Abstract
The increasing use of pharmacotherapy raises specific ethical concerns for psychologists working with vulnerable populations. Due to a shortage of trained specialists, professionals without training in mental health, such as primary care providers, are increasingly prescribing and monitoring psychotropic medications. Vulnerable populations face additional barriers to mental health treatment and are at heightened risk when these factors intersect. Hence, these patients experience unique barriers to receiving optimal psychopharmacological care and are differentially vulnerable to deleterious outcomes associated with misdiagnosis and overmedication. Taken together, these factors fuel inequities in the access, quality, and utilization of mental health care. Psychologists working with these patients are ethically mandated to protect patients from harm and ensure equitable care across patient populations. Specifically, psychologists must respond to the dilemma of how to effectively treat patients within these vulnerable populations who have been misdiagnosed or poorly medicated while remaining within the bounds of their competence. This article recommends pathways to address these dilemmas through education, training, research, and advocacy.
