"For this paper, you are to identify and summarize FOUR empirical, peer-reviewed articles which evaluate the impact of an intervention, program, or policy to address homelessness. The intervention, program, or policy can be at any (and at multiple) levels of the ecological model. In keeping with the theme of the course, please do NOT limit yourself to research on individual-level interventions. My expectation is that the bulk or all of the research you identify for inclusion in your paper will be drawn from community or applied social psychology journals."
