Purpose.To use Ecological Momentary Assessment with mobile phones to describe where and with whom children's leisure-time physical activity occurs.Design.Repeated assessments across 4 days (Friday–Monday) during nonschool time (20 total).Setting.Chino, California, and surrounding communities.Subjects.Primarily low to middle income children (N = 121; aged 9–13 years; x̄ = 11.0 years, SD = 1.2 years; 52% male, 38% Hispanic/Latino).Measures.Electronic surveys measured current activity (e.g., active play/sports/exercise, watching TV/movies), social company (e.g., family, friends, alone), physical location (e.g., home, outdoors, school), and other perceived contextual features (e.g., safety, traffic, vegetation, distance from home).Analysis.Multilevel linear and multinomial logistic regression.Results.Most of children's physical activity occurred outdoors (away from home) (42%), followed by at home (indoors) (30%), front/backyard (at home) (8%), someone else's house (8%), at a gym/recreation center (3%), and other locations (9%). Children's physical activity took place most often with multiple categories of people together (e.g., friends and family) (39%), followed by family members only (32%), alone (15%), and with friends only (13%). Age, weight status, income, and racial/ethnic differences in physical activity contexts were observed.Conclusions.The most frequently reported contexts for children's leisure time physical activity were outdoors and with family members and friends together.

We present a case study that utilizes community-based participatory research principles, community-organizing, and evaluation processes as an example of how to conduct community-based research to maximize compliance with policy implementation on tobacco sales in the retail environment. The study covers five different vulnerable communities in Los Angeles, California, including socioeconomically disadvantaged African American, American Indian, Hispanic Americans, Korean, and non-Hispanic Whites. We document barriers to compliance with the U.S. Food and Drug Administration, a government authority in charge of implementing tobacco policy. The case study presents a step-by-step community-based participatory research process with community-organizing principles to help guide the conduct of similar types of research. We discuss development and implementation of culturally tailored and language-specific research protocols. We provide examples of instrumentation development and make a case for community-based research on tobacco control in vulnerable populations. Our research design utilizes a mixed-methods approach, including qualitative (focus groups with key opinion leaders) and quantitative methods via retailer surveys and store audits/observations. We highlight lessons learned and benefits of community inclusion in conducting this type of research.

Evidence-based preventive interventions developed over the past two decades represent great potential for enhancing public health and well-being. Research confirming the limited extent to which these interventions have been broadly and effectively implemented, however, indicates much progress is needed to achieve population-level impact. In part, progress requires Type 2 translation research that investigates the complex processes and systems through which evidence-based interventions are adopted, implemented, and sustained on a large scale, with a strong orientation toward devising empirically-driven strategies for increasing their population impact. In this article, we address two core challenges to the advancement of T2 translation research: (1) building infrastructure and capacity to support systems-oriented scaling up of evidence-based interventions, with well-integrated practice-oriented T2 research, and (2) developing an agenda and improving research methods for advancing T2 translation science. We also summarize a heuristic "Translation Science to Population Impact (TSci Impact) Framework." It articulates key considerations in addressing the core challenges, with three components that represent: (1) four phases of translation functions to be investigated (pre-adoption, adoption, implementation, and sustainability); (2) the multiple contexts in which translation occurs, ranging from community to national levels; and (3) necessary practice and research infrastructure supports. Discussion of the framework addresses the critical roles of practitioner–scientist partnerships and networks, governmental agencies and policies at all levels, plus financing partnerships and structures, all required for both infrastructure development and advances in the science. The article concludes with two sets of recommended action steps that could provide impetus for advancing the next generation of T2 translation science and, in turn, potentially enhance the health and well-being of subsequent generations of youth and ...

This study evaluated the relationship between level of program implementation and change in adolescent drug use behavior in the Midwestern Prevention Project (MPP), a school- and community-based program for drug abuse prevention. Trained teachers implemented the pro gram with transition year students. Implementation was measured by teacher self-report and validated by research staff reports. Adolescent drug use was measured by student self-report; an expired air measure of smoking was used to increase the accuracy of self-reported drug use. Regression analyses were used to evaluate adherence; exposure, or amount of implementation; and reinvention. Results showed that all schools assigned to the program condition adhered to the research by implementing the program. Exposure had a significant effect on minimizing the increase in drug use from baseline to one year. Exposure also had a larger magnitude of intervention effect than experimental group assignment. Reinvention did not affect drug use. Results are discussed in terms of research assumptions about quality of program implementation, and possible school-level predictors of implementation.

OBJECTIVE: Blacks/African Americans have experienced direct public health harm from US governmental agencies (eg, police violence, Tuskegee syphilis experiment) that may influence perceptions of the trustworthiness of government messages regarding tobacco products. Consequently, we sought to explore Black Americans' awareness of and trust in the FDA's role as a tobacco regulator. METHODS: Data were from 2 focus groups conducted with a purposive sample of 23 Black stakeholders in Los Angeles, California. Discussions were audio-recorded and transcribed verbatim for analysis. RESULTS: Although most (N = 14; 61%) participants were aware of the FDA's role as a tobacco regulator, they all noted that the Black community in Los Angeles is not aware. Recurrent across the focus groups were discussions about distrust in the FDA with 4 main contributing factors: (1) that the FDA is influenced by the tobacco, agricultural, and pharmaceutical industries; (2) that the FDA is influenced by money and politics; (3) that the FDA is a bureaucracy exercising monopoly and power; and (4) that the FDA lacks technical capacity and competence to regulate tobacco products. CONCLUSIONS: Study findings highlight opportunities for the FDA to increase awareness and build trust in their tobacco regulatory role through communication campaigns targeted at Black Americans, and community engagement with Black stakeholders.

Little documentation exists regarding the functioning of formalized adolescent groups as drug abuse prevention agents. Two studies are described that were conducted at high schools whose students are at high risk for drug abuse. Twenty-one schools were randomly assigned to one of three conditions: (a) standard care, (b) classroom drug abuse education only, or (c) classroom plus school-as-conununity. Results of the first study tndicated that the school-as-communtty component—which involved weekly meetings and periodic events at seven schools—was imple mented as planned, drug abused focused, and perceived as productive in discouraging drug abuse. In the second study, staff in the classroom plus school-as-community condition self- reported involvement in the greatest number of community activities across the school year, compared with staff from the other two conditions. These two studies support the feasibility of formalized groups of high-risk youth to promote drug-free events.

OBJECTIVES: Research is limited on tobacco retailers' perceptions of the Food and Drug Administration's (FDA) tobacco regulatory authority overall, and less exists related to retailers in predominantly African-American or other racial/ethnic neighborhoods. We assessed differences in perceptions of the FDA's tobacco regulatory authority and barriers to compliance among retailers in African-American and non-African-American neighborhoods in Los Angeles, California. METHODS: Overall, 700 tobacco retailer interviews assessed demographic characteristics and perceptions of the FDA. RESULTS: Retailers in African-American neighborhoods self-identified as Hispanic/Latino (43.9% vs 39.6% non-African-American), African-American (21.2% vs 2.6% non-African-American) or Asian (19.7% vs 19.5% non-African-American). Retailers in African-American neighborhoods were significantly less likely to perceive the FDA as a trustworthy source (p = .03; vs non-African-American), but more likely to report that they do not know the federal rules (p = .002), do not understand the federal rules (p = .004), and that tobacco companies encourage them not to follow the federal rules (p = .04). CONCLUSIONS: Tobacco control agencies can use this information about retailer perceptions to design education/training materials in order to increase trust, mitigate barriers, and enhance compliance.
