Public hospital safety net systems face constant financial constraints, hindering their ability to provide adequate healthcare services. Many healthcare reform proposals would further weaken these systems by redirecting current safety net resources toward private insurance. Despite or perhaps because of this challenging environment, many successes in improving care for poor and vulnerable populations have been pioneered in safety net systems. San Francisco, California, is implementing several innovative programs to strengthen the financial viability of its healthcare safety net while also attempting to improve the access to and the quality of healthcare services.

Major behavioral theories focus on proximal influences on behavior that are considered to be predominantly cognitive characteristics of the individual largely uninfluenced by social context. Social ecological models integrate multiple levels of influence on health behavior and are noted for emphasizing the interdependence of environmental settings and life domains. This theory-based article explains how social context is conceptualized in the social sciences and how the social science conceptualization differs from and can broaden the analytic approach to health behavior. The authors use qualitative data from the Behavioral Constructs and Culture in Cancer Screening study to illustrate our conceptualization of social context. We conclude that the incorporation into health behavior theory of a multidimensional socioculturally oriented, theoretical approach to social context is critical to understand and redress health disparities in multicultural societies like the United States.

This article describes the influences of social context on women's health behavior through illustration of the powerful influences of social capital (the benefits and challenges that accrue from participation in social networks and groups) on experiences and perceptions of self-efficacy. The authors conducted inductive interviews with Latino and Filipino academics and social service providers and with U.S.-born and immigrant Latinas and Filipinas to explore direct and indirect influences of social context on health behaviors such as mammography screening. Iterative thematic analysis identified themes (meanings of efficacy, spheres of efficacy, constraints on efficacy, sources of social capital, and differential access to and quality of social capital) that link the domain of social capital with the behavioral construct perceived self-efficacy. The authors conclude that social capital addresses aspects of social context absent in the current self-efficacy construct and that these aspects have important implications for scholars' and practitioners' understandings of health behavior and intervention development.

This article describes how the social context of transculturation (cultural change processes) and transmigration (migration in which relationships are sustained across national boundaries) can directly influence use of mammography screening. The authors conducted semistructured interviews with Latino and Filipino academics and social service providers and with U.S.-born and immigrant Latinas and Filipinas to explore direct and indirect influences of social context on health behavior (Behavioral Constructs and Culture in Cancer Screening study). Iterative analyses identified themes of the transcultural domain: colonialism, immigration, discrimination, and therapeutic engagement. In this domain, the authors examine two key behavioral theory constructs, perceptions of susceptibility to illness and perceptions of benefits of preventive medical care. The findings raise concerns about interventions to promote mammography screening primarily based on provision of scientific information. The authors conclude that social context affects behavior directly rather than exclusively through beliefs as behavioral theory implies and that understanding contextual influences, such as transculturation, points to different forms of intervention.

Research targeting disparities in breast cancer detection has mainly utilized theories that do not account for social context and culture. Most mammography promotion studies have used a conceptual framework centered in the cognitive constructs of intention (commonly regarded as the most important determinant of screening behavior), self-efficacy, perceived benefit, perceived susceptibility, and/or subjective norms. The meaning and applicability of these constructs in diverse communities are unknown. The purpose of this study is to inductively explore the social context of Filipina and Latina women (the sociocultural forces that shape people's day-to-day experiences and that directly and indirectly affect health and behavior) to better understand mammography screening behavior. One powerful aspect of social context that emerged from the findings was relational culture, the processes of interdependence and interconnectedness among individuals and groups and the prioritization of these connections above virtually all else. The authors examine the appropriateness of subjective norms and intentions in the context of relational culture and identify inconsistencies that suggest varied meanings from those intended by behavioral theorists.

The behavioral theory constructs most often used to study mammography utilization-perceived benefit, perceived susceptibility, self-efficacy, intention, and subjective norms-have neither been developed nor sufficiently tested among diverse racial/ethnic subgroups. The authors explored these constructs and their underlying assumptions relating to the social context of Filipina and Latina women. The mixed-methods study included testing construct measures in the multilingual surveys of a concurrent intervention study of 1,463 women from five ethnic groups. An intensive inductive investigation then targeted Latina and Filipina women to elucidate connections between social context and individual screening behavior. In-depth interviews were conducted with 11 key informant scholars, 13 community gatekeepers, and 29 lay women, and a supplemental study videotaped and interviewed 9 mother-daughter dyads. Three social context domains emerged: relational culture, social capital, and transculturation and transmigration. The meaning and appropriateness of the five behavioral constructs were analyzed in relation to these domains. In contradistinction to tenets of behavioral theory, the authors found that social context can influence behavior directly, circumventing or attenuating the influence of individual beliefs; contextual influences, synthesized from multiple perspectives, can operate at an unconscious level not accessible to the individual; and contextual influences are dynamic, contingent on distal and proximal forces coming together in a given moment and are thus not consistent with an exclusive focus at the individual level. This article describes the study methods, summarizes main findings, and preview the detailed results presented in the other articles in this issue.

Intention, self-efficacy, perceived susceptibility, perceived benefits, and subjective norms are key constructs of health behavior theories; their predictive validity for cancer screening has not been ascertained in multiethnic populations. Participants were 1,463 African American, Chinese, Filipina, Latina, and White women aged 40 to 74 interviewed by telephone in their preferred languages. The relationship between baseline constructs and mammography 2 years later was assessed using multivariable logistic regression. Intention predicted mammography overall and among Whites (odds ratio [OR] = 5.0, 95% confidence interval [CI] = 2.4, 10), with racial/ethnic differences in association (p = .020). Self-efficacy predicted mammography overall and among Whites (OR = 3.5, 95% CI = 1.1, 11), with no racial/ethnic interaction. Perceived benefits and subjective norms were associated with screening overall and in some racial/ethnic groups. These results generally support cross-cultural applicability of four of the five constructs to screening with mixed predictive value of measures across racial/ethnic groups. Additional in-depth inquiry is required to refine assessment of constructs.
