaluated. METHODS: Following Arksey and O'Malley's scoping review framework, five major health and science platforms were used to identify studies examining mental health outcomes in farming populations, worldwide. Studies that met a priori inclusion criteria that were published prior to December 31, 2017 were included in this review. Data synthesis and descriptive statistics were conducted using STATA 15® software; proportions were calculated by country. RESULTS: The initial literature search yielded 9,906 records. After title and abstract screening, 676 articles were reviewed in-full. Of these, 341 met a priori inclusion criteria. Studies included were conducted between 1979 and 2017; the majority (265; 77.7%) were published between 2002-2017. The most frequently measured outcomes were stress (41.9%), suicide (33.1%), and depression (32.6%). Over 70% of studies that examined stress described using quantitative research methods, most predominantly, cross-sectional designs (42.7%). Approximately 64% of studies that measured suicide reported using a quantitative approach; the largest proportion of included suicide studies (33.6%) described using cohort designs. Approximately 84% of studies that measured depression described using quantitative approaches; sixty percent of these studies reported using a cross-sectional study design. Twenty included studies described a mental health service or intervention (5.9%). CONCLUSIONS: This scoping review provides a critical overview of the literature examining mental health outcomes in farming populations worldwide. Given the importance of farming and agriculture, this review can be used to ensure future research complements existing work, avoids unnecessary overlap, and begins to tackle the less-studied mental health outcomes amongst farmers. These results can guide researchers to identified gaps in research and services, leading to a more informed approach to future work, and ultimately, a more comprehensive understanding of mental health among farmers worldwide.

Assessment of adolescents' victimization, aggression, and problem behaviors: Evaluation of the Problem Behavior Frequency Scale.

This study evaluated the Problem Behavior Frequency Scale (PBFS), a self-report measure designed to assess adolescents' frequency of victimization, aggression, and other problem behaviors. Analyses were conducted on a sample of 5,532 adolescents from 37 schools at 4 sites. About half (49%) of participants were male; 48% self-identified as Black non-Hispanic; 21% as Hispanic, 18% as White non-Hispanic. Adolescents completed the PBFS and measures of beliefs and values related to aggression, and delinquent peer associations at the start of the 6th grade and over 2 years later. Ratings of participants' behavior were also obtained from teachers on the Behavioral Assessment System for Children. Confirmatory factor analyses supported a 7-factor model that differentiated among 3 forms of aggression (physical, verbal, and relational), 2 forms of victimization (overt and relational), drug use, and other delinquent behavior. Support was found for strong measurement invariance across gender, sites, and time. The PBFS factors generally showed the expected pattern of correlations with teacher ratings of adolescents' behavior and self-report measures of relevant constructs. (PsycINFO Database Record

Patterns of adolescents' beliefs about fighting and their relation to behavior and risk factors for aggression.

This study examined adolescents' patterns of beliefs about aggression, and how these patterns relate to aggressive and prosocial behavior, and to risk factors associated with aggression. A sample of 477 sixth graders from two urban schools and a school in a nearby county completed measures of beliefs, behavior, and individual, peer and parental factors associated with aggression. Teacher ratings of participants' behavior and emotion regulation were also obtained. The urban sample was 84% African American; the county school was in a rural fringe area with a student population that was 45% Caucasian and 40% African American. Latent class analysis of items on a beliefs measure supported hypotheses predicting three groups: (a) a Beliefs Against Fighting (BAGF) group that opposed the use of aggression (31% of the sample); (b) a Fighting is Sometimes Necessary (FSNEC) group that endorsed beliefs that fighting is sometimes necessary or inevitable (41%), and (c) a Beliefs Supporting Fighting (BSUPF) group that supported aggression across multiple contexts (28%). Differences across groups were found on race/ethnicity and family structure, but not on gender. Significant differences were also found such that the FSNEC group fell between levels of the BAGF and BSUPF groups on most measures. In contrast, the FSNEC and BAGF groups both differed from the BSUPF group, but not from each other on measures of empathy, perceived effectiveness of nonviolence and aggression, and parental messages supporting nonviolence. These differences suggest the need for tailoring prevention approaches for subgroups of adolescents who differ in their patterns of beliefs.
