Preliminary Evaluation of the Effectiveness of Perinatal Mindfulness-Based Well-Being and Parenting Programs for Low-Income New Mothers.

Objectives: This study examined specificity in the effects of three perinatal mindfulness-based prevention programs that differed in their timing (prenatal, postpartum) and target (maternal well-being, parenting). Effects on maternal mental health (depression, anxiety, resilience), mindfulness, and observed parenting, as well as observed, physiological, and mother-report indicators of infant self-regulation, were examined. Methods: The programs were evaluated in a racially and ethnically diverse sample of first-time mothers (n = 188) living in low-income contexts using intention-to-treat analysis. Mothers were assigned to a prenatal well-being, postpartum well-being, parenting, or book control group. Multi-method assessments that included questionnaire, observational, and physiological measures were conducted at four time points: during pregnancy (T1) and when infants were 2-4 months (T2), 4-6 months (T3), and 10-12 months. Results: Compared to the postpartum intervention and control groups, the 6-week prenatal well-being intervention was related to decreases in depressive symptoms during pregnancy but not postpartum, higher maternal baseline respiratory sinus arrhythmia (RSA), fewer intrusive control behaviors, and lower infant cortisol levels in the early postpartum period. Compared to all other groups, the postpartum parenting intervention was related to decreases in maternal anxiety and increases in responsive parenting. Some differential effects across programs might be due to differences in attendance rates in the prenatal (62%) vs. postpartum (35%) groups. Conclusions: The findings suggest that brief mindfulness-based well-being and parenting preventive interventions can promote maternal and infant mental health in families living in low-income, high-stress settings, particularly if accessibility can be enhanced. Preregistration: This study is not preregistered.

Pre-COVID-19 predictors of low-income women's COVID-19 appraisal, coping, and changes in mental health during the pandemic.

Study examined predictors and mental health consequences of appraisal (threat, support satisfaction) and coping (active, avoidant) in a sample of low-income women during coronavirus disease 2019 (COVID-19). Pre-COVID-19 contextual risk and individual resources and COVID-19-specific risk factors were examined as predictors of COVID-19 appraisal and coping, which, in turn, were tested as predictors of changes in depression and anxiety across the pandemic. Pre-COVID-19 resilience predicted more active coping, whereas pre-COVID-19 anxiety and depression predicted more avoidant coping and lower support satisfaction, respectively. Increases in anxiety were predicted by lower pre-COVID-19 self-compassion and higher concurrent threat appraisal and avoidant coping. Increases in depression were related to lower pre-COVID-19 self-compassion, active coping and support satisfaction, and higher COVID-19 hardships and health risk. Findings highlight contextual and individual factors and processes that contribute to mental health problems in a vulnerable population during community-level stressors, with implications for prevention and intervention.

Maternal Mental Health and Child Adjustment Problems in Response to the COVID-19 Pandemic in Families Experiencing Economic Disadvantage.

Parents living in low-income contexts shouldered disproportionate hardships during the COVID-19 pandemic with consequences to maternal mental health and child adjustment. The current study uses a sample of first-time mothers (N = 147) of young toddlers, all living in low-income contexts, to examine the roles of pre-pandemic and COVID-19-specific risk and individual resilience factors in the prediction of changes to maternal mental health coinciding with the onset of the pandemic. Maternal mental health symptoms, in turn, were examined as predictors of child adjustment problems across 6 months of the pandemic and as a potential mechanism conferring pandemic risks to children. While pre-pandemic cumulative contextual risk (i.e., low income, single parent status, adolescent parent status, financial instability) did not predict changes in maternal mental health from prior to during the pandemic, COVID-19-specific health risks predicted changes in maternal mental health from before the pandemic, as well as across 6 months of the pandemic. Regarding individual resilience factors to changes in maternal mental health, pre-pandemic self-compassion predicted better maternal mental health during the pandemic, as did COVID-19-specific appraisal and coping strategies. In turn, maternal mental health predicted children's early pandemic levels of adjustment problems and changes in adjustment problems across 6 months of the pandemic, with maternal mental health serving an indirect pathway of COVID-19-specific health risks to children's adjustment. The findings highlight pathways of risk and resilience during a global health crisis and point to targets for interventions in community level crises to promote maternal and child mental health.

A pilot feasibility study of mindfulness childbirth education for women with a history of sexual trauma.

BACKGROUND: and purpose: Pregnant women with a history of sexual trauma are at increased risk for mood disorders. Mindfulness interventions delivered prenatally may reduce risk of mood disorders. The purpose of this pilot was to examine the feasibility and acceptability of Mindfulness-Based Childbirth and Parenting (MBCP) for women with a history of sexual trauma. MATERIALS AND METHODS: A one-group repeated measures design was employed, involving three assessments: baseline, post-intervention and at eight weeks postpartum. Twelve pregnant women were recruited and enrolled. Self-report measures and open-ended written questionnaires were used to assess health outcomes and intervention acceptability. RESULTS: Results show high satisfaction with the program, an immediate reduction in prenatal anxiety, and longitudinal increase in interoceptive awareness skills. CONCLUSION: The results suggest the feasibility and acceptability of the MBCP approach for women with a history of sexual trauma.

Participant Engagement in and Perspectives on a Web-Based Mindfulness Intervention for 9-1-1 Telecommunicators: Multimethod Study.

BACKGROUND: Demanding working conditions and secondary exposure to trauma may contribute to a high burden of stress among 9-1-1 telecommunicators, decreasing their ability to work effectively and efficiently. Web-based mindfulness-based interventions (MBIs) can be effective in reducing stress in similar populations. However, low engagement may limit the effectiveness of the intervention. OBJECTIVE: The aim of this study was to assess participant engagement in a Web-based MBI designed for 9-1-1 telecommunicators. Specifically, we sought to describe the following: (1) participant characteristics associated with intervention engagement, (2) participant perspectives on engaging with the intervention, and (3) perceived challenges and facilitators to engaging. METHODS: We used qualitative and quantitative data from participant surveys (n=149) that were collected to assess the efficacy of the intervention. We conducted descriptive and bivariate analyses to identify associations between demographic, psychosocial, and workplace characteristics and engagement. We conducted a thematic analysis of qualitative survey responses to describe participant experiences with the MBI. RESULTS: We found that no individual participant characteristics were associated with the level of engagement (low vs high number of lessons completed). Participant engagement did vary by the call center (P<.001). We identified the following overarching qualitative themes: (1) the participants perceived benefits of mindfulness practice, (2) the participants perceived challenges to engage with mindfulness and the intervention, and (3) intervention components that facilitated engagement. The participants expressed positive beliefs in the perceived benefits of practicing mindfulness, including increased self-efficacy in coping with stressors and increased empathy with callers. The most commonly cited barriers were work-related, particularly not having time to participate in the intervention at work. Facilitators included shorter meditation practices and the availability of multiple formats and types of intervention content. CONCLUSIONS: The findings of this study suggest that efforts to improve intervention engagement should focus on organizational-level factors rather than individual participant characteristics. Future research should explore the effect of mindfulness practice on the efficiency and effectiveness of 9-1-1 telecommunicators at work.

Destress 9-1-1-an online mindfulness-based intervention in reducing stress among emergency medical dispatchers: a randomised controlled trial.

OBJECTIVES: Emergency medical dispatchers (EMDs) experience significant stress in the workplace. Yet, interventions aimed at reducing work-related stress are difficult to implement due to the logistic challenges associated with the relatively unique EMD work environment. This investigation tested the efficacy of a 7-week online mindfulness-based intervention (MBI) tailored to the EMD workforce. METHODS: Active-duty EMDs from the USA and Canada (n=323) were randomly assigned to an intervention or wait list control condition. Participants completed surveys of stress and mindfulness at baseline, post intervention, and 3 months follow-up. Repeated measures mixed effects models were used to assess changes in stress and mindfulness. RESULTS: Differences between the intervention group and control group in pre-post changes in stress using the Calgary Symptoms of Stress Inventory were statistically significant, with a difference of -10.0 (95% CI: -14.9, -5.2, p<0.001) for change from baseline to post intervention, and a difference of -6.5 (95% CI: -11.9, -1.1, p=0.02) for change from baseline to 3 months follow-up. Change in mindfulness scores did not differ between groups. However, increases in mindfulness scores were correlated with greater reductions in stress for all participants, regardless of group (r=-0.53, p<0.001). CONCLUSIONS: Development of tailored online MBIs for employees working in challenging work environments offer a promising direction for prevention and intervention. This study found that a short, weekly online MBI for EMDs resulted in reductions in reports of stress. Implications of online MBIs in other emergency responding populations and directions for future research are discussed.

Protocol: a multi-level intervention program to reduce stress in 9-1-1 telecommunicators.

BACKGROUND: Nationwide, emergency response systems depend on 9-1-1 telecommunicators to prioritize, triage, and dispatch assistance to those in distress. 9-1-1 call center telecommunicators (TCs) are challenged by acute and chronic workplace stressors: tense interactions with citizen callers in crisis; overtime; shift-work; ever-changing technologies; and negative work culture, including co-worker conflict. This workforce is also subject to routine exposures to secondary traumatization while handling calls involving emergency situations and while making time urgent, high stake decisions over the phone. Our study aims to test the effectiveness of a multi-part intervention to reduce stress in 9-1-1 TCs through an online mindfulness training and a toolkit containing workplace stressor reduction resources. METHODS/DESIGN: The study employs a randomized controlled trial design with three data collection points. The multi-part intervention includes an individual-level online mindfulness training and a call center-level organizational stress reduction toolkit. 160 TCs will be recruited from 9-1-1 call centers, complete a baseline survey at enrollment, and are randomly assigned to an intervention or a control group. Intervention group participants will start a 7-week online mindfulness training developed in-house and tailored to 9-1-1 TCs and their call center environment; control participants will be "waitlisted" and start the training after the study period ends. Following the intervention group's completion of the mindfulness training, all participants complete a second survey. Next, the online toolkit with call-center wide stress reduction resources is made available to managers of all participating call centers. After 3 months, a third survey will be completed by all participants. The primary outcome is 9-1-1 TCs' self-reported symptoms of stress at three time points as measured by the C-SOSI (Calgary Symptoms of Stress Inventory). Secondary outcomes will include: perceptions of social work environment (measured by metrics of social support and network conflict); mindfulness; and perceptions of social work environment and mindfulness as mediators of stress reduction. DISCUSSION: This study will evaluate the effectiveness of an online mindfulness training and call center-wide stress reduction toolkit in reducing self-reported stress in 9-1-1 TCs. The results of this study will add to the growing body of research on worksite stress reduction programs.

Impact of new technologies on stress, attrition and well-being in emergency call centers: the NextGeneration 9-1-1 study protocol.

BACKGROUND: Our public health emergency response system relies on the "first of the first responders"-the emergency call center workforce that handles the emergency needs of a public in distress. Call centers across the United States have been preparing for the "Next Generation 9-1-1" initiative, which will allow citizens to place 9-1-1 calls using a variety of digital technologies. The impacts of this initiative on a workforce that is already highly stressed is unknown. There is concern that these technology changes will increase stress, reduce job performance, contribute to maladaptive coping strategies, lower employee retention, or change morale in the workplace. Understanding these impacts to inform approaches for mitigating the health and performance risks associated with new technologies is crucial for ensuring the 911 system fulfills its mission of providing optimal emergency response to the public. METHODS: Our project is an observational, prospective cohort study framed by the first new technology that will be implemented: text-to-911 calling. Emergency center call takers will be recruited nationwide. Data will be collected by online surveys distributed at each center before text-to-911 implementation; within the first month of implementation; and 6 months after implementation. Primary outcome measures are stress as measured by the Calgary Symptoms of Stress Index, use of sick leave, job performance, and job satisfaction. Primary analyses will use mixed effects regression models and mixed effects logistic regression models to estimate the change in outcome variables associated with text-to-911 implementation. Multiple secondary analyses will examine effects of stress on absenteeism; associations between technology attitudes and stress; effects of implementation on attitudes towards technology; and mitigating effects of job demands, job satisfaction, attitudes towards workplace technology and workplace support on change in stress. DISCUSSION: Our public health dependence on this workforce for our security and safety makes it imperative that the impact of technological changes such as text-to-911 are researched so appropriate intervention efforts to can be developed. Failing to protect our 9-1-1 call takers from predictable health risks would be similar to knowingly exposing field emergency responders to a toxic situation without following OSHA required training and practice standards assuring their protection.

Medical interpreters and bilingual school staff: Potential disaster information conduits?

OBJECTIVES: Dissemination of trusted disaster information to limited English proficient (LEP) communities may mitigate the negative effects these higher risk communities experience in disasters. For immigrant communities, disaster messages may be perceived with skepticism, and fear of public officials may affect compliance with disaster messages. This study explores whether medical interpreters (MIs) and bilingual school staff (BSS) are already informal information sources for LEP communities, and could their connection to both public service organizations and LEP communities make them ideal efficient, trusted disaster information conduits for LEP communities. DESIGN: The authors conducted a mixed methods study, which included MI individual interviews, Latino community focus groups, an MI employer survey, and school administrator interviews. SETTING: To ensure diversity in the sample, data were collected in both Los Angeles and Seattle. RESULTS: MIs, MI employers, and schools are willing to communicate disaster information to LEP communities. MIs and BSS are connected to and share information with LEP communities. Latino LEP communities are eager for more disaster information and sources. CONCLUSIONS: The study adds to the evidence that a multipronged approach that includes collaborating with professionals linked to immigrant communities, such as MIs and BSS, could be an effective method of disaster information dissemination. Working with MIs and BSS as part of a wider dissemination strategy would promote a community-based interpersonal flow of information that would contribute to LEP community's trust in the message.

Exploring bi-directional and SMS messaging for communications between Public Health Agencies and their stakeholders: a qualitative study.

BACKGROUND: Communication technologies that enable bi-directional/two-way communications and cell phone texting (SMS) between public health agencies and their stakeholders may improve public health surveillance, ensure targeted distribution of alerts to hard-to-reach populations, reduce mortality and morbidity in an emergency, and enable a crucial feedback loop between public health agencies and the communities they serve. Building on prior work regarding health care provider preferences for receiving one-way public health communications by email, fax or SMS, we conducted a formative, exploratory study to understand how a bi-directional system and the incorporation of SMS in that system might be used as a strategy to send and receive messages between public health agencies and community-based organizations which serve vulnerable populations, health care providers, and public health workers. Our research question: Under what conditions and/or situations might public health agencies utilize bi-directional and/or SMS messaging for disseminating time-sensitive public health information (alerts, advisories, updates, etc.) to their stakeholders? METHODS: A mixed methods (qualitative and quantitative) study was conducted between April and July 2014. Data collection included a survey distributed to health care providers and semi-structured interviews with providers, community- and government-based organization leaders and directors, and public health agency internal workforce staff. Survey respondents and interviewees were asked about their exposure to public health messages, how these messages are received and how the information in these messages are handled, and in what situations (for example, a local vs. a national event, a pandemic or emergency vs. a health update) a bi-directional and/or SMS messaging system might improve communications between public health agencies and their stakeholder group. Interview and survey data were qualitatively analyzed. Thematic codes were quantitized into dichotomous variables of 0 or 1 on a per respondent basis to enumerate the presence or absence of each thematic code, enable quantitative analysis, and inform interpretation of findings. RESULTS: Five major themes emerged from synthesizing survey and interview results: 1) Regardless of situational context (emergency vs. non-urgent) and message recipient (stakeholder group), e-mail is a favored modality for receiving public health messages; 2) The decision to use bi-directional, SMS or multiple communication strategies is complex and public health agencies' need to manage messaging concerns/barriers and benefits for all parties; 3) Both public health agencies and their stakeholders share similar values/uses and concerns regarding two-way public health messaging and SMS; 4) Public health is highly trusted, thus thoughtful, effective messaging will ensure continuation of this goodwill; and 5) Information reciprocity between public health agencies and stakeholders who share their information is essential. CONCLUSIONS: Multiple communication strategies might be utilized but the choice of a specific strategy needs to balance message content (emergency vs. routine communications), delivery (one- vs. two-way), channel (SMS, email, etc.), and public health agency burden with stakeholder preferences and technical capabilities, all while mitigating the risk of message overload and disregard of important communications by recipients.

Emergency communications within the limited English proficient Chinese community.

Limited English speaking communities face communication challenges during emergencies. Our objective was to investigate Chinese limited English proficiency individuals' perceptions of and inclination to interact with emergency communication systems. A telephone survey was conducted in Mandarin or Cantonese with 250 ethnic Chinese individuals who spoke little or no English. Respondents who spoke no English were less likely to name 9-1-1 as their first source of help for a medical emergency than those who spoke some English (p < 0.01). Those reporting higher levels of confidence in handling the situation were more likely to name 9-1-1 as their first source of help, as were those who listed 9-1-1 as their most trusted source of help (p < 0.01). For this group, the results indicate that calling 9-1-1 may require a sense of self-efficacy. Not calling 9-1-1 in a medical emergency can have serious health consequences, thus interventions are needed to increase confidence in accessing 9-1-1.

The effect of language barriers on dispatching EMS response.

OBJECTIVE: The objective of this study was to investigate the effect of language barriers during medical 9-1-1 calls, on the time to dispatch and level of medical aid (Basic or Advanced Life Support). METHODS: All 9-1-1 medical calls to two large call centers during one week for each of the months of August, October, December 2010 and February 2011, were reviewed for a notation of language barrier (LB). Non-language barrier calls were identified from the same time period such that there were an equal proportion of LB and non-LB calls by dispatch code and dispatcher. A total of 272 language barrier calls were identified. The computer-assisted dispatch (CAD) reports for the LB and non-LB calls were abstracted by research staff using a standard form, including: Start time of call, time to dispatch of BLS, time to dispatch of ALS, dispatch code, interpretation service use, on-scene upgrade to ALS, and on-scene downgrade to BLS. 9-1-1 recordings were abstracted for LB calls only to obtain information about use of interpreter services. Difference between LB and English speakers in time to assignment of BLS and ALS was examined using linear mixed effects models with log time as the outcome; language barrier, call center and dispatch code as fixed effects and dispatcher as a random effect. RESULTS: The effect of language barrier on time to BLS assignment was, on average, 33% longer (p < 0.001) and time to ALS assignment 43% longer (P = 0.008). A majority of the effect was due to the effect of interpreter use, which increased time to BLS by 82% and 125% for ALS, when compared to non-language barrier calls. Data from the 9-1-1 recordings showed an average of 49 seconds between connecting to the service operator and connecting to the language interpreter. Language barrier calls were more likely to be up- and down-graded, only statistically significantly so for on-scene downgrades. CONCLUSION: Language barriers increase time to dispatch and the accuracy of the level of aid dispatched during medical emergency calls. Decreasing the time to connecting to an actual interpreter when using an interpretation service could minimize existing delays.

Serving limited English proficient callers: a survey of 9-1-1 police telecommunicators.

INTRODUCTION: The emergency telephone number 9-1-1 serves as a lifeline to the public during emergencies, and first responders rely on information gathered by 9-1-1 telecommunicators who speak with callers. Timely, accurate information from the telecommunicators is essential for providing appropriate care on scene. Language barriers can hamper these efforts and result in less efficient information exchange. Although 9-1-1 telecommunicators may access over-the-phone interpreter (OPI) services to facilitate communication, managing three-way communication during an emergency is challenging. Problem There is little published on the relationship between limited English proficient (LEP) callers and 9-1-1 police telecommunicators, and the role of OPI services during these calls. Further, little is known about effective strategies to manage such calls. METHODS: In King County, Washington, 9-1-1 police telecommunicators were surveyed about their experiences handling LEP calls and managing three-way communication with OPI services. The survey contained 13 multiple-choice and three open-response questions addressing communication strategies, challenges with LEP callers, and three-way communication with OPI services. Goodman-Kruskal Gamma and chi-square tests were conducted with OPI use as the dependent variable. Additional analyses were conducted using stress levels as the dependent variable. RESULTS: Of 123 respondents, 69 (56.5%) 9-1-1 telecommunicators reported utilizing OPI services at least 75% of the time when receiving a call from an LEP caller. Further, 35 (28.7%) of these telecommunicators reported calls with LEP individuals as more stressful than calls with fluent English speakers. Dispatcher stress level during LEP calls compared with stress during calls with fluent English speakers was positively associated with use of OPI services (P < .01). Further, stress level was also positively associated with telecommunicator difficulties in assessing the situation with respect to officer safety (P < .01). Sixty-three (58.3%) of the telecommunicators described difficulties assessing the situation to determine the appropriate response as the biggest challenge with LEP callers. Additionally, 62 (53%) identified knowing their location in English as information LEP callers need to know prior to calling 9-1-1. CONCLUSION: These results highlight intervention opportunities for both 9-1-1 telecommunicators and LEP communities. Together, interventions such as working with LEP communities to educate them on best communication practices during 9-1-1 calls, and with 9-1-1 telecommunicators to help them manage three-way communication and reduce stress associated with concern for officer safety may improve emergency communication during 9-1-1 calls.

The role of self-efficacy in communication and emergency response in Chinese limited english proficiency (LEP) populations.

BACKGROUND: Failure to engage in emergency preparedness, response, and recovery contributes to the differential outcome experienced by limited English proficiency (LEP) populations. Little is known about how psychosocial factors influence LEP individuals' perception of emergency and their process of understanding, collecting, and synthesizing information. The purpose of this exploratory study is to understand how LEP conceptualize an emergency situation to determine when help is needed. METHODS: The authors conducted 4 focus groups with 36 adult Chinese LEP speakers living in Seattle. All discussions were audio-taped, translated, and transcribed. Coded text passages were entered into Atlas.ti for data management and model generation. RESULTS: Perception of an emergency situation affects LEP individual's ability to manage the crisis. Self-efficacy may be an important psychological variable that positively shapes an individual's response to an emergency situation by improving their confidence to handle the crisis and ability to connect to resources. Response to emergency resulting from this series of information gathering, synthesis, and utilization may not always result in a positive outcome. DISCUSSION: Self-efficacy in risk communication messages should be included to engage LEPs in emergency preparedness. Effective communication can increase LEPs' awareness of emergency situations and connecting LEP individuals with existing community resources may enhance LEPs' level of self-efficacy in emergencies.

Barriers and facilitators to using 9-1-1 and emergency medical services in a limited English proficiency Chinese community.

Effective communication during a medical emergency is crucial for an appropriate emergency medical services (EMS) response. This exploratory qualitative study explored intentions to use 9-1-1 in a Chinese speaking community and the barriers and facilitators to accessing EMS. Focus groups with Chinese adults who self-reported limited English proficiency were conducted. An inductive iterative approach was used to categorize and connect themes identified in the discussions. Language difficulties, negative perceptions of EMS, perceived costs of using emergency services, and no previous experience with 9-1-1 were commonly described as barriers to calling EMS during emergencies. Positive past experiences with EMS and encountering an emergency situation perceived as too great to manage alone are common facilitators for calling 9-1-1. Further exploration is necessary to assess barriers to calling 9-1-1 unique to specific communities, test findings, and tailor interventions to improve EMS communication.

Preparedness for cardiac emergencies among Cambodians with limited English proficiency.

In the United Sates, populations with limited English proficiency (LEP) report barriers to seeking emergency care and experience significant health disparities, including being less likely to survive cardiac arrest than whites. Rapid utilization of 9-1-1 to access emergency services and early bystander cardiopulmonary resuscitation (CPR) is crucial for successful resuscitation of out-of-hospital cardiac arrest patients. Little is understood about Asian LEP communities' preparedness for emergencies. In this exploratory survey, we sought to assess intentions to call 9-1-1 in an emergency and knowledge of CPR in the Cambodian LEP community. We conducted an in-person interview with 667 Cambodian adults to assess their intentions to call 9-1-1 and their awareness of and training in bystander CPR. While the majority of participants stated that they would call 9-1-1 in an emergency, almost one-third of the sample would call a friend or family member. Awareness of CPR was very high but training in CPR was lower, especially for women. A higher level of English proficiency and greater proportion of time in the US was a strong predictor of CPR training and intention to call 9-1-1 in an emergency. This suggests that greater efforts need to be made to reach the most linguistically-isolated communities (those with little or no English) with emergency information in Khmer.

Older adults' perceptions of clinical fall prevention programs: a qualitative study.

Objective. To investigate motivational factors and barriers to participating in fall risk assessment and management programs among diverse, low-income, community-dwelling older adults who had experienced a fall. Methods. Face-to-face interviews with 20 elderly who had accepted and 19 who had not accepted an invitation to an assessment by one of two fall prevention programs. Interviews covered healthy aging, core values, attributions/consequences of the fall, and barriers/benefits of fall prevention strategies and programs. Results. Joiners and nonjoiners of fall prevention programs were similar in their experience of loss associated with aging, core values they expressed, and emotional response to falling. One difference was that those who participated endorsed that they "needed" the program, while those who did not participate expressed a lack of need. Conclusions. Interventions targeted at a high-risk group need to address individual beliefs as well as structural and social factors (transportation issues, social networks) to enhance participation.

Detection of TNT and Picric Acid on Surfaces and in Seawater by Using Photoluminescent Polysiloles.

Nitroaromatic explosives can be detected in a simple and rapid method by the quenching of the photoluminescence of fluorescent polysiloles. Quenching is achieved by electron transfer from the conduction band of the polysiloles to electron-poor molecules such as picric acid, nitrobenzene, 2,4-dinitrotoluene (DNT), and 2,4,6-trinitrotoluene (TNT). Dilute polymer solutions can also be employed as a forensic spray-on reagent to visualize TNT or picric acid residues under a UV lamp (see picture of the print of a nitrile-gloved hand that had been in contact with TNT).
