Organizations can benefit from being internally diverse, but they may also face significant challenges arising from such diversity. Potential benefits include increased organizational innovation, legitimacy, and strategic capacity; challenges include threats to organizational stability, efficacy, and survival. In this article, we analyze the dynamics of internal diversity within a field of politically oriented civic organizations. We find that "bridging cultural practices" serve as a key mechanism through which racially and socioeconomically diverse organizations navigate challenges generated by internal differences. Drawing on data from extended ethnographic fieldwork within one local faith-based community organizing coalition, we describe how particular prayer practices are used to bridge differences within group settings marked by diversity. Furthermore, using data from a national study of all faith-based community organizing coalitions in the United States, we find that a coalition's prayer practices are associated with its objective level of racial and socioeconomic diversity and its subjective perception of challenges arising from such diversity. Our multi-method analysis supports the argument that diverse coalitions use bridging prayer practices to navigate organizational challenges arising from racial and socioeconomic diversity, and we argue that bridging cultural practices may play a similar role within other kinds of diverse organizations.

Purpose Identify and compare predictors of the existence of congregational HIV and other health programs. Design Cross-sectional study. Setting United States. Participants A nationally-representative sample of 1,506 U.S. congregations surveyed in the National Congregations Study (2006-07). Measures Key informants at each congregation completed in-person and telephone interviews on congregational HIV and other health programs and various congregation characteristics (response rate = 78%). County-level HIV prevalence and population health data from the Robert Wood Johnson Foundation's 2007 County Health Rankings were linked to the congregational data. Analysis Multinomial logistic regression was used to assess factors that predict congregational health programs relative to no health programs; and of HIV programs relative to other health activities. Results Most congregations (57.5%) had at least one health-related program; many fewer (5.7%) had an HIV program. Predictors of health vs. HIV programs differed. The number of adults in the congregation was a key predictor of health programs, while having an official statement welcoming gay persons was a significant predictor of HIV programs (p<.05). Other significant characteristics varied by size of congregation and type of program (HIV vs. other health). Conclusion Organizations interested in partnering with congregations to promote health or prevent HIV should consider congregational size as well as other factors that predict involvement. Results of this study can inform policy interventions to increase the capacity of religious congregations to address HIV and health.

The ambivalent response of many black churches to current social issues has caused some scholars to question the centrality of black churches within African-American communities. Using a nationally representative sample of black congregations, this study engages the debate about the institutional centrality of black churches by focusing on their response to HIV/AIDS. Although many congregational studies treat black churches as a monolithic whole, this analysis identifies heterogeneity among black churches that shapes their responsiveness to social issues. Contrary to prior claims, a congregation's liberal-conservative ideological orientation does not significantly affect its likelihood of having an HIV/AIDS program. Beyond assessing churches’ internal characteristics, this study uses institutional theory to analyze churches as open systems that can be influenced by their surrounding environment. It demonstrates that externally engaged congregations are significantly more likely to have a program. These results indicate that black churches maintain institutional centrality by engaging their external environment.

Surveys provide a critical source of data for scholars, yet declining response rates are threatening the quality of data being collected. This threat is particularly acute among organizational studies that use key informants—the mean response rate for published studies is 34 percent. This article describes several response enhancing strategies and explains how they were implemented in a national study of organizations that achieved a 94 percent response rate. Data from this study are used to examine the relationship between survey response patterns and nonresponse bias by conducting nonresponse analyses on several important individual and organizational characteristics. The analyses indicate that nonresponse bias is associated with the mean/proportion and variance of these variables and their correlations with relevant organizational outcomes. After identifying the variables most susceptible to nonresponse bias, a final analysis calculates the minimum response rate those variables needed to ensure that they do not contain significant nonresponse bias. Heuristic versions of these analyses can be used by survey researchers during data collection (and by scholars retrospectively) to assess the representativeness of respondents and the degree of nonresponse bias variables contain. This study has implications for survey researchers, scholars who analyze survey data, and those who review their research.
