Those in poverty face myriad stressors, traumatic events, and ongoing hardships; and not surprisingly, struggle with a range of mental health issues. Yet, they are less likely to access mental health services than their middle-income counterparts, and when they do, they are more likely to drop out of treatment prematurely. Although researchers have found that when interventions are tailored to address poverty-related stressors outcomes are dramatically improved, the perspectives of those providing such treatment is rarely described. This qualitative descriptive study of twelve experienced psychologists working with clients in poverty aimed to fill this gap. The study explored the extent to which psychologists develop unique practices for working with low-income clients, as well as the personal and contextual factors that support or hinder these efforts. Findings can be distilled into three categories: Practices unique to working with low-income clients include strategies for addressing power dynamics, managing boundaries, and addressing external stressors as part of the therapeutic process. Therapist attributes key to working with low-income clients include possessing a values-based commitment to working with marginalized groups; possessing experience with, knowledge of, and empathy for the realities of living in poverty; possessing a high degree of self-awareness related to poverty; and possessing a willingness to be deeply affected by the work and cope with negative feelings. Contextual obstacles to working with low-income clients include agency-level and social service system-level challenges. Perhaps the most striking finding was participants' understanding of how conceptualizations of appropriate boundaries need to change in the context of work with this population. Many participants described, for example, giving food to their clients when they were hungry or giving them small amounts of money to help them take care of their most basic needs. The discussion section explores these findings in the context of ecological and feminist theoretical models and current research and describes the implications of the results for research, training, and practice.
