BackgroundCommunity-based collaborative approaches have received increased attention as a means for addressing occupational health disparities. Organizational capacity, highly relevant to engaging and sustaining community partnerships, however, is rarely considered in occupational health research. MethodsTo characterize community organizational capacity specifically relevant to Chinese immigrant worker health, we used a cross-sectional, descriptive design with 36 agencies from six community sectors in King County, Washington. Joint interviews, conducted with two representatives from each agency, addressed three dimensions of organizational capacity: organizational commitment, resources, and flexibility. Descriptive statistics were used to capture the patterning of these dimensions by community sector. ResultsOrganizational capacity varied widely across and within sectors. Chinese and Pan-Asian service sectors indicated higher capacity for Chinese immigrant worker health than did Chinese faith-based, labor union, public, and Pan-ethnic nonprofit sectors. ConclusionsVariation in organizational capacity in community sectors can inform selection of collaborators for community-based, immigrant worker health interventions.
