OBJECTIVES. The purpose of this study was to identify circumstances in which biochemical assessments of smoking produce systematically higher or lower estimates of smoking than self-reports. A secondary aim was to evaluate different statistical approaches to analyzing variation in validity estimates. METHODS. Literature searches and personal inquiries identified 26 published reports containing 51 comparisons between self-reported behavior and biochemical measures. The sensitivity and specificity of self-reports of smoking were calculated for each study as measures of accuracy. RESULTS. Sensitivity ranged from 6% to 100% (mean = 87.5%), and specificity ranged from 33% to 100% (mean = 89.2%). Interviewer-administered questionnaires, observational studies, reports by adults, and biochemical validation with cotinine plasma were associated with higher estimates of sensitivity and specificity. CONCLUSIONS. Self-reports of smoking are accurate in most studies. To improve accuracy, biochemical assessment, preferably with cotinine plasma, should be considered in intervention studies and student populations.

Seattle Partners for Healthy Communities (SPHC) is a multidisciplinary collaboration of community agencies, community activists, public health professionals, academics, and health providers who conduct research aimed at improving the health of urban, socioeconomically marginalized Seattle communities. SPHC uses a community-based participatory research approach to address social factors that affect the health of these communities. This article describes three SPHC projects that focus on social determinants of health, particularly the development of social support and improving housing quality. The characteristics of community participation in each of these projects are discussed and show a spectrum of participation. Although projects successfully addressed proximal social factors affecting health, influencing more distal underlying factors was more difficult. Implications for researchers using a community-based participatory research approach and public health practitioners seeking to engage communities in addressing social determinants of health are presented.

Improving community health "from the ground up" entails a comprehensive ecological approach, deep involvement of community-based entities, and addressing social determinants of population health status. Although the Centers for Disease Control and Prevention, the Office of the Surgeon General, and other authorities have called for public health to be an "inter-sector" enterprise, few models have surfaced that feature local health departments as a key part of the collaborative model for effecting community-level change. This paper presents evaluation findings and lessons learned from the Partnership for the Public's Health (PPH), a comprehensive community initiative that featured a central role for local health departments with their community partners. Funded by The California Endowment, PPH provided technical and financial resources to 39 community partnerships in 14 local health department jurisdictions in California to promote community and health department capacity building and community-level policy and systems change designed to produce long-term improvements in population health. The evaluation used multiple data sources to create progress ratings for each partnership in five goal areas related to capacity building, community health improvement programs, and policy and systems change. Overall results were generally positive; in particular, of the 37 partnerships funded continuously throughout the 5 years of the initiative, between 25% and 40% were able to make a high level of progress in each of the Initiative's five goal areas. Factors associated with partnership success were also identified by local evaluators. These results showed that health departments able to work effectively with community groups had strong, committed leaders who used creative financing mechanisms, inclusive planning processes, organizational changes, and open communication to promote collaboration with the communities they served.
