Examining Perceptions About Mental Health Care and Help-Seeking Among Rural African American Families of Adolescents

Rural African American children living in poverty have a higher prevalence rate of mental health disorders than their urban counterparts. While access to mental health services is lacking in resource scarce rural communities, African American rural residents may also be the most likely to confront significant barriers to care and help-seeking. Studies of mental health help-seeking behavior among rural families are rare, even rarer are studies of African Americans living in these areas. To address this gap, the current study examined perceptions about help-seeking for adolescents with mental health problems among rural African American families. Data were obtained from African American mothers in rural Georgia to assess their perceptions of the mental health service system, help-seeking processes, and service experiences. A mixed-method approach was implemented, integrating a quantitative survey (n = 163) with qualitative interviews (subsample n = 21). Most of the mothers expressed confidence in mental health care providers’ to help. Preferred sources of support, however, were family, church, and schools. Community stigma towards children with mental health problems and their families was a frequently endorsed perceived barrier to help-seeking. Although cultural mistrust was one of the two most frequently endorsed barriers in the survey, it did not emerge as a universal barrier to help-seeking for the mothers in this sample. Implications for research, policy, and practice include addressing family concerns about stigma, preferences for informal support and non-specialty services in addressing adolescents’ mental health problems, and building community resources to enable all youth to participate in community life.     

Unwanted sex among young adults in the United States: the role of physical disability and cognitive performance

This study examined associations between unwanted sexual experiences and both physical disability and cognitive performance in a nationally representative sample of young adults. We used data from 11,878 participants (ages 26-32) in Waves I, III, and IV of the National Longitudinal Study of Adolescent Health (Add Health). Logistic regressions determined associations between physical disability and level of cognitive performance (using a modified Peabody Picture Vocabulary Test) and the odds of experiencing physically forced and nonphysically coerced sex. Approximately 24% of females and 4% of males reported unwanted sexual experiences. Compared to respondents without disabilities, females with a physical disability had greater odds of experiencing forced sex (OR = 1.49; 95% CI [1.06, 2.08]), whereas males with a physical disability had greater odds of coerced sex (OR = 1.90; 95% CI [1.02, 3.52]). Compared to those with average cognitive performance scores, females with scores above 110 had slightly higher odds of coerced sex (OR = 1.20; 95% CI [1.03-1.41]). Further research on pathways underlying these associations is needed to inform prevention efforts.     

Looking to the future: Prospective economic voting in 2008 Presidential Elections

Despite the economic turmoil of the time, a typical study of vote choice in the 2008 US Presidential Election would (falsely) find little evidence that voters’ opinions about the future state of the economy affected their vote choice. We argue that this misleading conclusion results from serious measurement error in the standard prospective economic evaluations survey question. Relying instead on a revised question, included for the first time in the 2008 American National Election Study, we find that most respondents condition their prospective economic evaluations on potential election outcomes, and that these evaluations are an important determinant of vote choice. A replication in a very different political context – the 2008 Ghanaian election – yields similar results.     

Consideration of the probative value of single donor 15-plex STR profiles in UK populations and its presentation in UK courts

The adoption of new 15 locus STR multiplex systems into UK forensic science would be facilitated by agreed guidelines for reporting the strength of DNA evidence using likelihood ratios. To facilitate such an agreement, we present an analysis of previously published UK allele frequencies for white Caucasian, Afro-Caribbean and Indo-Pakistani populations and investigate their effect on likelihood ratios for single donor profiles. We consider the implication of the five additional loci and suggest a procedure for reporting likelihood ratios for 15-plex STR profiles.     

Developmental validation of the PowerPlex ESX 16 and PowerPlex ESX 17 Systems

We describe the developmental validation study performed on the PowerPlex^® ESX 16 (European Standard Extended 16) and the PowerPlex^® ESX 17 Systems, part of a suite of four new DNA profiling kits developed by Promega in response to the ENFSI and EDNAP groups’ call for new STR multiplexes for Europe. The PowerPlex^® ESX 16 System combines the 11 loci compatible with the UK National DNA Database, contained within the AmpFlSTR^® SGM Plus^® PCR Amplification Kit, with five additional loci: D2S441, D10S1248, D22S1045, D1S1656 and D12S391. The multiplex was designed to incorporate these five new loci as mini- and midi-STRs while maintaining the loci found in the AmpFlSTR^® SGM Plus^® kit as standard size. The PowerPlex^® ESX 17 System amplifies the same loci as the PowerPlex^® ESX 16 System, but with the addition of a primer pair for the SE33 locus. Tests were designed to address the developmental validation guidelines issued by the Scientific Working Group on DNA Analysis Methods (SWGDAM), and those of the DNA Advisory Board (DAB). Samples processed include DNA mixtures, PCR reactions spiked with inhibitors, a sensitivity series, and 306 United Kingdom donor samples to determine concordance with data generated with the AmpFlSTR^® SGM Plus^® kit. Allele frequencies from 242 white Caucasian samples collected in the United Kingdom are also presented. The PowerPlex^® ESX 16 and ESX 17 Systems are robust and sensitive tools, suitable for the analysis of forensic DNA samples. Full profiles were routinely observed with 62.5 pg of a fully heterozygous single source DNA template. In mixture analysis, a range of 52-95% of unique minor contributor alleles was observed at 19:1 mixture ratios where only 25 pg of the minor component was present. Improved sensitivity combined with the robustness afforded by smaller amplicons has substantially improved the quantity of information obtained from degraded samples, and the improved chemistry confers exceptional tolerance to high levels of laboratory prepared inhibitors.     

Toward a more comprehensive understanding of violence against impoverished women

Research and knowledge of violence against impoverished women continues to be limited. To achieve a more comprehensive understanding of violence against impoverished women and therefore inform prevention and intervention efforts for this population, the authors report on recent (past 6 months) physical, sexual, and psychological violence among 898 women who were randomly sampled from temporary shelter settings (n = 460) and low-income housing (n = 438) in Los Angeles County. Women experienced notable rates of violence during the past 6 months (e.g., 23% of sheltered women and 9% of housed women reported physical violence). Perpetrators were diverse, particularly for the sheltered women, including sexual partners, family, and strangers. These findings, and others suggesting that the different types of violence are distinct and severe, may call for more comprehensive screening and intervention efforts to enhance the safety of impoverished women.
