Research (e.g. French, Power, & Mitchell, 2000; Harris, 2006; Harris & Alderson, 2006, 2007; Roy & Cain, 2001) has highlighted important benefits for people living with HIV/AIDS to become connected with HIV community-based (CB) agencies (e.g. reduction of isolation, educational opportunities, empowerment). However, CB HIV organizations sometimes experience challenges in recruiting and retaining people living with HIV/AIDS. In a sample of 68 respondents associated with a Canadian HIV/AIDS CB agency, facets of agency identification were examined as correlates of (a) turnover intentions with the agency and (b) aspects of psychological adjustment (hope and general self-efficacy). Results indicated one dimension of social identification, in-group affect, as a significant correlate of turnover intentions (such that members with more positive agency-derived feelings were more likely to say they would stay at the agency), and another emotionally-relevant aspect of identification, in-group ties, as a significant correlate of general self-efficacy. Hope was unrelated to social identification. Several implications for HIV CB agencies are discussed. Copyright © 2010 John Wiley & Sons, Ltd.
